听力原文： In a way, all of us are on a spaceship, the planet Earth. We move around the sun at 18 miles per second and never stop. On our spaceship we have five billion people and limited supply of air, water, and land. These supplies have to be used careful because we can't buy new air, water, or land from anywhere else.
The environment on our planet is a closed system: nothing new is ever added. Nature recycles its resources. Water, for example, evaporates and rises as visible drops to form. clouds. This same water returns to the Earth as rain or snow. The rain that falls today is actually the same water that fell on the land 70 million years ago.
Today, the Earth is in trouble. Factories pour dirty water into our rivers. Many fish die and the water becomes unhealthy for people to drink. Cars and factories put poisons into the air and cause plants, animals and people to get sick. People throw bottles and paper out of their car windows, and the roadside becomes covered with al sorts of wastes. Over the years, people have changed the environment, and we have pollution.
To continue to survive, we must learn how to use the Earth's resources wisely. We have to change our habits and stop dumping such enormous amounts of industrial waste into the water and air. We must cooperate with nature and learn better ways to use, not abuse, our environment.
(33)
A．Because both have a limited supply of air, water, and other resources.
B．Because the Earth moves around the sun as fast as a spaceship.
C．Because we can travel to outer space.
D．Because the Earth never stops moving.

is the founder of Auburn University's institute for Biological Detection Systems, the main task of which is to chase the ultimate in detection devices-an artificial nose.
For now, the subject of their research is little more than a stack of gleaming chips tucked away in a laboratory drawer. But soon, such a tool could be hanging form. the belts of police, arson (纵火) investigators and fund-safety inspectors. The technology that they are working on would suggest quite reasonable that, within three to five years, we'll have some workable sensors ready to use. Such devices might find wide use in places that attractterrorists. Police could detect drugs, bodies and bombs hidden in cars, while food inspectors could easily test food and water for contamination.
The implications for revolutionary advances in public safety and the food industry are astonishing. But so, too,are the possibilities for abuse: Such machines could determine whether a woman is ovulating (排卵), without a physical exam or even her knowledge.
One of the traditional protectors of American liberty is that it has been impossible to search everyone. That's getting not to be the case.
Artificial biosensors created at Auburn work totally differently from anything ever seen before. Aromascan, for example, is a desktop machine based on a bank of chips sensitive to specific chemicals that evaporate into the air. As air is sucked into the machine, chemicals pass over the sensor surfaces and produce changes in the electrical current flowing through them. Those current changes are logged into a computer that sorts out odors based on their electrical signatures.
Myers says they expect to lead a single fingernail-size chip with thousands of odor receptors(感受器), enough to create a sensor that's nearly as sensitive as a dog's nose.
Which of the following is within the capacity of the artificial nose being developed？
A．Performing physical examinations.
B．Locating places which attract terrorists.
C．Detecting drugs and water contamination.
D．Monitoring food processing.

Animal welfare groups are apparently most concerned with high school students experimenting with animals in extracurricular projects. Barbara Orlans, President of the Scientists' Center for Animal Welfare, said that students have been performing surgery at random, testing known poisonous substances, and running other pathology (病理学) experiments on animals without even knowing normal physiology (生理学).
At one science fair, a student cut off the leg and tail of a lizard (蜥蜴) to demonstrate that only the tail can regenerate, she said. In another case, a student bound sparrows, starved them and observed their behavior.
"The amount of abuse had been quite horrifying," Orlans said.
Administrators of major science fairs are short-tempered over the teachers' policy change and the impression it has created. "The teachers were sold a bill of goods by Barbara Orlans," said Thurman Grafton, who heads the rules committee for the International Science and Engineering Fair. "Backyard tabletop surgery is just nonsense. The new policies throw cold water on students inquisitiveness," he said. Grafton said he wouldn't deny that there hasn't been animal abuse among projects at the international fair, but he added that judges reject contestants who have unnecessarily injured animals. The judges have a hard time monitoring local and regional fairs that may or may not choose to comply with the international fair's rules that stress proper care of animals, Grafton said.
He said that several years ago, the Westinghouse Science Talent Search banned harmful experiments to animals when sponsors threatened to cancel their support after animal welfare groups lobbied for change.
The teachers adopted the new policies also to fend off proposed legislation — in states including Missouri and New York — that would restrict or prohibit experiments on animals.
Officials of the two teachers' organizations say that they don't know how many animals have been abused in the classroom. On the one hand, many biology teachers are not trained in the proper care of animals, said Wayne Moyer, executive director of the biology teachers' association. On the other hand, the use of animals in experiments has dropped in recent years because of school budget cuts. The association may set up seminars to teach better animal care to its members.
What is the passage mainly about？
A．Science teachers banning testing harmful to animals.
B．Teachers' policy change in experiment on animals.
C．The new policies of banning harmful experiments to animals.
D．The importance of prohibiting harmful experiments on animals.

听力原文： The first step to stop drug abuse is knowing why people start to use drugs. The reasons people abuse drugs are as different as people are from one to another. But there seems to be one common thread: people seem to take drugs to change the way they feel. They want to feel better or to feel happy or to feel nothing. Sometimes, they want to forget or to remember. People often feel better about the roseleaf when they are under the influence of drugs. But the effects don't last long. Drugs don't solve problems. They just postpone them. No matter how far drugs may take you, it's always around trip. After a while, people who miss drugs may feel worse about themselves, and then they may use more drugs. If someone you know is using or abusing drugs, you can help. The most important part you can play is to be there. You can let your friends know that you care. You can listen and try to solve the problem behind your friend's need to use drugs. Two people together can often solve a problem that seems too big for one person alone. Studies of heavy abusers in the United States show that they felt unloved and unwanted. They didn't have close friends to talk to. When you or your friends take the time to care for each other, you're all helping to stop drugs abuse. After all, what is a friend for？
(23)
A．To show off their wealth.
B．To feel good.
C．To regain their memory.
D．To be different from others.
