3 . Melissa Poe was 9 years old when she began a campaign for a cleaner environment by writing a letter to the then President Bush. Through her own efforts, her letter was reproduced on over 250 donated billboards across the country.
The response to her request for help was so huge that Poe established Kids For A Cleaner Environment (Kids F.A.C.E.) in 1989. There are now 300,000 members of Kids FACE worldwide and is the world's largest youth environmental organization.
Poe has also asked the National Park Service to carry out a "Children's Forest" project in every national park. In 1992, she was invited as one of only six children in the world to speak at the Earth Summit in Brazil as part of the Voices of the Future Program. In 1993, she was given a Caring Award for her efforts by the Caring Institute.
Since the organization started, Kids F.A.C.E. members have distributed and planted over 1 million trees! Ongoing tree-planting projects include Kid's Yards – the creation of backyard wildlife habitats (栖息地) and now Kids F.A.C.E. is involved in the exciting Earth Odyssey, which is a great way to start helping.
"Starting the club turned out to be a way to help people get involved with the environment. Club members started doing things like recycling, picking up litter and planting trees as well as inviting other kids to join their club."
"We try to tell kids that it's not OK to be lazy," she explains. "You need to start being a responsible, environmentally friendly person now, right away, before you become a resource-sucking adult."

文章大意：这是一篇说明文。作者开门见山提出urban heat island（城市热岛效应）这一术语，然后分两段来分析造成这种状况的原因，比如基础设施的兴建、树木的减少、在夏天空调制冷设备的使用等都会造成气温的升高。
4 . On warm summer days with little or no wind, the air temperature in cities can be up to ten degrees higher than that of the surrounding countryside. This is a phenomenon commonly referred to as the “urban heat island” effect.
This phenomenon happens when pavement, buildings, and other infrastructure (基础设施) replace natural land cover. Large amounts of paved and dark colored surfaces—such as roofs, roads, and parking lots—absorb, rather than reflect, the sun’s heat, causing surface temperatures and overall ambient (周围的) air temperature to rise. Unlike soil, paved areas contribute to runoff, which means that as paved areas increase, the amount of water available for evaporation (蒸发) decreases. Moreover, urban areas have fewer trees and less natural vegetation which help to control the heat by providing shade and blocking solar radiation. The surfaces of leaves also provide water for evaporation which cools the air, further worsening the heat island effect.
In particular, during summer, more energy is required to cool the insides of building and for refrigeration, thereby creating additional heat output. This in turn leads to higher ambient air temperatures, which can also significantly increase the formation of urban smog in an area, degrading local air quality. Such a situation may directly affect public health with individuals more likely to suffer from heat exhaustion and the effects of asthma (哮喘).
1. The underlined part in Paragraph 2 means ________.
2. Which of the following is not a cause of the urban heat island effect?
3. The underlined word “degrading” most probably means ________.
4. The passage is mainly developed by ________.

文章大意：这是一篇应用文。文章介绍了英国一个使用生物甲烷气体的城镇，其使用情况、方法以及前景。
5 . A town in Oxfordshire has become the first in the UK to have biomethane (生物甲烷) gas from human waste piped to their homes for gas central heating and cooking.
Up to 200 families in Didcot now receive the gas via the national gas power system. Head of energy and technology at British Gas, Martin Orrill, said customers wouldn’t notice any difference as the gas is purified (提炼) to the highest standard and has no smell. The gas is produced at a sewage (污物) treatment works plant in Didcot.
The entire process takes only less than three weeks, with the sewage being collected and sent first to settlement tanks. The solid waste material is then fed into digesters, where anaerobic bacteria (厌氧菌) digest the sewage, with the aid of enzymes (酶) to speed up the process. The digestion process produces methane, which can be burned to drive machines to produce electricity, or can be purified and fed into the gas network and piped to homes and businesses. British Gas says supplying the gas rather than electricity is far more efficient since around two-thirds of the energy is lost in producing electricity.
Partners in the Didcot project, British Gas, Scotia Gas Networks, and Thames Water, all hope to expand the process to other towns, and other companies such as Ecotricity and United Utilities have also announced biomethane projects being planned. One of these projects, in Manchester, could be supplying 500 homes with biomethane by mid next year. Another British Gas project in Suffolk will provide gas from digestion of brewery wastes to around 235 families.
The Didcot project cost ￡2.5m and was influenced by promises of government aids aimed at encouraging companies to develop renewable technologies. An EU directive means the UK must ensure at least 15 percent of its energy is from renewable sources by 2020.
The UK produces about 1.73 million tons of sewage annually. If all sewage treatment works in the UK were fitted with the technology, they could supply gas for up to 350,000 families.
1. Which of the following is true of the biomethane gas?
2. What is the function of the enzymes?
3. According to British Gas, the biomethane gas had better be used _____.
4. The last three paragraphs mainly show that _____.

