第1篇TeamworkTeamwork is just as important in science as it is on the playing field or in the gym. Scientific investigations are almost always carried out by teams of people working together. Ideas are shared, experiments are designed,data are analyzed, and results are evaluated and shared with other investigators. Group work is necessary, and is usually more productive than working alone.Several times throughout the year you may be asked to work with one or more of your classmates. Whatever the task your group is assigned, a few rules need to be followed to ensure a productive and successful experience.What comes first is to keep an open mind, because everyone's ideas deserve consideration and each group member can make his or her own contribution. Secondly, it makes a job easier to divide the group task among all group members. Thirdly, always worktogether, take turns, and encourage each other by listening, clarifying, and trusting one another. Mutual support and trust often make a great difference.Useful words and expressions:playing field n. 运动场productive adj. 多产的，有生产价值的productive force 生产力productive labor 有价值的劳动a productive farm 肥沃的农场a productive writer 多产作家investigation n. 调查，研究(be) under investigation 在调查研究中bear investigation 经得起考查，不怕追查keep an open mind 不抱成见，抱着虚心态度make a great difference 有很大差别，有很大影响听力源文件下载地址：/s/1i3iV5Tb第2篇Mistakes Are Good TeachersAfter the birth of my second child，I got a job at a restaurant. Having worked with an experienced waitress for a few days，I was allowed to wait on tables on my own. When Saturday night came，I was luckily given the tables not far from the kitchen.However，I still felt a little hard to carry the heavy trays. So I moved slowly, minding every step. I remembered how happy I was when I saw a tray standing next to the tables. It looked different from the one I was trained on，and it had nice handles which made it easier to move around. I was pleased with everything and began to believe I was natural at this job. Then, an old man came to me and said that was his wife's walker. I stood frozen as ice，but my face was on fire. Since then, I have learned to be more careful and not to be too sure of myself.

As a child, I loved him；as a school girl and young adult, I feared him and felt bitter about him.On the first day of my visit, we did some shopping，ate on the street table，and laughed over my son's funny facial expressions. Gone was my father's critical air and strict rules. Who was this person I knew as my father who seemed so friendly and interesting to be around?The next day, my dad pulled out his childhood pictures and told me quite a few stories about his own childhood. Although our times together became easier over the years, I never felt closer to him until that moment. After so many years, I'm at last seeing another side of my father.Useful Words and Expressions:devote [di'vaut] 投人于，献身be devoted to 专心于devote oneself to sth.献身于，致力于He's devoted to me.他对我忠心耿耿。

Some people are compulsive shoppers. Others find it impossible to pull themselves away from their work. Still others spend countless hours watching TV or playing computer games.Over the years, shopping has become a very common activity. Many people enjoy going to malls or stores more and more every day, but it's more than a common hobby for some of them. They have turned into shopaholics. They are people who simply enjoy shopping and walking around spending money without being able to stop doing it. They are hooked on shopping and usually buy things that they don't need. Even though they don't have enough money, they want to buy everything they want.Why do they have this addiction? There isn't a specific answer. Some people go shopping when they are sad, worried, upset or lonely. Some even tend to have this addiction when they feel guilty.Useful Words and Expressions:addiction n. 入迷，上瘾had an addiction for fast cars 有开快车的嗜好shopaholic n. 购物狂compulsive adj. 强制的，强迫性的What is your most compulsive habit? 你最强迫性的习惯是什么？Compulsive eating is bad for one's health. 无节制的大吃大喝有损身体健康。
