Mosquitoes(蚊子) ruin countless American picnics every year, but around the world, this bloodsucking beast isn’t just annoying--it causes a health problem. More than a million people die from the spread of mosquito-borne diseases like malaria and yellow fever each year. Attempts to control populations via insecticides like DDT have had ruinous side effects for nature and human health. Neurobiologist Leslie B. Vosshall has a different solution for stopping the insects and the spread of disease. “I believe the key to controlling mosquito behavior is to understand better how they sense us,” she says.
At their Rockefeller University lab, Vosshall and her colleagues are studying the chemical sensory processes by which mosquitoes choose hosts. How do they sense heat, humidity, carbon dioxide, and body odor(氣味)? What makes some people more attractive to a mosquito than others? It takes blood and sweat to find out. To study how mosquitoes assess body odor, Vosshall and her teammates might wear stockings on their arms and keep from showering for 24 hours to create sample smells, Then comes the hard part. They insert their arms into the insects’ hidden home to study how mosquitoes land, bite, and feed and then they document how this changes. This can mean getting anywhere from one bite to 400, depending on the experiment. Studying male mosquitoes is more pleasant. Since they don’t feed on blood, the lab tests their sense of smell using honey.
Vosshall and her team have also begun to study how genetics contribute to mosquitoes’ choice of a host. She’s even created a breed that is unable to sense carbon dioxide, an important trigger for the insects. “By using genetics to make mutant(變異的) mosquitoes, we can document exactly how and why mosquitoes hunt humans,” Vosshall says.
Once Vosshall figures out what makes mosquitoes flock to us, she can get to work on making them leave us alone. Many of her lab’s proposed solutions sound simple enough, including bracelets(手鐲) that carry long-lasting repellants(驅(qū)蟲(chóng)劑) or traps that can reduce populations, but the breakthroughs, when they come, may save millions of lives in the developing world—and a lot of itching everywhere else.
1.Vosshall and her colleagues are mainly studying mosquitoes’ ______.
A. appearance B. size
C. behavior D. change
2.By saying the underlined part “Then comes the hard part”, the author probably means that______.
A. the insects smell terrible
B. the experiment will last long
C. The researchers will probably suffer
D. the researchers have to study lots of documents.
3.Why is it less challenging to study male mosquitoes?
A. They are not bloodsuckers.
B. They are afraid of stockings.
C. They have a poor sense of smell.
D. They are protective of their hosts.
4.It can be inferred from the last paragraph that Vosshall’s research______.
A. looks very promising
B. has saved millions of lives
C. is facing great difficulties
D. is quite simple to carry out.

The Diet Zone: A Dangerous Place
Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically(身體上).
Diet products significantly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale(秤)instead. All we have to do is to swallow or recognize the word “diet” in food labels.
On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don’t have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.
The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients(營(yíng)養(yǎng)成分). Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemical that go into diet products are potentially dangerous.
Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological harm that comes from using them.
1.From Paragraph 1, we learn that ________.
A. diet products fail to bring out people’s potential
B. people are fed up with diet products
C. people have difficulty in choosing diet products
D. diet products are misleading people
2.One psychological effect of diet products is that people tend to _____.
A. hesitate before they enjoy diet foods
B. pay attention to their own eating habits
C. watch their weight rather than their diet
D. try out a variety of diet foods
3.In Paragraph 3, “gain comes without pain” probably means ______.
A. losing weight is effortless
B. diet products bring no pain
C. it costs a lot to lose weight
D. diet products are free from calories
4.Diet products indirectly harm people physically because such products ______.
A. lack basic nutrients B. are over-consumed
C. are short of chemicals D. provide too much energy

Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experience? Strangely enough, the answer to these questions is yes. To some extent our intelligence is given to us at birth, and no amount of special education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of person’s intelligence are fixed at birth, but whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.
It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be intelligence. Thus if we take two unrelated people at random from population, it is likely that their degree of intelligence will be completely different. If on the other hand we take two identical twins, they will very probably be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.
Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all are likely to have similar degrees of intelligence.
1.Which of these sentences best describes the writer’s point in Paragraph 1?
A. To some extent, intelligence is given at birth.
B. Intelligence is developed by the environment.
C. Some people are born clever and others born stupid.
D. Intelligence is fixed at birth, but is developed by the environment.
2.It is suggested in this passage that ________ .
A. unrelated people are not likely to have different intelligence
B. close relation usually have similar intelligence
C. the closer the blood relationship between people, the more different they are likely to be in intelligence
D. people who live in close contact with each other are not likely to have similar degrees of intelligence
3.The phrase “at random” (Line 3, Para.2) means ________ .
A. purposely B. regularly
C. independently D. aimlessly
4.The best title for this article would be ________ .
A. What Does Intelligence Mean?
B. We are Born with Intelligence
C. On Intelligence
D. Environment Plays a Part in Developing Intelligence
