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.

表语从句讲解
一．定义： 表语从句就是用一个句子作为表语。位于系动词之后，说明主语身份，特征，属性或状态。比较： The problem is puzzling. 主语连系动词形容词作表语 The problem is when we can get a pay rise. 主语连系动词一个句子作表语---表语从句 二、系动词的分类（了解哪些词为系动词） 系动词有表示状态的；有表示状态变化的。 表示状态的有： 1）be, seem ,appear 等。 2）look ,sound ,feel ,taste ,smell 等，由感官动词变化而来。意思为“看（听、摸、尝、闻）起来”。 Mr. Li looks quite young. 李先生看起来很年轻。 3）stand ,keep ,prove ,remain 等由不及物动词转化而来。 The machine has been standing idle. 这台机器一直闲着不用。 2.表示状态变化的： become ,get ,grow, fall, turn等 He has fallen ill. 他已经病倒了。 三连接表语从句与主句的关系词主要有三类：
1. 从属连词：that（无有词义）, whether（是否,if （是否） 2. 关系代词：who（谁，主格）, whom（谁，宾格）,whose谁的，所有格）, what（什么）,which（哪个，哪些） 3. 关系副词：when（什么时候）where（什么地方）why（为什么）, how（怎样）例如： The fact is that we have lost the game. 事实是我们已经输了这场比赛。 That’s just what I want. 这正是我想要的。 This is where our problem lies. 这就是我们的问题所在。 That is why he didn’t come to the meeting.那就是他为什么不到会的原因。 It looks as if it is going to rain. 看上去天要下雨了。 It is because you eat too much那是因为你吃得太多了。 The reason why he was late was that he missed the train by one minute this morning （当主语是reason时，表语从句要用that引导而不是because） 另外，与其他名词从句有所不同的是as, as if/though, because也可用来引导表语从句.如： He looked just as he had looked ten years before.他看起来还与十年前一样。 She seems as if she had done a great thing.她看起来好像做了一件大事。 It is because you eat too much.那是因为你吃得太多了。 【注意】because可引导表语从句，但与之同义的since, as, for等也不用于引导表语从句。
