     China_is_going_green. In order to reduce air pollution and oilshortages, automobile manufacturers
have announced their plans to develop hybrid vehicles (混合燃料汽車) 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 (勻速行駛). 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(車載的) 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 (油門), 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.

     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.

     Christopher Thomas, 27, was a writer by night and a teacher by day when he noticed he was always
tired and was losing weight fast. Diagnosed with diabetes(糖尿病), Thomas would need to inject himself with insulin(胰島素) three times a day for the rest of his life or risk nerve damage, blindness, and even
death. And if that weren't bad enough, he had no health insurance.
     After a month of feeling upset, Thomas decided he'd better find a way to fight back. He left Canton,
Michigan for New York, got a job waiting tables, nicknamed himself the Diabetic Rockstar, and created
diabeticrockstar.com, a free online community for diabetics and their loved ones-a place where over
1,100 people share personal stories, information, and resources.
    Jason Swencki's son, Kody, was diagnosed with diabetes at six. Father and son visit the online children's forums(論壇) together most evenings. "Kody gets so excited, writing to kids from all over, " says
Swencki, one of the site's volunteers. "They know what he's going through, so he doesn't feel alone."
     Kody is anything but alone: Diabetes is now the seventh leading cause of death in the United States,
with 24 million diagnosed cases. And more people are being diagnosed at younger ages.
     These days, Thomas's main focus is his charity(慈善機構(gòu)), Fight It, which provides medicines and
supplies to people-225 to date-who can't afford a diabetic's huge expenses. Fightit.org has raised about
$ 23,000-in products and in cash. In May, Thomas will hold the first annual Diabetic Rockstar Festival
in the Caribbean.
     Even with a staff of 22 volunteers, Thomas often devotes up to 50 hours a week to his cause, while
still doing his fulltime job waiting tables. "Of the diabetes charities out there, most are putting money into
finding a cure, " says Bentley Gubar, one of Rockstar's original members. "But Christopher is the only
person I know saying people need help now."
