In the United States alone, over 100 million cell-phones are thrown away each year. Cell-phones are part of a growing mountain of electronic waste like computers and personal digital assistants. The electronic waste stream is increasing three times faster than traditional garbage as a whole.
Electronic devices contain valuable metals such as gold and silver. A Swiss study reported that while the weight of electronic goods represented by precious metals was relatively small in comparison to total waste, the concentration (含量) of gold and other precious metals was higher in so-called e-waste than in naturally happening minerals.
Electronic wastes also contain many poisonous metals. Even when the machines are recycled and the harmful metals removed, the recycling process often is carried out in poor countries, in practically uncontrolled ways which allow many poisonous substances (物质)to escape into the environment.
Creating products out of materials creates much more waste material, up to 100 times more, than the material contained in the finished products. Consider again the cell-phone, and imagine the mines that produced those metals, the factories needed to make the box and packaging it came in. Many wastes produced in the producing process are harmful as well.
The U. S. Environmental Protection Agency notes that most waste is dangerous in that "the production, distribution, and use of products-as well as management of the resulting waste-all result in greenhouse gas release." Individuals can reduce their contribution by creating less waste at the start-for example, buying reusable products and recycling.
In many countries the concept of extended producer responsibility is being considered or has been put in place as an incentive (动机) for reducing waste. If producers are required to take back packaging they use to sell their products, would they reduce the packaging in the first place?
Governments' incentive to require producers to take responsibility for the packaging they produce is usually based on money. Why, they ask, should cities or towns be responsible for paying to deal with the bubble wrap (气泡垫) that encased your television?
From the governments' point of view, a primary goal of laws requiring extended(扩大的) producer responsibility is to transfer both the costs and the physical responsibility of waste management from the government and tax-payers back to the producers.
1.By mentioning the Swiss study, the author wants to tell us that ____.
A.the weight of e-goods is rather small
B.E-waste deserves to be made good use of
C.natural minerals contain more precious metals
D.the percentage of precious metals is heavy in e-waste
2.The responsibility of e-waste treatment should be extended _____.
A.from producers to governments B.from governments to producers
C.from individuals to distributors D.from distributors to governments
3.What is the passage mainly about?
A.The increase in e-waste. B.The creation of e-waste.
C.The seriousness of e-waste. D.The management of e-waste.

In the United States, people throw away 500 million plastic straws(吸管) every day! They are enough to circle the Earth twice. Unluckily, they are almost never recycled, because they are too small.
Now, plastic straws are the aim of environmental movements. Among them is Be Straw Free. A 23-year-old young man, Milo Cress, started the movement at the age of 16. “I noticed that whenever I ordered a drink at a restaurant, it would come with a straw,” he said. “This seems like a huge waste.”
Cress started by asking restaurants in his home city to stop providing straws if customers do not ask for one. Many of them agreed. Over the years, restaurants in the United States joined the movement. On average, they use 50-80 percent fewer plastic straws than they used to.
In other countries, there are similar movements. In the United Kingdom, many restaurants now use paper straws instead of plastic ones. The British government is planning to ban all plastic waste by 2042.
However, in China, it is very common that many restaurants still use plastic straws. Will you do something to change the situation? Everybody can make a difference to it!
1.Why do people almost never recycle plastic straws?

Millions of children in the United States ride safely to and from school on school buses each day. Although school buses are the safest way to take them to school, about 33 school-age children die in school bus-related(与巴士有关的) traffic accidents each year.
Most of those killed are five to seven years old. They are hit in the danger zone(区域) around the bus, either by a passing vehicle(车辆) or by the school bus itself. It is illegal(非法的) for a car to pass a bus with its red light flashing(闪耀).

Millions of children in the United States go to summer camps. Some go to play outdoors at traditional camps in the woods, in the mountains or on lakes. But families now have many choices of special camps. These can be in the middle of nature or a big city. Special camps offer young people the chance to learn about different subjects: anything from space exploration to business to medicine.
In technology camps, one subject that children can learn about is video game design. They learn how to use computer programs to create games of their own. One program that teaches video game design is called Cybercamps. Children can learn how to design their own virtual(实际上的) worlds to set their video game in. Then, they program their own rules and objects into the game.
Cybercamps also offers courses in robot building and Web design. A recent story in the Washington Post described how one child made a robot that could sing a song. Another made a robot that could follow a black line drawn on a piece of cardboard. Also, children can learn how to make Web sites. One child made a site for Pokemon, one of his favourite cartoon shows.

A.in the woods | B.in the mountains | C.on lakes | D.all above |
2.Special camps offer young people the chance to learn _______.

More than one-million school children in the United States have gone through a program called Reading Recovery(阅读恢复). The program is for six-year-olds with difficulties in learning to read.
Reading Recovery came to the United States in 1984. Education expert(专家) Marie Clay of New Zealand developed the program. A number of other countries also use this method. Programs are quite different from school. The Reading Recovery Council of North America says more than 25% of the United States public schools with first grades use the program.
The Reading Recovery method requires a specially trained reading teacher to work with children one at a time. The lessons take a half hour each school day, including reading, writing and the study of the letters of the alphabet(字母表).
Reading Recovery lessons take place for twelve to twenty weeks. During the lessons, the teacher looks for ways that the child seems to learn best. Then the teacher works to help the students develop these methods to solve problems in reading. The idea is for the students to continue to use these methods each time they read.
Reading Recovery students read many short books. Some of the books are written in a way similar to spoken language. Children also read and write stories or messages in their own words. The material gets harder with time.
The lessons end when the students’ reading ability is within the average level(平均水平) of the class. The Reading Recovery Council of North America says eighty percent of the students who finish the lessons can read and write within their class average. The leader of this program says more than ninety-nine percent of the Reading Recovery students in the schools passed the state reading examination.
Title: Reading Recovery
The 1. of the program | Help the children who have problems in learning to read. | |
Facts about the program | The time | It came to America in 1984. |

Requirements for the teachers | A. They must receive 3. and use reading, writing and the study of the letters of the alphabet. B. They must work out what is the best way for children. C. They help the students develop methods to solve problems in reading. | |
Requirements for the students | D. The students should make use of these methods in reading. E. They read some books 4. in spoken-language style. F. They use their own language to read and write stories or messages. | |
