Our Future Homes
　What kinds of homes will we live 1 the future? Nobody can be sure, 2 architects, and scientists are 3 new ideas now.
　　Some architects are thinking about 4 whole cities under huge glass domes. Of course, complicated heating and 5 systems will be necessary to control the climate in the domes. 6, there will never be any rain 7snow, and the temperature will be always 8.
　　Perhaps everyone will live in vertical（立体的） 9. High rises are so large that they can contain all the necessities of life. Since vertical cities will use 10 land than horizontal cities, and provide homes for more people, they will be 11 for small countries that have12 populations.
Another idea that will be helpful to 13 countries (and island countries) is
the 14 city. Monaco has already built homes, stores, and offices 15 the water of the Mediterranean Sea. And a Japanese 16 has made a plan for constructing buildings on bridges over Tokyo Bay.
　　There are some people who think we will go back to living in 17. But the caves of the future will be quite 18 the caves of the Stone Age. Computers will control light and climate. Farms and parks will be on the land 19 the cave city. When people want to go to the country or to a park, a short ride in 20 will take them there.

In 1886 explorer Robert Peary traveled to Greenland for the U.S. Navy. Before his journey, no one knew Greenland’s size or shape. On Peary’s first trips, he explored Greenland, mapping parts of it.
When Peary returned to the United States, he went to a businessman to sell some furs. There he met Matthew Henson, an African American mechanic, builder and navigator. When Peary went to Nicaragua on a Navy mission(任务),Henson went with him. When that job was over, the two headed to the Arctic.
Henson and Peary set sail for Greenland. When they landed, Henson built a house for their base camp. Peary and his men set out to explore the land by dog sledge(雪橇). Henson was injured and had to stay at the base. While there, he made friends with the Inuit, the native people.
In 1895 Henson, Peary and Hugh Lee went out on another dog sledge journey. This time, they found Greenland’s northernmost point. They now knew that the North Pole lay under the frozen Arctic Ocean. Peary had hoped to cross the ice. but the group ran out of food and returned to base camp. In the years that followed, Peary and Henson tried several times to reach the North Pole, but each time they failed. On one trip, Peary’s feet froze, and he lost his toes（脚趾）.
Peary and Henson planned last trip when Peary was 53 years old. They started across the sea ice from Ellesmere Island, which is located（位于） north of Canada. The temperature dropped as low as—51 degrees Celsius. The explores’ cheeks froze , and they suffered snow blindness from the sun’s glare. They experienced high winds and storms, and they also faced a hidden danger. Under the frozen ocean were powerful currents（潮流）. The ice moved and broke apart leaving open water, called leads. Twice Peary fell into leads. But eventually he and Henson became the first persons to reach the North Pole.
【小题1】 What did Peary and Henson find in 1895?

Even plant can run a fever, especially when they’re under attack by insects or disease. But unlike human, plants can have their temperature taken from 3,000 feet away straight up. A decade ago, adopting the infrared （红外线）scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide (杀虫剂)spraying rather than rain poison on a whole field, which invariably includes plants that don’t have pest(害虫)problems.

Even better, Paley’s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured the heat sent out by crops. The data were transformed into a color-coded map showing where plants were running “fevers”. Farmers could then spot-spray, using 50 to 70 percent less pesticide that they otherwise would.

The bad news is that Paley’s company closed down in 1984, after only three years. Farmers resisted the new technology and long-term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements（改进）ininfrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. “This technique can be used on 75 percent of agricultural land in the United States,” says George Oerther of Texas A& M, who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain 10 years ago.

If your head is overheating, you are very likely to yawn(打哈欠) soon, according to a new study that has found the main purpose of yawning is to control brain temperature. The study explains several mysteries about yawning, such as why it’s most commonly done just before and after sleeping, why certain diseases lead to too much yawning, and why breathing though the nose often stops yawning.
“Brains are like computers,” Andrew Gallup, a researcher in the department of Biology at Binghamton University who led the study, said. “They operate best when cool.”
He and his co-workers Micheal Miller and Anne Clark did researches on yawning in parakeets(长尾小鹦鹉) , which have relatively large brains, live wild in Australia, often experience temperature changes, and, most importantly, do not yawn when others yawn, as humans and some other animals do.
For the study, the scientists put parakeets under three different conditions: increasing temperature, high temperature and normal temperature. While the frequency(频率) of yawns did not increase under the latter two conditions, it increased greatly when the researchers increased the temperature.
It’s now believed yawning operates like a radiator(散热器).
If air in the atmosphere is cooler than the brain and body temperatures, taking it in quickly cools blood, which in turn cools the brain. The new findings also explain why tired people often yawn. Both tiredness and sleep loss can increase brain temperature, while yawning can cool down the brain.
In the future, researchers may focus more on brain temperature and its role in diseases and their symptoms. But the new study on yawning changes the popular idea that yawns are just signs of getting tired of something.

第三部分：阅读理解（共20小题，每题2分，满分40分）
阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。
A
We bet that on cold wintry days, many of you love to stay in your warm home and, every now and then, come out into the kitchen for a snack. Unfortunately, plenty of creepy-crawly critters(爬行生物) like to do the same thing!
Winter is the time when bugs (虫子) invade your house without an invitation. The season can be tough for such creatures. In winter the air is cold, the ground is hard and many trees have no leaves. So bugs do what they have to do to survive.
Monarch butterflies head south to warmer climates. Ants crowd in deep underground colonies and eat food they have been storing all year. Many insects go into a deep sleep called diapause. There’re different kinds of diapause, but all are similar to hibernation, a time when bigger animals become inactive in the cold. Insects go into an inactive period, too, but it often isn’t when the temperature drops.
They rely on more dependable signals in the environment. For example, many insects can tell how much sunlight there’s each day. They use that to tell them when to shut down. Bugs are cold-blooded, meaning that their inside temperature is the same as the outside. They can’t move much when it gets below 40 degrees Fahrenheit. So they search for any warm place.
They’re looking for protection. These guys have been doing this for 300 million years, so they don’t really know they’re coming into your house. The home is a recent event in terms of their evolutionary behavior. They enter through tiny cracks or come in unnoticed on your clothes or shoes. Remember that they may be invading your homes for warmth and food, but they don’t care about humans.
56. What is the purpose of the first paragraph?
A. To point out that humans like to stay at home in winter.
B. To mean that humans and bugs have the same living habits.
C. To mean that bugs will invade the house for their winter.
D. To put forward the idea that bugs are not welcome in winter.
57. According to the text, what is diapause?
A. It is the same as the animals’ hibernation.
B. It often appears in warm areas all the year.
C. It is done to keep bugs active in winter.
D. It is a deep sleep similar to hibernation.
58. What often decides bugs’ diapause?
A. The lower local temperatures.           B. The amounts of sunlight.
C. Kinds of environmental signals.         D. The insects’ inside temperature.
59. According to the text, bugs invade humans’ homes to ______.
A. attack humans                                 B. look for enough food
C. seek for protection                           D. show their evolutionary results
60. What would be the best title for the text?
A. Bugs’ life on cold wintry days
B. Why bugs invade your home in winter?
C. Good relations between humans and bugs
D. What does diapause mean?
