There are many laboratory in this building.(改错)

There are many laboratory in this building.
- 改laboratory为复数laboratories.要跟前面的are还有many对应的
The students are main from China.
－ 改形容词main为副词mainly,副词才能修饰后面的状语.
This tastes very well.There is some meat in it.
－ 改副词well为形容词good,这里的taste是系动词,后面直接加形容词,表示偿起来.固定语法.
