Grammar: Conditional 3 / Wishes 

I. Conditional type 3 

‎[If + Subject + Verb (past perfect) + complement] 

[subject + would + verb (present perfect) + complement]‎

  • If she had taken her umbrella, she wouldn’t have gotten wet
  • Tom would have had better marks if he had revised his lesson.

‎ Example ‎

‎ Source sentence: I didn’t play sports. I was fat.‎

‎ Target sentence: If I had played sports, I wouldn’t have been fat.

The use of conditional type 3

When we use conditional type 3, we refer to an impossible situation in the past. We wish for the opposite of that situation.

Last month Ann was sick. Her friend Joan didn’t know this, and she didn’t go to see her. They met again after Ann got better.

Joan said :

If I had known that you were sick, I would have gone to see you.

”This means that she didn’t know Ann was sick, so she said:““If I had known….”“This means that Joan didn’t know Ann was sick, so she said: “If I had known….”

And she didn’t go to see her.

II. Wishes

Steps to follow :

  • We look at the verb in the source sentence, if it is in the simple present, then we change it to the simple past, and if it is in the past, we change it to the past perfect.

Present wish: 

It is a situation in the present that we don’t like, or we like to have it the other way.

Tom lives far from school, so he usually arrives late.

Tom: I wish I didn’t live far from the school. If only I didn’t live far from the school.

Source sentence: I don’t play sports. I am fat.

Target sentence: If only I played sports / I wish I played sports

Past wish:

It is a situation in the present that we don’t like, or we like to have it the other way.

Tom had an accident because he drove very fast. If only he hadn’t driven very fast, or Tom wishes he hadn’t driven very fast.

TIP: Look at the verb. If it is affirmative, change it to negative; if it is negative, change it to affirmative.

Source sentence: I didn’t play sports. I was fat.

Target sentence: If only I had played sports. / I wish I had played sports
