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。

whichever (book) you like.
whose
• Whose表示“谁的”。 • 在句子中充当定语的成分，其后一定会加
when, where, how, why, however… when, where, how, why, however…
that的用法
• 在从句中不充当任何成分，也没有任何具体意思。 • 引导的句子相当于一个陈述句。 • 只起到连接的作用。
主语 做及物动词宾语
宾语 做介词宾语
表语 同位语

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。

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”

【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。
