CBSE Book Class 10 English Conditionals

A. Introduction

Read the following sentences:

1. I'll help you if you promise to work hard.

2. If I had the money, I would lend it to you.

3. If we had practised well, we could have won the match.

4. Most dogs snarl if you pull their tail.

• You notice that all the above sentences have two parts - a main clause and a subordinate clause. Main Clause Subordinate Clause

• All the subordinate clauses in the above sentences begin with 'if'.

• Both the clauses express conditions, i.e., one event follows from the other, or depends on the other. In other words, what we express in the main clause. depends - or is conditional - on what we express in the subordinate (if) clause

• We can usually change the order of clauses in conditional sentences. eg. we can say: I'll help you if you promise to work hard. We can also say: If you promise to work hard, I'll help you.

• In general we separate the two clauses by a comma if we begin with an 'if' clause. We don't use a comma when we begin with the main clause.
