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 |

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 |

There are many famous museums throughout the world where people can enjoy art, Washington, D.C. has the National Gallery of Art(美术馆); Paris has the Louvre; London, the British Museum. Florida International University(FIU) in Miami also shows art for people to see. And it does so without a building, or even a wall for its drawings and paintings.
FIU has opened what it says is the first computer art museum in the United States. You don't have to visit the University to see the art. You just need a computer linked to a telephone.
You can call the telephone number of a University computer and connect your own computer to it. All of the art is stored in the school computer. It is computer art, produced electronically (采用电子手段) by artists on their own computers. In only a few minutes, your computer can receive and copy all the pictures and drawings.、
Robert Shostak is director of the new computer museum. He says he started the museum because computer artists had no place to show their works.
A computer artist could only record his pictures electronically and send the records, or floppy discs(软盘), to others to see on their computers. He could also put his pictures on paper. But to print good pictures on paper, the computer artist needed an expensive laser(激光) printer.
Robert Shostak says the electronic museum is mostly for art or computer students at schools and universities. Many of the pictures in the museum are made by students. Mr Shostak said the FIU museum will make computer art more fun for computer artists because more people can see it. He says artists enjoy their work much more if they have an audience. And the great number of home computers in America could mean a huge audience for the electronic museum.The main purpose of this text is to give information about ______.
A. famous museums throughout the world.

While she may be best known for her role as Hermione Granger in the Harry Potter films,Emma Watson would rather be known for something else—her mind.

Watson,whose parents are both Oxford graduates,recently scored straight A's in her Alevels. She is now on a gap year before starting university.

“I think the entertainment business is such a temperamental one. One minute you're up there and the next—nothing,”she said.
Watson is growing up in front of millions of viewers(观众).She was only nine years old when she started playing the role of Hermione. And the way she figured out how to deal with media attention is “try not to read too much of what is said and try to distance myself a bit from it”.

Children brought up on healthy diets are more intelligent compared with their junk food eating partners, a new research suggests.
Kids fed a diet packed high in fats, sugars, and processed(加工) foods had lower IQs than those fed pasta(意大利面食), salads and fruit, it was found.
The effect is so great that researchers from the University of Bristol said those children with a "healthier" diet may get an IQ improvement.
Scientists stressed good diet was essential in a child's early life as the brain grows at its fastest rate during the first three years of life.
This indicated head growth at this time is linked to intellectual ability and “it is possible that good nutrition(营养) during this period may encourage excellent brain growth” .
Scientists tracked the long term health and happiness of around 14,000 children born in 1991 and 1992 as part of the West Country's Avon Longitudinal(纵向的)Study of Parents and Children( ALSPAC) .
Parents were questioned about the types and frequency of the food and drink their children consumed when they were three, four, seven and eight and a half years old. According to their different changing form, these children were marked and given grades which ranged from minus two for the most healthy to10 for the most unhealthy.
In the research, IQ was measured of 4,000 children when they were eight and half years old, using a validated(经过认证的)test-the Wechsler Intelligence Scale(韦氏儿童智力量表) for Children.
The results found after taking account of some influential factors, a leading processed food diet at the age of three was associated with a lower IQ at the age of eight and a half , whether the diet was improved after that age.
Every l point increase in dietary pattern score was associated with a l.67 fall in IQ.Scientists stressed good diet was essential in a child’s early life because.
A.the brain grows at its fastest rate during the first three years of life. |
B.those children with a "healthier" diet must get an IQ improvement. |
C.children brought up on healthy diets are less intelligent. |
D.these children were given good grades. |
Which of the following is NOT true?
A.Those children with a "healthier" diet may get an IQ improvement. |
B.Good nutrition at any stage may encourage excellent brain growth. |
C.Scientists tracked the long term health and happiness of about 14,000 children. |
D.Every l point increase in dietary pattern score was associated with a l.67 fall in IQ. |
The results found if a child ate a leading processed food diet when he was 3, he would.
A.have a higher IQ |
B.have a higher IQ as long as he improved his diet |
C.have one IQ when he was 8 |
D.have a lower IQ whether he improved his diet |
What is the best title of the passage?
A.Food for thought |
B.What is healthy food? |
