I wonder if those sentences are right
2个回答

一,(1)we will find out what they want to hear.

(2)he asked how long the Great Wall is.

都正确,

(1)句 主句用将来时,从句用一般现在时 是英语的常规用法

(2)句 主句用了过去时,而从句用一般现在时 是因为从句表述的是一个一般的常识性的东西-长城的长度,所以可以用一般现在时

二,选择

the teachers's smile made her ___ better.

选A 是因为make sb do sth 是固定搭配,make 后面动词要用原形
