三、what/whatever与
which/whichever的区别
what/whatever意为“什么/无论什么”，描述的事物在上下 文中没有范围；which/whichever意为“哪个/无论哪个”， 描述的事物在上下文中有范围。 To be honest, I can hardly understand what/whatever you have said. Here is the dress. This is what I have been dreaming of. Here are many beautiful dresses. You can choose whichever you like.
高考英语语法完全讲解 名词性从句
定义及分类
在句中起到名词所能充当的句子成分的从句称之 为名词性从句，名词常用来作主语、宾语、表语、 同位语，因此，对应的名词性从句可以分为四大 类：主语从句、宾语从句、表语从句、同位语从 句。
主句从句
1、作句子主语的从句叫作主语从句。 2、为避免句子头重脚轻，常用形式主语it代替主语从 句，把主语从句置于句尾。常用的句型有：It is/was+ 形容词/名词/过去分词+that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.
同位语从句
同位语从句说明其前面名词的具体内容。通常由that引 导，常接同位语从句的名词有：news, conclusion, possibility, rumor, certainty, story, word, mystery, idea, doubt, hope, truth, question, belief, fact, message, evidence, information, explanation, rule, probability, question, wish, thought, statement, report, opinion, principle等。

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。

英语中的从句—名词性从句
名词性从句定性
名词性从句顾名思义在句子中起到名词成为的一部分句 子。名词在句子中可以担任主、宾、表、同位语。 在一个句子中从句占据的位置不同就是不同从句，比如 占据主语的位置就是主语从句，占据了宾语就是宾语从 句。
英语中的从句—名词性从句
引导名词性从句的关联词 从属连词 that\ whether \if\as\as if（只有连接的 功能，不充当语法成分） 连接代指词who、whom、which、what、 whose和wh+ever 连接副词where、when、why、how
如何使用关系代词和关系副词 1、看句子中的谓语动词。VT（及物动词）后无宾语，就必须用关系代词，不及物动 词若缺少介词，则必须用关系副词。 e.g. This is the town where i stayed before.
This is the town at which i stayed before. This is the town which i visited before. 2、看先行词在后面的从句子中做什么成分，来选择正确的关系词。如果先行词在后 面的从句中缺少定冠词，还需在关系词前补足定冠词。 e.g. Is this the museum which you visited yesterday. Is this museum the one you visited yesterday. This is the museum where i went yesterday
The fact surprised us.
