I Can See It Coming Back Again

English language Grammar IN Utilize FOR INTERMEDIATE

25. When I do/ When I've done When and If

A

Study this example:

'I'll phone you when I go home' is a judgement with two parts:

· the primary function: I' ll phone you and

· the when -part: when I get home

The fourth dimension in the sentence is future (tomorrow), but we use a present tense (I go ) in the when -part of the sentence.

We do not use volition in the when -part of the sentence.

Some more examples:

· Nosotros' ll go out when it stops raining. (not when it volition stop)

· When y'all are in London again, come and see the states. (not When you will exist)

· (said to a child) What practice you want to be when you grow up? (not volition abound)

The same thing happens after while /before /after /as soon as /until or till:

· What are you going to do while I'm away? (not while I volition be)

· I'll probably become back home on Sunday. Before I go , I'd like to visit the museum.

· Wait hither until (or till ) I come back.

B

Y'all can likewise employ the present perfect ( have done ) after when /after /until /as shortly every bit :

· Can I borrow that volume when you' ve finished with it?

· Don't say anything while Ian is here. Wait until he has gone .

If you use the present perfect, i thing must be complete before the other (so the two things do not happen together):

· When I've phoned Kate , we can have dinner. (= First I'll phone Kate and later that nosotros can have dinner.)

Do not use the nowadays perfect if the ii things happen together:

· When I phone Kate, I'll ask her about the party. (non When I've phoned)

It is oftentimes possible to use either the present unproblematic or the present perfect:

· I'll come equally before long as I finish . or I'll come every bit soon as I've finished .

· You'll feel better after you have something to swallow. or You'll feel amend after you've had something to eat.

C

After if , nosotros commonly use the present simple (if I do / if I meet etc.) for the future:

· It'due south raining hard. We'll get wet if we go out. (not if nosotros will go)

· I'll be angry if it happens again. (non if information technology will happen)

· Hurry up! If nosotros don't hurry , we'll exist late.

D

When and if

We use when for things which are certain to happen:

· I'm going out later. (for sure) When I become out, I'll get some bread.

We utilise if (non when) for things that will possibly happen:

I might go out afterwards. (information technology'due south possible) If I go out, I'll become some bread.

If information technology is raining this night, I won't go out. (not When it is raining)

Don't worry if I'thousand belatedly tonight. (not when I'chiliad late)

If they don't come soon, I'thou not going to wait. (not When they don't come)
