1、When a disease of epidemic proportions rips into the populace, scientists immediately get to work, trying to locate the source of the affliction and find ways to combat it. Oftentimes, success is achieved, as medical science is able to isolate the parasite, germ or cell that causes the problem and finds ways to effectively kill or contain it. In the most serious of cases, in which the entire population of a region or country may be at grave risk, it is deemed necessary to protect the entire population through vaccination, so as to safeguard lives and ensure that the disease will not spread.
The process of vaccination allows the patient's body to develop immunity to the virus or disease so that, if it is encountered, one can ward it off naturally. To accomplish this, a small weak or dead strain of the disease is actually injected into the patient in a controlled environment, so that his body's immune system can learn to fight the invader properly. Information on how to penetrate the disease's defenses is transmitted to all elements of the patient's immune system in a process that occurs naturally, in which genetic information is passed from cell to cell. This makes sure that, should the patient later come into contact with the real problem, his body is well equipped and trained to deal with it, having already done so before.
There are dangers inherent in the process, however. On occasion, even the weakened version of the disease contained in the vaccine proves too much for the body to handle, resulting in the immune system succumbing, and, therefore, the patient's death. Such is the case of the smallpox vaccine, designed to eradicate the smallpox epidemic that nearly wiped out the entire Native American population and killed massive numbers of settlers. Approximately l in 10,000 people who receives the vaccine contract the smallpox disease from the vaccine itself and dies from it. Thus, if the entire population of the United States were to receive the Smallpox Vaccine today, 3,000 Americans would be left dead.
Fortunately, the smallpox virus was considered eradicated in the early 1970's, ending the mandatory vaccination of all babies in America. In the event of a re-introduction of the disease, however, mandatory vaccinations may resume, resulting in more unexpected deaths from vaccination. The process, which is truly a mixed blessing, may indeed hide some hidden curses.
The purpose of the author in writing this passage is____.

2、A Tale of Scottish Rural Life
Lewis Grassic Gibbon's Sunset Song (1932) was voted "the best Scottish novel of all time" by Scottish's reading public in 2005. Once considered shocking for its frank description of aspects of the lives of Scotland's poor rural farmers, it has been adapted for stage, film, TV and radio in recent decades.
The novel is set on the fictional estate of Kinraddie, in the farming country of the Scottish northwest in the years up to and beyond World War I. At its heart is the story of Chris, who is both part of the community and a little outside it.
Grassic Gibbon gives us the most detailed and intimate account of the life of his heroine. We watch her grow through a childhood dominated by her cruel but hard-working father; experience tragedy (her mother's suicide and murder of her twin children); and learn about her feelings as she grows into woman. We see her marry, lose her husband, then marry again. Chris has seemed so convincing a figure to some female readers that they cannot believe that she is the creation of a man.
But it would be misleading to suggest that this book is just about Chris. It is truly a novel of a place and its people. Its opening section tells of Kinraddie's long history, in a language that imitates the place's changing patterns of speech and writing.
The story itself is amazingly full of characters and incidents. It is told from Chris' point of view but also from that of the gossiping community, a community where everybody knows everybody else's business and nothing is ever forgotten.
Sunset Song has a social theme too. It is concerned with what Grassic Gibbon perceives as the destruction of traditional Scottish rural life first by modernization and then by World War I. Gibbon tried hard to show how certain characters resist the war. Despite this, the war takes the young men away, a number of them to their deaths. In particular, it takes away Chris' husband, Ewan Tavendale. The war finally kills Ewan, but not in the way his widow is told In fact, the Germans aren't responsible for his death, but his own side. He is shot because he is said to have run away from a battle.
If the novel is about the end of one way of life it also looks ahead, it is a "Sunset Song" but is concerned too with the new Kinraddie, indeed of the new European world Grassic Gibbon went on to publish two other novels about the place that continue its story.
Which statement is NOT true of Chris?【单选题】

A.She is the heroine of Sunset Song.

B.She had a miserable childhood.

C.She is the creation of a man.

D.She married only once.

