가정법 정리 1

 

  

First conditional 

 

#1 the verb in the if clause is a simple present verb, and the verb in the main clause is will + base form of the verb. 

A sentence can begin with either clause with no change in meaning. Remember that a sentence that begins with an if clause is followed by a comma.

 

If it’s sunny tomorrow, I will go to the beach.

 

#2 It is possible to have a negative verb in the if clause, the main clause, or both. The contraction of will not is won’t

 

If I don’t pass this test, my parents will be very angry.

If I’m not late for work again, I won’t have to look for another job.

 

#3  The verb in the if clause will end in -s if the subject is third person singular.

 

If she watches that sad movie, she will cry

 

#4 Though not as common, it is possible to use be going to + base verb or the present progressive ( which are the two other ways of forming the simple future in English)

In place of will + base verb with no change in meaning.

 

For example, these sentences all have the same meaning.

 

If it doesn’t rain, we will go for a walk ( will + V)

If it doesn’t rain, we are going to go for a walk. ( be going to + V)

If it doesn’t rain, we are going for a walk. ( be+ ing V)
