7、 planet,but it is shaped like a sphere (球体).Astronomers(天文学家)think that at the center of a black hole there is a single point in space with infinite(无限的)density(稠密).This single point is called a singularity (奇点).If the singularity theory is correct,it means that when a massive star collapses,all the

8、 material in it disappears into the singularity.The center of a black hole would not really be a hole at all,but an infinitely dense point.Anything that crosses the black hole is pulled in by its great gravity. Although black holes do exist,they are difficult to observe.These are the reasons. No lig

9、ht or anything else comes out of black holes.As a result,they are invisible to a telescope. In astronomical terms,black holes are truly.For example,a black hole formed by the collapse of a giant star would have an event horizon(视界)only 18 miles across. The nearest black holes would be dozens of ligh

10、t years away from Earth.One light year is about 6 trillion(万亿)miles.Even the most powerful telescopes could not pick out an object so small at such a great distance. In 1994 the Hubble Space Telescope provided evidence that black holes exist.There are still answers to be found,however,so black holes

11、 remain one of the mysteries of the universe. （分数：7.00）(1).Black holes are part of space. （分数：1.00）A.RightB.WrongC.Not mentioned(2).Black holes exist but are difficult to observe. （分数：1.00）A.RightB.WrongC.Not mentioned(3).The center of a black hole is empty. （分数：1.00）A.RightB.WrongC.Not mentioned(4)

14、obinson to a hundred schoolchildren.He slapped his hand down on the table.“When Ive finished in two hours time,your work will be far more effective and productive.Anyone not interested,leave now.”The entire room sat still. 2Robinson calls himself the Mind Magician (魔术师).He specializes in doing magic

15、 tricks that look totally impossible,and then he reveals that they involve nothing more mysterious than good old-fashioned trickery (骗术).“I have always been interested in tricks involving memory-being able to reel off (一口气 说出) the order of cards in a pack,that sort of thing,”he explains. 3Robinson w

16、as already lecturing to schools on his magic techniques when it struck him that students might find memory techniques even more valuable.“It wasnt difficult area to move inot,as the stuffs all there in books.”So he summarized everything to make a two-hour lecture about five techniques. 4“You want to

17、 learn a list of a hundred things?A thousand?No problem,”says Robinson.The scandal is that every child is not taught the techniques from the beginning of their school life.The schoolchildren who were watching him thought it was brilliant.“I wish Id been told this earlier,”commented Mark,after Robins

18、on had shown them how to construct“mental journeys”. 5Essentially,you visualize (想象) a walk down a street,or a trip round a room,and pick the points where you will put the things you want to remember-the lamppost,the fruit bowl.Then in each location you put a visual representation of your list-phras

19、al verbs,historical dates,whatever-making them as strange as possible.It is that simple,and it works. 6The reaction of schools has been uniformly enthusiastic.“The pupils benefited enormously from lans presentation,”says Dr Johnston,head of the school where Robinson was speaking.“ldeally we should r

23、one-quarter of our energy needs,but it is the least efficient,unhealthiest and most environmentally damaging fossil fuel(矿物燃料).Natural gas reserves could fill some of the gap from oil,but reserves of that will not last into the 22nd century either.Most experts predict we will exhaust easily accessib

24、le reserves within 50 years.Less-polluting renewable energy sources offer a more practical long-term energy solution.“Renewable”refers to the fact that these resources are not used faster than they can be replaced. Hydroelectric(水力发电的)power is now the most common form of renewable energy,supplying a

25、round 20% of world electricity.Chinas Three Gorges Dam is the largest ever.At five times the size of the USs Hoover Dam,its 26 turbines(涡轮机)will generate the equivalent energy of 18 coal-fired power stations.It will satisfy 3% of Chinas entire electricity demand. In 2003,the first commercial power s

26、tation to use tidal(潮汐的)currents in the open sea opened in Norway.It is designed like windmill(风车),but others take the form of turbines. As prices fall,wind power has become the fastest growing type of electricity generation-quadrupling(翻两番)worldwide between 1999 and 2005.Modern wind farms consist o

27、f turbines that generate electricity.Though it will be more expensive,there is more than enough wind to provide the worlds entire energy needs.Wind farms come in onshore and offshore forms.They can often end up at spots of natural beauty,and are often unpopular with residents.And turbines are not to

28、tally harmless-they can interfere with radar,alter climate and kill sea birds.Scotland is building Europes largest wind farm,which will power 200,000 homes.The UKs goal is to generate one-fifth of power from renewable sources,mainly wind,by 2020.But this may cause problems,because wind is unreliable

29、. （分数：15.00）(1).According to the passage,which of the following is the most polluting energy resource? （分数：3.00）A.PetroleumB.CoalC.Natural gasD.Water(2).Chinas Three Gorges Dam （分数：3.00）A.is the first hydroelectric dam in the world.B.is of the same size as the USs Hoover Dam.C.can generate around 3%

30、 of world electricity.D.is the largest hydroelectric dam in the world.(3).Which country took the lead in making use of tidal currents to produce power in 2003? （分数：3.00）A.The UKB.China.C.NorwayD.The US.(4).One of the problems with wind farms is that （分数：3.00）A.there is not enough wind.B.wind is not

