UNIT 20 Present perfect (I have done) or simple past (I did)?　
　a. It is often possible to use the present perfect (I have done) or the simple past (I did).　　
I’ve lost my key. Have you seen it anywhere?
　　 or I lost my key. Did you see it anywhere?
　　But do not use the present perfect to say when something happened (for example, yesterday, two years ago, when I was a child, etc.). Use a past tense in these sentences:　　
I lost my key yesterday. (not have lost)
　　 Did you see the movie on TV last night? (not have you see)
　　 I ate a lot of candy when I was a child. (not have eaten)
　　Use a past tense to ask when or what time something happened:　　
What time did they arrive? (not have they arrived)
　　 When were you born? (not have been born)
　　
　　b. Do not use the present perfect (I have done) for happenings and actions that are not connected with the present (for example, historical events):　　
The Chinese invented printing. (not have invented)
　　 How many symphonies did Beethoven compose? (not has…composed)
　　
　　
　　c. Now compare these sentences:　　
　　Present perfect (I have done)
　　I’ve smoked 20 cigarettes today.
　　Today is a period of time that continues up to the present. It is not a finished time. So we use the present perfect.
　　Dan hasn’t been sick this year.
　　Have you seen Ann this morning?
　　(It is still morning.)
　　Have you seen Ann recently?
　　We’ve been waiting for an hour. (We are still waiting.)
　　Pierre has lived in Quebec for six years. (He still lives there)
　　I have never played golf (in my life).
　　
　　The present perfect always has a connection with the present.
　　See Units 13-19
　　Simple past (I did)
　　I smoked 20 cigarettes yesterday.
　　Yesterday is a finished time in the past. So we use the simple past.
　　Dan wasn’t sick last year.
　　Did you see Ann this morning? (It is now afternoon)
　　Did you see Ann last week?
　　We waited (or were waiting) for an hour. (We are no longer waiting)
　　Pierre lived in Quebec for ten years. (He no longer lives there.)
　　I didn’t play golf when I was on vacation last summer.
　　
　　The simple past tells us only about the past.　　See Unit 11-12

UNIT 21 Past perfect (I had done)　
　a. Study this example situation:　　
I went to a party last week. Tom went to the party too. Tom went home at 10:30. So, when I arrived at 11:00, Tom wasn’t there.
　　When I arrived at the party, Tom wasn’t there. He had gone home.
　　This is the past perfect (simple) tense:
　　I/he/she (etc.) had (= I’d/he’d/she’d, etc.) gone
　　I/he/she (etc.) hadn’t gone
　　had you/he/she (etc.) gone?
　　We form the past perfect with had + the past participle (gone/opened/written, etc.). For irregular past participles see Appendix 2.
　　Sometimes we talk about something that happened in the past:
　　 I arrived at the party.
　　We use the past perfect to say that something had already happened before this time:　　
When I arrived at the party, Tom had already gone home.
　　Here are some more examples:
　　 When I got home, I found that someone had broken into my apartment and had stolen my fur coat.
　　 George didn’t want to come to the movies with us because he had already seen the film twice.
　　 It was my first time in an airplane. I was very nervous because I had never flown before.
　　
　　b. The past perfect (I had done) is the present perfect (I have done). Compare these situations:　　
　　Present
　　I’m not hungry. I’ve just had lunch.
　　The house is dirty. We haven’t cleaned it for weeks.
　　Past
　　I wasn’t hungry. I’d just had lunch.
　　The house was dirty. When hadn’t cleaned it for weeks.
　　
　　
　　c. Compare the past perfect (I had done) and the simple past (I did):　　
“Was Tom there when you arrived?” “No, he had already gone home.”
　　 but: “Was Tom there when you arrived?” “Yes, but he went home soon afterward.”
　　 Ann wasn’t home when I called her. She was at work.
　　 but: “Ann had just gone home when I called her. She had been at work.”
　　 For the past perfect continuous see Unit 22.

　　UNIT 21 Exercises　　
21.1 Complete these sentences using the verbs in parentheses (…).
You went back to your home town after many years, and you found that many things were different.

　　2. We arrived at the theater late. (the movie/already/begin) ________________________
　　3. They weren’t eating when I went to see them. (they/just/finish/their dinner) ________________________
　　4. I invited Ann to dinner last night, but she couldn’t come. (she/already/make plans/to do something else)
　　5. I was very pleased to see Diane again after such a long time. (I/not/see/her for five years)
　　
　　21.4 Put the verb into the correct form: past perfect (I had done) or simple past (I did).　　
Examples: “Was Tom there when you arrived?” “No, he had gone (go) home.”
　　 “Was Tom there when you arrived?” “Yes, but he went (go) home soon afterward.”
　　1. The house was very quiet when I got home. Everybody __________ (go) to bed.

