Some think it is impossible to make friends with parents because they are so busy that they don't have enough time 14. (stay) with their kids. And some parents care more 15. their kids' schoolwork. That's why those students don't like to make friends with 16. (they) parents. 17. others don't think so. For example, Lucy 18. (think) parents can be our friends.

13. ideas 14. to stay 15. about 16. their 17. But 18. thinks 19. broke 20. laugh 21. the 22. more

13. 空格前different意为“不同的”，后接可数名词复数，idea的复数形式是ideas。
14. 此处考查固定搭配have enough time to do sth.，意为“有足够的时间做某事”，填不定式to stay。
15. 此处考查固定短语care about，意为“关心、在意”，符合语境，填about。
16. 空格后是名词parents，需要用形容词性物主代词修饰名词，they对应的形容词性物主代词是their。
17. 前文介绍部分学生认为没法和父母做朋友，后文说其他人不这么认为，表转折，句首首字母大写，填But。
18. 主语Lucy是第三人称单数，句子为一般现在时，谓语动词要用第三人称单数形式thinks。
19. 时间状语Last month表示“上个月”，句子用一般过去时，break的过去式是broke。
20. 此处考查固定搭配make sb. do sth.，意为“让某人做某事”，填动词原形laugh。
21. 此处考查固定搭配the same as，意为“和……一样”，填定冠词the。
22. 空格后有than表示比较，要用形容词比较级，much的比较级是more。
