1 . It is reported that bags are getting bigger all the time，and that there are more bags per person on the street today than at any other time in history．If this is true，possible explanations could include the wide use of small electric and electronic devices，a reading-material explosion，a popular interest toward tight or pocket less clothing，or cheap bagmaking labor overseas.
But，much as nature finds ways—such as disease—to control overpopulation，city life has thrown up impediments(障碍) to bags．To enter many public buildings，such as theatres and railway stations，you must go through a search or go bagless．The city has countless bag rules．It is hard to keep them all straight，and you're never sure，when leaving home for the day，whether it might be a bad idea to bring one along．
Last week，the New York Public Library got in the game．Students，researchers，writers，historians，and anyone else who has got used over the years to treating the vast Rose Main Reading Room as an office or a reading room came up against a new rule．You are no longer allowed to bring a bag larger than eleven inches by fourteen inches into the library．If you walk in with one，you must leave it at the coat check．You may keep its contents with you，however，and the library provides big clear plastic bags for them．You return them when you come back for your own bag．
What the library is trying to prevent，in this case，is people taking things out，rather than bringing things in．A librarian said on the second day，”It’s a big change for people who used to come and bring in half their flats．The people who use the library responsibly will continue to do so．The people who steal will continue to get away with it，if they really want to．”

2 . Earth Day is on April 22nd. People say thanks to the Earth and learn ways to keep the Earth safe and clean. But saving the Earth is not just for grow-ups. Kids are also taking an active part in it.
The American writer and filmmaker Lynne made a film called Young Voices for the Planet. It lists a lot of stories about different kids who help to keep our environment clean.
Team Marine, USA group of students at Santa Monica High School started an organization called Team Marine. They tell people why plastic bags are bad for sea animals and environment. In 2011, they successfully made lawmakers (立法者) in their city stop people using plastic bags.
Felix, 15, Germany In 2007, a 9-year-old boy, Felix, started a club，Plant for the Planet. It encourages children around the world to plant trees in their own countries. Felix helped plant 25 million trees in Germany and 120 million trees worldwide.
Alec, 17, US When he was 12, Alec set up Kids VS Global (全球的) Warming. It teaches kids about weather change and ways to stop the world getting warmer and warmer. Alec travels widely to encourage people to help stop global warming. He has given more than 70 talks across the country.
Olivia, 13, US When Olivia was 11, she heard about the 2010 oil spill (漏油) in the Gulf of Mexico. She painted 500 pictures of birds to raise money for the clean-up. She raised more than $200,000 to protect (保护) birds and other wild animals.

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."

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 ________.
| A．Due to dark colored roads, urban areas are becoming hotter each year |
| B．Dark colored surfaces reflect the sun’s heat, causing air temperatures to rise |
| C．Because urban surfaces absorb heat, air and surface temperatures increase |
| D．Rising ambient air temperatures lead to urban surfaces absorbing more heat |
| A．The lack of trees |
| B．The demand for refrigeration |
| C．The blocking of solar radiation |
| D．The construction of infrastructure. |
| A．ignoring | B．improving |

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?

| B．To help get rid of anaerobic bacteria. |
| C．To help purify the biomethane. |
| D．To speed up the digestion process. |
| A．as the power for the vehicles |
| B．for the heating and cooking |
| C．to produce the electricity |
| D．to drive a variety of machines |
| A．UK government supports the biome thane projects |
| B．the biome thane projects are very costly |
| C．the biome thane projects still face many barriers |
| D．the biome thane projects are promising |

6 . Think about the different ways that people use the wind. You can use it to fly a kite or to sail a boat. Wind is one of our cleanest and richest power sources, as well as one of the oldest. Evidence shows that windmills (风车) began to be used in ancient Iran back in the 7th century BC. They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power.
For many centuries, people used windmills to grind (磨碎) wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote (偏远的) areas began to use them to produce electricity. This allowed them to have electric lights and radio. However, by the 1940s when electricity was available (可利用的) to people in almost all areas of the United States, windmills were seldom used.
During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means higher costs. Today, there is a global movement to supply more and more of our electricity through the use of wind.

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.

Many Chinese cities now face the same sort of problem with air pollution that London faced 40 or 50 years ago. However, this problem is more difficult for Chinese cities to solve. One reason is that more of the pollution comes from the factories, rather than from coal burnt in people’s houses. If these factories were closed, this would harm the economy and lots of people would lose their jobs. Another reason is that changing from coal to cleaner fuel（燃料）, like gas, is quite expensive.
However, the air in many Chinese cities is becoming cleaner and cleaner, as the government and people pay more and more attention to cutting down pollution. As a result, there are fewer “pea-soupers” in Beijing than there used to be.

The first No Car Day in China was in Chengdu in 2001．Other cities, including Taipai, Shanghai and Wuhan, also support the day.
In Beijing, more and more people are joining the campaign（运动）. It asks drivers to leave their cars at home for one day each month and walk or ride a bike to work. It also calls on Beijingers not to use cars on June 5 （World Environment Day）. The slogan for the day is, “If we drive for one less day, we can have one more nice day.”
So far, more than 200,000 drivers have shown their support. “We can’t control the weather, but we can choose not to drive,” said Wu Zonghua, a car club chairman. Beijing is trying to have 238 blue sky days this year. In the first quarter of 2012, Beijing only had 52 blue sky days. This was 11 days less than the number for the same period the year before. Much of the dust（灰尘） comes from the desert, but cars cause most of the air pollution. We must do more for No Car Day.
