Passage 1 Professor BumbleProfessor Bumble is not only absent-minded but short-sighted as well. /His mind is always busy with learned thoughts and he seldom notices what is going on around him./On a fine day recently he went for a walk in the countryside. /But as always he read the book as he walked. /He hadn't gone far when he ran into a large cow and fell down./ He had lost his spectacles in the fall, and he thought he had stumbled over a fat lady. /"I beg your pardon, madam," he said politely before searching for his glasses./ As soon as he had put the glasses on，he realized his mistake./Soon he was concentrating on his book again and paying no attention to anything else./ He had scarcely been walking for five minutes when he fell over again,/ losing both his book and his glasses. /This time he became very angry./ Seizing his umbrellas, he struck the "cow" in anger. /Then, after finding his glasses, he realized with horror that he had made a second mistake. /A large fat woman was running away from him in terror./Passage 2 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 work together, take turns, and encourage each other by listening, clarifying and trusting one another. /Mutual support and trust often make a great difference. /Passage 3 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 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 remember how happy I was when I saw the tray standing next the tables. It looked different from the one I was trained on. It had nice handles which made it easier to move around. I was pleased with everything and began to believe I was a 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.Passage 4 Time Has the Power to Change AttitudeLast week, my youngest son and I visited my father at his new home.My earliest memories of my father are of a tall, handsome, successful man devoted to his work and family but uncomfortable with his children. 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.

Although our times together became easier over the years, I never felt closet to him at that moment. After so many years, I’m at last seeing another side of my father.Passage 5 Experiences SpeakThere are many different ways of seeing a town for the first time. One of them is to walk around it, guidebook in hand. Of course, we may study with our guidebooks the history and special developments of a town and get to know them. But then, if we take out time and stay in a town for a while, we may get to know it better. When we look it as a whole, we begin to have some questions, which even the best guidebooks do not answer. Why is the town just like this, this shape, this plan, this size? Here even the best guide-book fails us. We can’t find in it the information about how a town has developed to the present appearance. However, we may get some idea of what it used to look like by walking around the town. A personal visit to a town may help one better understand why it is attractive than just reading about it in a guidebook.
