Air pollution influences our health in many ways. No air means death. Though we can't see it, there is air around us. Air is everywhere and it gives a life to every living things. But bad air makes people ill. In the city, there are a great many people and there are too many cars running on the road. The cars send out bad gases (气体). There are many factories too. From the chimneys (烟卤) of these factories, we get the smoke usually in black colour. Every day we breathe it in and out. This makes us feel sick. When people talk about air pollution, they are usually thinking about outdoor air pollution. But a lot of air pollution comes from indoor activities such as smoking and cooking. Indoor air pollution can hurt people's eyes, noses and throats. So air pollution, both indoor and outdoor, can also lead to lung cancer (肺癌) and heart disease.

    Everyone should help fight against pollution. In order to keep us healthy, we have to go out to the countryside to breathe more fresh air. Or we can climb up hills to get more fresh air.

Bex Lindsay's dream was to be a host. From a young age, she was very 1 in radio. In her childhood she often pretended (假装) to host her own shows on Bex Radio while 2 her parents' CDs. At that time Lindsay wanted very much to work at Fun Kids, a radio station 3 young listeners, so she sent them a strange recording, hoping to be accepted.

"In the old host-to-be performance, the final thing you were 4 to do was to jump on a trampoline (蹦床) while interviewing 5, "she told the reporter, "I didn't have a trampoline and I didn't want to do it in front of anyone else, so I interviewed myself while jumping on my bed, having the recording made. "

Lindsay's recording really 6 and she was asked to host the Sunday breakfast show. Now she hosts a popular program and she loves radio more than ever. She says, "My 7 as the host is kind of to be a listener, so I will ask questions that other people would want to ask."

When she is asked how she has been 8, Lindsay says, "First of all, keep the dream in your mind and 9 give up. "She adds, "Hosting isn't about how high up in the world you are; its about having a good 10 and a good idea. Go and do it."

One Thursday afternoon, when I was in Grade 7, a new boy came into my classroom. He was short and thin. He walked up to the teacher and told her, very seriously, that he was new. His name was Christian. He sat down, took a look at me, and then looked away. I didn't think he was very nice and I was sure he wasn't the type I would like to become friends with.

During that year, I didn't talk to him much, but he smiled at me when our eyes met, always shyly. He never ate lunch with anybody, and he never talked to anybody but me.

But one day I joined those unkind kids who were making fun of him. We made fun of him though I thought it was wrong. 

"Haven't you got any friends? " a kid asked Christian, who had walked past us alone, head down.  "No, he hasn't got any friends. He's too stupid and shy. " I said. Then Christian looked up at me with the saddest dog eyes I had ever seen. I felt very sorry at that moment.

That night, I couldn't sleep because I couldn't get Christian's face out of my mind. In the weeks that followed, he never met my eyes in class and never smiled at me. It was really hard for me to decide to write him a note asking him to forgive（原谅）me. But I thought I should. 

The next day in class, I wrote him a note telling him how sorry I felt. About five minutes later, I turned and saw tears in his eyes. "You will never realize (意识到) what your apology（道歉）has meant to me, Jimmy, "he said to me. "I hope we can become friends. "

We had lunch together that noon and we had the best talk I had ever had. Over the years at high school, we were close friends.

When I think back, I realize that, if I had not apologized, I would never have known what a lovely person Christian was.

Apologies can really change your life, so never miss the chance to tell somebody you are sorry.

We usually have three meals a day——breakfast, lunch and dinner. Different people have different food for breakfast. Some children tell us about their breakfast food. 

Simon is an American boy. He usually eats cakes and drinks milk with sugar (糖) for breakfast. He loves sugar. He is short. He doesn't like to drink juice for breakfast.

Jack is from the UK. He usually has bread and a glass of juice for breakfast. His favorite is apple juice, but his family like orange juice. They usually have eggs and hamburgers. 

Lucy is a Chinese girl. She usually has soup (汤) and baozi with meat for breakfast. She doesn't have bread and cakes for breakfast.
