1、How to Interview People
Interviewing (采访) is one of those skills that you can only get better at. You will never again feel so ill at ease when you try it for the first time, and probably you'll never feel entirely comfortable trying to get from another person answers that he or she may be too shy to reveal. But at least half of the skill is mechanical. The rest is instinct, which can all be learned with experience.
The basic tools for an interview are paper and two or three well-sharpened pencils. But keep your notebook or paper out of sight until you need it. There's nothing less likely to relax a person than the arrival of someone with a note-taking pad. Both of you need time to get to know each other. Take a while just to chat, judging what sort of person you're dealing with, getting him or her to trust you.
Never go into an interview without doing whatever homework you can. If you are interviewing a town official, know his voting record. If it's an actor, know what plays he has been in. You will not be liked if you inquire about facts that you could have learned in advance.
Many beginning interviewers are afraid that they are forcing the other person to answer questions and have no right to inquire about his personal secrets. ______ Unless the person really hates being interviewed, he is delighted that somebody wants to interview him. Most men and women lead lives that are uninteresting, and they grasp any chance to talk to an outsider who seems eager to listen.
This doesn't necessarily mean that it will go well. In general you will be talking to people who have never been interviewed before, and they will get used to the process awkwardly, perhaps not giving you anything that you can use. Come back another day; it will go better. You will both even begin to enjoy it-proof that you aren't forcing your victim to do something he doesn't really want to.
【单选题】

A.Come back another day; it will go better.

B.But at least half of the skill is mechanical.

C.As one philosopher interviewed in the film notes, they lack irony.

D.You will not be liked if you inquire about facts that you could have learned in advance.

E.This fear is almost 103 percent unnecessary.

F.Both of you need time to get to know each other.

正确答案:E

答案解析:抓住关键词进行同义替换，关键词就是afraid，选项中this fear就是对这种担心的补充，这种担心是完全没有必要的，除非被采访者确实是讨厌别人问自己的隐私。

2、Medicine Award Kicks off Nobel Prize Announcements
Two scientists who have won praise for research into the growth of cancer cells could be candidates for the 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 for their enzyme research and experts say they could be among the front-runners for a 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 for a 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 for scientists.
"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 for basic medical research with Jack Szostak of Harvard Medical School. Their work set the stage for research suggesting that cancer cells use telomerase to sustain their uncontrolled growth
The 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。

3、Seeing Red Means Danger Ahead
The color red often means danger and by paying attention, accidents can be prevented. In the future, the color red also may help prevent danger at construction sites. Thanks to new work by engineers, bridge supports or other kinds of materials could one day contain a color switching material. It will turn red before a structure collapses or falls apart.
The secret behind the color switching material is a particular type of molecule. A molecule is a group of atoms held together by chemical bonds. Molecules come ______ all shapes and sizes, and make up everything. You can see, touch or feel. How a molecule behaves depends on what kinds of atoms it contains, and how they're held together.
When a polymer (聚合物) containing a color switching molecule called a mechanophore (机械响应性聚合物) which is about to break, it produce a color. When a polymer with mechanophore molecules becomes "injured" or weak, one of the mechanophore bonds breaks and the material turns red. "It's a really simple detection method. "says Nancy Sottos, one of the scientists who worked on the project. Sottos and her team tested the color switching polymers in their lab. The test results proved encouraging.
There is a way to get rid of the color light when a bright light is shone on the mechanophore.
The broken bond is fixed and the red color disappears. This "self-healing" may be a problem for engineers. They need to use the color changer in big construction projects that will be outside in sunlight. And sunlight will make the mechanophore's warming system useless. Sottos and her fellow scientists still have a lot of work to do before the color switching molecules can be used outside the lab.
【单选题】

A.for

B.in

C.from

D.at

正确答案:D

答案解析:come at shapes and sizes，习惯用法。

4、Radiocarbon Dating
Nowadays scientists can answer many questions about the past through a technique called radiocarbon (放射性碳), or carbon - 14 dating. One key to understanding how and why something happened is to discover when it happened.
Radiocarbon dating was developed in the late 1940s by physicist Willard F. Libby at the University of Chicago. An atom of ordinary carbon, called carbon -12, has six protons (质子) and six neutrons (中子) in its nucleus (原子核). Carbon - 14, or C - 14, is a radioactive, unstable form of carbon that has two extra neutrons. It returns to a more stable form of carbon through a process called decay (衰减). This process involves the loss of the extra neutrons and energy from the nucleus.
In Libby's radiocarbon dating technique, the weak radioactive emissions(放射)from this decay process are counted by instruments such as a radiation detector and counter. The decay rate is used to determine the proportion of C -14 atoms in the sample being dated.
Carbon - 14 is produced in the Earth's atmosphere when nitrogen(氮) - 14, or N - 14, interacts with cosmic rays (宇宙射线). Scientists believe since the Earth was formed, the amount of nitrogen in the atmosphere has remained constant. Consequently, C -14 formation is thought to occur at a constant rate. Now the ratio of C -14 to other carbon atoms in the atmosphere is known. Most scientists agree that this ratio is useful for dating items back to at least 50,000 years.
All life on Earth is made of organic molecules (分子) that contain carbon atoms coming from the atmosphere. So all living things have about the same ratio of C -14 atoms to other carbon atoms in their tissues (组织). Once an organism (有机体) dies it stops taking in carbon in any form, and the C -14 already present begins to decay. Over time the amount of C - 14 in the material decreases and the ratio of C - 14 to other carbon atoms goes down. In terms of radiocarbon dating, the fewer C -14 atoms in a sample, the older that sample is.
Radiocarbon is reliable in dating an object back to at least 50,000 years.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:本题难度不大，答案依据比较明显，主要答案依据在文章第四段最后一句：Most scientists agree that this ratio is useful for dating items back to at least 50,000 years谈到科学家相信，这样的比率对于测定5万多年前的物体有用，题干是其近义解释，所以正确，答案是A。

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.
Scientists have been keeping records of lake temperatures for over 30 years.【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，在文章第二段第二句：Between 1985 and 2009，satellites recorded the nighttime temperatures of the surfaces of 1671 akes.很明显，是24年，而不是30多年，题干和原文句意不符，答案是B。

8、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。

10、Dung to Death
Fields 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 Union and the US each year. More than half are given to farm-animals to prevent disease and promote growth. 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.
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 for Environmental 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 for spreading resistance, he said. The drugs contaminate the crops, which are then eaten. ______
Mueller is particularly concerned about a group of antibiotics called sulphonamides. They do not easily degrade or dissolve 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.
