In the United States, 30 percent of the people have a “weight problem”. To many people the cause is obvious (明显的): they eat too much. But scientific evidence (证据) does little to support this idea. Going back to America of 1910, we find that people were thinner than today, yet they at

e more food. In those days people worked harder physically, walked more, used machines much less, and didn’t watch television.
Several modern studies, moreover, have shown that fatter people don’t eat more on average than thinner people. A 1979 study of 3,545 London office workers showed that fat people eat less than slim (苗条的) people.
Studies also show that slim people are more active than fat people. A study by a research group at Stanford University found the following interesting facts:
The more the man ran, the greater loss of the body fat.
The more they ran, the greater increase in food intake.
Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.

小题2: According to the passage, how many people in 900 Americans have a “weight problem”?

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.
小题1:The passage mainly talks about _____.

A．the rule of forbidding chewing gum in school

B．new research on chewing gum

C．different kinds of chewing gum

D．the relationship between chewing gum and medicine

小题2:What does the underlined word “hits” in Paragraph 6 probably mean?

A．Touches.

B．Attacks.

C．Takes effect.

D．Affects badly.

小题3:According to the passage, Stay Alert is a gum which can help people _____.

A．stay awake	B．fight colds
C．cure headaches	D．overcome nervousness

小题4:It can be inferred from the passage that _____.

A．stay Alert is not easy to store

B．stay Alert needs water to swallow

C．stay Alert is available to the public now

D．we can’t buy gums which cure bad breath now

After moving to the United States, immigrant group

s trying to fit in tend to choose high calorie fatty foods in an attempt to appear more American，a new study finds．That"s one reason why immigrants approach US levels of obesity within 15 years of moving to America．
The researchers also did an experiment that measured whether or not the threat of appearing un-American influenced respond

ents" food choices．After being questioned about their ability to speak English，75 perce

nt of Asian-Americans identified a typical American food as their favorite. Only 25 percent of Asian-Americans who had not been asked if they spoke English did the same.

Ever since news of widespread food recalls caused by a carcinogenic dye（颜料） broke, there has been confusion over possible links to the country of the same name, but Sudan officials say there is no connection whatever.
Sudan1 is a red industrial dye that has been found in some chilli powder, but was banned in food products across the European Union (EU) in July 2003.
Since the ban was put in place, EU officials have been striving to remove some food products from the shelves. So far 580 products have been recalled.
Last week Sudan’s Embassy in the United Kingdom asked the Food Standards Agency (FSA) for clarification of the origin of the dye’s name.
Omaima Mahmoud Al Sharief, a press official at Sudan’s Embassy in China, explained the purpose of the inquiry was to clear up any misunderstanding over links between the country and the poisonous dye.
　

　"We want to keep an eye on every detail and avoid any misunderstanding there," she said. "Our embassy to Britain asked them how the dye got that name and whether the dye had something to do with our country. But they told us there was no relationship."
The FSA, an independent food security watchdog in Britain, received a letter from the Sudanese embassy last week.
　"They asked us why the dye is named Sudan, however, we also do not know how it got the name," she said. "People found the dye in 1883 and gave it the name. Nobody knows the reason, and we cannot give any explanation before we find out."
Sudan dyes, which include Sudan1 to 4, are red dyes used for colouring solvents（溶剂）, oils, waxes, petrol, and shoe and floor polishes. They are classified as carcinogens by the International Agency for Research on Cancer.
