My sister and I went to an art museum last weekend. The museum was having a two-week show. Lots of very old artworks from two cities in Italy were on show.

    I liked one of the paintings best. The light on the woman's dress made it look as if she was really sitting there. A note on the wall told me about the artist and the painting. I was also interested in a very old sculpture(雕像). Parts of it had broken off. But I could still see how the man looked.

    There were quite a lot of paintings in the museum. Some paintings were stored away (保存). We saw them on the computer. The computer had a note about each painting and artist.

    After enjoying the artworks, we went to a room with costumes (戏装) in the museum. There my sister dressed up like one of the people in the old paintings. That was her favourite part of visiting the museum.

    In the museum, we also made art ourselves. I drew some flowers. And my sister drew a cute cat.

    At last we went to a gift shop in the museum. My sister chose a book for kids, and I chose a little sculpture.

    My sister and I were tired, but we had fun. I hope there can be more shows as exciting as this one in the museum.

    Baseball is my favourite sport. It is fun to play, and it is fun to watch.

    I went to my first baseball game with my grandparents when I was 6. It was really wonderful.

    We had a good time. I was happy to be with my grandparents. My grandfather made me love the game.

    My dad knew I loved baseball, so he gave me a baseball on my ninth birthday.

    When I was 12, my friend came to me and asked me to join his team and play baseball. From then on(从那时起), I got to learn more about baseball. I practised a lot and learned how to play better.

    My favourite player is Derrek Lee. Derrek Lee joined the Chicago Cubs in 2004. That year was a good year for him, but 2005 was his best year. One of my favourite things about Derrek Lee is that he is a very nice person. He never shouts at others. He always has a big smile on his face. He seems happy all the time.

    I can't remember when I started collecting rubbish. It might be when I got tired of(厌倦) seeing rubbish in the forest near my home. I used to love going there to play with my dog. But one day there was so much rubbish there that I became very unhappy.

    I decided I had to clean up the forest. I made my first trip to clean the forest that afternoon. I took a big black rubbish bag with me. Ten minutes after starting picking up rubbish, my bag was full! It had cans, bottles, broken glass and newspapers in it.

    I go to the forest four times a year to pick up rubbish. I often stay there for three hours. After each trip, I look at all the rubbish. If any of it is recyclable, I will keep it. It makes me feel great to do something for the environment. I will keep picking up rubbish until people stop dropping it.

    Jack thought himself a basketball fan. He watched quite a lot of American NBA basketball games. Not only did he watch them, he spent much of his free time playing on the court too. Then came the final year of his middle school. All of his regular teammates stopped showing up on the court because they were simply too busy preparing for the high school entrance exam to play. He was, of course, under much stress himself, like everyone else. A good exam result meant a good high school; a mediocre(平庸的) score meant a mediocre school. Much was at stake. However, he loved basketball so much that he still found time to play, this time with a group of guys who were said to have skipped classes(逃课) before.

    Some of his teachers started worrying about him. They asked his mother to go to school to let her know that Jack was hanging out with problem kids. When his mother returned home that day, she wanted to talk to Jack. Knowing the purpose of her visit to the school, Jack thought his mother would punish him for befriending those bad guys. To his surprise, his mother was not angry with him at all. She wanted to hear her son's side of the story. So Jack told his mother about what he knew of Simon and Peter. Simon's parents were badly ill; Peter's father had lost his job. They both seemed to Jack to be normal kids. Jack's mother thought for a moment, then went on to say that she was OK with her son playing with them and that she and her son should think of ways to help these kids. Soon Jack's mum introduced some part-time jobs to Simon and Peter, which they accepted. She believed in her son and cared about those who were less lucky.

    Jack's basketball friends and he have left for different places, but they still keep in touch. He knows Peter is now a manager of a local bank.  Simon is currently a freshman at a university. Sadly, it is impossible to get together to play basketball again, but whenever they get on the phone, they talk about it all the time.

You might have seen beautiful rainbows in the sky before. They form when sunlight falls on water drops in the air. But in fact, moonlight can also create rainbows in the same way. They are called "moonbows". They are similar to rainbows, but they are created by moonlight. 

Moonbows are more unusual than rainbows. Different weather and astronomical (天文学的) conditions have to be just right for moonbows to be created. The moon has to be very low in the sky — only 42 degrees from the horizon (地平线). The moon has to be a full moon or nearly full. The sky must be very dark for a moonbow to be watched clearly — any bright light can obscure it. Water drops must appear in the air in the opposite direction of the moon. Moonbows appear on the opposite side of the moon and usually look white to the human eye. This is because their colors are not bright enough to be noticed by the human eye. 

Moonbows more often appear in some locations around the world. Most of these locations usually have waterfalls, which create thin fog in the air. Some of these locations are the Yosemite National Park in California, Cumberland Falls State Resort Park in Kentucky and Waimea in Hawaii, US. 

Moonbows do really happen. So at a certain time and a certain place, when a moonbow happens to appear, you can't miss it if you're right there.