UNIT 22 Past perfect continuous (I had been doing)

UNIT 24 Used to (I used to do)　
　a. Study this example situation:　　
This is Dennis. He gave up smoking two years ago. He no longer smokes.
　　 But he used to smoke. He used to smoke 40 cigarettes a day.
　　 He used to smoke means that he smoked regularly for some time in the past, but he doesn’t smoke now.
　　 We use used to with the base form (used to do/used to smoke, etc.) to say that something happened regularly in the past but no longer happens:
　　 I used to play tennis a lot, but now I’m too lazy.
　　 “Do you go to the movies very often?” “Not now, but I used to.”
　　 Sue used to travel a lot. These days she doesn’t go away very often.
　　 We also use used to for past situations (that no longer exist):
　　 We used to live in a small village, but now we live in Milan.
　　 This building is now a furniture store. It used to be a movie theater.
　　 Do you see that hill over there? There used to be a castle on that hill.
　　 I’ve started drinking tea lately. I never used to like it before.
　　 Ann used to have long hair, but she cut it some time age.
　　
　　b. Used to + base form is always past. There is no present. You cannot say “I use to do.” For the present, use the simple present (I do). Compare the present and past:
　　Past he used to smoke we used to live there used to be
　　Present he smoke we like there is
　　
　　c. The normal question form is did … use to …?:
　　 Did you use to eat a lot of candy when you were a child?
　　 The negative form is didn’t use to … (or never used to)
　　 Jim didn’t use to go out very often until he met Jill. (or never used to go out)
　　
　　d. Be careful not to confuse I used to do and I am used to doing (see Unit 59). The structures and meanings are different:
　　 I used to live alone. (= I lived alone but I no longer live alone.)
　　 I am used to living alone. (= I live alone and don’t find it strange or new because I’ve been living alone for some time.)

　　 Be able to is possible instead of can, but can is more usual:

　　 I haven’t been able to sleep recently. (can has no present perfect)
　　 Sue might not be able to come tomorrow. (can has no infinitive)
　　 I’m very busy today, but I should he able to meet with you tomorrow.

UNIT 26 Could (do) and could have (done)　　
a. Study this example:　　
Dan: What do you want to do this evening?
　　Sue: We could go to the movies.
　　We use could (do) in a number of ways. Sometimes it is past of can (do) (see Unit25), but sometimes it has a present of future meaning.
For example, we sometimes use could to talk about possible future actions, especially when we make suggestions:
　　“When you go to New York, you could stay with Linda.”
　　Can is also possible in these sentences. (“We can go to the movies”)
　　Could is more unsure than can.
　　We also use could to talk about possible future happenings:
　　 There could be another rise in the price of gas soon. (= It is possible that there will be.)
　　Sometimes could means would be able to:
　　 Why doesn’t Tom apply for the job? He could get it.
　　 I don’t know how she works 14 hours a day. I couldn’t do it.
　　
　　b. The past of could (do) is could have (done). We use could have (done) to say that we had the ability or the opportunity to do something but did not do it
　　 We didn’t go out last night. We could have gone to the movies, but we decided to stay home.(我觉得应该是stay at home,not sure) (We had the opportunity to go out, but we didn’t.)
　　 Why did you stay at a hotel in New York? You could have stayed with Linda. (You had the opportunity to stay with her you didn’t.)
　　 Why didn’t Tom apply for the job? He could have gotten it. (He had the ability to get it.)
　　
　　c. Here are some examples of couldn’t have (done). “I couldn’t have done something” = I wouldn’t have been able to do it if I had wanted or tried to do it:　　
When I went to New York last year, I decided not to stay with Linda. Later I found out that she was away while I was there, so I couldn’thave stayed with her anyway.
　　 The hockey game was canceled last week. Tom couldn’t have played anyway because he was sick.
　　
　　For could/couldn’t see also Units 25, 27b, 28c, 30.
　　For could in if sentences see Units 34—35 and 36c.
UNIT 26 Exercises　　
26.1 Make suggestions. Use could.

　　1. What should we have for dinner tonight? (fish) ________________________
　　2. When should we go and see Tom? (on Friday) ________________________
　　3. What should I give Ann for her birthday? (a book) ________________________
　　
　　26.2 Use could have. Answer the questions in the way shown.

