33、im a present for his birthday. 可改为 He was given a present by his mother for his birthday.3) 当“动词+宾语+宾语补足语”结构变为被动语态时，将宾语变为被动结构中的主语，其余不动。例Someone caught the boy smoking a cigarette. 可改为The boy was caught smoking a cigarette.4）在使役动词have, make, get以及感官动词see, watch, notice, hear, feel, observe等后面不定式作宾语补语

34、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。例Someone saw a stranger walk into the building. 可改为A stranger was seen to walk into the building.5) 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。例The meeting is to be put off till Friday.非谓语动词的被动语态v.+ing 形式及不定式 to do 也有被动语态(一般时态和完成时态) 。例I don

35、t like being laughed at in the public.It is said that+从句及其他类似句型一些表示“据说”或“相信”的动词如believe, consider, expect, report, say, suppose, think等可以用于句型“Itbe过去分词that从句”或“主语be过去分词to do sth.”。有：It is said that 据说,It is reported that据报道，It is believed that大家相信，It is hoped that大家希望，It is well known that众所周知，It is

36、thought that大家认为，It is suggested that据建议。例It is said that the boy has passed the national exam.（The boy is said to have passed the national exam. ）谓语动词的主动形式表示被动意义英语中有很多动词如 break，catch，clean，drive，lock，open，sell，read，write，wash等，当它们被用作不及物动词来描述主语特征时，常用其主动形式 表达被动意义,主语通常是物。例 This kind of cloth washes we

37、ll.注意：主动语态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。试比较：The door wont lock（指门本身有毛病）The door wont be locked（指不会有人来锁门, 指“门没有锁”是人的原因）表示“发生、进行”的不及物动词和短语，如：happen, last, take place, break out, come out, come about, come true, run out, give out, turn out等以主动形式表示被动意义。例 How do the newspapers come out? 这些报纸是如何引出来的呢？系动词

38、没有被动形式, 但有些表示感受、感官的连系动词feel, sound, taste, book, feel等在主系表结构中常以主动形式表示被动意义。例Your reason sounds reasonable.非谓语动词的主动形式表被动意义在need，want，require, bear等词的后面，动名词用主动形式表示被动意义，其含义相当于动词不定式的被动形式。例The house needs repairing（to be repaired）这房子需要修理。形容词worth后面跟动名词的主动形式表示被动含义，但不能跟动词不定式；而worthy后面跟动词不定式的被动形式。例The pictur

39、e-book is well worth reading（The picture-book is very worthy to be read）动词不定式在名词后面作定语，不定式和名词之间有动宾关系时，又和句中另一名词或代词构成主谓关系, 不定式的主动形式表示被动含义。例 I have a lot of things to do this afternoon (to do与things是动宾关系，与I是主谓关系。)试比较：Ill go to the post office. Do you have a letter to be posted? ( 此处用不定式的被动语态作定语表明you不是po

40、st动作的执行者。)在某些“形容词不定式”做表语或宾语补足语的结构中，句子的主语或宾语又是动词不定式的逻辑宾语时，这时常用不定式的主动形式表达被动意义。这些形容词有nice，easy，fit，hard，difficult，important，impossible，pleasant，interesting等。例This problem is difficult to work out .（可看作to work out省略了for me）.在too to结构中，不定式前面可加逻辑主语，所以应用主动形式表示被动意义。例This book is too expensive (for me) to bu

41、y.在there be句型中，当动词不定式修饰名词作定语时，不定式用主动式作定语，重点在人，用被动形式作定语，重点在物。例There is no time to lose（to be lost）（用 to lose可看成for us to lose；用to be lost，谁 lost time不明确。）在be to do结构中的一些不定式通常应用主动表主动, 被动表被动。然而,由于古英语的影响,下列动词rent, blame, let等仍用不定式的主动形式表示被动意义。例 Who is to blame for starting the fire?介词in, on, under等+名词构成介

42、词短语表被动意义表示方位的介词与含动作意义的名词合用，含被动之义，其意义相当于该名词相应动词的被动形式，名词前一般不用冠词。 “under +名词”结构，表示“某事在进行中”。常见的有：under control（受控制）, under treatment（在治疗中）, under repair（在修理中）, under discussion（在讨论中）, under construction（在施工中）。例The building is under construction( is being constructed).“beyond+名词”结构，“出乎胜过、范围、限度”。常见的有：beyo

43、nd belief (令人难以置信)， beyond ones reach（鞭长莫及），beyond ones control（无法控制），beyond our hope 我们的成功始料不及。例The rumor is beyond belief（=cant be believed）“above+名词”结构, 表示“(品质、行为、能力等) 超过、高于”。例His honest character is above all praise=His honest character cannot be praised enough“for+名词”结构，表示 “适于、 为着”。如：for sale(出

44、售), for rent（出租）等。例That house is for sale. (= The house is to be sold).“in+名词”结构 ，表示“在过程中或范围内”常见的有：in print（在印刷中），in sight(在视野范围内)，等。例The book is not yet in print(=is not yet printed) “on+名词”结构, 表示“在从事 中”。常见的有：on sale(出售)，on show（展出）, on trial（受审）。例Today some treasures are on show in the museum (= a

45、re being showed).“out of+名词”结构 ； 表示 “超出 之外“，常见的有：out of control (控制不了)，out of sight （超出视线之外），out of ones reach(够不着), out of fashion(不流行)等。例 The plane was out of control (cant be controlled) 。“within+名词”结构，“在内、不超过”。例He took two days off within the teachers permission5.
