There are many wetlands (湿地) in China ‒ and some of them have become the world's important wetlands. The Chinese Yellow Sea Wetlands are {#blank#}1{#/blank#} them. They are in Yancheng, Jiangsu Province. They are {#blank#}2{#/blank#} to many different kinds of animals. The world's {#blank#}3{#/blank#} Milu deer nature reserve (自然保护区) is on these wetlands. More than 700 Milu deer live there. There are not many red-crowned cranes (丹顶鹤) {#blank#}4{#/blank#} in the world, but every winter, you can see some in the red-crowned crane nature reserve in the Yellow Sea Wetlands.

    The {#blank#}5{#/blank#} in the wetlands is neither too high nor too low. There is  {#blank#}6{#/blank#} rain and sunshine, too. They are a good place for wildlife. But offering food and shelter for special kinds of animals is not the  {#blank#}7{#/blank#} reason we need to protect wetlands. Wetlands are important {#blank#}8{#/blank#} they also prevent floods. But some people want to {#blank#}9{#/blank#} the wetlands to make more space for farms and less space for wildlife.

    More people are beginning to realize the {#blank#}10{#/blank#} of wetlands and wildlife. Every year, on Feb 2, many activities are held to teach people about the wetlands.

    America is a mobile society. Friendship between Americans can be close and real, yet disappears soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while, then no more, If the same two people meet again by chance, even years later, they pick up the friendship.

    This can be quite difficult for us Chinese to understand, because friendship between us flows more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families.

    Americans are ready to receive us foreigners at their homes, share their holidays and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily.

    Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don't show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. Americans, however, express their welcome at home. But they truly cannot manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves to be treated hospitably.

    For Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home!

You will probably know the feeling—it is time for school, but your eyes are only half-open. Your arms and legs are heavy and your brain is still asleep. So what can you do to stay awake when you are tired? {#blank#}1{#/blank#} 

Eat breakfast

Breakfast is the most important meal of the day, but it is also the easiest to skip（省略）. Start your day off with a healthy breakfast. {#blank#}2{#/blank#} They can keep you from feeling hungry and tired in the morning. 

Use water

When you are tired, water is your friend. {#blank#}3{#/blank#} It is even better than drinking lots of coffee. Coffee is fine in the morning, but it is best to drink water after lunch to make sure you can get to sleep. 

Get moving

 {#blank#}4{#/blank#} A few minutes of physical activity can improve oxygen circulation（氧循环）and keep your body active. It doesn't need to be anything difficult. A few push-ups and a short walk may be a great help. 

However, there is still something that you can't do when you are tired. {#blank#}5{#/blank#} Besides, if you find you are often feeling tired and you are not sure why, it is a good idea to speak to a doctor. 

One day, a successful businessman was getting ready to go to his office in the morning. When he opened the door of his car, a stray dog(流浪狗) sleeping under his car suddenly came out and bit his leg! He was angry and threw a rock at the dog, but he was not able to hit it. 

Upon reaching his office, the businessman called a meeting of his managers. During the meeting, he took out his anger on his managers. His managers were upset about this, and took out their own anger on the employees(员工) working under them. Gradually, the businessman's anger spread through the whole company. '

The businessman was still angry after returning home. His wife opened the door. She asked him, "Why are you so late today?" The man shouted at his wife, "I didn't go to the office to play soccer, I went to work. So don't ask me such stupid questions!" His wife was upset about being shouted at for no reason. She turned her anger on their son, who was watching TV. "This is all you do. You have no interest in studying! Turn off the TV now!" She yelled. 

The son became upset as well. He walked out of his house and saw a dog passing by. He picked up a rock and threw it at the dog angrily. The dog ran away, barking in pain. 

Sometimes, when we are angry about something, we might take out our anger on others who are not to blame for our mood. This is not fair to others. We should learn to control our anger. 

Hello, I'm Bob. I'm 12 years old. I am at school now. I want to say something about myself. 

Playing volleyball is my hobby. I like it very much. I always play volleyball with my friends after school. It's relaxing for me. I have five volleyballs. They are under my desk. And I like to watch volleyball games on TV. 

I have eggs, milk and some fruit for breakfast. For lunch, I have noodles and some salad(沙拉). For dinner, I like chicken and some vegetables. I don't eat ice cream. It's not healthy. My favourite food is fruit and vegetables. I think they are good for our health. 

I'm healthy because I like to play sports and eat healthy food. What about you? Can you tell me about your hobby and eating habits?
