3、Why Would They Falsely Confess?
Why on earth would an innocent person falsely confess to committing a crime? To most people, it just doesn＇t seem logical. But it is logical, say experts, if you understand what can happen in a police interrogation room.
Under the right conditions, people＇s minds are susceptible to influence, and the pressure put on suspects during police grilling is enormous. "It＇s a little like somebody＇s working on them with a dental drill," says Franklin Zimring, a law professor at the University of California at Berkeley. "The pressure is important to understand, because otherwise it＇s impossible to understand why someone would say he did something he didn＇t do. The answer is: to put an end to an uncomfortable situation that will continue until he does confess."
Developmental psychologist Allison Redlich recently conducted a laboratory study to determine how likely people are to confess to things they didn＇t do. In her experiment, participants were seated at computers and told not to hit the "alt" key, because doing so would crash the systems. The researchers then intentionally crashed the computers and accused the participants of hitting the "alt" key to see if they would sign a statement falsely taking responsibility.
Redlich＇s findings clearly demonstrate how easy it can be to get people to falsely confess: 59 percent of the young adults in the experiment immediately confessed. ______ Of the 15-to 16-year-olds, 72 percent signed confessions, as did 78 percent of the 12-to 13-year-olds.
"There＇s no question that young people are more at risk," says Saul Kassin, a psychology professor at Williams College, who has done similar studies with similar results, "But adults are highly vulnerable too."
Both Kassin and Redlich note that the entire "interrogation" in their experiments consisted of a simple accusation-not hours of aggressive questioning-and still, most participants falsely confessed.
Because of the stress of a police interrogation, they conclude, suspects can become convinced that falsely confessing is the easiest way out of a bad situation. "In some ways," says Kassin, "false confession becomes a rational decision."

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 ______. 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.

5、Citizen Scientists
Understanding how nature responds to climate change will require monitoring key life cycle event-flowering, the appearance of leaves, the first frog calls of the spring all around the world.
But ecologists can＇t be everywhere so they＇re turning to non-scientists, sometimes called citizen scientists, for help.
Climate scientists are not present everywhere. Because there are so many places in the world and not enough scientists to observe all of them, they＇re asking for your help in observing signs of climate change across the world. The citizen scientist movement encourages ordinary people too observe a very specific research interest-birds, trees, flowers budding, etc. and send their observations to a giant database to be observed by professional scientists. This helps a small number of scientists track a large amount of data that they would never be able to gather on their own. Much like citizen journalists helping large publications cover a hyper-local beat, citizen scientists are ready for the conditions where they live. All that＇s needed to become one is a few minutes each day or each week to gather data and send it in.
A group of scientists and educators launched an organization last year called the National Phenology Network. "Phenology" is what scientists call the study of the timing of events in nature.
One of the group＇s first efforts relies on scientists and non-scientists alike to collect data about plant flowering and leafing every year. The program, called Project BudBurst, collects life cycle data on a variety of common plants from across the United States. People participating in the project which is open to everyone record their observations on the Project BudBurst website.
"People don＇t have to be plant experts, they just have to look around and see what＇s in their neighborhood," says Jennifer Schwartz, an education consultant with the project. "As we collect this data, we＇ll be able to make an estimate of how plants and communities of plants and animals will respond as the climate changes. "
What is NOT true of Project BudBurst?
【单选题】

A.Only experts can participate in it.

B.Everybody can participate in it.

C.It collects life cycle data on a variety of common plants.

D.It has its own website.

正确答案:A

答案解析:文章全文都在说普通人参与科学研究的项目，因此只有选项A不符合。其他选项都能在文中找出。

6、Cloning: Future Perfect?
1 A clone is an exact copy of a plant or animal produced from any one cell. Since Scottish scientists reported that they had managed to clone a sheep named Dolly in 1997, research into cloning has grown rapidly. In May 1998, scientists in Massachusetts managed to create two identical calves using cloning technology. A mouse has also been cloned successfully. But the debate over cloning humans really started when Chicago physicist Richard Seed made a surprising announcement: "We will have managed to clone a human being within the next two years," he told the world.
2 Seed＇s announcement provoked a lot of media attention, most of it negative. In Europe, nineteen nations have already signed an agreement banning human cloning and in the US the President announced: "We will be introducing a law to ban human cloning and many states in the US will have passed anti-cloning laws by the end of the year".
3 Many researchers are not so negative about cloning. They are worried that laws banning human cloning will threaten important research. In March, The New England Journal of Medicine called any plan to ban research on cloning humans seriously mistaken. Many researchers also believe that in spite of attempts to ban it, human cloning will have become routine by 2010 because it is impossible to stop the progress of science.
4 Is there reason to fear that cloning will lead to a nightmare world? The public has been bombarded (轰炸) with newspaper articles, television shows and films, as well as cartoons. Such information is often misleading, and makes people wonder what on earth the scientists will be doing next.
5 Within the next five to ten years scientists will probably have found a way of cloning humans. It could be that pretty soon we will be able to choose the person that we want our child to look like. But how would it feel to be a clone among hundreds, the anti-cloners ask Pretty cool, answer the pro-cloners (赞成克隆的人).
Within ten years scientists will probably have____.
【单选题】

