Conditional sentences

Type 1 conditionals

Type 1 conditionals, basic uses: 'If the weather clears, we'll go for a

Walk' [> LEG 14.4-6]

1 We can use all present tenses after if, not just the simple present, for example:

If she finishes work early, she will go home. (if+ simple present + will)

If she has finished work by 4 o'clock, she will go home, (if + present perfect + will)

2 We can use all future tenses in the main clauses, not just the w/'//-future:

If he doesn't hurry, the plane will have left by the time he gets to the airport.

3 We use Type 1 conditionals to describe what will or won't (probably) happen:

If the weather clears, we'll go for a walk. (Not *If the weather will clear")

Write: Supply the correct forms of the missing verbs.

1 If it (be) fine tomorrow, we (go) for a picnic.

2 If I (have) time tonight, I (finish) the novel I'm reading.

3 If it (rain) next weekend, we (not able to) plant the vegetables.

4 If he (be leaving) at 6 o'clock, I (ask) him to give me a lift.

5 If she (have drive) all that way since this morning, (be) tired and hungry.

6 If they (have/be working) all afternoon, they (probably need) a cup of tea.

7 If I (can't/finish) the job this weekend, I (try) to get it done during the week.

8 If John (be picked) for the team, he (be boasting) about it for weeks!

Write:

'If + present + modal: 'If it's fine tomorrow, we may go for a swim'

[> LEG 14.7]

When we use will in the main clause, we are expressing certainty or near-certainty:

If the weather clears, we'll go fora walk, (certain, or nearly certain) [> 11.4A]

If we do not feel 'certain' enough to use will, we can use another modal to say what is possible,

necessary or desirable, for example:

If it's fine tomorrow, we may go for a swim, (it's possible)

If it's fine tomorrow, we must go for a swim, (it's necessary or desirable to do this)

Supply the correct forms of the missing verbs, but use these modals in the main clause:

can, could, may, might, should, ought to, or must. Alternatives are possible.

1 If you (be) still ill tomorrow, you stay at home.

2 If you (finish) work early, you come for a drink with us.

3 If she (have) too much to do, she ask someone to help her.

4 If he (not be coming) tonight, he come next week.

5 If he (have only just arrive), he not have heard the news.

6 If they (have be/waiting) longer than an hour, they be getting impatient.

7 If we (can't/go) next week, we manage to go the week after.
