2、The Threat to Kiribati
The people of Kiribati are afraid that one day in the not-too-distant future, their country will disappear from the face of the earth-literally. Several times this year, the Pacific island nation has been flooded by a sudden high tide. These tides, which swept across the island and destroyed houses, came when there was neither wind nor rain. "This never happened before," say the older citizens of Kiribati.
What is causing these mysterious high tides? The answer may well be global warming. When fuels like oil and coal are being burned, pollutants (污染物) are released. These pollutants trap heat in the earth's atmosphere. Warmer temperatures cause water to expand and also create more water by melting glaciers (冰川) and polar (极地的) ice caps.
If the trend continues, scientists say, many countries will suffer, Bangladesh, for example, might lose one-fifth of its land. The coral (珊瑚) island nations of the Pacific, like Kiribati and the Marshall Islands, however, would face an even worse fate-they would be swallowed by the sea. The loss of these coral islands would be everyone's loss. Coral formations are home to more species than any other place on earth.
The people of these nations feel frustrated. The sea, on which their economies have always been based, is suddenly threatening their existence. They don't have the money for expensive technological solutions like seawalls. And they have no control over the pollutants, which are being released mainly by activities in large industrialized countries. All they can do is to hope that industrialized countries will take steps to reduce pollution.
The coral island nations of the Pacific have a long history of civilization.
【单选题】
A.Right
B.Wrong
C.Not mentioned
正确答案:C
答案解析:题干大意:太平洋的珊瑚岛国有很长的文明历史。文章第三段提到:The coral (珊瑚) island nations of the Pacific. 文中提到了太平洋的珊瑚岛国,但是并没有提到它们有很长的文明历史。故答案选C。
3、Houses of Future
What will houses be like in thirty years' time? No one really knows, but architects are trying to predict ______.
Future houses will have to be flexible. In thirty years' time even more of us will be working at home. So we will have to be able to use areas of the house for work for part of the day and for living for the rest. Families grow and change with children arriving, growing up and leaving home. The house ofthe future will have to grow and change with the familyF, nothing will be as fixed as it is now. The house will always be changing to meet changing needs.
Everyone agrees that in thirty years' time we will be living in "intelligent" houses. We will be able to talk to our kitchen machines and discuss with them what to do. Like this, "we'll be having a party this weekend. What food shall we cook?" And the machine will tell us what food we will have to buy and how to cook it. We will be able to leave most of the cooking to the machines, just tasting things from time to time to check.
The house of the future will be personal-each house, you will be able to change the color ofthe wall easily, you won't have to paint them, you'll be able to tell the wall to change the color! And if you don't like the color the next day, you will be able to have a new one. The only thing you won't be able to do is moving the house somewhere else.
【单选题】
A.you will be able to change the color ofthe wall easily
B.The only thing you won't be able to do is moving the house somewhere else
C.And the machine will tell us what food we will have to buy and how to cook it
D.what our home will be likeE
E.The house ofthe future will have to grow and change with the familyF
F.he kids might take their bedrooms with them as they have
正确答案:D
答案解析:意思是“我们未来的房子会是如何呢”,刚好与第1段第1句相对应。
4、Better Control of TB Seen if a Faster Cure is Found
The World Health Organization estimates that about one-third of all people are infected with bacteria that cause tuberculosis. Most times, the infection remains inactive. But each year about eight million people develop active cases of TB, usually in their lungs. Two million people die of it. The disease has increased with the spread of AIDS and drug-resistant forms of tuberculosis.
Current treatments take at least six months. Patients have to take a combination of several antibiotic drugs daily. But many people stop as soon as they feel better. Doing that can lead to an infection that resists treatment. Public health experts agree that a faster-acting cure for tuberculosis would be more effective. Now a study estimates just how effective it might be. A professor of international health at Harvard University led the study. Joshua Salomon says a shorter treatment program would likely mean not just more patients cured. It would also mean fewer infectious patients who can pass on their infection to others.
The researchers developed a mathematical model to examine the effects of a two-month treatment plan. They tested the model with current TB conditions in Southeast Asia. The scientists found that a two-month treatment could prevent about twenty percent of new cases. And it might prevent about twenty-five percent of TB deaths. The model shows that these reductions would take place between two thousand twelve and two thousand thirty. That is, if a faster cure is developed and in wide use by two thousand twelve.
The World Health Organization ______the DOTS program in nineteen ninety. DOTS is Directly Observed Treatment, Short-course. Health workers watch tuberculosis patients take their daily pills to make sure they continue treatment.
Earlier this year, an international partnership of organizations announced a plan to expand the DOTS program. The ten-year plan also aims to finance research into new TB drugs. The four most common drugs used now are more than forty years old. The Global Alliance for TB Drug Development says its long-term goal is a treatment that could work in as few as ten doses.
【单选题】
A.developed
B.invented
C.delayed
D.refused
正确答案:A
答案解析:空白处的上一句实际上也起到了提示作用,可以推测,本句应该是“制订DOTS计划”,而4个选项中只有A有“制订”的意思,计划也不可能是“发明”,从上下文分析,更不可能是“推迟”或“拒绝”。
5、Lakes, Too, Feel Global Warming
There's no doubt, In the last few decades, the average temperature on Earth has been higher than it has been in hundreds of years. Around the world, people are starting to measure the effects of global warming and trying to figure out what to do about it.
