⑤ 当先行词本身为不定代词如anything, something, nothing, everything, all, much, few, little, none, the one时。 e.g. All that I want is peace and stability. There is little that I can do. There is nothing that I can tell you. I have tried everything that I can think of. I do not mean this one. I mean the one that was bought yesterday. 注意：anybody, nobody, everybody等不在此列。 不能使用that的情况 ① 当定语从句前有介词时，关系代词不能用that。 ② that不能用于非限制性定于从句。 ③ 当先行词为one, ones, anyone, those, 指人时，用who。 e.g. Those who learn not only from books but also through practice will succeed. ④ 当先行词是he时，用who。(多谚语) e.g. He who plays with fire gets burnt. He who laughs at last laughs best. ⑤ 当先行词本身是that时，用which或who避免重复不能用于非限制性定于从句。 e.g. What’s that which flashed in the sky just now? whose的用法 ? whose作定语从句中的定语，表示所修饰的“某（些）人的”或“某物的” 。 e.g. The boy whose name is Tom is the top student in my class. Look at the house whose roof is red. 注意： 当whose指代物时，whose+从句结构 =…of which+从句 =of which the…+从句 e.g. Look at the house whose roof is red. Look at the house, the roof of which is red. Look at the house, of which the roof is red. 这就是那位成绩卓越的科学家。 This is the scientist whose achievements are well known. = This is the scientist, the achievements of whom are well known. =This is the scientist of whom the achievements are well known. as的用法 1) as用于限制性定语从句 so …as；such…as；the same…as； We have found such materials as are used in their factory. 我们已经找到了像他们工厂里用的那种 材料。 He is not the same man as he was. 他和过去不同了。 2) as用于非限制性定语从句中 as可以替代整个句子，而不是主句中的某一个词；which 既可以替代整个句子，也可以替代主句中的某一个词。as既可以在主句前，又可在主句中、主句后，而 which引导的非限制性定语从句一般放在 主句之后。 As is known to everybody, the moon travels round the earth. = The moon travels round the earth, as/which is known to everybody. =It is known to everybody that the moon travels round the earth. =What is known to everybody is that the moon travels round the earth. 3) as的习惯用语 as we all know 众所周知 as is well-known 众所周知 as has been said before 如上所述 as we had expected
