1、One Good Reason to Let Smallpox LiveIt\'s now a fair bet that we will never see the total extinction (灭绝) of the smallpox (天花) virus. When smallpox was completely got rid of in the world, scientists wanted to destroy the killer virus in the last two labs, one in the US and one in Russia. They asked: If smallpox has truly gone from the planet, what point was there in keeping these reserves?In reality, of course, it was naive to imagine that everyone would let go of such a powerful potential weapon. Undoubtedly several nations still have a few vials (小药瓶). and the last "official" stocks of live Virus bred mistrust of the US and Russia, forno obvious gain.Now American researchers have found an animal model of the human disease, opening the way fortests on new treatments and vaccines(疫苗). So once again there\'s a good reason to the virus, just in keep the disease puts in a reappearance.How do we _____ with the mistrust of the US and Russia? deal. Keep the virus Simple international support in a well - guarded UN laboratory that\'s open to all countries. The US will object, of course, just as it with a multilateral (多边的) approach to just about everything. But it doesn\'t mean the idea is rejects. If the virus is useful, then let\'s wrong it the servant of all humanity make not just a part of it.【单选题】
A.need
B.time
C.fact
D.case
正确答案:D
答案解析:本题有一定难度,考查in case的用法,in case指“以免,以防”,文章此处是说“……以免这种病毒卷土重来”,答案是D。
2、Lakes, Too, Feel Global WarmingThere\'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 ortoo 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, orUNFCCC. 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.The temperatures of lakes around the world have increased greatly between 1985 - 2009.【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,答案依据比较明显,在文章第二段第三句:During those 24 years, the lakes got warmer-by an average of about 0.045 degree Celsius per year.很明显,每年湖水的温度平均才上升0. 045度,题干却说have increased greatly,和原文句意明显不符,答案是B。
3、She can be relied on in a crisis.【单选题】
A.looked after
B.believed in
C.turned on
D.depended on
正确答案:D
答案解析:在危机时她还是可靠的。本题有一定难度,B的干扰性最大,但在确定词的精确意义后,可以发现,relied on和depended on都是“可以依靠的”意思,所以D是最佳答案。
4、Dung to DeathFields across Europe are contaminated with dangerous levels of the antibiotics given to farm animals. The drugs, which are in manure sprayed onto fields as fertilizers, could be getting into our food and water, helping to create a new generation of antibiotic-resistant "superbugs". The warning comes from a researcher in Switzerland who looked at levels of the drugs in farm slurry His findings are particularly shocking because Switzerland is one of the few countries to have banned antibiotics as growth promoters in animal dead.Some 20,000 tons of antibiotics are used in the European unionand the US each year. More than half are given to farm-animals to prevent disease and promote growth. ______Most researchers assumed that humans become infected with the resistant strains by eating contaminated meat. But far more of the drugs end. up in manure than in meat products, says Stephen Mueller of the Swiss Federal Institute forEnvironmental Science and Technology in Dubendorf. and manure contains especiaily high levels of bugs that are resistant to antibiotics he says.With millions of tons of animals manure spread onto fields of crops such as wheat and barley each year, this pathway seems an equally likely route forspreading resistance, he said. The drugs contaminate the crops, which are then eaten. They could also be leaching into tap water pumped from rocks beneath fertilized fields.Mueller is particularly concerned about agroupof antibiotics called sulphonamides. They do not easily degrade ordissolve in water. His analysis found that Swiss farm manure contains a high percentage of sulphonamides; each hectare of field could be contaminated with up to 1 kilogram of the drugs. This concentration is high enough to trigger the development of resistance among bacteria. But vets are not treating the issue seriously. There is growing concern at the extent to which drugs, including antibiotics, are polluting the environment. Many drugs given to humans are also excreted unchanged and are not broken down by conventional sewage treatment.【单选题】
A.They do not easily degrade ordissolve in water.
B.and manure contains especiaily high levels of bugs that are resistant to antibiotics he says.
C.Animal antibiotics is still an area to which insufficient attention has been paid
D.But recent research has found a direct link between the increased use of these farmyard drugs and the appearance of antibiotic-resistant bugs that infect people.
E.His findings are particularly shocking because Switzerland is one of the few countries to have banned antibiotics as growth promoters in animal dead.
F.They could also be leaching into tap water pumped from rocks beneath fertilized fields.
