主动表被动的动词

主动表被动的动词 主动表被动的动词 某些动词的主动形式表被动含义 英语中有很多动词如act，break，catch，cut，clean，cook, drive，draw， let，lock，open，sell，read，write，wash，wear等，当它们被用作不及物动词来描述主语特征时，其主动形式常用来表达被动含义。另外，像 owe (There are still ten dollars owing. )，beat，cook，bake(The cake baked too long.)，print，build，make等，有时可以用主动形式表达被动含义。如: This kind of radio doesn't sell well(这种收音机不太畅销。 The shop opens at eight o'clock(这个商店八点开门。 The pipe does not draw well(这烟斗不太通畅。 These plays act wonderfully(这些剧演得好。 Kate's book reads like an interesting novel(凯特的这本书读起来像本有趣的小说。 注意:主动表被动强调的是主语的特征，而被动语态则强调外界作用造成的影响。如: The door won't lock(门锁不上。(指门本身有毛病) The door won't be locked(门不会被锁上。(指不会有人来锁门) His novels sell easily(他的小说销路好。(指小说本身内容好) His novels are sold easily(他的小说容易销售。(主要强调外界对小说的需求量大) 现在完成时的标志 小结 学校三防设施建设情况幼儿园教研工作小结高血压知识讲座小结防范电信网络诈骗宣传幼儿园师德小结 1. already, yet, for, since, just these days, ever, never, today, this week (month), lately, recently, in the past few days, during/in the last/past/recent two weeks…, since yesterday, since two days ago, since 2002, for a long time, for a month, so far, up to now, till (until) now, often, once, twice, three times… 2. 1)It has been/is about five months since I heard from him.

I must admit I _____ her to _____ _____ us. 请欣赏 I pormised to have done him a favor several days ago. I had pormised to do him a favor several days ago. I hoped to have finished by 12. I had hoped to finish by 12. We wished to have put out the fire in thirty minutes. We had wished to put out the fire in thirty minutes.) 我们本打算半小时就把火扑灭的。(结果没有) 3> was/were to have done 请欣赏 You were to have arrived there early that day. 那天你们应该早点儿到那。(但你们晚到了。) I was to have helped him then，but I was too busy. 那时我本想帮他的忙，可我太忙了。(未帮他的忙)。 是啊，上述三种句式均表示过去想做而未做成的事情。 不定式的完成进行体 二、动词 动词不定式的完成进行体表示不定式的动作发生在谓语动词之前，并一直在进行着。其结构与不定式的完成体类似。如: He is said to have been translating Lu Xun’s works into English. 据说他一直在把鲁迅的作品译成英文。(现仍然在译) He seems to have been teaching in that school for ten years. 他似乎已经在那所学校教了十年书了。(强调继续教) The kind-hearted millionaire is very happy to have been helping the disabled. 那位善良的富翁一直在帮助残疾人，并为此感到非常高兴。(仍在帮助) We supposed to have been living here till our children grew up. 我们原以为可以在这一直呆下去，直到我们的孩子长大。(但我们家搬了) 三、动词不定时完成体的被动式 当主语与不定式的动词有被动关系，且不定式所表示的动作又先于谓语动词动作发生时，动词不定式就要用完成体的被动式。例如: The book is said to have been translated into many languages. 据说那本书已被译成了多种语言。 The oranges were thought to have all been sold out. 人们认为桔子已经全部卖光了。 He is very sad to have lost four relatives in the earthquake. 他为这次地震中失去了四位亲人而感到十分痛心。 一些特殊句型中的过去完成时: 1〕"It/This/That was the first /only(second/third…)time+that从句(过去完成时)" 2〕"It/This/That was the +最高级… + that从句(过去完成时)" 3〕by( the end of )+过去时间,句中谓语用过去完成时 ?We had learnt 3,000 words by the end of last term. ?By 8:00a.m. yesterday, we had arrived the park. 想一想，若by( the end of )+将来时间，从句中用什么时 态呢, 是用下列时态呀: will have done/will have been done 或 would have done/would have been done 4〕by the time+一般过去式,主句中谓语用过去完成时 By the time he came back, we had repaired the machine. 5〕No sooner + had+主语+p.p. +than +一般过去 时/Hardly/ Scarcely/ Barely + had+主语+p.p. + when +一般过去时 ?No sooner had he gone to the garden than his son went to play with his classmates. ?Hardly had he heard the news when he cried.
