Question

麻烦看看这2个完型填空

1 Something must be done to ___young people___smoke.
为什么用engcourage;not to不用make; not to
2 They are studying in the school ___last year.
A open B opened C opening D was opening
选哪个？为什么？
谢谢！

Answer 1

1.因为make 后面接动词原形，make do 或者make not do; 而encourage的用法是encourage sb.to do or not to do sth.

2. B. 因为这里要用个非谓语动词做school的后置定语，显然D不是非谓语形式，排除D；而school和open之间的关系是school was opened,应该用被动形式，因为这里要用非谓语动词，因此去掉be动词，直接用opened做后置定语，修饰scool.

Answer 2

encourage 表示劝说， 鼓励
make太强制了

C school opening表示开学

Answer 3

关于第一题 make的固定搭配是 make sb do sth
关于第二题 我觉得应该选择B 这是一道定语从句省略的问题，完整的是

They are studying in the school that/which opened last year

Answer 4

1 make sb do sth. 不能加to
2 选B 因为They are studying in the school 已经是个句子，结构完整，所以AD肯定错，BC选，school与open是被动关系 （open school）所以选B，这是过去分词做后置定语，修饰school
