The World Health Organization says obesity rates are rising in Pacific island countries.So, too, are
health problems linked to being overweight.
The WHO says a major reason for the rising obesity rates is an increase in imported foods.It says many Pacific islanders have replaced their traditional diets of vegetables and fruits with imported processed
foods.
Dr.Temu Waqanivalu is with the World Health Organization"s South Pacific office in Suva, Fiji.He says many of the imported products lack nutritional value.
Temu Waqanivalu said:"In some of the places, you"d be amazed to see how a bottle of Coke is cheaper than a bottle of water.I think that represents the kind of offenvironment we"ve created that doesn"t really
encourage or make lifestyle choices an easy choice for the population."
And a lack of physical activity among many Pacific islanders only adds to the obesity problem.
The WHO says more than 50 percent of the population is overweight in at least ten Pacific island
countries.The rate is as high as 80 percent among women in the territory of American Samoa.Fiji had the
lowest obesity rate at 30 percent.
In all, almost ten million people live in Pacific island countries.The WHO estimates that about 40
percent of them have health disorders related to diet and nutrition.
Diabetes rates are among the highest in the world.Fortyseven percent of the people in American
Samoa have diabetes.So do 44 percent of the people in Tokelau, a territory of New Zealand.
By comparison, the diabetes rate is 13 percent in the United States, a country that has its own
problems with rising obesity.
Officials also note an increase in nutritional problems like anemia and not enough vitamin A in the diets of Pacific islanders.Dr.Waqanivalu says treating conditions related to obesity and diet puts pressure on
limited health resources and budgets.
1. The main reason why obesity rates are rising in many Pacific islanders is ________.
A. the change of society
B. the change of eating habits
C. the change of life style
D. lack of exercise
2. Imported products lack nutritional value but people love to buy them because ________.
A. they are cheap
B. they are popular
C. they are tasty
D. they are convenient to get
3. How many people living in Pacific island countries have health disorders?
A. 1 million.
B. 4 million.
C. 6 million.
D. 10 million.

over time,according to a Japanese study that covered thousands of people．
Green tea contains antioxidant chemicals that may help ward off the cell damage that can lead to
disease．Researchers have been studying green tea"s effect on everything from cholesterol(胆固醇)to
the risk of certain cancers,with mixed results so far．
For the new Japanese study,researchers decided to examine the question of whether green tea
drinkers have a lower risk of frailty and disability as they grow older．
Tomata and his colleagues followed nearly 14,000 adults aged 65 or older for three years．
They found those who drank the most green tea were the least likely to develop "functional disability",
or problems with daily activities or basic needs,such as dressing or bathing．
Specifically,almost 13 percent of adults who drank less than a cup of green tea per day became
functionally disabled,compared with just over 7 percent of people who drank at least five cups a day．
The study did not prove that green tea alone kept people active as they grew older．
Green-tea lovers generally had healthier diets,including more fish,vegetables and fruit,as well as more
education．lower smoking rates,fewer heart attacks and strokes,and greater mental sharpness．
They also tended to be more socially active and have more friends and family to rely on．
Although it"s not clear how green tea might offer a buffer(缓冲剂)against disability,Tomata"s team
did note that one recent study found green tea extracts(提炼物)seem to increase leg muscle strength
in older women．
While green tea and its extracts are considered safe in small amounts,they do contain caffeine and
small amounts of vitamin K,which means it could block drugs that prevent blood thickened．
B．Green tea makes you less disabled．
C．Green tea makes you more friendly．
D．Green tea makes you more educated．
B．absorb
C．remove
D．prevent
B．know if green tea drinkers are independent
C．help nearly 14,000 adults aged 65 or older
D．study green tea"s effect on cholesterol
B．Keep old people active．
C．Make more friends．
D．Suffer fewer heart attacks．
B．green tea should be drunk pr
operlyC．green tea is poisonous for old people
D．vitamin K is helpful to us
China_is_going_green. In order to reduce air pollution and oilshortages, automobile manufacturers have announced their plans to develop hybrid vehicles (混合燃料汽车) for the Chinese market. Toyota"s
hybrid car Prius will be ready to drive in China this week. Let"s have a look at the new car.
Any vehicle is a hybrid when it combines two or more sources of power. Hybrid cars run off a
rechargeable battery and gasoline. Hybrid cars have special engines, which are smaller than traditional
gasoline engines. They run at 99 percent of their power when the car is cruising (匀速行驶). A specially
designed battery motor provides extra power for running up hills or when extra acceleration is needed.
Step into a Prius, and turn on the engine. The first thing you notice is how much quieter it is than a
traditional car. At this point, the car"s gasoline engine is dormant (休眠). The electric motor will provide
power until the car reaches about 24 km/h. If you stay at a low speed, you are effectively driving an
electric car, with no gasoline being used, and no waste gas gives off.
The onboard(车载的) computer makes the decision about when to use a gas engine, when to go
electric, and when to use a combination of the two. If you go over 24 km/h, when you step on the gas
pedal (油门), you are actually telling the computer how fast you want to go.
The electronic motor recharges automatically using a set of batteries. When driving at high speed, the
gasoline engine not only powers the car, but also charges the batteries. Any time you use the brake, the
electric motor in the wheels will work like a generator and produce electricity to recharge the batteries. As a consequence, the car"s batteries will last for around 200,000 miles.

