问题    Children start out as natural scientists, instinctively eager to investigate the world around them. Helping them enjoy science can be easy—there is 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 career. 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’ve finished your lists, do you have questions of your own about science?
   After a long period of pause, a boy raised his hand, "Have you ever seen a grasshopper eat? When I try eating leaves like that, I get a stomachache. Why?"
   This caused a series of questions and discussions that lasted nearly two hours.
   Secondly, give them time to think. Studies over the past three decades have shown that, after asking a question, adults typically wait only one second or less for a response, no time for a child to think. When adults increase their "wait time" to three seconds or more, children respond with more logical, complete and creative answers.
    Thirdly, watch your language. Once you have a child engaged 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 urge a child to think. It doesn’t make sense, as 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 he will be a smaller target for your  disapproval.
    Lastly, show, don’t tell. Real-life impressions of nature are far more impressive than any lesson children can extract from a book or a television program. Let them look at their fingertips through a magnifying glass, and they’ll understand why you want them to wash before dinner. Rather than saying that water evaporates, set a pot of water to boil and let them watch the water level drop. Thus, children will get a better comprehension of what they have observed.
According to the passage, children tend to give more logical, complete and creative answers if adults ________.

选项 A、encourage them to ask questions of their own
B、urge them to think and give immediate answers
C、give them more than three seconds to think after a question
D、give them time to have a fierce discussion

答案C

解析 此题来源于第四段:When adults increase their“wait time” to three seconds or more...(当成人把等待时间延长到三秒以上……)。A与题意无关。D选项文中没有提及,B选项作者在第六段给予反驳——Never urge a child to think.(不要催促孩子去想。)
