Revise some words and expressions they have learned yesterday. 2. Check the homework. Step 2 表语从句一、定义：

4、1. 表语从句（Predicative Clause）：在一种复合句中，用一种句子作为主句的表语成分。阐明主语是什么或者怎么样，表语从句对主句主语进行阐明、解释，使主语的内容具体化；表语从句只能置于主句之后，而主句的动词只能是联系动词；可以接表语从句的连系动词由be, look, remain, seem等。Eg: The problem is puzzling. 这问题令人困惑主语 连系动词 形容词作表语The problem is when we can get a pay rise. 问题是什么时候我们可以得到加薪.主语 连系动词 一种句子作表语-表语从句He has become a

5、teacher. 她已经成为一名教师。 He has become what he wanted to be ten years ago. 她已经成为了她前想成为的。She has remained there for an hour. 她曾在那里停留了一种小时。 She has remained where I stood yesterday for an hour. 她始终在我昨天站的地方站一种小时。His suggestion is good. 她的建议是好的。His suggestion is that we should stay calm. 她的建议是，我们应当保持冷静。2. 连接

6、表语从句的连接词有：1.附属连词that、whether、as though(if)；That引导表语从句时，在口语中，间或可以省略。2.关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等；3.关系副词when, where, why, how, however, whenever, wherever等。4.由连词because，as if/as though等引导的表语从句1.由附属连词that，whether引导的表语从句。that在引导表语从句时无词义，而whether有词义，意为、“与否”

7、。这时主句的主语常常是些抽象名词，如question(问题)，trouble(麻烦)，problem(问题)，result(成果)，chance(也许性)，suggestion(建议)，idea(想法)，reason(理由)等。表语从句对主句主语进行阐明、解释，使主语的内容具体化。The trouble is (that) she has lost his money. 麻烦的事是她丢了钱。The question is whether we need more ice cream.问题是我们与否还需要某些冰淇淋。The problem was that it was too valuable

8、 for everyday use.问题是它作为平常之用太贵重了。What she couldnt understand was that fewer and fewer students showed interest in her lessons. 我们不能理解越来越少的学生对她的课不感爱好。2.由关系代词引导的表语从句。关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等引导表语从句，在句中作主语、宾语、表语，关系代词不能省略。The question is which of us shoul

9、d go.问题是我们哪一种应当去。The problem was who could do the work.问题是谁能做这项工作。Thats what he is worrying about.那就是她在紧张的事。Thats what we should do.那是我们应当做的。3. 由连词because，as if/as though等引导的表语从句。It looked as if it was going to snow.看起来仿佛要下雪了。Thats because we never thought of it.这是由于我们从未想过此事。It seems as if he didnt

10、know the answer.仿佛她不懂得答案。4.由关系副词引导的表语从句。Go and get your coat. Its where you left it. 去把雨衣拿来。就在你本来放的地方。I had neither a raincoat nor an umbrella. Thats why I got wet through. 我们既没伞也没雨衣，这是我们淋湿的因素。That is how mice ruin many stores of grain every year.那就是老鼠是如何每年损害大量粮食的。That is why she failed to pass the

11、exam. (why 在表语从句中充当因素状语) 那就是她考试不及格的因素。注意： “That is why.”是常用句型， 意为“这就是的因素/因此”， 其中why引导的名词性从句在句中作表语， 该句型一般用于针对前面已经阐明过的因素进行总结，又如： That is why you see this old woman before you know, Jeanne. (前文提到Jeanne对老妇人显得苍老憔悴深感惊讶， 说话人对她讲述了其中的因素之后，用这一句来进行概括)。That is why I came. 这就是我来的因素。下面是两个与“That is why.”形式相似的构造(1)

12、“That is why.”与“That is the reason why.”同义， 只但是从语法构造上讲，“That is the reason why.”中why引导的是个定语从句，将其中的the reason去掉则与“That is why.”构造同样， 例如： That is (the reason) why I cannot agree. 这就是我不能批准的理由。(2)“That is because.”句型中附属连词because引导的名词性从句在此作表语， 这也是个常用句型， 意为“这就是为什么/由于”。“That is because.”与“That is why.”之间的不

