1、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 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 can come back 10 years after you were first diagnosed.【单选题】

2、Parkinson's Disease
1 Parkinson's disease affects the way you move. It happens when there is a problem with certain nerve cells in the brain. Normally, these nerve cells make an important chemical called dopamine. Dopamine sends signals to the part of your brain that controls movement. It lets your muscles move smoothly and do what you want them to do. When you have Parkinson's, these nerve cells break down. Then you no longer have enough dopamine, and you have trouble moving the way you want to.
2 No one knows for sure what makes these nerve cells break down. But scientists are doing a lot of research to look for the answer. They are studying many possible causes, including aging and poisons in the environment. Abnormal genes seem to lead to Parkinson's disease in some people. But so far, there is not enough proof to show that it is always inherited.
3 Tremor may be the first symptom you notice. It is one of the most common signs of the disease, although not everyone has it. More importantly, not everyone with a tremor has Parkinson's disease. Tremor often starts in just one arm or leg or only on one side of the body. It may be worse when you are awake but not moving the affected arm or leg. It may get better when you move the limb or you are asleep. In time, Parkinson's affects muscles all through your body, so it can lead to problems like trouble swallowing or constipation. In the later stages of the disease, a person with Parkinson's may have a fixed or blank expression, trouble speaking, and other problems. Some people also have a decrease in mental skills (dementia).
4 At this time, there is no cure for Parkinson's disease. But there are several types of medicines that can control the symptoms and make the disease easier to live with. You 'may not even need treatment if your symptoms are mild. Your doctor may wait to prescribe medicines until your symptoms start to get in the way of your daily life. Your doctor will adjust your medicines as your symptoms get worse. You may need to take several medicines to get the best results.

3、Smallpox virus
It's now a fair bet that we will never see the total extinction of the smallpox virus. The idea was to cap the glorious achievement of 1980, when smallpox was eradicated in the wild, by destroying the killer virus in the last two labs that are supposed to have it—one in the US and one in Russia. If smallpox had truly gone from the planet, what point was there in keeping these reserves?
In reality, of course, it was naive to imagine that everyone would let go of such a potential weapon. Undoubtedly several nations still have a few vials. And the last “official” stocks of live virus bred mistrust of the US and Russia, for no obvious gain.
Now American researchers have found an animal model of the human disease, opening the way for tests on new treatments and vaccines. So one again there's a good reason to ____ the virus—just in case the disease puts in a reappearance.
How do we deal with the mistrust of the US and Russia? Simple. Keep the virus under international auspices in a well-guarded UN laboratory that's open to all countries. The US will object, of course, just as it rejects a multilateral approach to just about everything. But it doesn't mean the idea is wrong. If the virus is useful, then let's make it the servant of all humanity—not just a part of it.
【单选题】

A.keep

B.put

C.destroy

D.eradicate

正确答案:A

答案解析:keep?the?virus:保存病毒。put?the?virus是不正确的表达，后面必须有地点状语。如：You?can?put?the?virus?in?a?bottle．??destroy?the?virus和eradicate?the?virus都是“消灭病毒”的意思，跟后半句话在意思上是矛盾的。故A为正确答案。

4、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。

5、Musical Training Can Improve Communication Skills
American scientists say musical training seems to improve communication skills and language retardation. They found that developing musical skills involves the same process in the brain as learning how to speak. The scientists believe that could help children with learning disabilities.
____. She says musical training involves putting together different kinds of information, such as hearing music, looking at musical notes, touching an instrument and watching other musicians. This process is not much different from learning how to speak. Both involve different senses.
She further explains musical training and learning to speak each make us think about what we are doing. She says speech and music pass through a structure of the nervous system called the brain stem. The brain stem controls our ability to hear. Until recently, experts have thought the brain stem could not be developed or changed. But Professor Kranss and her team found that musical training can improve a person's brain stem activity.
The study involved individuals with different levels of musical ability. They were asked to wear an electrical device that measures brain activity. The individuals wore the electrode while they watched a video of someone speaking and a person playing a musical instrument ---- the cello.
Professor Krauss says cellos have sound qualities similar to some of the sounds that are important with speech. The study found that the more years of training people had, the more sensitive they were to the sound and rhythm of the music. Those who were involved in musical activities were the same people in whom the improvement of sensory events was the strongest. It shows the importance of musical training to children with learning disabilities. She says using music to improve listening skills could mean they hear sentences and understand facial expressions better.
