1、The motorcarSome pessimistic experts feel that the automobile is bound to fall into disuse. They see a day in the not-too-distant future when all autos will be abandoned ａｎｄ　allowed to rust. Other authorities, however, think the auto is here to stay. They hold that the car will remain a leading means of urban travel in the foreseeable future.The motorcar will undoubtedly. change significantly over the next 30 years. It should become smaller, safer, ａｎｄ　more economical, ａｎｄ　should not be powered by the gasoline engine. The car of the future should be far more pollution-free than present types.Regardless of its power source, the auto in the future will still be the main problem in urban traffic congestion. One proposed solution to this problem is the automated highway system.When the auto enters the highway system, a retractable (可伸缩的) arm will ｄｒｅｐfrom the auto ａｎｄ　make contact with a rail, which is similar to those powering subway trains electrically. Once attached to the rail, the car will become electrically powered from the system, ａｎｄ　control of the vehicle will pass to a central computer. The computer will then monitｏｒall of the car\'s movements.The driver will use a telephone to dial instructions about his destination into the system. The computer will calculate the best route, ａｎｄ　reserve space fｏｒthe car all the way to the correct exit from the highway. The driver will then be free to relax ａｎｄ　wait fｏｒthe buzzer (蜂鸣器) that will warn him of his coming exit. It is estimated that an automated highway will be able to handle 10,000 vehicles per hour, compared with the 1,500 to 2,000 vehicles that can be carried by a present-day highway.What is the author\'s main concern?【单选题】

A.How to render automobiles pollution-free.

B.How to make smaller ａｎｄ　safer automobiles.

C.How to solve the problem of traffic jams.

D.How to develop an automated subway system.

正确答案:C

答案解析:从文章第三段the auto in the future will still be the main problem in urban traffic congestion来看，作者主要关心的还是如何解决交通堵塞的问题，即C。

2、In the process, the light energy converts to heat energy.【单选题】

A.reduces

B.changes

C.leaves

D.drops

正确答案:B

答案解析:在这个过程中，光能转化成热能。converts指“转变”，通常与to或者into搭配，和changes“变化”是近义词，其他三项都是常用词，和答案意义差异较大，干扰性不强。

3、CancerCancer is aｇｒｏｕｐof many related diseases that begin in cells, the body\'s basic building blocks. The body is made up of many types of cells. Normally cells grow ａｎｄ　divide to produce more cells as they are needed to keep the body healthy. Sometimes, this orderly process goes wrong. New cells form when the body does not need them, ａｎｄ　old cells do not die when they should. The extra cells form a mass of tissue called a growth ｏｒtumor. Benign (良性的) tumors are not cancer. They can often be removed and, in most cases, they do not come back. Malignant (恶性的) tumors are cancer. Cells in malignant tumors are abnormal ａｎｄ　divide without control ｏｒorder.Scientists have learned that cancer is caused by changes in genes that normally control the growth ａｎｄ　death of cells. Certain lifestyle ａｎｄ　environmental factors can change some normal genes into genes that allow the growth of cancer. Many gene changes that lead to cancer are the result of tobacco use, diet, exposure to ultraviolet radiation from the sun, ｏｒexposure to carcinogens (致癌物) in the workplace ｏｒin the environment. Some gene alterations are inherited.Cancer treatment can include surgery, radiation therapy, chemotherapy （化疗), hormone therapy, ａｎｄ　biological therapy. The doctｏｒmay use one method ｏｒa combination of methods, depending on the type ａｎｄ　location of the cancer, whether the disease has spread, the patient\'s age ａｎｄ　general health, ａｎｄ　other factors. Because treatment fｏｒcancer can also damage healthy cells ａｎｄ　tissues, it often causes side effects. Patients ａｎｄ　doctors generally discuss the treatment options, weighing the likely benefits of killing cancer cells ａｎｄ　the risks of possible side effects.Having cancer does not always mean having pain. Whether a patient has pain may depend on the type of cancer, the extent of the disease, ａｎｄ　the patient\'s tolerance fｏｒpain. Most pain occurs when the cancer grows ａｎｄ　presses against bones, organs, ｏｒnerves. Pain may also be a side effect of treatment. However, pain can generally be relieved ｏｒreduced with prescription medicines ｏｒover-the-counter drugs recommended by the doctor.Paragraph 2____.【单选题】

A.Does cancer always cause pain

B.Can cancer be prevented

C.What is cancer

D.How common is cancer

E.What causes cancer

F.How is cancer treated

正确答案:E

答案解析:第二段主题句为第一句，其意思是：科学家研究证明，癌症是由正常情况下控制细胞生长和死亡的基因发生突变引起的。由此推断，该段回答了E选项“What causes cancer?”所提问题，故E为正确答案。

正确答案:A

答案解析:focus on和concentrate on意思相同：集中（注意力等）；complete:完成、填写（表格）；remind:提醒、使想起；pay for：为某物付款。

5、Smoking Can Increase Depressive Symptoms in TeensWhile some teenagers may puff on cigarettes to "self-medicate" against the blues, scientists at the University of Toronto ａｎｄ　the University of Montreal have found that smoking may actually increasedepressive symptoms in some teens."This observational study is one of the few to examine the perceived emotional benefits of smoking among teens," says lead researcher Michael Chaiton, a research associate at the Ontario Tobacco Research Unit of the University of Toronto." Although cigarettes may appear to have self-medicating effects ｏｒto improve mood, in the long term we found that teens who started to smoke reported higher depressive symptoms. "As part of the study, some 662 high school teenagers completed up to 20 questionnaires about their use of cigarettes to affect mood. Secondary schools were selected to provide a mix of French ａｎｄ　English participants, urban ａｎｄ　rural schools, ａｎｄ　schools located in high, moderate ａｎｄ　low socioeconomic neighborhoods. Participants were divided into three groups: never smokers; smokers who did not use cigarettes to self-medicate, improve mood ｏｒphysical state; smokers who used cigarettes to self-medicate. Depressive symptoms were measured using a scale that asked how felt too fired to do things: had ____ going to sleep ｏｒstaying asleep; felt unhappy, sad, ｏｒdepressed; felt hopeless about the future; felt vexed, antsy ｏｒtense; ａｎｄ　worried too much about things."Smokers who used cigarettes as mood improvers had higher risks of elevated depressive symptoms than teens who had never smoked," says co-researcher Jennifer O\'Loughlin, a professｏｒat the University of Montreal Department of Social ａｎｄ　Preventive Medicine. "Our study found that teen smokers who reported emotional benefits from smoking are at higher risk of developing depressive symptoms."The association between depression ａｎｄ　smoking exists principally among teens that use cigarettes to feel better. "It\'s important to emphasize that depressive symptom scores were higher among teenagers who reported emotional benefits from smoking after they began to smoke," says Dr. Chaiton.【单选题】
