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.

1.The author writes this passage mainly to________.

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

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

3.Which of the followings is NOT true?

A.The hybrid cars reduce air pollution and oil­shortages.

B.The car's gasoline engine doesn't work until it reaches about 24 km/h.

C.This kind of car is completely controlled by an onboard computer.

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.

C.They only use 99 percent of their power to run up hills.

D.They have smaller engines than traditional gasoline ones.

       In 1957 a doctor in Singapore noticed that hospitals were treating an unusual number of influenzalike cases. Influenza is sometimes called “flu”or a “bad cold”. He took samples from the throats of patients in his hospital and was able to find the virus(病毒)of this influenza.

There are three main types of influenza virus. The most important of these are types A and B, each of them having several sub-groups(亚群). At the hospital the doctor recognized that the outbreak was because of a virus group A, but he did not know the sub-group. He reported the outbreak to the World Health Organization in Geneva. W. H. O. published the important news together with reports of the same kind of outbreak in Hong Kong, where about 15%~20% of the population had become ill.

As soon as the London doctors received the package of throat samples, they began to test them. They found that they could reproduce themselves at a very high speed. Continuing their careful tests, the doctor checked the effect of medicine used against all the known sub-groups of type A virus. On this virus, none of them was of any use.

Having separated the virus, the two doctors now made tests on some selected seleceted animals. In a short time the usual signs of the disease appeared. These experiments showed that the new virus spread easily, but that it was not a killer. Scientists, like the general public, called it simply “Asian flu”.

19. The Asian flu mentioned in the passage ____.

A. had something to do with a virus group B

B. was reported to W. H. O in Geneva by a doctor in Hong Kong

C. broke out not only in Singapore but also in Hong Kong

D. was taken from the throats of the patients in a hospital in Singapore

20. London doctors considered ____. 

A. Asian flu as a bad cold

B. there were three main types of influenza

C. it was necessary to test the other groups of virus besides group A

D. the influenza called “Asian flu”a new one

21. The Singapore doctor helped the world by ____. 

A. making those with Asian flu well again

B. killing the virus that caused Asian flu

C. finding the sub-group of the virus

D. reporting the outbreak of Geneva

22. The Asian flu virus ____.  

A. was a killer

B. was very weak

C. could reproduce very quickly

D. died very fast

Summer is a busy time for travel. For years, people have wondered whether they are safe from viruses when they travel in small, enclosed areas. They worry about close contact with others who may be sick.

The current spread of a swine flu(猪流感) virus has added to these concerns. Recently, the World Health Organization raised its warning about the new H1N1 virus to its highest level. W.H.O. Director-General Margaret Chan declared the sickness a pandemic–a disease that has spread to many nations. Given this information, many people want to know how safe it is to travel?

The answers people are getting may seem conflicting. For example, a W.H.O. statement urged nations not to close their borders or limit trade and travel. Director-General Chan said cases are generally not that serious for most people. Still, W.H.O. officials continue to report new cases across the world.

In the past, the W.H.O. and experts noted guidance for disease spread on airplanes. The experts said you could get infected only if you sit within two rows of someone who is sick. That would be a distance of up to three meters from the sick person. And this was true only if you sat there for more than eight hours.

But a travel-health expert says this guidance may not be helpful for swine flu. He suggests steps that could help prevent getting swine flu on an airplane. His advice includes keeping the airflow over your seat on the “low” position. The doctor says you should point the equipment so the flow of air is just in front of your face.

Doctors say anyone with pain, swelling(肿胀) or red skin on a leg during or after a long trip may have a blood clot(凝块). Anyone with such signs should see a doctor as soon as possible. The condition many times can be treated with drugs that thin the blood and stop the clot from moving through the body.

68.The underlined word “conflicting” is closest in meaning to ________.

A. in disagreement        B. not true                           C. the same                          D. unbelievable

69.According to Director-General Chan, the swine flu is ________.

A. a disease spread on airplanes                                B. a very dangerous disease

C. a disease requiring limit travel                              D. a widely spread disease

70.Which of the following is the travel-health expert’s opinion on traveling in an airplane?

A. It’s safe to sit within two rows of a sick person.

B. It’s helpful to keep air flowing right before your face.

C. It’s important for a passenger to stay in a plane within 8 hours.

D. It’s certain that a passenger will have a blood clot after a long flight.

71.What would be the best title for the text?

A. Stop Traveling in Case of Swine Flu                  B. Experts’ Arguments Over Swine Flu

C. Prevention of Swine Flu on the Trip                   D. No News Is the Best News
