He found apiece of wood and wrote the following notice on it in big letters:“WHAT DO YOU THINK I GIVE AWAY PENCILS AND PAPER AND INK”He put up the notice in front of the shop window before he went to bed. He slept better than usual that night.The following day, many people came to the shop. Mr. Jones said good morning to them all with a bright smile and asked the first woman what she wanted.She chose some writing paper and a pencil. As soon as he had put them in her hands, she turned to leave the shop.“That will be thirty cents, please,” he said.“Why?” she asked in surprise.“That’s the price of the paper and the pencil.”“But your notice says it is free,” she replied.“Oh, no,” he said. “How can I make any money if everything is free?”She took him outside and showed him the notice. “It’s wrong, too,” she said. “Where’s the que stion mark (问号) after the word, THINK?”“There isn’t a question mark,” he said.“But there should be one.”“I’m afraid you’ve made a mistake,” Mr. Jones said. “You’ve read my notice in the wrong way.”“Not at all,” said the woman. “It’s qui te easy to read. It says: What do you think? I give away pencils and paper and ink!”“No,” Mr. Jones said. “You should read it like this: 39 And the answer to the question is: Certainly not! So you really have to pay me thirty cents, you see.”21. How did Mr. Jones probably feel that night?A. Confident.B. Guilty.C. Nervous.D. worried.22.

The woman paid the money unwillingly and left the shop angrily.D. Mr. Jones’s trick proved to be a long-time success and he got rich.BTeens want structure in their lives, which means they want their lives well-planned. To begin building structure, teens need love and trust. They need to know their parents are there to give them needed love and support (支持).Teens want to be sure that nothing can prevent parents from shouldering their responsibility for them—not their growing maturity (成熟), misbehavior, nor anger at something they have done. Teens want parents to keep control while allowing them to make some decisions.There are some ways you can help your teens create reasonable structure and remain close. One way is to spend time together. Parents often mistake their teens’ increased interest in friends for a disinterest in the family.Teens would like to spend more time doing things with their parents, but watching TV is not counted as spending time together. As your teens mature, it is important for you and your teens spend time alone together, one to one. Your teens need time to talk to you alone without any other family member present.Talk with your teens about their interests and concerns. Make sure you really show interest in what is happening. When talking with your teens, give full attention and do not stop them.The way to help your teens become adults is to let your teens into your world. Sharing your emotions and concerns with your teens is important. Avoid causing needless worry.Trust your teens. Don’t expect the worst. Hope for the best. Telling your teens you do n’t like their friends will cause the teens not to bring their friends home. If something should go wrong, believe that your teens didn’t do it on purpose.It is very important that you treat your teens with respect.Teens need the same respect adults show for total strangers. Don’t talk down to your teens.You need to be supportive of your teens. What may be a small problem to you may be troubling to your teens. Teens don’t have the experiences that adults have had. Let the teens know that you understand how much it hurts when something happens that is upsetting or hurtful to them. As they mature, they can look back at some problems they had and laugh at having been upset by something that now seems unimportant.The most important things to remember are: talk with your teens, listen to their worries and offer suggestions when needed. This will help your teens to live a well-organized life.26. According to Paragraph 1, teens ______________.A. can control themselvesB. expect direction and freedomC. don’t k now how to make decisionD. don’t have responsibility for the family27. The underline part “counted as” in Paragraph 3 probably means “____”.A. compared withB. used asC. connected withD. regarded as28. Parents can do the following things to remain close to their teenagers except _____A. give suggestionsB. spend time alone togetherC. trust their teensD. worry about the worst29. To help teens organize their lives, parents should__________.A. invite their teens’ fri ends homeB. leave their teens’ problems aloneC. share their feelings with their teensD. pay little attention to their teens’ daily lives30. What is the best title of the passage?A. Training Teens to Become Responsible Adults.B. Helping Teens to Build Reasonable Structure.C. Improving the Relationship with Your Teens.D. Stepping into Your Teens’ Secret Word.四、词汇(共10分，每小题1分)A.根据句意及首字母提示补全所缺单词31. He should stop w______ that silly earring.32. He doesn’t s_____ to have many friends. He always comes and goes alone.33.

In gym，they are allowed to take a class with dance music or play balls in the park.
