赤峰市华夏职业学校表格教案(二)
赤峰市华夏职业学校表格教案(三) 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）。 引导宾语从句时可以互换if/whether 位于介词后要用whether 位于句首时要用whether 引导表语从句，主语从句，同位语从句时要用whether False: 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。 注意：“That is why...”是常用句型，意为“这就是……的原因/因此……”，其中why引导的名词性从句在句中作表语，该句型通常用于针对前面已经说明过的原因进行总结，又如： That is why you see this old woman before you know, Jeanne. 珍妮，这就是现在这个老太婆出现在你面前的原因。(前文提到Jeanne对老妇人显得苍老憔悴深感诧异，说话人对她讲述了其中的原因之后，用这一句来进行概括)。// That is why I came. 这就是我来的原因。 下面是两个与“That is why...”形式相似的结构，它们与“That is why...”结构之间的关系要能够辨析清楚： (1)“That is why...”与“That is the reason why...”同义，只不过从语法结构上讲，“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...”结构一样，例如： That is (the reason) why I cannot agree. 这就是我不能同意的理由。 (2)“That is because...”句型中从属连词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……/因为……”。“That is because...”与“That is why...”之间的不同在于“That is because...”指原因或理由，“That is why...”则指由于各种原因所造成的后果，例如：He did not see the film last night. That is because he had to help his little sister with her homework.昨天晚上他没有去看电影，那是因为他得帮助他的妹妹做作业。(第一句话说明结果，第二句话说明原因) He had seen the film before. That is why he did not see it last night.他以前曾看过那部电影，因此他昨天晚上没有去看。(第一句话说明原因，第二句话说明结果) ［考题1］The 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］下划线处之后是包含一个原因状语从句的表语从句，如果看不出它是充当整个句子结构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2］ You are saying that everyone should be equal, and this is ____ I disagree. (2004) 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当地点状语(“disagree”属于不及物动词，“I disagree”本身是完整的主谓结构)，下划线应填入引导词where，表语从句“where I disagree”的意思是“我不同意之处、我不同意的地方”。 ［考题3］— I drove to Zhuhai for the air show last week. — Is that ____ you had a few days off (1999) A. why B. when C. what 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原因状语，下划线应填入表示“因此……”(指因某种原因所造成的结果)的引导词why。 ［考题4］____ she couldn’t understand was ____ fewer and fewer students showe d interest in her lessons.
15级计算机班英语 表语从句讲解 概念：表语从句是在复合句中作表语的名词性从句。 放在系动词之后，一般结构是“主语+系动词+表语从句” 可以接表语从句的连系动词有be, look, remai n, seem 等。 ★The trouble is that we are short of mon ey. 困难是我们资金短缺。 ★ That is why stone walls are used in stead of fen ces around NewE ngla nd fields.这就是为什么在新英格兰用石头墙而不用栅栏的原因。 ★At that time, it seemedas if I could n't think of the right word an yhow. 当时,我似乎怎么也想不出一个恰当的字眼来。 引导表语从句的词： 从属连词that、whether、as though、as if （That引导表语从句时，在口语中，间或可以省略。） 关系代词who, what, which, whom,whose, whatever, whoever, whomever, whichever 等； 关系畐【J词when, where, why, how, however, whenever, wherever 等。 探由从属连词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、“是否”。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（结果），chance（可能性），suggestion（建议），idea（想法），reason（理由）等。表语从句对主句主语进行说明、解释，使主语的内容具体化。 例如： ★The trouble is （that） she has lost his mon ey. 麻烦的事是他丢了钱。 ★The questi on is whether we n eed more ice cream. 问题是我们是否还需要 一些冰淇淋。 ★The problem was that it was too valuable for everyday use. 问题是它作为日常之用太贵重了。 ★What she couldn ' t understand was that fewer and fewer students showed in terest in her lesso ns. 我们不能理解越来越少的学生对他的课不感兴趣。 探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。例如： ★The questi on is which of us should go. 问题是我们哪一个应该去。 ★The problem was who could do the work. 问题是谁能做这项工作。 ★That's what he is worryi ng about. 那就是他在担心的事。 ★That's what we should do. 那是我们应该做的。 ※由关系副词引导的表语从句。 关系副词when, where, how, why 除在句子起连接作用外，在从句中还充 当时间，地点，方式或原因状语，本身具有词义。

Step(1) Warming up and Lead in Step(2) talking about (一) 表语从句 The Object Clause 在句子中起表语作用的从句叫做表语从句，位于主句系动词的后面。表语从句的引导词和主语从句的引导词相同。也是名词性从句的一种。 （二）不同引导词引导的表语从句 1、由从属连词that 引导的表语从句 The fact is that he doesn’t really try. （努力） The trouble is that I have lost his address. 引导表语从句的that 通常不省略，但在口语或非正式文体中有时也可省略： The trouble is (that) he is ill. 糟糕的是他病了。 2、由连词whether 引导 The question is whether the film is worth seeing. 问题是这部电影是否值得看。 【注意】whether 可引导表语从句，但与之同义的if 却通常不用于引导表语从句。 Greeting s Ask questions Enlighten the Students to answer questions Greetings Listen carefully Look at the screen Think over and answer questions 启 发 引 导 原 则 赤峰市华夏职业学校表格教案(二)

表语从句 1．定义：用作表语的从句叫做表语从句。 2．引导表语从句的关联词的种类： (1)从属连词that。在从句中不做成分。如：The trouble is that I have lost his address.麻烦是 我把他的地址丢了。The reason was that he was late for school.

The question is how he did it. (11)连词because可引导表语从句。如： (12)I think it is because you are doing too much. 我想这是因为你做得太多。 It's just because he doesn't know her. (13)T hat's because he didn't understand me. 那是因为他没有理解我.(That's because...强调原因) (14)T hat's why he got angry with me.那正是他对我生气的原因。(That's why...强调结果) (15)在一些表示“建议、劝说、命令”的名词后面的表语从句中，谓语动词用虚拟语气。should+动词原形表示，should可省略。如： (16)M y suggestion is that we (should) start early tomorrow. 我的建议是我们明天一早就出发。
