被动语态复习-[Thepassivevoice].pptVIP

被动语态复习：（The passive voice);注：只有及物动词才可能有动作的承受者，所以只有及物动词才可用于被动语态。;一般现在时：is / are + -ed 一般过去时：was / were + -ed 一般将来时：will be + -ed 过去将来时：would be + -ed 现在进行时：is / are being + -ed 过去进行时：was / were being + -ed 现在完成时：have(has) been + -ed 过去完成时：had been + ed;被动态的应用范围：有的时候人们说话时偏重于事情本身而不是做事情的人，比如：这项计划制定得很完善；This plan has been made perfectly. 有的时候不可能、不必要将从事某种动作的人说出来，比如：这里啥时新出了一家商店？When was this newly built shop operated here? 在这样的情境下都需用到被动态。;被动态中若出现情态动词，助动词 be 无需变化。 1. Wood can be used to make paper. 2. Who should be praised? 3. These books must not be taken out of the room. 4. Chocolate may be sent to him as a present. 5. He will be sent to work in the North-east.;被动语态各种时态练习：（请注意以下各句中动词形式，尤其是助动词 be 的变化形式。;;give, lend, offer, ask等需要两个连带成分，一个指人，另一个指事物，如：Mother gave me a tie as my birthday present. 被动态既可以用“人”作为述说对象，也可以以“物”作为述说对象： A: I was given a tie by my mother as my birthday present. B: A tie was given (to) me as my birthday present. 这样的句子多用“人”作为述说对象。;动词词组用于被动态： A：保留介词或副词： This film is often talked about. The baby was looked after by Aunt Lucy. All your compositions must be handed in after class. This work shouldn’t be given up.;B: take care of, pay attention to, set fire to, make use of, take hold of 等词组内含有名词的词组，有两种变化：其一，将其看作一个词，将其后的连带成份作为述说的对象： The patient must be taken good care of. 或者将该词组内部的名词作为述说对象： Good care must be taken of the patient. 在这种情况下多数采用上一句英文的说法。请变化下面句子：;1. You should pay more attention to your reading. 2. Someone had set fire to the house. 3. We must make full use of these natural resources. 4. You can take notice of the key words when reading.;练习;用被动语态改换下列各句：;;7. You mustn’t take those books out of the reading-room.;10. They are serving breakfast between six and nine o’clock.;11. He gave me a present.;13. You must pay attention to your writing.;14. We must take good care of this sick little girl.