Scientist recently used satellites to study the temperatures of lakes around the world and they found that lakes are heating up. Between 1985 and 2009, satellites recorded the night time temperatures of the surfaces of 167 lakes. During those 24 years, the lakes got warmer by an average of about 0.045 degree Celsius per year.
In some places, lakes have been warming by as much as 0.10 degree Celsius per year. At that rate, a lake may warm by a full degree Celsius in just 10 years. That difference may seem small you might not even notice it in your bath. But in a lake, slightly warmer temperatures could mean more algae (水藻) and algae can make the lake poisonous to fish.
The study shows that in some regions, lakes are warming faster than the air around them. This is important because scientists often use measurements of air temperature to study how Earth is warming. By using lake temperatures as well, scientists can get a better picture of global warming. The scientists say data on lakes give scientists a new way to measure the impact of climate change around the world.
That's going to be useful, since no matter the country is too big or too small can't ignore climate changes. Scientists aren't the only ones concerned. Everyone who lives on Earth is going to be affected by the rapid warming of the planet. Many world leaders believe we might be able to do something about it, especially by reducing the amount of greenhouse(温室) gases we put into the air.
That's why the United Nations started the Framework Convention on Climate Change, or UNFCCC. Every year the convention meets, and representatives from countries around the world gather to talk about climate change and discuss global solutions to the challenges of a warming world.
Global warming is less threatening to small countries.

7、What Is the Coolest Gas in the Universe?
What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was - 91℃, which occurred in Antarctica (南极洲) in 1983.
We encounter an interesting situation when we discuss temperatures in space.
Temperatures in Earth orbit actually range from about +120℃ to - 120℃. The temperature depends upon _____ you are in direct sunlight or shade. Obviously, -120℃ is colder than our body can safely endure. Thank NASA science for well, de signed space suits that protect astronauts from these temperature extremes.
The space temperatures just discussed affect only our areal of the solar system. Obviously, it is hotter closer to the Sun and colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about - 210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly impossible to have a temperature below absolute zero, which is - 273℃, at which atoms do not move. Two scientists, whose names are Cornell and Wieman, have successfully cooled down a gas to a temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 for their work, not a discovery, in this case.
Why is the two scientists' work so important to science?
In the 1920s, Satyendra Nath Bose was studying an interesting theory about special light particles we now call photons (光子). Bose had trouble convincing other scientists to believe his theory, so he contacted Albert Einstein. Einstein's calculations helped him theorize that atoms would behave as Bose thought—but only at very cold temperatures.
Scientists have also discovered that ultra - cold(超冷) atoms can help them make the world's atomic clocks even more accurate. These clocks are so accurate today they would only lose one second every six million years! Such accuracy will help us travel in space because distance is velocity times time 4 ( d = v×t). With the long distances involved in space travel, we need to know time as accurately as possible to get accurate distance.

9、A Great Quake Coming?
Everyone lives in San Francisco knows that earthquakes are common in the Bay Area and they can devastate. In 1906, for example, a major quake destroyed about 28000 buildings and killed hundreds, perhaps thousands of people. Residents now wonder when will the next "Big One" strike. It's bound to happen someday. At least seven active fault(断层) lines run through the San Francisco area. Faults are places where pieces of Earth's crust (地壳) slide past each other. When these pieces slip, the ground shakes.
To prepare for that day, scientists are using new techniques to reanalyze the 1906 earthquake and predict how bad the damage might be when the next one happens.
One new finding about the 1906 quake is that the San Andreas Fault split apart faster than scientists had assumed at the time. During small earthquakes, faults rupture(断裂) about 2.7 kilometers persecond. During bigger quakes, however, ruptures can happen faster than 3.5 kilometers persecond.
At such high speeds, massive amounts of pressure build up, generating underground waves that can cause more damage than the quake itself. Lucky for San Francisco, these pressure pulses (脉冲) traveled away from the city during the 1906 event.
Looking ahead, scientists are trying to predict when the next major quake will occur. Records show that earthquakes were common before 1906. Since then, the area has been relatively quiet. Patterns in the data, however, suggest that the probability of a major earthquake striking the Bay Area before 2032 is at least 62 percent.
New buildings in San Francisco are quite safe in case of future quakes. Still, more than 84 percent of the city's buildings are old and weak. Analyses suggest that another massive earthquake would cause extensive damage.
People who live there today tend to feel safe because San Francisco has remained pretty quiet for a while. According to the new research, however, it's not a matter that whether "the Big One" will hit here. It's just a matter of when.
Earthquakes rarely happened in San Francisco before 1906.【单选题】
A.Right
B.Wrong
C.Not mentioned
正确答案:B
答案解析:本题难度不大,找到答案依据不难。答案依据在第五段。第五段第二句:Records show that earthquakes were common before 1906.谈到记录显示在1906年前地震十分常见的。所以本题错误,答案是B。
