题目

英语20.Only those ______ knew well could be enrolled in the course.
20.Only those ______ knew well could be enrolled in the course.
A.who B.he C.that D.people
为什么?

答案

选C.
Only those that knew well could be enrolled in the course.
这是一个定语从句,that knew well 修饰先行词those
用到的语法点是定语从句部分
“当先行词前有the,only等修饰时,连接代词要用that而不能用 who”.
当去掉“only”时
Those who knew well could be enrolled in the course.
才通顺.
再者,题中若能选who的话,that也是完全正确地能替代它,这就有两个答案了,明显who不选.
