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.

   Searching for airfares often seems like a game that passengers are bound to lose.

Prices change from day to day, even minute to minute. Looking through various websites for the best deal can be a big challenge. Even when you do book, there’s no guarantee that you are going to get the best price.

“You just don’t know when to pull the trigger. It’s not like buying anything else I can think of,” said George Hobica, founder of Airfarewatchdog. com.

Harriet Levy paid $ 179 for a recent round-trip flight on American Airlines between New York and Fort Lauderdale, Florida. Sitting just one row behind her, Shirley Harrison paid $ 215. A few rows back, Ellis and Dianne Traub paid $ 317 each. There were at least 12 fares on the flight, ranging from $ 169 to $ 360.

“There’s no reason for it,” Harrison said.

Fares can vary significantly in just a few hours. One Delta flight from New York to Los Angeles jumped from $ 755 to $ 1,143 from a Friday to Saturday in late April, and then fell to $ 718 on Sunday.

The flight was one of a dozen the Associated Press（美国联合通讯社）followed over three months for a vacation between July 16 and 22. The number one finding: avoid booking tickets on weekends. It’s the most expensive time to buy.

There’s no way to guarantee the best fare. But before booking, travelers should pay attention to this additional advice:

● Book on Tuesday, Wednesday and Thursday. That’s when airlines most often offer sales.

● Buy in advance, but not too early. The best time is four to six weeks before traveling. In general, prices for any given flight are the highest when tickets are booked eight to ten weeks and two to three weeks in advance.

● Make use of social media. Airlines are giving more benefits like exclusive（专有的）sales to travelers who interact（交流）with them on Twitter and Facebook. Those specials are often gone within hours.

● The so-called discount airlines — JetBlue, Air-Tran, Southwest and Frontier — adjust their fares less frequently than other airlines, so you can feel more confident that the price will stay the same. But their prices aren’t always the lowest. Researching multiple airlines’ fares is the only way to get a good deal.

Four Ways to Make Your Shoes Feel Better

According to the American Podiatric Medical Association, the vast majority of people experience foot pain at some point in their lives. The reason for most foot pain is that shoes fit poorly or force the feet into unnatural shapes. 【小题1】 Aside from carefully selecting the right shoes, there are some easy measures you can take to keep your feet from being painful.

1. Stretching Your Shoes

If your feet are rubbing against your shoes this could indicate that you need more width, length or both. However, sometimes going to the next larger size is not a choice, as the next size may be too large. 【小题2】.

2. Using Shoe Inserts (插入物)

Both doctors and those in the shoe repair industry often recommend inserts to increase shoe comfort. 【小题3】.

3. 【小题4】

The way you lace (由带子系紧) your shoes can make a world of difference in their comfort. Lacing them too tightly or incorrectly can make your feet hurt. Cramped toes, rubbing on the top of the foot, and pressure on the big toe can likely be relieved if you lace your shoes different.

4. Wearing Socks

【小题5】.They are usually made of cotton or nylon. Not only do they add an extra layer of cushion to your shoes but they also keep your feet from sweating. This prevents moisture (水汽) from forming in the shoe. Moisture in your shoes can cause blisters and calluses on your feet.

What to Do when Someone Doesn’t Like You

When someone tells me, “I don’t care if people like me,” they are showing me the emotional wall they use to block the hurt of rejection.

As humans are social animals, all of us care if people like us. Based on the need for social connections, your reactions to rejection and negative judgment can range from minor hurt to breakouts of depression. 【小题1】

The first step to handle a negative situation is to recognize your reaction. Ask yourself, “What am I feeling?”. 【小题2】 Any betrayal (背叛) or embarrassment in your heart? Identify what feeling has shown up in your body, so you can choose what to do next.

【小题3】 When you sense yourself being shut out or feel defensive, ask yourself what the person actually means to do to you. Does he truly mean to offend you, or make fun of you? Your brain works very hard to keep you safe, so it will judge a situation threatening if there is any possibility of social harm.

When our brains sense a possible threat, we react as if we were personally attacked. Take a breath to relieve (减轻) the stress. 【小题4】

Finally, if you believe the person doesn’t like you, ask yourself if this matters. 【小题5】 If not, what can you do to release your need to be liked by this person? And, what can you do to stay neutral and not return the dislike? The more you can come to accept others as who they are, the more you can move forward with your goals regardless of whether someone likes you or not.
