初中英语定语从句小结 一 名词性从句: 1
主要包括主语从句,宾语从句,表语从句和同位语从句
一般由 that 引起,也可由 who, what, when, why, which, whom, whether, how 引起
主语从句很多情况下都可以放到句子后面,而用代词 it 作形式上的主语
形式宾语 4
由名词性关系代词 whatever, whoever, whichever 等引起的宾语从句 5
whether and if 都能引导从句, 但用法有所不同
当主语从句直接位于句首时,应用 whether,而不用 if
Whether 后能直接 or not, 但 if 不能
Whether he will come or not is not known
在名词 reason 后的表语从句必须用 that 引导, 不可误用 because
The reason why he is often late for class is that he has the bad habit of getting up late in the morning
二: 定语从句 1
引导定语从句的关系词有who, whom, whose, that, when, where, why and which
在非限制定语从句中, 只可用 which, who, whose, where , when
, 如果指代前面整个句子, 多用 which
当引导定语从句的先行词前有 all, any, no, little, much, very first 等词, 或先行词前为形容词最高级所修饰时,或先行词为 all, anything, nothing, something, everything 时,从句的引导词只能用 that
