阅读下列应用文及相关信息,并按照要求匹配信息。首先,请阅读以下世界古代奇观的简介:

A. The Great Wall was begun more than two thousand years ago. It was built to keep out invaders. It extends about six thousand seven hundred kilometers across northern China. Today, the Chinese government is working to repair parts of the wall and protect as much of it as possible. The Great Wall of China is one of the largest building projects ever attempted. It is also the only object built by people that can be seen from space.

B. The Coliseum in Rome, Italy was built almost two thousand years ago. The ancient Roman sports center could hold fifty thousand people who gathered there to watch public events. Experts say it is one of the finest examples of Roman design and engineering.

C. The city of Machu Picchu in Peru includes some of the best stone work ever built. The ancient Inca people built Machu Picchu high in the Andes Mountains, northwest of the city of Cuzco. Machu Picchu is about thirteen square kilometers. Historians say it might have been one of the last places of safety for the Incas who were fleeing invaders from Spain.

D. India is famous for its temples and buildings. The most famous is the Taj Mahal, considered one of the most beautiful buildings ever built. The fifth Mughal emperor, Shah Jahan, ordered it built in Agra in sixteen thirty-one. He built it as a burial place in memory of his wife. The Taj Mahal has tiny colorful stones inlaid in white marble. The structure seems to change color during different times of the day and night.

E. Abu Simbel was built more than three thousand years ago. It is about 280 kilometers south of Aswan on the western bank of the Nile River. It took an army of workmen and artists more than thirty years to cut the huge temple into the face of a rock mountain. In front of the main temple are four huge statues of Ramses the Second. Each statue is about twenty meters high.

F. Stonehenge also belongs on a list of ancient wonders. It is a circle of huge stones in southeastern England. Experts believe work began on Stonehenge about five thousand years ago. We know very little about Stonehenge. We do not even know how these huge stones were moved to the area. Much has been written about Stonehenge, but experts say they still are not sure what it was used for.

以下是旅行者信息,请匹配他们计划参观的世界奇观。

Mr. Smith, who comes from Rome, Italy, plans to visit Asia. He hears about a beautiful building which tells a moving story about the love between an ancient ruler and his wife.

Li Hua, who has been to the Great Wall several times, plans to visit an ancient wonder in Europe which has as long a history as the Great Wall.

Cindy, who comes from India, plans to visit an ancient temple on the bank of a famous river in Africa. The temple, in front of which there were some huge statues, is one of the greatest stone works ever built.

Jack will visit one of the oldest stone work ever built by people. It was made up of huge stones, but how ancient people moved the stones and why they built it remain a mystery.

A scientist will be sent into space. He hopes he can see an object built by human beings when he looks at our earth with his bare eyes.

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 “________”.

A. health     B. long life   C. ageing    D. effect

The text mainly talks about ________.

A. men’s heart cells

B. women’s ageing process、

C. the gender difference

D. hearts and long life

According to the text, the UK scientists have known that ________.

A. women have more cells than men when they are born

B. women can replace the cells that enable the heart to beat

C. the female heart loses few of the cells with age

D. women never lose their pumping power with age

If you want to live longer, you should ________.

A. enable your heart to beat much faster

B. find out the reason for ageing

C. exercise regularly to keep your heart healthy

D. prevent your cells from being lost

We can know from the passage that ________.

A. the reason why ageing takes a greater loss on the male heart has been found out

B. scientists are on the way to finding out why the male heart loses more of the cells

C. the team has done something to prevent the male from suffering the greater loss

D. women over 70 could lose more heart cells than those at the age of 20

Three high students become heroes after their act of saving a baby’s life.

Andrew Willis, 15, his brother Chris, 13, and friend Reece Galea, 14, were walking along Swallow Drive on their way to school on May 23, when Nicholle Price ran out of her house, shouting for help. Her six-month-old son Corey had swallowed (吞下) an earring (耳环) and the young mother couldn’t ring for help because something was wrong with her phone. The three teenagers rushed to the aid of Ms Price, called an ambulance (救护车), calmed her down and waited with her until the ambulance arrived before heading to school.

