請問such that和such as引導定從時有什麼區別啊?特別是句中缺少什麼的時候用as引導?

解答:

要明白這兩種定語從句,首先得從詞性和用法說起.
一、such
1.形容詞:這樣的,如此的,用於修飾名詞,如:
* He has a single parent,one of many such people in the neighborhood.他是單親,這地區附近有許多這樣的人.
* He has never dreamed of such wealth.他從未夢想過這樣的財富.
2.不定代詞:象這樣的人或物,直接用來作主語或賓語,如:
* He expected difficulties,and such occurred.預期會有困難,而這樣的困難果然出現了.
* Such are the fortunes of war.這些就是戰爭的機會.
二、as 用作關係代詞指代下面或前面提到的一句話,如:
* The statemant reads in full As follows:...聲明全文如下:...
(As 作從句謂語動詞 follows 的主語,指代 The statemant reads in full,也可以改寫爲:The statemant reads in full,which follows:...)
* As you well know,English is an importan tool in communication.衆所周知,英語是交流的重要工具.(as 是從句中 know 的賓語,指代 English is an importan tool in communication這件事)
三、that 也是關係代詞,但是與 as 不同的是它只指代先行詞,而不能指代句子(例句略).
四、明白上述道理,such that 和 such as 的區別就會迎刃而解,如:
* He expected difficulties,and such that could be avoided occurred at last.預期會有困難,而這種可以避免的困難最終還是出現了.(such 是不定代詞,指代 difficulties,關係代詞指代 such)
* He expected difficulties,and such avoided occurred as well know to everyone.預期會有困難,而衆所周知,這樣的困難果然出現了.
說得比較羅嗦,不知道能否解決你的問題.
