9、ging Human Life/B Prolonging human life has increased the size of the human population. Many people alive today would have died of childhood diseases if they had been born 100 years ago. Because more people live longer, there are more people around at any given time. In fact, it is a decrease in dea

10、th rates, not an increase in birthrates, that has led to the population explosion. Prolonging human life has also increased the dependency load. In all societies, people who are disabled or too young or too old to work are dependent on the rest of society to provide for them. In hunting and gatherin

11、g cultures, old people who could not keep up might be left behind to die. In times of famine, infants might be allowed to die because they could not survive if their parents starved, whereas if the parents survived they could have another child. In most contemporary societies, people feel a moral ob

12、ligation to keep people alive whether they can work or not. We have a great many people today who live past the age at which they want to work or are able to work; we also have roles which require people to retire at a certain age. Unless these people were able to save money for their retirement, so

13、mebody else must support them. In the United States many retired people live on social security checks which are so little that they must live in near poverty. Older people have more illness than young or middle-aged people; unless they have wealth or private or government insurance, they must often

14、 go on welfare” if they have a serious illness. When older people become senile or too weak and ill to care for themselves, they create grave problems for their families. In the past and in some traditional cultures, they would be cared for at home until they died. Today, with must members of a hous

15、ehold working or in school, there is often no one at home who can care for a sick or weak person. To meet Bthis need/B, a great many nursing homes and convalescent hospitals have been built. These are often profit-making organizations, although some are sponsored by religious and other nonprofit gro

While a few of these institutions are good, most of them are simply dumping grounds for the dying in which care is given by poorly paid, overworked, and underskilled personnel.The writer believes that the population explosion results from Aan increase in birthrates.Bthe industrial development.C

17、a decrease in death rates.Dcultural advances. 5.B第三篇/B BPlant Gas/B Scientists have been studying natural sources of methane for decades but hadnt regarded plants as a producer, notes Frank Keppler, a geochemist at the Max Planck Institute for Nuclear Physics in Heidelberg, Germany. Now Keppler and

18、his colleagues find that plants, from grasses to trees, may also be sources of the greenhouse gas. This is really surprising, because most scientists assumed that methane production requires an oxygen-free environment. Previously, researchers had thought that it was impossible for plants to make sig

19、nificant mounts of the gas. They had assumed that microbes need to be in environments without oxygen to produce methane. Methane is a greenhouse gas, like carbon dioxide. Gases such as methane and carbon dioxide trap heat in Earths atmosphere and contribute to global warming. In its experiments, Kep

20、plers team used sealed chambers that contained the same concentration of oxygen that Earths atmosphere has. They measured the amounts of methane that were released by both living plants and dried plant material, such as fallen leaves. With the dried plants, the researchers took measurement at temper

21、atures ranging from 30 degrees Celsius to 70 degrees C. At 30 degrees C, they found, a gram of dried plant material released up to 3 nanograms of methane per hour. ( One nanogram is a billionth of a gram. ) With every 10-degree rise in temperature, the amount of methane released each hour roughly do

22、ubled. Living plants growing at their normal temperatures released as much as 370 nanograms of methane per gram of plant tissue per hour. Methane emissions tripled when living and dead plant was exposed to sunlight. Because there was plenty of oxygen available, its unlikely that the types of bacteri

23、a that normally make methane were involved. Experiments on plants that were grown in water rather than soil also resulted in methane emissions. Thats another strong sign that the gas came from the plants and not soil microbes. The new finding is an interesting observation, says Jennifer Y. King, a b

24、iogeochemist at the University of Minnesota in St. Paul. Because some types of soil microbes consume methane, they may prevent plant-produced methane from reaching the atmosphere. Field tests will be needed to assess the plants influence, she notes.What was scientists understanding of methane AIt wa

26、plored. Now, Scientists at the Woods Hole Oceanographic Institution (WHOI) in Massachusetts are building an underwater vehicle that will carry explorers as deep as 6,500 meters (21,320 feet). The new machine, known as a manned submersible or human-operated vehicle (HOV), will replace another one nam

27、ed Alvin which has an amazing record of discovery, playing a key role in various important and famous undersea expeditions. Alvin has been operating for 40 years but can go down only 4,500 meters (14,784 feet). Its about time for an upgrade, WHOI researchers say. Alvin was launched in 1964. Since th

28、en, Alvin has worked between 200 and 250 days a year, says Daniel Fornari, a marine geologist and director of the Deep Ocean Exploration Institute at WHOI. During its lifetime, Alvin has carried some 12,000 people on a total of more than 3,000 dives. A newer, better versions of Alvin is bound to rev

29、eal even more surprises about a world that is still full of mysteries, Fornari says. It might also make the job of exploration a little easier. We take so much for granted on land, Fomari says. We can walk around and see with our eyes how big things are. We can see colors, special arrangements. Size

30、-wise, the new HOV will be similar to Alvin. Itll be about 37 feet long. The setting area inside will be a small sphere, about 8 feet wide, like Alvin, itll carry a pilot and two passengers. It will be just as maneuverable. In most other ways, it will give passengers more opportunities to enjoy the

31、view, for one thing. Alvin has only three windows, the new vehicle will have five, with more overlap so that the passengers and the pilot can see the same thing. Alvin can go up and down at a rate of 30 meters every second, and its maximum speed is 2 knots ( about 2.3 miles per hour), while the new

32、vehicle will be able to ascend and descend at 44 meters per second. Itll reach speeds of 3 knots, or 3.5 miles per hour.What is Alvin AA research institute.BA transporting vehicle.CA submersible.DA scientist. 7.阅读下面的短文，文中有15处空白，每处空白给出了4个选项，请根据短文的内容从4个选项中选择1个最佳答案。 BAn Intelligent Car/B Driving needs
