Unluckily, Jenny didn’t even have the 95 cents. As she crossed the street, she thought about doing her brother's housework, cleaning the floor, washing the dishes all month, but even then she would have only eleven dollars. Suddenly, something small and pink in the snow caught her eyes. Jenny walked over and picked it up from the snow. It was a beautiful wallet. She opened the wallet and found many dollars and a woman’s driver’s license in it. Jenny put the wallet into her bag quickly. She turned around and walked back. Jenny’s heart beat(跳动) fast as she went into the store. She had long dreamed about this moment, but something didn’t feel right. As she got to the Happy Hannah dolls, she pushed away her feelings. She grabbed(抓起) one and walked toward the checkout. As Jenny was waiting to pay, her mobile phone rang. It was her grandma. Jenny’s heart was suddenly filled with love and warmth when she thought of her. She put the doll down and answered the phone. “Hi, Grandma? I’m going to be a little bit late tonight...Alright...I love you, too.” Jenny left the store and walked all the way to 301 West Street. The woman who answered the door looked sad. “Here, I found this in the snow,” Jenny said. “Oh, good God! This is the money for the orphanage(孤儿院)! Thank you!” After doing her brother's housework for three months, Jenny finally got a Happy Hannah doll. She was so happy because she could play with her doll and look her grandma in the eye. 61.

The girl didn’t have a Happy Hannah doll in the end. D “You are what you eat” is a common English saying. It means the food you eat will become part of you. Many experts use it to tell people it’s important to have a good eating habit. For example, too much sweet food makes a person overweight. To avoid being fat, kids are told to keep off sweet food. However, a team of American scientists have discovered something new about eating sweet food. 　　“When we say some people ‘sweet’, we mean they are kind and friendly to us. Perhaps this word can help us learn more about people’s feelings and acts.”said Brain Meier, a scientist from the study team. “Taste is something we experience(体验) every day. What we have done is to find whether we can know someone’s character and behavior depending on their taste.” In one of their experiments(实验), college students were asked questions about their characters, for example, they were soft-hearted or not. Then they were asked to make a list of their favorite food. According to their answers, the scientists found that the students who liked sweet food were nicer. 　　In their another experiment, the scientists found that people who preferred sweet food such as cookies and chocolate helped other people in need, but those who ate non-sweet food such as chips weren’t. For example, people with a sweet tooth were more possibly to 11 volunteer to clean up their city, visit sick children in the hospital and so on. 　　The result of experiments is that people’s helpfulness or being nice has something to do with their taste for sweet food. So eating sweet food is a useful way to make people nice and helpful. Next time, try some ice-cream. 66．What does the underlined word “it” refer to(指代) ? 　　A. The English saying.　　　　 　 B. The eating habit. 　　C. The American team.　　　 D. The sweet food. 67．According to the result of the experiments, sweet food makes people ______.　　 A. overweight　　　B. excited　　 C. friendly　 　D. relaxed 68．Which kind of people may be less helpful? A. The ones who like ice-cream.　　　　 B. The ones who prefer chocolate.　　　　 C. The ones who eat many cookies.　　　 D. The ones who eat many chips. 69．According to the passage, which of the followings is NOT true? A. Some scientists discovered something new about eating sweet food. B. Kids are told to keep away from sweet food to be fat. C. What you put in your mouth will show your character. D. If people want to be kind or friendly, they can try some sweet food. 70．What does the passage mainly talk about? 　　A. Scientists asked college students questions about their characters. 　　B. People who like sweet food are more willing to help others. 　　C. Scientists told college students not to eat sweet food. D. People’s character has nothing to do with their taste. 第 Ⅱ 卷（非选择题，共 50 分） 注意事项：  1.用钢笔或圆珠笔在第Ⅱ卷答题卡上作答，不能答在此试卷上。  2.试卷中横线及框内注有“▲”的地方，需要你在答题卡上作答。 3.答题前将答题卡密封线内的项目填写清楚。12 第一节：口语运用（共 5 小题，每小题 2 分，满分 10 分） 根据对话内容，从对话后的选项中选出能填入空白处的最佳选项，并在答题卡上将该项涂黑。 选项中有两项多余选项。 A: Hi, Mike, have you ever heard of Chinese clay art?
