2、Better Control of TB Seen if a Faster Cure is FoundThe 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 ______. 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 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.【单选题】

3、HalloweenHalloween is an autumn holiday that Americans celebrate every year. It means "holy evening", and it comes every October 31, the evening before All-Saints Day. It used to be thought the most wonderful night of the year. It was the night when witches and evil spirits came back on earth. People kept up many strange old customs in an effort to keep these evil things away. Farmers used to light big fires in their fields, and the farm workers and their families would walk around the fields singing old songs. Sometimes they would stop to hear the local priest offer prayers to the good spirits, and ask them to help keep the evil ones away. Great care was taken that none of the farm animals were left in the fields. They would all be locked up safely in their stables, and over each of the stable doors a few rowan leaves would be hung. Witches and evil spirits would not go anywhere near the rowan tree. In more recent times, Halloween has become a time for the parties, when children dress up as witches and play all kinds of special games. After the games there is often a big supper with plenty of pumpkin pie, cakes and a lot of other delicious things to eat. But for the most part the children enjoy the fun of dressing up and playing their favorite game of "Trick or Treat". They run down each street knocking on the doors crying loudly "Trick or Treat! Money or eat!", and most people have some sweets or money ready to give them. Those that do not can expect maybe to have a tyre flattened, or their windows covered in soap. Or the children may just knock on the door and run away. Some children think of other people on Halloween. They carry boxes for UNICEF (The United Nations International Children\'s Emergency Fund). They ask for money to help poor children all around the world. Of course, every time they help UNICEF, they usually receive a treat for themselves, too. Every autumn, when the vegetables are ready to eat, children pick large orange pumpkins. Then they cut faces in the pumpkins and put lights inside. It looks like there is a person looking out of the pumpkin! These lights are called jack-o\'-lanterns, which means "Jack of the lantern". But in this modern age many of the pumpkins are being replaced with plastic electric ones that can be brought out each year. What did priests do on Halloween?【单选题】

A.They helped farmers light fires and sang songs.

B.They prayed to the good spirits and asked them to help keep the evil ones away.

C.They took care of farm animals for farmers.

D.They played games with children.

正确答案:B

答案解析:由第1段最后一句可知，有时农夫停下去听当地牧师向天使精灵作祷告，请求他们帮助赶走邪恶精灵。因此选B。

4、Inventor of LEDWhen Nick Holonyak set out to create a new kind of visible lighting using semiconductor alloys, his colleagues thought he was unrealistic. Today, his discovery of light-emitting diodes, or LEDs, are used in everything from DVDs to alarm clocks to airports. Dozens of his students have continued his work, developing lighting used in traffic lights and other everyday technology. On April 23,2004, Holonyak received the $500,000 Lemelson-MIT Prize at a ceremony in Washington. This marks the lOth year that the Lemelson-MIT Program at the Massachusetts Institute of Technology (MIT) has given the award to prominent inventors. "Anytime you get an award big or little. It\'s always a surprise. " Holonyrak said. Holonyak, 75, was a student of john Bardeen, an inventor of the transistor, in the early 1950s. After graduate school, Holonyak worked at Ben Labs. He later went to General Electric, where he invented a switch now widely used in house dimmer switches. Later, Holonyak started looking into how semiconductors could be used to generate light. But while his colleagues were looking at how to generate invisible light, he wanted to generate visible light. The LEDS he invented in 1962 now last about 10 times longer than incandescent bulbs, and are more environmentally friendly and effective. Holonyak, now a professor of electrical and computer engineering and physics at the University of Illinois, said he suspected that LEDs would become as commonplace as they are today, but didn\'t realize how many uses they would have. "You don\'t know in the beginning. You think you\'re doing something important. You think it\'s worth doing, but you really can\'t tell what the big payoff is going to be, and when, and how. You just don\'t know, "he said. The Lemelson. MIT Program also recognized Edith Flanigen, 75, with the $100,000 Lemelson-MIT Lifetime Achievement Award for her work on a new generation of "molecular sieves", that can separate molecules by size. Holonyak believed that LEDs would become very popular in the future.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:题干中出现的核心词popular作为答案线索，文章中并没有出现popular这个词。注意文章中描述Holonyak态度的句子，找到答案相关句，揭示suspect的含义应该是“猜想”，因此整个画线句的内容（他曾猜想到LEDS的用途会非常普遍，就像现在这样子）与问题句的内容一致，选A。

5、The Hurricane1. A hurricane (飓风) is a tropical storm with winds that have reached a constant speed of 74 miles per hour. Hurricane winds blow in a large spiral(螺旋) around a relative calm center known as the "eye". The "eye" is generally 20 to 30 miles wide, and the storm may extend outward 400 miles. As a hurricane nears land, it can bring heavy rains, high winds and storm surges(风暴潮). The storm surges and heavy rains can lead to flooding.2. Hurricanes are given a different label, depending on where they occur. If they begin over the North Atlantic Ocean, the Caribbean Sea, The Gulf of Mexico, or the Northeast Pacific Ocean, they are called hurricanes. Similar storms that occur in the Northwest Pacific Ocean west of the Internaional Date Line are called typhoons near Australia and in the Indian Ocean, they are referred to as tropical cyclones(龙卷风).3. When a hurricane hits land, it can do great damage through its fierce winds, heavy rains, inland(内陆的) flooding and huge waves crashing on to the shore. During a hurricane, homes, businesses and public buildings may be damaged or destroyed, roads and bridges can be washed away. A powerful hurricane can kill more people and destroy more property than any other natural disaster. Fishermen are at special risk from hurricanes as they may be at sea when a hurricane arrives and not be able to get to a safe harbor if they do not receive adequate warning.4. If a hurricane is comming in your area, the most important thing is to stay calm and find shelter immediately. Go to your safe room. If you do not have one, stay indoors during the hurricane and go to a safer place near the center of your home. Cover yourself with a blanket and be sure to keep away from windows and glass doors, because if the glass breaks it’s really dangerous. Do not be fooled if there is lull(暂停), it could be the eye of the storm—winds will pick up again.Paragraph 3 ______【单选题】