A.the nucleus of a cell

B.cloned human beings

C.a human being in two years

D.a law to ban human cloning

E.a report on human cloning

F.heavy media coverage

正确答案:B

答案解析:文章最后一段提到未来5到10年内人们可能会找到克隆人的办法，即会有克隆人出现，故选B。

7、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. ______
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. They could also be leaching into tap water pumped from rocks beneath fertilized fields.
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.
【单选题】

A.They do not easily degrade or dissolve 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。

8、The Book of Life
So far, scientists have named about 1.6 million living species, and that＇s a just a fraction of that probably exists on Earth. With so many plants, animals and other creatures coveting the planet, it can be tough to figure out what type of spider is moving up your leg or what kind of bird is flying by.
A soon - to - be - started Web site might help. An international team of researchers has announced the creation of Web - based Encyclopedia of life( EOL). The project aims to catalog every species on Earth in a single, easy - to - use reference guide.
To get the encyclopedia started, the creators will use information from scientific databases that already exist. And eventually, in special sections of the site, nonscientist with specialized knowledge will get to join in. Bird - watchers, for example, will be able to input which bird they＇ve seen and where. The technology for this kind of tool has only become available.
As the EOL develops, you might find it useful for school projects. The site will feature special pages for kids who are studying ecosystems (生态系统) in their neighborhoods. To make sure the encyclopedia is accurate, scientists will review much of the information added to it. People who visit the site will be able to choose to leave out pages that haven＇t been reviewed.
Another convenient feature of the EOL is that you＇ll be able to pick the level of detail you want to see to match your interest, age and knowledge. If you wanted to learn about bears for a science class report, for example, you could use the "novice" setting to get basic information about the animals. On the "expert" setting, on the other hand, you could get much more detailed information about the history, literature and exploration of bears.
It now takes years for scientist to collect all the data they need to describe and analyze species. The creator of the Encyclopedia of Life hope that their new tool will speed up that process.
"Spider" and "bird" mentioned in Paragraph 1 are examples to illustrate ______.【单选题】

A.there are numerous living species on Earth

B.animals are people＇s friends

C.it is easy to see spiders and birds

D.here are many types of spiders and birds

正确答案:A

答案解析:本题有一定难度，带着题干信息词回文章定位，答案依据主要在文章第一段：So far, scientists have named about l.6 million living species, ...it can be tough to figure out what type of spider is moving up your leg or what kind of bird is flying by.谈到了地球物种数量巨大，回来看选项，A项和原文句意相近，是答案。

B.Scientists will review every piece of the information added to EOL.

C.Scientists have cataloged only a small part of the living species.

D.People with different interests and knowledge will in a way find EOL useful.

正确答案:B

答案解析:本题有一定难度，需要通读全文，寻找答案依据。答案依据主要在文章第四段倒数第二句：To make sure the encyclopedia is accurate．scientists will review much of the information added to it．显然，科学家是review much of the information，而不是every piece of the information，选项B项和原文句意不符，是答案。

10、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 _____ kinds of materials, could one day contain a color - changing material. It will turn red before a structure collapses or falls apart.
The secret behind the color - changing material is a particular type of molecule (分子). A molecule is a group of atoms (原子) held together by chemical bonds. Molecules come in 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 - changing molecule called a mechanophore (机械响应性聚合物) is about to break, it produces 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 - changing polymers in their lab. The test results proved encouraging.
There is a way to get rid of the red color light. When a bright light is shone on the mechanophore, the broken bond is fixed and the red color disappears. Thus "self - healing" may be a problem for engineers. They need to use the color - changer in big construction projects that will be outside, under sunlight. And sunlight will make the mechanophore＇s warning system useless.
Sottos and her fellow scientists still have a lot of work to do before the color - changing molecules can be used outside the lab.
