2、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.
Chronic heart failure is attributed to ____.【单选题】

A.the dying heart cells

B.the effect of pharmceutical

C.the weight of a patient

D.the life span of a person

正确答案:A

答案解析:倒数第三段说：Chronic heart failure arises from heart cells dying。慢性心衰是由心肌细胞死亡导致的。

3、The old concerns lose importance and some of them vanish altogether.【单选题】

D.renew

正确答案:B

答案解析:vanish与disappear：消失、失踪；develop：发展；linger：徘徊；renew：更新、复原。

4、Breast Cancer Deaths Record Low
The number of women dying from breast cancer has fallen to a record low by dropping under 12,000 a year for the first time since records began.
The Cancer' Research UK data showed that 11.990 women died in the UK in 2007.
The previous lowest figure had been recorded in 1971-the year records began-after which it rose steadily year by year until the late 1980s.
Professor Peter Johnson, Cancer Research UK's chief clinician. said: "It's incredibly encouraging to see fewer women dying from breast cancer now than at any time in the last 40 years, despite breast cancer being diagnosed more often."
"Research has played a crucial role in this progress leading to improved treatments and better management for women with the disease."
"The introduction of the NHS (国民保健制度) breast screening 3 program has also contributed as women are more likely to survive the earlier cancer is diagnosed."
Breast cancer is now the most common cancer in the UK with 45,500 women every year diagnosed with the disease - a 50% rise in 25 years.
The number of deaths peaked in 1989, when 15,625 women died. It then fell by between 200 and 400 deaths each year until 2004.
There was a slight rise in 2005 and then two years of falls.
Dr. Sarah Cant, policy manager at Breakthrough Breast Cancer said: "It is great news that fewer women are dying from breast cancer and highlights the impact of improved treatments, breast screening and awareness of the disease. "
"However, this is still too many women and incidence of the disease is increasing year by year. "
The rising rate of breast cancer diagnosis has been put down to a variety of factors including obesity(肥胖) and alcohol consumption.
Obesity and alcohol consumption may also lead to some other diseases.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:C

答案解析:本题有一定难度，关键在吃透句意。答案依据比较明显，带着题干信息词回文章定位，答案依据在文章最后一段这一句：The rising rate of breast cancer diagnosis has been put down to a variety of factors including obesity and alcohol consumption.谈到乳腺癌确诊率上升和肥胖、过度饮酒有关，但并没有提及肥胖和过量饮酒是否会引发其他疾病，因此本题未提及，答案是C。

5、The two banks have announced plans to merge next year.【单选题】

A.combine

B.close

C.break

D.sell

正确答案:A

答案解析:这两家银行宣布了明年合并的计划。本题难度不大，merge是“合并”，和combine“联合”意思相近，其他三项都是常用词，和答案意义差异大，干扰性不强。本题考查的是combine的引申义。
