1、CancerCancer is a group of 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 or tumor. 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 or order.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, or exposure to carcinogens (致癌物) in the workplace or in the environment. Some gene alterations are inherited.Cancer treatment can include surgery, radiation therapy, chemotherapy （化疗), hormone therapy, and biological therapy. The doctor may use one method or a 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 for cancer 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 for pain. Most pain occurs when the cancer grows and presses against bones, organs, or nerves. Pain may also be a side effect of treatment. However, pain can generally be relieved or reduced with prescription medicines or over-the-counter drugs recommended by the doctor.Gene alterations may be caused by____.【单选题】

A.prescription medicines

B.control or order

C.tolerance for pain

D.various factors

E.normal genes

F.different genes side effects

正确答案:D

答案解析:根据题干线索词Gene alterations定位原文至第二段第二句“Certain lifestyle and environmental factors can change some normal genes into genes that allow the growth of cancer”，题干中的alterations与句中的change虽然词性不同，但意思相同。题干将该句由主动态变为被动态，由此推断，句中画线部分即为题干所需添加成分。而D选项various factors是对该部分的同义改写，故为正确答案。

2、Cars Are Good for the Environment，HonestBritain\'s motor industry is planning a major publicity campaign to counter what it sees as an official anti-car bias and to improve the environmental image of the cars, according to documents leaked to the pressure group, Friends of the Earth (FOE). The five-year campaign could cost up to ￡12 million.The internal document which was produced last month by the Society of Motor Manufacturers and Traders, says that the "ultimate objective of the campaign must be to protect the long-term commercial freedom of the motor industry and the lifestyle freedom of car users". The campaign will highlight the motor industry\'s efforts to reduce emissions of carbon dioxide. European car manufacturers have already agreed with the European Com mission to reduce CO2 emissions from new cars by 25 percent to target of 140 grams per kilometer by 2008. However, the document also reveals that the industry is someway from meeting the target. For example, last year\'s new cars exceed an average of 192 grams per kilometre—some 37 percent above the target.To help control these emissions, the government has proposed replacing the flat rate annual tax on cars with a tax related to engine size so that owners of large gas-guzzler would pay more than owners of small cars. But the motor industry opposes taxes on persons owning cars preferring taxes on use.Richard Barnet, the society\'s media manager, says: "We will work with the government to practice a practical system. " ____【单选题】

A.The campaign will highlight the motor industry\'s efforts to reduce emissions of carbon dioxide.

B.But the motor industry opposes taxes on persons owning cars preferring taxes on use.

C.The five-year campaign could cost up to ￡16 million.

D.The reason why cars are good for the environment is obvious.

E.But Ian Willmore of FOE says the industry “may pose as partners of the government, but its real intention is to frustrate serious attempts to reduce traffic levels”.

F.For example, last year\'s new cars exceed an average of 192 grams per kilometre—some 41 percent above the target.

正确答案:E

答案解析:前一句是Richard Barnet对政府和汽车行业在此活动执行上的看法，而E选项则对他的想法进行了相应的改动，并起到了进一步升华的作用。因此，选择E。

3、MemoriesMost episodes of absent-mindedness forgetting where you left something or wondering why you just entered a room are caused by a simple lack of attention, says Schacter. "You are supposed to remember something, but you haven\'t encoded it deeply."Encoding, Schacter says, is a special way of paying attention to an event that has a major impact on recalling it later. Failure to encode properly can create annoying situations. If you put your mobile phone in a pocket, for example, and don\'t pay attention to what you did because you are involved in a conversation, you will probably forget that the phone is in the jacket now hanging in your wardrobe. "Your memory itself isn\'t failing you," says Schacter. " Rather, you didn\'t give your memory system the information it needed. "____. "A man who can recite sports statistics from 30 years ago," says Zelinski, "may not remember to drop a letter in the mailbox. " Women have slightly better memories than men, possibly because they pay more attention to their environment, and memory relies on just that.Visual cues can help prevent absent-mindedness, says Sclnacter." But be sure the cue is clear and available.,"he cautions. If you want to remember to take a medication with lunch, put the pill bottle on the kitchen table don\'t leave it in the medicine chest and write yourself a note that you keep in a pocket.Another common episode of absent-mindedness: walking into a room and wondering why you are there. Most likely, you were thinking about something else. "Everyone does this from time to time," says Zelinski. The best thing to do is to return to where you were before entering the room, and you will likely remember.【单选题】

4、BaseballThere are people in Italy who can\'t stand soccer. Not all Canadians love hockey. A similar situation exists in America, where there are those individuals you may be one of them who yawn or even frown when somebody mentions baseball. Baseball to them means boring hours watching grown men in funny tight outfits standing around in a field staring away while very little of anything happens. They tell you it\'s a game better suited to the 19th century, slow, quiet and gentlemanly. These are the same people you may be one of them who love football because there\'s the sport that glorifies "the hit".By contrast, baseball seems abstract, cool, silent and still. On TV the game is fractured into a dozen perspectives, replays and close ups. The geometry of the game, however, is essential to understanding it. You will contemplate the game from one point as a painter does his subject; you may, of course, project yourself into the game. It is in this projection that the game affords so much space and time for involvement. The TV won\'t do it for you.Take, for example, the third baseman. You sit behind the third base dugout and you watch him watching home plate. His legs are apart, knees flexed. His arms hang loose. He does a lot of this. The skeptic still cannot think of any other sports so still, so passive. But watch what happens every time the pitcher throws: the third baseman goes up on his toes, flexes his arms or bring the glove to a point in front of him, takes a step right or left, backward or forward, perhaps he glances across the field to check his first baseman\'s position. Suppose the pitch is a ball. "Nothing happened," you say. "I could have had my eyes closed".The skeptic and the innocent must play the game. And this involvement in the stands is no more intellectual than listening to music is. Watch the third baseman. Smooth the dirt in front of you with one foot; smooth the pocket in your glove; watch the eyes of the batter, the speed of the bat, the sound of horsehide on wood if football is a symphony of movement and theatre, baseball is chamber music, a spacious interlocking of notes, chores and responses.The author admits that ____.【单选题】

A.baseball is too peaceful for the young

B.baseball may seem boring when watched on TV

C.football is more attracting than baseball

D.baseball is more interesting than football

正确答案:B

答案解析:第三段指出，在电视上垒球运动被切换成不同角度的画面，而且不断地使用重放、特写等电视制作技术，这破坏了该运动的整体运动感，使观众无法将自己投入(project)到运动中去，以体会到这种寓动于静的运动之美。电视做不到这一点(The TV won\'t do it for you)，电视上的垒球比赛看上去(seems)孤孤单单、冷冷清清、沉沉静静、慢慢腾腾。C、D不对，作者仅指出了不同运动有不同运动的特征，并未说哪种运动优于哪种。参阅文章最后一句。

5、Ten years after the event, her death still remains a puzzle.【单选题】

A.mist

B.fog

C.secret

D.mystery

正确答案:D

答案解析:事情发生10年后，她的死因仍是个谜。本题难度较大，干扰项干扰很强，主要是C项。puzzle指“困惑，不解之谜”，和mystery“神秘的”是近义词，都是指人们还暂时没有揭开谜团。C项secret指“秘密”，是指一部分人已知道真相，所以和puzzle，mystery是有区别的，最佳答案是D。
