二、名词性从句的写法 名词性从句是学生在写作中喜欢尝试的 复杂句，在写作时可采用“三步法”：
[示例]
第一步：写出两个简单句。
①He said a lot at the meeting.
②His words were very attractive.
第二步：让句①作主语从句，可转换为“他在会上所说的话”，即what he said at the meeting。 第三步：把句①转换的主语从句和句②连在一起。 What he said at the meeting was very attractive.
[即时演练] 把下列每组题中的两个简单句合并为一个含有名词性从句的复合句 1．When did you enter the room？ The police wants to know it. ____________________________________________________________________

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。

The idea that computers can recognize human voices surprises many people.
(that在从句中不充当任何成份)
The idea （that/which） he gave surprises many people．
(that在从句中作gave 的宾语)
宾语从句须注意
1) 由疑问词引导的从句中, 词序按陈述句 顺序排列。
e.g. I wonder what he is doing. 注意：I wonder what was wrong /the matter
with him. 2)当主句的谓语动词是过去时的时候, 从句的 谓语动词应用相应的过去时。自然规律和客观 真理例外。
4) That在其他名词性从句中均不可省略，只有 在宾语从句中that有时可以省略，但在并列 的宾语从句中第二个that 不可省略。
e.g. He said (that) he would leave and that he would never come back again.
5) 否定的转移 若主句谓语动词为think, consider, suppose, believe, expect, fancy, guess, 等, 其后的宾语 从句若含有否定意义, 一般要把否定词转移到 主句谓语上, 从句谓语用肯定式。 e.g. I /we don’t think this dress fits you Well, does it?
3. 连接代词: what, whatever, who, whoever, whom,whose, which（哪个）： 不仅起到连接一个句子的作用,同时也是从句 的一个组成部分；从句不完整，缺成份。
