Dr. Jack M. Gwaltney, Jr. a professor at the University Of Virginia School Of Medicine infected six student volunteers with virus, the most common cause of colds. A few days later, when they were coughing and sneezing, he gathered 37 more people and divided them into three groups. Group 1 members spent three days and nights in the same room with one of the infected students, separated by a screen so they couldn't touch one another. Group 2 sat around a table while an infected volunteer talked, coughed and sang to them. Group 3 held hands with an infected student for ten seconds, and then touched their own noses or eyes.
Although most scientists at the time, the mid-70s, believed colds were spread by virus-laden droplets spread through the air when infected people coughed or sneezed, Gwaltney suspected physical contact might play an important role. Sure enough, of the 15 people who had touched a student volunteer, 11 became infected—compared with only one of those who had been sitting at the table, and none who had spent three days and nights together.
"The best evidence we have is that hand-to-hand contact is the most efficient way of transmitting virus," says Gwaltney. The study was one of a series that helped establish Gwaltney's reputation as a leading authority. Dr. Robert Couch says, "It would not be inappropriate to call him Mr. Common Cold."
When Gwaltney is asked how close scientists are to finding a cure, he replies: "If you mean ‘get rid of’, I don't think we're going to be able to do that with cold viruses any time soon. But if you look in the dictionary, you'll see that 'cure' is explained as a successful treatment. And we're not just getting more effective at treating the symptoms (症状)—we're getting at the root cause too. "Dr. Jack M. Gwaltney conducted the experiment in order to__________.

| B．infect the student volunteer |

Almost everyone suffers from a headache sometimes.But some people suffer from repeated, frequent headaches.
What is headache? What causes it? What can be done about a headache? What research is being done on headaches?
The dictionary defines(下定义) headache simply as “a pain in the head.” What most people mean by headache is a pain which lasts several minutes or hours.It covers the whole head, or one side of it, or perhaps the front or the back of the head.To add to the confusion(困惑) about a definition, some people call tight feeling in the head a headache.
A headache is important because it can be the first warning of a serious condition which probably could be controlled if discovered early.If a person removes the warning, day after day, with a pain-killer, he may pass the point of easy control.
The professional name for covering up a symptom(症状) is “masking” (遮蔽).A headache specialist once said, “Masking symptoms is not the best way of treatment.” He compared taking a pain-killer for a headache before a cause is known with taking iron pills for anemia(贫血症) while bleeding continues undiscovered.He added, “Sometimes it is wiser to stand still than to advance in darkness.”
A headache is important also because it affects normal, happy living.The employee with a headache does less work.In a flash of temper he may upset his fellow workers or customers, causing a direct or indirect loss to his organization.The mother with a headache suffers and disturbs the family.She upsets her husband and children.Which is true according to the passage?

After eating his first good meal in weeks, he found himself lying to the waiter, telling him he had lost his wallet.The waiter, who was also the owner, walked behind the chair where the young man had been sitting.He bent down, and came up with a $20 bill that looked as if it had fallen on the floor and said, “Son, you must have dropped this,” the owner said.The young man couldn’t believe his luck!

Why do men live a shorter life than women? The latest research indicates that men’s hearts going into a rapid decline when they reach middle age could be the cause.
The research of ageing on the heart has shown that women’s longevity may be linked to the fact that their hearts do not lose much pumping power with age.
“We have found that the power of the male heart falls by 20-25 percent between 20 and 70 years of age,” said the head of the study, Samantha of Liverpool John Moores University in the UK.
“Within the heart there are millions of cells which make it beat.Between the ages of 20 and 70, one-third of those cells die and are not replaced in men ,” said Samantha.“This is part of the ageing process.”
What amazes scientists is that the female heart suffers very little loss of these cells.A healthy 70-year-old woman’s heart could work almost as perfectly as a 20-year-old one’s.
“This gender （性别）difference might give the reason why men live shorter than women,”said Samantha.They studied over 250 healthy men and women between the ages of 17 and 80, who are mainly healthy persons so as to reduce the influence of disease.“The team has yet to think about why ageing suffers a greater loss on the male heart,” said Samantha.
But there is also good news -- men can enjoy the health of their hearts with regular exercise.Samantha stressed that women should also take regular exercise to stop their leg muscles getting weaker as they age.The underlined word “longevity” in the second paragraph means “________”.
| A．health | B．long life | C．ageing | D．effect |
The text mainly talks about ________.
| A．men’s heart cells | B．women’s ageing process |

According to the text, the UK scientists have known that ________.
| A．men have fewer cells than women when they are born |
| B．women can produce the cells that make the heart beat |
| C．the female heart suffers less loss of the cells with age |
| D．women will never suffer the loss of pumping power with age |
If you want to live a long life, you should ________.
| A．enable your heart to beat much faster |
| B．think about the reason for ageing |
| C．take regular exercise to keep your heart healthy |
| D．stop your cells from being lost |
