定语从句
复合句 名词性从句
状语从句
请思考 定语从句的定义：
起定语作用，用来修饰名词或代词的从句。
名词性从句定义
起名词性作用的从句，叫名词性从句。 换言之，在英语的句子结构中，本来该由名词充当的 主语、宾语、表语和同位语部分，换由一个句子来充 当，这样的句子就是名词性从句。
大家有疑问的，可以询问和交流
可以互相讨论下，但要小声点
3. We love peace.
(名词作宾语)
4. He said that he has known all before.
(从句作宾语)
2. 在句中充当及物动词或介词或be+adj.后宾 语的从句叫做宾语从句。
We always mean what we say.我们向来说话算数。
7.Miss. Liang , a 24-year-old girl, teaches us
English .
(名词作同位语)
8.The news that our team had won made us happy.
(从句作同位语)
4. 在句中用作同位语的从句叫做同位语从句. 其用途是对前面的名词作进一步解释，说明 该名词的具体内容。可以跟同位语从句的名词 通常是news,idea,fact,word,hope,advice等。
(同位语从句)

the whole school.
(宾语从句)

3. 连接副词：when(＝the time when什么时候，何时)，where(＝the place where什么地方，何地)，how(＝the way that/in which怎样， 以……方式，如何)，why＝the reason why为什么)。它们除起连 接作用，还在从句中作状语。
3) wh类连接词引导的主语从句： wh类连接词包括wh类的连接代词(who, whom,
whose, which, what, whoever, whomever, whichever, whatever等)和连接副词(when,
where, how, why, whenever, wherever, however 等)。what, when和wh-ever类的词有时可不表 疑问。wh类连接代词在句中既起连接作用， 又可充当主语、宾语、表语、定语等成分。 wh类连接副词在句中起连接作用，在从句中 可充当时间、地点、原因、方式状语。
【温馨提示】 ①whether/ if引导宾语从句表示“是否”
的意思时，一般情况下可互换。 ②if引导宾语从句时可以有否定式，而
whether从句则没有。 e.g. I don’t care if he doesn’t come.
5) 特殊疑问词引导的宾语从句： 由who, what, how, which, whose, where, why等词引导的宾语从句，可作动词、 介词及形容词的宾语。
【温馨提示】 doubt, doubtful与sure后名词性从句连接词 that, whether, if的选择。 ①当doubt, doubtful用于肯定句时，后面的名
词性从句的连接词常用whether或if；当 doubt, doubtful用于否定句或疑问句时，后 面名词性从句的连接词用that。

(that在从句中不充当任何成份)
