DEFINING RELATIVE CLAUSES

Defining Relative Clauses 

Defining relative clauses (also called identifying relative clauses or restrictive relative clauses) give detailed information defining a general term or expression. Defining relative clauses are not put in commas.

Imagine, Tom is in a room with five girls. One girl is talking to Tom and you ask somebody whether he knows this girl. Here the relative clause defines which of the five girls you mean.

Do you know the girl who is talking to Tom?

Defining relative clauses are often used in definitions.

A seaman is someone who works on a ship.

Object pronouns in defining relative clauses can be dropped. (Sentences with a relative clause without the relative pronoun are called Contact Clauses.)

The boy (who/whom) we met yesterday is very nice.

Non-Defining Relative Clauses 

Non-defining relative clauses (also called non-identifying relative clauses or non-restrictive relative clauses) give additional information on something, but do not define it. Non-defining relative clauses are put incommas.

Imagine, Tom is in a room with only one girl. The two are talking to each other and you ask somebody whether he knows this girl. Here the relative clause is non-defining because in this situation it is obvious which girl you mean.

Do you know the girl, who is talking to Tom?

Note: In non-defining relative clauses, who/which may not be replaced with that.

Object pronouns in non-defining relative clauses must be used.

Jim, who/whom we met yesterday, is very nice.

How to Shorten Relative Clauses? 

Relative clauses with who, which, that as subject pronoun can be replaced with a participle. This makes the sentence shorter and easier to understand.

I told you about the woman who lives next door. – I told you about the woman living next door.

Do you see the cat which is lying on the roof? – Do you see the cat lying on the roof?

PRESENT SIMPLE

Simple present is also called present simple.

The simple present expresses an action in the present taking place once, never or several times. It is also used for actions that take place one after another and for actions that are set by a timetable or schedule. The simple present also expresses facts in the present.

All other verbs

Use:

• the infinite verb (play) with the personal pronouns I, you, we and they (or with the plural form of nouns)
• the verb + s (plays) with the personal pronouns he, she, it (or with the singular form of nouns)

	affirmative	negative	question
I/you/we/they	I play.	I do not play.	Do I play?
he/she/it	He plays.	He does not play.	Does he play?

Tips on how to form negative sentences and questions

Negative sentences and questions are formed with the auxiliary verb 'do'.

 Animation on negative sentences and questions

The 3rd person singular of 'do' is 'does'. This means that in negative sentences and questions the 's' of the main verb is placed behind 'do'.

have

Use:

• have with the personal pronouns I, you, we und they (or with the plural form of nouns)
• has with the personal pronouns he, she, it (or with the singular form of nouns)

example: I have a dog. / I have got a dog.

'have got' is mainly used in British English. You can also use 'have' on its own (especially in American English). In this case, however, you must form negative sentences and questions with the auxiliary verb 'do' (see 'All other verbs').

	positiv	negativ	question
I/you/we/they	I have got. / I have.	I have not got. / I do not have.	Have I got? / Do I have?
he/she/it	He has got. / He has.	He has not got. / He does not have.	Has he got? / Does he have?

Use

Both tenses are used to express that an action began in the past and is still going on or has just finished. In many cases, both forms are correct, but there is often a difference in meaning: We use the Present Perfect Simple mainly to express that an action is completed or to emphasise the result. We use the Present Perfect Progressive to emphasise the duration or continuous course of an action.

Result or duration?

Do you want to express what has happened so far or how long an action has been going on yet?

Present Perfect Simple	Present Perfect Progressive
Result (what / how much / how often) I have written 5 letters. / I have been to London twice.	Duration (how long) I have been writing for an hour.

Certain verbs

The following verbs are usually only used in Present Perfect Simple (not in the progressive form).

• state: be, have (for possession only)
  Example: We have been on holiday for two weeks.
• senses: feel, hear, see, smell, taste, touch
  Example: He has touched the painting.
• brain work: believe, know, think, understand
  Example: I have known him for 3 years.

Emphasis on completion or duration?

Do you want to emphasise the completion of an action or its continuous course (how has somebody spent his time)?

Present Perfect Simple	Present Perfect Progressive
Emphasis on completion I have done my homework. (Meaning: My homework is completed now.)	Emphasis on duration I have been doing my homework. (Meaning: That's how I have spent my time. It does not matter whether the homework is completed now.)

Result or side effect?

Do you want to express that a completed action led to a desired result or that the action had an unwanted side effect?

Present Perfect Simple	Present Perfect Progressive
desired result I have washed the car. (Result: The car is clean now.)	unwanted side effect Why are you so wet? - I have been washing the car. (side effect: I became wet when I was washing the car. It does not matter whether the car is clean now.)

Time + negation: last time or beginning of an action?

In negative sentences: Do you want to express how much time has past since the last time the action took place or since the beginning of the action?

Present Perfect Simple	Present Perfect Progressive
since the last time I haven't played that game for years. (Meaning: It's years ago that I last played that game.)	since the beginning I haven't been playing that game for an hour, only for 10 minutes. (Meaning: It's not even an hour ago that I started to play that game.)

Permanent or temporary?

If an action is still going on and we want to express that it is a permanent situation, we would usually use the Present Perfect Simple. For temporary situations, we would prefer the Present Perfect Progressive. This is not a rule, however, only a tendency.

Present Perfect Simple	Present Perfect Progressive
permanent James has lived in this town for 10 years. (Meaning: He is a permanent resident of this town.)	temporary James has been living here for a year. (Meaning: This situation is only temporary. Maybe he is an exchange student and only here for one or two years.)

Use

In British English, the use of Simple Past and Present Perfect is quite strict. As soon as a time expression in the past is given, you have to use Simple Past. If there are no signal words, you must decide if we just talk about an action in the past or if its consequence in the present is important.

Note that the following explanations and exercises refer to British English only. In American English, you can normally use Simple Past instead of Present Perfect. We cannot accept this in our exercises, however, as this would lead to confusions amongst those who have to learn the differences.

Certain time in the past or just / already / yet?

Do you want to express that an action happened at a certain time in the past (even if it was just a few seconds ago) or that an action has just / already / not yet happened?

Simple Past	Present Perfect Simple
certain time in the past Example: I phoned Mary 2 minutes ago.	just / already / not yet Example: I have just phoned Mary.

Certain event in the past or how often so far?

Do you want to express when a certain action took place or whether / how often an action has happened till now?

Simple Past	Present Perfect Simple
certain event in the past Example: He went to Canada last summer.	whether / how often till now Example: Have you ever been to Canada? / I have been to Canada twice.

Emphasis on action or result?

Do you just want to express what happened in the past? Or do you want to emphasise the result (a past action's consequence in the present)?

Simple Past	Present Perfect Simple
Emphasis on action Example: I bought a new bike.(just telling what I did in the past.)	Emphasis on result Example: I have bought a new bike. (With this sentence I actually want to express that I have a new bike now.)
