Writing Task 2. Complete the sentences with second and third conditionals.
5. If my sister(have) a degree, she(love) working on animal conservation. (II)
6. If we(arrive) earlier, we(see) John. (III)
7. If they(go) to bed early, they(not / wake) up late. (lll)

5. If my sister had a degree, she would love working on animal conservation.
- Explanation:
In this sentence, we are talking about a hypothetical situation in the present or future. The first part of the sentence uses the second conditional, which is used to talk about unreal or unlikely situations in the present or future. "If my sister had a degree" suggests that it is not currently true that she has a degree. The second part of the sentence uses the simple conditional (would + base verb) to express the result or consequence of the hypothetical situation. "She would love working on animal conservation" suggests that if she had a degree, this is how she would feel or what she would do.

6. If we had arrived earlier, we would have seen John.
- Explanation:
In this sentence, we are talking about a hypothetical situation in the past. The first part of the sentence uses the third conditional, which is used to talk about unreal situations in the past. "If we had arrived earlier" suggests that it is not true that we arrived earlier. The second part of the sentence uses the perfect conditional (would have + past participle) to express the result or consequence of the hypothetical situation. "We would have seen John" suggests that if we had arrived earlier, this is what would have happened.

7. If they went to bed early, they would not wake up late.
- Explanation:
In this sentence, we are talking about a hypothetical situation in the present or future. The first part of the sentence uses the second conditional, which is used to talk about unreal or unlikely situations in the present or future. "If they went to bed early" suggests that it is not currently true that they go to bed early. The second part of the sentence uses the negative simple conditional (would + not + base verb) to express the result or consequence of the hypothetical situation. "They would not wake up late" suggests that if they went to bed early, they would not wake up late.
