Question

Tom and his dog which were here a moment ago have disappeared.改错.是把which改为that 想知道为什么

Answer 1

下列情况下,只能用that或省略关系代词,绝不能用which.
1.当先行词是不定代词all,much,something,everything,anything,nothing,none,the one时；
2.当先行词前面有only,any,few,little,no,very,last等词修饰时；
3.当先行词是形容词最高级时或它的前面有形容词最高级时；4.当先行词是序数词或它前面有一个序数词时；
5.当先行词人+物并用时；
6.当主句的主语是疑问词which时；
7.有两个定语从句时,其中一个关系代词已用which,另外一个宜用that.
8．The way +定语从句,that=in which 可省略
