 在被动句中,主语是动作的承受者,它主要用于强调动作的承受者或因为动作的执行者难以说出或不必说出时。我们在学习运用它时,应注意以下两个方面:


一、掌握被动语态的一般结构
被动语态基本形式为:助动词be +过去分词。助动词be有时态、人称和数的变化,我们可以通过be的不同变化形式推出各种时态的被动语态形式。如:
The film is being shown now.
电影正在放映。(现在进行时的被动语态)
Dr 1. Smith had been mentally 2 disturbed by his long years alone in prison.
多年孤独的监狱生活使史密斯医生的精神受到了刺激。(过去完成时的被动语态)
二、掌握几种特殊的被动语态结构
1. 带情态动词的被动结构。其形式为:情态动词+ be +过去分词。
The baby should be taken good care of by the baby-sitter.
婴儿应该由临时保姆好好照看。
2. 当使役动词have, make, get以及感官动词see, watch, notice, hear, feel, observe等后面的不定式作宾语补足语时,在主动结构中不定式to要省略,但变为被动结构时,要加to。
Someone saw a stranger walk into the building.
有人看见一个陌生人走进了大楼。
变为被动句为:A stranger was seen to walk into the building.
3. 非谓语动词的被动语态。动词-ing形式及不定式 to do 也有被动语态。
I don’t like being laughed at in the public.
我不喜欢当众被人嘲笑。
What is to be done next?
下一步要做什么?
4. 短语动词的被动语态。
有些相当于及物动词的动词词组,如“动词+介词”、“动词+副词”等,也可以用于被动结构,但要把它们看作一个整体,不能分开,其中的介词或副词也不能省略。
Women were looked down upon in the old society.
妇女在旧社会被人看不起。

n.医生,大夫;博士(缩)(= Doctor)
  • Dr.Williams instructs us in botany.威廉博士教我们植物学。
  • The ward of the hospital is in the charge of Dr.Green.医院的这间病房由格林医生负责。
adv.精神上,理智上,在心中
