课文 & 语法讲解

语法讲解 （复习L10被动语态）

1、被动语态

• 形式

be + done
be: 被动的时间
done: 表示被动的动作

• 例句

CN	Eng
他每天被打	He is beaten every day.
他昨天被打了	He was beaten every day
他明天将要被打	He will be beaten every day
他现在正在被打	He is being beaten
他现在已经被打了	He have been beaten

课文

• 1、Dan Robinson has been worried all week.

worried 担心

has been 现在完成时态 (L4、L5)

• 2、Last Tuesday he received a letter from the local police.

• 3、In the letter he was asked to call at the station.

call at + 地点
call on + 人
visit + 人/物

• 4、Dan wondered why he was wanted by the police

被动语态: was wanted 被要求

• 5、At the station, he was told by a smiling policeman that his bicycle had been found。

doing可以修饰名词： smiling 

was told 被告诉，过去时
had been found 被告诉之前，已经被找到了，过去完成时

• 6、Five days ago, the policeman told him, the bicycle was picked up in a small village four hundred miles away.

pick up 是偶然被找到的
was picked up 被捡到，被动语态

为什么第5句，为什么用过去完成时？第6句使用过去时呢？
因为第5句，一个句子有明显一前一后，可以强调，所以用了过去完成时

• 7、It is now being sent to his home by train.

因为有now, 所以要用现在进行时被动语态.

• 8、Dan was most surprised when he heard the news.

两种形式看待：
  was most surprised 被动语态
  be + 形容词

• 9、...because he never expected the bicycle to be found.

to do 是要跟expected的，不定式也可以被动

• 10、It ·was stolen` twenty years ago....
