Dialogue

1/Sentence Practice

This is the plane in which we came.

Can you imagine the air pressure at this altitude?

The instrument with which they measure air pressure is a barometer.

Torricelli, the Italian scientist on whose research was based the modern barometer, was a pioneer.

I know that air pressure decreases with altitude.

Fascinating, did you know that the plant from which this perfume is made is only grown in the Amazon rainforest?

I feel that we don’t always share the same interests. This is the reason we get on.

Imagine if I talked about football all the time. I don’t, that’s why we get along.

Two thousand and five was when I first traveled abroad. It was also the year in which we met each other.

University is the place where we met. We both got good marks which pleased our parents.

You were saying that this was the aircraft which we came in.

I suppose that it’s the same plane which comes from London and goes to Alicante each day.

I wonder if it is always with the same crews. I doubt it, it depends whose available on a certain date.

Grammar

Relative Pronouns

 

More terminology and examples

 

Defining and non defining relative clauses

 

Defining relative clauses

=

Clauses that contain key information. The information contained in the relative clause is essential and cannot be left out.

We can use “that” to introduce a defining relative clause, but also “who”, “which”, “whose”, “whom”.

This clause helps us define what we are talking about.

No commas are used in defining relative clauses.

 

Examples:

There the people who/that will be moving in next door.

You should give this to someone who/that is in need.

You will see some areas which/that have been affected.

They’re the patients that/who are showing the symptoms.




Non defining relative clauses

=

Clauses that describe or explain further but doesn’t contain key information.

Non-defining relative clauses are used to give further information about the person or thing mentioned in the main clause. It is not important information. We do not need it to understand whom or what is being referred to.

 

We always use a relative pronoun (who, which, whose or whom) to introduce a non-defining relative clause.

We don’t use “that” to introduce a non-defining relative clause.

In writing, we use commas around non-defining relative clauses.

In spoken English, we often pause at the beginning and end of the clause.

 

Examples:

Janet, who lives across the road, is originally from Kent.

His jacket, which is brown, is hanging in the hallway.

This place, which I had never never heard of before, is picturesque!
