1. Active and passive sentences
a. Active sentences
In active sentences, the thing doing the action is the
subject of the sentence and the thing receiving the action is the object. Most
sentences are active. In
most English sentences with an action verb, the subject performs the action
denoted by the verb.
[Thing doing action] + [verb] + [thing receiving
action]
b. Passive sentences
In passive
sentences, the thing receiving the action is the subject of the sentence and
the thing doing the action is optionally included near the end of the sentence.
You can use the passive form if you think that the thing receiving the action
is more important or should be emphasized. You can also use the passive form if
you do not know who is doing the action or if you do not want to mention who is
doing the action. One can change the normal word order of many active sentences
(those with a direct object) so that the subject is no longer active, but is, instead, being acted
upon by the verb – or passive.
[Thing
receiving action] + [be] + [past participle of verb] + [by] + [thing doing
action]
Example :
1. Active : The Instructor chose the squirrels’ lab partners.
Passive : The squirrels’ lab partners were chosen by the
instructor.
2. Active : At each concert,
the soprano sang at least one tune from a well-known opera.
Passive : At each concert, at least one tune from a well-known
opera was sung by the soprano.
3. Active : The
hunter killed the lion.
Passive : The lion was killed by the hunter.
4. Active :
Someone has cleaned the windows.
Passive : The windows have been cleaned.
5. Active : I gave him a
book for his birthday.
Passive : He
was given a book for his birthday.

Relative Clauses
Relative clauses are clauses starting with the
relative pronouns who*, that, which, whose, where, when. They are
most often used to define or identify the noun that precedes them. Here are
some examples:
- Do you know the girl who started
in grade 7 last week?
- Can I have the pencil that I
gave you this morning?
- A notebook is a computer which can
be carried around.
- I won't eat in a restaurant whose cooks
smoke.
- I want to live in a place where there
is lots to do.
- Yesterday was a day when everything
went wrong!
As the name
suggests, defining relative clauses give essential information to define or
identify the person or thing we are talking about. Take for example the
sentence: Dogs that like cats are
very unusual. In
this sentence we understand that there are many dogs in the world, but we are
only talking about the ones that like cats. The defining relative clause gives
us that information. If the defining relative clause were removed from the
sentence, the sentence would still be gramatically correct, but its meaning
would have changed significantly.
Defining relative clauses are composed of a relative pronoun
(sometimes omitted), a verb, and optional other elements such as the subject or
object of the verb. Commas are not used to separate defining relative clauses
from the rest of the sentence. Commas or parentheses are used to separate
non-defining relative clauses from the rest of the sentence.
EXAMPLES
- Children who
hate chocolate are
uncommon.
- They live
in a house whose roof is full of holes.
- An elephant
is an animal that lives in hot countries.
- Let's go to
a country where the sun always shines.
- The reason why
I came here today is
not important.
RELATIVE PRONOUNS
The following relative pronouns are used in defining relative
clauses. These relative pronouns appear at the start of the defining relative
clause and refer to a noun that appears earlier in the sentence.

REPLACING WITH "THAT" IN
SPOKEN ENGLISH
The pronouns who, whom, and which are often replaced by that in spoken English. Whom is very formal and is
only used in written English. You can use who or that instead, or omit the
pronoun completely. In the examples below, the common usage is given with the
defining relative clause highlighted. The pronoun that would be used in more
formal written English instead of that is given in
parentheses.
EXAMPLES
- The dish that
I ordered was
delicious. (which)
- The man that
came with her has
already left. (who)
- The doctor that
I was hoping to see wasn't
on duty. (whom)
INCLUDING OR OMITTING THE RELATIVE
PRONOUN
The relative pronoun can only be omitted when it is the object of the clause. When
the relative pronoun is the subject of the clause, it
cannot be omitted. You can usually tell when a relative pronoun is the object
of the clause because it is followed by another subject + verb. See below, in
the first sentence the relative pronoun cannot be ommitted because it is the
subject of the relative clause ("the woman spoke"). In the second
sentence, the pronoun can be omitted because "the woman" is the
object of the verb "loved".

subject of the main clause
|

Verb

|

|
The

|
spoke
at the meeting
|
was
very knowledgeable.
|
The
woman
|
(that)
|
the
man loved
|
was
living in New York.
|
OTHER USES OF "THAT"
'That' is often used to introduce defining relative clauses
when they follow the words something, anything, everything, nothing,
all or
a superlative. It may be omitted when it is not the subject of the clause.
EXAMPLES
- There's
something (that) you should know.
- It was the
best film (that) I've ever seen.
- Do you have
anything that will help my throat?
- Everything (that)
you say seems silly
to me.
- Nothing (that)
anyone does can
replace my lost bag.
- I'm sorry,
but that is all (that) I saw.

Conditional Sentences
Conditional
tenses are used to speculate about what could happen, what might have happened,
and what we wish would happen. In English, most sentences using the conditional
contain the word if. Many conditional forms in English are used in
sentences that include verbs in one of the past tenses. This usage is referred
to as "the unreal past" because we
use a past tense but we are not actually referring to something that happened
in the past. There are five main ways of constructing conditional sentences in
English. In all cases, these sentences are made up of an if clause
and a main clause. In many negative conditional sentences, there is an
equivalent sentence construction using "unless" instead of
"if".

A. THE ZERO
CONDITIONAL
The zero
conditional is used for when the time being referred to is now or
always and the situation is real and possible. The zero
conditional is often used to refer to general truths. The tense in both parts
of the sentence is the simple present. In zero conditional sentences, the word
"if" can usually be replaced by the word "when" without
changing the meaning.

|
B. TYPE 1
CONDITIONAL
§
The type 1
conditional is used to refer to the present or future where
the situation is real. The type 1 conditional refers to a possible
condition and its probable result. In these sentences the if clause is in the
simple present, and the main clause is in the simple future.

|
If this thing happened
|

If you went to bed earlier
|
you would not be so tired.
|
If it rained
|
you would get wet.
|
If I spoke Italian
|
I would be working in Italy.
|
The type 2 conditional is used to refer to a time that is now or any time, and a situation that is unreal. These sentences are not based on fact. The type 2 conditional is used to refer to a hypothetical condition and its probable result. In type 2 conditional sentences, the if clause uses the simple past, and the main clause uses the present conditional.
D. TYPE 3
CONDITIONAL
The type 3
conditional is used to refer to a time that is in the past, and a
situation that is contrary to reality. The facts they are based on
are the opposite of what is expressed. The type 3 conditional is used to refer
to an unreal past condition and its probable past result. In type 3 conditional
sentences, the if clause uses the past perfect, and the main clause uses the
perfect conditional.
If clause

|

|
I would have a better job now.
|
If we had looked at the map
|
we wouldn't be lost.
|
If you weren't afraid of spiders
|
you would have picked it up and
put it outside.
|
The mixed type conditional is used to refer to a time that is in the past, and a situation that is ongoing into the present. The facts they are based on are the opposite of what isexpressed. The mixed type conditional is used to refer to an unreal past condition and its probable result in the present. In mixed type conditional sentences, the if clause uses the past perfect, and the main clause uses the present conditional.
