One weekend, a wife and a husband went to visit a shop in London. After they got back home, they couldn't find their camera. They thought the camera must be in the shop. After a few weeks, they went to that shop again and the boss gave their camera back to them.

When their picture of the camera came out, the husband saw two pictures he did not take. One is a man standing at the door of the shop. In his hand there is a piece of paper with some words on it “I find your camera”. The other is a boy with a piece of paper in his hand. There are some words on the paper too, “I take the pictures.”

    The snow lasted until last Friday. I opened the window this morning and saw the sun but I felt much colder.

    “You'd better go to work on foot, dear,” said my husband, “It is dangerous for you to drive.”

    I thought him right and agreed. It would take me about forty minutes to get to my hospital. There was about an hour left, so I started, with a bag of sandwich for breakfast. In the streets there was thick snow and ice and the traffic was less than before and people walked carefully. Suddenly I saw a car going fast. The driver tried to pass the crossing before the lights turned red. Maybe he didn't see two boys in the middle of the street. His car knocked down one boy and stopped just in front of the police box.

    People crowded around the boy at once. I rushed out of the gathering crowd(聚集的人群) and was going to look him over. But a man pushed me aside and said, “Step back, please. I^'ve had a course in first aid.”

    I had to stand and watch his ministrations(救助) for a few minutes. Then I said to him, “When you need a doctor, sir, I'm already here.”

    Death of science icon(巨匠)

    In modern history, there has perhaps never been a scientist as well-known as Stephen Hawking. Whether he was educating the world with his knowledge of the universe（宇宙）, or making fun of himself in TV shows like The Simpsons, it's hard to imagine what the world will be like but now Hawking is no longer in it.

    On March 14, the British physicist passed away at his home in Cambridge, England. Since then, many people have expressed their sadness in public, including British computer scientist Tim Berners-Lee, who invented the World Wide Web. “We have lost a great mind and a wonderful spirit,” Berners-Lee wrote.

    Hawking was an icon for many reasons, but he will be best remembered for his work in the field of science. Building on German scientist Albert Einstein's work, Hawking explained his belief that space started with the Big Bang, and will end with Black Holes. This idea kicked off a series of scientific studies including into the origin of the universe itself.

    Besides his work in science, he also managed to overcome many difficulties in his personal life. While studying at Cambridge University, he got a serious illness at the age of 21. His illness left him disabled and he was told he only had a short time to live. However, as we all know, he went on to become one of the greatest minds that the world has ever known.

    Hawking leaves behind a great legacy(遗产). His book A Brief History of Time: From the Big Bang to Black Holes that came out in 1988, became one of the world's best-sellers. He may no longer be with us, but Hawking will continue to inspire the world for generations to come. As he once said himself, “Look up at the stars and not down at your feet.”

    One day, I got off the train and was waiting for my ride .Suddenly I had an inspiration (灵感). I looked around and found a pen, but there was no paper. I sat down sadly for a few minutes. Then I looked around again. Finally, I found a dollar bill in my wallet. Although there was very little space to write on, I could write something.

    I took my pen and wrote something like this," This is a very special dollar. I give it to you with love. Do not keep it. Do not spend it. Pass it on. Give it to someone else with love, and watch it be passed on."

    I then decorated the bill with hearts and tried to fill it with as many good wishes as I could.

    There was a woman sitting near me. She was also waiting for a ride. She seemed a little bit worried. So I walked up to her and gave the bill to her

    The woman couldn't know what I was doing at first. And then she took a second look and read it. Suddenly she was not worried and she was happy. Also, she gave me a big huge and thanked me.

    I knew that if this was the result from just one person, then this wave of warmth would probably go on.

    My ride came, and we drove off. But I thought this was not the end of the story.

    Tony, a nine-year-old kid, is sitting at his desk when suddenly he wets(尿湿) his pants. He thinks his heart is going to stop because he can't possibly know how this has happened. It has never happened before. He knows the after-effect (后果)—When the boys find out, he will never hear the end of it. When the girls find out, they'll never speak to him again as long as he lives.

    Tony puts his head down and say to himself, "Oh, no. What can I do? I need help now!"

    He looks up and notices the teacher coming, with a look in her eyes that says he has been discovered.

    As the teacher is walking to him, a classmate named Emily is carrying a glass that is full of water. Emily falls down in front of the teacher and drops the glass of water in Tony's pants. Tony seems to be angry, but all the while he is saying to himself, "Thank you, dear! Thank you, dear!"

    Now all of a sudden, instead of being the person that everyone laughs at, Tony is the person of sympathy (同情). The person that everyone laughs at should be him, but now it is Emily.

    She tries to help, but they tell her, "You've done enough, you stupid!"

    At the end of the day, as they were waiting for the bus, Tony walks over to Emily and says in a low voice," You did that on purpose, didn't you ?"

    Emily says back in a quiet voice, "I wet my pants, too."

    Look at the boy. His English name is Frank Smith. His Chinese name is Wang Lei. He is from England. He is 12. My name is Li Dong. David is my English name. I am from Qingdao, Shandong Frank and I are in grade seven. But I am in class Four and he is in Class Five. We are good friends. He often helps me with my English.

    These are our schoolbags. They are black. You can see two pens, a ruler and four books in Frank's school bag. In my schoolbag, there are three pens, two rulers and five books