　　 Ken doesn’t know anything about machines.
　　 Ken can’t drive.

　　A lot of people wanted Ken of do different things last week, but they couldn’t contact him. So he didn’t do any of these things. Say whether he could have done or couldn’t have done these things (if he had known).
　　Example: His aunt wanted him to drive her to the station.
　　 He couldn’t have driven her to the station (because he can’t drive).

UNIT 31 Have to and must　
　a. We use have to (do) and must (do) to say that it is necessary to do something:　　
Oh, it’s later than I thought. I have to go now.
　　 must
　　 You have to have a passport to visit most foreign countries.
　　 Must
　　 There is sometimes a difference between must and have to. With must the speaker is expressing personal feelings, saying what he or she thinks is necessary:　　
I must write to Ann. I haven’t written to her for ages. (= The speaker personally feels that he or she must write to Ann.)
　　 The government really must do something about unemployment. (= The speaker personally feels that the government must do something.)
　　 With have to the speaker is not expressing feelings. The speaker is just giving facts.
For example:
　　 Karen’s eyes are not very good. She has to wear glasses for reading.
　　 I can’t meet you on Friday. I have to work.
　　
　　b. You use must to talk only about the present and future:　　
We must go now.
　　 Must you leave tomorrow?
　　 Have to can be used in all forms. For example:　
　 I had to go to the hospital. (past)
　　 I might have to go to the hospital. (base form)
　　 Have you ever had to go to the hospital? (present perfect)
　　 Note that we use do/does/did with have to in question and negative sentences:
　　 What do I have to do to get a driver’s license? (not “have I to do”)
　　 Why did you have to go to the hospital? (not “had you to go”)
　　 Tom doesn’t have to work on Saturdays. (not “hasn’t to work”)
　　
　　c. Mustn’t and don’t have to are completely different. “You mustn’t do something” means “it is necessary that you do not do it”:
　　 You mustn’t tell anyone what I said. (= Don’t tell anyone.)
　　 I promised I’d be on time. I mustn’t be late. (= I must be on time.)
　　 “You don’t have to do something” means “it is not necessary to do it; you don’t need to do it:”
　　 I don’t have to wear a suit to work, but I usually do.
　　 She stayed in bed this morning because she didn’t have to go to work.
　　
　　d. You can use “have got to” instead of “have to.” So you can say:　　
I’ve got to work tomorrow. or I have to work tomorrow.
　　
UNIT 31 Exercises　
　31.1 Complete these sentences with must or have to (in its correct form). Sometimes it is possible to use either; sometimes only have to is possible.

　　1. You really _______________ work harder if you want to pass that exam.

　　3. “George had to pay a parking fine.” “How much ______________________________”
　　4. “I have get up early tomorrow.” “Why ______________________________”
　　
　　31.3 Make negative sentences with have to.　　
Example: “Did they changes planes?”
　　 “No, it was a direct flight, so they didn’t have to change planes.”
　　1. “Did you pay to get into the concert?” “No, we had free tickets, so we ___________________”

UNIT 32 Should
　　a. Study this example:　
　 Tom has just come back from the movies:
　　 Ann: Hello, Tom. Did you enjoy the movie?
　　 Tom: Yes, it was great. You should go and see it.
　　 Tom is advising Ann to go and see the movie. “You should go” means that it would be a good thing to do. We often use should (do) when we say what we think is a good thing to do or the right thing to do.　
　 The government should to do something about economy.
　　 “Should we invite Sue to the party?” “Yes, I think we should.”
　　 “You shouldn’t do something” means that it is not a good thing to do:
　　 You’ve been coughing a lot lately. You shouldn’t smoke so much.
　　 Tom really shouldn’t go out. He has too much homework to do.
　　 Should is not as strong as must:
　　 You should stop smoking. (= It would be a good idea.)
　　 You must stop smoking. (= It is necessary that you stop.)
　　
　　b. We often use should when we ask for or give an opinion about something. Often we use I think/I don’t think/do you think? :　　 I think the government should do something about the economy.
　　 I don’t think you should work so hard.
　　 “Do you think I should apply for this job?” “Yes, I think you should.”
　　
　　c. We also use should to say something is not “right” or not what we expect:　　
The price on this package is wrong. It says 65¢ but it should be 50¢.
　　 Those children shouldn’t be playing. They should be at school.
　　d. For the past, we use should have (done) to say that someone did the right or wrong thing:　　
The party was great. You should have come. Why didn’t you?
　　 I feel sick. I shouldn’t have eaten so much chocolate.
　　 She shouldn’t have been listening to our conversation. It was private.
　　
　　e. We also use should to say that something will probably happen:　　
A: Do you think you’ll be home late night?
　　 B: I don’t think so. I should be home at the usual time.
　　 Here, “I should be home” means “I will probably be home.” You can use should to say what will probably happen.
　　
　　f. You can use ought to instead of should in the sentences in this unit:　　
It’s really a good movie. You ought to go and see it.
　　 She’s been studying very hard, so she ought to pass the exam.

