10. We use relative clauses to give additional information about something without starting another sentence. By combining sentences with a relative clause, your text becomes more fluent and you can avoid repeating certain words.

How to Form Relative Clauses 

Imagine, a girl is talking to Tom. You want to know who she is and ask a friend whether he knows her. You could say:

A girl is talking to Tom. Do you know the girl?

That sounds rather complicated, doesn't it? It would be easier with a relative clause: you put both pieces of information into one sentence. Start with the most important thing  – you want to know who the girl is.

Do you know the girl …

As your friend cannot know which girl you are talking about, you need to put in the additional information  – the girl is talking to Tom. Use „the girl“ only in the first part of the sentence, in the second part replace it with the relative pronoun (for people, use the relative pronoun „who“). So the final sentence is:

Do you know the girl who is talking to Tom?

Subject Pronoun or Object Pronoun?

Subject and object pronouns cannot be distinguished by their forms - who, which, that are used for subject and object pronouns. You can, however, distinguish them as follows:

If the relative pronoun is followed by a verb, the relative pronoun is a subject pronoun. Subject pronouns must always be used.

the apple which is lying on the table

If the relative pronoun is not followed by a verb (but by a noun or pronoun), the relative pronoun is an object pronoun. Object pronouns can be dropped in defining relative clauses, which are then called Contact Clauses.

the apple (which) George lay on the table

11. We use 'used to' for something that happened regularly in the past but no longer happens.

• I used to smoke a packet a day but I stopped two years ago.

• Ben used to travel a lot in his job but now, since his promotion, he doesn't.

• I used to drive to work but now I take the bus.

We also use it for something that was true but  no longer is.

• There used to be a cinema in the town but now there isn't.

• She used to have really long hair but she's had it all cut off.

• I didn't use to like him but now I do.

'Used to do' is different from 'to be used to doing' and 'to get used to doing'

to be used to doing

We use 'to be used to doing' to say that something is normal, not unusual.

• I'm used to living on my own. I've done it for quite a long time.

• Hans has lived in England for over a year so he is used to driving on the left now.

• They've always lived in hot countries so they aren't used to the cold weather here.

to get used to doing

We use 'to get used to doing' to talk about the process of something becoming normal for us.

• I didn't understand the accent when I first moved here but I quickly got used to it.

• She has started working nights and is still getting used to sleeping during the day.

• I have always lived in the country but now I'm beginning to get used to living in the city.

12. Use of Passive

Passive voice is used when the focus is on the action. It is not important or not known, however, who or what is performing the action.

Example: My bike was stolen.

In the example above, the focus is on the fact that my bike was stolen. I do not know, however, who did it.

Sometimes a statement in passive is more polite than active voice, as the following example shows:

Example: A mistake was made.

In this case, I focus on the fact that a mistake was made, but I do not blame anyone (e.g. You have made a mistake.).

Form of Passive

Subject + finite form of to be + Past Participle (3rd column of irregular verbs)

Example: A letter was written.

When rewriting active sentences in passive voice, note the following:

• the object of the active sentence becomes the subject of the passive sentence

• the finite form of the verb is changed (to be + past participle)

• the subject of the active sentence becomes the object of the passive sentence (or is dropped)

13. Simple Future has two different forms in English: "will" and "be going to." Although the two forms can sometimes be used interchangeably, they often express two very different meanings. These different meanings might seem too abstract at first, but with time and practice, the differences will become clear. Both "will" and "be going to" refer to a specific time in the future.

"Will" often suggests that a speaker will do something voluntarily. A voluntary action is one the speaker offers to do for someone else. Often, we use "will" to respond to someone else's complaint or request for help. We also use "will" when we request that someone help us or volunteer to do something for us. Similarly, we use "will not" or "won't" when we refuse to voluntarily do something.

“Be going to” is usually used when something is already planned or definite. Look at the difference between these sentences:

I'll make the supper tonight. (Making a decision/volunteering to do something.) I'm going to make the supper every Wednesday. (This is already planned and organized.)

14.

If we report what another person has said, we usually do not use the speaker’s exact words (direct speech), but reported (indirect) speech. Therefore, you need to learn how to transform direct speech into reported speech. The structure is a little different depending on whether you want to transform a statement, question or request.

Statements

When transforming statements, check whether you have to change:

• pronouns

• present tense verbs (3rd person singular)

• place and time expressions

• tenses (backshift)

Type	Example
direct speech	“I speak English.”
reported speech (no backshift)	He says that he speaks English.
reported speech (backshift)	He said that he spoke English.
