allergies. The most common cause is pollen (花粉), which is usually produced by trees in
the spring, grasses in the summer and weeds in the fall, as part of their reproductive
process.
Other causes include organisms, chemicals, plants and dead skin particles (微粒) from
dogs and cats can also cause allergic reactions. So can insect stings and some food.
The most common kind of allergic reactions is itchy (痒的), watery eyes and a blocked
or watery nose. Allergies can also cause red, itchy skin. Some reactions can be life-
threatening, for example, when breathing passages become blocked.
It is not always easy to avoid allergies. Drugs may offer an effective treatment.
Another treatment used in some cases is called immunotherapy (免疫疗法). A patient is
injected with small amounts of the allergy-causing substance. The idea is that larger and
larger amounts are given over time until the patient develops a resistance in his body.
In the United States, experts estimate that up to 8% of young children have food
allergies. Every year these allergies cause about 30,000 cases with severe reactions that
require immediate treatment. It can result in breathing trouble and in some cases death.
It is said that about 100 to 200 people will die. It says most of the reactions are caused
by peanuts and tree nuts like walnuts.
People can also be allergic to medicines. The American Academy of Allergy, Asthma and
Immunology says about 10% of bad reactions to commonly used medicines are allergic. In
other words, a person"s immune system overreacts and produces an allergic reaction. The
most common reactions include skin rashes (皮疹), itching, breathing problems and swelling
in areas such as the face.

today. The research also shows that the difference in life expectancy (预期寿命)
between rich and poor becomes smaller among those who live in an environment
with parks and trees.
Richard Mitchell, from Glasgow University, and his colleagues, found that the gap
between the number of deaths of people on high incomes and the number of deaths
of those on low incomes in green areas was half that compared with figures relating
to built-up areas.
Green spaces, classified by the researchers as "open, undeveloped land with natural
vegetation", encouraged people to walk and be more active. Exercise in these settings
could have greater benefits than exercise elsewhere, the researchers said.
The benefits potentially go beyond exercise. Studies have shown that being around
green spaces can reduce blood pressure and stress levels, and possibly help patients
recover faster.
A number of researchers have looked at the effects of greenery on our well-being.
But few studies had looked at whether living in green areas reduced health inequalities,
the Glasgow team said.
Using information from a land-use database of 2001, the researchers divided the
pre-retirement population of England into four groups according to income level, and
five groups according to access to green space. They then looked at death rate for
2001～2005. They found that the inequality in death rate from all causes relating to lack
of money was less in those populations in the greenest areas compared with the figures
for people living in more built-up places.
They found an even stronger relationship when it came to deaths from certain diseases
such as heart conditions and stroke (中风). There was no difference, however, in deaths
from lung cancer.
The researchers said that changing the physical environment was an easier way to fight
against poor health than using media campaigns or giving out information on health. "The
result of the study is clear: Environments that promote good health might be very important
in the fight to reduce health inequalities."
B. the number of deaths
C. the income
D. the living area
B. They encouraged people to exercise in green areas.
C. They studied the effects of greenery on people"s health.
D. They focused on the influence of greenery on health inequalities.
B. People should take more exercise every day.
C. More trees and grass should be planted in cities.
D. People should help to fight against health problems.
B. Green spaces promote good health.
C. Income influences health less than environment.
D. Exercise in green areas benefits people a lot.
bottle fell out of her purse. She quickly put it back in, but not before the camera recorded the event. Neither
Spears nor her spokesman was willing to comment on the contents of the bottle, but the next morning London"s
Daily Express published a page of pictures under the headline "EXCLUSIVE: POP PRINCESS SPOTTED AT
AIRPORT WITH POT OF SLIMMING TABLETS. " Spears was apparently carrying Zantrex-3, one of the
most popular weight-loss pills now sold in the United States. The pill, which is sold at about fifty dollars for
a month"s supply, contains a huge amount of caffeine, some green tea, and three common South American
herbs that also act as stimulants (兴奋剂). It hit the U.S. market last March and has had a success that would
be hard to overstate. Millions of bottles have been sold, and during the Christmas season it was displayed in the
windows of the nation"s largest chain of vitamin shops, G.N.C. (It is so highly sought after that many of the
stores keep it in locked counters.) Zantrex-3 is also sold at CVS, Rite Aid, Wal-Mart, and other chains, and over
the telephone and on the Internet. If you type "Zantrex" into Google, more than a hundred thousand pieces of
information about it will appear. At any moment, there are scores of people sell it on eBay.
Perhaps the most interesting thing about the success story of Zantrex-3, however, is that it is far from
unique.There are hundreds of similar products on the market today, and they are bought by millions of
Americans. And though Zantrex"s producer makes some exciting statements ("the most advanced weight
control compound (化合物) period"), so do the people who sell Stacker 2 and Anorex along with those who
sell Carb Eliminator and Fat Eliminator. Almost all of these compounds suggest that they can help people lose
weight and regain lost energy, and often without diet, exercise, or any other effort.
B. singer
C. athlete
D. chemist
B. Rite Aid
C. Wal-Mart
D. Anorex
B. you can"t overstate the success of Zantrex-3
C. you can"t think too highly of the success of Zantrex-3
D. Zantrex-3 is not very successful
B. Zantrex-3 is the most successful weight-loss pills on the US market
C. Zantrex-3 is the only weight-loss pill on the US market
D. there are five kinds of weight-loss pills on the US market
B. how Zantrex-3 became successful in the USA
C. weight-loss pills are very popular in the USA

