1、单元综合测评(三)Unit 3Tomorrows world(时间：100分钟；满分：120分)【XZB2017TBYLYYB04012】.阅读理解(共15小题；每小题2分，满分30分)AIt is now February 7，2035. The search engine TalkTalk will open to the public next week and this service will be something beyond your imagination. For the first time you can not only talk to the search eng
2、ine，but you can discuss with it what you are looking for.For example, if you want to know more about the oil price，TalkTalk asks if you want to know the current oil price，the development of the oil price，or news related to the oil price.You say that you want to read news about it and TalkTalk asks y
3、ou if you prefer a certain source.TalkTalk then directs you to your source，or lets you have the latest news related to the oil price in order from the most respected sources.Compared with other search services that use a certain algorithm(程序) to provide data from a search，the artificial intelligence
4、(人工智能) behind TalkTalk is said to easily spot if a certain source is aiming to cheat the searcher. TalkTalk also judges and stores every given reply and discussion，to learn how to give correct answers.TalkTalk is also set to answer questions directly where there is a definite answer.How well this wi
5、ll work in the long run is yet to be seen，but thousands of people have tested TalkTalk and the quality is really good.The first talking search engine saw the light of day more than 30 years ago and was called Speegle.It could read you the results from a written search on the Internet，and was mostly
6、for blind people.So far，TalkTalk can not read the information from a certain source to you by phone，if it is not freely available.There are currently talks to find an arrangement for this，but it would most likely be difficult because of copyright (版权)TalkTalk is available over the Internet and also
7、by phone, even though it only speaks English.There are no plans to add other languages in the near future，most likely because it will cost a lot of money.When you are tired of asking TalkTalk all your questions，just ask，“Where is TalkTalk？” and you will get an answer that will make you leave it with
8、 a smile on your lips.1The example in Paragraph 2 is given to show _Ahow to use the search engine TalkTalkBhow to search for news on the InternetCthat the oil price is a very hot issue currentlyDthat TalkTalk has a very high intelligence2What can be inferred from the text?ATalkTalk can read all the

10、ad the text?AOpinion.BCulture.CLifestyles. DTechnology.BNot long ago，an airplane was flying over New Zealand. There was a television camera crew on board.Suddenly，out in the night sky，a bright sphere(球体)came into view.Everyone on board saw it and everyone thought，“UFO”Unidentified Flying Object. The
11、 camera crew went into action and started filming.That week people all over the world saw the film of the mysterious light on their television screens.What was it? Was it a spaceship full of visitors from another planet? The captain of the airplane and the film crew believed it was.Other observers h
12、ad many different explanations.Some said it was Venus (金星)Others said it was just a trick(幻影)of light.An air traffic controller also saw it on his radar screen.He thought that a flock(一群) of birds was causing dots on his radar screen when the “UFO” appeared.Most astronomers now believe that what the
13、se people saw was almost certainly the planet Venus. At that time of year it was very bright and easy to see.And from a moving airplane it can appear to be moving fast.So far there is no proof that UFOs or spaceships from other planets do exist.These years investigators of UFOs have investigated tho
14、usands of sightings or occasions when people said they saw a UFO.Ninety percent of these turned out to have a simple explanation.However，it is a good idea to keep an open mind. Scientists in some countries are trying to persuade their governments to help them study UFOs.And they are planning to coop
15、erate internationally on reporting and investigating sightings of UFOs.After all，it is quite possible that there is life out there in the universe.And if something is alive，it is quite possible that it will come to visit us.5From the first paragraph，we can know that _Aa television camera crew and so

