文档简介

Ⅰ.单项填空
1.(2009年高考福建卷)________ not to miss the flight at 15∶20,the manager set out for the airport in a hurry.
A.Reminding          B.Reminded
C.To remind D.Having reminded
解析:选B。句意:有人提醒经理不要错过15∶20的航班,他匆忙出发去了机场。本题考查非谓语动词作状语。主句主语the manager与remind之间的关系为逻辑上的动宾关系,故排除A、C、D三项,因为这三项表主动,而只有B项表被动。
2.(2010年高考湖南卷)Dina,________ for months to find a job as a waitress,finally took a position at a local advertising agency.
A.struggling B.struggled
C.having struggled D.to struggle
解析:选C。此处分词短语作时间状语,其逻辑主语Dina与struggle为主动关系,故排除B项。由句中的finally可知非谓语动词表示的动作发生在句中谓语took a position之前,故用现在分词的完成主动式。
3.(2009年高考江西卷)________ the right kind of training,these teenage soccer players may one day grow into international stars.
A.Giving B.Having given
C.To give D.Given
解析:选D。考查非谓语动词。如果把句子补充完整应该是:If they are given the right kind of training,可知主语they即these teenage soccer players与give之间是被动关系,所以用过去分词。而A、B、C三项都不表示被动含义。
4.(2009年高考四川卷)________ many times,he finally understood it.
A.Told B.Telling
C.Having told D.Having been told
解析:选D。考查非谓语动词。tell与主语之间的关系是被动关系,故排除表示主动意义的B项和C项。由状语many times可知tell这一动作在谓语动词understand之前发生过多次,所以用having been done来表示被动和完成。
5.(2009年高考天津卷)________ by the advances in technology,many farmers have set up wind farms on their land.
A.Being encouraged B.Encouraging
C.Encouraged D.Having encouraged
解析:选C。考查非谓语动词。由于主语many farmers和作状语的encourage之间是被动关系,排除表示主动意义的B项和D项。而being encouraged除表示被动外,还表示进行。农民们显然不是正在受到科技进步的鼓舞,故排除A项。
6.(2011年汕头高二检测)________ in 1636,Harvard is one of the most famous universities in the United States.
A.Being founded B.It was founded
C.Founded D.Founding
解析:选C。分析句子结构可知应选考查非谓语动词形式作状语的,排除B项,另外found与Harvard之间为被动关系,应用过去分词形式作状语,故选C。
7.(2011年晋中高二检测)________ as the “First Lady of Speech”,Dr Lillian Glass is recognized as one of the world’s leading experts on communication skills.
A.Knowing B.Having known
C.Known D.To be known
解析:选C。 be known as被称为……。Dr Lillian Glass与know之间为被动关系,应用过去分词形式作状语。A、B表主动,应排除;D项表将来,也可排除。
8.________ more attention,the trees could have grown better.
A.Given B.To give
C.Giving D.Having given
解析:选A。考查分词作状语。句子主语the trees与give之间是被动关系,而四个选项中只有A项表示被动意义,故答案选A。Given more attention相当于一个条件状语从句If the trees were given more attention。
9.________ in thought,he almost ran into the car in front of him.
A.Losing B.Having lost
C.Lost D.To lose
解析:选C。考查分词作状语。句意:由于陷入沉思,他差一点撞到前面的车上。be lost in thought为固定搭配,意为“陷入沉思”。过去分词短语lost in thought在句中作原因状语。
10.The research is so designed that once ________ nothing can be done to change it.
A.begins B.having begun
C.beginning D.begun
解析:选D。考查分词作状语。句意:这项调查研究事先计划的如此完好,以至于一旦开始,什么也无法改变它。begin与research之间是被动关系,排除表示主动意义的A、B、C三项。once begun在句中作条件状语,它是状语从句once it is begun的省略形式。
11.Generally speaking,________ according to the directions,the drug has no side effect.
A.when taking B.when taken
C.when to take D.when to be taken
解析:选B。考查分词作状语。完整的说法应是when the drug is taken according to the directions...。由于主句的主语和从句的主语相同,因此可以省略从句的主语the drug和谓语的一部分is,故答案为B。
12.________ into use in April,2000,the hotline was meant for residents reporting water and heating supply breakdowns.
A.Put B.Putting
C.Having put D.Being put
解析:选A。考查过去分词作状语。句子的主语是the hotline与put into use“投入使用”存在被动关系,排除表示主动的B项和C项。D项表示正在投入使用,不符合语境。
13.In order not to be found,I spent the whole night ________ in my room.
A.locking B.locked
C.to lock D.lock
解析:选B。考查过去分词作状语。句意:为了不被找到,我整晚上都把自己锁在自己的房间里。lock的逻辑主语I和lock之间存在被动关系,故用过去分词作伴随状语。本题易受“spend... doing sth.句型的影响,易误选A。其实我并不是把整晚上的时间都用在了“锁”这一动作上,故排除A。
14.________,liquids can be changed into gases.
A.Heating B.To be heated
C.Heated D.Heat
解析:选C。考查过去分词作状语。句意:被加热时,液体可以变成气体。由于对于液体来说是加热的承受者,是被动的,因而选C。A项表示主动,B项表示目的,D项是谓语动词的形式。
15.Unless ________ to speak,you should remain silent at the conference.
A.invited B.inviting
C.being invited D.having invited
解析:选A。考查过去分词作状语。句意:除非受到邀请讲话,否则在大会上你应该保持沉默。invite与you之间是被动关系,排除B、D。being invited表示正在受到邀请,不符合语境。
Ⅱ.句型转换(把下列句子转变成过去分词作状语的结构)

