高中英语人教版选择性必修第二册unit 1 Grammar表语从句(ThePredicative Clause)一、表语从句的定义：表语从句就是用一个句子作为表语，放在连系动词之后，充当复合句中的表语，用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. 主语连系动词一个句子作表语一表语从句二、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、表语从句的用法.可按表语从句的连系动词有：1).最常用连系动词：be(am; is/was; are/were)o一般在句子中译成：“ 日”7E ...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。

用法注意：在英语中，系动词一般只有一般现在时和一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无：Two years later, he became a teacher.但Two years later, he turned teacher.另外，g。

表变化时一般指事情向消极、不好的方面转化。

3).所谓“感官动词”:look; sound; ta ste; smell; fbeL般它们在句子中译成:“・・・起来; ...上去”。

此类系动词为高考高频词。

The food tasted good.食物尝起来很香。
