Conditionals / If Clause - Sample Questions

In conditional sentences, there is an 'if clause' and a 'main clause'.  The structure of the if clause and the main clause are as given below in the three different conditionals

First Conditional or Probable Condition

If + present            -    will / shall etc. + infinitive

If you work hard, you will succeed.

This sentence refers to the future and the action mentioned in the main clause is likely to happen.

Second Conditional or Improbable Condition

If + past                -    would / should etc. + infinitive

If you worked hard, you would succeed.

This is an imaginary situation and the action mentioned in the main clause is not likely to happen.

Third Conditional or Impossible Condition

If + past perfect    -    would / should etc. + have + past participle

If you had worked hard, you would have succeeded.

This refers to the past action which did not happen.

In the higher secondary examinations there are two types of questions related to this grammar topic.  One is to fill in the blanks with the correct usage.  The other is to correct a sentence given with a wrong combination of if clause and main clause.

For example, this is from March 2020 examination:

Use appropriate forms of the words given in the brackets to fill in the blanks.

1. Hawking commented in his customary style, 'If I _____ (get) a first, I shall go to Cambridge.

2.  Ivan Ivanich said to his brother, "If I were young, I _____ follow my dreams as you did."

In the first question the main clause (I shall go to Cambridge) is as in the first conditional.  So the conditional clause should use the present tense. The present form of 'get' is 'get'.  So the answer is 'get'.

In the second question the conditional clause is having if + past (were).  So it is second conditional or type 2 conditional.  So the main clause should have would + infinitive.  So the answer is  'would follow'

1.  If I won a lottery, I would have bought a car.

2.  If it rains, we would cancel the trip.
