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.

    Renowned British physicist Stephen Hawking died peacefully at his home in the British university city of Cambridge in March 14 at age 76.

    Hawking, whose 1988 book "A Brief History of Time" became an unlikely worldwide bestseller and cemented (奠定) his superstar status, dedicated his life to unlocking the secrets of the Universe. He held the post of Lucasian Professor of Mathematics at the University of Cambridge, which is a position that was once held by Sir Isaac Newton.

    Born in 1942 in Oxford, where his parents spent the final months of pregnancy to avoid the bombings of London, Hawking was said to have been a good student although it wasn't until he was in his 20s that his true potential began to really shine through. Having initially wanted to study Mathematics, Stephen Hawking chose, instead, to read natural sciences with emphasis on Physics.

    Having found University life boring, so much so that he joined the University rowing team to relieve the boredom, it was only following an oral examination that he was awarded a first class degree.

    While at Cambridge, Hawking was diagnosed with a motor neurone (神经元）disease. He was initially given two to three years to live. The illness gradually robbed him of mobility, leaving him confined to a wheelchair, almost completely paralysed and unable to speak except through his trademark voice synthesiser (合成器）.

    Stephen Hawking led an incredible and well documented life. He was referred to in many TV programs, films, and even songs, and appeared as himself in a number of programs including Red Dwarf and the Big Bang Theory. His genius and wit won over fans from far beyond the world of astrophysics (天体物理学）, earning comparisons with Albert Einstein and Sir Isaac Newton.

    Charlie studied in a famous college for four years. He studied hard and did well in all his subjects. He hoped to become a good teacher. This year he left the college and began to work in a middle school. He likes his students and is strict with them. He does his best to make his classes lively and interesting.

    One day he carefully explained a chemical reaction to the students of Grade 2 in the chemistry lab.

    “Be careful, everyone,” he said loudly. “Before I make the experiment, there're twenty five atoms of carbon (碳原子), but after I finish it, there're twenty four atoms of carbon left!”

He stopped to watch the classroom and hoped his students would go on explaining it. But the young men looked at each other and nobody answered him. He had to ask,

    “What happens? What makes the atom lost?”

    The classroom was very quiet and none of the students looked at their teacher.

    “Who can tell us where it has gone?”

    Suddenly a soft voice came from the back row, “We did not see anybody leave the lab!”

    Mark Elliot Zuckerberg was born on May the 14th, 1984. He is the creator of the social media site Facebook. He was a star student at school, winning prizes in astronomy, maths and physics. He was also good at Classical studies. He studied Psychology and Computer Science at Harvard University, which is where he created Facebook. His invention led to his becoming Time magazine's Person Of the Year for 2010.

    Zuckerberg excelled in everything he did in his youth. He was captain of the school fencing team, spoke many languages and was a highly skilled computer programmer. While other kids played computer games, he designed them. He created his first network while in high school to connect all of the computers - in his father's dental surgery. He also built a media player which attracted the interest of Microsoft and AOL.

    Zuckerberg started at Harvard in September 2002. In his first year, he created Facemash, a Facebook predecessor (前身), which let students select the college's best looking people from a selection of photos.

    He launched Facebook from his Harvard room in February 2004. It was the start of a rollercoaster ride that would connect half a billion people worldwide and make him the world's youngest billionaire.

    Mark Zuckerberg is now one of the most influential people on the planet. He has dined with the president of the USA and regularly attends global economic summits and technology conferences. He stated: "The thing I really care about is the mission, making the world open." In 2010, Zuckerberg signed a promise, in which he promised to donate at least half of his life wealth to charity.

    Fern loved Wilbur more than anything. She loved to stroke him, to feed him, to put him to bed. Every morning, as soon as she got up, she warmed his milk, tied his bib on, and held the bottle for him.  Every afternoon, when the school bus stopped in front of her house, she jumped out and ran to the kitchen to fix another bottle for him. She fed him again at suppertime, and again just before going to bed.  Mrs. Arable gave him a feeding around noontime each day, when Fern was away in school. Wilbur loved his milk, and he was never happier than when Fern was warming up a bottle for him. He would stand and gaze up at her with adoring eyes.

    For the first few days of his life, Wilbur was allowed to live in a box near the stove in the kitchen. Then, when Mrs. Arable complained, he was moved to a bigger box in the woodshed. At two weeks of age, he was moved outdoors. It was apple-blossom time, and the days were getting warmer. Mr.  Arable fixed a small yard specially for Wilbur under an apple tree, and gave him a large wooden box full of straw, with a doorway cut in it so he could walk in and out as he pleased.

    "Won't he be cold at night?" asked Fern.

    "No," said her father.  "You watch and see what he does."

    Carrying a bottle of milk, Fern sat down under the apple tree inside the yard. Wilbur ran to her and she held the bottle for him while he sucked. When he had finished the last drop, he grunted and walked sleepily into the box. Fern peered through the door. Wilbur was poking the straw with his snout. In a short time he had dug a tunnel in the straw. He crawled into the tunnel and disappeared from sight, completely covered with straw.

    Fern was enchanted. It relieved her mind to know that her baby would sleep covered up, and would stay warm.

    Travelling can be a fun way to gain life experiences, especially during a week-long school vacation. But what if you're a student and don't have enough money for a trip? Don't worry.

Here are some useful tips.

    Save: This probably is the most important preparation for travelling. Cut expenses to fatten your wallet so you'll have more choices about where to go and how to get there.

    Plan ahead: Don't wait until the last minute to plan your trip. Tickets may cost more when bought on short notice. Giving yourself several months to get ready can mean security(安全)and savings.

    Do your homework: No matter where you go, research the places you will visit. Decide what to see. Travel books will provide information on the cheapest hotels and restaurants.

    Plan sensibly(明智地): Write down how much you expect to spend for food and hotels. Stick to your plan or you may not have enough money to cover everything.

    Travel in groups: Find someone who is interested in visiting the same places. By travelling with others you can share costs and experiences.

    Work as you go: Need more money to support your trip? Look for work in the places you visit.

    Go off the beaten path: Tourist cities may be expensive. You may want to rethink your trip and go to a lesser-known area. Smaller towns can have many interesting activities and sights.

    Pack necessary things: The most important things to take are not always clothes. Remember medicine in case you get sick and snacks in case you can't find a cheap restaurant.

    Use the Internet: The Net can help to save money. Some useful websites include www. Iravelocity.com, www.bargains-lowest fare.com and www.Economy travel.com.

    By planning sensibly, even students can enjoy the travel. Your travel experiences will be remembered for a lifetime.
