If the weather is nice, we'll go swimming.

If you have finished your coffee, we can pay the bill.

If you're ill, see a doctor! If you burn yourself, it hurts.

Type 2 unreal present

(but I don't have money - untrue in the present)

If we hadn't left so early, we would have missed the plane.

If youhad told me before about your problems, I would have helped you , but now it’s too late.

If the weather hadn’t been so nasty yesterday, we would not have stayed at home all day long.

 

Expressions

 

Conditionals are usually introduced by IF; the following expressions can be uses in stead of IF: providing,  provided (that), as long as, in case, on condition (that), but for (=without), otherwise, or else, what if, supposing, even if, only if, unless.  

 

2.1 If only: This adds emphasis to hypothetical situations. With past events it adds a sense of regret. The second part of the sentence is often left out.

If only I had enough time!

If only I hadn 't drunk too much, this wouldn 't have happened!

 

2.2 Unless and other alternatives

Unless only if not. Not all negative IF-sentences can be transformed into unless sentences.

If he wasn 't told by Jane, he couldn 't have known.

Unless he was told by Jane, he couldn 't have known, (can be changed)

If Mr Smith doesn 't come back, he 'II phone you. (cannot be changed)

If one situation depends on another, it can be replaced by as/so long as, provided or only if.

 

2.3 Only if combines with other time expressions and is used with past simple

Only after posting the letter did I remember that I had forgotten to put on a stamp.  (inversion)

I'll do what you say provided the police are not informed.

 

2.4 Even if describes how something will happen whatever the condition.

Even if it rains, we'll still go for a picnic.

 

2.5 But for him, I wouldn’t have been able to survive. (If he hadn’t helped me…)

 

2.6 Supposing it rains, will you still go for a picnic?

 

2.7 What if it rains,  will you go for a walk?

 

2.8 We  can omit “if”, when should, were and had come before the subject.

 Should, come, tell him to wait for me.

Were you, I would speak to her.  known, he would have told us. 

 

4. Other tenses in conditional sentences

 

4.1 Going to  Going to can replace will.

If you fall, you 're going to hurt yourself.

If you 're going to make trouble, we 'II call the police.

 

4.2 Present perfect This can be used to emphasis completion after if.

If you've finished, then we'll go. It is also possible in both parts of the sentence.

If I've told you once, I've told you a hundred times!

 

4.3 Doubt and uncertainty

An additional not can be added in formal expressions involving doubt. This emphasizes the uncertainty and does not add a negative meaning.

I wouldn 't be surprised if it didn 't rain. (I think it will rain.)

 

4.4 Should

if, this makes the possibility of an event seem unlikely.

If you should see Ann, could you ask her to call me?

This implies that I do not expect you to see Ann.

 

4.5 Were to  This also makes an event seem more hypothetical.

If I were to ask you to marry me, what would you say?

 

4.6 Happen to

This emphasizes chance possibilities. It is often used with should.

If you happen to see Helen, could you ask her to call me?

If you should happen to be passing, drop in for a cup of tea.

 

4.7 If it were not for/If it hadn 't been for

This describes how one event depends on another.

If it weren 't for Jim, this company would be in a mess.

If it hadn't been for their goalkeeper, United would have lost.

 

4.8 Will and would: politeness and emphasis These can be used as polite forms.

If you will/would wait here, I'll see if Mrs Green is free.

Will can also be used for emphasis, meaning 'insist on doing'.

If you will stay out late, no wonder you are tired! (insist on staying)

4.9 If and adjectives

In expressions such as if it is necessary/possible it is possible to omit the verb be. If interested, apply within. If necessary, take a taxi.

 

4.10 Formally if can mean although, usually as if + adjective.

The room was well-furnished, if a little badly decorated.

 

5.1 Subjunctive sentences: SUBJECT + VERB + THAT + SUBJECT + INF. without to

  John's mother insisted that he return home early.

 

5.2.Subjunctive обозначает особую группу глагольных временных форм (типа pres. — bepast — wereforallpersons — для глагола tobe или infinitivewithoutto — для других глаголов), используемых для описания событий, которые вряд ли когда-либо будут иметь место, но которые являются предметом наших надежд, мечтаний, желаний.

 

5.3 The Present Subjunctive

 

The Present Subjunctive is used after

Verbs

Impersonal expressions

Indicating that one person wants another one to do something   

Advise, order, demand, ask, require, recommend, command, propose, insist, suggest

It is  necessary, important, proposed, recommended, suggested

He suggested that she go there. He suggested that they should go there.

It is suggested that she go there

 

5.4 Note the difference:

 

British variant:  I insist that you should leave without her.

   It is recommended that you should publish your book.

American variant:   I insist that you leave without her.

   It is recommended that you publish your book

 

5.5 The Past Subjunctive prefers to use were instead of was.

She behaves as if she were / was a queen.

I wish it were true

 

6. Present and past reference with 'I wish', 'if only' and 'it's (high) time'

 

(I) wish, if only. it's (high) time and it's (about) time, we 'go one tense back':

1 The past tense refers to the present:I wish I had a better watch! (NOW)

2 The past perfect tense refers to the past:If only you had asked me first! (THEN)

 

7. Expressing wishes and regrets with 'I wish' and 'if only

7.1 We often use I wish for things that might (still) happen:

 

I wish I knew the answer! (= it's possible I might find out the answer)

If only is stronger. We use it to express regret for things that can (now) never happen:

If only your mother were alive now! (Of course, / wish is also possible.)

