UNIT 7
THE COMPLEX SENTENCE
Subject, predicative, object and attributive clauses.
We often joint sentences by putting who or which (relative pronouns) in place of he, she, it or they. We use who for people and which for things.
I’ve got a friend. He collects stamps. – I’ve got a friend who collects stamps.
There’s a problem. It worries me. – There’s the problem which worries me.
Exercise 1. Join the sentences with who or which.
Beginnings
Ends
Do you know a shop?
He lives next door.
I know somebody.
He stole my car.
I want some plates.
She deals with exports.
I was at school with the man.
It isn’t working.
I’d like to speak to the person.
It needs to be eaten.

They last for years.
There’s some cheese in the fridge.
She could mend that chair.

They can go in the microwave.
This is the switch.
He is driving that taxi.
We often use that instead of which and instead of who in an informal style.
There’s a problem that you don’t understand.
I know some people that could help you.
Exercise 2. Rewrite four or more of the sentences from Exercise 1 using that.
In place of him, her, it and them (objects) we can use who(m), which or that.
Who is very informal as an object; whom is more formal.
Where’s that nurse? I saw her last time. – Where’s that nurse who(m)/that I saw last time?
These are problems. You don’t have them. – These are problems which/that you don’t have.
But we use which to refer to the whole clause. Compare:
The dentist pulled out the teeth which/that were causing trouble.
(‘Which/that’ just refers to ‘the teeth’.)
The dentist had to pull out two of my teeth, which was a real pity.
(‘Which refers to the whole clause before: ‘The dentist ... teeth’.)
Note that what cannot be used in this way.
He got the job, which surprised us all.

We normally use that, not which after all, everything, nothing, the only ... and superlatives.
