Why do men die earlier than women? The latest research makes it known that the reason could be that men’s hearts go into rapid decline when they reach middle age.
The largest study of the effects of ageing on the heart has found that women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age.
“We have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK. “Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men,” said Goldspink. “This is part of the ageing process.”
What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s.
“This gender difference might just explain why women live longer than men,” said Goldspink. They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease.
“The team has yet to find why ageing takes a greater loss on the male heart,” said Goldspink. The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.The underlined word “longevity” in the second paragraph probably refers to “________”.

In many homes, divorce is caused by the “battle between the sexes.” To understand the problem, one must remember that the modern American woman is freed. During childhood and adolescence(青少年期), the American girl is given freedom and education which is equal to a boy's. After completing school, she is able to get a job and support herself. She doesn't have to marry for financial security. She considers herself an independent, self-sufficient person. She wants a husband whom she can respect, but she doesn't want to be dominated(控制) by him. She wants a democratic household in which she has a voice in making decisions. When a husband and wife are able to share decisionmaking, their marriage is probably closer, stronger, and more satisfying. Otherwise, the couple is likely to wind up in the divorce court.
When a couple gets divorced, the court usually requires the man to pay his former wife a monthly sum of money. If the couple has children, they usually remain with the mother, and the father is expected to pay for their support.
Although divorce is quite common in the United States, 80 percent of those who get divorced remarry. The remarriages allow thousands of people, especially children, to enjoy family life again, but at the same time many troubles have arisen. A well-known American joke tells of a wife calling to her second husband, “Quick, John! Come here and help me! Your children are beating up our chidlren!”What causes most of the divorce cases in the U.S.A.?
A.Financial trouble in the family.
B.Women's liberation movement.
C.Different attitudes towards children's education.

D.They respect their husbands, but do not rely on them. |
What kind of marriage can be successful?
A.Both the man and woman are financially secure. |
B.Husband and wife share housework. |
C.Both the man and woman are well-educated. |
D.Decisions are made by the man and woman together. |
What happens when a couple is divorced, according to the passage?

There is a story of a country where the rate of inflation(通货膨胀) is so high that clever people pay for a taxi ride before, instead of after the trip. The story may not be true, but inflation was almost that serious in Germany from July 1920 until December 1923. Prices went up so fast that by the end of 1923 they were 50 billion percent higher-arise of almost 2,500% a month.
There was so much paper money, and it had so little value, that people carried bags full of money around to pay for things. One woman tells the story of standing outside a shop with a basket full of 500,000 marks(马克) notes. She wanted to buy just one piece of meat, and she hoped she had enough money. But when she was looking, a thief robbed her. He didn't take her money, he threw it away and took the basket instead.
At first workers demanded to be paid every day, but as the situation became worse, they had to be paid twice a day. But they had to run out and spend the money at once, or it would lose its value. People bought anything that was for sale, but food was almost impossible to find. Farm workers refused to take money. They wanted to be paid in potatoes instead.
New policies ended the inflation in 1923, when the government introduced a new money, but about half of the German people lost everything in those three and a half years.According to the text, in Germany the prices in 1920 were ______.
A.the lowest in history | B.the highest in history |
C.higher than those in 1923 | D.lower than those in 1923 |
The thief stole the basket instead of the money in it because he thought ______.

