ThePresentPerfectPassiveVoice
现在完成时被动语态由”has/have+been+及物动词的过去分词”构成。
使用现在完成时被动语态要注意以下几点:
.只带有一个宾语的动词变为被动语态时,将主动语态的宾语变为被动语态的主语。
例如:
wehavebuiltmanyhousesinthepasttenyears.
→manyhouseshavebeenbuiltinthepasttenyears.
2.带有双宾语的动词,如give,send,bring,take,teach,show,tell,make,sing,write,read,sell,buy,tell,pay,lend,pass,promise等,变为被动语态时,可将其中一个宾语变为主语,另一个保留不动。
例如:
wehavegivenhimthebook.
→Hehasbeengiventhebook.
→Thebookhasbeengiventohim.
3.带有复合宾语的动词变为被动语态时,只能将宾语变为主语,原来的宾补改为主语补足语。
原来省略to的不定式作宾补的,被动语态中要用带to的不定式。
例如:
Ihavetoldthemtohelpyou.→Theyhavebeentoldtohelpyou.
Ihavemadeherworkhard.→Shehasbeenmadetoworkhard.
4.短语动词变为被动语态时,要注意保持短语的完整性,动词后原有的介词或副词不可遗漏。
例如:
Theyhavereferredtothebooks.→Thebookshavebeenreferredto.
Hehasthoughtofawayofdongit.→Awayofdoingithasbeenthoughtof.
.Hundredsofjobs________ifthefactorycloses.(XX全国春招)
A.lose
B.willbelost
c.arelost
D.willlose
[解析]本句的意思是:
如果工厂倒闭,那么将失去数百个工作岗位。
loseajob意为”失业”。
工作将被失去,要用将来时态的被动语态,因此排除答案A、c和D,答案选B。
2.ThemayorofBeijingsaysthatallconstructionworkfortheBeijingolympics________byXX.
A.hasbeencompleted
B.hascompleted
c.willhavebeencompleted
D.willhavecompleted
[解析]宾语从句中主语allconstructionworkfortheBeijingolympics和谓语动词complete之间有被动关系,所以谓语要用被动语态,因此排除选项B和D;byXX暗示谓语要用将来完成时态,因此答案选c。
3.Allthepreparationsforthetask________,andwearereadytostart.
A.completed
B.complete
c.hadbeencompleted
D.havebeencompleted
[解析]本句的意思是:
这项工作的一切准备工作已经就绪,我们只等开始了。
前半句主语和谓语有被动关系,后半句暗示说话是从现在着眼,所以用现在完成时态的被动语态。
答案D。

分小组,讨论它们的共同点。
[要点导航]incommon共有,公用(常与have,own等动词连用,在句中多作状语)。
例如:
Thetwobrothersownthecompanyincommon.
兄弟俩共有这家公司。
Thetwocultures________________________.这两种文化具有许多相同之处。
janeandIhavenothingincommon.
我与简毫无共同之处。
[思维拓展]incommonwith和……一样(作方式状语)。
例如:
,helikesfootball.他和很多其他的男孩一样喜欢足球。
havenothingincommon无共同之处
havelittleincommon几乎无共同之处
havesomethingincommon有一些共同之处
havealotincommon有许多共同之处
以下是从英国国家语料库中精选出来的几个例句:
(1)youknow,Dorothy,youandIhaveonethingincommon.
(2)wejusthadnothingincommonandIcouldn'tcommunicatewithhisdullbusinessfriends.
(3)Isuddenlyfeltwehadalotincommon.
TomandIhavenothingincommon.=I
我和汤姆没有共同之处。
common,ordinary和usual的区别:
common指“共有的,公共的;共同的;常见的”。
例如:
Heistheircommonenemy.他是他们共同的敌人。
Theproblemsarecommontoallsocieties.这些问题是所有社会的通病。
common作“普通的”讲可与ordinary换用。
如“普通人”也可说成commonpeople。
ordinary意为“普通的,平淡无奇的”,指没有什么特别的地方。
例如:
weareallordinarypeople.我们都是普通人。
Heisinordinaryclothes.他穿着平常的衣服。
usual意思是“平常的,通常的,一向的”,含有遵循常规的、习惯性的、一贯如此的意思。
例如:
TeaisconsideredtobetheusualdrinkoftheBritishpeople.
茶被认为是英国人的日常饮料。
Hemadetheusualmistakesthatallbeginnersmake.
他犯的就是那些初学这老犯的错误。
2.Anyway,let’sgobacktomyhistory.无论如何,让我们追溯一下我的历史。
anywayadv.无论如何,反正(句子副词,等于anyhow。
用于转换话题或回到原话题时)。
例如:
Anywayit’sworthtrying.不管怎样,值得试一下。
That’snotmyfault,anyway.反正那不是我的错。
AnywayImustfinishtheworktoday.无论如何,我今天必须完成工作。
[思维拓展]anywayadv.总之(句子副词,用于结束谈话时)。
例如:
Anyway,Imustbegoingnow.总之,我现在得走了。

总之,在诊所治疗三个月后,她完全康复了。
3.Astheyearshavegoneby,Ihavebeenmadesmallerandsmaller.
一年一年过去了,我被制造得越来越小。
此处as引导时间状语从句,表示“一边……一边”、“随着”之意。
goby(时间)过去,流逝;经过,走过(某处)。
Severalyearswentbybeforewemetagain.
过去了好几年我们才再度见面。
Don’tletthisopportunity___________.不要错失良机。
