Conditional Sentences Exercises for Class 9 ICSE With Answers

Zero Conditional:
The zero conditional is a structure used for talking about general truths, things which always happen under certain conditions. This page will explain how the zero conditional is formed, and when to use it.

1. The structure of a zero conditional sentence
A zero conditional sentence consists of two clauses, an “if” clause and a main clause (In most zero conditional sentences you can use when or if and the meaning will stay the same.):
“if” clause main clause
If you heat water to 100 degrees, it boils.

If the “if” clause comes first, a comma is usually used. If the “if” clause comes second, there is no need for a comma:
main clause “if” clause
Water boils if you heat it to 100 degrees,

We use the same verb form in each part of a zero conditional: the simple present tense:
“if” clause main clause
if + subject + simple present verb subject + simple present verb

2. Using the zero conditional
The zero conditional is used to talk about things which are always true such as scientific facts and general truths:
Examples:

If you cross an international date line, the time changes.
If it rains, the grass gets wet.
Wood doesn’t burn if there is no air.

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

If we take Jyoti, she’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.

2. The ‘if clause can be used with different present forms.

If I go to Mumbai again, I’ll buy you a souvenir from the Gateway of India 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.

3. 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 at Lindy’s.
If he comes, you can get a lift home with him.

Second Conditional:
1. The Second Conditional is used to talk about hypothetical or unreal situations.

If we were in London today, we would be able to go to the concert in Hyde Park.
If I had million 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 diseases.
If I lived in Japan, I’d have sushi every day.
If they were to enter our market, we’d have big problems.

2. 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.

3. 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. Uma thinks these things are possible, Priti doesn’t.

Uma – If I win the lottery, I’ll buy a big house.
Priti – If I won the lottery, I’d buy a big house.
Uma – If I become the head girl, I’ll throw a big party.
Priti – If I got to be the head girl, I’d throw a big party.
Uma – If my team India wins the Cup, I’ll buy pizzas champagne for everybody.
Priti – If my team India won the Cup, I’d buy pizzas champagne for everybody.

4. Note that the ‘If clause’ can contain the past simple or the past continuous.

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

5. 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.

6. 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:
Third Conditional refer to situations in the past to express an action could have happened in the past if a certain condition had been fulfilled. It refers to hypothetical situations in the past. In this case we use the Past Perfect Tense in the clause and would + have in the main clause.

Example:

If I had found her address, I would have sent her an invitation.
If John had the money, he would have bought a Ferrari.

Mixed Conditional:

Those unreal conditional sentences whose time in the if clause is different from the time in the main clause. Mixed conditionals are formed when the present, the future or the past tense are used at the same time.