A. teach people how to drive a hybrid car
B. introduce a new kind of "green" car
C. show how to save their gasoline when driving a car
D. announce plans to develop hybrid vehicles for China

D. A specially designed battery motor provides extra power when needed.
4. What is the most important feature of hybrid cars?
A. They are powered by both a rechargeable battery and gasoline.
B. They are much quieter than traditional cars.

5. What can we conclude from the story?
A. The batteries can be recharged at any time you want.
B. Using the brake suggests that the gasoline engine should work.
C. The batteries will last for 200, 000 miles without being recharged.
D. The gasoline engine charges the batteries as well as powers the car.
Malaria, the world"s most widespread parasitic (寄生虫引起的)disease, kills as many as three million people every year-almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess
because many people don"t (or can"t) seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer
works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.
Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often,
headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the
red blood cells they infect. They can also attach themselves to blood vessels in the brain. If it doesn"t kill
you, malaria can happen again and again for years. The disease is passed on to humans by female
mosquitoes infected with one of four species of a parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth and one of the most successful. Malaria has five thousand
genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more
outbreaks in cities with large populations. Some of the disease"s spread is due to global warming.
For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have
become resistant to it. Successful alternatives that help prevent resistance are already available, but they
have been in short supply and are very expensive. If these drugs should fail, nobody knows what would
come next.

Dutch men in which deaths from heart disease were more than 50 percent lower among those who
consumed at least an ounce (盎司)of salt water fish per day compared to those who never ate fish.
The Dutch research is one of three human studies that give strong scientific support to the long
held belief that eating fish can provide health benefits, particularly to the heart.
Heart disease is the number-one killer i
n the United States, with more than 550,000 deaths occurring from heart attacks each year. But previous research has shown the level of heart disease
is lower in cultures that consume more fish than Americans do. There are fewer heart disease deaths,
for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and
among the Japanese, whose daily fish consumption(消费量) averages more than 3 ounces.
For 20 years, the Dutch study followed 852 middle-aged men, 20 percent of whom ate no fish.
At the start of the study, average fish consumption was about two-thirds of an ounce each day, with
more eating lean fish than fatty fish.
During the next two decades, 78 of the men died from heart disease. The fewest deaths were
among the group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos.
This relationship was true regardless of other factors such as age, high blood pressure, or blood
cholesterol(胆固醇) levels.
B. People who regularly eat fish never suffer from heart disease.
C. Heart disease causes more deaths in America than any other disease.
D. There is a low level of heart disease in such countries as Japan and Greenland.
B. fresh fish
C. fish that live in salt water
D. fish that have little fat
B. the effect of fish eating on people"s health
C. the changes in people"s diet
D. the daily fish consumption of people in different cultures
B. in America
C. in the countries with high consumption of fish
D. in the countries with good production of fish
