1、Cancer
Cancer 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 (惡性的) 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 (化療), 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.
Paragraph 2____.
【單選題】
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
正確答案:E
答案解析:第二段主題句為第一句,其意思是:科學家研究證明,癌癥是由正常情況下控制細胞生長和死亡的基因發生突變引起的。由此推斷,該段回答了E選項“What causes cancer?”所提問題,故E為正確答案。
2、Smallpox virus
It'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, for no obvious gain.
Now American researchers have found an animal model of the human disease, opening the way for tests 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 under 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 ____ useful, then let's make it the servant of all humanity—not just a part of it.
【單選題】
A.will?be
B.would?be
C.is
D.are
正確答案:C
答案解析:本句是個條件句。從句中動詞一般用現在時表示“未來”。這就排除了will?be和would?be。virus是單數,因此D也不正確。故C為正確答案。
3、Human Heart Can Make New Cells
Solving a longstanding mystery, scientists have found that the human heart continues to generate new cardiac cells throughout the life span, although the rate of new cell production slows with age.
The finding, published in the April 3 issue of Science, could open a new path for the treatment of heart diseases such as heart failure and heart attack, experts say.
"We find that the beating cells in the heart, cardiomyocytes, are renewed," said lead researcher Dr. Jonas Frisen, a professor of stem cell research at the Karolinska Institute in Stockholm, Sweden. "It has previously not been known whether we were limited to the cardiomyocytes we are born with or if they could be renewed," he said.
The process of renewing these cells changes over time, Frisen added. In a 20-year-old, about 1 percent of cardiomyocytes are exchanged each year, but the turnover rate decreases with age to only 0. 45 percent by age 75,
"If we can understand how the generation of new cardiomyocytes is regulated, it may be potentially possible to develop pharmaceuticals that promote this process to stimulate regeneration after for example, a heart attack, "Frisen said.
That could lead to treatment that helps restore damaged hearts.
A lot of people suffer from chronic heart failure," noted co-author Dr. Ratan Bhardwaj.
Ratan Bhardwaj, also from the Karolinska Institute. "Chronic heart failure arises from heart cells dying," he said.
With this finding, scientists are "opening the door to potential therapies to having ourselves heal ourselves," Bhardwaj said. "Maybe one could devise a pharmaceutical agent that would make heart cells make new and more cells to overcome the problem they are facing. "
But barriers remain. According to Bhardwaj, scientists do not yet know how to increase heart cell production to a rate that would replace cells faster than they are dying off, especially in older patients with heart failure. In addition, the number of new cells the heart produces was estimated using healthy hearts-whether the rate of cell turnover in diseased hearts is the same remains unknown.
The human heart stops producing cardiac cells____.【單選題】
A.when a person becomes old
B.as soon as a person gets sick
C.immediately after a person is born
D.once a person dies
正確答案:D
答案解析:根據是第一段中:. . . the human heart continues to generate new cardiac cells throughout the life span。在人的整個生命進程中,其心臟不斷產生新的心肌細胞。言外之意,這個過程直到人死才會停止。
4、The Ideal Husband
Science now might be able to explain women's fascination with Brad Pitt's face and George Clooney's eyes. Women seem to ____ potential mate by how masculine their features are, new research shows. Men with square jaws and well-defined brow ridges are seen as good short-term partners, while those with more feminine traits such as a rounder face and fuller lips are perceived as better long-term mates.
In the study by Daniel Kruger at the US's University of Michigan, 854 subjects viewed a series of male head shots that had been digitally changed to exaggerate or minimize masculine traits. They then . answered questions about how they expected the men in the photos to behave.
Most participants said that those with more masculine features were likely to be risky, competitive, and more apt to fight, challenge bosses, cheat on spouses and put less effort into parenting. Those with more feminine faces were seen as good parents and husbands, hard workers and emotionally supportive mates.
But, despite all the negative characteristics, when asked who they would choose for a short-term relationship, women selected the more masculine looking men. Brad and George, both chiseled jaws and well-defined brows, then would be good for a brief romance, not for something longer.
The study was published in the December issue of the US journal Personal Relationships.
Kruger said that from an evolutionary perspective, this makes sense. The key is testosterone, the hormone responsible for the development of masculine facial features and other sexual characteristics. It has been found to affect the body's ability to fight disease: men with high levels of the hormone are typically strong and healthy- traits women want to pass on to their children.
However, increased testosterone has also been linked to cheating and violence in relationships. So, these men might produce high quality offspring, but they don't always make great parents or faithful mates, Kruger says.
The scientific community have shown skepticism toward physiognomy, which links facial characteristics to certain behavioral traits. But Kruger argues that the research is a valuable tool for understanding mating strategies. And, of course, for explaining why Tony Leung and Takeshi Kanesshiro have millions of female fans. It might have to do with their genes. Or something to do with ours.
【單選題】
A.make
B.judge
C.date
D.meet
正確答案:B
答案解析:這四個詞的意思是:make:做;judge:判斷;date:約會;meet:見面。本文的主題是講女人找伴侶。從所在句子的表示方式的介詞短語by how masculine their features are(根據他們男性特征的情況),選擇judge在語義上比較一致。

9、Happy Marriage, Happy Heart
Happily married people have lower blood pressure than unhappily married people or singles, a Brigham Young University study says.
On the other hand, even having a supportive social network did not translate into a blood pressure benefit for singles or unhappily married people, according to the study.
"There seems to be some unique health benefits from marriage. It's not just being named that benefits health-what's really the most protective of health is having a happy marriage," study author Julianne Holt Lunstad, a psychologist who specializes in relationships and health, said in a prepared statement.
The study included 204 married and 99 ____ adults who wore portable blood - pressure monitors for 24 hours. The monitors recorded blood pressure at random intervals and provided a total of about 72 readings.
"We wanted to capture participants' blood pressure doing whatever they normally do in everyday life. Getting one or two readings in a clinic is not really representative of the fluctuations (波動) that occur throughout the day," Holt Lunstad said.
Overall, happily married people scored four points lower on the blood pressure readings than single adults. The study also found that blood pressure among married people, especially those in happy marriages dropped more during sleep than in single people.
"Research has shown that people whose blood pressure remains high throughout the night are at much greater risk of heart disease than people whose blood pressure drops," Holt Lunstad said.
The study was published in the March 20 issue of the journal Annals (年刊) of Behavioral Medicine.
The study also found that unhappily married adults have higher blood pressure than both happily married and single adults.
Holt Lunstad noted that married couples can encourage healthy habits in one another, such as eating a healthy diet and having regular doctor visits. People in happy marriages also have a source of emotional support, she said.
【單選題】
