Verbal Ability - Spotting Errors - Discussion

Am not getting clarity. Can anyone explain once ?

It is one of the conditional clause. So according it "ayinatlithe ani vasta" we need to use would, could, should, might.

Can anyone say which book is very easy to learn grammar ?

This sentence should be conditonal perfect that means present/future time actions.

Ex: If you had spoken, they would have beleived you.

This sentence is an unfulfilled condition clause. According to the rule these sentence contain two parts i.e. Main clause & subordinate clause. The Rule of the subordinate clause is: If/when/suppose+subject+had+verb 3 and the Rule of the Main clause is: subject+would/could/should+have+verb 3

You are right ramesh.

These are the conditional sentences.

Present Conditional:

1. If I had the time, I would visit you today.
2. If I had better eyesight, I wouldn't need glasses.
3. If she went to school, she would learn english.

Past Conditional:

1. If I had gotten up earlier,I wouldn't have been late.
2. If they hadn't eaten all that ice cream, they wouldn't have gotten sick.
3. If she had known he was going to be their, she wouldn't have gone to the party.

Future Conditional:

1. If I practice My guitar, I'll become a better musician.
2. If she calls, I'll talk to her.
3. If they go shopping, Abdul will go with them.

Using if clause:
Unreal condition:
In the sub-ordinate clause----had+v3
In the main clause -------would/could+have+verb3

Example:
If I had studied well, I would have passed.

How is "this yesterday" correct?

If there is any compulsion to do a work then we use like.
have/has to,
is/are to,
was/were to
will have to ...etc.

Ex. (if you don't want to go to school but compulsory you have to go to school every day then use ->)I have to go to school.

Like that The given sentence showing to use. The person has compulsion to do help.So there should use"I will have to helped him." instead of "I will have helped him."
