Unit 38. If I do ... and If I did ...




Unit 38; Part A

galka.jpgCompare these examples:
(1) 
Lisa has lost her watch. She tells Sue:
        Lisa: I've lost my watch. Have you seen it anywhere?
        Sue: No, but if I find it, I'll tell you.

In this example, Sue feels there is a real possibility that she will find the watch. So she says: if I find..., I'll... .

(2)  
Joe says:
        If I found a wallet in the street, I'd take it to the police station.
This is a different type of situation. Here, Joe doesn't expect to find a wallet in the street: he is imagining a situation that will probably not happen.38.1.jpg So he says: if I found ... , I'd (= I would) ... .  (not if I find ... , I'll ...)

When you imagine something like this, you use if + past
(if I found / if there was / if we didn't etc.). But the meaning is not past:
•    What would you do if you won a million pounds? (we don't really expect this to happen)
•    I don't really want to go to their party, but I probably will go. They'd be upset if I didn't go.
•    If there was (or were) an election tomorrow, who would you vote for?


For if ... was/were, see Unit 39C.

Unit 38; Part B

galka.jpgWe do not normally use would in the if-part of the sentence:

•   
I'd be very frightened if somebody pointed a gun at me. 
(not if somebody would point)
•    If I didn't go to their party, they'd be upset.  (not If I wouldn't go)

But you can use if ... would when you ask somebody to do something:

•    (from a formal letter) I would be grateful if you would let me know your decision as soon as possible.

Unit 38; Part C

galka.jpgIn the other part of the sentence (not the if-part) we use would ('d) / wouldn't:

•   
If you took more exercise, you'd
(= you would) feel better.
•    I'm not tired. If I went to bed now, I wouldn't sleep.
•    Would you mind if I used your phone?

Could
and might are also possible:

•    If you took more exercise, you might feel better.  (= it is possible that you would feel better)
•    If it stopped raining, we could go out. 
(= we would be able to go out)

Unit 38; Part D

galka.jpgDo not use when in sentences like those on this page:

•   
They'd be upset if I didn't go to their party.
(not when I didn't go)
•    What would you do if you were bitten by a snake? 
(not when you were bitten)