A.high B.surprising

—1978,I suppose.
A.Since B.In
C.From D.After
解析:选A。考查状语从句。句意:——这个国家是什么时候对国际贸易开放的?——我猜是1978年。句子时态是现在完成时,而when指代下文的1978年。故用since when。
8.After he retired from office,Rogers ________painting for a while,but soon lost interest.
A.took up B.saved up

Ⅳ.阅读理解
A group of European researchers from Eindhoven University of Technology(TU/e)are working hard to connect robots with homes.The robots will make sure that homes are nice places to stay and that patients do the right things.
This recently started research project,which has been named KSERA,focuses(关注)on COPD(慢性阻塞性肺病)patients.In 2030 this disease will be the third cause of death worldwide.The disease especially affects the elderly.
In three years’ time several demonstration(示范)houses should be finished,where a robot will play the central role.It follows patients through the house,learns their habits,watches them closely,gives sound advice,turns the air conditioning up or down a bit,and warns a doctor when the patient is not feeling well.Besides,the robot also provides fun in the form of the Internet and videos.“We want to show what is possible in this area,”says project manager Dr.Lydia Meesters.
The TU/e researcher says that this new type of intelligent care house will not be a cold environment.It should be as homely as possible.In an ideal(理想的)situation the only technology you see will be the robot.It will be the contact for all the systems in the homes.
Ethical issues(道德问题)will also be given special focus.The robot must give good advice to patients,but it should not be a policeman,Meesters explains.What to do,for example,when a COPD patient lights a cigarette
The project will cost almost 4 million euros,2.9 million of which will be provided by the EU.Other parties are the Italian research center Institute Superiore Mario Boella,Vienna University of Technology,Hamburg University,the Italian ICT company Consoft,the Central European Institute of Technology in Vienna and the Israeli care provider Maccabi Healthcare Services.

2.Paragraph 3 mainly tells us that robots ________.
A.can do many things
B.are stronger than men
C.are better than doctors
D.can make the best home
解析:选A。段落大意题。文章第三段提到机器人能够做很多事,如:跟随病人、了解他们的习惯、密切注意他们等等。故答案选A。
3.How many parties offered money to KSERA
A.Five. B.Six.
C.Seven. D.Eight.
解析:选C。细节判断题。根据文章最后一段,有多达7个团体对这项研究提供资金援助。故答案选C。
4.According to the passage,the robots will ________.
A.be put into production very soon
B.be popular with the COPD patients
C.make a home feel cold
D.act as a policeman
解析:选B。推理判断题。根据文章第二至四段可知,KSERA这一项目所研究的机器人对患慢性阻塞性肺病的病人是很有帮助的,让他们觉得家不是“冷冰冰”的。但是,这种机器人正处于研究中,并不是很快就能投入生产的。故答案选B。

2.(2011年福州高二检测)“I don’t think it is my ________ that the TV doesn’t work.I just turned it on,that’s all,”said the boy.
A.error B.mistake
C.fault D.duty
解析:选C。考查词义辨析。句意:那个男孩说:“电视机坏了不怪我。我就是打开了它,如此而已。”表示是某人的过错用It is one’s fault。error和mistake意为“错误”但不指某人应该负责。duty“义务;职责”不符合语境。
3.You see the lightning ________it happens,but you hear the thunder later.
A.the instant B.for an instant
C.on the instant D.in an instant
解析:选A。you see the lightning和it happens是两个完整的句子,因此需要一个连词将它们连接,B、C、D选项都是副词短语。the instant可用作连词。
4.Many of the party’s traditional voters ________it at the last election.
A.reserved B.deserted
C.preserved D.depressed

