The surprising experiment I am about to describe proves that air is all around you and that it proves down upon you. Air pressure is a wonderful force. When you swim underwater, you can feel water push down your body. The air all around you does the same. However, your body is so used to it that you do not notice this. The pressure is caused by a layer of air called the atmosphere. This layer surrounds the Earth, extending to about five kilometers above the Earth’s surface.

The following experiment is an easy one that you can do at home. But make sure that you are supervised, because you will need to use matches. Now foe the experiment!

What you need

·A hard-boiled egg without the shell

·A bottle with a neck slightly smaller than the egg

·A piece of paper

·A match

Metheod

1) Check that the paper will sit firmly on the neck of the bottle.

2) Tear the paper into strips and put the strips into the bottle.

3) Light the paper by dropping a burning match into the bottle.

4) Quickly sit the egg on the neck of the bottle.

Result

Astonishingly, the egg will be sucked into the bottle. Your friends will be amazed when you show them the experiment. But be careful when you handle matches.

Why it happened

As the paper burns, it needs oxygen and uses up the oxygen (air) in the bottle. The egg acts as a seal in the neck of the bottle, so no more air can get inside. This reduces the air pressure inside the bottle. The air pressure must equalize, so more air from outside must enter the bottle. The outside air pressure against the egg and then the egg is pushed into the bottle! The proves that air is all around and that it is pressing down on it.

60. Why is there the need to take care when you are doing the experiment?

A. The bottle could break.

B. You need to light the paper with a match.

C. The egg needs to be shelled.

D. The egg has to be perfectly placed on the neck of the bottle.

61. In the experiment, the burning inside the bottle can___.

A. equalize the air pressure inside and outside

B. make a seal in the neck of the bottle

C. finish up the oxygen inside the bottle

D. produce more oxygen inside the bottle

62. How did the egg put into the bottle?

A. The oxygen inside the bottle sucked the egg in.

B. It became salt without the shell.

C. The neck of the bottle was wide enough.

D. The outside air pressure forced it into the bottle.

63. The experiment is carried cut to prove ______.

A. water pushes on your body when you swim underwater.

B. the earth is surrounded by a layer of air called the atmosphere.

C. the pressure of air around us has a powerful force.

D. the air pressure is not equalized around us.

Outside her shabby cottage, old Mrs. Tailor was hanging out laundry on a wire line, unaware that some children lay hidden in the leaves of a nearby tree watching her every move. They were determined to find out if she really was a witch.

They watched as she took a broomstick to clean the dirt from her stone steps. But, much to their disappointment, she did not mount the broomstick and take flight. Suddenly, the old lady’s work was interrupted by the cackling of her hen—a signal that an egg had been laid in the warm nest on top of the haystack.

The old broomstick was put aside as she hobbled off towards the haystack followed by Sooty, a black cat she had rescued from a fox trap some time back. With only three legs, it was hard for Sooty to keep up with the old lady. The cat provided proof—the children were sure that only a witch could own a black cat with three legs.

There, standing on a wooden box, was Mrs. Tailor, stretching out to gather her precious egg. Taking the egg in one of her hands, she began to climb down when, without warning, the box broke and the old lady fell.

 “We have to got and help her,” whispered Amy.

 “What if it is a trick?” replied Ben.

 “Don’t be silly, Ben. If she were a witch, she would have turned us into frogs already,” reasoned Meg. “Come on Amy, let’s go.” The girls climbed down the tree and ran all the way to the haystack.

Approaching carefully, they could see a wound on the old lady’s face. She had knocked her head on a stone and her ankle was definitely broken. “Go and get Dad,” Amy yelled to her brother. “Tell him about the accident.”

The boys did not need another excuse to leave. They ran as fast as thy could for help, hoping that Mrs. Tailor would not wake and turn the girls into frogs.

56. Were the children hiding in the tree?

B. They were playing a hide-and-seek game

C. They wanted to find out if the rumors about Mrs. Tailor were true

D. They were pretending to be spies

57. Mrs. Tailor stopped sweeping when____

D. she heard the hen cackling

A. he thought that she could be necking them

B. he knew that they could not have been in the tree

C. he did not the old lady fall down

D. he was afraid of the three-legged cat

59. Which of these old sayings best suits the story’s lesson for us?

Many people to newspaper and magazines to express their opinions. Letters to the editor must carry the writer full name, address and telephone number, although the information is not necessary for publication. This requirement to provide personal particulars is a clear indication that writers are held responsible for what they say. When a writer wants his voice heard. He needs to claim ownership of his voice. Responsibility is the name of the game.

