[用法体悟] ①为主语从句。What(＝The thing that)在从句中作主语。 ②为表语从句。从句本身意思完整，不缺任何句子成分。 ③为同位语从句。补充说明doubt的具体内容，因doubt (疑惑)的意思本身是不确定的，故由whether引导。 ④为同位语从句。说明the cause的具体内容。 ⑤为主语从句。表示“如何”变得更苗条和更健康，故用how引导，how在从句中作方式状语。 ⑥为主语从句。表示去“哪里”咨询、向“谁”咨询，故分别用where, who引导。 ⑦为同位语从句。说明suggestion的具体内容，从句内容完整，不缺任何句子成分。 ⑧为宾语从句。从句内容完整，不缺句子成分。 ⑨为宾语从句。when在从句中作时间状语。 [系统中整合规则] (一)主语从句　 1．that引导的主语从句 that引导主语从句时，在从句中不作任何成分，也没有词汇意义，但一般不可省略。 That the earth goes around the sun is known to all. 众所周知，地球围着太阳转。 2．whether/if引导的主语从句 主语从句位于主句谓语动作前，表示“是否”，只能用whether。若用it作形式主语，则whether与if可互换。 Whether we can have clean drinking water lies in what effective measures will be taken by the government about water pollution. 我们能否有干净的饮用水依赖于政府对水污染将采取什么样的有效措施。 3．wh-类连接词引导的主语从句 wh-类连接