 

7.2 We may use the simple past of be after wish and if only

 

I wish I was on holiday now. If only Tessa was here now!

If we want to be more formal, we use were in all persons

I wish I were on holiday now. If only Tessa were here!

 

7.3 We may use the past perfect of be for things that can never happen:

 

I wish I had been on holiday last week. If only Tessa had been here yesterday!

 

7.4 We use the past or past perfect forms of other verbs:

I wish I knew the answer to your question.

I wish I had known then what I know now!

 

8. 'Would' and 'could' after 'I wish' and 'if only'

 

We must use could, not would, after /and we. Compare:

I can't swim.                           →        wish I could swim.

We weren't together!              →        I wish we could have been together

We sometimes use / wish you (he. she. etc.)would(n't) like an imperative:

(I am making a lot of noise!)  →   I wish you wouldn't make so much noise!

(He is making a lot of noise!)  →       I  wish he would be quiet!

 

9. 'It's (high) time' and 'It's (about) time'

We use It's time, It's high time and it’s about time to express present or future wishes, or to express our impatience about things that haven't happened yet:

Kim can't even boil an egg. - I know.

It's time/high time/about time she learnt to cook!

 

10. Expressing personal preference with 'I'd rather/ I'd sooner'

 

We use would rather and would sooner to express preference.

We can refer to the present or the future:

I'd rather/I'd sooner be a builder than an architect.

Or we can refer to the past:

If I could choose again, I'd rather/sooner have been a builder than an architect.

11. Expressing preferences about other people's actions

 

11.1 We can refer to other people after I'd rather or I'd sooner.

 

I'd rather leave on an earlier train. (= I'm referring to myself)

I'd rather Jackleft on an earlier train. ( I want him to leave)

 

11.2 We use the past tense form after I'd rather to refer to the present or future.

 

I'd rather be happy. I'd rather not sit next to her. (= for myself)

I'd rather she were/was happy. (= now)

I'd rather she didn't sit next to me. (= now)

 

11.3 We use the past perfect form after I'd rather to refer to past time.

 

I'd rather have been present. (= then - I'm referring to myself)

I'd rather you had been present, (then)

I'd rather you hadn't told me about it. (then)

 

12. 'I'd rather he didn't'

 

We generally omit the main part of the verb in short responses:

 

12.1 negative responses:    

Frank is going to buy a motorbike. - I'd rather he didn't.

I′ve told everyone about it.   - I'd rather you hadn't.

 

12.2 affirmative responses:

Frank won't give up his present job. - I'd rather he did.

I haven't told anyone about it. - I'd rather you had.

 

12.3 We do not have to repeat the main verb in a complete sentence:

You always go without me and I'd rather you didn't.

Radar

On May 7th, 1915, during the First World War (1914-1918), a large British passenger ship, the Lusitania, was sailing in perfect weather from America to England, with two thousand people on board. Suddenly, at about half past two in the afternoon, there were two fearful explosions. The ship shook from end to end, and many people were thrown off their feet. A German submarine had fired at the Lusitania and blown two holes in her bottom. The sea rushed into her engine-rooms, and almost immediately the ship began to sink.

She sank in only twenty minutes; and nearly one thousand people lost their lives.

The captain could not see the submarine that attacked his ship, and he had no instrument to show him the danger. Now the danger of surprise attacks against ships and collisions with icebergs is greatly reduced by radar. This radio instrument finds the position and distance of objects which the human eye may not be able to see; it also records the direction and speed of moving objects, such as ships and aeroplanes. Radar can pick out objects more than a hundred miles away in the worst weather conditions, when we can see perhaps no farther than a hundred yards.

Radar works in this way. Powerful transmitters send out a stream of radio-waves, called "pulses", at the rate of perhaps one thousand every second. These pulses shoot through the air at a speed of one hundred and eighty-six thousand miles a second till they hit an object, perhaps a ship, an aeroplane, an iceberg or a hill. These pulses cannot go through the object; and so they immediately shoot back at the same speed, in the opposite direction, and hit the aerial of the radar. The moment this happens, a spot or line of light appears on the radar screen, showing the position and distance of the object.

Today radar is used for many peaceful purposes all over the world. Modern ships of all nations carry radar to help them sail in bad weather, when it is possible to see for a distance of perhaps only a few hundred yards. In the past, the captain usually had to anchor his ship at such times and wait for conditions to improve. But today a ship with radar can sail in almost any weather conditions, with no danger of an accident.

Radar also helps to guide aeroplanes across the world. Radio signals called beams are transmitted into the sky from land radio stations at a number of points along their course. The pilots can hear these signals on their radio and see them on their radar screen. The beams arg like sign-posts in the sky. A pilot guides his aeroplane towards one beam, and then flies on to the next beam. At the end of his journey, he will land his aeroplane with the help of radar.

Trained men at the airport watch the aeroplane on their radar screen and tell the pilot by radio the course to follow, they tell him when and by how much to reduce height, and give any other orders that may be necessary.
