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 

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.

    Many years ago，when I was fresh out of school and working in Denver，I was driving to my parents' home in Missouri for Christmas. I stopped at a gas station about 50 miles from Oklahoma City，where I was planning to stop and visit a friend. While I was standing in line at the cash register(收款台)，I said hello to an older couple who were also paying for gas.

    I took off ， but had gone only a few miles when black smoke poured from the back of my car. I stopped and wondered what I should do. A car pulled up behind me. It was the couple I had spoken to at the gas station. They said they would take me to my friend's. We chatted on the way into the city，and when I got out of the car，the husband gave me his business card.

    I wrote him and his wife a thank­you note for helping me. Soon afterward，I received a Christmas present from them. Their note that came with it said that helping me had made their holidays meaningful.

    Years later，I drove to a meeting in a nearby town in the morning. In late afternoon，I returned to my car and found that I'd left the lights on all day，and the battery(电池) was dead. Then I noticed that the Friendly Ford dealership—a shop selling cars—was right next door. I walked over and found two salesmen in the showroom. “Just how friendly is Friendly Ford？” I asked and explained my trouble. They quickly drove a pickup truck to my car and started it. They would accept no payment，so when I got home，I wrote them a note to say thanks. I received a letter back from one of the salesmen. No one had ever taken the time to write him and say thank you，and it meant a lot，he said.

    “Thank you”—two powerful words. They're easy to say and mean so much.

    It's always important to use the right tools for any job. Success in school is no different. If you need to vary your time management tool box, consider these less traditional tools. {#blank#}1{#/blank#} .

    Daily Task List

    A daily task list is nothing more than a notepad that you use to list your daily goals. {#blank#}2{#/blank#} . Cross them off as you finish them. At the end of each day, simply carry over any job that you didn't finish to the next day's list. It works wonders!

    Big Well Calendar

    Simply place the big wall calendar in a prominent place near your regular study space. Then come up with a color code for your classes(like green for math and yellow for history). When you have a big due date or a test date, place the appropriate colored sticker on that date. {#blank#}3{#/blank#} , so it works as a constant reminder. This trick is simple, cheap, and so effective!

    Sticky Note Flags

    {#blank#}4{#/blank#} , whether you're putting together a big research project or you're simply reading a book. Whenever you need to remember to take a certain object or assignment to school, place a sticky flag on the door knob, bathroom mirror, or the cereal box the night before. It works like an alarm!

    Bedside Notepad

    You can keep a notepad beside your bed to write down any items or tasks you have to remember for the next day. As you settle in for the night, take a few moments to think about the things you need to do tomorrow. Then write them down and tear off the sheet in the morning. {#blank#}5{#/blank#} !

A. Remember to pack it in your schoolbag.

B. Keep your homework and your life in order

C. Two heads are better than one when it comes to projecting due dates

D. You could also use the calendar feature to alert you when projects are due

E. These little paper banners are lifesavers when it comes to getting organized

F. Carry a small pad around and write down every task you need to complete

G. The sticker will be something you can see every time you enter the room.

    If you're encouraged by the tiny house movement and think 160 square feet is just enough for your needs, you may want to contact the Academy of Construction and Design (ACAD) at IDEA Public Charter School in northeast Washington．

    Students in the program built a micro house with a kitchen, a bathroom, a sleeping loft with space for a queen-size bed and a storage loft, all set on a trailer for mobility. The exterior (外部) of the house was part of a continuous living exhibit in 2015and was moved to the IDEA campus so students could work with builders to complete the interior earlier this year.

    McMahon said the D.C. government's approval to push companies to hire District residents (居民) was at odds with the school system not preparing students for careers in construction, exploring or electrical work. McMahon gathered industry and community leaders to establish ACAD in 2005 and he said 100 percent of the companies he contacted responded positively to the idea, including major firms such as JBG, Clark Construction, Hines Construction and Boston Properties.

    “When students make the connection between what they are learning a potential career, their academics improve dramatically,” said Carol Randolph, chief operating officer of the D.C. Students Construction Trades Foundation. “Some of them who didn't think college was an choice now have a better chance because their classes have become relevant to a job.”

    “We teach them life skills and explain that even if you start as a laborer, there are opportunities to move up quickly,” he said. “We rewrite the story for them and explain that they can work for a few years, make good money, get promoted, and start their own business or go to school with less debts.”

    “Parents and school advisors can be the biggest obstacles because of the negative idea of construction as a blue-collar career,” Karriem said. “I get middle-school advisors on board to talk about the opportunities this education provides. These kids are learning lifelong skills that can help them in other fields, provide them with income and allow them to take care of their homes.”

    I'll never forget the day when Mary came into my office and said, I am too old to learn how to use a computer. I shook my head. Here was a woman who had raised 6 children and who had made great progress in her career telling me that she was too old to learn something new. I told her that I always believed people were never too old to learn.

    Mary followed my advice and did learn how to use the computer. Now, she is retired and leading a very active life volunteering in her community( 社区 ),using her computer skills and helping anyone that needs help.

    When she was in her sixties, one day she called me and said she had played the piano for others all her life, and now she was going to make a CD of her own. My mind flashed back to the day when she told me she was too old to learn. You can imagine my surprise and delight.

    To produce the CD, she had a lot of things to learn. It was not just sitting at the piano and playing. She had to research the songs, learn about copyright(版权),and learn about marketing. It was pretty amazing for someone who once said she was too old to learn. And finally she made it. Now she has her own CD-Mixed Blessings.

    Most of you probably have heard about some people who have gone back to university in their seventies and have also graduated. They are on their way again to charging themselves with a new skill and a new attitude towards life. The point is you are unable to learn anything at any age if you believe you are too old. On the contrary, you can achieve anything at any age if you believe you can.

    Introduction

    Blenheim Palace is one of the Europe's largest and greatest palaces. It was built between 1705 and 1722 as a reward of the British government to John Churchill, 1st Duke of Marlborough, for defeating King Louis XlV's army at Blenheim, a small Bavarian village on the Danube River. The palace was designed by Sir John Vanbrugh, which displayed strength and arm glory. It is the largest non-royal building in England and is now listed by the UNESCO as a World Heritage Site.

    Winston Churchill

    In 1874, the palace was the birthplace of the duke's most famous descendant. Winston Churchill, who was to become the UK's Prime Minister (some would say Britain's greatest 20th-century politician) and Nobel prize winner for literature. It is also in Blenheim that Winston got married to Clementine Hozier in 1908.

    A lasting exhibition is devoted to the man's life, work and writings. Winston and his wife are buried in Bladon Church within the palace.

    Opening Hours & Admission

    Blenheim is still the home of the 11th Duke of Marlborough and is therefore not open all year round (although the park is). The palace opens its doors to visitors from 12 February to 11 December. Entry to the palace, park and gardens cost £11.50 during the low season and £13 during the peak season (Easter weekend and from 28 May toll September), or £6/£8 for the park and gardens only.

    The park is open all-year round from 9am to 4:45pm (last entry). Admission is £2.50 for adults and £1.50 for children.