正确答案:D

答案解析:A:她是《日落歌》中的女主人公；B：她的童年很苦；C：她由一个男人创作出来的；D:她只结过一次婚。D不对。第三段有这么一句话：We see her marry，lose her husband， then marry again. 我们看见她结婚，失去丈夫，后来又结婚。

3、Outside-the-classroom Learning Makes a Big Difference
Putting a bunch of college students in charge of a $300,000 Dance Marathon, fundraiser surely sounds a bit risky. When you consider the fact that the money is supposed to be given to. Children in need of medical care, you might call the idea crazy.
Most student leaders don't want to spend a large amount of time on something they care little about, said 22-year-old University of Florida student Darren Heitner. He was the Dance Marathon's operations officer for two years.
Yvonne Fangmeyer, director of the student organization office at the University of Wisconsin, conducted a survey in February of students involved in campus organizations. She said the desire for friendship was the most frequently cited reason for joining.
At large universities like Fangmeyer's, which has more than 40,000 students, the students, first of all, want to find a way to "belong in their own comer of campus".
Katie Rowley, a Wisconsin senior, confirms the survey's findings. "I wanted to make the campus feel smaller by joining an organization where I could not only get involved on campus but also find a group of friends. "
All of this talk of friendship, however, does not mean that students aren't thinking about their resumes. "I think that a lot of people do join to 'fatten up their resume'," said Heitner. "At the beginning of my college career, I joined a few of these organizations, hoping to get a start in my leadership roles. "
But without passion student leaders can have a difficult time trying to weather the storms that come. For example, in April, several student organizations at Wisconsin teamed up for an event designed to educate students about homelessness and poverty. Student leaders had to face the problem of solving disagreements, moving the event because of rainy weather, and dealing with the university's complicated bureaucracy.
"Outside-of the classroom learning really makes a big difference," Fangmeyer said.
American students join campus organizations mostly for ____.【单选题】

A.making a difference

B.gaining experience

C.building friendship

D.improving their resumes

正确答案:C

答案解析:答案可以从第三段找到。第三段是这么说的：威斯康星大学学生组织办公室主任Yvonne Fangmeyer在二月组织了一次学生参加校园组织的调查。她说，寻求友谊是最经常出现的理由。

4、Egypt Felled by Famine
Even ancient Egypt's mighty pyramid builders were powerless in the face of the famine that helped bring down their civilization around 2180 BC. Now evidence gleaned from mud deposited by the River Nile suggests that a shift in climate thousands of kilometers to the south was ultimately to blame and the same or worse could happen today.
The ancient Egyptians depended on the Nile's annual floods to irrigate their crops. But any change in climate that pushed the African monsoons southwards out of Ethiopia would have diminished these floods.
Dwindling rains in the Ethiopian highlands would have meant fewer plants to stablize the soil. When rain did fall it would have washed large amounts of soil into the Blue Nile and into Egypt, along with sediment from the White Nile.
The Blue Nile mud has a different isotope signature from that of the White Nile. So by analyzing isotope differences in mud deposited in the Nile Delta, Michael Krom of Leeds University worked out what proportion of sediment came from each branch of the river.
Krom reasons that during periods of drought, the amount of the Blue Nile mud in the river would be relatively high. He found that one of these periods, from 4,500 to 4,200 years ago, immediately predates the fall of the Egypt's Old Kingdom.
The weakened waters would have been catastrophic for the Egyptians. " Changes that affect food supply don't have to be very large to have a ripple effect in societies," says Bill Ryan of the Lamont Doberty Earth Observatory in New York.
"Similar events today could be even more devastating," says team member Daniel Stanley, a geoarchaeologist from the Smithsonian Institution in Washington, D C. " Anything humans do to shift the climate belts would have an even worse effect along the Nile system today because the populations have increased dramatically. "
Which of the following factors was ultimately responsible for the fall of the civilization of ancient Egypt?
【单选题】

A.Change of climate.

B.Famine.

C.Flood.

D.Population growth.

正确答案:A

答案解析:A：气候的变化。第一段中有这样一个子句… a shift in climate… was ultimately to blame…最终须归咎于气候的变化。在第一题的题解中，我们提到了“饥荒”与“古埃及文明毁灭”的关系。但“饥荒”是表层的因素，“气候的变化”才是古埃及文明毁灭的深层的因素。因此A是正确的答案。B：饥荒。C：水灾。D：人口增长。

5、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 finding could prove to be useful to ____.【单选题】

A.the analysis of cardiac cells

B.the prevention of chronic diseases

C.the treatment of heart disease

D.the study of longstanding mysteries

正确答案:C

答案解析:根据是第二段中：The finding，…，could open a new path for the treatment of heart diseases这一研究成果将为心脏病的医治开拓新的途径。
