How would you like an easy way to earn 2,500 dollars? All you have to do is to sit around and wait for your meals．There’s catch, however．You have to stay in a chicken cage with a stranger for a whole week．There are no books or television or radio for amusement．You can’t leave until the week is up．And a camera will be recording your every move．
Two people actually took the job．The idea came from Rob Thompson, a video artist．He wanted to make a film about the way animals are treated．His goal was to raise people’s awareness of the living conditions of animals that are raised for food．He decided to pay $ 5000 out of his own savings to two people who were willing to lie like chicken for a week．
To Rob’s surprise, quite a few people answered his advertisement．He had interviews and selected Eric, a 24-year-old restaurant worker, and Pam, a 27-year-old chemist．The plan was for them to spend seven days together in a chicken cage that was six feet long and three feet wide．A camera would record their experience, which would take place in an art museum．
The week was long and difficult．They slept on a hard wooden floor．They couldn’t stand up without banging（重击）their heads．They ate vegetarian mash（土豆泥）and drank water from a garden hosepipe（水龙头软管）．Their only privacy was a toilet surrounded by a curtain．There were no sinks, mirrors, or toothbrushes in the cage．Their only inspiration was the two framed checks that hung on the wall outside the cage．Visitors who came here were warned, “Do not food the humans．”
Finally it was over, Pam and Eric emerged from their cage．They had survived the week, and they each had a $2,500 check in their hands．When Rob Thompson opened the cage, Eric came out, changed into clean clothes, and ate a chocolate bar right away．“It’s great to be able to stand up,” he said．Pam just changed her clothes and left．After a week of visitors and reporters watching her, she didn’t want to talk to anyone．

Weather changes when the temperature and the amount of water in the atmosphere change. We can see and feel water coming from the atmosphere when we have rain. But the water must somehow get back to the atmosphere. Meteorologists call this the water cycle.
There are many stages in the water cycle. Rain falls when water vapour in clouds condenses(凝结). Drops of water form and fall to the ground. The water soaks into the ground and feeds streams and rivers. A lot of rain falls into the sea. The heat of the sun evaporates some of the water in the ground and in the rivers, lakes, and the sea. It changes the liquid water into water vapour. The vapour rises onto the air. Water vapour is normally invisible. On a very damp or humid day, however, you can sometimes see water vapour rising from a puddle(水坑) or pond in a mist(薄雾) above the water. Water vapour also gets into the air from living things. Trees and other plants take in water through their roots and give off water vapour from their leaves. People and land animals drink water and breathe out water vapour. In all these ways the water returns to the air. There it gathers to form clouds and condenses to form rain. The rain falls to earth, and the cycle starts again. It continues even if snow or hail(冰雹) fall instead because both eventually melt to form water. The amount of water vapour in the air depends on the temperature. The air is more moist(潮湿) in the tropics(热带) than in the cold polar regions.
1. What is the main idea of the passage?
A. Water cycle. B. Water vapour.
C. How rain forms. D. Water, vapour, rain.
2. How many ways of the water returning to the air are discussed in the text?
A. Two. B. Three. C. Four. D. Five.
3. Whether water vapour can be seen or not depends on _______.
A. how much water is evaporated B. how good your eyes are
C. in which way water is evaporated D. climate or weather
4. From the passage we get to know _______.
A. there is more water vapour in the air in the tropics than in cold polar regions
B. there is more water vapour in the air in cold polar region than in the tropics
C. it gets more rain in the tropics than in cold polar regions because there is less vapour
D. the amount of water vapour in the air depends on how often it rains

GU Zhaodi, 60, had taken water for granted for years. In fact, no one in the beautiful lake city of Wuxi, Jiangsu Province had bothered to spare a thought on water.
But all that changed dramatically overnight last month when taps in the city ran dry. Due to a blue-green algae(藻类) outbreak in Taihu Lake, China’s third largest freshwater lake and the source of drinking water for 4 million Wuxi residents(居民), water from the city’s taps became dark and smelly.
“I can’t believe there is no water for drinking, let alone cooking and washing,”said Ｇu.
The lake was blanketed with the algae, giving off a strong smell of rotting meat. A stone thrown into it took a long time to sink. Experts said that algae usually boom because of hot water and rich chemicals like phosphor(磷)in the water.
“High temperature and a lack of rain in the past few months helped the growth of algae,”said Zhang Lijun, an official from the State Environment Protection Administration. “However, pollution from human activity should be most blamed for the disaster.”
Taihu Lake is surrounded by many small factories, whichsprang up in the 1980s.Inthe 1990s,many foreign-funded(外资的) companies joined in. The industries prospered(繁荣)，Wuxi has grown into one of the wealthiest cities in East China.
But that came at the price of pollution. The lake was treated like a waste dump(垃圾堆)，with factories emptying industrial waste and untreated sewage(污水)into it.
Although, after the government's effort, life in the city has gone back to normal, the one-week crisis（危机）rang a bell for the government and local people.“It's time to rebuild the beauty of nature, or our lives will be at risk,”said Gu.
“A safe environment comes first. Economic growth will be nothing without fresh water to drink and clean air to breathe.” said China Daily.
【小题1】The following can help the blue green algae grow______
| A．high water temperature |
| B．rich chemicals in the water |
| C．a lack of rain |
| D．plentiful water and sunshine |
| A．The one-week disaster has made the local people realize the importance of building a beautiful city. |
| B．It is human activity rather than the algae that is to blame for the water pollution. |
| C．Only when the environment is safe and friendly can man live a better and healthier life. |
| D．Environment should be taken into consideration first if a city plans to develop its economic. |
| A．Who is to blame, man or algae? |
| B．Water turned off |

