Hello, everyone!  1 to Class 3. I'm your new English teacher, Mr. Yang. Now let me tell you our class  2. First, you can't be late 3 class. You must 4 on time. Second, you must bring your English books and notebooks to every 5. Third, you must   6 English during the pair work activities. If it's 7 for you, you can ask me for help. Fourth, if you have any  8, you must put up your hands(举手). You can't talk or stand up without permission（未经许可）. These are all the rules. They are good for you,  9 you must follow them. I hope we can have a good 10 every day.

    The world is in danger. At one time there were 1,300 different plants, trees and flowers in Holland, but now only 860 remain(剩余). The others have been destroyed(破坏) by man. We are changing the earth, the air, the water and everything that grows and lives. We can't live without these things. If we continue doing like this, we will destroy ourselves.

    What will happen in the future? Perhaps it is more important to ask "What must we do now?" The people who will be living in the world of tomorrow are the young of today. A lot of them know that conservation(对自然环境的保护) is necessary. Many are helping to save our world. They plant trees and protect animals in forest. In a small town in the United States, a large group of volunteers cleaned the banks of their rivers. Young people may hear about conservation through a record called No One's Going to Change Our World. It was made by the Beatles, Cliff Richard and other singers. The money from it will help to protect wild animals.

    When the weather is hot, you go to a lake or an ocean. When you are near a lake or an Ocean, you feel cool. Why? The sun makes the earth hot, but it cannot make the water very hot. Although the air over the earth becomes hot, the air over the water is still cool. The hot air over the earth goes up. Then the cool air over the water moves in and takes the place of the hot air.

    Then you may ask, "Why is the ocean full of salt?" Scientists will say that the salt comes from the rocks. When the rocks get very hot or very cold, they crack (爆裂). Rain falls into the cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. And then you may doubt, "But the ocean does not get more salty every year. Scientists are not sure about the answer to this question.

    We know a lot about our world. But there are still many answers that we do not have, and we are curious about them.

    What is the hardest sport in the world? Some people say it's boxing (拳击), because boxing is dangerous and boxers have to be strong and fast. Other people say the hardest sport is soccer.

    However, most people say the hardest sport is the triathlon (三项全能运动). A triathlon is a race that includes three sports. First, racers swim. After that they ride bicycles and finally they run. In the most common triathlon, racers swim 1.5kilometres, bike 40 kilometres, and run 10 kilometres. The winner is the person who finishes the race first.

    There is another kind of triathlon too. It is called the "Ironman Triathlon (铁人三项)". This triathlon is much longer. People who finish this triathlon are called "ironmen" or "ironwomen". This is because these people are so strong that their bodies are just like iron (铁).

    In the past, there were other races including three sports. However, they didn't use the word "triathlon". That word was first used to describe a race in California in 1974.

    Triathlon racers have to train very hard for their races. Many of them swim and run. A lot of people also do things like yoga (瑜伽). They have many different ways to prepare, but they all have the same goal. They want to be in perfect shape.

    To be an ironman or an ironwoman, you have to be strong and smart. You should know how to save energy during the race.

Have you ever wondered what an American high school is really like? This article will describe a typical (典型的) high school and its students.

A typical American high school has several large buildings and enough space for about 1,500 students. Every student is given a locker. When students first arrive at school, they go straight to their lockers to put away or get their textbooks and to hang up their outdoor clothes. As American textbooks are expensive, students would rather loan (租借) than buy them. Students must pay back if they lost any of them.

American students have different types of school transport. They usually take a yellow school bus or walk to school if they live close enough. Sometimes their parents drive them to school.

When they turn 16 years of age, most take a free driving class at school for one term. If students' exam passing grades in the class and also pass their state driver's exam, they can begin driving themselves to school.

Each day, students take six or seven classes. They must take science, math, English and social studies. They can choose art, homemaking, fashion design and other classes. In some schools students are required to take one or more of the following special classes: health education, physical education or foreign language studies. Students move to different classrooms for each subject. This is because cache teacher has their own classroom. There is a five-minute break between classes, to give the students the time to hurry to their next class.

The regular school day usually ends early in the afternoon. After school more than half of the students take part in after-school activities. These activities include sports, specially football, basketball, baseball and soccer or clubs, such as yearbook, speech, school newspaper, photograph or student government.
