1、The Value of Advertisement
Money spent on advertising is worth spending. It serves directly to bring about a rapid sale of goods at reasonable prices, so setting up a firm home market and making it possible to provide for export at good price. By drawing attention to new ideas it helps greatly to raise standards of living. By helping to increase demand it causes an increased need for labor, and is therefore a nice way to fight unemployment. It lowers the costs of many services: without advertisements your daily newspaper would cost four times as much, the price of your television program would need to be doubled, and travel by bus or subway would cost more.
And perhaps most important of all, advertising provides a promise of reasonable value in the products and services you buy. Besides the fact that twenty-seven Acts of Parliament govern the terms of advertising, no regular advertiser dare produce anything that fails to live up to the promise of his advertisements. He might fool some people for a little while through misleading advertising. He will not do so for long, for the public has the good sense not to buy the poor goods more than once. If you see a product frequently advertised, it is the proof I know that the product does what is promised for it, and that it has good value.
Advertising does more for the good of the public than any other force I can think of.
There is one more point I feel I ought to touch on. Recently I heard a well-known television person declare that he was against advertising because it persuades rather than informs. He was telling us the real difference. Of course advertising tries to persuade.
If its messages were nothing but information, that would be difficult to get more people to buy, for even the choice of the color of a shirt is a bit persuasive-advertising would be so boring that no one would pay any attention. But perhaps that is what the well-known television person wants.
From the first paragraph we can see the writer believes that____.
【單選題】

A.advertisements are worth reading

B.money spent on advertising is worthless

C.it is worthwhile spending money on a lot of things

D.to spend money on advertising is worthwhile

正確答案:D

答案解析:第1句是主題句,花在廣告上的錢(qián)是值得花的。接下的句子對(duì)是這一句的進(jìn)一步闡述。因此答案是D。

2、Weaving with Light
In the Sierra Madre mountain range of west central Mexico, the native Huichol people live much the way their ancestors did-without electricity. That's because it's too expensive to string power lines to the remote mountain areas where they live. To help support themselves, the Huichol create beautiful artwork. They sell their art in cities hundreds of miles away from their villages. And without electricity, at home or on the road, they can only work during daylight hours. When it gets dark, they must stop whatever they're doing.
Now, a team of scientists, designers and architects is using new technologies to provide the Huichol with light after the sun sets. The scientists technique involves weaving tiny electronic crystals into fabrics that can be made into clothes, bags, or other items.
By collecting the sun's energy during the day, these lightweight fabrics provide bright white light at night. Their inventors have named the fabrics "Portable Lights," Portable Lights have the potential to transform the lives of people without electricity around the world, says project leader Sheila Kennedy.
"Our invention," Kennedy says, "came from seeing how we could transform technology we saw every day in the United States and move it into new markets for people who didn't have a lot of money."
At the core of Portable Light technology are devices called high - brightness light - emitting diodes, or HB LEDs. These tiny lights appear in digital clocks, televisions and streetlights.
LEDs are completely different from the light bulbs. Most of those glass bulbs belong to a type called incandescent lights. Inside, electricity heats a metal coil to about 2,200 degrees Celsius. At that temperature, bulbs give off light we can see.
Ninety percent of energy produced by incandescent lights, however, is heat and invisible. With all that wasted energy, bulbs burn out quickly. They are also easily broken.
LEDs, on the other hand, are like tiny pieces of rock made up of molecules that are arranged in a crystal structure. When an electric current passes through an LED, the crystal structure produces light. Unlike incandescent bulbs, they can produce light of various colors. Within an LED, the type of molecules and their particular arrangement determines what color is produced.
All of the following are disadvantages of incandescent lights EXCEPT that ______.【單選題】

A.they are not bright enough

B.they burn out quickly

C.they are easily broken

D.they waste most of the energy produced

正確答案:A

答案解析:本題難度較大,需要通讀全文,尋找答案依據(jù)。通讀全文可以發(fā)現(xiàn),只有they are not bright enough是文章未提到的,答案是A。

3、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 (極地的) 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.
Some industrialized countries are unwilling to spend money in reducing pollution.
【單選題】

A.Right

B.Wrong

C.Not mentioned

正確答案:C

答案解析:題干大意:一些工業(yè)化國(guó)家不愿意花錢(qián)減少污染。文章最后一句提到:All they can do is to hope that industrialized countries will take steps to reduce pollution. 所有他們能做的就是希望工業(yè)化國(guó)家能采取措施減少污染。但是這并沒(méi)有說(shuō)明工業(yè)化國(guó)家不愿意花錢(qián)減少污染。故答案選C。

4、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(斷層) lines run through the San Francisco area. Faults are places where pieces of Earth's crust (地殼) 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(斷裂) 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 (脈沖) 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.
The highest speed of fault ruptures in the 1906 quake was more than 3,5 kilometers per second.【單選題】

A.Right

B.Wrong

C.Not mentioned

正確答案:A

答案解析:本題難度不大,找到答案依據(jù)不難。答案依據(jù)在第三段。第三段最后一句:During bigger quakes, however, ruptures can happen at rates faster than 3.5 kilometers per second.談到在更大的地震中,斷裂速度可以高于3.5千米每秒。所以本題正確,答案是A。

5、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 ______ 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 developed 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.
