Hu Li's heart sank due to the color of the air.Driving 140 kilometers from Tianjin City to Beijing last week，she held her breath as the air became a charcoal grey haze(炭灰色的阴霾)．The 39yearold businesswoman has lived in Beijing for a decade，and this past month，she said，brought the worst air pollution she has ever seen.It gave her husband a cough and left her sevenyearold daughter housebound(足不出户)．“My husband as well as I is working here，so we have no choice，” she said.“But if we had a choice，we'd like to escape from Beijing.”
The extended heavy pollution over the last month，which caused punishment in return for a day last week－called the “airpocalypse” by internet users－ has largely changed the way that Chinese think about the country's air.On one day，pollution levels were 30 times higher than levels considered safe by the World Health Organization (WHO)．Flights were cancelled.Roads were closed.One hospital in east Beijing reported they had treated more than 900 children for breathing issues.Bloomberg found that for most of January，Beijing's air was worse than that of an airport smoking area.
The smog's(烟雾) most threatening aspect is its high concentration(浓度) of PM 2.5 － particulate matter that is small enough to breathe deep into the lungs and enter the bloodstream，causing breathing infections，lung cancer and possibly damaging children's development.The WHO has estimated that outdoor air pollution accounts for two million deaths per year，65% of them in Asia.Which conclusion can we draw from the first paragraph?

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.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 |
The first sentence probably refers to ________.

| 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 |
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. |
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. |
Death Valley is a land of beautiful yet dangerous extremes. Death Valley can be dangerously cold during the winter months. Storms in the mountains can produce sudden flooding on the floor of the Valley.
The air temperature during the summer has been as high as fifty- seven degrees Celsius. The sun can heat the ground so that the temperature of the rocks and soil can be as high as seventy -four degrees Celsius.
Death Valley contains evidence of several ancient volcanoes that caused huge explosions. Evidence of one of these explosions is called Ubehebe Crater. The explosion left a huge hole in the ground almost a kilometer and a half wide. In many areas of Death Valley it is easy to see where the ground has been pushed up violently by movement deep in the Earth. This movement has created unusual and beautiful rock formations. Some are red. Others are dark brown, gray, yellow or black.
The area was named by a woman in 1849. Thousands of people from other parts of the ountry traveled Lo the gold mining areas in California. They were in a hurry to get there before other people did. One group trying to reach California decided to take a path called the Old Spanish Trail. By December they had reached Death Valley. They did not have to survive the terrible heat of summer, hut there was still an extreme lack of water. There were few plants for their work animals to eat.
The people could not find a pass through the call mountains to the west of the Valley. Slowly, they began co suffer from a lack of food. To survive, they killed their work animals for food and began to walk out of the Valley. As they left, one woman looked back and said, “Good -bye, death valley.” The name has never been changed.
Almost everyone who visits Death Valley visits a huge house called Scotty' s Castle. The building design is Spanish, with high thick walls to provide protection from the fierce heat.

When you get in your car, you reach for it. When you're at work, you take a break to have a moment alone with it. When you get into a lift, you play with it.
Cigarette? Cup of coffee? No, it's the third most addictive thing in modem life, the cell phone. And experts say it is becoming more difficult for many people to curb their longing to hug it more tightly than most of their personal relationships.
The costs are becoming more and more evident, and I don't mean just the monthly bill. Dr.Chris Knippers, a counselor at the Betty ford Center in Southern California, reports that the overuse of cell phones has become a social problem not much different from other harmful addictions: a barrier to one-on -one personal contact, and an escape from reality. Sounds extreme, but we' ve all witnessed the evidence: The person at a restaurant who talks on the phone through an entire meal, ignoring his kids around the table; the woman who talks on the phone in the car, ignoring her husband; the teen who texts messages all the way home from school, avoiding contact with kids all around him. Jim Williams, an industrial sociologist based in Massachusetts, notes that cell - phone addiction is part of a set of symptoms in a widening gulf of personal separation. He points to a study by Duke University researchers that found one-quarter of Americans say they have no one to discuss their most important personal business with. Despite the growing use of phones, e - mail and instant messaging, in other words, Williams says studies show that we don't have as many friends as our parents. “Just as more information has led to less wisdom, more acquaintances via the Internet and cell phones have produced fewer friends,” he says.
If the cell phone has truly had these effects, it's because it has become very widespread. Consider that in 1987, there were only l million cell phones in use. Today, something like 300 million Americans carry them. They far outnumber wired phones in the United States.From the first two paragraphs, we can know ．
| A．cell phones have become as addictive as cigarettes |
| B．cell phone addiction is good for building personal relationships |
| C．people are longing to have their own cell phones |
| D．cell phones are the same as cigarettes |
Cell phone addiction has caused the following effects EXCEPT.

