The Passive

We use the active form to say what the subject does. For example:

• I speak English every day at work.
• I repaired the flat tire on the car.

We use the passive form to say what happens to people and things, to say what is done to them. For example:

• English is spoken here.
• The car is being repaired.

We use the passive form when we don't know who did the action. For example:

• The car was damaged while it was parked on the street.
• The shirts were made in Turkey.

We use the passive to describe processes

• The data is fed into the computer.
• The bumpers are manufactured.

We use the passive form when what was done is more important than who did it. For example:

• It was approved by Gerry last week.
• I was informed by the Human Resources Manager only two days ago.

Comparatives and superlatives

We use Comparatives and Superlatives to compare two or more nouns.

The formation of the comparative and superlative depends on the number of syllables in the adjective:

One-syllable Adjectives

To form the comparative, we add -er to the end of the adjective.

To form the superlative, we add -est to the end of the adjective.

Adjective	Comparative	Superlative
small	smaller	the smallest
cold	colder	the coldest
light	lighter	the lightest
short	shorter	the shortest

Remember that comparatives are often followed by than.

• London is bigger than Santiago.
• Mike is taller than John but James is the tallest.

Two-syllable Adjectives ending in -Y

To form the comparative, we remove the -y and add -ier to the end of the adjective.

To form the superlative, we remove the -y and add -iest to the end of the adjective.

Adjective	Comparative	Superlative
crazy	crazier	the craziest
happy	happier	the happiest
early	earlier	the earliest

• It was the happiest day of my life.
• My joke was funnier than your one.

Adjectives with Two or more Syllables

For Adjectives with 2 syllables (that don't end in -y) and higher (3, 4 syllables etc), we use more for comparatives and the most for superlatives.

Adjective	Comparative	Superlative
handsome	more handsome	the most handsome
nervous	more nervous	the most nervous
enthusiastic	more enthusiastic	the most enthusiastic

• My girlfriend is more beautiful than yours.
• Alex is more intelligent than you but I am the most intelligent.

Irregular Forms

Adjective	Comparative	Superlative
good	better	the best
bad	worse	the worst
far	further / farther	the furthest / farthest

• I am a better tennis player than you but Marcelo is the best.
• Steve is a worse liar than me but Adrian is the worst.

Note: Further / farther, furthest / farthest are all used for distance.

Only Further / furthest are used to mean 'additional' or 'more advanced'.

• Ushuaia is further / farther than Barilocheis from here (in Buenos Aires).
• If you require further information, please contact reception.

Tag questions

We use tags in spoken English but not in formal written English.

They are not really questions but are a way of asking the other person to make a comment and so keep the conversation open.

Making a tag is very mechanical. To make a tag, use the first auxiliary. If there is no auxiliary, use do, does or did. With a positive sentence, make a negative tag and with a negative sentence, make a positive tag.

• It's beautiful, isn't it?
• He has been, hasn't he?
• You can, can't you?
• It must be, mustn't it?
• You know him, don’t you?
• He finished it, didn't he?
• He will come, won't he?

• It isn't very good, is it?
• It hasn't rained, has it?
• It can't be, can it?
• Jenny doesn't know James, does she?
• They didn't leave, did they?
• He won’t do it, will he?

Notice these:

• There isn't an ATM here, is there?
• Let's have a cup of coffee, shall we?

To reply, use the same auxiliary:

• It's beautiful, isn't it? ~ Yes, it is. I think it's fabulous.
• It isn't very good, is it? ~ No, it isn't. In fact, it's terrible.

Although, the rules are very simple and mechanical, in order to use them easily in conversation, they have to be automatic. So you need to hear and practice them very often.

Zero Conditional

When we talk about things that are generally or always true, we can use:

If/When/Unless plus a present form PLUS present simple or imperative

• If he gets there before me, ask him to wait.
• When you fly budget airline, you have to pay for your drinks and snacks.
• Unless you need more space, a small car is big enough for one person.

Note that we are not talking about a specific event but something which is generally true.

In the condition clause, we can use a variety of present forms. In the result clause, there can only be the present simple or imperative.

• If you visit London, go on the London Eye.
• If unemployment is rising, people tend to stay in their present jobs.
• If you've done that, go and have a coffee.
• When you go on holiday, take plenty of sun cream. It'll be very hot.
• When I'm concentrating, please don't make so much noise.
• When I've finished an article, I always ask Kate to read it through.

