动词短语构成的被动语态应注意的个问题
一般情况下,只有及物动词才能跟宾语,而不及物动词不能跟宾语,所以只有及物动词才有被动语态,不及物动词则没有被动语态。但有些不及物动词后面跟上介词或副词后,变成一个动词短语,相当于一个及物动词,因此就可以有被动语态。
the nurses in this hospital look after the patients very well.
-- the patients are well looked after by the nurses in this hospital. 病人在这所医院里被护士们照料得很周到。
they have put off the meeting till next saturday.
-- the meeting has been put off till next saturday. 会议已推迟到下周六了。
注意:
在初中英语语法练习题使用被动语态时,千万不要遗漏句末的介词或副词。
such a bad habit should be got rid of. 这样的坏习惯应该改掉。
all the important matters have now been attended to. 所有重要的事情都得到了处理。
双重被动结构
双重被动结构指的是句中谓语动词和其后的不定式均为被动结构,句子的主语既是谓语动词的承受者,同时又是不定式动作的承受者。
they asked us to discuss the problem at once.
-- we were asked to discuss the problem at once.
-- the problem was asked to be discussed at once. 这个问题被要求立刻讨论。(双重被动)
she offered to buy a recorder for me.
-- a recorder was offered to be bought for me. 有人提出要帮我买一台录音机。(双重被动)
the teacher ordered that we should take the desk away.
-- the desk was ordered to be taken away. 课桌被要求搬走。(双重被动)
下列句子变成被动语态时,要用with,不用by
smoke filled the meeting room. 烟充满了会议室。
the meeting room was filled with smoke. 会议室里充满了烟。
a cloth covered the table. 一块布把桌子罩了起来。
the table was covered with a cloth. 桌子上铺着一块布。
进行词汇教学,首先要明确词汇教学的内容。不同的外语学习者,学习程度、学习动机和目的、学习英语记单词方法任务等都有差异。因此,词汇教学内容应具有针对性和选择性。
把意义相同或相近的同义词归纳在一起记,比较它们的异同,进行词汇分析,可以加深印象,容易记牢。
  比如:also,too也、再、又、并且;arms,weapon武器、兵器。
  前两个同义词不同的地方在于:日常用语中too比also用得更多。also一般放在句子中间,too总是放在句末。我是单词王可以比较:she also knows something ofpoetry.(她略知诗词。)i’u go there,too.(我也要到那里去。)
  后两个同义词不同的地方是:~fltns指专为打仗而造的兵器,如刀、枪、剑、戟、炮、炸弹等,而weapon的意义比较广泛,可指人们的思想武器、植物的芒刺、动物的瓜牙和一切自卫用的东西。
在记忆住一个单词的同时,我们可以联想记忆多个单词,这种记忆法使我们在生活学习的间隙也可以记忆住更多的单词。这种记忆法,更是可以方便的检查自己的单词记忆量以及牢固程度。
