特殊考点
04
只用that 的情况
(1)当先行词被序数词或形容词最高级修饰时。
Eg. This is the most delicious food that I have ever had.
(2)当先行词是 all,little,few,much,any,everything,anything,nothing,none 等不定代词或被这些词修饰时。
Eg. Tell me everything that you know.
(3)当先行词被 the only,the very,the last,the same 等修饰时。
Eg. This is the very book that I want to buy.
(4)当先行词既包括人又包括物时。
Eg. He asked about the factories and workers that he had visited.
(5)当主句是以 who,which 开头的特殊疑问句时。
Eg. Which of the books that had pictures was worth reading
只用that 的口诀: 多少不一,恰人物最虚
(1)多少:从少到多 no, none, neither, little, few, a little, a few, much, many, all, each, both;
(2)不:不定代词 some- -thing,any- all every- none no- neither…
(3)一:一个 ,唯一 the one; the only;
(4)恰:恰好 the very\the right+先行词
(5)人物:先行词中有人又有物;
(6)最:形容词最高级+先行词;
(7)虚:序数词+先行词(the first\the next\the last+先行词)
(1)引导非限制性定语从句时。
Eg. Crusoe’s dog,which was very old then,became ill and died.
(2)当关系代词前有介词时。
Eg. The building in which Han Mei studied was very old.
(3)先行词本身是 that 时。
Eg. What’s that which flashed in the sky just now
(4)在限制性定语从句中,如果有两个定语从句,其中一句的关系词是 that,那么另一句的关系词宜用 which。
Eg. Let me show you the novel that I borrowed from the library which was newly open.
宜用 which 不宜用 that 引导定语从句的情况
