1. in （固定搭配in great danger“处于极大危险中”）

3. people's （名词所有格“人们的日常生活”，people的所有格是people's）
4. eating （固定搭配go on doing sth.“继续做某事”）
5. their （形容词性物主代词修饰名词homes，they的形容词性物主代词是their）
6. will help （全文谈论未来，用一般将来时will+动词原形）
7. doing （固定搭配spend time doing sth.“花费时间做某事”）
8. either （否定句句末表示“也”，用either）
9. what （宾语从句中缺少like的宾语，用what表示“他们喜欢的事情”）
10. will be （一般将来时will+be动词原形，be able to“能够”）