17、f lightDdots caused by a flock of birds7Why do most astronomers now believe that what these people saw was almost certainly the planet Venus?ABecause they think at the time when it was seen，Venus should be very bright and easy to see.BBecause they saw it with their own eyes.CBecause they have proved
18、 UFOs or spaceships from Venus do exist.DBecause it was moving very fast when they saw it.8What is the main idea of the passage?AThe UFOan Unidentified Flying Object was filmed by a television crew.BThe discussion about what on earth the UFO is.CScientists studying the UFO are trying to ask the gove
19、rnments to offer them help.DLife in the universe will come to visit our earth.CScientists have found an unusual way to prevent our planet from overheating：move it to a cooler spot.All you have to do is send a few comets(彗星) in the direction of Earth，and its orbit will be changed.Our world will then
20、be sent into a safer，colder part of the solar system.This idea for improving our climate comes from a group of US National Aeronautics and Space Administration (NASA) engineers and American astronomers.They say their plan could add another six billion years to the useful lifetime of our planeteffect
21、ively doubling its working life.The plan put forward by Dr.Laughlin，and his colleagues Don Korycansky and Fred Adams，needs carefully directing a comet of asteroid (小行星) so that it passes close by our planet and sends some of its gravitational energy to Earth.“Earths orbital speed would increase as a
22、 result and we would move to a higher orbit away from the Sun，” Laughlin said.Engineers would then direct their comet so that it passed close to Jupiter or Saturn.The comet would pick up energy from one of the giant planets.Later its orbit would bring it back to Earth，and the process would be repeat
23、ed.In the short term，the plan provides an ideal way to global warming，although the team was actually concerned with a much greater danger.The sun is certain to heat up in about a billion years and so “seriously compromise” our biosphere(生物圈)by cooking us.Thats why the group decided to try to save Ea
24、rth.The plan has one or two worrying aspects，however.For a start，space engineers would have to be very careful about how they directed their asteroid or comet towards Earth.The smallest miscalculation(误算) in orbit could fire it straight at Earthwith deadly results.There is also the question of the M
25、oon.As the scientific American magazine points out，if Earth was pushed out of its current position it is “most likely that the Moon would be stripped away from Earth，” it states.This would change our planets climate.9If the plan is successful，Earth will have a working life of _ years.A12 billion B6
26、billionC18 billion D24 billion10What makes the scientists plan to save Earth?AA few comets are moving to the direction of Earth.BEarths working life is coming to an end soon.CEarth will become too hot for mankind to keep alive.DThe moon is moving farther and farther away from Earth.11What does the u
27、nderlined word“compromise”in Paragraph 6 mean?AProvide. BBenefit.CShare. DEndanger.12Which of the following best shows how the plan would work?DWhat will man be like in the futurein 5，000 or even 50，000 years from now? We can only make guesses，of course，but we can be sure that he will be different f
28、rom what he is today，for man is slowly changing all the time.Let us take an obvious example.Man，even five hundred years ago，was shorter than he is today.Now，on average，men are about three inches taller.Five hundred years is a relatively short period of time，so we may assume that man will continue to
29、 grow taller.Again，in the modern world we use our brains a great deal.Even so，we still make use of only about 20% of the brains capacity.As time goes on，however，we shall have to use our brains more and more，and eventually we shall need larger ones! This is likely to bring about a physical change too
30、: the head，in particular the forehead，will grow larger.Nowadays our eyes are in constant use.In fact，we use them so much that very often they become weaker and we have to wear glasses.But over a very long period of time it is likely that mans eyes will grow stronger.On the other hand，we tend to make
31、 less use of our arms and legs.These，as a result，are likely to grow weaker.At the same time，however，our fingers will grow more sensitive because they are used a great deal in modern life.But what about hair? This will probably disappear from the body altogether in course of time because it does not
32、serve a useful purpose any longer.In the future，then，both sexes are likely to be bald.Perhaps all this gives the impression that future man will not be a very attractive creature to look at! This may well be true.All the same，in spite of all these changes，future man will still have a lot in common w
33、ith us.He will still be a human being，with thoughts and emotions similar to our own.13The passage mainly tells us that _Amans life will be different in the futureBfuture man will look quite different from usCman is growing taller and uglier as time passesDhumans organs functions will become weak14Wh
34、at will be true about a human being in the future?AHe will be hairless because hair is no longer useful.BHe will have smaller eyes and will wear better glasses.CHis fingers will grow weaker because he wont have to make use of them.DHe will think and feel in a different way.15It is implied that _Ahum
35、an beings will become more attractive in the futureBless use of a bodily organ may lead to its degeneration(退化)Chuman beings hope for a change in the future lifeDfuture life is always predictable.阅读填句(共5小题；每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。Any car accident is frightening，but an ac

37、can save yourself from a sinking vehicle.Brace yourself for impact (撞击力)As soon as youre aware that youre going off the road and into a body of water，adopt a brace position.The impact could set off the airbag system in your vehicle，so you should place both hands on the steering wheel(方向盘) in the “te
