[单项选择]第二篇Hurricane(飓风)Katrina
A hurricane is a fiercely powerful,rotating(旋转的)form of tropical storm that can be 124 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 release 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 November 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 col
A. lower part.
B. rotating part.
C. calm central part.
D. most violent part.

[单项选择]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 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 contemporary couples benefit in different ways from relationships.Women no longer rely upon partners for economic security or status.A man doesn’t 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 partnership 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) b

[单项选择]Walk a Quarter-Mile or Die
If you can walk a quarter-mile,odds(可能性)are you have at least six years of life left in you,scientists say.And the faster you can(51)it,the longer you might live.
While walking is no guarantee of(52)or longevity(长寿),a new study found that the ability of elderly people to do the quarter-mile was an“important determinant(决定因素)”in whether or not they’d be(53)six years later and how much illness and disability they would endure.
“The(54)to complete this walk was a powerful predictor of health outcomes,”said study leader Anne Newman of the University of Pittsburgh School of Medicine.“In fact,we(55)that the people who could not complete the walk were(56)an extremely high risk of later disability and death.”
Newman and colleagues recruited nearly 2,700 white and African-American men and women aged 70 to 79 to(57)the walk.All the participants were screened and determined to be in relatively(58)health,and they had all said they had previously walked th

[单项选择] Black Holes
Most scientists agree that black holes exist but are nearly impossible to locate.A black hole in the universe is not a solid object,like a 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 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 light 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

The whole of the United States cheered its latest hero,Ashley Smith,with the Federal Bureau of lnvestigation saying it was planning to give a big reward to her for having a brave heart and wise mind.
(46)She was moving into her apartment in Atlanta,Georgia early on the morning of March 12,when a man followed her to her door and put a gun to her side.“I started walking to my door,and I felt really,really afraid,”she said in a TV interview last week.The man was Brian Nichols,33.He was suspected of killing three people at an Atlanta courthouse(法院)on March 11 and later of killing a federal agent.(47)
Nichols tied Smith up with tape,but released her after she repeatedly begged him not to take her life.“I told him if he hurt me,my little girl wouldn’t have a mummy,”she said.In order to calm the man down,she read to him from“The Purpose-Driven Life”,a best-selling religious book.He asked her to repeat a paragraph“about what you thought your purpose in life was-what

[单项选择] 第一篇Renewable Energy Sources
Today petroleum(石油)provides around 40% of the world’s energy needs,mostly fuelling automobiles.Coal is still used,mostly in power stations,to cover 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 accessible 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 around 20% of world electricity.China’s Three Gorges Dam is the largest ever.At five times the size of the US’s Hoover Dam,its 26 turbines(涡轮机)will generate the equivalent energy of 18 coal-fired power stations.It wi

[单项选择]Memory Test
1“I am going to give you five techniques that will enable you to remember anything you need to know at school,”promised lecturer lan Robinson to a hundred schoolchildren.He slapped his hand down on the table.“When I’ve 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 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 was already lecturing to schools on his magic techniques when it struck him that students might find memory techniques even more valuable.“It wasn’t difficult area to move inot,as the stuff’s all there in books.”So he summarized everything t
