Conditionals 1 A Conditions and results
Compare these sentences. The Vf...' clause is the condition, and the other part of the sentence is the result.
1 If sales increase (generally), we make more profit.
2 if sales increase (next quarter), we'll make more profit
3 If sales increased (next quarter), we'd make more profit.
4 If sales increased (last quarter), the Director should be happier
5 If sales had increased (last quarter), the Director would have been happier.
Sentence 1 is about something that is always true. See section B below.
Sentence 2 is about something that is reasonably likely to happen in the future. See section C.
Sentence 3 is about something that is imaginary or unlikely in the future, See section D.
■ Sentences 4 and 5 are about the past. See unit 18.
■ With all types of conditionals the If clause can come second. We'll make more profit if sales increase.
We'd make more profit if sales increased.

When we want to talk about things that are always or generally true, we use: If/When + present,   present simple or imperative

In the result clause there can be a present simple (last examples) or an imperative. When you fly business class, don't drink too much of the free alcohol.
Notice that we can use either if or when where the meaning is 'every time'.

present we use a present tense.

D If we sold.., (imaginary future)

,:: If we sold... (possible past)
When we want to talk about past events which possibly happened, we use lf + past simple in
the condition clause, and any tense or modal in the result clause.
If you went to the meeting yesterday, you probably heard the news.
If you missed the TV programme last night, you can borrow the recording I made.
3 If we had sold... (imaginary past)
When we want to talk about past events that are different to what really happened, we .use: lf + past perfect,   would + have + past participle
(condition) (result) If Clinton and Gore had won the election, they would have promoted free trade agreements with other nations in the same way as Bush. (Ynhoo Business News website)
There is often a suggestion of criticism or regret:
If the economic situation had been better, we wouldn't have lost so many customers.
A contracted'd in speech can be had in the condition or would in the result. If I'd done an MBA, I'd have had more opportunities.
The examples above are about two actions in the past. If the result clause refers to the present we use would + infinitive.
If I had done an MBA, I would be on a higher salaty now.
" Conditionals without if
We use if for something that might happen in the future, or something imaginary. We use
when for something that we know will happen.
I'll call you if I get a chance. (I'm not sure if I will phone you)
/'// call you when I arrive.     (I will definitely phone you)
We can use either if or when where the meaning is 'every time'.
If/When anyone rings my mobile, I get a photograph of the person on the screen.
In informal speech we sometimes use imagine or supposing in place of if. Imagine/Supposing you had a million dollars, how would you invest it?
We can use provided that, providing, on condition that, as long as and so long as for emphasis. The meaning is 'if and only if.
As long as there is new technology, consultants will continue to he in demand. (Sunday Times website)
We can use in case to talk about doing something to avoid a possible problem later. The result
clause usually comes first and often uses going to.
I'm going to give you my mobile number in case you need to contact me.
We use unless to mean If not.
D Wish
& We use / wish to express regret or dissatisfaction.
as For the present and future, use / wish followed by the past simple or continuous. / wish we didn't have so many meetings. I wish I wasn't working next weekend.
« For the past, use I wish followed by the past perfect. / wish we had advertised on television. I wish I hadn't eaten the oysters.
O If the wish is a good one, use / hope followed by the present simple or will. I hope your presentation goes well. I hope the merger will be a success.
o If the wish is about doing something that is difficult or impossible, use / wish I could. I wish I could contact him, but he hasn't got a mobile phone.
9 We can replace / wish with If only for emphasis. We stress only in speech. If only I hadn't eaten the oysters. If only I could contact him.
E Modal verbs in conditionals
The examples in unit 17 were with will. But other modal verbs like can, could, may, might, must and should are common in conditional sentences and have their normal meanings.
If you deal with the Middle East you must be available to your customers on Saturdays and Sundays. (Overseas Trade magazine)
If the euro were weak in the long term, companies might slow down their drive to increase productivity and governments might put the brake on their structural reforms. (Le Monde diplomatique website)
Compaq CEO Michael Capelias commented on the recent decline of dot.com firms, which were, so popular on the U.S. stock market a few months ago. If yon don't have a sound business plan, yon cannot succeed.' (International Herald Tribune website)
II We often use present forms like will and can with likely futures, and past forms like would Co) and could with imaginary futures
If you sign now, we'll/can deliver by Friday.        (likely future) If you signed now, we'd/could deliver by Friday, (imaginary future)
€1 But it is also common to find mixed tense sequences because modals keep their normal meanings:
If Hungarian farmers respond to competition by improving productivity and becoming more efficient at marketing, they could have a bigger share of the market. (Business Central Europe website)
With a present form (respond) we might expect can. However could is used here with its normal meaning of uncertainty (can does not express uncertainty).
t If I were you, ...
© We can use If 1 were in place of /// was in imaginary futures, particularly when we give advice with the phrase If I were you. If I were you, I'd wait until tomorrow. I'd be more careful, if I were you
