英语中哪个时候用which need哪个时候用which needs?感觉应该which 表示单数,该用needs?请举例说明~

Answer 1

你提的问题应该是属于定语从句的用法.在定语从句中,which只是个引导词,后面用单数还是复数（一般现在时的情况下）取决于该从句修饰的词的单还是复数形式.例如：
There are some advice which needs to be modified.(这有些建议需要修改.) 该题中advice是不可数名词,是单数形式,所以后面用which needs； There are some houses which need reparing.(这有些房子需要维修)该题中which 从句修饰的是houses,名词复数,因此后面用need.
