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

8、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

9、 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 teles

10、cope. - 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 light years away from Earth. One light year is about 6 trillion(万亿 )miles. Even th

11、e 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 remain one of the mysteries of the universe. 16 Black holes are part of

12、 space. （ A） Right （ B） Wrong （ C） Not mentioned 17 Black holes exist but are difficult to observe. （ A） Right （ B） Wrong （ C） Not mentioned 18 The center of a black hole is empty. （ A） Right （ B） Wrong （ C） Not mentioned 19 The attraction of two large stars leads to gravity. （ A） Right （ B） Wrong （

This is wh

15、at many scientists are doing as they work on the Human Genome Project. The aim of the project is to decode(破译 )all of the some 100, 000 genes in the human body. Scientists are using DNA fingerprinting techniques to do the decoding. 2 DNA is the substance found in the chromosomes(染色体 )of a cell. A ch

16、romosome is a chain of genes. Each gene carries a piece of genetic information. At any one moment in a cell, thousands of genes are turned on and off to produce proteins(蛋白质 ). The challenge for scientists is to find out what role each gene plays in protein production. At some point this decoding wi

17、ll be complete. Then scientists will have a map of an ideal genome, or a picture of the total genetic nature of a human being. The ideal genome is called a consensus(交感 )genome. Everything works well in a consensus genome. 3 But no one in the world has a consensus genome. Everyones genome is differe

18、nt from the ideal. These differences are referred to as genetic mutations(突变 ). Genetic mutations in a persons genome mean that the person has a greater than average chance of suffering from health problems. Some problems are not life-threatening. These would include things like colorblindness, or m

19、ild headaches. Other problems are serious, such as heart disease, or cancer. 4 It will take years to identify the role of each of the 100, 000 genes, The short-term goal of the project is to find the physical and mental health problems a person is likely to encounter during his or her lifetime. The

20、long-term goal is to have each person live a longer, healthier life. 23 A. How does DNA work? B. What is the Human Genome Project about? C. How are the DNA samples collected? D. What are the goals of the Human Genome Project? E. What is the role of each gene? F. What are the consequences of genetic

23、ther 50 million injuries. To reduce car crash rate, much research now is focused on safety and new fuels-though some electric vehicle and biofuel research aims at going faster. Travelling at speed has always been dangerous. One advanced area of research in motoring safety is the use of digital in-ca

24、r assistants. They can ensure you dont miss important road signs or fall asleep. Most crashes result from human and not mechanical faults. Some safety developments aim to improve your vision. Radar can spot obstacles in fog, while other technology “sees through“ big vehicles blocking your view. And

25、improvements to seat belts, pedal(脚踏 )controls and tyres are making driving smoother and safer. The colour of a car has been found to be linked with safety, as have, less surprisingly, size and shape. But whatever is in the fuel tank, you dont want a thief in the driving seat and there have been man

26、y innovations(创新 ). Satellite tracking and remote communications can also come into play if you crash, automatically calling for help. Accidents cause many traffic jams, but there are more subtle interplays between vehicles that can cause jams even on a clear but busy road. Such jams can be analyzed

27、 using statistical tools. Robotic drivers could be programmed to make traffic flow smoothly and will perhaps one day be everyones personal chauffeur(司机 ), but their latest efforts suggest that wont be soon. 31 To reduce car crash rate, many scientists are working hard to （ A） design fully automatic

33、 ), if it is a large dinner napkin. If you need to leave the table during the meal, place your napkin on your chair as a signal to your server that you will be returning. Once the meal is over, place your napkin neatly on the table to the right of your dinner plate. Do not refold it. Use a napkin on

34、ly for your mouth. Never use it for your nose, face or forehead. Use of utensils(餐具 ) Start with the knife, fork or spoon furthest from your plate, and work your way in, using one utensil for each course. If soup is served, remember to spoon away from yourself. This helps stop the drips. Do not put

35、the entire soup spoon in your mouth. Instead, fill a soup spoon about 75 per cent with soup, and sip(啜饮 )it from the side noiselessly.

Coal is still used, mostly in power stations, to cover one-quarter of our energy needs, but

41、 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. L

42、ess-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 electr

43、icity. 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 station to use tidal

44、(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 of turbines t

45、hat 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 totally

46、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 unrelia
