Space travel is definitely bad for astronauts’ bones, reducing their bone density(密度) after only a month of weightlessness, according to French research published on Friday.
Laurence Vico and his fellow workers at St Etienne University called for more research into the effects of microgravity, after their study of 15 astronauts from the Russian MIR station showed bone loss continued throughout space flights.
“Bone loss was especially striking in four astronauts, ” the scientists reported in the Lancet Medical Journal.
They measured the bone mineral density (BMD) of bones in the forearm(前臂) and lower leg of the astronauts who had spent one to six months in space.
The BMD loss was significant in the tibia(胫骨) of the lower leg, a weight-bearing bone, but barely changed in the radius(桡骨) of the forearm. “Our results indicate the need to investigate not only different bones, but also different areas of the same bone since not all sites of the skeleton (骨架) are similarly affected by space conditions, ” they added.
Without gravity the body isn’t bearing any weight so there is no need for calcium (钙) which makes bones strong, and it becomes empty into the bloodstream.
The research team suggested in future scientists should try to determine if the loss of bone density was only on weight-bearing bones on longer flights, also the possible recovery after returning to Earth.
1. French scientists did their research on Russian astronauts, because _______.
A. they only cared for the Russian astronauts
B. they were not interested in their own astronauts
C. the Russian government invited them to do their research
D. the Russian astronauts worked in space for a long time
2. Scientists have found that _______.
A. the BMD loss may cause serious illness to astronauts
B. the BMD loss may cause some change in astronauts’ bodies
C. astronauts shouldn’t care about the BMD loss
D. astronauts should take some calcium before space travel
3. What cause the BMD loss to astronauts, according to this passage?
A. The food they eat in space.                     B. The drinks they take in space.
C. The temperature in space.                D. The gravity in space.
4. In the third paragraph, the word “striking” means ______.
A. unusual             B. simple               C. weak                 D. slow

During the interview,Mr Petri said,“You're just the kind of person we need here.You've being wasted in your other job.Give me a call in a day or two.I'm sure we can find a place for you in our organization."Martha was so happy that she almost danced out of the building.

Betty and Harold have been married for years. But one thing still puzzles (困扰) old Harold. How is it that he can leave Betty and her friend Joan sitting on the sofa, talking, go out to a ballgame, come back three and a half hours later, and they're still sitting on the sofa? Talking?
What in the world, Harold wonders, do they have to talk about?
Betty shrugs. Talk? We're friends.
Researching this matter called friendship, Psychologist Lillian Rubin spent two
years interviewing more than two hundred women and men. No matter what their age, their job, their sex, the results were completely clear: women have more friendships than men, and the difference in the content and the quality of those friendships is“marked and unmistakable”.
More than two hirds of the single men Rubin interviewed could not name a best friend. Those who could were likely to name a woman. Yet threequarters of the single women had no problem naming a best friend, and almost always it was a woman. More married men than women named their wife/husband as a best friend, most trusted person, or the one they would turn to in time of emotional distress (感情危机).“Most women,” says Rubin,“identified (认定) at least one, usually more, trusted friends to whom they could turn in a troubled moment, and they spoke openly about the importance of these relationships in their lives.”
“In general,” writes Rubin in her new book,“women's friendships with each other rest on shared emotions and support, but men's relationships are marked by shared activities.” For the most part, Rubin says, interactions (交往) between men are emotionally controlled—a good fit with the social requirements of “manly behavior”.
“Even when a man is said to be a best friend,”Rubin writes,“the two share little about their innermost feelings. Whereas a woman's closest female friend might be the first to tell her to leave a failing marriage, it wasn't unusual to hear a man say he didn't know his friend's marriage was in serious trouble until he appeared one night asking if he could sleep on the sofa.”

New York, 10 November—5:27pm,yesterday. Biggest power failure in the city's
history.
 Thousands of people got stuck in lifts. Martin Saltzman spent three hours between the 21st and 22nd floors of the Empire State Building. “There were twelve of us. But no one panicked.

“It was the best night we've ever had,”said Angela Carraro,who runs an Italian restaurant on 42nd Street.“We had lots of candles on the tables and the waiters were carrying candles on their trays.

A characteristic of American culture that has become almost a tradition is to respect the self made man—the man who has risen to the top through his own efforts,usually beginning by working with his hands.While the leader in business or industry or the college professor occupies a higher social position and commands greater respect in the community than the common labourer or even the skilled factory worker,he may take pains to point out that his father started life in America as a farmer or labourer of some sort.
This attitude toward manual(体力的) labour is now still seen in many aspects of American life.One is invited to dinner at a home that is not only comfortably but even luxuriously(豪华地)furnished and in which there is every evidence of the fact that the family has been able to afford foreign travel,expensive hobbies,and college education for the children;yet the hostess probably will cook the dinner herself,will serve it herself and will wash dishes afterward,furthermore the dinner will not consist merely of something quickly and easily assembled from contents of various cans and a cake or a pie bought at the nearby bakery.On the contrary,the hostess usually takes pride in careful preparation of special dishes.A professional man may talk about washing the car,digging in his flowerbeds,painting the house.His wife may even help with these things,just as he often helps her with the dishwashing.The son who is away at college may wait on table and wash dishes for his living,or during the summer he may work with a construction gang on a highway in order to pay for his education.

Britain's oldest man made his first visit to London yesterday at the age of 110. Mr John Evans had never found the time or the money—to make the trip from his home near Swansea. But, when British Rail offered him an all expenses paid birthday trip to the capital, he just could not refuse.
Until yesterday he had never been far from home, except for one trip to Aberdeen. Mr Evans, who spent 60 years working as a miner in South Wales, almost made the journey to London once before, at the turn of the century.“There was a trip to the White City but it was ten shillings (1 shilling="1/20" pound) return from Swansea—too much I thought. All my money went to the family then,” he said.
During the next two days Mr Evans will be taken on a whistle stop tour of London to see the sights. Top of his list is a visit to the Houses of Parliament(国会).
The only arrangement he does not care for is the wheelchair provided to move
him about if he gets tired.“I don't like the chair business—people will so think I am getting old,” he said.
His secret for a long and healthy life has been well publicized—no alcohol, no cigarette and no anger. Before setting off from Swansea with his 76-year-old son, Amwel, he quipped, “I'm glad to see they've given me a return ticket.”
1.It was reported that Mr Evans's healthy long life was to a certain extent due to his________ .
A. wine drinking B. proper smoking
C. mild temper D. sense of humor
2.Which of the following statements is true?
A.A single trip from Mr Evans's home to the White City used to be ten shillings.
