1、 More Than 8 Hours Sleep Too Much of a Good Thing 1 Although the dangers of too little sleep are widely known, new research suggests that people who sleep too much may also suffer the consequences. 2 Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep, as well as a number of other sleep problems, than people who sleep 8 hours a night. People who slept only 7 hours each night also said they had more trouble falling asleep arid feeling refreshed after a night\'s sleep than 8-hour sleepers. 3 These findings, which Dr. Daniel Kripke reported in the journal Psychosomatic Medicine, demonstrate that people who want to get a good night\'s rest may not need to set aside more than 8 hours a night. He added that "it might be a good idea" for people who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed, but cautioned that more research is needed to confirm this. 4 Previous studies have shown the potential dangers of chronic shortages of sleep, for instance, one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more. 5 For the current report, Kripke reviewed the responses of 1,004 adults to sleep questionnaires, in which participants indicated how much they slept during the week and whether they experienced any sleep problems. Sleep problems included waking in the middle of the night, arising early in the morning and being unable to fall hack to sleep, and having fatigue interfere with day-to-day functioning. 6 Kripke found that people who slept between 9 and 10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours. In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed. As evidence, he added that one way to help insomnia is to spend less time in bad. "It stands to reason that if a person spends too long a time in bed, then they\'ll spend a higher percentage of time awake," he said. One of the sleep problems is walking in the middle of the night, unable to____.【单选题】

A.fall asleep again

B. become more energetic the following day

C.sleep less than 9 hours

D.confirm those serious consequences

E.suffer sleep problems

F.sleep more than 10 hours

正确答案:A

答案解析:本题答案的依据是第五段第二句：Sleep problems included waking in the middle of the night, arising early in the morning and being unable to fall back to sleep.

2、Breast Cancer Deaths Record LowThe 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.Breast cancer deaths began to be recorded in the UK in 1971.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:本题难度不大，答案依据比较明显，带着题干信息词回文章定位，答案依据在文章第三段这一句：The previous lowest figure had been recorded in 1971-the year records began一很明显，破折号里谈到记录是从这一年开始的，也就是乳腺癌记录最低的1971年，所以本题正确，答案是A。

3、Nurse! I Want My MummyWhen a child is ill in hospital, a parent\'s first reaction is to be with them.Most hospitals now allow parents to sleep overnight with their child, providing a bed or sofa on the ward.But until the 1970s this practice was not only frowned upon (不赞同) — it was actively discouraged. Staff worried that the children would be upset when their parents left, and so there was a blanket (通用的) ban.A concerned nurse, Pamela Hawthorn, disagreed and her study "Nurse, I want my mummy!" published in 1974, changed the face "paediatric (儿科的) nursing.Martin Johnson, a professor of nursing at the University of Salford, said that the work of nurses like Pamela had changed the face of patient care."Pamela\'s study was done against the ____ of a lively debate in paediatrics and psychology as to the degree women should spend with children in the outside world and the degree to which they should be allowed to visit children in hospital.""The idea was that if mum came to visita small child in hospital the child would be upset and inconsolable (无法安慰的) for hours. ""Yet the nurse noticed that if mum did not come at all the child stayed in a relatively stable state but they might be depressed. ""Of course we know now that they had almost given up hope that mum was ever coming back.""To avoid a little bit of pain they said that no one should visit.""But children were alone and depressed, so Hawthorn said parents should be allowed to visit."Dr. Peter Carter, chief executive and general secretary of the Royal College of Nursing, said her work had been seminal (开创性的)."Her research put an end to the days when parents handed their children over to strangers at the door of the hospital ward.""As a result of her work, parents are now recognized as partners in care and are afforded the opportunity to stay with their children while they are in hospital, which has dramatically improved both parents\' and children\'s experience of care." 【单选题】

A.field

B.background

C.circle

D.history

正确答案:B

答案解析:本题有一定难度，考查固定搭配against the background的用法，against the background指“在……的背景下”，文章此处是说“Pamela是在儿科学和心理学有关……的热烈争论的背景下做了这项研究”，答案是B。

5、Human Heart Can Make New CellsSolving 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.It is not known yet if the rate of cell turnover in diseased hearts ______.【单选题】

A.is high enough to replace cells faster than they\'re dying off

B.is of any use to researchers

C.is the same as that in healthy hearts

D.changes over time

正确答案:C

答案解析:本题难度不大，答案依据比较明显。带着题干信息词回文章定位，答案依据是文章最后一段最后一句，谈到心脏新细胞的制造数量是按照健康心脏来计算的，但是患病心脏的细胞更新率是否一样还是未知，回来看选项，C项和原文句意相符，是答案。
