Debbie and Simon have part-time jobs at a travel company. One day, well-dressed lady entered the office and went to Debbie help. Debbie gave her a (cheer) greeting at once. But there (be) something wrong with Simon, because customers preferred to choose Debbie instead of (choose) him and he even didn't get a chance (speak).
Then Mr Yang taught Simon to improve his body language and try to give people a good (impress). So Simon decided to improve his body language. (improve) body language was not so hard. He sat up straight tried smiling at people. Later, a beautiful girl entered, walked over to Simon, and then left with a smile. Mr Yang came over but finally (find) that the girl was Simon's sister.
Many people have dogs at home as pets. If a dog is happy, then he may want to meet you or play with you. If he doesn't feel happy, then he would rather stay alone. But dogs can't talk. How can you tell how your dog is feeling? By his body language.
If your dog's head and back are lowered, his ears are down and his eyes are narrowed, and his tail is between his legs, then he is fearful. You may touch him gently to comfort him. If your dog's ears are up, his eyes are bright, and he wags his tail rapidly (快速地), he is very happy. He may also hold his mouth open more or even pant (气喘) mildly. Then you can go and play with him freely. If he closes his mouth and looks serious as you get closer, then he has changed his mind. It is better to leave him alone until he comes to you. Remember, we are talking about dogs that you know. Be sure a parent is around to allow you to get close to the dog. Get away from strange dogs even if they seem friendly.
The most important clue (线索) is the mouth. If the dog's mouth is closed, then he is most likely to be not relaxed or happy, and he does not want you to touch or play with him right now.
