1、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____.【单选题】

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

正确答案:D

答案解析:根据是第一段中：. . . the human heart continues to generate new cardiac cells throughout the life span。在人的整个生命进程中，其心脏不断产生新的心肌细胞。言外之意，这个过程直到人死才会停止。

2、Baseball
There 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.
We can safely conclude that the author ____.【单选题】

A.likes football

B.hates football

C.hates baseball

D.likes baseball

正确答案:D

答案解析:在本文中，作者主要探讨了垒球的特征及欣赏，作者着重指出的是： 只有根据垒球的特征来欣赏它，才能体会到它的魅力。在他看来，观察到垒球比赛中运动员的各种动作、垒球位之间的关系等是欣赏它的关键（第三段第二句）。只有从整体来把握它，才能看到每一个小的动作、每一个眼神乃至于“静止”的意义，也只有这样，才能全身心地投入比赛中，欣赏到它的魅力。可见，作者对垒球有很深的理解而且非常喜爱垒球。

3、Early childhood education
In a time of low academic achievement by children in the United States, many Americans are turning to Japan, a country of high academic achievement and economic success, for possible answers. However, the answers provided by Japanese preschools are not the ones Americans expected to find in most Japanese preschools, surprisingly little emphasis is put on academic instruction. In one investigation, 300 Japanese and 210 American preschool teachers, child development specialists, and parents were asked about various aspects of early childhood education. Only 2 percent of the Japanese respondents listed "to give children a good start academically" as one of their top three reasons for a society to have preschools. In contrast, over half the American respondents chose this as one of their top three choices. To prepare children for successful careers in first grade and beyond, Japanese schools do not teach reading, writing, and mathematics, but rather skills such as persistence, concentration, and the ability to function as a member of a group. The vast majority of young Japanese children are taught to read at home by their parents.
In the recent comparison of Japanese and American preschool education, 91 percent of Japanese respondents chose providing children with a group experience as one of their top three reasons for a society to have preschools. Sixty-two percent of the more individually oriented (强调个性发展的) Americans listed group experience as one of their top three choices. An emphasis on the importance of the group seen in Japanese early childhood education continues into elementary school education.
Like in America, there is diversity in Japanese early childhood education. Some Japanese kindergartens have specific aims, such as early musical training or potential development. In large cities, some kindergartens are attached to universities that have elementary and secondary schools. Some Japanese parents believe that if their young children attend a university-based program, it will increase the children＇s chances of eventually being admitted to top-rated schools and universities. Several more progressive programs have introduced free play as a way out for the heavy intellectualizing in some Japanese kindergartens.
Why do some Japanese parents send their children to university based kindergartens?【单选题】

A.They can do better in their future studies.

B.They can accumulate more group experience there.

C.They can be individually oriented when they grow up.

D.They can have better chances of getting a first-rate education.

正确答案:D

答案解析:此题可以从全文的最后一段的第四句话得出答案。其中top-rated与first-rate意思相同。

4、15 Million Americans Suffer from Social Anxiety Disorder
Social anxiety disorder prevents some 15 million Americans from leading normal social and romantic lives, a new survey finds.
The disorder leaves many isolated, ashamed and often misdiagnosed. Thirty-six percent of those with social anxiety disorder have symptoms for 10 years or more before seeking help, the Anxiety Disorders Association of America reports.
"Social anxiety disorder is when somebody has an intense, persistent and irrational fear of social or performance situations," Jerilyn Ross, the association＇s president and CEO, said during a teleconference Wednesday.
"The condition causes people to avoid common, everyday situations and even other people for fear of being judged or criticized or humiliated or embarrassing themselves," Ross said.
Social anxiety disorder can interfere with daily routines and job performance, Ross noted. "It also makes it very difficult for people to develop friends and romantic partnerships," she said.
People with this disorder recognize their fear is excessive and irrational, Ross noted. "But they feel powerless to do anything about it," she said.
Social anxiety disorder can start in the early teens, Dr. Mark H. Pollack, director of the Center for Anxiety and Traumatic Stress Disorders and a professor of psychiatry at Harvard Medical School, said during the teleconference.
"This is a disorder that starts affecting people early on," Pollack said. "The typical age of onset is early adolescence, age 12 or 13, and many individuals report a history of anxiety dating back to earlier childhood."
The disorder also has physical symptoms, including heart palpitations, feelings that their throat will close up, sweating, blushing, faintness, trembling and stammering, Ross said.
Among people with the disorder, 75 percent said the condition affected their ability to do normal activities. In addition, 69 percent said they didn＇t want people to think they were crazy, and 58 percent said they were embarrassed by their condition, Ross said.
However, when the condition is diagnosed and treated, many reported improvement in their lives. In fact, 59 percent who were receiving treatment said treatment had a positive effect on their ability to have a romantic relationship. In addition, 39 percent who had received treatment said knowing that treatment can be successful aided their decision to get help, Ross noted.
What do people with social anxiety disorder think of their fear?【单选题】

A.They think it＇s beyond their control.

B.They think it＇s beneficial.

C.They think it＇s controllable.

D.They think it＇s justified.

正确答案:A

答案解析:短文的第六段说，患有social anxiety disorder的人意识到他们的恐惧是过分的和非理性的，然而却对此无能为力。

5、Online Cancer Chat with a Safety Net
Cancer Research UK has launched an online chat forum for cancer patients to swap (变换) stories and share experiences on how to cope with such a devastating disease.
But Cancer Chat is a forum with a difference: it has an information safety net.
This means that a Cancer Research UK team will keep a watching brief to ensure that patients are not subjected to rogue (劣等的) "cancer cures" or scientifically unsound information.
Anyone can have access to the messages posted on Cancer Chat, but if people wish to post a message, they will need to register.
And Rebekah Gibbs, cancer patient and star of TWs Casualty, has pledged her support for the new project. "I think Cancer Chat is a brilliant idea," she said. "I have written a public diary about what I went through with breast cancer and I have had such a heart - warming response from other people going through the same thing."
The idea of a Cancer Chat forum means you can share information about treatment and side effects and you can really open up about your feelings online in a way that can be difficult when talking to close friends and family. And with Cancer Research UK monitoring the forum, people can be reassured about the quality of information being exchanged.
Cancer Chat will also encourage its users to check out any cancer questions on its CancerHelp UK website, which is specially designed to give patients and their families 6,000 pages of up - to - date information that is easy to understand and explains a wide range of treatments for different types of cancer and gives details of clinical trials. There is also a UK database of cancer clinical trials.
The award - winning website attracts around one million visitors a month and Cancer Research UK hopes that some of these visitors will also want to post comments on the Cancer Chat forum.
For those who do not have access to computers and have questions about cancer, the charity＇s team of cancer information nurses are available during office hours to talk over patients＇ concerns on the phone.
Cancer Chat is different from other forums chiefly in that ______.【单选题】

A.it has the support of a famous actress

B.it provides a huge amount of data

C.it is a source of reliable information

D.it attracts a great number of visitors

正确答案:C

答案解析:本题有一定难度，需要认真吃透原文句意，答案依据是文章第二段，…it has an information safety net，谈到癌症闲谈论坛有不一样的地方，就是它的信息来源安全可靠，回来看选项，C项和原文句意相符，是答案。
