A California family drives a car that could help protect the environment. When Jon and Sandy go to the store or to their daughters’ soccer games, they drive in high-tech style. They drive a $1 million, fuel-cell-powered car. It may be the world’s most expensive car and one of the most environmentally friendly cars. The FCX is the first fuel-cell-powered car to be used by a family anywhere in the world. The FCX uses hydrogen and oxygen for fuel. Car makers have been working to develop vehicles that are better for the environment. They are developing cars that use fuel other than gasoline. And then what is fuel cell technology? Fuel cell technology works by changing the chemicals hydrogen and oxygen into water. This process produces electricity, and water vapor which comes out of the exhaust pipe. Most cars release dangerous gases such as carbon monoxide and carbon dioxide. Many scientists say these gases are major contributors to global warming. “The FCX is driven just like any other vehicle on the road, but without the gases which pollute the environment,” scientists say. Fuel cell technology has been around since the 1800s, but scientists have yet been to perfect it. They say it may take years before the technology is ready for widespread use. Another earth-friendly car is already on the market. Hybrid cars use both gasoline and an electric motor. They are becoming more popular with customers because they cut pollution and improve fuel efficiency.

If you are planning to study in the United States, you need to consider several factors. Everyone has different opinions about where is the best place to live in. Also, the best places to live in are not always home to the best schools. Finally, many schools specialize in different areas of study. The Massachusetts Institute of Technology, for example, is a great school for computer science and technology-related fields of study. However, if you want to study oceanography（海洋学）, your interests may be better served by attending school in a place that is on a coastline or near the ocean.

Now I am sure that you know which schools are considered the best in the country. So I will tell you about which states I believe are the best to live in.

California is a nice state. Northern California specifically has very good weather. Los Angeles in southern California is another story, though. Life in LA is full of excitement and fast, and sometimes dangerous. As for me, I enjoyed the time I spent in Massachusetts, Virginia and Maryland and these states have a lot of history and culture. The weather is not as perfect as Northern California, but it is still quite nice. My favorite area of America is the Mid-west. Middle America, I think, is home to the true American sense of values. In addition, there are many good universities there.

Also, you need to think about your likes and dislikes and then research the various states. You like sunshine and hate snow? Then you probably won’t like the Midwest or even the Northeast. Open space, nature and peace? Then you probably should stay away from America’s large cities. Are you interested in government? Then Washington D. C. is the only place for you. Whatever you decide, put some thought into it. The place you live in could be the difference between a great study-abroad experience and a state of great suffering on earth.

1.What, according to the author, should be considered first if you want to study in the USA?

A.The climate B. The scenery

C. The study condition D. The living condition

2.What is California like?

A.California is the best place to live in.

B. California is the worst place to live in.

C. California is a state with the largest city.

D. California is a state with different climates.

3. If you study in Middle America, you can probably _______.

A.find the best universities

B. feel the real character of the nation

C. meet the most famous professors there

D. face more difficulties

4. What can we conclude from the text?

A.All American famous universities lie in nice places.

B. Los Angeles is the most dangerous city in the USA.

C. Washington D.C. is the political centre of the USA.

D. It is always raining in the Midwest of the USA.

Scientists who try to predict earthquakes have gotten some new helpers recently—animals.

　　That’s right, animals. Scientists have begun to understand what farmers have known for thousands of years. Animals often seem to know in advance that an earthquake is coming, and they show their fear by acting in strange ways. Before a Chinese quake in 1975, snakes awoke from their winter sleep early only to freeze to death in the cold air. Cows broke their halters (缰绳) and tried to escape. Chickens refused to enter their cage. All of this unusual behavior, as well as physical changes in the earth, warned Chinese scientists of the coming quake. They moved people away from the danger zone and saved thousands of lives.

　　One task for scientists today is to learn exactly which types of animal behavior predict quakes. It’s not an easy job. First of all not every animal reacts to the danger of an earthquake. Just before a California quake in 1977, for example, an Arabian horse became very nervous and tried to break out of his enclosure. The Australian horse next to him, however, remained perfectly calm. It’s also difficult at times to tell the difference between normal animal restlessness and “earthquake nerves”. A zoo keeper once called earthquake researchers to say that his cougar had been acting strangely. It turned out that the cat had an upset stomach.

　　A second task for scientists is to find out exactly what kind of warnings the animals receive. They know that animals sense far more of the world than humans do. Many animals can see, hear, and smell things that people do not even notice. Some can sense tiny changes in air pressure, gravity, or the magnetism of Earth. This extra sense probably helps animals predict quakes.

　　A good example of this occurred with a group of dogs. They were shut in an area that was being shaken by a series of tiny earthquakes. (Several small quakes often come before or after a large one.) Before each quake a low booming sound was heard. Each boom caused the dogs to bark wildly. Then the dogs began to bark during a silent period. A scientist who was recording quakes looked at his machine. It was acting as though there were a loud noise too. The scientist realized that the dogs had reacted to a booming noise. They also sensed the tiny quake that followed it. The machine recorded both, though humans felt and heard nothing.

In this case there was a machine to monitor what the dogs were sensing. Many times, however, our machines record nothing extraordinary, even though animals know a quake is coming. The animals might be sensing something we measure but do not recognize as a warning. Discovering what animals sense, and learning how they know it is a danger signal, is a job for future scientists.
