Lesson 48 Did you want to tell me something?Dentists always ask questions when it is impossible for you to answer. My dentist had just pulled out one of my teeth and had told me to rest for a while. I tried to say something, but my mouth was full of cotton-wool. He knew I collected match boxes and asked me whether my collection was growing. He then asked me how my brother was and whether I liked my new job in London. In answer to these questions I either nodded or made strange noises. Meanwhile, my tongue was busy searching out the hole where the tooth had been. I suddenly felt very worried, but could not say anything. When the dentist at last removed the cotton-wool from my mouth, I was able to tell him that he had pulled out the wrong tooth.

任务配置：L0+L4

【课文讲解】 

1、Dentists always ask questions when it is impossible for you to answer.

impossible通常不以人作主语，而以不定式或从句作主语： 

  It is impossible for him to help you. =It is impossible that he will help you.

2、In answer to these questions I either nodded or made strange noises.

in answer to…     作为对……的回答；响应……的请求  

  In answer to my request, he wrote a letter to George.    应我的请求，他给乔治写了封信。 

in return for      作为对……的报答 

3、Meanwhile, my tongue was busy searching out the hole where the tooth had been.

meanwihile      在此期间，与此同时 

  He won’t come until ten o’clock. Meanwhile you can have a rest.

  Mary was talking to me about her new dress. Meanwhile I was thinking about something else.

where =  介词 + which

That is the house which I lived in.     这是我住的房子 

=That is the house where I lived.

where称为关系副词,另外还有when也是关系副词 

This is the river where I swim.  （where作定语从句的标志,修饰前面的river） 

The tooth had been in the hole. (in the hole = where)

4、When the dentist at last removed the cotton wool from my mouth, I was able to tell him that  

he had pulled out the wrong tooth.

remove可以表示“拿去，除去，去掉”，通常结构为“remove +名词 +from”，也可以单独使用： 

I’ve removed that picture from the wall.

Please remove your hat.