UNIT 32 Exercises　
　32.1 You are giving advice to a friend. Use should or shouldn’t.
　　 Example: Your friend is always coughing because he smokes too much. Advise him to stop smoking. You should stop smoking.
　　1. Your friend has a bad toothache. Advise her to go the dentist. You ________________________.
　　2. You friend rides his bicycle at night without lights. You think this is dangerous. Advise him not to do it. _____________________________
　　3. Your friend is going to visit Greece. Advise her to learn a few words of Greek before she goes.
　　 __________________________________________________________
　　
　　32.2 This time give your opinion about something. Use I think/I don’t think …　
　 Example: Tom has just been offered a job. You think it would be a good idea for him to accept it. I think Tom should accept the job.
　　1. You think it would be a good idea for all drivers to wear seat belts.
　　I think __________________________________________________________
　　2. You don’t think it would be a good idea for Jill and Sam to get married.
　　I __________________________________________________________
　　3. Your friend has a bad cold. Tell him that you think it would be a good idea for him to stay home tonight. __________________________________________________________
　　
　　32.3 Read the situations and write sentences with should (have) and shouldn’t (have). Sometimes you have to use the present, sometimes the past.
　　 Examples: The speed limit in 55 miles an hour, but Tom is doing 70. He shouldn’t be driving so fast.
　　 When we got to the restaurant there were no empty tables. We hadn’t reserved one. We should have reserved a table.
　　1. It’s very cold. Mrs. Taylor, who has been sick lately, she is standing at the bus stop without a coat. She __________________________________________________________

　　c. other structures are possible after insist and suggest:　　
They insisted on my having dinner with them. (see Unit 57a)

　　 What do you suggest I do? (not suggest me to do)
　　
　　d. Should is something used instead of the subjunctive.

UNIT 34 If sentences (present/future)　
　a. Compare these examples:　　
Tom: I think I left my lighter at your house. Have you seen it?
　　 Ann: No, but I’ll look. If find it, I’ll give it to you.
　　 In this example there is a real possibility that Ann will find the lighter. So she says: “If I find … I’ll …” (see also Unit 9c).
　　 When you imagine a future happening like this, you use a past tense form (did/came/found, etc.) after if. But the meaning is not past:
　　 What would you do if you won a million dollars?
　　 If we didn’t go to their party next week, they would be very angry.
　　 Ann wouldn’t lend me any money if I asked her.
　　
　　b. We do not normally use would in the if part of the sentence:　
　I’d be very frightened if someone pointed a gun at me. (not if someone would point)
　　If we didn’t go to their party next week, they would be very angry. (not if we wouldn’t go)
　　Sometimes it is possible to say if … would, especially when you ask someone to do something in a formal way:
　　 I would be very grateful if you would send me your brochure and price list as soon as possible. (from a formal letter)
　　
　　c. In the order part of the sentence (not the if part) we use would/wouldn’t. Would is often shortened to ’d, especially in spoken English:　　
If you stopped smoking, you’d probably feel healthier.
　　 They wouldn’t come to the party if you invited them.
　　 You can also use could and might:
　　 They might be angry if I didn’t visit them. (= perhaps they would be)
　　 If it stopped raining, we could go out. (= we would be able to go out)
　　
　　d. Do not use when in sentences like the ones in this unit:　　
Tom would be angry if I didn’t visit him. (not when I didn’t visit)
　　 What would you do if you were bitten by a snake? (not when you were)
　　 See also Unit 9c.
　　 For if sentences see also Units 35 and 36.

