动词不定式被动语态讲解 Prepared on 24 November 2020
Book7unit2动词不定式被动语态形
一、复习各种时态的被动语态
★被动语态的基本结构:be+done
(以thebook,publish为例)
一般现在/过去时:
Thebook is/waspublished.
一般/过去将来时:
Thebook will/wouldbepublished.
Thebook is/wasgoingtobepublished.
现在/过去进行时:
Thebook is/wasbeingpublished.
现在/过去完成时:
Thebook has/hadbeenpublished.
情态动词:
Thebook can/could/may/might…bepublished.
二、不定式的被动式的基础知识:
1)一般式:(not/never)tobedone
2)完成式:(not/never)tohavebeendone(表示不定式动作发生在谓语动词之前)三、▲通常在believe,suppose,say,report等动词构成的句子中可以进行主动语态到被动语态以及被动语态和动词不定式的转换.如:
TheysaythatMikeissickinbed.
=ItissaidthatMikeissickinbed.
=Mikeissaidtobesickinbed.
据说麦克卧床不起.
Peoplebelievethathewaskilled.
=Itisbelievedthathewaskilled.
=Heisbelievedtohavebeenkilled.
大家相信他被杀了.
四、当不定式的逻辑主语是不定式所表示的动作的承受者而非发出者时,不定式一般要采用被动形式(tobedone).
语法功能:
1.作主语:
Itisanhonourforme tobeasked tospeakhere.
2.作宾语:
Sheasked tobesent toworkinXinjiang.
3.构成复合宾语:
Hewantedtheletter tobetyped atonce.
Shedidn’tlikeherself tobepraised likethat.
4.构成复合谓语:
Thebooksarenotallowed tobetakenoutoftheroom.
5.作定语:
Areyougoingtothemeeting tobeheld intheteachers’office
6.作状语:
Shewastooyoung tobeassigned suchwork.
五、不定式有时还可以有完成式的被动式tohavebeendone(表示该动作是发生在主句之前的一个被动动作),在句中作主语、宾语、定语,或者构成复合宾语、复合谓语等,如:
Itisagoodthingforhim tohavebeencriticized.(主语)
Shepreferred tohavebeengiven heavierworktodo.(宾语))
Hethoughtitanhonour tohavebeeninvited totheparty.(复合宾语)
Thebookissaid tohavebeentranslated intomanylanguages.(复合谓语)
Shewasthefirstwoman tohavebeenelected tosuchapost.(定语)
六、不定式的主动形式表示被动
1.Therebe结构中,用不定式的主动和被动式来修饰主语,区别不大。(多用主动形式) 例如:Thereisalotofwork todo/tobedone.
Thereisnotime tolose/tobelost.
译:没有什么可担心的。
________________________________
Thereisnothingtoworryabout.
注意以下两点:
(1)如果不定式结构加了"forsb."表示的逻辑主语时Therearestillmanyquestionsforustodiscuss.(us与discuss主谓关系,用主动todiscuss) Therearealotofreasonsforthebooktobepublished.
(thebook与publish是动宾关系,用被动tobepublished)
(2)某些动词(do,see)的不定式特殊用法时,两种形式所表示的意思不同。比较:Thereisnothingtodonow.(Wehavenothingtodonow.)
Thereisnothingtobedonenow.(Wecandonothingnow.)
Thereisnothingtosee.(Nothingisworthseeing.)
Thereisnothingtobeseen.(Nothingisthereatall.)
2.在“主语+be+adj+todo”句型中:常见的adj有hard,amusing,interesting,cheap,difficult,dangerous,easy,nice,important,. Thatquestionisdifficulttoanswer.
Heisanimpossiblepersontoworkwith.
但若要强调句中的受事者,也可用不定式的被动式:Thehandwritingisdifficulttoberead.
★注意:
如果动词为不及物动词,则要注意介词的搭配。
Johnisdifficulttodealwith.
分析:_________(动)----________(宾))