“Why should I care about the environment?” some people ask. There is a very simple reason: We live on the earth, and it is the only place we can live on right now, as we cannot live in space yet. If we treat the earth like a garbage dump, it will become dirty and unlivable. If we treat it well by being eco-conscious, the earth will stay clean and suitable for living, for ourselves and for our children.
What is “being eco-conscious”?
Being eco-conscious means being aware of your actions, and what you do to the environment. For example, you might think, “Using hairspray is great for fixing my hair.” However, if you are eco-conscious, you would ask, “Does this hairspray have CFCs in it? Could I be destroying the earth by using hairspray?”
How can I be eco-conscious?
You can find many simple ways to help the environment in your everyday life.
When you go shopping, bring a bag or a basket with you. Please try not to use plastic bags as much as you can.
You can go to work by bike or on foot if it is not far from your home.
You can put your rubbish into different bags, which makes it convenient for recycling.
You can eat less chewing gum.
You can use your own chopsticks instead of the disposable ones in your company or in restaurants.
You can put batteries in a special box instead of in garbage bins.
You can use the water which has been used for washing vegetables or fruits to clean the floor and the toilet or to water your garden.
You can turn off the decorative lights in your room when watching TV.
You can turn down your air conditioner by one degree, as this will cause a 10% reduction in energy use.
You can use recycled paper. Every ton of recycled office paper saves 380 gallons of oil. You can also use recycled glass instead of glass made from raw materials. This will reduce the related air pollution by 20%, and the related water pollution by 50%.
Please believe that. If you do a little, it will make a big difference.

We use an average of 158 liters of water a day in Britain, for which we pay a bargain price of 28p a liter, but much of this is just cash down the drain, according to water companies.
Most are campaigning to cut the amount we use. And the frontline weapon in their campaign is the water meter (计量器). They want us all to have one and one company is seeking powers to make this compulsory.
The Government is anxious for us to use less water, too. Elliot Morley, the Environment Minister, says he is impressed by the savings when a meter is installed. In most homes, consumption drops by 20 percent.
He also thinks consumers get a good deal from meters. He said, “Most people would find that they would either be exactly the same or better off with water meters and it is a fairer way of paying for water.”
At present, only 25% of households have meters and most of those are in East Anglia. They are installed by water companies, and households then have about ￡43 added to each bill to cover the cost of installing and reading the meter.
Barrie Clarke, a spokesman for Water UK, said, “We want everyone to be more water wise—to think about the amount of water they use. But with our climate change and different weather patterns, over time it will make economic and environmental sense to think how we use water. This may mean meters.”
Mr. Clarke believes the easiest way to save water is to use less in the garden. In one hour, a sprinkler uses the same amount of water as the average family of four uses in a day—about 632 liters. He said that gardeners should water in the evening so that it dose not evaporate in the heat of the day and that every household should have a water butt to collect rainwater for use in the garden.
1.Which of the following is NOT the advantage of installing water meters?
A．Water consumption drops.
B．It’s fairer to pay for water.
C．They’re installed for free.
D．People are more water wise.
2.The passage implies that ________.
A．water meters are welcome by British people
B．people will be better off with water meters
C．everyone has become wiser to use water now
D．saving water is both good to economy and environment
3.How many liters of water does an average family of four use in a day after installing a meter in Britain?
A．about 126 liters B．about 158 liters
C．about 506 liters D．about 632 liters
4.The underlined word “evaporate” in the last paragraph means _________.
A．change into steam and disappears
B．absorb the heat of the day
C．sink into the soil
D．turn into ice
5.According to Mr. Clarke, some good ways to save water are as follows EXCEPT ________.
A．using less on the garden
B．using a sprinkler
C．watering in the evening
D．gathering rainfall for garden use
