Jeremy Shu-How Lin, who was born in California, 1988, world-famous now，is the first Chinese-American professional basketball player with the New York Knicks of NBA.
It hasn't been an easy road for Lin. After high school, Lin sent his resume(简历) and a DVD of highlights to all the Ivy League schools, and his dream schools Stanford and UCLA. Harvard and Brown were the only schools that guaranteed him a spot on their basketball teams, but Ivy League schools do not offer athletic scholarships.
After graduating from Harvard University, Lin went undrafted in the 2010 NBA Draft . Lin spent his first season with his hometown the Golden State Warriors. He saw limited minutes with the Warriors, but was cheered in arenas(比赛场) around the country, particularly in cities with large Asian communities, as fans came out in crowds to cheer their homegrown star. In late 2011, Lin spent less than two weeks with the Houston Rockets, moving to the New York Knicks at the very end of the year.
He has made several trips to the NBA's Development League, a minor league for players who show promise but need seasoning before they can compete at the highest level. It appears to have paid off. In February 2012, after keying the Knicks victory over New Jersey, Lin was named the starter for the Utah game, a position he appears to have a hold on in the short term, as Baron Davis, who signed in December to play the position, stays on the disabled list. Lin will likely get stronger the more minutes he plays, and even if Davis returns, spelling the older, recovering player could be productive for Lin: a proven good student who can learn a lot from practicing against a veteran.
Without the services of All-Stars Carmelo and Amare, Lin led New York to a 4-0 record last week. He became the first player in NBA history to record at least 20 points and seven assists in each of his first four starts, which generated a global following known as Linsanity. The Associated Press called Lin "the most Surprising story in the NBA".

Some years ago industries had more freedom than they have now, and they did not need to be as careful as they must today. They did not need to worry a lot about the safety of the new products that they developed. They did not have to pay much attention to the health and safety of the people who worked for them. Often new products were dangerous for the people who used them; often conditions in the work place had very bad effects on the health of the workers.
Of course sometimes there were real disasters which attracted the attention of governments and which showed the need for changes. Also scientists who were doing research into the health of workers sometimes produced information which governments could not ignore. At such times, they inquire into the causes of the disasters or the problems. New safety rules were often introduced as a result of these inquiries; however. the new rules came too late to protect the people who died or who became seriously ill.
Today many governments have special departments which protect customers and workers．In the U.S, for example, there is a department which tests new airplanes and gives warnings about possible problems. It also makes the rules that aircraft producers must follow. Another department controls the foods and drugs that companies sell. A third department looks at the places where people work. and then reports any companies that are breaking the laws which protect the health and safety of workers. Of course, new government departments and new laws cannot prevent every accident or illness. but they are having some good results. Our work places are safer and cleaner than before. The planes and cars which we use for travel are better. Producers are thinking more about the safety and health of the people who buy and use their products.

Gauri Nanda sees a wearable computer as a handbag — one that’s built out of four-inch squares and triangles of fiber, with tiny computer chips embedded (嵌入) in it. It looks, feels and weighs like your typical leather purse.
That’s where similarities end: This bag can wirelessly keep track of your belongings and remind you, just as you’re about to leave the house, to take your wallet. It can review the weather report and suggest that you grab an umbrella. This purse can even upload your favorite songs onto your scarf.
Sure, a computing purse and scarf set may seem like the stuff of science fiction. But these devices, part of next generation of wearable computers, could become commonplace within a few years. DuPont created new super strong fibers that can conduct electricity and can be woven into ordinary-looking clothes. And the chipmaker developed chip packaging allowing wearable computers to be washed, even in the heavy-duty cycle.
As a result, these new wearable devices are different from the heavy and downright silly versions of the recent past, which often required users to be wrapped in wires and type on their stomachs. Unlike their predecessors, these new wearable computers also make economic sense. When her bag becomes commercially available in two to three years, Nanda expects it will cost around $150, which is the price of an average leather purse.
Here’s how the bag works: You place a special radio-signal-transmitting chip on to your wallet. A similar radio in your purse picks up the signal and notifies you that you’ve forgotten to take your wallet. In turn, sensors on your purse’s handles will notify the computer that you’ve picked up the purse and are ready to go.
Already, these new kinds of wearable devices are being adopted for use in markets like auto repair, emergency services, medical monitoring — and even, increasingly, for consumers at large. Indeed, more people will want to cross that bridge in the coming years — making for a booming market for wearable computers that don’t like something out of science fiction.

