课前热身： 猜谜语： 1、Which letter is an animal? 2、Which letter stands for the ocean? 3、What room has no walls, no doors, no windows, and no floors? 课前回顾 一、名词性从句 (Noun Clauses） 1、定义和分类：在句子中起名词作用的句子叫名词性从句 (Noun Clauses）。名词性从句相当于名词，在句中做主语、表语、宾语和同位语。因此，名词性从句可分为主语从句、表语从句、宾语从句和同位语从句。 · 1. When we will start is not clear. 主语从句 · 2. Mrs. Black won’t believe that her son has become a thief. 宾语从句 · 3. My idea is that we should do it right now. 表语从句 · 4. I heard the news that our team had won. 同位语从句 2. 连接词 1 从属连词 that / if / whether that 无词义，在句中不担任成分；if / whether 有词义，但在句中也不充当成分。 2 连接代词 who / whom / whose / what / which 有词义，并在句中担任主语、表语、宾语或定语等成分。 3 连接副词 when / where / why / how 有词义，并在句中担任状语的成分。 本节课重点 表语从句Predicative Clause 1、 概念： 用作表语的从句叫表语从句，它位于主句中的系动词之后。 表语是用来说明主语的身份、性质、品性、特征和状态的，表语常由名词、形容词、副词、介词短语、不定式、动词的-ing、从句来充当，它常位于系动词(be, become, appear, seem, look, sound, feel 等词)之后。 如果句子的表语由一个句子充当的，那么这个充当表语的句子就叫做表语从句。 The question is whether our meeting should be put off. He is a lazy boy and that is why he is always late for school. 二、表语从句的引导词有以下几类： 主语 +系动词be //link v. +表语从句 第一类： 从属连词that，whether, as if = as though , because （注意，不能用if ） What I mean is that we should help each other. 我的意思是我们应该互相帮助。 The problem is whether we can finish the work on time. 问题是我们能不能按时完成工作。 　He looks as if he's tired. 他好像累了。 It looks as if it is going to rain tonight. 看起来好像今晚要下雨。 It sounds as if someone is knocking at the back door. 听上去好像有人在敲门。 I feel as though the house is shaking. 我感到好像房子在晃动。 It's just because he doesn't know her. 这是仅仅因为他不认识她。 The reason why he was absent from work was that he was seriously ill. ♥ because的句型是That/This/It is because---- 第二类： 连接代词who, whom, whose, what, which, whoever, whatever, whichever What concerns me most is who will be my teacher next term. That's what he wants. The city is no longer what it was ten years ago. Wha
