     UNIT 1 - Page 2

   Transform the following sentences into the negative and the interrogative.

12 Example: (See unit 7, part 10.)
   They'll go/They will go.
   They won't go/They will not go.
   Will they go?

a  He'll get back early.
b  Tom will drop us a line.
c  She'll beat you at chess.
d  It'll be postponed.
e  She'll ask for it.

13 Example: (See unit 22, sections 10 and 11.)
   He may come back. (possibility)
   He may not come back. (May not is not usually contracted.)
   Do you think (that) he will come back? (Avoid May he...?, as it is very unusual for possibility. Compare this section with section 15 in unit 2.)

a  He may speak out against the closure of the factory at tomorrow's meeting.
b  They may denounce him to the police as a bank robber.
c  We may stay here for good.
d  She may look us up the next time she comes to our town.
e  He may forgive them if they speak frankly.

14 Example: (See unit 22, sections 10 and 11.)
   He might come back. (Might suggests a smaller possibility than may.)
   He might not come back. (Mightn't is possible, but not very usual.)
   Do you think (that) he will come back?

a  The sky might be overcast tomorrow.
b  It might be cloudy this afternoon.
c  It might be your aunt.
d  She might pass her examination.
e  They might win the race.

15 Could is the past or conditional form of can. We generally prefer cannot to could not for possibility and permission1:
   They could need another blanket tonight. (possibility)
   They cannot/can't need another blanket tonight.
   Do you think they could need another blanket tonight?
   He could use her car tomorrow. (permission and suggestion)
   He cannot/can't use her car tomorrow.
   Could he use her car tomorrow?

   However, cannot is not possible when the meaning of could is past:
   He could read when he was four. (past ability)
   He couldn't/could not read when he was four.
   Could he read when he was four?

   Cannot is impossible if we have an if-clause with a past tense or a past perfect tense:
   He could do it for you if he had time.
   He couldn't/could not do it for you if he had time.
   Could he do it for you if he had time?

a  He could take my father's van if he had a driving-licence. (an if-clause with a past tense)
b  We could take an extra lump of sugar. (permission and suggestion)
c  She could follow my advice. (possibility)
d  I could swim very well when I was a child. (past ability)
e  It could be too late now. (possibility)

16 Revision exercise.

17 Example:
   You must come to class in good time.
   You needn't/need not come to class in good time.
   Must/Need you come to class in good time?

   Semantically speaking, the opposite of must for obligation or strong advice is need not; must not has a different meaning (prohibition). See unit 22, sections 19, 20, 21, 24, 25, 26 and 27.

a  They must come to our aid.
b  He must take exercise.

   Should he sing at the concert?
   He ought to go there in her place.
   He oughtn't/ought not to go there in her place.
   Ought he to go there in her place?

   Should and ought to are usually interchangeable. See unit 22, sections 26, 27, 29, 30, 31 and 33.

a  They should grow vegetables.
b  He should go jogging tomorrow.
c  We ought to leave now.

   She'd go abroad if she had enough money.
   She wouldn't/would not go abroad if she had enough money.
   Would she go abroad if she had enough money?

   Would is the conditional or past form of will. See example 12 in this unit, and units 7 (part 14) and 9 (section 71).

a  He would shut up if he were you.
b  He would leave that paragraph out.
c  They'd call Margaret up if she had a phone.
