              It was my dream to become a pop singer when I was a teenager. But I might have never made my dream come true if I hadn’t been encouraged by one of my art teachers.

               As a twenty-year-old boy, I was greatly discouraged and resolved to give up my dream. What I always got from people around me was that I’d never become a famous pop singer. Besides, I wasn’t good-looking.

               I wrote an e-mail to my teacher and told him that I wanted to give up singing. My teacher e-mailed me back and we made an appointment to meet on the weekend. We met each other at a cafe near our college and ordered two cups of coffee and some dessert. He talked with me in a relaxing way for a while and then asked me if I had made up my mind. I nodded.

               He opened the suitcase that he brought and took out a few paintings, asking me what I thought about them. Though confused, I looked at them carefully, feeling that they were worthless. “They are not good,” I said. He then took out some other paintings to me. I looked over the second group

              of paintings and became surprised at the talent they showed. “These are really good. Who painted them?” I asked.

               “They were all painted by me. But I painted the good ones in my forties. Before that nobody would say I had a gift for painting, but I never cared, for it was my dream to paint. If I had given up at your age, you would never see the good ones,” he said.

               I felt ashamed at what I had though and decided to keep following my dream no matter what happened. I released my first album just a few years later. Now I’m always busy singing all over the country and always say to the young, “Never give up.”

              Learn from mistakes

                    The best way to learn something is to make mistakes first. Thomas Edison, who invented the light bulb, told his colleagues: “Of the 200 light bulbs that didn’t work, every failure told me something I was able to incorporate into the next attempt.” Benjamin Franklin, the US statesman and scientist once said: “I haven’t failed. I have had 10,000 ideas that didn’t work.”

                    Both these people understood that failures and false starts are the condition of success. In fact, a surprising number of everyday objects had their beginnings in a mistake or a misunderstanding. Post-it notes, packets of crisps and even bread are all unexpected inventions. In 2600 BC, a tired Egyptian slave invented bread when the dough rose during his sleep. And crisps were first cooked by a chef in the USA when a customer complained that his fried potatoes were not thin enough.

                    In 1968 Spencer Silver was trying to develop a strong adhesive when he accidentally invented a very weak glue instead. His colleague, Art Fry, decided to use it six years later, in 1974, to hold his bookmarks in his books and the post-it note was invented.

                    Successful businesspeople have often made big, expensive mistakes in their past. When an employee of IBM made a mistake that cost the company $600,000, Thomos Watson, the chairman, was asked if he would fire the man. “Of course not,” he replied. “I have just spent $600,000 training him. I am not going to let another company benefit from experience.”

                    The important thing to remember is that you need to learn from your mistakes. If you don’t, then there is no sense in making them.

              Almost everybody in America will spend a part of his or her life behind a shopping cart(购物手推车). They will, in a lifetime, push the chrome-plated contraptions many miles. But few will know—or even think to ask—who it was that invented them.

              Sylvan N. Goldman invented the shopping cart in 1937. At that time he was in the supermarket business. Every day he would see shoppers lugging(吃力地携带) groceries around in baskets they had to carry.

              One day Goldman suddenly had the idea of putting baskets on wheels. The wheeled baskets would make shopping much easier for his customers, and would help to attract more business.

              On June 4, 1937, Goldman’s first carts were ready for use in his market. He was terriblyexcited on the morning of that day as customers began arriving. He couldn’t wait to see them using his invention.

              But Goldman was disappointed. Most shoppers gave the carts a long look, but hardly anybody would give them a try.

              After a while, Goldman decided to ask customers why they weren’t using his carts. “Don’t you think this arm is strong enough to carry a shopping basket?” one shopper replied.

              But Goldman wasn’t beaten yet. He knew his carts would be a great success if only he could persuade people to give them a try. To this end, Goldman hired a group of people to push carts around his market and pretend they were shopping! Seeing this, the real customers gradually began copying the phony(假冒的) customers.

              As Goldman had hoped, the carts were soon attracting larger and larger numbers of customers to his market. But not only did more people come—those who came bought more. With larger, easier-to-handle baskets, customers unconsciously bought a greater number of items than before.

              Today’s shopping carts are five times larger than Goldman’s original model. Perhaps that’s one reasonAmericans today spend more than five times as much money on food each year as they did before 1937—before the coming of the shopping cart.

              (1) The underlined words “chrome-plate contraptions” in Paragraph 1 refer to ______.(No more than 3 words) (2) What was the purpose of Goldman’s invention?(No more than    10 words) (3) Why was Goldman disappointed at first?(No more than 10 words) (4) Why did Goldman hire people to push carts around his market?(No more than 10 words) (5) What do you think of Goldman?

              When Steve Jobs was born on February 24,1955, in San Francisco, California, his unmarried mother decided to put him for adoption because she wanted a girl. So in the middle of the night, his mother called a lawyer named Paul Jobs and said, "We have an unexpected baby boy, do you want him?" But his mother told his future parents to promise that they would send Jobs to college. After Steve Jobs graduated from high school, he went to college but decided to dropout because it was so expensive that he had to sleep on the floor in his friends' rooms.

But after he had to leave the company, Apple was under heavy pressure from rival Microsoft and in 1996 posted billions of dollars in losses. Apple needed Steve Jobs and he was appointed as Apple's CEO in 1997.Under his leadership, Apple returned to profitability introducing new products such as the iPod, the iPhone and the iPad.

                 Steve Jobs once said, "Sometimes life hits you in the head with a brick, don't lose faith. I'm convinced that the only thing that kept me going was that I loved what I did. You've got to find what you love. If you haven't found it yet, keep looking."

              Zebras have their own bug repellent(驱虫剂)?

              Eww bugs! They are so annoying! We humans are lucky that we can apply repellents to avoid nasty bites. But what’s an animal to do? They have no choice but to spend their days shooing them off with their tails, unless, of course, they are zebras, who apparently have their own automatic repellent--- their striped skin!

              Scientists had originally thought that the reason why the animal had developed the black and white lines was to help protect itself from predators (食肉动物)in the African savannah(大草原), because the stripes make it difficult to single out one zebra that is traveling with a herd. While that may be true, the theory has never been tested or proven. Now the experts have another---that the stripes have evolved to repel the annoying horse flies that not only feed off their blood, but also, transmit dangerous germs into the bodies of these innocent animals.

              The study was performed by a team of Swedish scientists. One of the clues that got them thinking along these lines was the fact that darker horses got bitten more often than light-colored or white ones.

              The fact that zebras are born black and only develop stripes as they grow older made the scientists theorize that the stripes may be something the animals have developed to make themselves less attractive to flies.

              To test if this may be the case, they painted some boards at a horse-infested(寄生的) horse farm in Budapest with patterns of black and white stripes of varying widths and applied a layer of glue on them. What they noticed was that the places where the black and white stripes were at their narrowest (similar to what zebras have) attracted the fewest flies. They achieved similar results when they painted horses with black and white zebra-like stripes.

              While the research are not sure why this may be the case, they believe it may be something to do with the way insects operate---horseflies are attracted to horizontally polarized light(偏振光); since white does not reflect it, white horses are luckier than black ones. But zebras seem to be the luckiest of all. When the researchers measured the polarized light reflected from real zebra skins, they found that it matched light patterns that were the least attractive to horseflies.

              While this theory does make logical sense, nobody is 100 percent sure that it is really true, given that it has never been tested on a real zebra. If it is true, it does raise the question of why a horse, a close relative of the zebra has failed to develop stripes. The researchers believe that this could be because there are more horseflies in Africa, where zebras reside, then anywhere else in the world.