31、reliable.C.they can only be built on the sea.D.they might influence the world economy.(5).According to the passage,resources like wind are （分数：3.00）A.renewableB.recyclableC.damagingD.scarce.第二篇 Hurricane(飓风)Katrina A hurricane is a fiercely powerful,rotating(旋转的)form of tropical storm that can be 12

32、4 to 1,240 miles in diameter.The term hurricane is derived from Hurican,the name of a native American storm god.Hurricanes are typical of a calm central region of low pressure between 12 to 60 miles in diameter,known as the eye.They occur in tropical regions.Over its lifetime,one of these can releas

33、e as much energy as 10,000 nuclear bombs. The seed for hurricane formation is a cluster(聚集)of thunderstoms over warm tropical waters.Hurricanes can only form and be fed when the sea-surface temperature exceeds 27 and the surrounding atmosphere is calm.These requirements are met between June and Nove

34、mber in the northern part of the world. Under these conditions,large quantities of water evaporate(蒸发)and condense(冷凝)into clouds and rain-releasing heat in the process.It is this heat energy,combined with the rotation of the Earth,that drives a hurricane. When the warm column of air from the sea su

35、rface first begins to rise,it causes an area of low pressure.This in turn creates wind as air is drawn into the area.This spinning wind drags up more moist air from the sea surface in a process that strengthens the storm.Cold air falls back to the ocean surface through the eye and on the outside of

36、the storm. Initially,when wind speeds reach 23 miles per hour,these mild,wet and grey weather systems are known as depressions,or low air pressure.Hurricane Katrina formed in this way over the south-eastern Bahamas on 23 August 2005.Katrina has had a devastating impact on the Gulf Coast of the US,le

37、aving a disaster zone of 90,000 square miles in its wake(尾迹)-almost the size of the UK.Thousands have been killed or injured and more than half a million people have become homeless in a humanitarian(人道主义的)crisis of a scale not seen in the US since the Great Depression.The cost of the damage may top

38、 $100 billion. （分数：15.00）(1).The eye of a hurricane refers to its （分数：3.00）A.lower part.B.rotating part.C.calm central part.D.most violent part.(2).Which of the following is NOT a “requirement”for the formation of a hurricane? （分数：3.00）A.Calm surrounding atmosphere.B.High air pressure.C.Warm sea-sur

39、face temperature.D.A group of thunderstorms over warm tropical waters.(3).When the warm air from the sea surface begins to rise,it （分数：3.00）A.creates an area of low pressure.B.supplies cold air to the eye of a hurricane.C.increases the sea-surface temperature.D.strengthens the rotation of the earth.

40、(4).The word“impact”(paragragh 5)could be best replaced by （分数：3.00）A.“function”.B.“pressure”.C.“disaster”.D.“effect”.(5).Which of the following is NOT true of Hurricane Katrina according to the last paragraph? （分数：3.00）A.The area affected is almost as big as the UK.B.It has left a disaster zone of

41、90,000 square miles.C.Over half a million people have been forced to leave their homes.D.This crisis is more serious than that of the Great Depression.第三篇 Trying to Find a Parther One of the most striking findings of a recent poll in the UK is that of the people inbterviewed,one in two believes that

42、 it is becoming more difficult to meet someone to start a family with. Why are many finding it increasingly difficult to start and sustain intimate relationships?Does modern life really make it harder to fall in love?Or are we making it harder for ourselves? It is certainly the case today that conte

43、mporary couples benefit in different ways from relationships.Women no longer rely upon partners for economic security or status.A man doesnt expect his spouse to be in sole charge of running his household and raising his children. But perhaps the knowledge that we can live perfectly well without a p

44、artnership means that it takes much more to persuade people to abandon their independence. In theory,finding a partner should be much simpler these days.Only a few generations ago,your choice of soulmate (心上人) was constrained(限制) by geography,social convention and family tradition.Although it was ne

45、ver explicit,many marriages were essentially arranged. Now those barriers have been broken down.You can approach a builder or a brain surgeon in any bar in any city on any given evening.When the world is your oyster (牡蛎),you surely have a better chance of finding a pearl. But it seems that the old c

46、onventions have been replaced by an even tighter constraint:the tyranny of choice. The expectations of partners are inflated(提高) to an unmanageable degree:good looks,impressive salary,kind to grandmother,and right socks.There is no room for error in the first impression. We think that a relationship

47、 can be perfect.If it isnt,it is disposable.We work to protect ourselves against future heartache and dont put in the hard emotional labor needed to build a strong relationship.Of course,this is complicated by realities.The cost of housing and child-rearing creates pressure to have a stable income a

48、nd career before a life partnership. （分数：15.00）(1).What does the recent poll show? （分数：3.00）A.It is getting more difficult for a woman to find her husband.B.It is getting increasingly difficult to start a familyl.C.It is getting more difficult for a man to find his wife.D.It is getting increasingly

49、difficult to develop an intimate relationship with your spouse.(2).Which of the following is NOT true about a contemporary married couple? （分数：3.00）A.The wife doesnt have to raise the children all by herself.B.The husband doesnt have to support the family all by himself.C.The wife is, no l, onger the only person to manage the household.D.They will receive a large sum of money from the govemment.(3).Which of the following was NOT a constraint on ones choice of soulmate in
