BEING an astronaut sounds cool, doesn't it? In space, they get to do some pretty amazing things, like floating in zero gravity(重力).
However, there are also plenty of things that astronauts can't do because of their weightless environment, and that's very sad. What's worse, they can't even let their sadness show – because it's impossible to cry in zero gravity.
Of course, astronauts can still produce tears. But crying is much more difficult in space, reported The Atlantic in January. Without gravity, tears don't Flow downward out of the eyes like they do here on Earth. This means that when you cry in space, your tears have nowhere to go—they just stick to your eyes.
In May 2011, astronaut Andrew Feustel experienced this during one of his spacewalks. "Tears," he said, "don't fall off of your eye... They just kind of stay there."
Besides making your Vision unclear, this can also cause physical pain. Back on Earth, tears are supposed to bring comfort to the eyes. But that's not the case in space. The space environment dries out astronauts' eyes, and when tears suddenly wet the eyes, it can cause pain rather than comfort. "My right eye is painful like crazy." Feustel told his teammate during the walk.
Since gravity doesn't work in space, astronauts need some extra help to get rid of the tears. Feustel chose to rub his eyes against his helmet to wipe the tears away. Another choice is to just wait—"When the tears get big enough they simply break free of the eye and float around," astronaut Ron Parise told The Atlantic.
There are lots of small things—things like crying – that we are so used to on Earth. We usually take them for granted, until they become a problem in a totally different environment, like space. There, astronauts can't talk to each other directly. They also can't eat or drink in normal ways. They can't even burp (打嗝), because there is no gravity to hold the food down in their stomach. If they do burp, they just end up throwing up (呕吐) everything in their stomach, according to the UK National Space Center.
Thus, perhaps it's only space explorers who can honestly say: "Gravity, you're the best."What can we conclude from paragraphs 2 and 3?

When of the following can be the best title for the text?

| B．Better life with gravity |
| C．In the sky, you can't cry |
| D．No Gravity, no tears |
Wall Street is the banking center of New York City. But how did the street get its unusual name? To find out, we must go back to the early years of exploration in North America.
New York City was first called New Amsterdam by the explorer Henry Hudson. He was working for a Dutch trading company when he entered what is now the lower Hudson River area in the year 1609. There he found an island that was a perfect trading harbor. The Manhattan Indians lived there.
Dutch traders built a town on the end of Manhattan Island. It became a rich trading center. But the British questioned the right of the Dutch to control the area. The two nations went to war in 1652.
The governor of New Amsterdam, Peter Stuyvesant, worried that British settlers in New England would attack his town. He ordered that a protective wall be built at the north edge of Manhattan. The wall was more than 2,290 feet long. It extended from the Hudson River to the East River.
The British never attacked New Amsterdam. So the wall was never tested in war. But the path beside it became known as Wall Street. Later, Wall Street became a street of banks and business.
Dealing in stocks and shares in the stock markets began in the 17th Century. An informal market developed around the coffee houses in the City of London gradually. In 1773 “New Jonathan’s” Coffee House became the informal Stock Exchange, and it was formally established till 1802. at that time London was the largest share market, and the growth of the Industrial Revolution helped the establishment of local share markets in other parts of the country --- more than 330 of them when there were most. These markets first began moves towards combination in 1890, when the Council of Associated Stock Exchanges was formed. By 1967 all the “Country” Exchanges had got together themselves into six regional exchanges, and in 1973 all seven exchanges in the British Isles came together to form The Stock Exchanges of Great Britain and Ireland, and its member firms spread from Aberdeen to the Channel Islands and from Lancaster to Limerick.

Active participation in the classroom is not only accepted but also expected of the student in many courses. Some professors base part of the final grade on the student’s oral participation. Although there are formal lectures during which the student has a passive role (I.e., listening and taking notes), many courses are organized around classroom discussions, students questions, and informal lectures.
A professor’s teaching style is another factor that determines the degree and type of student participation. Some professors prefer to control discussion while others prefer to guide the class without controlling it. Many professors encourage students to question and challenge their ideas. Students who make statements that contradict the professor’s point of view should be prepared to prove their positions.
Ideally, the teacher-student relationship at universities is characterized by trust. The “honor system” demands that the student be honest in all areas of school work. Thus, cheating on tests, presenting others’ ideas as original, and turning in homework done by someone else are all forbidden.
Violation of the honor system can result in a student’s failing a course, having a record of the violation placed in the student’s school files, or even being driven out from the university. Students who cheat may lose the respect of other students, particularly those who study for exams and work independently. When leaving the classroom while students are taking an exam, an instructor may or may not say, “I expect you all to obey the honor system.” Even if the words are not stated, the student is expected to work alone and not to share answers.
68. In many courses, teachers__________.
A. allow the students to participate
B. require the students to participate
C. both A and B
D. neither A nor B

