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.
1. The author writes this passage mainly to________.

2. The first sentence probably refers to ________.
A. there will be more and more green land in China
B. China is still young and lacking experience
C. China"s new cars are combinations of different green models
D. China has started producing environmentally friendly cars

way to find out: Photograph it with a cellphone and send the image to an expert.With cellphones becoming common in Japan and rising concern over expanding waistlines, healthcare providers will allow the
calorieconscious people to send photos of their meals to nutritionists for advice.
Public health insurance offices in Osaka in Western Japan have launched the service on a trial basis.
About 100 cardiac patients signed up in the first year, followed by diabetes and obesity patients in the
second. "Japanese have been getting fatter, especially men in their 20s and 30s. There is concern over
what they learned about nutrition when they were younger," the Osaka official, Satomi Onishi said.
"We"re hoping that this program can help us deal with the problem."
Osaka is using a system developed by Asahi Kasei Corp. The system is operating among about 150
healthcare providers and local governments around the country. Nutritionists can work with photos from
one day"s meals to several weeks" worth. Results come back in three days. People can also log on a
website to get further information.
Dr Yutaka Kimura has developed a similar system at Kansai Medical University"s Hirakata Hospital,
also in Osaka. Five patients have taken part in the programme, which costs $37 to join and $21 per
month. Patients photograph meals over the course of three to seven days, and a nutritionist emails advice
to them. "Patients used to fill in meal logs, but people tend to forget things or underestimate their portions," Kimura said. "Photographing meals and emailing them can be easier and get more accurate results."
As Japanese have turned to bigger portions and more meat and fried foods,obesity and related illnesses such as high blood pressure have become a rising concern. The Health Ministry estimated last year that
more than half of Japanese men and about one in five women between 40 and 70 years old were at the
increased risk of heart disease, type ? diabetes and other diseases because of obesity. With the Health
Ministry hoping to see a 25% reduction in the number of people at the risk of these diseases by 2015,
Osaka officials hope the cellphone program will help.

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 ________.

about it?
The results of two surveys, one of primary care physicians and the other of patients, found that while
most doctors want to help patients lose weight and think it is their responsibility to do so, they often don"t
know what to say.
So while doctors may tell patients they are overweight, the conversation often ends there, said
Christine C. Ferguson, director of the Stop_Obesity_Alliance. Without being told about options for
diabetes, she said, "Doctors don"t feel they have good information to give. They felt they didn"t have
adequate tools to address this problem."
The lack of dialogue hurts patients, too. The patient survey, of over 1,000 adults, found that most
overweight patients don"t even know that they" re too heavy. Only 39 percent of overweight people
surveyed had ever been told by a health care provider that they were overweight.
Of those who were told they were obese,90 percent were also told by their doctors to lose weight,
the survey found. In fact most have tried to lose weight and may have been successful in the past-and
many are still trying, the survey found. And many understand that losing even a small amount of weight
can have a positive impact on their health and reduce their risk of obesityrelated diseases like
hypertension and diabetes.
Dr. William Bestermann Jr., medical director of Holston Medical Group, in Kingsport, Tenn. , which
ranks the 10th in obesity among metropolitan areas in the United States, said the dialogue had to be an
ongoing one and could not be dropped after just one mention of the problem. "If you"re to be successful
with helping your patients lose weight, you have to talk to them at actually every visit about their progress, and find something to encourage them and coach them, " he said.
He acknowledged that many doctors tend to be not optimistic.
"Part of this is that there"s this common belief, and doctors are burdened by it, too, that overweight
people are weakwilled and just don"t have any willpower and are selfindulgent and all that business, "he
said. "If you think that way, you"re not going to spend time having a productive conversation."
1. What is the "Stop Obesity Alliance" most probably in Paragraph 3?
A. An organization of doctors specializing in obesity.
B. An organization of patients suffering from obesity.
C. A research group that conducts special surveys about overweight people.
D. A research group dealing with doctorpatient relationship.
2. How many of the patients surveyed have been advised by their doctors to lose weight?
A. About 350.

C. About 900.
D. 1,000.
3. What can be inferred about obesity patients in Paragraph 5?
A. They are not as hopeless as doctors think they are.
B. Most of them have tried hard to lose weight, but in vain.
C. Without their doctors" constant coaching, there is little chance of their succeeding in losing weight.
D. Most of them have just given up their hope of becoming less heavy.
4. According to the passage, which factor contributes to the lack of dialogue between doctors
and patients?
A. Most doctors just never think of warning their patients about their weight problem.
B. Many doctors find it difficult to persuade overweight people to lose weight.
C. Most patients are too weakwilled to do anything about their weight.
D. Many patients tend not to trust their doctors about their weight problem.

disease,also known as sleeping sickness. The drugs will be given out in Uganda and the Democratic
Republic of the Congo.
Officials says the new treatment has fewer side effects. It is also more effective and less costly than
the drugs traditionally used. In addition,the new treatment reduces the number of injections needed. And
it shortens the amount of time patients must spend in hospital.
Sleeping sickness threatens millions of people in 36 countries in Africa. Most live in poor rural areas.
The disease is caused by the trypanosoma parasite(寄生物). It is spread to humans through the bite of
infected tsetse flies. Common signs of sleeping sickness include fever,headaches,extreme tiredness and
pain in the muscles and joints. Early identification of the disease may be difficult because many infected
people do not show any immediate symptoms. Over time,the parasites invade the central nervous system. The disease causes sleep disorders,mental confusion,personality changes and speech problems. If left
untreated,sleeping sickness kills.
It"s estimated that about 60,000 people are currently infected with the disease. It develops in two
different forms. Trypanosoma gambiense is responsible for 90% of the reported cases of sleeping
sickness. People infected with this form may develop the disease over many years without any major
symptoms. Until now the drug melarsoprol is used to treat patients in the advanced stage of sleeping
sickness. But the drug requires many painful injections several times a day for several weeks. It also
causes bad side effects,some of which can be deadly.
In Uganda,a new study has confirmed earlier research linking the spread of sleeping sickness to
infected farm animals. The writers of the study have called for stronger rules requiring cattle to be treated
before being sold at market.
1. The following are the advantages of the new treatment EXCEPT ________.
A. having an intended effect
B. low price
C. reducing injections and hospitalization
D. no bad side effects
2. It is hard to identify sleeping sickness in the early stage because ________.
A. it is spread to humans through the bite of infected tsetse flies
B. the infected patients live in poor conditions
C. there are so many infected people in Africa
D. the symptoms of the disease doesn"t occur at once
3. Which of the following statements is WRONG?
A. Nine people in ten infected with sleeping sickness in Africa result from trypanosoma gambiense.
B. The invasion of sleeping sickness may lead to death.
C. The drug melarsoprol is used to treat patients in the early stage of sleeping sickness.
D. There are many disadvantages for the drug melarsoprol to control sleeping sickness.
4. It can be inferred from the last paragraph that ________.
A. farm animals infected by trypanosoma parasite is a main source of sleeping sickness
B. all the animals must be get rid of by the government
C. there isn"t any rules requiring cattle to be treated before being sold at market in Uganda
D. cattle is forbidden to enter the market before being infected by trypanosoma parasite
5. The passage is primarily written to ________.
A. explain the importance of good sleep habits
B. provide the latest medical treatment information
C. prevent African trypanosomiasis disease
D. introduce the common signs of sleeping sickness
