定语从句中的先行词是复数名词时能不能用that
可以,不过有几种情况是只可以用which不能用that。
定语从句中的关系代词 that 或 which 既可以指代单数先行词,也可以指代复数先行词。指代复数先行词时,要注意从句的谓语动词要与复数先行词保持数的一致。例如:
This is the parcel that is going to beposted. 这是准备要寄出的包裹。
These are the parcels that are going to beposted. 这些是准备要寄出的包裹。
必须注意的问题
(1)关系词作主语时,从句中谓语的数。
(2)注意区别定语从句与强调句。
①定语从句中关系词作从句成分,复合句。
②强调it无意义,that/who不是引导词。
③强调it is/was和that/who后如果句子意思讲得通则是强调句,讲不通则不是。
It is the museum that/which we visited last year。(定语从句)
It was in the hotel that we stayed last night。(强调句)
(3)定语从句与同位语从句的区别。
①定语从句引导词被称为关系词,that充当主语、宾语、表语。有时可省略。
②同位语从句引导词被叫做连词,that不能充当任何成分,不可省。
Word came that their army was defeated。(同位语)
We expressed to them our wish that was the same as their。(定语)
(4)关系词在从句中省略的情况。
①关系词作宾语,前无介词时。
②关系词作表语。
(5)限制性定语从句与非限制性定语从句的翻译。
(6)关系词前有介词或复杂介词,关系词只能是which和whom。
This is the parcel that is going to beposted. 这是准备要寄出的包裹。
These are the parcels that are going to beposted. 这些是准备要寄出的包裹。