正确答案:D
答案解析:前两句讲的是抗生素在欧洲和美国的大量使用,选项D讲的是由此导致的不良后果,接上去是最合理不过的。But明确地表明了这一转折。
5、A Star Is Born1 The VLT (Very Large Telescope) is the world\'s largest telescope and is taking astronomers further back to the Big Bang than they ever thought possible. Located 2,600 meters up to the Chilean Andes, it has four huge mirrors, each about the size of a London bus. The VLT is so powerful it can spot a burning match 10, 000 kilometers away. 2 This astonishing power will allow astronomers to see events in space from the birth of stars to the collision of galaxies on the edge of the cosmos. The VLT is giving astronomers their best ever view of the cosmos. The power of the VLT to see the smallest detail at the furthest distances makes its designers amazed. 3 Take the case of Eta Carinae, one of the most explosive stars in the universe. This star produces ultraviolet laser rays (紫外线) and it will destroy itself in a few million years\' time. It is five times brighter than the sun and when it explodes it is going to be a sight worth waiting for. 4 But it is at distances of millions, even billions, of light years that the VLT really shows its power. The VLT can detect light that setout on its journey before the earth even existed. This gives astronomers their first ever detailed views of events that took place in the earliest days of the cosmos. 5 In other words, the VLT is a kind of a time machine. It takes astronomers back to a time when complete galaxies crashed into each other. The effects of these past collisions can now be seen by scientists, and astronomers believe the telescope will reveal more about these exciting events in the years to come. One day, we might be able to say we have traveled back to the beginning of time, and we will have a much clearer picture of how our planet was born. Paragraph 1____【单选题】
A.Events That Took place Before the Earth Existed
B.Power of the Telescope
C.Details of Eta Carinae
D.Invention of a Time Machine
E.Biggest Telescope
F.Ultraviolet Laser Rays
正确答案:E
答案解析:文章第1段主要介绍的是世界上最大的望远镜的大小,故E为正确答案。
6、Weaving with LightIn 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 oron 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, orother 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 forpeople who didn\'t have a lot of money."At the core of Portable Light technology are devices called high - brightness light - emitting diodes, orHB 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 coloris produced.The central part of the Portable Lights technology is ______.【单选题】
A.glass bulbs
B.digital clocks
C.incandescent lights
D.HB LEDs
正确答案:D
答案解析:本题有一定难度,关键在吃透句意,答案依据比较明显,带着题干信息词回文章定位,答案依据主要在文章第五段第一句:At the core of Portable Light technology are devices called high - brightness light - emitting diodes orHB LEDs。其中core和题干里的central part是同义词,回来看选项,D项和原文句意相符,答案是D。
7、Snow RangerThe two things, snow and mountains, which are needed fora ski area are the two things that cause avalanches, large mass of snow and ice crushing down the side of a mountain, often called "White Death. "It was the threat of the avalanche and its record as a killer of man in the western mountains that created the snow ranger. He first started on avalanche control work in the winter of 1937, 38 at Alta, Utah, in Wasatch National Forest. This mountain valley was becoming well known to skiers. It was dangerous. In fact, more than 120 persons had lost their lives in 1936 and another 200 died in 1937 as a result of avalanches before it became a majorski area. Thus, development of Alta and other majorski resorts in the west was dependent upon controlling the avalanche. The Forest Service setout to do it, and did with its corps of snow rangers. It takes many things to make a snow ranger. The snow ranger must be in excellent physical condition. He must be a good skier and a skilled mountain climber. He should have at least a high school education, and the more college courses in geology, physics, and related fields he has, the better. He studies snow, terrain, wind, and weather. He learns the conditions that produce avalanches. He learns to forecast avalanches and to bring them roaring on down the mountainsides to reduce their killing strength. The snow ranger learns to do this by using artillery, by blasting with TNT, and by the difficult and skillful art of skiing avalanches down. The snow ranger, dressed in a green parka which has a bright yellow shoulder patch, means safety forpeople on ski slopes. He pulls the trigger on a 75 mm. Recoilless rifle, skis waist deep in powder testing snow stability, ortalks with the ski area\'s operatoras he goes about his work to protect the public from the hazards of deep snow on steep mountain slopes. The snow rangers are employees of____. 【单选题】
A.the Forest Service.
B.the Resource Bureau.
C.the Tourist Board.
D.the Sports Bureau.