Ms Price, Corey and his grandmother Joyce Finnie visited the school last Thursday to thank the boys for their kind action. “It’s good to know that there are still some good people who will stop and help,” Ms Price said. “While I was shouting for help, a woman walking her dog went straight past, without stopping. I don’t know what would have happened if these boys had not stopped.”

The teenagers were shocked at the attention they received at school for their heroic act but admitted that the incident was nerve-racking(刺激神经的). “We heard her shouting so we knew something wasn’t right,” Andrew said. “We thought someone had died. It was scary (惊慌的) but we just did what we had to do.”

Just as proud as the boys’ parents is their principal, Tim McCallum.

After two days in hospital, Corey has now fully recovered. “He’s got two new teeth to show,” Ms Price said. “I have to keep a closer eye on him. He’s into everything now and grabs whatever he finds to put it straight into his mouth.”

1.The three high students were _____ when a woman ran out of her house shouting for help.

A.playing near the house

B.on their way to school

C.walking their dogs nearby

D.on their way back from school

2.Ms Price spoke of a woman walking her dog without stopping to show _____.

A.how dangerous the case was

B.how brave the three boys were

C.why the three teenagers’ action was heroic

D.how clever the three boys were

3.The underlined sentence in the 4th paragraph probably means “_____”.

A.they didn’t expect they would be given so much praise

B.they felt excited to have become so famous after the incident

C.they were supposed to receive so many prizes for their good deed

D.they were proud of the attention they received at school for their heroic deed

4. Which would be the best title for this passage?

A.How a baby was saved after swallowing an earring

B.Why the mother shouted for help

C.Baby life saved: teenage heroes earn high praise

D.A mother came to school to thank 3 teenagers

    The use of the word imitation(模仿) reminds me that we ought to make some more comments on the risk of people imitating what they see on the screen in the way of crime(犯罪) or violence.First there was always a risk of children acting out scenes which could be dangerous.For example,I remember a woman who was head of a middle school telling me that she had happened to look out of her window when the children were on the playground and had seen them putting a small boy on a chair with a rope round his neck and the rope over the branch of a tree;fortunately she was in time to get there before the child was hanged.I remember a film in particular in which the hero who was imprisoned had escaped by electrocuting(通电触死) his guard,the technique of doing this being shown in detail.This was the kind of scene which we could cut for these reasons.

    In films for young people and adults we always tried to keep off the screen the details of criminal techniques,such as how to open a locked door with a piece of hard plastic or how to open a safe;if we were consulted(请教) before production,I used to advise that the details should not be shown.When I gave talks in prisons about film checking I had full support for this,since fathers who were in prison for criminal offences did not want their children to get on crime.

    Every time I gave a talk in a prison someone used to mention the French film Rififi.made by Jules Dassin in 1954.This remarkable film showed in great detail a robbery of a jeweller’s shop,the robbery lasting about half an hour and being backed by only natural sound...one of the most brilliant film sequences(连续镜头) of all time.I remember our discussion at the time.We thought that the robbery was finished only with the use of advanced and obviously expensive equipment and that only the most experienced and skilled criminals could possibly imitate it;we believed therefore that it was relatively safe.When talking in prisons some years later I learned that there had been several robberies in which the techniques had been copied,so perhaps we were wrong.

1.The writer thinks that______.

    A.the details of the criminal technique should be kept

    B.the details of the crime should not be shown on the screen

    C.children should not imitate what they see on the screen

    D.it is dangerous to imitate what they see on the screen

2.What is the writer’s attitude(态度) towards the film in which the hero had escaped by electrocuting the guard?

    A.The writer likes it very much.                   

    B.The writer is strongly against it.

    C.The writer thinks the film has some value.       

    D.The writer does not show his/her attitude.

3.All the following statements about“Rififi”are true EXCEPT______.

    A.that the robbery shown needs experience and skills

    B.that some very good tools were used in the robbery

    C.that the film showed the technique in detail

    D.that the technique of the robbery was not imitated

4.It can be inferred from the passage that______.

    A.it is hard for children to tell the differences between real life and the imaginary

    B.only people in prison support film checking

    C.only children imitate what they have seen on the screen

    D.the writer used to advise the details of crime should be shown
