你好!
定语从句先行词的前面不一定要用定冠词the,这取决于被从句所修饰的名词是特指还是泛指。
Don't forget the book that I told you to bring. 特指我要你带的那本。
A doctor is a person who looks after people's health. 泛指医生。
以上仅供参考!
不是。有时可以用a,不可数名词的话前面有时也可以不用。下面我举三个简单的例子让你明白:1)give me the book which you think is good.把这本你认为好的书给我吧! 2)give me a book which you think is good .给我一本你认为好的书。 3)give me some bread which you bought just now.给我点你刚买的面包。
定语从句先行词前必须用the 吗
不一定有the的
有其他的物主代词也是可以的
比如 my his her等
不一定加the的
