《名词性从句讲练》PPT课件.ppt

Noun Clause,The Noun Clause 在句中充当名词成分. 也就是说做主语, 宾语,表 语, 同位语. 于是就形成了主语从句,宾语从句,表语从句和同位语从句. e.g.同一个词引出的句子，在不同的位置，引出不同的从句。 We all know that the earth is round. That the earth is round is known to us all. The truth is that the earth is round. Do you believe the truth that the earth is round?,名词性从句 名词性从句包括主语从句、表语从句、宾语从句和同位语从句。 1. 陈述句作名词性从句, 用 that 引导, 在从句里不作成分, 但不能省 (除宾语从句)。 2. 一般疑问句作名词性从句, 只能用 whether 引导 (除宾语从句用if / whether 均可)。 3. 特殊疑问句作名词性从句, 用连接代词 who / whose / whom / what / which / whoever / whomever / whatever / whichever 和连接副词 when / where / why / how / whenever / wherever / however 引出。 4. 从句中用陈述句的词序。 5. 在名词性从句中, “无论谁”、“无论什么”, 只能用whoever / whatever, 但在让步状语从句中, whoever / whatever 和 no matter who / no matter what 均可。,Warm-up exercise:,1. _food is related to illness is not a new discovery.
