JIUQUAN, Gansu Province, Sept. 6(Xinhua) ---- China’s manned spacecraft Shenzhou-7 will be launched at an appropriate time between Sept. 25 and 30 from the Jiuquan Satellite Launch Center in northwestern Gansu Province, a spokesman said here on Saturday. The mission will accomplish the first spacewalk by Chinese astronauts.
“All the major systems involved in the launching are now in the final preparation. The main tests for the spacecraft, the Long-March II-F rocket, suits for the space walk and a satellite accompanying the fly have also been finished, ” said the spokesman.
In addition, the ground control system is fully prepared, including the launch site, the landing site, and the communication for observation and control.
When Shenzhou-7 enters its orbit, one of the three taikonauts will conduct a space walk, said Zhao Changxi, a senior scientist with the project, earlier.
According to Zhao, cameras would be fixed outside and inside of the ship for live broadcasting of the space walk.
While the last mission of Shenzhou-6, with a crew of two, was aimed at several days of manned flight, this time the task might be more stringent as one of its main goals is the space walk.
Earlier reports said a crew of six astronauts had been chosen for the mission, with three manning the spacecraft and three substitutes.
China successfully put two manned spacecrafts into orbit in 2003 and 2005 respectively, becoming the third country to send an astronaut into space after the United States and the former Soviet Union(now Russia).What is the main idea of the passage?
| A．Shenzhou 7 is better equipped than the last two spaceships. |
| B．Shenzhou 7 will be more successful than the last two launches. |
| C．All the systems involved in the launching have been prepared. |
| D．China is ready for the launching of SHenzhou 7. |
We can learn from the passage_____________.
| A．This will be the third time for Chinese astronauts to have a space walk. |
| B．Three of the six astronauts chosen for the mission will walk in space |
| C．The space walk will be live broadcast on TV |
| D．Everything has been prepared except communication system |
I HEAR America beeping(嘟嘟响)．
Beep，says my cellophane when it gets a text message．
Beep，says my microwave oven when my sandwich is warmed up．
Sometimes I long for a natural sound：a bird singing，dog barking，children laughing， anything to drown out the maddening beeps that have become the soundtrack(配乐)to modern life．
My cellophane? It isn’t enough that its ring tone offerings seem to stretch from “annoymg” toextremely “annoying”． It also has to beep whenever someone texts messages me．
The microwave? A bell rings when it's finished heating my food．But is that enough? No．If I don’t rush to it right away, it starts beeping，like an impatient child tugging(用力拉) at my sleeve(袖子)．
The smoke detector(探测器) is the worst offender．When its batteries are in need of replacement，it 1ets out a series of chirps．The things that don’t beep buzz(嗡嗡响)．And for some reason，beeping and buzzing is beneath them，they clear their throats and perform a symphony． Like my TV, each time I turn it on, it performs an aria(咏叹调)：La di da di dum．Salutions! Here I am! Same thing when I turn it off: La di da di dum．Good bye, kind sir! Until the next time
But at 1east I know where each of these sounds is coming from．That isn’t always the case．For weeks, my wife and I were awoken in the night by a beeping．There，in the stillness， we went through the possible suspects．Could we have a text message? Could it be any of the devices(装置)able to make a sound? Curling iron, rice cooker, smoke detector, TV set，clock radio．．．
The only way to tell was to chase the sound down ，but no sooner would we pull on our bathrobes than the beeping would stop. We didn’t hear it every night but often enough that we would climb into bed wondering whether our sleep would be interrupted by that maddening sound，that beep．
Finally,early one morning，my wife found it：in the study,under a desk，a big plastic cube that was plugged into the wall．It was an uninterruptible power supply that we’d inherited(继承)from my wife’s mother．We’d never known it was capable of speech．
I think it just wanted someone to talk to.
14．What does the writer truly mean by saying“I hear America beeping”?
A．American people like devices that beep．
B．Americans are crazy about sending text messages．
C．In modern society people are dependant on technology．
D．The soundtrack to modern life is no longer natural．
15．Why couldn’t the author and his wife find the source of the noise in their house in the beginning?
A．There were too many devices for them to check．
B．They were unwilling to get up at midnight．
C．They had never known that thing could beep too．
D．The noise didn’t come every day．
16．After reading this passage，we can probably tell the author ．
A．enjoys being surrounded by beeps B．has a touch of humor in his writing
C．tries to avoid using anything that beeps
D．understands the beeping is designed to be user-friendly
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 latest and most surprising discovery is pieces of silk found in the hair of an 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 when an 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 and brought back knowledge of even more distant lands such as Persia, Syria and a place known as Lijien, perhaps Rome. Historians 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 Persia in exchange for acrobats and ostrich eggs, was soon finding its way through a network of merchants to the luxury markets of 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. The word “coupled” in the first paragraph could best be replaced by ______.
| A．produced | B．contributed | C．doubled | D．combined |
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 |
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 |
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 |
Many people write to newspaper and magazines to express their opinions. Letters to the editor must carry the writer’s 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 a seal of consent, an agreement to take the matter seriously. Most governments and many organizations will not process written 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 use 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. 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. |
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 |
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 |
The passage is mainly about _______.
| A．honour and writers | B．identity and signature |
| C．signature and responsibility | D．anonymity and signature |
| 237 West Palmdale Boulevard Fresno, California 93706 AmToy Corporation Suite 15 TransAm Building San Francisco, California 94115 November 20, 2008 Dear Sirs, As a concerned parent, I am writing to protest your recent advertisement for Electro-Robo seen in local media is California. Specifically, I am referring to newspaper and magazine ads（attached to this letter）published the week of November 15. Children respond to your type of advertising in an immature way; that is, they are unable to understand how expensive some toys are for middle-class parents. Further, you product is violent in nature. Youth advertisement gives children the impression that it's fine to have "two guns and laser eyes." You also suggest that children need your toy to protect them "when you go outside." This is not a healthy attitude for children to have. I hope you will stop advertising your product in such a way that may harm our children. Sincerely yours, （Mrs.） Alma Hernandez President, Parents for Non-violent Toys Enc. |

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. |
