One day Jack met his good friend Sue in the park. A dog was looking up at the woman beside her.
　  Jack walked up to Sue and said, “Hello, how are you? May I sit and talk with you for a moment?” “Of course, please sit down,” Sue said. Jack sat down next to Sue on the bench, and they talked quietly together. The dog continued to look up at Sue, as if( 似乎) waiting to be given some food.
　 “That's a nice dog, isn't he?” Jack said, pointing at the animal.
　 “Yes, he is. He's handsome. He's strong and healthy.”
“And hungry,” Jack said. “He hasn't taken his eyes off you. He thinks you've got some food for him.”
　 “That's true,” Sue said. “But I haven't.”
　　They both laughed and then Jack said, “Does your dog bite（咬）?”
　　“No, ”Sue said, “ He's never bitten anyone. He's always gentle and friendly.”
　　Hearing this, Jack decided to hold out his hand and touched the animal's head. Suddenly it jumped up and bit him.
　　“Hey!” Jack shouted. “You said your dog didn't bite.”
　　Sue answered in surprise, “Yeah, I did. But this is not my dog. My dog is at home.”
【小题1】Jack and Sue were ________.

If you get into the forest with your friends, stay with them always. If you don’t, you may get lost. If you really get lost, this is what you should do. Sit down and stay where you are. Don’t try to find your friends—let them find you by staying in one place.

　　There is another way to help your friends or other nearby people to find you. Give them a signal (信号) by shouting or whistling (吹口哨) three times. Any signal given three times is a call for help.

　　Keep up shouting or whistling always three times together. When people hear you, they will know that you are not just making noise for fun. They will let you know that they have heard your signal. They give you two shouts, two whistles, or two gun-shots (枪声). When someone gives you a signal, it is an answer to a call for help.

　　If you don’t think that you will get help before night comes, try to make a little house---cover up to the holes with branches (树枝) with lots of leaves. Make yourself a soft bed with leaves and grass.

　　What should you do if you get hungry or need drinking water? You would have to leave your little house to look for a river. Don’t just walk away. Pick off small branches and drop them as you walk so that you can find your way back. The most important thing to do when you are lost is—stay in one place.
