1、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 3____.【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:F

答案解析:第三段没有主题句，但浏览该段会发现其中的高频词treatment，由此推断，该段讲述了癌症的治疗方法。段中详细介绍了癌症的治疗方法，如手术切除、放射治疗、化疗、生物学治疗等，但这些治疗方法会产生副作用。由此推断，该段回答了F选项“How is cancer treated?”所提出的问题，故F为正确答案。

2、Smallpox virusIt\'s now a fair bet that we will never see the total extinction of the smallpox virus. The idea was to cap the glorious achievement of 1980, when smallpox was eradicated in the wild, by destroying the killer virus in the last two labs that are supposed to have it—one in the US ａｎｄ　one in Russia. If smallpox had truly gone from the planet, what point was there in keeping these reserves?In reality, of course, it was naive to imagine that everyone would let go of such a potential weapon. Undoubtedly several nations still have a few vials. ａｎｄ　the last “official” stocks of live virus bred mistrust of the US ａｎｄ　Russia, fｏｒno obvious gain.Now American researchers have found an animal model of the human disease, opening the way fｏｒtests on new treatments ａｎｄ　vaccines. So one again there\'s a good reason to keep the virus—just in case the disease puts in a reappearance.How do we deal with the mistrust of the US ａｎｄ　Russia? Simple. Keep the virus ____ international auspices in a well-guarded UN laboratory that\'s open to all countries. The US will object, of course, just as it rejects a multilateral approach to just about everything. But it doesn\'t mean the idea is wrong. If the virus is useful, then let\'s make it the servant of all humanity—not just a part of it.【单选题】

A.under

B.in

C.on

D.or

正确答案:A

答案解析:此题考查固定搭配。under?the?auspices:赞同，支持。故A为正确答案。

3、MemoriesMost episodes of absent-mindedness forgetting where you left something ｏｒwondering 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 majｏｒimpact on recalling it later. Failure to encode properly can create annoying situations. If you put your mobile phone in a pocket, fｏｒexample, 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. " ____. "Lack of interest can also lead to absent-mindedness. "A man who can recite sports statistics from 30 years ago," says Zelinski, "may not remember to ｄｒｅｐa 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】

A.Encoding, Schacter says, is a special way of paying attention to an event that has a majｏｒimpact on recalling it later

B.Rather, you didn\'t give your memory system the information it needed

A.keep

B.put

C.destroy

D.eradicate

正确答案:A

答案解析:keep?the?virus:保存病毒。put?the?virus是不正确的表达，后面必须有地点状语。如：You?can?put?the?virus?in?a?bottle．??destroy?the?virus和eradicate?the?virus都是“消灭病毒”的意思，跟后半句话在意思上是矛盾的。故A为正确答案。

5、College Night Owls Have Lower GradesCollege students who are morning people tend to get better grades than those who are night owls(晚睡的人), according to University of North Texas researchers.They had 824 undergraduate(大学本科生的) students complete a health survey that in cluded questions about sleep habits ａｎｄ　daytime functioning, ａｎｄ　found that students who are morning people had higher grade point averages(GPAs) than those who are night people."The finding that college students who are evening types have lower GPAs is a very important finding, sure to make its way into undergraduate psychology texts in the near future, along with the research showing that memory is improved by sleep," study co - authｏｒDaniet J. Taylｏｒsaid in a prepared statement."Further, these results suggest that it might be possible to improve academic performance by using chronotherapy (时间疗法) to help students retrain their biological clock to become more morning types," Taylｏｒsaid.The research was expected to be presented Monday at SLEEP, the annual meeting of the Associated Professional (专业的) Sleep Societies, in Baltimore.In other findings expected to be heard at the meeting, University of Colorado researchers found a significant association between insomnia (失眠) ａｎｄ　a decline in college students\' academic performance.The study included 64 psychology, nursing ａｎｄ　medical students, average age 27. 4 years, who were divided into two groups—low GPAs ａｎｄ　high GPAs.Among those with low GPAs,69.7 percent had trouble falling asleep,53.1 percent experienced leg kicks ｏｒtwitches (痉挛) at night, 65.6 percent reported waking at night ａｎｄ　having trouble falling back to sleep, ａｎｄ　72.7 percent had difficulty concentrating during the day."In college students, the complaint of difficulty concentrating during the day continues to have a considerable impact on their ability to succeed in the classroom," study authｏｒDr. James F. Pagel said in a prepared statement. "This study showed that disordered sleep has significant harmful effects on a student\'s academic performance, including GPAs."In the first study, students who stay up late ______.【单选题】