 “People today prefer living together to putting their signatures on a marriage certificate because they refuse to accept responsibility for the relationship,” said social worker Ken Yip, “and this is what is causing a lot of family problems.” When we sign a paper, for example, a business contract or a bank document, the signature is symbol of consent, an agreement to take the matter seriously. Most governments and many organizations will not process writer’s complaints if they do not bear the writer’s signature. The absence of a signature, they explain, tells us that the writer cannot be too serious and therefore does not deserve a reply.

There are people who wish to remain anonymous(匿名的)for various reasons. Multi-billionaire Mr. King donates generously to charity several times a year. He gives simply because he wants to help but not for the publicity his donations may bring, and he does not want his good deeds to make news. In other cases, people insist on anonymity because they are afraid of the consequences of revealing their identity. Crime witnesses may be willing to assist the police, but most are unwilling to give their names when reporting a crime.

Name or no name? The answer is very personal and lies in how much we want to get involved. We all have a name, it is a matter if responsibility to it when we make a statement, a claim or an accusation. We all want to honour our own name, and it is only by stamping our expression of an opinion with our own name that we honour what we say.

68. What does the writer mean by saying “Responsibility is the name of the game”?

A. Writers need to provide their personal information in the game.

B. Publication must bear the writer’s full name, address and phone number.

C. Writers should be responsible for their names.

D. Names are required to indicate writers’ responsibility for what they say.

69. The second paragraph suggests that a paper without a signature may       .

A. help to end a relationship

B. not get a reply

C. be accepted all the same

D. become a family problem

70. Some people don’t want their names known because they are         .

A. hesitant to make a donation         B. unwilling to draw public attention

C. afraid of an accusation             D. ready for involvement

71. The passage is mainly about           .

A. honour and writers                  B. identity and signature

C. signature and responsibility        D. anonymity and signature

New archaeological discovers suggest that trade between Europe and Asia along the Silk Road probably began in some form many countries earlier than once thought. The findings, coupled with a widening range of scientific and historical research could add a fascinating new page to the epic of the Silk Road.

The farest and most surprising discovery is pieces of silk found in the hair of and Egyptian mummy from about 1000 BC, long before regular traffic on the Silk Road and at least one thousand years before silk was previously thought to be used in Egypt. Other research may extend human activity along this route back even further, perhaps a million years to the migration of human ancestors into eastern Asia.

The official origin of East-West commerce along the road is usually placed in the late 2nd century BC which was the agent of the Chinese Emperor Wu-di returned from a dangerous secret mission(使命)across the desert into the remote high country of Central Asia. The agent, Zhang Qian, travelled as far as Afghanistan back knowledge of even more distant lands such as Persia, Syria and a place known as Lijion,. Histerents have called this one of the most important journeys in ancient times. His journey opened the way for what have been thought to be the first indirect contacts between the ancient world’s two superpowers, China and Rome. Chinese silk, first traded to central Asian tribes for war horses and to the Parthians of old Pet la lu exchange for acrobats and ostrich eggs, was soon finding its way through a network of merchants to the luxury markets in Rome.

But the new discoveries show that Chinese silk was apparently present in the West long before the Han emperor started organized trade over the Silk Road. The research could change thinking about the early history of world trade and provide insights into the mystery of just how and when Europe and the Mediterranean lands first became aware of the glorious culture at the other end of Eurasia.

72. The word “coupled” in the first paragraph could best be replaced by         .

A. produced       B. contributed      C. doubled        D. combined

73. The silk thread found in the hair of an Egyptian mummy suggests that          .

A. Egyptians had probably travelled to China to buy silk

B. trade along the Silk Road began earlier than once thought

C. historical research often achieves fascinating results

D. new light can now be thrown on ancient trading practices

74. Until recently most historians believed that trade along the Silk Road        .

A. originated in the 2nd century BC

B. extended human migration into eastern Asia

C. began a million years ago

D. primarily benefited the Egyptians

75. Historians have always considered Zhang Qian’s mission important because they believe            .

A. be brought back knowledge of Rome to the emperor

B. be discovered the Silk Road

C. be helped establish East-West trade

D. be travelled as far as Afghanistan
