   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.

   We often focus on building relationships with others but we forget the important first step: being friends of ourselves. 【小题1】. How can we have good relationships with others if we don’t even have good relationships with ourselves?

Your personal characters: You might have some personality traits that you don’t like. For example, you may be an introvert(内向的人)and you don’t like it; you wish you were an extrovert. Others might have better achievements than you, and no matter how hard you tried, it might seem impossible for you to match them. 【小题4】. Is there anything that resonates(产生共鸣)with you?

   In ancient Egypt, a shopkeeper discovered that he could attract customers to his shop simply by making changes to its environment. Modern businesses have been following his lead, with more tactics (策略).
One tactic involves where to display the goods. For example, stores place fruits and vegetables in the first section. They know that customers who buy the healthy food first will feel happy so that they will buy more junk food (垃圾食品) later in their trip. In department stores, the women’s shoe section is generally next to the women’s cosmetics (化妆品) section: while the shop assistant is going back to find the right size shoe, bored customers are likely to wander over and find some cosmetics they might want to try later.
Besides, businesses seek to appeal to customers’ senses. Stores notice that the smell of baked goods encourages shopping, so they make their own bread each morning and then fan the bread smell into the store throughout the day. Music sells goods, too. Researchers in Britain found that when French music was played, sales of French wines went up.
When it comes to the selling of houses, businesses also use highly rewarding tactics. They find that customers make decisions in the first few seconds upon walking in the door, and turn it into a business opportunity. A California builder designed the structure of its houses smartly. When entering the house, the customer would see the Pacific Ocean through the windows, and then the pool through an open stairway leading to the lower level. The instant view of water on both levels helped sell these $ 10 million houses.
【小题1】Why do stores usually display fruits and vegetables in the first section?
A.To save customers time.B.To show they are high quality foods.
C.To help sell junk food.D.To sell them at discount prices.
【小题2】According to Paragraph 3, which of the following encourages customers to buy?
A.Opening the store early in the morning.B.Displaying British wines next to French ones.
C.Inviting customers to play music.D.Filling the store with the smell of fresh bread.
【小题3】What is the California builder’s story intended to prove?
A.The house structure is a key factor customers consider.
B.The more costly the house is, the better it sells.
C.An ocean view is much to the customers’ taste.
D.A good first impression increases sales.
【小题4】What is the main purpose of the passage?
A.To explain how businesses turn people into their customers.
B.To introduce how businesses have grown from the past.
C.To report researches on customer behavior.
D.To show dishonest business practices.