B.the money was of no value |
C.the basket was more valuable than the money |
D.he couldn't buy a piece of meat with the money |
The farm workers demanded to be paid in potatoes because they believed ______.
A.the potato was valuable | B.the money might lose its value |
C.the potato was too expensive | D.the money could not buy potatoes |
Computer people talk a lot about the need for other people to become “computer-literate”. But not all experts agree that this is a good idea.
One pioneer, in particular, who disagrees is David Tebbutt, the founder of Computertown UK. Although many people see this as a successful attempt to bring people closer to the computer, David does not see it that way. He says that Computertown UK was formed for just the opposite reason, to bring computers to people and make them “people-literate”.
David Tebbutt thinks Computertowns are most successful when tied to a computer club but he insists there is an important difference between the two. The clubs are for people who have some computer knowledge already. This frightens away non-experts, who are happier going to Computertowns where there are computers for them to experiment on, with experts to encourage them and answer any questions they have. They are not told what to do. They find out. The computer experts have to learn not to tell people about computers, but have to be able to answer all questions people ask. People don't have to learn computer terms(术语), but the experts have to explain in plain language. The computers are becoming “people-literate”.Which of the following is David Tebbutt's idea on the relationship between people and
computers?
A.Computer learning should be made easier. |
B.There should be more computer clubs for experts. |
C.People should work harder to master computer use. |
D.Computers should be made cheaper so that people can afford them. |
We can infer from the text that “computer-literate” means ______.
A.being able to afford a computer |
B.being able to write computer programs |
C.working with the computer and finding out the value |
D.understanding the computer and knowing how to use it |
The underlined word “it” in the second paragraph refers to the idea that Computertowns ___.
A.help to set up more computer clubs | B.bring people to learn to use computers |
C.bring more experts to work together | D.help to sell computers to the public |
David Tebbutt started Computertown UK with the purpose of ______.
A.making better use of computer experts | B.improving computer programs |
C.increasing computer sales | D.popularising computers |
Watercolor is the oldest paints known. It dates back to the early cave men who discovered they could add lifelike qualities to drawings of animals and other figures on the walls of caves by mixing the natural colors found in the earth with water.
Fresco(壁画), one of the greatest of all art forms, is done with watercolor. It is created by mixing paints and water and applying these to wet plaster(灰泥). Of the thousands of people who stand under Michelangelo's heroic ceiling in the Sistine Chapel, very few know that they are looking at perhaps the greatest watercolor painting in the world.
The invention of oil painting by the Flemish masters in the fifteenth century made fresco painting go down-hill, and for the next several centuries watercolor was used mainly for doing sketches(素描) or as a tool for study. It was not until the eighteenth and nineteenth centuries that English painters put back watercolor as a serious art form. The English have a widely-known love for the outdoors and also small, private pictures. The softness of watercolor had a remarkably strong attraction for them.
The popularity of watercolor continued to grow until in the twentieth century. The United States passed England as the center for watercolor, producing such well-known watercolor artists as Thomas Eakins and Andrew Wyeth.What is the passage mainly about?
A.The gradual weakness of fresco painting. |
B.Oils having more power or influence over watercolor. |
C.The rediscovery of watercolor in England. |
D.The start and development of watercolor. |
The first watercolor artists were ______.
A.early cave men | B.Italian fresco artists |
C.Flemish masters | D.English artists of the 18th century |
In 16th and 17th centuries the artists thought ______.
A.watercolor was more costly, but was better |
B.oil painting lasted less long, but clearer and brighter |
C.watercolor was not suitable for finished works |
D.oil painting was difficult to use |
According to the passage, watercolor painting was put back in England because ______.
A.it was easy to use outdoors B.it was a strong medium
B.it was extremely bright in color D.it was well suited to popular tastesWhat would the next paragraph most probably deal with?
A.The works of famous American watercolor artists. |
B.The weakness of oils as popular paints. |

“BANG!” the door caused a reverberation(回声).It was just standing there, with father standing on one side , and I on the other side.
We were both in great anger” Never set foot in this house again!” stormed father.With tears welling up in my eyes, I rushed out of the flat and ran along the street.
The street lights were shining rather desolately(凄凉的).I wandered aimlessly.
A young father who held a child in his arms walked past me.I felt as if I saw my childhood from another space: happy and harmonious.
But now...I don’t know whether it is because I have grown up or because dad is getting old.We differ in our ways of thinking.He always imposes his opinions and codes of behavior on me.Whenever I do something wrong, he never admits it.We are just like two people coming from two different worlds.It feels like there is an iron door between us that can never be opened.
I wandered the streets, without a destination in mind.My heart was frozen on this hot summer night.As I walked on there were fewer and fewer people on the streets, until I had only the street lights to keep me company.When I finally reached the high-rise apartment block in which I lived ,I saw that the light was still on.
I thought to myself: “Is father waiting for me, or is he still angry with me?”
In fact, it was nothing.Perhaps, dad was throwing away some of his old stamps.Perhaps he thought they were useless.I never had the courage to tell him that I liked collecting stamps.I can’t stand his outrageous(蛮横的)words: “I can’t throw you away, let alone these old papers ?”
All the lights were off except father’s.
Dad was always like this.Maybe he didn’t know how to express himself.After shouting at me, he never showed any mercy or any moments of regret.After an argument he has the habit of creeping up in my sleep and then tucking me underneath the covers.
This was how he always was.He has been a leader for so long that telling everyone else what to do has become his second nature.
The light was still on.“Am I wrong?” I whispered ,maybe...With the key in hand, I was as nervous as I had ever been.At last, I decided to open the door.As soon as I opened the door tears ran down my cheeks.I suddenly realized that the iron door that I had imagined between us did not exist at all.Love—it second to none.Decide which is the best order of the following according to what happened in the passage.
a.I opened the door and entered the house.
b.Sadly I ran out into the street.
c.I reached the place where I lived and saw my house still brightly lit.
d.I thought of my father’s kindness towards me.
e.I walked about in the street without any aim.
A.b,e,d,c,a | B.b,e,c,d,a | C.b,e,a,c,d | D.b,e,c,a,d |

A.The sight of the desolate street lights. |
B.The sight of the empty street. |
C.The sight of a father with a child in his arms. |

A.perhaps the father is getting older and older. |
B.perhaps the son has already grown up. |
