The surprising experiment I am about to describe proves that air is all around you and that it presses down upon you. Air pressure is a powerful force. When you swim underwater, you can feel water pushing down on 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 for 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
Method
1） Check that the egg 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! This proves that air is all around and that it is pressing down on it. 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. |
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 |
How did the egg put into the bottle？
| A．The oxygen inside the bottle sucked the egg in. |
| B．It became saft without the shell. |
| C．The neck of the bottle was wide enough. |
| D．The outside air pressure forced it into the bottle. |
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 they could for help, hoping that Mrs. Tailor would not wake and turn the girls into frogs. . Why were the children hiding in the tree?
| A．They wanted to watch Mrs. Tailor do her housework closely. |
| 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 |
. Mrs. Tailor stopped sweeping when____
| A．her front steps were clean | B．she noticed the children in the tree |
| C．she was ready to take a flight | D．she heard the hen cackling |
. Ben did not rush in help Mrs. Tailor because_____
| A．he thought that she could be tricking them |
| B．he knew that they could not have been in the tree |
| C．he did not see the old lady fall down |
| D．he was afraid of the three-legged cat |
. Which of these old sayings best suits the story’s lesson for us?
| A．Make hay while the sun shines. |
| B．Never judge a book by its cover. |
| C．People in glasshouses should not throw stones. |
| D．A bird in the hands worth two in the bush. |

Most of us are used to seasons. Each year, spring follows winter, which follows autumn, which follows summer, which follows spring. And winter is colder than summer. But the earth goes through temperature cycles over much longer periods than those that we experience.
Between 65,000 and 35,000 years ago, the planet was much colder than it is now. During that time the temperature also changed a lot, with periods of warming and cooling. Ice melted during the warm periods, which made sea levels rise. Water froze again during the cold periods.
A new study from Switzerland sheds light on where ice sheets melted during the ice age.
It now seems that the ice melted at both ends of the earth, rather than just in either northern or southern areas. This surprised the researchers from the University of Bern.
Scientists have long assumed(认为) that most of the ice that melted was in the Northern hemisphere(半球) during the 30,000-year-long ice age. That belief was held because the North Pole is surrounded by land, while the South Pole is surrounded by the Antarctic Ocean. It is easier for ice sheets to grow on land. If surrounded by sea, the ice can easily just slip to the ocean instead of building up.
The researchers used a computer model to look at the ways the ice could melt and how it might affect sea levels. They compared these results to evidence(迹象) of how temperatures and currents actually changed during that time.
The model showed that if it was only in the Northern hemisphere that ice melted, there would be a bigger effect on ocean currents(洋流) and sea temperatures than what actually happened. Studies suggest that melting just in the Southern hemisphere would have been impossible, too.
The only reasonable conclusion, the scientists could make, was that the ice melted equally in the North and the South.
It is still a mystery(谜) as to what caused the temperature changes that caused the ice to melt.

In the 1960s, people asked about your astrological sign(星相). In the 1990s, they wanted to know your website (网址). These days, having a web address is almost as important as a street address. Your website is an electronic meeting place for your family, friends and potentially, millions of people around the world. Best of all, you may not have to spend a cent. The Web is filled with all kinds of free services and all it takes is some time and creativity.
Think of your home page as the starting point of your website. Like the table of contents of a book or a magazine, the home page is the front door. Your site can have one or more pages, depending on how you design it.
While web pages vary greatly in their design and content, most use a traditional magazine layout (版面设计). At the top of the page is a banner(大标题) GRAPHIC. Next comes a greeting and a short description of the site. Pictures, texts, and links to other websites follow.
Before you start building your site, do some planning. Think about whom the site is for and what you want to say. Next, gather up the material that you want to put on the site. Draw a rough layout on a sheet of paper.
While there are no rules you have to follow, there are a few things to keep in mind:
Start simply If you are too ambitious (雄心勃勃的) at the beginning, you may never get the site off the ground. You can always add to your site.
Less is better Most people don't like to read a lot of text online. Break it into small pieces.
Smaller is better Most people connect to the Internet with a modem (调制解调器). Since it can take a long time to download large image files, keep the file sizes small.
Have the rights Don't put any material on your site unless you are sure you can do it legally (合法地). Learn the Net's Copyright Article for more about this.
Now it's time to roll up your sleeves and start building. Learning the Net Communities provides tools to help you build your site.

No one can believe that the over 6,300-kilometer Great Wall might disappear some day. Believe it or not, the Great Wall is being destroyed by people. Less than 20 percent of the Great Wall built in the Ming Dynasty, is still perfect, but about 80 percent is in danger. The Great Wall can be called "great" mostly because of its amazing length. But we should realize that the length was made up of one brick at a time. If we do nothing to save the Great Wall, it will become a series of separate wasteland rather than a historic site.
The Great Wall is actually a series of walls built and rebuilt by different dynasties over the past 2,000 years. It began in the rule of China's first emperor, Qin Shihuang of the Qin Dynasty(221 BC-206 BC), and lasted into the Ming Dynasty. The parts built before the Ming Dynasty have nearly disappeared. People are familiar with sections such as Badaling in Beijing and Jiayuguan Pass in Gansu, because they have been open to tourists for many years. But those sections far away from the public eyes have been almost forgotten.
Few local people knew the 3-metre-high walls made of earth and stones beside them are part of the Great Wall. The lack of knowledge is considered as one of the main reasons behind human.
The bricks on the Great Wall are carried off by countryside people to build their houses, sheep corrals and pigsties. Some were taken away to build roads. Bricks carved with people's names are put away as remembrances. Rubbish is spread over the battlements. The bricks can be sold for 15 yuan per tractor load. Those who destroyed and are destroying the Wall know its name, but are not clear about its cultural meaning. It will take a long time to let them know this. The local farmers not only carried off the body of the Wall but also dug out the entire base.
It is necessary to protect the Great Wall. First of all, the officials should be aware of the importance of the Great Wall. Young Chinese should know more about the nation's great civilization and learn to love it.
64. Why does the writer say the Great Wall might disappear?
A. It is useless from now on.
B. It will be replaced by a new one.
C. Some parts of it are being destroyed.
D. It is too old to be used again.
65. According to the passage, which of the following is TRUE?
A. The Great Wall was completed in the Ming Dynasty.
B. Not all the foreign tourists like the Great Wall.
C. The first part of the Great Wall was built in 221 BC.
D. The Qin Great Wall was protected well.
66. The underlined part "those sections far away from the public eyes" (in Paragraph 2) refers to the parts of the Great Wall _____.
A. that are too difficult to find
B. nobody can watch
C. that are too far to be seen
D. that are not well-known to the public
67. What's the main reason of the Great Wall's being destroyed?
A. The local people are short of culture knowledge.
B. The local people need bricks and stones to build houses.
C. The local people think that the Great Wall is not important.
D. The local people sell the bricks for a living.
