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 |

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.When their American identity was called into question during a follow-up study, Asian-American participants also tended to choose typical American dishes，such as hamburgers and cheese sandwiches．In that experiment, 55 Asian-Americans were asked to choose a meal from a local Asian or American restaurant. Some participants were told that only Americans could participate in the study. Those who chose the more typical American fare ended up consuming an extra 182 calories，including 12 grams of fat and 7 grams of saturated fat（饱和脂肪）.
"People who feel like they need to prove they belong to a culture will change their habits in an attempt to fit in，"said Sauna Cheryan，an author of the study and assistant professor of psychology at the University of Washington." If immigrants and their children choose unhealthy American foods over healthier traditional foods across their lives，this process of fitting in could lead to poorer health." Cheryan added．
Social pressures，the study concluded, are at the heart of the problem．"In American society today, being American is associated with being white．Americans，who don"t fit this image even if they were born here and speak English，feel that pressure to prove that they"re American," said Cheryan．

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.

This is done by preparing the green tea just like the way it was prepared before—by washing the leaves right after pulling off them from the bush, then boiling them.There have been many healthful claims saying that drinking green tea-based products help a lot in improving the general health of their body. For a long time, there has been many beliefs saying that green tea can help, cure beriberi disease(脚气病), treat wounds, and even prevent tiredness. Now modern technology
determines that there are even added healthful benefits that include reducing the possibility of having a heart disease and helping people to lose more weight easily. Besides, studies have found out that green tea has Polyphenols(多酚类), a type of flaonoid(类黄酮) that greatly reduces the amount of time of cell maturation. The flavonoid found in green tea is called EGCg- a stronger matter than Vitamin C and E. It is believed to be 20 times stronger than these mentioned vitamins.
Having two cups of green tea daily is a good routine for your body. However, most doctors would suggest drinking at least 4 cu
ps a day is the best. You can slowly increase the amount of drinking it to allow your body to get used to it. There is nothing to lose but everything to gain in drinking green tea.小题1:Which of the following shows the right order according to the passage? _______.

My eating habits had to change in a big way. With diabetes, I can’t eat a lot of sugar or carbohydrates. I have to figure out exactly how much sugar I plan to eat, and then I get an injection of insulin before the meals to help my body process the food. Also, I test my blood-sugar level often. I’m always trying to keep my blood sugar at a healthy level. The level can drop when I exercise, but that doesn’t keep me out of gym class or off the basketball court ------ I just keep some juice boxes around to boost my blood sugar if I need to.
It’s a lot of work ------ and not a lot of fun ------ to keep track of everything, but I’ve gotten used to my new habits. I was a little scared at first because I wasn’t sure how my life would change. Once I knew what I needed to do, though, it wasn’t a big deal. My life is different now from what it was before, but it has become completely regular to me.
小题1:The first paragraph is mainly about ______.
| A．who found the author had diabetes |
| B．the author’s life before having diabetes |
| C．how the author was found to have diabetes |
| D．the author’s eating habits before having diabetes |
| A．change people’s eating habit | B．help process the food |

| B．She controlled her blood-sugar level strictly. |
| C．She stopped eating food with natural sugar. |
| D．She tested her blood-sugar level before every meal. |
| A．Increase. | B．Control. | C．Absorb. | D．Test. |
| A．Worried. | B．Frightened. | C．Pessimistic. | D．Positive. |
The most widespread mistake of all is that colds are caused by cold. They are not. They are caused by viruses passing on from person to person. You catch a cold by coming into contact directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated Arctic regions, explorers have reported being free from colds until coming into contract again with infected people from the outside world by way of packages and mail dropped from airplanes.
During the First World War, soldiers who spent long periods in the
trenches, cold and wet, seldom caught colds.In the Second World War, prisoners at Auschwitz concentration camp, naked and starved, were astonished to find that they seldom had colds.
At the Common Cold Research Unit in England, volunteers took part in experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in a room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.
If then, cold and wet have nothing to do with catching colds, why are they more frequent in winter? Despite the most hard research, no one has yet found out the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and that makes it easier for cold viruses to be passed on.
No one has yet found a cure for the cold. There are drugs and pain-killers such as aspirin, but all that they do is to relieve the symptoms.
小题1:The writer offered ___ examples to support his argument.
| A．4 | B．5 | C．6 | D．3 |
| A．they are working in the isolated Arctic regions |
| B．they are writing reports in terribly cold weather |
| C．they are free from work in the isolated Arctic regions |
| D．they are coming into touch again with the outside world |
| A．suffered a lot | B．never caught colds |
| C．often caught colds | D．became very strong |
| A．the experiments on the common cold |
| B．the fallacy about the common cold |
| C．the reason and the way people catch colds |
| D．the continued spread of common colds |