Matsushita, the world’s largest provider of consumer electronics, has decided to move in on Hollywood. Last weekend, Matsushita company leaders met with movies VIPs from MCA, Inc., the entertainment community that produced the movies as “Jaws” and “E.T. the Extra-terrestrial”. If the negotiations are successful, Matsushita will pay somewhere between $6 billion and $7.5 billion for MCA, by far the largest U.S. buying by a Japanese company.
The deal is larger than last year’s $5 billion buying of Columbia Pictures by Matsushita’s competitor, Sony Corporation. The movement by the Japanese companies shows Tokyo’s growing interest in the entertainment world. It is surprising for both sides of the Pacific Ocean. Why does a disciplined, no-nonsense nation like Japan want to get into show business? The answer is quite simple: To make money. Japanese corporation leaders feel the global potential of the entertainment business and recognize that there is an increasing market for movies and television in the rapidly industrializing world.

Breathe, wave and smile.Along with more than 300 other seniors, I marched into the stadium on the afternoon of May 10. The audience burst into deafening cheers. The huge stadium shook with all the whistling and clapping.
It was as if a Hollywood superstar had walked on stage. And indeed, every single senior that day was a star of the moment. Each deserved it. The seniors had been preparing for four years for this once-in-a-lifetime moment—the commencement(graduation ceremony).
Seated, I waited anxiously for the opening address. As a foreign exchange student, I was not able to receive a diploma. However, I still had the wonderful feeling of being part of things. Like the other graduates, I was dressed in marron cap and gown.
Our principal, Mr Glover, delivered a short, warm greeting. The US national anthem followed and then, hands on chests, a solemn Pledge of Allegiance(美国的爱国誓言).
Students who had excelled academically gave farewell speeches. The tears in some eyes convinced me that many had deep feelings about the occasion. It was as the class motto says, “Life brings us tears, smiles and memories. The tears dry; the smiles fade; but the memories last forever.”
Then came the core(the most important part) of the commencement. Hundreds of names were announced. Each graduate walked across the stage to receive his or her diploma from the principal. From the different cheers each graduate got, we had the funny sense that it was a kind of competition of who could cheer the loudest.
To be honest, the presentation of diplomas got boring. A girl sitting next to me even started yawning. But it wasn’t boring for those receiving the diploma: they would treasure the moment the principal placed the sacred brown document in their hands for the rest of their lives.
A new page in the book of that person’s life had turned. They were glimpsing their futures: futures of challenge, hardship, perhaps loneliness too, which would take all of their courage.

The Internet has led to a huge increase in credit-card(信用卡) fraud. Your card information can even be on sale on an illegal website. Websites offering cheap goods and services should be regarded with care. Online shoppers whoenter their credit-card information may never receive the goods they thought they had bought.
The thieves then go shopping with your card number—or sell the information over the Internet. Computer hackers(黑客)have broken down security system, raising questions about the safety of card holder information.
Several months ago, 25,000 customers of a CD universe, an online music retailer(批发商), were not lucky. Their names, addresses and credit-card numbers were posted on a Website after the retailer refused to pay $ 157,828 to get back the information.
Credit-card firms are now fighting against online fraud. Master-card is working on plans for web-only credit-cards, with a lower credit limit. The card can be used only for shopping online. However , there are a few simple steps you can take to keep from being cheated.
Ask about your credit-card firm’s online rules: under British law, cardholders are responsible for the first $ 78 of any fraudulent spending. And shop only at secure sites: send your credit-card information only if the website offers advanced security system.
If the security is in place, a letter will appear in the bottom right-hand corner of your screen. The website address may also start with https://--the extra “s” stands for security. If in doubt, give your credit-card information over the telephone.
Keep your password safe: most online sites require a user name and password before placing an order. Treat your password with care.
