Section D Directions: Read the following text about children’s curiosity. For questions 41-45, choose the answer (A, B, C or D) which you think fits best according to the text. Share Children’s Curiosity Children start out as natural scientists, eager to look into the world around them. Helping them enjoy science can be easy; there’s no need for a lot of scientific terms or expensive lab equipment. You only have to share your children’s curiosity. Firstly, listen to their questions. I once visited a classroom of seven-year-olds to talk about science as a job. The children asked me “textbook questions” about schooling, salary and whether I liked my job. When I finished answering, we sat facing one another in silence. Finally I said, “Now that we’re finished with your lists, do you have questions of your own about science?” After a long pause, a boy raised his hand, “Have you ever seen a grasshopper (蚱蜢) eat? When I try eating leaves like that, I get a stomachache. Why?” This began a set of questions that lasted nearly two hours. Secondly, give them time to think. Studies over the past 30 years have shown that, after asking a question, adults typically wait only one second or less for an answer, no time for a child to think. When adults increase their “wait time” to three seconds or more, children give more logical, complete and creative answers. Thirdly, watch your language. Once you have a child involved in a science discussion, don’t jump in with “That’s right” or “Very good”. These words work well when it comes to encouraging good behavior. But in talking about science, quick praise can signal that discussion is over. Instead, keep things going by saying “That’s interesting” or “I’d never thought of it that way before”, or coming up with more questions or ideas. Lastly, show; don’t tell. Real-life impressions of nature are far more imposing than any lesson children can learn from a book or a television program. Let children look at their fingertips through a magnifying glass(放大镜), and they’ll understand why you want them to wash before dinner. 41.
