   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 taster 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 occurring 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 to escape into the environment.

Creating products out of raw 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(包装)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 instance,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 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.

【小题1】By mentioning the Swiss study,the author intends to tell us that .
A.the weight of e-goods is rather small
B.natural minerals contain more precious metals
C.E-waste deserves to be made good use of
D.the percentage of precious metals is heavy in e-waste
【小题2】The responsibility of c-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
【小题3】What docs the passage mainly talk 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.

   Communicating with your child's teacher is one way to help him succeed at school. But just how often should you contact the teacher,and what questions should you ask?How can you help your child succeed in school?

Jerry Parks,a social studies teacher is. to share his thoughts. Parks keeps in touch with parents through emails,class websites,and phone calls. " Parents who take an active interest in their children's work and school well-being are one of the biggest contributors to my students' success,"Parks says. Children of involved parents typically have higher self-esteem(自尊)and have fewer behavior problems in school. And students' grades usually improve when their parents become involved.

Parks suggests the top 6 ways parents can help their children succeed in school: first,make sure your child is at school every day possible. Missed work is generally more of a loss than made-up work is a gain;second,set a time and a place for your child to do homework. If he does not have homework,have him use the time to read;third,keep in touch with teachers,but don't do it too much. Most teachers appreciate parents caring enough to keep in touch a few times a term but do not appreciate parents expecting to contact on a regular basis. Besides,it seems appropriate to ask the teacher whether she thinks your child is giving his best effort in class and whether she has noticed any significant changes in your child's behavior or grades. More importantly,teach your child to build a character—it will improve social and academic skills more than anything else. Some things are simply wrong,and the world your child will grow up in will punish crimes,so give your child a head start. Last but not least,make time every day to talk with your child about the day's activities. Let him know you care,and really listen to what he has to say.
