China is going green. In order to reduce air pollution and oil shortages, 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.

On April 24th, another natural disaster—the oil spill(泄露) in the Gulf of Mexico, happened.Millions of dollars have been used to help stop the spill and to clean up the animals, beaches, and land spoiled by the oil.Unfortunately, when many of these chemicals are used, more damage is caused to the environment, especially to lives in the sea.

But governments seem to accept the risk of transporting millions of tons of oil by ship every day so that we can fill up our cars and drive around and cause even more environmental damage.Interestingly, the biggest companies in the world produce cars, and the next biggest supply the gasoline to make them run.

Of all of today's environmental disasters, an oil spill may actually be one of the least serious.Although oil is poisonous, it is a natural material.In the end, it breaks down naturally.In 1967 the tanker Torrey Canyon sank off the Scilly Isles near the coast of England and spilled 120,000 tons of oil into the ocean.If you go there today, you will find it hard to see any sign that it ever happened.      

However, we should be thinking more about reducing our dependency on oil.Governments should be encouraging research into new technologies, such as cars run by solar power(太阳能), electricity, hydrogen, and so on.Much of this research, in the past, was stopped by the oil, gas, and coal.

If the world's millions of cars were 10% more efficient(高效的),we would need many fewer tankers crossing the oceans each year.If this happened, the risks of oil spills would be reduced, and the air we breathe would be cleaner and fresher, too.

1.What is the passage mainly talking about?

A.Oil spills pollution.

B.What oil pollution is.

C.Oil tanker accidents.

D.How to reduce oil pollution.

2.How does the author support the idea that oil spills are not as serious as people believe?

A.By giving a description.

B.By making an argument.

C.By giving an example.

D.By comparing.

3.Which suggestion is made for reducing oil tank accidents according to the passage?

A.We should build safer tankers in the near future.

B.We should develop new technologies to cut oil use.

C.Tankers should not be allowed to sail near the coastlines.

D.Countries should build more oil pipelines under the sea.

4.Where can you read this article?

A.In a story book.

B.In a science magazine.

C.In a novel.

D.In a travel guide.

 

 

China is going green.In order to reduce air pollution and oil shortages, carmakers 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 run on a rechargeable battery and gas.Hybrid cars have special engines, which are smaller than traditional gas engines.The gasoline engine provides 99 percent of the power when the car is going at a steady speed. A specially designed battery motor provides extra power for running up hills or when it needs to speed up.

Step into a Prius, and turn on the engine.The first thing you notice is that it is quieter than a traditional car.At this point, the car’s gas engine is at rest.The electric motor will provide power until the car reaches about 24km/h.If you stay at a low speed, you are effectively driving an electric car, with no gas being used, and no waste gas given off.

The computer decides when to use the gas engine, when to go electric, and when to use a combination of the two.If you go over 24km/h, when you step on the gas pedal (油门), you are telling the computer how fast you want to go.

The electric motor recharges automatically using a set of batteries.And when driving at a high speed, the gas engine not only powers the car but also recharges the batteries.When you use the brake, the electric motor in the wheels will work like a generator (发电机) to produce electricity to recharge the batteries.As a result, the car’s batteries will last for around 200,000 miles.

C.China is still young and lacking in experience

D.the environment is getting better in China

67. What is the most important feature of hybrid cars?

68. We can know from the story that ________.

A. the gas engine recharges the batteries as well as powering the car

B. using the brake suggests that the gas engine should work

C. the car’s batteries will last for around 200,000 miles without being recharged

B. let people know how to save their gas when driving a car

C. teach people how to drive a hybrid car

D. introduce a new kind of “green” car
