Janet is my best friend. One day, however, I nearly ended our friendship. I remember that day clearly.
We were 1 in the classroom. The teacher was giving us the results of a maths exam. I had done badly. I felt so 2 that I wouldn't talk to anyone. At lunchtime, I still stayed in the classroom alone. Suddenly, I heard a 3 . It was Janet. "You look very unhappy," she said. "What's wrong?" I looked at her for a while, but said 4 . I knew Janet had a good mark in the exam. I thought she was laughing at me. She kept asking me questions, "Is it because of the exam? Do you want me to tell you the right 5 ?" I looked away from her. When I looked up again, Janet had gone. I didn't know 6 to do. I looked for my paper everywhere, but couldn't find it.
In the afternoon, Janet came up to my desk and 7 me my exam paper back. I looked at it and got a big 8 . Janet had written the right answers next to each of my mistakes. How 9 she was! My face turned red. I wanted to hug her, but I only held her hands and said, "Thank you. " That afternoon, when Janet and I were on the way home, I felt quite happy and thanked her again. We are 10 best friends now.
Is the world too crowded? Well, that's a hard question to answer. It's a matter of the perspective (视角). In Montana, you might drive a mile in any direction and might not see another human being. In Macao, 60,000 people live in every square mile!
What is true is that the world's population doesn't stay the same. It has been increasing fast. That's in part because in each generation (代)there are more people who then have children than the last generation.
Five hundred years ago, the population of the world was about 460 million. In 1900, the world's population was under 2 billion (十亿). Right now it is doubling every 40 years. That means, if this rate of growth continues, when you are a parent, there will be twice as many people on earth as there are now. Soon the world's population will probably reach 8 billion. Some people worry about that! But there is a lot of disagreement about just how many people on earth means too many people. But everyone agrees that the more people there are, the more resources (资源) the world needs to offer and the more need there is to think carefully about how we live and use the earth's resources.
Exercise improves not only your appearance, but also your health. Health experts advise people to choose physical activities that they find interesting. So, what are some of the most popular forms (形式) of exercise in the USA?
Walking is on the top of the list. It is considered to be the ▲ way to get exercise. You can walk at any time and any place. Walking is also said to be the least harmful to the knees and feet. So, it's a perfect choice for the old.
Another popular form of exercise is jogging. In the 1960s, Bill Bowerman brought jogging to the USA. He did so after seeing the popularity of the activities during a trip to New Zealand in 1962. He started the first jogging club in America. He also helped found Nike.
Swimming is also very popular. It is one of the most popular sporting activities in America. When one is swimming, the whole body is put to work. It is said that swimming is good for people with special needs, like pregnant (怀孕的) women.
Dancing can also be a fun way to exercise. This is especially true for those who see exercise as something that they should do. A dance fitness programme called Zumba has grown in popularity in recent (最近的) years. It was created by Alberto Perez in Colombia in the 1990s. In 2001, he brought the programme to the USA. Since then, it has spread around the world.
How to Become a Radio DJ
No family wants its home to catch fire, but it's good to plan for a fire just in case. Talk with your family about what to do if a fire starts. Everyone should have a plan for getting out of the house. Be sure to choose a safe place to meet after everyone gets away from the fire.
What should you do if there is a fire? First, let people know about the fire. Yell(叫喊) the word "fire". Knock on the walls with your hands.
Then feel the door of your room. If the door is warm, don't open it. If it's cool, open it just enough to look out. If you see fire or much smoke, close the door fast. If you can't see fire or smoke, you can go out of the door. Shut the door behind you. That will slow down the fire. Now find a way out. Stay away from the smoke. The air is the best near the floor, so it may be the safest to crawl(爬行) when you leave the house.
If you can't leave your room, close your door. Cover the crack (缝隙) under the door with clothing. Then open the window or break the glass with a chair. Crawl out of the window carefully. If the window is high off the ground, don't jump! Wave a towel out of the window, and yell for help. When you get out of the house, run to the place where you and your family chose to meet.
