My Choice

Directions: Choose a book from the list below and bring it to class by the due date. You will have about one term, from September 14 to November 16, to read the book and finish your report. It is okay to change your book if you do not like your original choice. Students are encouraged to check out the book of their choice from the public library.

It's optional to buy a book.

    Researchers at Stanford University have developed a new material that can move heat out of buildings and into space. The researchers say the material can cool buildings even on hot days. The cooling material is a very thin sheet with many layers that could be placed on a roof like solar panels(板). However, instead of turning sunlight into energy as solar panels do, the material turns heat into infrared（红外线的）radiation.

    Shanhui Fan is an electrical engineering professor at Stanford University. He says that the panels have a layer of material that is like sand. The panels act like a mirror. They take heat out of buildings and reflect the light from the sun. And he says both the heat and sunlight arc sent 100 kilometers into outer space. "It's a structure that cools itself without electricity input, even under the sun. So, what it does is basically radiate heat to outer space and also reflect the sunlight so it doesn't get heated up by the sun. Mr. Fan says it is like having a window into space. The heat is sent directly into space without increasing the air temperature

    He says buildings in developing countries that do not have electricity or air conditioning could use the panels. "In areas where electricity is out of reach for many people, there is a potential benefit for storing medicine or even food. In many of these situations, being able to reduce the temperature is important. And this would provide a way to do it.”

    The researchers say the main problem is creating actual cooling systems using the high-tech panels. They say it may be possible to develop a cooling spray(喷涂）that could be used on present solid structures. They believe the cooling spray technology could be developed in the next three to five years. They say as much as 15 percent of the energy used in the United States is spent providing power to air conditioning systems.

Blake Mycoskie set up five businesses, but later he sold them all at a profit. Feeling a bit burned out from work, Mycoskie decided to give it a break for a while and headed down to Argentina for some rest. But rest isn't really part of a businessman's make-up. It's in their nature to keep having good business ideas.

On a visit to a village outside Buenos Aires, he was shocked to see that many children didn't have any shoes or, if they did, the shoes were badly worn. Since shoes—particularly the local farmers' canvas(帆布的)shoes—can be bought cheaply in Argentina, Mycoskie's first instinct(本能) was to set up a charity to donate shoes to the children. But after giving it some thought, he realized that this was not a model that would work. One pair of shoes per child would not make that much difference, because they wear out(磨损). And if he asked people to donate repeatedly —to provide new shoes for the same child every six months—the donors' sympathy(同情)for the cause might also wear out pretty quickly.

Instead he came up with the idea of "TOMS:  one-for-one shoes". He would take the canvas shoe to America, manufacture it and sell it as a high end fashion item at around $ 50 a pair. For each pair he sold he would donate one pair to shoeless village children. That way he could guarantee a continual supply.

Several years on, the business is very successful, supplying shoes not only to children in Argentina but also other parts of the world. But can the one-for-one model be repeated with other products? Mycoskie is doubtful. TOMS is a for-profit business, but does not yet make a profit. He says one-for-one is not an offer that you can just add to your existing business model; you have to build it from the beginning.

Some would also argue that the charity aspect is just a marketing tool, but in the end does that matter? TOMS is making a real difference to poor children all over the world and Mycoskie is enjoying being a businessman more than ever.

A call came into Gilleece's bar. A newly married woman, who had spent the afternoon at the beach bar, couldn't find her wallet. She didn't1about her ID or credit cards, but her2was inside it.

Gilleece, 42, didn't like 3 occurred at his place, so he set out to4the wallet. He spent hours 5 surveillance cameras (监控摄像机), seeing the woman staying in the bar until she went to sit on a bench outside. Within minutes, a young man6the bench after the woman left, put something in his pocket, and walked off. Gilleece7a clip (片段) on the bar's Facebook page to find the boy.

Within hours, Gilleece got a text from 17­year­old Rivers Prather. Prather8having taken the wallet and told Gilleece he'd done it because he hadn't 9 for two days. He said he saw the ring but thought it was a(n) 10 one, so he took the money and 11 the wallet. Then he bought a sandwich.

Gilleece wasn't sure if he could 12 the boy, so he told the teen to meet him at the bar. There, they got to talking, and Gilleece, a father of two, saw Prather was more of a kid than a(n) 13.

"He would be going to big boy jail (监狱)，" Gilleece says. "I had to 14 him somehow." Gilleece hired two local divers to __15__ the waters. More than one hour passed, with no __16__ of the ring. Gilleece grew17, especially when the detective tried to get the boy to jail. A diver popped up 18. In his hand was the wallet, and inside was the ring.

"Most people would have given the video to the 19, but he chose to help me and offered me a job," Prather told CBS News. "I'm20of all the support he has given me."

他有许多麻烦，但是他说没有什么不能被解决。