I had an experience some years ago, which taught me something about the ways in which people make a bad situation worse by blaming themselves．One January, I had to hold two funerals on successive days for two elderly women in my community．Both had died “full of years”, as the Bible would say．Their homes happened to be near each other, so I paid condolence （吊唁） calls on the two families on the same afternoon.
At the first home, the son of the deceased （已故的） woman said to me, “If only I had sent my mother to Florida and gotten her out of this cold and snow, she would be alive today．It’s my fault that she died.” At the second home, the son of the other deceased woman said, “If only I hadn’t insisted on my mother’s going to Florida, she would be alive today．That long airplane ride, the sudden change of climate, was more than she could take．It’s my fault that she’s dead.”
You see that any time there is a death, the survivors will feel guilty．Because the course of action they took turned out badly, they believe that the opposite course — keeping Mother at home, putting off the operation — would have turned out better．After all, how could it have turned out any worse?
There seem to be two elements involved in our willingness to feel guilty．The first is our pressing need to believe that the world makes sense, that there is a cause for every effect and a reason for everything that happens．That leads us to find patterns and connections both where they really exist and where they exist only in our minds.
The second element is the view that we are the cause of what happens, especially the bad things that happen．It seems to be a short step from believing that every event has a cause to believing that every disaster is our fault．The roots of this feeling may lie in our childhood.
A baby comes to think that the world exists to meet his needs, and that he makes everything happen in it．He wakes up in the morning and summons the rest of the world to its tasks．He cries, and someone comes to attend to him．When he is hungry, people feed him, and when he is wet, people change him．Very often, we do not completely outgrow that childish view that our wishes cause things to happen.

For most people, shopping is still a matter of wandering down the street or loading a cart in a shopping mall．Soon, that will change．Electronic commerce （trade） is growing fast and will soon bring people more choices．There will, however, be a cost: protecting the consumer from being cheated will be harder．Many governments therefore want to apply street regulations to the electronic world．But politicians would be wiser to see cyberspace as a basis for a new era of corporate self-regulation．
Consumers in rich countries have grown used to the idea that the government takes responsibility for everything for the stability of the banks to the safety of the drugs or their rights to refund when goods are faulty．But governments cannot enforce national laws on businesses whose only presence is on the screen．Even in a country where a clear right to compensation exists, the on-line customer in Tokyo, say, can hardly go to New York to get a refund for a clothes purchase．
One answer is for government to cooperate more: to recognize each other’s rules．But that requires years of work and volumes of detailed rules．And plenty of countries have rules too fanciful for sober countries to accept．There is, however, another choice．Let the electronic businesses do the regulation themselves．They do, after all, have a self-interest in doing so．
In electronic commerce, a reputation for honest dealing will be a valuable competitive asset．Governments, too, may compete to be trusted．For instance, customers ordering medicines on-line may prefer to buy from the United States because they trust the rigorous screening of the Food and Drug Administration; or they may decide that the FDA’s rules are too strict, and buy from Switzerland instead．
Customers will still need to use their judgment．But precisely because the technology is new, electronic shoppers are likely for a while to be a lot more cautious than customers of the normal sort．And the new technology will also make it easier for them to complain when a company lets them down．In this way, at least, the advent of cyberspace may argue for fewer consumer protection laws, not more．
According to the author, what will be the best policy for electronic commerce?

A．Self-regulation by the business．	B．Strict consumer protection laws．
C．Close international cooperation．	D．Government protection．

In case an electronic shopper bought faulty goods from a foreign country, what could he do?

A．Refuse to pay for the purchase．	B．Go to the seller and ask for a refund．
C．Appeal to consumer protection law．	D．Complain about it on the Internet．

In the author’s view, businesses would place a high emphasis on honest dealing because in the electronic world _________________________________．

A．international cooperation would be much more frequent

B．consumers could easily seek government protection

C．a good reputation is a great advantage in competition

D．it would be easy for consumers to complain
