I was blind, but I was ashamed of it if it was known. I refused to use a white stick and hated asking for help. After all, I was a teenage girl, and I couldn't bear people to look at me and think I was not like them. I must have been a terrible danger on the roads. Coming across me wandering through the traffic, motorists probably would have to stop rapidly on their brakes. Apart from that, there were all sorts of disasters that used to occur on the way to and from work.

One evening, I got off the bus about halfway home where I had to change buses, and as usual I ran into something. "I'm awfully sorry," I said and stepped forward only to run into it again. When it happened a third time, I realized I had been apologizing to a lamppost. This was just one of the stupid things that constantly happened to me. So I carried on and found the bus stop, which was a request stop, where the bus wouldn't stop unless passengers wanted to get on or off. No one else was there and I had to guess if the bus had arrived.

    Generally in this situation, because I hated showing I was blind by asking for help, I tried to guess at the sound. Sometimes I would stop a big lorry and stand there feeling stupid as it drew away. In the end, I usually managed to swallow my pride and ask someone at the stop for help.

    But at this particular evening no one joined me at the stop; it seemed that everyone had suddenly decided not to travel by bus. Of course I heard plenty of buses pass, or I thought I did. But because I had given up stopping them for fear of making a fool of myself, I let them all go by. I stood there alone for half an hour without stopping one. Then I gave up. I decided to walk on to the next stop.

    Astronomy (天文学) is the oldest science known to man. Thousands of years ago man looked at the stars and wondered about heavens(天堂). But the six planets that he could see with his eyes alone limited man.

    The Greeks studied astronomy over 2,000 years ago. They could see the size, color, and brightness of a star. They could see its place in the sky. They watched the stars move as the seasons changed. But the Greeks had no tools to help themselves study the heavens.

    Each new tool added to the field of astronomy helped man reach out into space. Until there were telescopes(望远镜), man did not know much about the moon. He did not know that the planet called Saturn(土星) had rings around it. His sight was so limited that he could not see all the planets. In the early 1700s, people thought there were only six planets. Pluto (冥王星), the last of the nine planets to be discovered was seen until 1930.

    Before the spectroscopes (分光镜), man didn't know what kind of gas was in the sun or other stars, without radio telescopes(射电望远镜), we did not know that radio noise came from far in space.

    Today, astronomy is a growing science. We have learned more in the past fifty years than in the whole history of astronomy.

    The "Give It Up for Earth Day" encourages people to commit to giving up actions that are harmful to the environment, such as using poisonous cleaners.

    Throughout the month of April, Canadians are being asked to "Give It Up for Earth Day!" Earth Day has been celebrated every year on April 22 since 1970. Earth Day Canada president Jed Goldberg says that as people become more environmentally aware, they want to find ways to reduce their environmental influence, not just celebrate one special event.

    "Earth Day is a great launching pad for thinking about environmental action every day," said Goldberg. "Choosing healthier options, even for the short term, can lead to thinking about the influence of our decisions for a lifetime."

    That's the reason behind the "Give It Up for Earth Day" campaign. It's designed to encourage healthy habits that benefit people and the planet. It challenges everyone to help create a healthier world by making changes in their daily routine.

    "We wanted to plan an action—targeted campaign that will give people a chance to act on their concern for the environment in a positive way," said Goldberg.

    The campaign has identified four daily actions that can add up to huge environmental savings. They include pledging (保证) to turn off the TV, give up the use of poisonous cleaners, reduce consumption of consumer products and cut out meat.

    At the end of April, all of the pledges will be recorded and converted (转化) into the number of TV hours not watched, dollars not spent on unnecessary items, electricity saved, greenhouse gas emissions (排放) avoided by cutting out meat, and poisonous chemicals produced from homes and landfills.

    "What we're trying to achieve this year for Earth Day is to give people a chance to do something that is meaningful and measurable," said Goldberg.

    An 80-year-old man was sitting on the sofa in his house along with his 45-year-old highly educated son.

    Suddenly a crow (乌鸦) perched on the tree near their window.

    The father asked his son, "What is this?"

    The son replied, "It is a crow."

    After a few minutes, the father asked his son the second time, "What is this?"

    The son said, "Father, I have just now told you. It is a crow!"

    After a little while, the old father again asked his son the third time, "What is this?"

    "It's a crow, a crow, a crow!" said the son loudly.

    A little after, the father again asked his son the fourth time, "What is this?" This time the son shouted at his father, "Why do you keep asking me the same question again and again? 'IT IS A CROW'. Are you not able to understand this?"

    A little later the father went to his room and came back with an old diary, which he had kept since his son was born. On opening a page, he asked his son to read that page. When the son read it, the following words were written in the diary:

    "Today my little son aged three was sitting with me on the sofa, when a crow was sitting on the window. My son asked me 23 times what it was, and I replied to him all 23 times that it was crow. I hugged him lovingly each time he asked me the same question again and again for 23 times. I did not at all feel annoyed; I rather felt affection for my innocent child."

    In China, chain restaurants especially the big multinational ones are cool. Going to Starbucks, for example, is a status symbol. It not only says, "I'm rich enough to buy this overpriced coffee, "but also, "I'm cosmopolitan (见多识广的) enough to be part of globalization."

    Where I come from in the UK, however, chains are neither fashionable nor gourmet (美食的). Chains are where you go on New Year's Day when nowhere else is open, or when you are 5 years old and your parents can't stand hearing, "I'm hungry!" any longer. In my own case (with regards to McDonald's), a chain is where you are taken on your first "date". Even at the age of 13, I knew to give the guy the "let's just be friends" phone call the next day.

    In the UK, independent cafes and restaurants are making a comeback on the fashion scene. Nowadays, a Londoner who says "let's meet for a coffee at Monmouth" (an independent café) is much cooler than one who says "let's go to Starbucks". Even if Monmouth's coffee is a little more expensive, there's a satisfaction in knowing your pounds aren't going straight to the big corporations.

    Of course, there are chain stores all over the UK; you can't go five minutes without spotting a Costa Coffee. But numbers do not add up to good taste.

    I do, however, have a confession (坦白). After moving to China I had moments when all the rice and Kung Pao Chicken became too much. I, too, have retreated to McDonald's.
