10. The boy with his two dogs ________ in the yard when the storm hit the city.

The little wolf (狼), White Fang, made an enemy (敌人) of the dog, Lip-Lip. Lip-Lip attacked (攻击) him whenever he could. He was bigger and stronger than White Fang and always won their fights. White Fang knew that he could not win a fight against Lip-Lip. He thought that he had to do something else to teach the dog a lesson.

One day, he was playing at a river bank when he saw Lip-Lip come. He suddenly got a good idea. He pretended to be hurt and unable to run fast. When Lip-Lip ran after him, he led Lip-Lip to the place where his mother stayed. When Lip-Lip got close to her, she turned Lip-Lip over and bit (咬) him until she let him go, but White Fang had a bigger problem.

Lip-Lip was the leader of the other dogs. They followed him and obeyed him. None of them would become friends with White Fang. Whenever he came near them, they attacked him.

①He was never allowed to play with the other dogs. This made him unhappy and angry. He often forgot how to behave (表现) well.

②Several days later, White Fang saw a man take his mother in a small boat. He tried to follow them. He jumped into the river and swam after the boat. Another man came after White Fang in his boat. He lifted White Fang out of the water. White Fang tried to get away from the man, but the man hit him and threw him into the boat.

③White Fang was now very angry because he wanted to be with his mother. He forgot how powerful (力量大的) men were, and he bit the man. The man was so angry that he beat White Fang again and again. The man hurt him badly.

White Fang finally learned that he couldn’t bite a man because if he did, he would be beaten badly.

Nowadays, camping is popular among young people. It’s a great way to be outside and enjoy the nature. Whether you like to be in the forest, mountains, or by the river, you are sure to have a wonderful experience when you go camping.     21     Fire may be dangerous, so just use it only when you must. Make sure to put the fire out when you don’t use it. Or it may cause a fire.     22     If you talk loudly, you may disturb (打扰) other people, and you will also miss the chance to see wild animals outside.     23     If you put up your tent in other areas, you may get into trouble. Remember to do it for your safety. Don’t forget to take your camera, or you will miss the wonderful natural wonders. Later, you’ll understand how nice they are.     24     People often get lost in the forest. It’s a good way to take a map that helps you to get the right direction (方向).     25     Maps and GPS can help you find the way easily.

A few years ago, my husband and I were on an island for a long weekend with our 3-and 4-year-old daughters. As we went back and talked about what to do next, our girls     31     in and told us exactly what they wanted to do. “We want to go to the     32     museum,” said Ariela and Eliana.

    33     we walked into the main area of the museum, we saw thousands of beautiful butterflies. They all flapped(扇动)their colorful wings.

My girls were jumping up and down, and I knew we had made the     34     decision to come to the museum. They were     35    .

I turned to our museum tour guide because I was curious, and asked, “How long do butterflies live?”

She said, “ About ten days.” “What can butterflies do in ten days?” I asked. The guide     36    , looked at me, and said, “They make the world a more     37     place.” “Wow,”I said, “I never thought about butterflies like that. Thank you.”

After we said goodbye, I couldn’t stop     38     what the guide had said. She was right. We all have something to offer the world with the limited (有限的) time we have. When we focus our gifts on     39     each other every day, we can make a difference.

How thankful it is that you can have the influence (影响) on your family, friends and neighbors.    40     a butterfly, you have your own way of making the world a little better for everyone.
