Learning About Language —语法·提升语言能力 课时目标 1.归纳词缀，学会使用构词法整理、记忆词汇。 2.感知表语从句的结构特点并思考其表意功能。 3.能够在语境中正确理解和使用表语从句。 语法项目——表语从句 初识语法——在美文运用中体悟　 I never really cared about my appearance. That's ①why I couldn't understand my sister, who has 17 lipsticks and can't decide which one she uses every morning. Last month I attended a TV program, A NEW YOU. For the first time I saw myself as a handsome young man. What I realize is ②that external beauty is not totally useless. It's true that inner beauty is important, but external beauty shouldn't be overlooked. That being healthy is beautiful is ③what I agree to. What I want to say is ④that we should have a correct attitude to our appearance. ①why引导表语从句，在从句中作原因状语； ②that引导表语从句，起连接作用，在从句中不作成分； ③what引导表语从句，在从句中作宾语； ④that引导表语从句，起连接作用，在从句中不作成分。 慧学语法——运用“形式—意义—使用”三维动态语法观　 在主从复合句中充当表语的从句，叫作表语从句。表语从句位于系动词之后，说明主语是什么或者怎么样。表语从句可由从属连词、连接代词或连接副词来引导。 [自主感知] ①Oliver believes that with a million pound bank note a man could survive a month in London. ②It is Henry Adams, an American businessman, who is lost in London and does not know what he should do. ③I wonder, Mr Adams, if you'd mind us asking a few questions. ④I didn't know whether I could survive until morning. ⑤(教材P2典句)One theory was that bad air caused the disease. ⑥(教材P2典句)The other was that cholera was caused by an infection from germs in food or water. ⑦(教材P3典句)The truth was that the water from the Broad Street pump had been infected by waste. [会发现] (1)以上7个句子中的蓝体部分都是从句，这些从句在词性上相当于一个 词，故被称作 从句。 (2) 中的蓝体部分属于表语从句。 名 名词性 ⑤⑥⑦ [规则点拨] 一、表语从句连接词的用法　 1．连接词that/whether that和whether在表语从句中不作任何成分，that无实义，但whether仍保留“是否”的意义。 The trouble is that she has lost his address. 麻烦的是她弄丢了他的地址。 My suggestion is that we should tell him. 我的建议是我们应该告诉他。 The question remains whether they will be able to help us. 问题还是他们能否帮我们。 [名师点津]　if不能引导表语从句。 2．连接代词 引导表语从句的连接代词主要有：who, whom, whose, what, which, whoever, whatever, whichever等。 The problem is who we can get to replace her. 问题是我们能让谁去替代她。 Tom is no