| Before 1900, many theories existed as to the cause of yellow fever (黄热病). Some doctors were sure the disease was air-born; others felt that it was spread from person to person. Dr. Carlos Finlay, a well-known Cuban doctor of that time, had long held the theory that it was caused by the bite of mosquitoes (蚊子). But neither the pubic nor the doctors then accepted his idea. Despite this, Walter Reed, an American doctor sent to study yellow fever in Cuba, went to talk with Finlay. Reed, after reading a lot on the subject, had begun to think that Dr. Finlay might be right. Then Reed and his comrades set to work at once. Outside Havana, they set up a laboratory and began experiments to test the theory. The experiments were successful. Now we know: A period of about two weeks must pass before a mosquito, after feeding on a sick person, could infect another person. The sick person had to have yellow fever a certain number of days before the mosquito biting him was able to carry the disease. | |||

| Is there anything more important than health? I don"t think so. "Health is the greatest wealth." wise people say. You can"t be good at your studies or work well when you are ill. If you have a headache, toothache, backache, earache or bad pain in the stomach, if you complain of a bad cough, if you run a high temperature and have a bad cold, or if you suffer from high or low blood pressure, I think you should go to the doctor. The doctor will examine your throat, feel your pulse, test your blood pressure, take your temperature, sound your heart and lungs, test your eyes, check your teeth or have your chest X-rayed. After that he will advise some treatment, or some medicine. The only thing you have to do is to follow his advice. Speaking about doctor"s advice, I can"t help telling you a funny story. An old gentleman came to see the doctor. The man was very ill. He told the doctor about his weakness, memory loss and serious problems with his heart and lungs. The doctor examined him and said there was no medicine for his disease. He told his patient to go to a quiet place for a month and have a good rest. He also advised him to eat a lot of meat, drink two glasses of red wine every day and take long walks. In other words, the doctor advised him to follow the rule:"Eat at pleasure, drink with measure and enjoy life as it is." The doctor also said that if the man wanted to be well again, he shouldn"t smoke more than one cigarette a day. A month later the gentleman came into the doctor"s office. He looked cheerful and happy. He thanked the doctor and said that he had never felt a healthier man. "But you know, doctor," he said, "it"s not easy to begin smoking at my age." | |||

| [ ] | |||

| [ ] | |||
| A. without examining the patient B. after he has examined the patient C. if the patient doesn"t take medicine D. unless the patient feels pain | |||
| 3. The underlined part means "_____". | |||
| [ ] | |||
| A. he was feeling better than ever B. he wasn"t a healthy man C. he was feeling worse than before D. he will be well again | |||
| 4. From the last sentence of the passage, we learn the man _____ before the doctor told him not to smoke more than one cigarette a day. | |||
| [ ] | |||
