Jawaban:

1. To repair cars is the work of a mechanic.

2. My sister intends to take up computer science.

3. Mark continued to neglect his work in the office, so he was fired.

4. Ever since he began his new business, he started to regain his capital.

5. He always preferred to lead the team.​

Penjelasan:

Dengan penggunaan verb tertentu, gerund dapat digantikan dengan to + infinitive. Tapi ada verb tertentu yang harus diikuti oleh gerund, atau sebaliknya ada yang harus diikuti to infinitive.

Contoh lain yang bisa keduanya:

I like to swim

I like swimming before breakfast.

Contoh yang hanya boleh diikuti to + infinitive:

I want to go home

Contoh yang hanya boleh diikuti gerund:

He enjoys singing karaoke so much.