正确答案:A
答案解析:借助备选答案的特点:答案都是专有名词(首字母都大写且名词前有定冠词the),所以可在文章中迅速查找首字母大写的专有名词然后确认答案。很容易在第4段中发珊‘The Forest Service setout to do it,and did with its crops of snow rangers”,该句说“森林服务部和它的护雪场工作人员队伍一起着手做这件事(指控制雪崩)并且做到了”,于是确认答案是A。
8、Meet Your Memory1. Memory is something that cannot be seen, touched orweighed. It is thought to be abstract. It is a setof skills rather than an object. Neither is there a single standard forjudging a good orpoormemory. There are a number of different ways in which a person may have a good memory.2. Memory is generally viewed as consisting of three stages: (1) acquisition refers to learning the material; (2) storage refers to keeping the material in the brain until it is needed; (3) retrieval (提取) refers to getting the material back out when it is needed:3. Memory consists of at least two different processes: short - term memory and long - term memory. Short - term memory has a limited capacity and a rapid forgetting rate. Its capacity can be increased by chunking (组成大块), orgrouping separate bits of information into larger chunks. Long - term memory has an almost unlimited capacity.4. One measure of memory is recall, which requires you to produce information by searching the memory forit. In aided recall, you are given cues (提示) to help you produce the information. In free - recall learning you recall the material in any order. In serial learning you recall it in the orcerit was presented and in paired - associate learning you learn pairs of words so that when the first word is given you can recall the second word. A second measure of memory is recognition, in which you do not have to produce the information from memory, but must be able to identify it when it is presented to you. In a third measure of memory, relearning, the difference between how long it took to learn the material the first time and how long it takes to learn it again indicates how much you remember. Relearning is generally a more sensitive measure of memory than is recognition because relearning shows retention (保持) while recognition does not. Recognition is generally a more sensitive measure than recall.Paragraph 1 ______【单选题】
A.Why do we forget things?
B.How do we measure memory?
C.What are the stages memory consists of?
D.What is the difference between short - term memory and long - term memory?
E.What is memory?
F.Who may have a poormemory?
正确答案:E
答案解析:本题有一定难度,没有明显的主旨句,需要较强归纳能力。通读文章第一段可以发现,第一段主要对记忆力下了定义,围绕定义展开了阐述,回来看选项,E项What is memory?简单概括了第一段,是答案。
9、Medicine Award Kicks off Nobel Prize AnnouncementsTwo scientists who have won praise forresearch into the growth of cancer cells could be candidates forthe Nobel Prize in medicine when the 2008 winners are presented on Monday, kicking off six days of Nobel announcements. Australian-born U. S. citizen Elizabeth Blackburn and American Carol Greider have already won a series of medical honors fortheir enzyme research and experts say they could be among the front-runners fora Nobel. Only seven women have won the medicine prize since the first Nobel Prizes were handed out in 1901. The last female winner was U. S. researcher Linda Buck in 2004, who shared the prize with Richard Axel. Among the pair\'s possible rivals are Frenchman Pierre Chambon and Americans Ronald Evans and Elwood Jensen, who opened up the field of studying proteins called nuclear hormone receptors. As usual, the award committee is giving no hints about who is in the running before presenting its decision in a news conference at Stockholm\'s Karolinska Institute. Alfred Nobel, the Swede who invented dynamite, established the prizes in his will in the categories of medicine, physics, chemistry, literature and peace. The economics prize is technically not a Nobel but a 1968 creation of Sweden\'s central bank. Nobel left few instructions on how to select-winners, but medicine winners are typically awarded fora specific breakthrough rather than a body of research. Hans Jornvall, secretary of the medicine prize committee, said the 10 million kronor(US$1. 3 million) prize encourages groundbreaking research but he did not think winning it was the primary goal forscientists. "Individual researchers probably don\'t look at themselves as potential Nobel Prize winners when they\'re at work," Jornvall told The Associated Press. "They get their kicks from their research and their interest in how life functions. "In 2006, Blackburn, of the University of California, "San Francisco, and Greider, of Johns Hopkins University in Baltimore, shared the Lasker prize forbasic medical research with Jack Szostak of Harvard Medical School. Their work setthe stage forresearch suggesting that cancer cells use telomerase to sustain their uncontrolled growthThe research by Blackburn and Greider helps suggest the role of____. 【单选题】
A.money in medical research.
B.proteins in cancer treatment.
C.hormones in the functioning of life.
D.telomerase in the growth of cancer cells.
正确答案:D
答案解析:短文的最后一句话表明,研究显示癌细胞利用端粒酶来支持其无限增殖,而这几位科学家的工作为这种研究打下了基础。
10、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 forthe 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 forthe most part the children enjoy the fun of dressing up and playing their favorite game of "Trick orTreat". They run down each street knocking on the doors crying loudly "Trick orTreat! Money oreat!", and most people have some sweets ormoney ready to give them. Those that do not can expect maybe to have a tyre flattened, ortheir windows covered in soap. orthe children may just knock on the doorand run away. Some children think of other people on Halloween. They carry boxes forUNICEF (The United Nations International Children\'s Emergency Fund). They ask formoney to help poorchildren all around the world. Of course, every time they help UNICEF, they usually receive a treat forthemselves, 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 forfarmers.
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。