UNIT 34 Exercises
　　34.1 Put the verb into the correct form.
　　 Example: If I found a $100 bill on the street, I would keep (keep) it.
　　 They’d be very angry if you didn’t visit (not/visit) them.
　　1. If the company offered me the job, I think I ________ (take) it.
　　2. I’m sure Liz will lend you some money. I would be very surprised if she ________ (refuse).
　　3. Many people would be out of work if that factory ________ (close) down.
　　4. If she sold her car, she ________ (not/get) much money for it.
　　5. They’re expecting us. They would be disappointed if we ________ (not/come).
　　6. Would George be angry if I ________ (take) his bicycle without asking?
　　7. Ann gave me this ring. She ________ (be) terribly upset if I lost it.
　　8. If someone ________ (walk) in here with a gun, I’d be very frightened.
　　9. What would happen if you ________ (not/go) to work tomorrow?
　　10. I’m sure she ________ (understand) if you explained the situation to her.
　　
　　34.2 Make questions.
　　 Example: Perhaps one day somebody will give you a lot of money.
　　 What would you do if someone gave you a lot of money?
　　1. Perhaps one day a millionaire will ask you to marry him/her.
　　What would you do if ________________________________
　　2. Perhaps one day you will lose your passport in a foreign country.
　　What ________________________________
　　3. Perhaps one day somebody will throw an egg at you.
　　What ________________________________
　　4. Perhaps one day your car will be stolen.
　　What ________________________________
　　5. Perhaps one day somebody will park a car on your foot.
　　 ________________________________
　　
　　34.3 Answer these questions in the way shown.　　
Example: Are you going to take the 10:30 train? (we/arrive too early)
　　 No. If we took the 10:30 train, we would arrive too early.
　　1. Is the going to take the exam? (he/fail it) No. If he ________________________________

UNIT 35 If and wish sentences (present)
　　a. Study this example situation:
　　 Tom wants to call Sue, but he can’t because he doesn’t know her telephone number.
　　 He says: If I knew her number, I would call her.
　　 Tom says “If knew her number…” This tells us that he doesn’t know her number.
　　 He is imagining the situation. The real situation is that he doesn’t know her number.
　　 When you imagine a situation like this, you use a past tense form (“I did/I had/I knew,” etc.) after if. But the meaning is present, not past:　　
Tom would travel if he had more money. (but he doesn’t have much money)
　　 If I didn’t want to go, I wouldn’t. (but I want to go)
　　 We wouldn’t have any money if we didn’t work. (but we work)
　　
　　b. We also use the past for a present situation after wish. We use wish to say that we regret something, that something is not as we would like it to be:
　　 I wish I knew Sue’s telephone number. (I don’t know it.)
　　 Do you ever wish you could fly? (You can’t fly.)
　　 I wish it didn’t rain so much in this city. (It rains a lot.)
　　 It’s crowded here. I wish there weren’t so many people. (There are a lot of people.)
　　 I wish I didn’t have to work. (I have to work.)
　　
　　c. In if sentences and after wish we use were instead of was:　　
If I were you, I wouldn’t buy that coat. (but I am not you)
　　 I’d go out if it weren’t raining. (but it is raining)
　　 I wish my room were larger. (but it isn’t very larger)
　　
　　d. Do not use would in the if part of the sentence or after wish:
　　 If I were rich, I would buy a castle. (not if I would be rich)
　　 I wish I were taller. (not I wish I would be taller.)
　　 But sometime I wish… would… is possible. See Unit 37.
　　 Could sometimes means “would be able to” and sometimes “was able to”:　　
She could (= would be able to) get a job more easily if she could (= was able to) type.
　　For if sentences and wish see also Units 34,36, and 37.

UNIT 35 Exercises　
　35.1 Put the verb into the correct form.

这些记不得，还不如多听

不觉得有矛盾，听挺重要，语感也重要，不过这么多年了，学校学的最拿手的语法忘了差不多了，现在重温一下，我觉得对写作有帮助。

UNIT 36 If and wish sentences (past)　
　a. Study this example situation:　　
Last month Ann was sick. Tom didn’t know this, and he didn’t go to see her. They met again after Ann got better. Tom said:
　　 If I had known that you were sick. I would have gone to see you.
　　 The real situation was that Tom didn’t know Ann was sick. So he says If I had know…
　　 When you are taking the past, you use the past perfect (I had done/I had been/I had known, etc.) after if.
　　 If I had seen you when you passed me in the street, I would have said hello. (but I didn’t see you)
　　 I would have gone out if I hadn’t been so tired. (but I was too tired)
　　 If he had been looking where he was going, he wouldn’t have walked into the wall. (but he wasn’t looking)
　　 Do not use would (have) in the if part of the sentence:　　
If I had seen you, I would have said hello. (not if I would have seen)
　　 Both would and had can be shortened to ’d:　　
If I ’d see (= had seen) you, I’d have said (= would have said) hello.

