The conditional sentences in English language sentence

CONDITIONAL SENTENCES (If clause)
These are kinds of sentences which require a certain condition / situation to be fulfilled before a certain action could take place.
These are sentences that give conditions
Therefore any conditional sentence has two main parts. The –if clause and the main clause.
Example; in the sentence        “If he comes, I will go out”
                                    “If he comes” is the if-clause and “I will go out” is the main clause.
A.     AN IF CLAUSE       (dependent clause)
This contains a condition and it depends on the main clause to fulfill its meaning.
The If clause is the subordinate i.e. it cannot stand by itself because it does not express complete thoughts. It is sometimes known as dependent clause.
Example
i)                    If John comes ……………………
ii)                  If I work hard …………………….
iii)                If you study hard ………………….
iv)                If I were God ……………………
v)                  If I know them …………………..
vi)                If I find a house ………………….
vii)              If I were you ……………………..
EXERCISE
Complete the following type 1 conditional sentences by using the words of your own choice and the words given in the brackets.
1.      If he comes late to school, he …………….. (punish)
2.      If she gets a pen, she …………. (write) a letter.
3.      If the driver drives carefully, the traffic officer ………. (not stop) him.
4.      My parents …………….. (not praise) me if I become the last in class.
5.      If Asha sells her car, she ………… (get) ………….

13.  I ……………… (see) if I go to his house.
14.  If he buys a dictionary, he …………… (use) ………
15.  If I get money, I ………….. (buy) …………
These sentences are called if clause in conditional sentences because they contain IF at the beginning of their sentences.

B.     THE MAIN CLAUSE (independent clause)
This has complete meaning, it does not depend on other clauses to fulfill the meaning. It can stand by itself as a sentence.
Examples
i)                    I will tell my friend.
ii)                  I shall enjoy myself.
iii)                My parents will be happy.
iv)                He will marry my young sister.
v)                  I will give the money for him.
vi)                She will marry my young brother.



TYPES OF CONDITIONAL SENTENCES
There are three types of conditional sentences in English. Each kind contains a different pair of tenses.
1.      Conditional type 1.
2.      Conditional type 2.
3.      Conditional type 3.

CONDITIONAL TYPE 1 SENTENCE
It is also called open condition. It expresses likely condition.
It tells us something will take place, if a certain condition fulfilled. This condition may or may not be fulfilled. This means that the action in the main clause in type 1 is likely to happen only if the condition in the if-clause is fulfilled.
Example;
i)                    If she buys a pen, she will write a letter.
ii)                  If they get money, they will buy a new bus.
iii)                If she comes here, I will tell her a story.
Note:
(i)                 It doesn’t matter which part of the two comes first.
Example; I will tell her a story if she comes here.
(ii)               In other words:
If you begin with the If clause you end it with a comma.
Example;  1. If you speak so softly, I won’t hear you.
I won’t hear you if you speak so softly.
                  2. I will tell her a story if she comes here.
                        If she comes here, I will tell her a story.

(iii)             The verb in the If clause is in the simple present tense while the verb in the is in the simple future time.
FORM
If + Subject + the simple present tense (in the if clause) and

Subject + will/shall/can/may +infinitive verb (in the main clause.
OR
If + simple present + future
Example
1.      If she loves him, she will marry him.
2.      If I teach him, he can speak English.
3.      If you study hard, you will pass well the examination.
4.      If he comes, I will go there.
5.      If he goes to school late, he will be punished by the headmaster.
6.      If they miss the ship, they will travel by plane.
7.      If you bring us the books, we will read them at home.
In all the above sentences it is quite probable that actions indicted in the if-clause can be performed.

CONDITIONAL CLAUSE TYPE II (impossible/unlikely condition)
It is also known as unreal/closed/improbable/imaging condition.
Unreal condition suggests that an action cannot be fulfilled because the condition in the If-clause in type II is impossible for it indicates unreality.
Example;
a)      If he come. I would see him.
b)      If you told them, they would do the work.
c)      If he joined school, he would get same education.
In this case the actions indicated in the three If-clause are not expected to be fulfilled.
The verb in the if-clause is in the simple past while the verb in the main clause is in the conditional tense.
So in this type of conditional one is just imagining only.
FORM
If + simple past + would/could/should

More examples;
i)                    If I were Asha, I would not stay there. (But I’m not Asha)
ii)                  If I were God, I would heal all the inability people.
iii)                If you studied hard, you would pass your exams.
iv)                If Christopher went to England, he would see an England team.
v)                  If Martin came, we could go to town.
vi)                If you took the prefect form, you would be a prefect.
vii)              If my parent came to visit me, I would enjoy myself.
viii)            If I played hard, I would be selected to over seventeen team.
ix)                If my father was the president of this country, I would go to England.
x)                  If you lived near my office, you could come for tuition. (But you don’t live near my office, so you can’t)

CONDITIONAL CLAUSE TYPE III (unfulfilled/impossible condition)
It is talking about the actions which should have taken place in the past, but did not take place.
This kind of conditional sentences cannot be fulfilled because sentences refer to actions which should have been taken place in the past but did not take place.
The sentences are said to be hypothetical. This means that the time is past and conditional cannot be fulfilled because the action in the If-clause didn’t take place or happen.
FORM
If + past perfect (had) + past participle + would have + past perfect

a)      If she had bought a pen, she would have written a letter.
(But she did not buy a pen therefore she did not write a letter)
b)      If they had got money, they would have bought a new bus.

c)      If she had come here, I would have told her a story.

In this type of conditional sentence, the verb in the if-clause is in the past perfect tense, the verb in the main clause is in the perfect conditional.
Example
a)      If you had ran, you would have fallen down.
b)      If he had come, I would have seen him.
c)      If she had failed, she would have cried.
