that 和 it 在做代词的时候有什么区别?》
题：People think _____ is more and more important to protect the enviroment.
A.that B.it
答
选B
这里是一个固定结构It is + adj. + to do sth.
如果要选that，其指代成分应为不可数名词或其后面跟一个定语
答
选b
这是一句宾语从句。
从句也应有主语，而这里的it是一个代词，中间省略了that。
即 people think (that) it is more and more important to protect the environment.
that 也可在定语从句中作代词。 但必须前有一个名词.
The pen that you bought yesterday is broken.
答
选B. 这是固定句型!sb think it is ...be +adj