　　b. Use the past perfect (I had done) after wish when you say that you regret something that happened or didn’t happen in the past:　　 I wish I had known that Ann was sick. I would have gone to see her. (I didn’t know that she was sick.)
　　 I feel sick. I wish I hadn’t eaten so much. (I ate too much.)
　　 Do you wish you had studied science instead of languages? (You didn’t study science.)
　　 The weather was terrible. I wish it had been warmer. (It wasn’t warm.)
　　 You cannot use would have after wish:
　　 I wish it had been warmer. (not would have been)
　　
　　c. Would have (done) is the past form of would (do):　　
If I had gone to the party last night, I would be tired now. (I am not tired now – present.)
　　 If I had gone to the party last night, I would have seen Ann. (I didn’t see Ann - past)
　　 Might have and could have are possible instead of would have:　
　 If we’d played better, we might have won. (= perhaps we would have won)
　　 We would have gone out if the weather hadn’t been so bad. (= we would have been able to go out)
　　 For if sentences and wish see also Units 34, 35, and 37.

UNIT 37 Would　　
For would and would have in if sentences (conditional), see Units 34,35, and 36. For would in offers, invitations, etc., see Unit 30. This unit explains some other uses to would.
　　a. Sometimes we use would after I wish… Study this example:
　　 It is raining. Tom wants to go out, but not in the rain. He says: I wish it would stop raining.
　　 This means that Tom is complaining about the rain and wants it to stop. We use I wish… would… when we want something to happenor somebody to do something. The speaker is complaining about the present situation.　
　 I wish someone would answer that telephone. It’s been ringing for about five minutes.
　　 The music next door is very loud. I wish they would turn it down.
　　 We often use I wish… would when we want something to change or somebody else to do something. So you cannot say “I wish I would…” 　　For more information about wish, see Units 35, and 36.
　　
　　b. Would/wouldn’t is sometimes the past of will/won’t:　　
Present Tom: I’ll lend you some money, Ann.

　　Present Ann: I promise I won’t be late.
　　Past Ann promise that she wouldn’t be late.
　　Present Tom: Darn it! The car won’t start.
　　Past Tom was angry because the car wouldn’t
　　
　　c. You can also use would when you look back on the past and remember things that often happened:　　
When we were children, we lived by the sea. In summer, if the weather was nice, we would all get up early and go for a swim.
　　 Whenever Linda was angry, she would just walk out of the room.
　　 Used to is also possible in these sentences:
　　 … we all used to get up early and go …
　　See Unit 24 for used to

　　UNIT 37 Exercises

UNIT 38 In case　
　a. Study this example situation:
　　 Jeff is soccer referee. He always wears two watches during a game because it is possible that one watch will stop.
　　 He wears two watches in case one of them stops.
　　 In case one of them stops = “because it is possible that one of them will stop.”
　　 Here are some more examples of in case:
　　 John might call tonight. I don’t want to go out in case he calls.
　　 (= because it is possible that he will call)
　　 I’ll draw a map for you in case you can’t find our house.
　　 (= because it is possible that you won’t be able to find it)
　　
　　b. Do not use will after in case. Use a present tense when you are talking about the future;　　
I don’t want to go out tonight in case Sue calls. (not “in case she will call”)
　　
　　c. In case is not same as if. Compare these sentences:
　　 We’ll buy some more food if Tom comes. (= Perhaps Tom will come; if he comes, we’ll buy some more food; if he doesn’t come, we won’t buy any more food.)
　　 We’ll buy some more food in case Tom comes. (= Perhaps Tom will come; we’ll buy some more food now, whether he comes or not; then we’ll already have the food if he comes.)
　　 Compare:
　　 This letter is for Ann. Can you give it to her if you see her?
　　 This letter is for Ann. Can you take it with you in case you see her?
　　
　　d. You can use in case to say why someone did something in the past:　　
We bought some more food in case Tom came. (= because it was possible that Tom would come)
　　 I drew a map for her in case she couldn’t find our house.
　　 We rang the bell again in case they hadn’t heard it the first time.
　　
　　e. “In case of …” is different from in case. In case of fire means “if there is a fire”:
　　 In case of fire, please leave the building as quickly as possible.
　　 In case of emergency, telephone this number. (= if there is an emergency)
