1、should表示需要完成的事情,而不是普遍需要掌握的
2、whoever是强调了who 也可以使用who而who就与the one类似,你懂得、、、
3、因为是不怀疑的句子所以他是否来时肯定的回答,这是固定搭配要记得!
4、过了好像有几个小时他出来了带着苦笑.
5、无法解释,固定搭配
6、我的内心里的是 什么东西,不是怎么!
7、what president can do 是一个句子里的成分.用that就不能做主语或宾语.
8、对于公众来说不容易懂得一个新发明能够给人类带来什么作用.
9、in 是介词连which case,which是指这句话之前的事情,非限制性定语从句 只用which 你没认真看which 和that的使用规则哦.
10、which 也可以、、

不知道

it is necessary /strange/important... that 后面用虚拟语气，动词构成 should +do