| C．an escape from reality | D．a serious illness |
The underlined word "curb" in Paragraph 2 means “．”
| A．ignore | B．control | C．develop | D．rescue |
The example of a woman talking on the phone in the car supports the idea that.
| A．women Use cell phones more often than men |
| B．talking on the phone while driving is dangerous |
| C．cell phones do not necessarily bring people together |
| D．cell phones make one - on - one personal contact easy |
Which of the following is the best title for the passage?
| A．Cell phones Are the New Cigarettes |
| B．Cell phones Are Harmful to the Society |
| C．The New Report about the Cell phone |
| D．The Disadvantages of the Cell phone |
Not long ago the movie 2012 came into screen. The people were threatened by those scenes of destroying flood, severe earthquake, terrifying hurricane and constructions representing human civilization being destroyed and even swallowed by disaster. Luckily, they are just the director’s imagination, but the present situation is not heading a positive direction, either.
Take my own experience in Alaska as an example. Once I took a trip to the glacier. Along the way there stood signposts marking the snow lines of different years. They started from the foot of the mountain, but it was at the top when I finally saw melting glaciers(融化的冰川). My heart ached seeing the beautiful blue ice melting at every second.
Sad but true, they are the effects of global warming and the result of our human impact. Furthermore, each year the rising sea level will kill 56 million people, and that's about the population of the en tire Italy. According to studies, if the temperature keeps on rising like this, by the year 2050, some islands and coastal cities including New York, Shanghai, Tokyo and Sydney will be drowned in water.
Our fortune is in our own hands. It depends on us to shape our future, to reduce future human impact and find ways to form a peaceful relationship with our environment. Therefore, it's time for actions to be taken right now. Contribute a little to energy saving by using more efficient light bulbs and less hot water. Let recycle become our habit by thinking twice before throwing something away. Let us take public transportation as our first choice when going to a certain place. It might cost more time for now, but it' s to the benefit of a permanent future. Take care of every tree and grass around us by watering them or simply just avoid destroying them．
In a word, small drops of water make a big ocean. The earth does not belong to us. On the contrary, we belong to the earth. Please bear in mind that the earth is our home.

Some Chinese new - rich like eating shark fin soup because they think it shows their class. However, for the Chinese NBA idol Yao Ming, doing so is unacceptable as the practice has led to the overfishing of sharks.
When Yao and his wife Ye Li got married in 2007, they publicly announced that they would not allow shark fin soup to be served at their wedding banquet.
Actually, Yao had been saying no to shark fins since 2006, when he was appointed as the Goodwill Ambassador for wild life protection.
Now, the 226 - cm big guy is resorting to his personal influence to encourage more to say no to eating the soup and to raise awareness of protecting animals. “Sharks are friends of human beings. They are not our food,” Yao said.
Other celebrity athletes like Olympic champions. Li Ning and Kong Linghui are following on the heels of Yao, throwing themselves into serving the public as Goodwill Ambassadors for wild animal rescue. Recent reports about Yao’s retirement have saddened tens of thousands of basketball fans both at home and abroad. Yet Yao's influence goes far beyond the basketball courts.
Yao has engaged himself in charity and public welfare services for quite a while. When the devastating 8.0 －magnitude earthquake hit Wenchuan in southwest China in 2008 , Yao donated 2 million yuan. “When I was a little boy, my parents and teachers told me to help others and to be a good man,” Yao recalled. “But I could nor donate then because I had not much pocket money. After I moved to Houston, I got involved in quite a number of community service activities and I felt a strong sense of achievement when I got people together,”Yao said.
Like Yao, newly crowned French Open champion Li Na has showed her willingness to donate. Li gave 480,000 yuan of her prize money from the open, plus 20,000 yuan from her own pocket, to a local nursing home in her hometown.
