Answer 1

If Ana had known the answer, she (raise) would have raised her hand.

Mr. Diaz (be) would have been on time to work if he had taken the bus.

If Angela hadn't brought a jacket, Luis (give) would have given her his coat.

Sofia would have bought a new cell phone if she had had (have) enough money.

If Mrs. Garza (know) had known how cold it was outside, she would have worn a coat.

If Adriana had realized how tired she was, she (stay) wouldn't have stayed out so late.

If Javier had checked his watch, he (know) would have known how late it was.

If we had known how late the bus was going to be, we wouldn't have waited (not wait) for it.

Step-by-step explanation:

In these sentences, we have to use the third conditional. We use the third conditional to talk about imaginary situations in the past, things that we wish had happened, or regrets in the past.

To make sentences in the third conditional, we have to use the if +past perfect +would have + verb in the past participle. The if clause can be at the beginning or at the end of the sentence. When it is at the beginning, we have to write a comma at the end of it, but when it is at the end, we do not have to use a comma after the if clause.

Answer 2

1. I Ana had known the answer, she would have raised her hand.

2. Mr. Diaz would have been on time to work if he had taken the bus.

3. If Angela hadn't brought a jacket, Luis would have given her his coat.

4. Sofia would have bought a new cell phone if she had had enough money.

5. If Mrs. Garza had known how cold it was outside, she would have worn a coat.

6. If Adriana had realized how tired she was, she wouldn't have stayed out so late.

7. If Javier had checked his watch, he would have known how late it was.

8. If we had known how late the bus was going to be, we wouldn't have waited for it.

Step-by-step explanation:

This question requires knowledge about the third conditional.

The third conditional is used in English to express hypothetical situations in the past. In other words, we are imagining possibilities about something that has already happened. For example, suppose you forgot to bring some money with you. Because of that, you weren't able to buy a jacket you saw that was on sale. You can imagine how things would have been: "If I had brought some money, I would have bought that jacket."

The structure of the third conditional is the following:

if + had (not) + past participle, would/could/might (not) + have + past participle

The if clause will not necessarily be the first one every time. Take a look at the examples below:

- She would have told you if she had known how important it was to you.

- If you had talked to me about it, we could have found a better way to do it.

- If Mario hadn't moved away, he and Dana would have gotten married.