6 . Imagine one day, the water taps in your house stop running. You have to buy water from shops. And still there isn’t enough for everyone. Your mother has to save the family’s shower water to do other things. Would you be able to stand that kind of life?
Probably not. But that’s what kids in Yemen are experiencing. Experts said Yemen is going to be the first country in the world to run out of water. According to a report, the capital, Sanaa, will run out of drinking water as early as 2025.
Because of the shortage, the government often cuts the water supply. Hannan, an 18-year-old from Lahej, told the Times: “In a good week we’ll have a water supply all week. But then the following week there will be water only for a day or two.”
Hannan said only rich people have enough water to use. They can buy water from the shops or from the water truck. Private companies own the trucks. They travel around the city every day to sell water – at very high prices.
“A lot of people can’t afford it,” she said.
The average person in Yemen uses 100 to 200 cubic meters of water per year. That is far below the international water poverty line of 1,000 cubic meters.
The government is thinking of making use of seawater. But it will cost a lot and it may not happen soon enough to help the people of Yemen.
1. The purpose of the text is to _______.
2. The underlined word “that” in Paragraph 2 refers to _____.
3. Hannan described _____.
4. The Yemen Government _____.
5. We can infer from the text that _____.

8 . The huge Florida wetland known as the Everglades is a slow-moving river 80 kilometres wide but only a few centimeters deep. People call the Everglades a “river of grass” because sawgrass covers most of it. Sawgrass is not really grass. It is a plant that has leaves edged with tiny sharp teeth that can easily cut through clothes—and skin!
Travel in the Everglades is difficult. You cannot walk through shallow water because the sawgrass will cut you. The water is too shallow for regular boats. So, we use an airboat. An airboat is a flat, open boat. Like an airplane, it has a big propeller to move it. The propeller is fixed on the rear of the boat. It makes a tremendous noise, but it does the job. The boat skims along the water’s surface. Although we can still get lost in an airboat, at least we are above the alligators(短吻鳄).
While hundreds of different kinds of animals live in the Everglades, the most famous is surely the alligator. Once endangered, alligators are now protected within Everglades National Park. Visitors are likely to see them both on land and in water.
For a long time, dangers have threatened the Everglades. Around 1900, some people felt this precious wetland should be drained (排干). They said it was just a big swamp and not good for anything. In the 1920s, there was a land boom in Florida. People wanted to build homes everywhere, including in the Everglades. They built canals, levees (防洪堤), and other water systems that stopped the rivers flowing into the Everglades. Factories were built near rivers that flowed into the wetland. These factories dumped poisonous waste that damaged the Everglades ecosystem.
People are now working to preserve the Everglades National Park for the future. Right now, one big problem is the paperbark tree. This tree is an invader from Australia.
Paperbark trees soak up a lot of water. In the early 1900s, people brought them to Florida because they thought they would help drain the Everglades. However, the invaders adapted too well. Paperbark trees have taken over hundreds of thousands of acres of the Everglades and killed other trees. Scientists are cutting down these invaders or spraying them with herbicides (除草剂) to kill them.
1. Which helps to explain why it is difficult to travel in Everglades?
2. Why do people use airboats instead of normal boats?
3. The following measures were taken to drain the Everglades except that people______.
4. The underlined word "invader" probably means something______.

9 . C
Does this mean we should stop bathing? No, say the scientists, but we should put all pollution into perspective. Activities at home such as the burning of coal, cooking oil, or even candles release carbon monoxide and particulates such as cigarette ashes which have been proven as harmful to health as working or living near heavy traffic. New tugs, bedding, and even clothing give off that “new smell,” which is a sure sign of chemicals. In the office, newly applied paint, newly purchased telephones and other telecommunications equipment, and computers release polluting chemicals, too. As offices and homes often have inadequate ventilation (通风), these chemicals can build up to become health problems. Their poisonous effects are only now being slowly recognized.
These facts suggest that, at a minimum, proper airing of newly purchased goods with an obvious chemical smell is a wise warning. Home and office windows should be opened during good weather. Even one’s car needs to be ventilated as well while in the garage.
We need further research to understand better other potential health dangers, too. For example, the effects of overcrowding of schools (carbon dioxide build-up), the factory work environment (an endless list of potentially dangerous substances), and even home heating and cooling (the air conditioner may be our enemies, not our friends) have only recently started to come to light. Until we understand the effects of our new technological environment better, we can only hope that “there is no place like home.”
1. What is the main idea of the first paragraph?
2. In Paragraph 2, the underlined sentence means that .
3. What ihe purpose of the passage?
Apparently, we are safe neither at home nor in the business office. We use water in both places, but the research shows that chemicals added to our local water supply to kill harmful bacteria can have unwanted side effects. These chemicals can cause potential harm through drinking and in seemingly harmless activities as cleaning one’s house. They are released(set free)from water by daily actions like water running out of tap, spraying from garden pipes，or splashing in dishwashers and washing machines. As the water is moving, these chemicals are released into the air and then breathed in. Once inside our bodies, they start to affect our health.
Does this mean we should stop bathing? No, say the scientists, but we should put all pollution into perspective. Activities at home such as the burning of coal, cooking oil, or even candles release carbon monoxide and particulates such as cigarette ashes which have been proven as harmful to health as working or living near heavy traffic.
