    I was traveling alone through the UK. To reach places that were off the public transportation map，I bought an old car, which cost most of my money. I couldn't afford to stay in the hotel, so I had to camp in my car for the rest of the trip.

    One morning I awoke in my old car on a country road in Ireland and saw a single house. The water in my thermos (保温瓶）had gone cold, so I knocked on the door of the house. A woman opened it. I asked her for some hot water. But she wouldn't let me get away with just that! I was invited indoors. She asked me to sit at the table and have breakfast with her family. They filled my thermos before I left.

I was greatly moved. And I decided to pass the kindness on. The other day I met a young man who had been driving around to look for a parking lot. He looked increasingly upset. I was glad that I was able to point one out to him. His thankful smile was the hugest reward (奖赏）for me.

    We often hear stories of animals rescuing people．But now someone has managed to return the favor．

    The event took place one snowy January morning Thomas Smith was walking his dog，Jack，in the park．"As I was walking，I just saw Jack running onto the ice towards the ducks in the middle，and then he fell into the water and couldn't climb out，"said Smith．He realized he had no choice but to try and save his dog．"someone else told me the lake was only one﹣meter deep，but it was at least twice that．I had to break my way through the 6﹣cm ice．Finally，I got Jack by the neck，and pulled him out．I don't think I have ever felt so cold by the time we got back to dry land．And when we got there，everyone was asking if Jack was okay﹣﹣﹣﹣﹣﹣no one was particularly worried，about me!"

    A neighbor，Julie Brown，saw it all happen．"The dog went onto an icy lake．All of a sudden，it started to go under．There were crowds of people around，and they were all shouting and screaming．Before I knew it，the owner Smith was in the water forcing his way through the ice．I can't begin to imagine how cold it was．Everyone was very nervous，but he was as cool as a cucumber﹣﹣﹣﹣﹣he just crawled back out，put the dog on its lead，and went home．"

    Many regard him as a hero，but Mr．Smith is quite laid﹣back about it．"Most dog owners are the same as me．They would do what I did without a second thought．But in the future，I'm going to make sure he's on lead near any ice ponds，Pets are members of our family．Would you do the same for them？

    "Colour, colour, colour!" are the words of the artist Eric Carle. Eric is like the king in the world of children's books. He has written over 70 children's books. His most famous book. The Very HungryCaterpillar, is common on children's bookshelves all over the world. What most people don't know is that Eric also makes art for adults, which is called "ArtArt". People didn't know about it, because he didn't show it to the public until he was 84 years old!

    Like Eric's children's books, his "ArtArt" is full of bright and clear colour. He says that he loves colour so much because he missed it during the war in Germany. Eric was born in New York in 1929, but moved to Germany with his family when he was 6. When he was 10, World War Ⅱ began. He noticed that all the houses and buildings in his town were painted grey, brown or dark green. It was a sad time, and it seemed like there was no colour anywhere.

    At the end of the war, "when colour came back", Eric explains, "I just loved it so much. I keep saying that I wish our eyes could see more colour. Colour is a very important part of my work."

    That's true. Eric paints bright colours on Paper, cuts out shapes, and then glues them onto another piece of paper. This method is called collage (拼贴画). In fact, it is what led Eric to his "ArtArt".

    Eric's "ArtArt" includes large collages as well as paintings, photographs and even costumes. In all these works, he uses all kinds of colours—everything from purple to light green to orange. Now that's a lot of colour!

    Mr. and Mrs. Smith live in a quiet village. Last weekend, they went to a busy city for vacation. Mrs. Smith was very excited, because she was a housewife.

    She stayed at home every day. It was boring.

    After they got to the city, they would like to go to the movies first and then have lunch at a restaurant. At night, they would stay at a five-star hotel.

    "Wow! The plan is so great. I like it!" Mrs. Smith said. Then they went to the movies. After seeing an exciting action movie, it was time for dinner. They went into a restaurant and had a lot of delicious food there.

    "It is a nice place!" said Mr. Smith. Then he put his hands into his pocket to get the wallet. But he found it was missing.

    That night, everything changed. They didn't spend a romantic time at the hotel. Instead, they had to go to the police station for help.

    For years I went to school by bus, so I met many "familiar" strangers. We took the same bus but didn't know each other's names. I used to think it was impossible for us to be true friends. How wrong I was! Smiles from the "nameless" people have changed my thought.

    The first time on the bus, I saw different faces. As days went on, we hatted like old friends.

    But I felt it a pity that I was unable to set up the same friendship with a silent girl in the front of the bus. Her old clothing suggested that she didn't have much money, but she always took a cup of water for the driver. I guessed she was a kind girl. But why did she sit in silence instead of talking with us? Why did she never reply to our friendly greetings? Couldn't she smile?

    Then, one evening, I got the answer. I walked to the park nearby and found the girl sitting alone under a tree, lonely and sad. I greeted her with the same warm smile that had shown to her all these months, but this time her face turned red, then a shy smile appeared. As soon as she began her first words, I understood why she hadn't spoken to us before. Talking was hard for her.

    I heard her story. Her parents worked hard somewhere. She lived with her disabled grandparents. She said, "I can't express myself very well. Most of the time, I can't say what I want to say I have no friends but. You always smile at me like an angel… so I also want to smile." That evening, we exchanged our names and we said goodbye like old friends.

    The smile is the key to opening the door of heart; it can break the cold walls in front of us.
