1.概念 在句子中起名词作用的句子叫名词性从句。
名词性从句的功能相当于名词词组,它在复合 句中能担任主语、宾语、表语、同位语、介 词宾语等, 因此根据它在句中不同的语法功能, 名词从句又可分别称为主语从句、宾语从句、 表语从句和同位语从句。

表语从句
位于系动词之后作表语的从句叫表语从句。 The problem is who is to pay and when we can start.

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。

考点一 连接词 that / what 的选用
总结归纳：
that 和 what 都可引导所有的 名词性从句。但是，_w_h_a_t__除起连 接作用外，还在名词性从句中充当 成分，可作从句的_主_语__、_宾_语__、 _表___语___、或_定__语_。而_th_a_t__在名词性从 句中不充当任何成分，只起 __连__接___作用。
• 步骤二：如果从句中既不缺少主语，宾语， 表语，定语，但是缺少一定意义的状语， 则考虑用连接副词；
• 步骤三：如果既不缺少主语，宾语，表语， 定语，也不缺少状语，则考虑用从属连词。
