Section Ⅱ　Learning About Language

表语从句

Ⅰ．用括号内所给词的适当形式填写下面教材中的句子，并体会它们的语法特征。

1．(教材P2) As a young doctor, John Snow became   frustrated  (frustrate) because no one knew how to prevent or treat cholera．

2．(教材P2)One theory was   that   bad air caused the disease．

3．(教材P2) The other was   that   cholera was caused by an infection from germs in food or water．

4．(教材P2)It seemed   that   the woman liked the water from the pump so much that she had it delivered to her house every day．

5．(教材P3)The truth was   that   the water from the Broad Street pump had been infected by waste．

6．That's   why   we've given you the letter．

Ⅱ．根据以上例句填空。

1．句1中系动词became后接  形容词  作表语；句2、3、4、5中作表语的是  从句  。

2．句2、3、4、5中的连接词  that  在句中起连接作用，没有含义。

3．句6中引导  表语从句  的连词有一定的含义，意为“  为什么  ”。

在主从复合句中充当表语的从句称为表语从句。它常位于系动词之后，用来说明主语是什么或怎么样。

一、表语从句的引导词

(一)从属连词that/whether引导的表语从句

that和whether在表语从句中不作任何成分，不可省略，that无实义，但whether仍保留“是否”的意义。

►My suggestion is that we should tell him．

我的建议是我们应该告诉他。

►The question remains whether they will be able to help us．问题是他们是否会帮助我们。

[提示] if不能引导表语从句。

(3)What he wants to know is   whether   we can finish our work by tomorrow morning．

(二)连接代词引导的表语从句

连接代词what(ever), which(ever), who(ever), whom(ever), whose等引导表语从句时，本身有意义，除了在句中起连接作用外，还在从句中充当主语、宾语、表语、定语等成分。

►The problem is who should be responsible for the task．问题是谁应该为这项工作负责。

►Motivation is what you need most to do a good job．

动机是你做好工作最需要的东西。

►What puzzled me was which book I should choose．使我困惑不解的是我该选哪本书。

(2)The problem is   who   is really fit for the hard job．

(3)The problem is   who   can take the place of Jim．

(三)连接副词引导的表语从句

连接副词when, where, why, how等引导表语从句时，除在句中起连接作用外，在从句中往往作状语(时间、地点、原因、方式)。

►The last time we had great fun was when we were visiting the Water Park．

我们上一次玩得很开心是游览水上公园的时候。

►Sara was caught in a traffic jam this morning．That is why she was late for school．萨拉今天早上遇到了堵车，那就是她上课迟到的原因。
