7、r 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
8、 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 tele
9、scope. 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 the most pow
10、erful 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 space.A.RightB

14、00 genes in the human body.Scientists are using DNA fingerprinting techniques to do the decoding.2DNA is the substance found in the chromosomes（染色体）of a cell.A chromosome 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
15、 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 will 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
16、called a consensus（交感）genome.Everything works well in a consensus genome.3But no one in the world has a consensus genome.Everyones genome is different 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 th

39、er.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.Renewablerefers to the fact that these resources are not used faster than they can be replaced.Hydroelectric（水力发电的）power is now
40、the most common form of renewable energy,supplying around 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 elec
41、tricity demand.In 2003,the first commercial power station 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
42、 between 1999 and 2005.Modern wind farms consist of 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 ofte