13、同在于“That is because.”指因素或理由， “That is why.”则指由于多种因素所导致的后果， 例如：He did not see the film last night. That is because he had to help his little sister with her homework.昨天晚上她没有去看电影， 那是由于她得协助她的妹妹做作业。(第一句话阐明成果， 第二句话阐明因素)He had seen the film before. That is why he did not see it last night.她此前曾看过那部电影， 因此她昨

14、天晚上没有去看。(第一句话阐明因素， 第二句话阐明成果)例题精析：考题1The traditional view is _we sleep because our brain is “programmed” to make us do so. A. when B. why C. whether D. that答案D解析下划线处之后是涉及一种因素状语从句的表语从句，如果看不出它是充当整个句子构造的表语从句将难以把握整个句子的意思。因此，应选择可引导名词性从句且不充当任何成分的that。考题2You are saying that everyone should be equal, and thi

15、s is _ I disagree. A. why B. where C. what D. how答案B解析下划线处的引导词引导系动词is后的表语从句并在该表语从句中充本地点状语(“disagree”属于不及物动词， “I disagree”自身是完整的主谓构造)， 下划线应填入引导词where， 表语从句“where I disagree”的意思是“我不批准之处、 我不批准的地方”。考题3 I drove to Zhuhai for the air show last week. Is that _ you had a few days off? A. why B. when C. what

16、 D. where答案A解析下划线处的引导词引导与系动词is连用的表语从句并在该表语从句中充当因素状语，下划线应填入表达“因此”(指因某种因素所导致的成果)的引导词why。考题4_ she couldnt understand was _ fewer and fewer students showed interest in her lessons. A. What; why B. That; what C. What; because D. Why; that答案 A解析 第一种下划线处的引导词引导主语从句并在该主语从句中充当宾语， 特指她所不理解的事情， 应填入关系代词型的引导词what；

17、 第二个下划线处表达“因此”(指因某种因素所导致的后果， 由why引导相应的名词性从句)而不是“为什么”(指因素、 理由， 由because引导相应的名词性从句)， 应填入引导词why。考题5 _ made the school proud was _ more than 90% of the students had been admitted to key universities. A. What; because B. What; that C. That; what D. That; because答案 B解析 第一种下划线处的引导词引导主语从句并在该主语从句中充当主语， 特指令校方

18、骄傲的事情， 应选用关系代词型的引导词what； 第二个下划线处引导表语从句表达因素、 理由， 应由that引导相应的名词性从句。考题6 Are you still thinking about yesterdays game? Oh, thats _. A. what makes me feel excited B. whatever I feel excited aboutC. how I feel about it D. when I feel excited答案A解析A选项的意思是“令我感觉激动的事物”； B选项的意思是“我觉得激动的任何事物”； C选项的意思是“我对它感觉的方式”；

19、D选项的意思是“令我感觉激动的时间”。四个选项中A最适合跟代表“game”的主语that相应， 充当表语从句。， 它们与“That is why.”构造之间的关系要可以辨析清晰： 二、注意：1. 表语从句一定要用陈述语序。False: The question is when can he arrive at the hotel.Right: The question is when he can arrive at the hotel.2. 不可以用if，而用whether 连接表语从句(as if 例外）。1.引导宾语从句时可以互换if/whether 2.位于介词后要用whether，3

20、.位于句首时要用whether 4.引导表语从句，主语从句，同位语从句时要用whetherFalse: The question is if the enemy is marching towards us.Right: The question is whether the enemy is marching towards us.Right: It looked as if he had understood this question.3. 不像宾语从句，在有表语从句的复合句中，主句时态和从句时态可以不一致。Right: The question is who will travel with me to Beijing tomorrow.Right: The question is why he cried yesterday.4. that在表语从句中不可以省掉。 Step III Homework1. 课本练习 21页Ex3 综合伙业本；Ex4 口头检查作业2. 同步练习 53页 语法过关Ex I&II3. 学时分层111页 完毕句子4,5课后反思：
