paying attention to the revolution that is taking place in bio-technology (生物技术). With the help of new
medicine, the human body will last a very long time. Death will come mainly from accidents, murder and
war. Today"s leading killers, such as heart disease, cancer, and aging itself, will become distant memories.
In discussion of technological changes, the Internet gets most of the attention these days. But the change
in medicine can be the real technological event of our times. How long can humans live? Human brains were
known to decide the final death. Cells are the basic units of all living things, and until recently, scientists were
sure that the life of cells could not go much beyond l20 years because the basic materials of cells, such as
those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime
between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will
be able to take medicine to repair their organs. The medicine, made up of the basic building materials of life,
will build new brain cells, heart cells, and so on-in much the same way our bodies make new skin cells to take
the place of old ones.
It is exciting to imaging that the advance in technology may be changing the most basic condition of human
existence, but many technical problems still must be cleared up on the way to this wonderful future.
B. accidents and war
C. accidents and aging
D. heart disease and war

| To wash yourself, you take a bath (洗澡) or a shower. Animals need to keep clean, too. How do animals clean themselves? Cats lick (舔) themselves to keep their fur clean. Have you ever watched a pet cat clean itself? Elephants take baths much as you do. But instead of jumping into the tub (浴缸), they walk into a river or lake. Pigs also like to roll around in water. This keeps them clean and cool. If there is no clean water, they will roll in mud (泥) on a hot day. They do this to cool off. Pigs do not really like mud. They are happier in a nice, clean pond (水池). Bats have a funny way to keep clean. They lick their thumbs to clean their ears! Guess how polar bears clean themselves. They use snow, of course! Some animals take baths in dust instead of water! The wombat (毛鼻袋熊) is an Australian animal with lots of fur. To get clean, it lies down. Then it covers itself with sand! Birds clean themselves in many ways. Sometimes they wash in water. That"s why some people put birdbaths in their yard. At other times birds take dust baths, just like wombats. Birds also use their beaks (喙) to keep their feathers clean. They use their beaks the way you use a comb. Sometimes a bird has itchy bugs (发痒的虫子) in its feathers. Birds may use ants to help them clean off the bugs. A bird will lie down on an ant nest. Then the ants will crawl on the bird. The ants make a kind of bug spray (喷雾) on the feathers;. Then the itchy bugs die! Birds take baths in something else besides dust and ants! Some birds take "smoke baths" They sit on chimneys. They wave their wings in the smoke! | |

| Honeybees are disappearing for unknown reasons around the United States. Last winter, bees disappeared from 23 percent of American beekeeping businesses. Causes of the occurrence, however, have remained a puzzle. Now, scientists from several universities and the United States Department of Agriculture say they have a possible explanation for the bee decline (数量下降). It is a little known virus called Israeli acute-paralysis virus (IAPV).The virus kills bees. Researchers in Israel first described it in 2004, but until now, bee experts haven"t paid much attention to it. When trying to find out why the bees were disappearing, a research team at Columbia University studied bee communities, some with and others without decline. The research turned up large numbers of two types of fungi (真菌) once believed of causing the bee decline. The research results, however, showed that the fungi were almost as common in communities without a decline as they were in communities with a decline. The research concluded that the two fungi probably weren"t the cause. Studies of the presence of IAPV, however, showed more interesting information. In those studies, done by a team at Pennsylvania State University in University Park, the virus showed up in 83 percent of samples from communities with symptoms. Only five percent of samples from symptomless communities had it. Scientists still don"t know whether IAPV can single-handedly cause the bee decline. They believe that even if the virus is making communities sick, it could have a partner in crime. It"s possible, for instance, that insects or chemicals in the environment weaken bees, making them more likely to catch IAPV. Scientists are still trying to figure out how IAPV came to the United States. The United States now allows bee products to be imported from Canada, Australia, and New Zealand. If it turns out that this trade is spreading disease, the rules might eventually change. | |

| [ ] | |
| A. the virus is not only among insects B. the virus could also cause other damages C. the virus is not the only cause for the bee decline D. the virus may be caused by the polluted environment | |
| 4. What is the best title for the passage? | |
| [ ] | |

| While all my classmates seem to be crazy about a one-way ticket to Mars (火星), I"d rather say Mars is totally unsuitable for human existence. People won"t have enough food supplies there, and the terrible environment would make it impossible for them to live a long life. Besides, the journey won"t be safe. Can anybody explain to me just why people would go to Mars, never to return? Steve Minear, UK Here are the things you can think of: the desire to explore a foreign and unique environment, the excitement of being the first humans to open up a new world, the expectation of fame and glory…For scientists there is another reason. Their observations and research will probably lead to great scientific achievements. Donal Trollop, Canada There are already too many people on the Earth. I think that sometime before the end of the century, there will be a human colony (殖民地) on Mars. It will happen when people finally realize that two-way trips to the red planet Mars are unnecessary. Most of the danger of space Flight is in the launches (发射) and landings. Cutting the trip home would therefore reduce the danger of accidents, save a lot of money, and open the way to building an everlasting human settlement on another world. Enough supplies can be sent on ahead. And every two years more supplies and more people will be needed, and Mars is far more pleasant than the other planets in the outer space. Paul Davies. USA | |
| 1. The main purpose of Steve Minear"s writing is _____. | |
| [ ] | |
| A. to report his classmates" discussion B. to invite an answer to his question C. to explain the natural state of Mars D. to show his agreement on going to Mars | |
| 2. Which of the following best states Donal Trollop"s idea? | |
| [ ] | |
| A. There is a plan to send humans to Mars. B. There are many reasons for going to Mars. C. Scientists become famous by doing research on Mars. D. It is possible to build an Earth-like environment on Mars. | |
| 3. Paul Davies points out that _____. | |
| [ ] | |
| A. humans need only a one-way ticket to Mars B. two-way trips to Mars will be made safe soon C. it is easy to reduce the danger and cost of flights to Mars D. it is cheap to build an everlasting human settlement on Mars | |
| 4. What does Paul Davies think of human existence on Mars? | |
| [ ] | |
| A. Humans will have to bring all they need from the Earth. B. Humans will find Mars totally unsuitable for living. C. Humans can produce everything they need. D. Humans can live longer in the colony on Mars. |
