Noise pollution is doing much harm to our health now. Noise, in fact, is unwanted sound and is a kind of invisible (无形的) killer. More and more students enjoy listening to music very much. When they listen to MP3 players, they like to turn up the volume (音量). Some people love listening to loud music. Furthermore, while watching TV, they keep the volume up. But they haven't realized that the noise is weakening their hearing. In fact, the noise not only influences each member in the family, but also makes a difference to the comfort of neighbors.

Noise pollution is a source of increasing misery (痛苦) to people in our society. If people are often disturbed by it, they may feel uncomfortable or upset. What's worse, the noise can make people mad sometimes. If a worker works in a printing factory for too long, his/her hearing loss is much faster than a common person working in a quieter environment. So everybody must pay more attention to noise pollution. Generally speaking, the following four types of noise should be watched out for:

    ◆Noise in the street

    ◆Construction site (建筑工地) noise

    ◆Noise at work

    ◆Transportation noise

    I think the local department (部门) should take measures to control the noise levels, but it's everybody's duty to keep a quiet environment.

    When was the last time you saw three men running down a forest trail（小径）in the rain wearing flip-flops（拖鞋）？That's what my friend Brandon, Josh and I were doing last autumn. We were looking for a waterfall（瀑布）.We didn't have much time to get to the waterfall and back, so we were running. We were wearing flip-flops to prevent our shoes getting dirty.

    It was raining, but lightly. It kept us cool as we climbed over giant stones and through a shallow（浅的）stream. We followed red arrows（箭头）and crossed that stream several times, walking on toward the promised waterfall. Time was not on our side, however, and we were forced to turn around. As we started back, we looked at the shallow stream we had just crossed. Where did this rushing river come from? That was when we realized a flash flood was around!

    In the few minutes the water rose at a fast speed. Now there were no big stones to be seen-only what looked like lumps（隆起）covered with rushing water. We had no choice but to move our way back carefully in the rushing water -in flip-flops. We had crossed the stream not once or twice, but six times in search of a waterfall that we never even reached!

    With most of the crossings, we needed each other's help if we didn't want to be washed away by water. Wet all over, we felt relaxed after we made the last crossing.

    "My dad always told me to keep off a river when travelling in the rain." Josh said as we hurried back down the path.

    "Why didn't you tell us that earlier?" I laughed.

    "Would it have made a difference?" came the reply.

    He had a point.

    Years ago, Tareq and his family left their home in Bangladesh to New York City, US. Tareq was only 12 years old then.

    In Bangladesh, Tareq's dad was a farmer. He worked hard for little pay. Every day, Tareq walked 6 kilometres to school. After school, he had to work on the farm.

    But Tareq had fun. He loved singing and playing cricket (板球) with his friends. One day Tareq's dad told him they would move to New York City. Tareq's dad found a new job there, and he thought life would be better there.

    In his new school, Tateq tried his best to understand his teachers, but it was quite hard. Also, he had few friends.

    Things changed when he started high school. His high school had students from 30 countries and a cricket team. Tareq was excited to join the cricket team. He was happy to be with kids who loved the game as much as he did. He practised before and after school. "Playing with the cricket team was the first time I felt accepted in America," he said. "When you play, it doesn't matter what grade you' re in or what language you speak."

    During his second year in high school, Tareq was named the cricket team' s most valuable player(最有价值球员).

    Tareq will go to university next year. He said, "Most universities don't have a cricket team. But that's OK, because cricket was there for me when I needed it most."

    Helen Keller was born in 1880 in the USA. When she was about 19 months old, she got very ill. After many weeks, the doctor told her parents, "Your daughter is better, but now she can't see and she can't hear." Her mother and her father were very sad. After a few years, things got worse. There was no way for Helen to speak to other people. She heard nothing. She didn't understand anything.

    Then one day a teacher came. Her name was Anne Sullivan She lived with Helen and her family. The teacher helped Helen learn words. Helen was a very clever child and soon she learned to spell her first word. When she was older, she went to college.

    Helen was a very famous woman when she died. The world remembers her today as a brave and wonderful person. She was blind and deaf, but she found a way to see and hear. It helped many people in the world.

    It's March, 2050. Frank and Mary Smith wake up in their comfortable house in the morning and turn on the bedroom computer to get the latest news. They get used to reading The Times over the years. The only difference is that they changed to electronic newspapers many years ago.

    After breakfast, as they watch the screen, Mary orders the household robot to make coffee for them. Frank is a computer engineer, working for several companies. He goes into the study to take part in a video conference with his partners around the world.

    Mary takes a quick look at the shopping channels at home before beginning the video call to talk to her assistant. She also has a job and she is doing medical researches.

    Frank and Mary have one daughter, Louise, who also has her own work station at home. She goes to school only one day a week, mainly to play with other students. Louise is studying Chinese at present. Chinese has become an important language in the world.

    According to the family doctor, Louise will live to at least 130 years old. Her wish is to work for a few decades(十年)and then spend her time on music and painting.

Dear Jenny,

    How are you? I am visiting my cousin Howard in Australia. It is hot in Hong Kong but it is cold in Australia in June. When it is summer in Hong Kong, it is winter in Australia. It is snowing heavily now. I like snow a lot and it is a white world outside. I will play with my cousin in the snow this afternoon. We want to make a snowman. I think it is very interesting!

    I like my cousin's house. It is big and there is a beautiful garden. We can play ball games there. My cousin's neighbors are friendly, but they cannot speak Chinese. I talk with them in English. See you next month.

Yours,

Tony
