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.
【小题1】Which of the following about the FCX is not true?

A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below l6℃. Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover，these areas would reflect more heat into the atmosphere，warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns，potentially causing certain natural disasters all over the world.
In the past hundred years，humans have begun destroying rainforests in search of three major resources（资源）：land for crops，wood for paper and other products，land for raising farm animals. This action affects the environment as a whole. For example，a lot of carbon dioxide in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.
There are two main reasons for this. Firstly，when people cut down trees，generally they can only use the land for a year or two. Secondly，cutting large sections of rainforests may provide a good supply of wood right now，but in the long run it actually reduces the world’s wood supply.
Rainforests are often called the world’s drug store. More than 25％ of the medicines we use today come from plants in rainforests. However，fewer than l％of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests.

A new study shows one of the largest glaciers(冰川) in Greenland is becoming smaller and speeding to the sea faster than scientists expected. If it continues, Greenland itself could become much smaller during this century and global seas could rise as much as 3 feet.
The rates of change that we’re noticing are much higher than expected. If these rates continue, it is not likely that Greenland could shrink by several tens of percent this century. However, it’s not known how quickly this coastal response of the Greenland ice sheet melting will have an effect on the vast inland ice.
Greenland is the world’s largest island, covering area more than three times the size of Texas. Some 81 percent of it is covered by ice, and there are many glaciers. Glaciers are like slow-moving rivers of ice. Where a glacier meets the sea, its weight keeps it firmly resting on the bottom. A glacier’s front is the point where the water is deep enough that the glacier floats.
Since the 1970s, the front of Helheim stayed in the same place. Then it began melting rapidly, moving back 4.5 miles from 2001 through this past summer. It has also grown thinner, from top to bottom, by more than 130 feet since 2001. And over these past years, its trip to the sea has sped up from about 70 feet per day to nearly 110.
The melting is driven by a warmer climate. Temperatures in Greenland have risen more than five degrees Fahrenheit(华氏温度) in the last ten years. Since most of Greenland’s ice is on land, seas will rise as the ice melts. If all Greenland’s ice sheet melted, oceans would be 15-20 feet higher. Nobody expects that to happen any time soon.
【小题1】What can we know about the glaciers according to the passage?

A few years ago I asked my children’s governess, Julia Vassilyevna, to come into my study.
“ Sit down, Julia Vassilyevna,” I said.“Let’s settle our accounts. Although you most likely need some money, you stand on ceremony and won’t ask for it yourself. Now then, we agree on thirty rubles a month…”
“ Forty.”
“ No, thirty. I made a note of it. I always pay the governess thirty. Now then, you’ve been here two months, so…”
“ Two months and five days.”
“ Exactly two months. I made a specific note of it. That means you have sixty rubles coming to you. Subtract nine Sundays… you know you didn’t work with Kolya on Sundays, you only took walks. And three holidays…”
Julia Vassilyevna flushed a deep red and picked at the flounce of her dress, but--- not a word.
“ Three holidays, therefore take off twelve rubles. Four days Kolya was sick and there were no lessons, as you were occupied only with Vanya. Three days you had a toothache and my wife gave you permission not to work after lunch. Twelve and seven---nineteen. Subtract…that leaves…hmm…forty-one rubles. Correct?”
Julia Vassilyena’s left eye reddened and filled with moisture. Her chin trembled; she coughed nervously and blew her nose, but---not a word.
“ Around New Year’s you broke a teacup and saucer: take off two rubles. The cup cost more, it was an heirloom, but---let it go. When didn’t I take a loss? Then, due to your neglect, Kolya climbed a tree and tore his jacket: take off ten. Also due to your heedlessness the maid stole Vanya’s shoes. You ought to watch everything! You get paid for it. So, that means five more rubles off. The tenth of January I gave you ten rubles…”
“ You didn’t ” whispered Julia Vassilyevna.
“ But I made a note of it.”
“ Well…all right.”
“ Take twenty-seven from forty-one ---that leaves fourteen.”
Both eyes filled with tears. Perspiration appeared on the thin, pretty little nose. Poor girl!
“ Only once was I given any money,” she said in a trembling voice, “ and that was by your wife. Three rubles, nothing more.”
“ Really? You see now, and I didn’t make a note of it! Take three from fourteen… leaves eleven. Here’s your money, my dear. Three , three, three, one and one. Here it is!”
I handed her eleven rubles. She took them and with trembling fingers stuffed them into her pocket.
“ Merci,” she whispered.
I jumped up and started pacing the room. I was overcome with anger.
“ For what, this ---‘merci’?” I asked.
“ For the money.”
“ But you know I’ve cheated you, God’s sake---robbed you! I have actually stolen from you! Why this ‘merci’?”
“ In my other places they didn’t give me anything at all.”
“ They didn’t give you anything? No wonder! I played a little joke on you, a cruel lesson, just to teach you … I’m going to give you the entire eighty rubles! Here they are in an envelope all ready for you… Is it really possible to be so spineless? Why don’t you protest? Why be silent? Is it possible in this world to be without teeth and claws--- to be such a nincompoop?”
She smiled crookedly and I read in her expression: “ It is possible.”
I asked her pardon for the cruel lesson and , to her great surprise, gave her the eighty rubles. She murmured her litter “merci” several times and went out. I looked after her and thought: “How easy it is to crush the weak in this world!”

A new generation addiction is quickly spreading all over the world. Weboholism（醉心于网络）, a twentieth century disease, affects people from different ages. They surf the net, use e-mail and speak in chat rooms. They spend many hours on the computer, and it becomes a compulsive habit. They cannot stop, and it affects their lives.
Ten years ago, no one thought that using computers could become compulsive（强迫性的）behavior that could affect the social and physical life of computer users. This obsessive behavior has affected teenagers and college students. They are likely to log on computers and spend long hours at different websites.
They become hooked on computers and gradually their social and school life is affected by this situation. They spend all free time surfing and don’t concentrate on homework, so this addiction influences their grades and success at schools. Because they can find everything on the websites, they hang out there. Moreover, this addiction to websites influences their social life.
They spend more time in front of computers than with their friends. The relation with their friends changes. The virtual（虚拟的）life becomes more important than their real life. They have a new language that they speak in the chat rooms and it causes cultural changes in society.
Because of the change in their behavior, they begin to isolate（孤立 themselves from the society and live with their virtual friends. They share their emotions and feelings with friends who they have never met in their life. Although they feel confident on the computer, they are not confident with real live friends they have known all their life. It is a problem for the future. This addictive behavior is beginning to affect the whole world.
