1、中英语人教版选择性必修第二册unit 1 Grammar表语从句 (The Predicative Clause) 、表语从句的定义：表语从句就是个句作为表语， 放在连系动词之后， 充当复合句中的表语， 来说明主语是什么或者怎么样。 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.主语连系动词个句作表语-表语从句 、表语从句的构成： 系动词+ 引导词+简单句What I want to say is that I am tired.三、表语从句的法1.可接表语从句的连系动词有:1).
2、最常连系动词： be(am; is/was; are/were)。般在句中译成：“是 ”China is no longer what she used to be.2). 表变化的系动词：get; turn; go; fall; become; grow; come; run。法注意：在英语中， 系动词般只有般现在时和般过去时两种时态变化形式， 没有其他时态变化形式。但表变化的这类 系动词除外， 它们有各种时态变化。It is becoming colder and colder. The food has gone bad.此处还需注意的是become和turn后接表职业的名词时冠词的有：
3、Two years later, he became a teacher.但Two years later, he turned teacher.另外， go表变化时般指事情向消极、不好的转化。3). 所谓“感官动词”:look; sound; ta ste; smell; feel般它们在句中译成：“起来； 上去”。此类系动词为考频词。The food tasted good. 物尝起来很。He looked sadly at the picture. / She looked sad after hearing the news.Tom tasted the food and it tas
4、ted good.4). 表状态的系动词： keep; stay; remain; 般在句中译成：“依然是；保持”She remains loyal to her father despite his cruelty towards her.What a lovely day today! I love fine weather and I hope it will stay fine for some days.Much remains to be done.5). 表像系动词：seem; appear。般在句中译成：“看起来像”、“似乎”、“好像”。这两个动词有个共同的特点， 即如果要表达
5、时态的变化， 需要后接不定式来完成。He seemed to have caught cold.It appears to me that he wants to teach us all he has.When Father came in, Tom seemed to be eating something.另外此处句型转换也要牢记：It seemed that he had caught cold.When Father came in, it seemed that Tom was eating something.6). 终系动词： prove;turn out。般在句中译成：“证实
6、、证明、结果为 ”He proved (to be) right. / The experiment turned out successful.2.引导表语从句的关联词的种类：1)从属连词that , that在表语从句中不充当任何句成分， 也没有任何意义。The trouble is that I have lost his address.2)从属连词whether, as, as if /as though引导的表语从句， 有的含义， 但在从句中并不充当语法成分。3)because, why引导的表语从句， 有的含义， 但在从句中并不充当语法成分。Thats why he didnt
7、understand me.I think it is because you are doing too much.注意：“That/It is because.”与“That/It is why.”之间的不同在于“That/It is because.”指原因或理由;“That/It is why.”则指由于 各种原因所造成的后果。He did not see the film last night. That is because he had to help his little sister with her homework. He had seen the film before
8、. That is why he did not see it last night.4)连接代词who, whom, whose, what, which; 连接副词where, when, how , why它们分5)使虚拟语的表语从句在表建议、劝告、命令等含义的名词后的表语从句， 谓语动词需“should+动词原形”表， should可省略。常见的词有： advice, suggestion, order, proposal, plan, idea 等。My suggestion is that we (should) start early tomorrow .3. 注意：1) 表语从
9、句定要陈述语序。False: The question is when can he arrive at the hotel.Right: The question is when he can arrive at the hotel.2) 在有表语从句的复合句中， 主句时态和从句时态可以不致。Right: The question is who will travel with me to Beijing tomorrow .Right: The question is why he cried yesterday.3) that在表语从句中般在书语中不可以省， 但在语中可以省略。 The
10、idea is (that) we shall go to picnic this week.4)“That is why.”与“That is the reason why.”同义， 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.”结构样。That is (the reason) why I cannot agree.5). 当主语为The reason(why )时， 表语从句的引导词只能that Right: The reason (why he was late) wa
