   No one is glad to hear that his body has to be cut open by a surgeon(外科醫(yī)生)and part of it taken out.Today,however,we needn’t worry about feeling pain during the operation.The sick person falls into a kind of sleep,and when he awakes, the operation is finished.But these happy conditions are fairly new.

   Long ago,operation usually had to be done while the sick man could feel everything.The sick man had to be held down on a table by force while the doctors did their best to save him.He could feel all the pain if his leg or arm was being cut off,and his fearful cries filled the room and the hearts of those who watched.

   Soon after 1770,Josept Priestley discovered a gas which is now called “l(fā)aughing gas”.Laughing gas became known in America.Young men and women went to parties to try it. Most of them spent their time laughing,but one man at a party,Horace Wells,noticed that people didn’t seem to feel pain when they were using this gas.He decided to make an experiment on himself.He asked a friend to help him.

   Wells took some of the gas,and his friend pulled out one of Wells’ teeth.Wells felt no pain at all.

   As he didn’t know enough about laughing gas,he gave a man less gas than he should have.The man cried out with pain when his tooth was being pulled out.

   Wells tried again,but this time he gave too much of the gas,and the man died.Wells never forgot this terrible event.

24. Long ago,when the sick man was operated on, he _________.

A.could feel nothing         B. could not want anything

C.could feel all the pain      D.could do anything

25. Using the laughing gas, the people did not seem to _________.

A.be afraid of anything        B.feel pain

C.want to go to the parties     D.be ill

26. If a man took less laughing gas than he should have when an operation went on, he _________.

A.felt nothing              B.felt very comfortable  

C.still felt pain             D.would die

27. One who took too much of the laughing gas _________.

A.would laugh all the time        B.would die

C.would never feel pain          D. would be very calm

    The world’s first plastic magnet (磁性) to work at room temperature has passed the elementary test of magnetism. Its creators at the University of Durham in the UK have used it to pick iron filings (鐵屑) from a laboratory bench.

    In 2001, chemists from the University of Nebraska-Lincoln claimed to have created the world’s first plastic magnet, but it only worked below 10 Kelvin (開氏溫度). Other researchers have made plastic magnets, but generally they only function at extremely low temperatures, or their magnetism at room temperature is too weak to be business use.

    So the Durham team can claim to have made the first plastic magnet that could be used in everyday products. One of the most likely applications is in the magnetic coating of computer hard discs, which could lead to a new generation of high-capacity discs.

    Jerry Torrance, a material scientist who is an adviser to some of the world’s largest electronics and engineering companies, including IBM, describes the work as “a great scientific breakthrough”. However, he says that practical applications are probably still a long way off.

    At first the new polymer (聚合物) showed little sign of magnetism, and after three months the researchers had reached the point where they felt that trying to induce (誘發(fā)) magnetism in this polymer was a waste of time. “Just as we were about to give up and try a different way, we decided to check the samples for a last time,” says Sean Giblin.

    It was a fortunate decision, because over the months the original polymer had developed magnetic characteristics. Further groups of polymer proved its magnetism and ruled out the possibility that the magnetism had been caused by pollution. In addition, X-ray diffraction data (衍射數(shù)據(jù)) showed an increase in the straight line of the polymer chains over three months, which probably accounts for the increase in magnetism.

    Although the polymer’s magnetism is weak compared with metal magnets, the researchers are confident that they can improve it. And in addition to computer hard discs, the team thinks that plastic magnets could have important medical applications because organic magnetic materials are less likely to be rejected by the body.

64. The plastic magnets made by the chemists from University of Nebraska-Lincoln and other researchers couldn’t be used in everyday products because        .

    A. they didn’t pass the elementary test of magnetism

    B. they couldn’t pick up iron filings from a laboratory bench

    C. they wouldn’t work at room temperature

    D. they could only be used at high temperature

65. The increase in magnetism over the months is probably caused by        .

    A. checking the samples             B. a wise decision

    C. pollution

    D. the increase in the straight line of the polymer chains

66. The plastic magnets could be used        .

    A. to compare with the metal magnets

    B. to coat computer hard discs

    C. to produce medicine

    D. to lower the temperature

67. What would be the best title for the passage?

    A. The Birth of Practical Plastic Magnet

    B. The World’s First Plastic Magnet

    C. A Fortunate Decision

    D. The Applications of Plastic Magnets

D  

Every August on the island of Heimaey, young people often take a walk along the street throughout the night. Why their parents allow them to stay out ? The children of Heimaey are going to save young puffins ---- small black-and-white seabirds.

The cliffs(懸崖)above the town are home to a large group of puffins . The birds dig holes all around the cliffs . These holes are their homes. The young stay in the holes for about seven weeks. Then they begin to leave . Some move slowly on their undeveloped wings and feet down to the sea around Heimaey. There they swim, which they can do naturally , and learn to dive for fish . Others, however, may lose their way at night and find themselves in the town instead. On the ground, the young birds are in trouble. Because their wings are fully developed, they cannot take off quickly to sea and safety. The birds then become a good meal for cats and other animals .

For many years, islanders have help the young puffins. At night in late August, children carrying thick paper boxes and lights hurry out to catch puffins . They spend most of the night running after the birds. They put the birds they've caught into boxes and take good care of them .

The next morning the children take the puffins to the sea and set them free. The bird will live at sea until they are at least two years old. Then they will return to the cliffs to build homes of their own.

The children of Heimaey look forward to August !

A.they enjoy playing the game of running after seabirds

20.According to the passage, which of the following is NOT TRUE?   

A.Once a year the children are allowed to stay out at night to have a good time .
