Modern festival-goers who worry about ending up with a dead mobile phone battery(电池) after days stuck in a muddy field with no electric plug power points may now have a solution——power boots(靴子).

Mobile phone company European Telco Orange has introduced a phone charging(充电) prototype—— a set of thermoelectric gumboots or Wellington boots with a “power generation sole” that changes heat from the wearer’s feet into electrical power to charge battery-powered hand-helds.

The boot was designed by Dave Pain, managing director at GotWind, a renewable energy company. Pain said the boot uses the Seebeck effect, in which a circuit made of two dissimilar metals conducts electricity if the two places where they connect are held at different temperatures. “In the sole of the Wellington boot there’s a thermocouple and if you apply heat to one side of the thermocouple and cold to the other side it produces an electrical charge,” Pain said. “That electrical charge we then pass through to a battery which you’ll find in the heel of the boot for storage of the electrical power for later use to charge your mobile phone.” These thermocouples are connected electrically, forming an array of multiple thermocouples (thermopile). They are then sandwiched between two thin ceramic wafers. When the heat from the foot is applied on the top side of the ceramic wafer and cold is applied on the opposite side, from the cold of the ground, electricity is made.

But the prototype boot does have one drawback. You have to walk for 12 hours in the boots to make one hour’s worth of charge.

A. who like traveling in the wild

“Keep your eyes on the ball.” That is good advice when you are on the playing field, and good advice for everyday life. “Keep your mind on what’s important,” is the way I’d put it. But people are funny. They think too much about the details.

I had a secretary once. She was very hardworking. I ran a school and people used to call up to enroll(登记) for courses. Berry used to get angry at the phone. “If they keep on ringing, I’ll never get my typing done!” she’d shout.

People just don’t see the big picture. One evening, after leaving work, I was sitting next to a man on the train. I was feeling tired. My eyes fell on the paper he had spread out in front of him. You know how you feel to read over someone’s shoulder?

I read the page and leaned back. I guessed I was waiting for him to turn it. After a while, I realized—he wasn’t turning the page. He just kept on reading.

Now if you knew the page he was reading, you’d know that there weren’t many words on the page to read anyway. The layout(版面) was mostly pictures. So I turned to the man and said,” You know, you really read very slowly.”

“What do you mean?” he asked. “Well,” I told him, “I read the page in about a minute, and you have taken about ten. And you are still reading. You know,” I went on “If you learned to read faster, you could get more reading done.” He remained silent for a minute or two. “If I read too fast, my paper wouldn’t last me to my station.”

1.The writer wasn’t satisfied with his secretary because ___.

A. she didn’t put first thing first

B. she was too busy

C. she was easy to get angry

D. she couldn’t finish her work on time

2.The man read newspaper in order to___.

A.  take in information   B.  enjoy pictures

C.  save time            D.  kill time

3.The writer thinks that people seem to need a sense of ___.

A. what to read first   B. how to read fast

C. what is important   D. what is funny

It was almost five years since I began to learn English. I’m glad to say I’m getting along well with it. However, first I came across a lot of difficulties. I couldn’t pronounce English sounds good, nor could I remember the words I had learned. In class, I couldn’t understand that the teacher had said. I almost lost my heart when the teacher said to me, “Keeping on and you will do well.” I was greatly encouraging. I started working hard at English. With the help by my teacher and classmates, I made some progresses. I’m very pleased, but I will work harder.