Notice that 'unless' means the same as 'if not'.

• Unless he asks you politely, refuse to do any more work on the project.
• Unless prices are rising, it's not a good investment.
• Unless you've been there yourself, you don't really understand how fantastic it is.

First Conditional

We use the First Conditional to talk about future events that are likely to happen.

• If we take John, he'll be really pleased.
• If you give me some money, I'll pay you back tomorrow.
• If they tell us they want it, we'll have to give it to them.
• If Mary comes, she'll want to drive.

The 'if' clause can be used with different present forms.

• If I go to New York again, I'll buy you a souvenir from the Empire State Building.
• If he's feeling better, he'll come.
• If she hasn't heard the bad news yet, I'll tell her.

The "future clause" can contain 'going to' or the future perfect as well as 'will'.

• If I see him, I'm going to tell him exactly how angry I am.
• If we don't get the contract, we'll have wasted a lot of time and money.

The "future clause" can also contain other modal verbs such as 'can' and 'must'.

• If you go to New York, you must have the cheesecake in Lindy's.
• If he comes, you can get a lift home with him.

Second Conditional

The Second Conditional is used to talk about 'impossible' situations.

• If we were in London today, we would be able to go to the concert in Hyde Park.
• If I had millions dollars, I'd give a lot to charity.
• If there were no hungry people in this world, it would be a much better place.
• If everyone had clean water to drink, there would be a lot less disease.

Note that after I / he/ she /it we often use the subjunctive form 'were' and not 'was'. (Some people think that 'were' is the only 'correct' form but other people think 'was' is equally 'correct' .)

• If she were happy in her job, she wouldn't be looking for another one.
• If I lived in Japan, I'd have sushi every day.
• If they were to enter our market, we'd have big problems.

Note the form 'If I were you' which is often used to give advice.

• If I were you, I'd look for a new place to live.
• If I were you, I'd go back to school and get more qualifications.

The Second Conditional is also used to talk about 'unlikely' situations.

• If I went to China, I'd visit the Great Wall.
• If I was the President, I'd reduce taxes.
• If you were in my position, you'd understand.

Note that the choice between the first and the second conditional is often a question of the speaker's attitude rather than of facts. Compare these examples. Otto thinks these things are possible, Peter doesn't.

• Otto – If I win the lottery, I'll buy a big house.
• Peter – If I won the lottery, I'd buy a big house.
• Otto – If I get promoted, I'll throw a big party.
• Peter – If I got promoted, I'd throw a big party.
• Otto – If my team win the Cup, I'll buy champagne for everybody.
• Peter – If my team won the Cup, I'd buy champagne for everybody.

Note that the 'If clause' can contain the past simple or the past continuous.

• If I was still working in Brighton, I would commute by train.
• If she were coming, she would be here by now.
• If they were thinking of selling, I would want to buy.

Note that the main clause can contain 'would' 'could' or 'might.

• If I had the chance to do it again, I would do it differently.
• If we met up for lunch, we could go to that new restaurant.
• If I spoke to him directly, I might be able to persuade him.

Also note that sometimes the 'if clause' is implied rather than spoken.

• What would I do without you? ("if you weren't here")
• Where would I get one at this time of night? ("if I wanted one")
• He wouldn't agree. ("if I asked him")

Third Conditional

We can use the Third Conditional to talk about 'impossible' conditions, impossible because they are in the past and we cannot change what has happened.

• If I had worked harder at school, I would have got better grades.
• If I had had time, I would have gone to see him. But I didn't have time.
• If we had bought that house, we would have had to rebuild the kitchen.
• If we had caught the earlier train, we would have got there on time but we were late.

Notice that the main clause can contain 'would', 'could' or 'might.

• If I had seen him at the meeting, I would have asked him. (But he wasn't there so I didn't.)
• If I had seen him at the meeting, I could have asked him. ( But he wasn't there so it wasn't possible.)
• If I had seen him at the meeting, I might have asked him. (But I'm not sure. Perhaps if the opportunity had arisen.)
• If I had paid more attention in class, I would have understood the lesson.

Also notice that sometimes the 'if clause' is implied rather than spoken.

• I'd have done it. ("if you had asked me but you didn't.")
• I wouldn't have said that. ("if I'd been there.")
• He wouldn't have let him get away with that. ("if he had tried that with me.")
