See Irregular Verbs for a list of present, past and past participle forms of irregular verbs.Affirmative Form | Subject + have / has + verb3 + complement She has found her book. |
Negative Form | Subject + haven't / hasn't + verb3 + complement She hasn't found her book. |
Question Form | Have / Has + subject + verb3 + complement ? Has she found her book? |
Negative Question | Haven't / Hasn't + subject + verb3 + complement ? Hasn't she found her book? |

PASSIVE TENSE
VERB TO BE + PAST PARTICIPLE
When we say what people do, we use ACTIVE VERBS .
Eg. I buid, I speak, etc.
When we say what happens to people or things ( what is done to them) we use the PASSIVE.
The OBJECT of an ACTIVE VERB corresponds to the SUBJECT of the PASSIVE verb.
ACTIVE A does B
PASSIVE B is done (by) A
Use of Passive Voice

We use gerunds (verb + ing):

We use 'to' + infinitive:
- After certain verbs - We decided to leave
- After many adjectives - It's difficult to get up early
- - I came to London to study English
We use the bare infinitive (the infinitive without 'to'):
- After modal verbs - I can meet you at six o'clock
- After 'let', 'make' and (sometimes) 'help' - The teacher let us leave early
- After some verbs of perception (see, watch, hear, notice, feel, sense) - I watched her walk away

Defining relative clauses
We use defining relative clauses to give essential information about someone or something – information that we need in order to understand what or who is being referred to. A defining relative clause usually comes immediately after the noun it describes.
We usually use a relative pronoun (e.g. who, that, which, whose and whom) to introduce a defining relative clause (In the examples, the relative clause is in bold, and the person or thing being referred to is underlined.):
They’re the people who want to buy our house.
Here are some cells which have been affected.
They should give the money to somebody who they think needs the treatment most.
[talking about an actress]
She’s now playing a woman whose son was killed in the First World War.
In defining relative clauses we often use that instead of who, whom or which. This is very common in informal speaking:
They’re the people that want to buy our house.
Here are some cells that have been affected.
Non-defining relative clauses
We use non-defining relative clauses to give extra information about the person or thing. It is not necessary information. We don’t need it to understand who or what is being referred to.
We always use a relative pronoun (who, which, whose or whom) to introduce a non-defining relative clause (In the examples, the relative clause is in bold, and the person or thing being referred to is underlined.)
Clare, who I work with, is doing the London marathon this year.
Not: Clare, I work with, is doing the London marathon this year.
Alice, who has worked in Brussels and London ever since leaving Edinburgh, will be starting a teaching course in the autumn.
