ACTIVE AND PASIVE SENTENCES, RELATIV CLAUSE,

in active voice when the subject of the sentence performs the action
in the sentence.

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.
Ø Defining relative clause
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.
In defining relative clauses we often use that instead
of who, whom orwhich. 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.
·
They should give the money to somebody who they think needs the treatment most.
Ø 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..
· Doctors use the
testing kit for regular screening for lung and stomach cancers, which
account for 70% of cancers treated in the western world.
·
Alice, who has worked in Brussels and London ever since
leaving Edinburgh, will be starting a teaching course in the autumn.
Conditional Sentences are also known
as Conditional Clauses or If Clauses. They are used to express that the action
in the main clause (without if) can only take place if a certain condition
(in the clause with if) is fulfilled. There are three types of Conditional
Sentences.
Ø Conditional Sentence Type 1
→ It is possible and also very
likely that the condition will be fulfilled.
Form :
if + Simple Present, will-Future
Example: If I find her address, I will
send her an invitation.
The main clause can also be at the beginning of the sentence. In this
case, don't use a comma.
Example: I
will send her an invitation if I find her address.
Note: Main clause and / or if clause might be negative. See Simple Present und will-Future on how to form negative sentences.
Example: If
I don’t see him this afternoon, I will phone him in the evening.
Use :
Conditional Sentences Type I refer to the future. An action in the future
will only happen if a certain condition is fulfilled by that time. We don't
know for sure whether the condition actually will be fulfilled or not, but the
conditions seems rather realistic – so we think it is likely to happen.
Example: If
I find her address, I’ll send her an invitation.
I want to send an invitation to a friend. I just have to find her
address. I am quite sure, however, that I will find it.
Example: If
John has the money, he will buy a Ferrari.
I know John very well and I know that he earns a lot of money and that he
loves Ferraris. So I think it is very likely that sooner or later he will have
the money to buy a Ferrari.
Example: If
I find her address, I’ll send her an invitation.
Ø Conditional Sentence Type II
→ It is possible but very
unlikely, that the condition will be fulfilled.
Form:
if + Simple Past, Conditional I (= would + Infinitive)
Example: If I found her address, I would send her an
invitation.
The main clause can also be at the
beginning of the sentence. In this case, don't use a comma.
Example: I would send her an invitation if I found her
address.
Note: Main clause and / or if
clause might be negative. See Simple Past und Conditional I on how to form negative sentences.
Example: If I had a lot of money, I wouldn’t stay
here.
Were instead of Was
In IF Clauses Type II, we usually use
‚were‘ – even if the pronoun
is I, he, she or it –.
Example: If I were you, I would not do this.
Use :
Conditional Sentences Type II refer
to situations in the present. An action could happen if the present situation
were different. I don't really expect the situation to change, however. I just
imagine „what would happen if …“
Example: If I found her address, I would send her an
invitation..
I would like to send an invitation to
a friend. I have looked everywhere for her address, but I cannot find it. So
now I think it is rather unlikely that I will eventually find her address.
Example: If John had the money, he would buy a
Ferrari.
I know John very well and I know that
he doesn't have much money, but he loves Ferraris. He would like to own a
Ferrari (in his dreams). But I think it is very unlikely that he will have the
money to buy one in the near future.
Ø Conditional Sentence Type 3
→ It is impossible that the
condition will be fulfilled because it refers to the past.
Form:
if + Past Perfect, Conditional II (= would + have + Past Participle)
Example: If I had found her address, I would have sent
her an invitation.
The main clause can also be at the
beginning of the sentence. In this case, don't use a comma.
Example: I would have sent her an invitation if I had
found her address
Note: Main clause and / or if
clause might be negative. See Past Perfect and Conditional II on how to form negative sentences.
Example: If I hadn’t studied, I
wouldn’t have passed my exams.
Use :
Conditional Sentences Type III refer
to situations in the past. An action could have happened in the past if a
certain condition had been fulfilled. Things were different then, however. We
just imagine, what would have happened if the situation had been fulfilled.
Example: If I had found her address, I would have sent
her an invitation.
Sometime in the past, I wanted to
send an invitation to a friend. I didn't find her address, however. So in the
end I didn't send her an invitation.
Example: If John had had the money, he would have
bought a Ferrari.
I knew John very well and I know that
he never had much money, but he loved Ferraris. He would have loved to own a
Ferrari, but he never had the money to buy one.