A.Praising;excited B.To praise;exciting
C.Praised;exciting D.Praised;excited
解析:选D。考查非谓语动词。句意:由于工作出色而受到热情赞扬,他激动地难以入睡。praise与he之间是被动关系,排除A、B。exciting“令人兴奋的”不符合语境。故选D。
7.________around the Water Cube, we were then taken to see the Bird’s Nest for the 2008 Olympic Games.
A.Having shown B.To be shown
C.Having been shown D.To show
解析:选C。考查分词作状语。由于we和show之间是被动关系,排除A项和D项。B项作状语表示目的,不符合语境。这里 show与take之间有明显的时间先后顺序,故用having been done表示完成被动。
8.I thought her nice and honest ________I met her.
A.first time B.for the first time
C.the first time D.by the first time
解析:选C。考查the first time接状语从句的用法。句意:我第一次遇到她就认为她善良诚实。表示“第一次……时”一定要用定冠词the,排除A。for the first time是介词短语,在句子中作状语。by the first time搭配错误。

A.sweep up B.speed up
C.make up D.save up
解析:选B。句意:我们希望当地政府采取的这些措施能加速事情的进展。speed up“加速;使加速”,符合题意。sweep up“横扫”;make up“组成;构成;虚构”;save up“节省”。

12.A.But B.So
C.Then D.Though
解析:选A。stronger与前面的weaker构成转折关系,故用but。
13.A.in other words B.all in all
C.as a result D.in addition
解析:选C。我们很少用胳膊和腿,因此就越来越弱了。less use与weaker构成因果关系,故用as a result“因此”。in other words“换句话说”;all in all“总之;总而言之”;in addition“此外;再者”。
14.A.effective B.optimistic
C.painful D.sensitive
解析:选D。根据下文的a great deal可知我们的手指将会变得越来越灵敏(sensitive)。effective“有效的”;optimistic“乐观的”;painful“疼痛的”。
15.A.disappear B.move
C.remove D.rise
解析:选A。根据下句可知头发不再有用,所以最终会消失。
16.A.expression B.impression
C.influence D.connection
解析:选B。impression“印象”,指给我们留下了一个未来人不好看的印象。expression“表情;描述”;influence“影响”;connection“联系”。
17.A.false B.perfect
C.exact D.true
解析:选D。指人类不如以前漂亮这件事是真的。
18.A.changes B.motivations
C.approaches D.adjustments
解析:选A。上文提到人在身高、大脑、眼睛、胳膊、手以及头发等方面都发生了变化,故用changes。
19.A.He B.They
C.We D.It
解析:选A。此句中用he代替future man(未来的人类)。由不定冠词a可知不能选B。
20.A.cautious B.rough
C.previous D.similar
解析:选D。be similar to“与……相似”,指未来的人和我们在感情和思想上还是相似的。
Ⅴ.阅读理解
Ever dreamed of having a robot servant who would do all the boring housework around the house?Well mechanized domestic staff have come one step closer,thanks to an android(机器人)being developed in Japan.
Researchers at Tokyo University’s JSK Robotics Laboratory have created a humanoid called Kojiro,who is learning how to copy how we walk.
What makes him unique is that he has a skeletal(骨骼的)structure similar to that of humans,which means he moves in a more natural fashion,and bends and twists by his artificial spine(脊柱).
The team,led by Professor Nakanishi,said this newly developed spine would allow them to manufacture lighter and more flexible robots in the future to serve in the home.
In one scientific paper,they wrote:“Now normal humanoid robots are not suitable for working in our daily environment.”Lack of safety and versatility(多用途)is the main reason;their hard and heavy bodies can hurt humans or surrounding objects,and they can do limited tasks compared with what humans do in daily life.
Traditional robots have limbs and torsos(躯干)powered by heavy motors at the joints.However in Kojiro,the motors are lightweight and used to pull cables attached to different locations on the body.This copies how our own muscles and tendons(腱)contract and relax when we move.
The skillful system of around 100 such tendon muscle structures work together to give Kojiro 60 degrees of freedom.The humanoid is also made mostly from light and flexible materials,which would make him less of a danger around the home.
The researchers found the most difficult challenge was finding a way to make such a skillful robot walk.“The system has strong nonlinearity(非连续性)and is hard to model precisely.To control such a system,a kind of learning method is needed,”the team wrote.
At present the scientists are testing Kojiro’s smaller movements using a games console controller.The team plan to slightly improve the computer algorithms(算法)that control the robot’s movements as they go and hope it will one day be able to handle complex movements using all of its limbs.Then perhaps one day,you will find Kojiro serving you breakfast in bed.
