Most schools forbid chewing gum(嚼口香糖), but in a few years they might consider changing that rule. Why? Scientists are finding evidence that gum chewing may be good for your health. It may even help improve your test scores. This exciting research is just beginning. And in the meantime, companies are also experimenting with adding vitamins, minerals, medicines, and other substances that could give gum the power to cure headaches and fight everything from serious diseases to bad breath.
Other researchers are finding that gum might work better than a pill to deliver medicines and other substances into the bloodstream. That’s because the lining (膜) of our cheeks can absorb certain substances more quickly than our stomachs and intestines (肠) can. That discovery could help other researchers develop medicine-containing gums that fight colds, ease headaches, battle nervousness, and
more. Scientists might even create anti-microbial (抗菌的) gums that cure bad breath.
Those projects may take years, but gum scientists have already had at least one recent success: They’ve created a gum that could help us stay awake. Researchers have produced a gum called Stay Alert. Each stick has as much caffeine as a cup of coffee. It can take an hour for the caffeine in coffee to have its full effect, but the caffeine in Stay Alert hits in just a few minutes. The gum is easy to transport and it’s stable in cold and hot climates. Unlike a pill, it doesn’t require water to swallow. Those qualities make it easy for soldiers to use. For now, Stay Alert is available only to the military (军队). The manufacturer may one day offer it for sale to the public. People who work at night, such as truck drivers and medical personnel who ride in ambulances, might benefit from a product like Stay Alert.The passage mainly talks about _____.

Arthur Miller(1915—2005) is universally recognized as one of the greatest dramatists of the 20th century.Miller’s father had moved to the USA from AustriaHungary，drawn like so many others by the “Great American Dream”．However，he experienced severe financial hardship when his family business was ruined in the Great Depression of the early 1930s.
Miller’s most famous play，Death of a Salesman，is a powerful attack on the American system，with its aggressive way of doing business and its insistence on money and social status as indicators of worth.In Willy Loman，the hero of the play，we see a man who has got into trouble with this system.Willy is “burnt out” and in the cruel world of business there is no room for sentiment：if he can’t do the work，then he is no good to his employer，the Wagner Company，and he must go.Willy is painfully aware of this，and at a loss as to what to do with his lack of success.He refuses to face the fact that he has failed and kills himself in the end.
When it was first staged in 1949，the play was greeted with enthusiastic reviews，and it won the Tony Award for Best Play，the New York Drama Critics’ Circle Award，and the Pulitzer Prize for Drama.It was the first play to win all three of these major awards.

A T-shirt a day has kept unemployment away for an American man who is making about ＄ 85,000 a year by selling advertising space on his shirt.
Jason Sadler,26,was once a former marketing expert from Florida. In 2008, he founded his own company, “I wear your shirt”,with the idea to wear a T-shirt supplied by any company and then use social media tools to develop the company. Sadler charges the “face value” of the day for his human billboard(广告牌)service. So January 1 costs ＄1,while December 31 costs ＄365. He said this may not sound like a lot, but it adds up to ＄66,795 a year if he sells out every day, which he did this year. He also sells monthly sponsorships (赞助) for ＄1,500,adding another ＄18,000 to his income.
“I walk around, take photos, wear the shirt all day... I blog about those photos. I put them up on Twitter. I change my Facebook introduction... and then I do a Youtube video. I made about ＄83,000 this year,” Reuters Television. The average U. S. income is about ＄615 a week or about ＄ 32,000 a year,according to the U. S. government.

Neil Armstrong took“one small step for man”when he stepped on the moon’s surface while worldfamous physicist Stephen Hawking took a “giant leap (跳跃)”for Earth’s physically disabled when he experienced eight rounds of weightlessness in what he saw as the first step in a personal goal to travel in space.
“It was amazing，”Hawking told reporters afterwards，using his wellknown computerized voice.“The zeroG part was wonderful，and the highG part was no problem.I could have gone on and on.I have long wanted to go into space，and the zerogravity flight is the first step towards space travel.”
Hawking is one of the bestknown scientists because of his bestselling works on the mysteries of black holes and the origins of the universe，and because of his increasing disability.He is almost completely paralyzed (瘫痪的) and can communicate only via facial gestures and a gesturecontrolled computer system.
Thursady’s flight was a test run to find out if Hawking is capable of a rocketpowered journey to the edge of outer space，perhaps aboard the spaceship now being developed for Virgin Galactic.That craft is due to enter service in 2009 or so，and taking such a flight would check off what Hawking has said is his“next step”．“He would have flown more if we let him，”said Noah McMahon，one of Hawking’s coaches.“He was all smiles all the time.”
Zero Gravity had originally planned to bring Hawking back to NASA’s Shuttle Landing Facility here after six upsanddowns.Hawking’s performance showed well for more tests.Zero Gravity Corp.cofounder Peter Diamandis said Hawking experienced the flight better than his physicians had expected.He noted that the four minutes Hawking spent in weightlessness was about as much time as he would spend in zeroG during a space flight.By saying“Stephen Hawking took a‘giant leap’” in the first paragraph，the writer means __________．
| A．ordinary people can not do what Hawking did |
| B．Stephen Hawking managed to jump by himself |
| C．it is not easy for a disabled person like Hawking |
| D．Hawking has finished almost all that is needed to do |
The underlined word“zeroG”in Paragraph 2 probably refers to __________．
| A．space travel |
| B．zerogravity |
| C．a personal goal |
| D．the first step |
Which of the following would the writer probably agree?
| A．Hawking was one of the workers in Zero Gravity Company. |
| B．McMahon was not satisfied with what Hawking did in this test. |
| C．Peter Diamandis bought a spaceship for Hawking to travel in space. |
| D．Hawking would spend in zeroG during a space flight for 4 minutes. |
The text mainly wants to tell us _________．
| A．Hawking takes a “giant leap”for Earth’s disabled |
| B．a spaceship will be sent into space before long |
| C．what Neil Armstrong had experienced in space |
| D．common people can also experience space flights |
