2017届高考英语二轮复习考点讲义：阅读理解-科普知识与现代技术

　　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. ④Studies 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.

　　Never push a child to “Think”.It doesn’t make sense, children are always thinking, without your telling them to. What’s more ,this can turn a conversation into a performance. The child will try to find the answer you want, in as few words as possible, so that he will be a smaller target for your disagreement.

　　Lastly, show; don’t tell. Real life impressions of nature are far more impressive 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. Rather than saying that water evaporates(蒸发),set a pot of water to boil and let them watch the water level drop.
