1、Importance of Children's Oral Health
February is National Children's Dental(牙齿的) Health Month, but in children good oral(口部的) care is critical every day. The first comprehensive study on the nation's oral health, released recently by the Office of the U. S. Surgeon General, calls dental and oral diseases a "silent epidemic (流行病)", even in children. The report states that more than 51 million school hours are lost each year to dental - related illness. In fact, a recent study pointed to dental care as the most common unmet health need among American children.
To help counter this, the American Academy of Periodontology (牙周病学) (AAP) is launching an effort to educate children and parents about the prevention of dental diseases in children.
"This is important because oral problems can impact self - esteem for children and lead to problems of eating, speaking and attending to learning," said Michael McGuire, president of the AAP.
Common dental problems seen in children are cavities (龋洞) and gingivitis (龈炎), which are found in the majority of U. S. children. "When these problems are not caught early and treated, they can develop into more severe problems and cause unnecessary suffering," said McGuire. "However, much of the time, oral problems are avoidable problems."
In the Rio Grande Valley in Texas, a group of more than 120 dentists(牙医) volunteers to deliver dental care to thousands of low - income children each year with its Mobile Dental Unit that travels from school to school.
"According to the Surgeon General's Report, about 37 percent of children have not had a dental visit before starting school," said McGuire. When children don't see dentists, they miss the opportunity to have problems caught early before they develop into larger, more expensive problems to treat, and parents miss the opportunity to learn how to promote good oral habits in their children.
Only in February should attention be paid to children's oral health.【单选题】

1、Human Heart Can Make New Cells
Solving a longstanding (为时甚久的) mystery, scientists have found that the human heart continues to generate new cardiac(心脏的 ) 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 (心肌细胞), 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 I percent of cardiomyocytes are exchanged each year, but the turnover (更替) 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 (药物) 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, 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 (疗法) 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:本题有一定难度，需要吃透原文句意，答案依据是文章第一段，谈到科学家发现人一生中心脏都会不停地制造新的心肌细胞，尽管新细胞产生的速度随年龄增长而放慢，换句话说，只有人死了，心脏才会停止制造心肌细胞，回来看选项，D项和原文句意相符，是答案。
