Children are natural scientists, very interested in the world around them. Helping them enjoy science can be easy; there’s no need for a lot of scientific terms（科学术语）or modern labs. You only have to share your children’s interests.

　 Firstly, listen to their questions. I once visited a classroom of seven-year-old children to talk about science as a job. The children asked me “textbook questions” about schooling, the money I got and whether I liked my job. When I finished answering, we sat facing each other silently. Finally I said, “Now that we’ve finished with your lists, do you have questions of your own about science?”

After a long wait, a boy put up 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 lot 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, many teachers usually wait only one second or less for an answer, no time for a child to think. When teachers increase their “wait time” to three seconds or more, children give better answers.

Thirdly, watch your language. When the child is having a science discussion, don’t jump in with “That’s right” or “Very good”. These words work well when it comes to encouraging a child to help others. But in talking about science, these words make a child think that the discussion is over. Instead, keep things going by saying, “That’s interesting” or “I’ve never thought of it that way before”, or coming up with more questions or ideas.

Lastly, show; don’t tell. Let children look at their hands through a microscope（显微镜）, and they’ll understand why you want them to wash before dinner….

A man was walking along the street when he saw a woman struggle（奋力）with a large box. It was half in and half  1  of her car. He was a helpful man, so he went up to the woman and said, “Let me give you a hand with that box. It looks very   2 . ” “That’s very kind of you,” the woman said. “I’m having a lot of  3  with it. I think it’s stuck（卡住）. ” “Together we’ll soon move it,” the man said. He  4_  into the back seat of the car and took hold of the other end of the box. He said, “I’m ready. ” And he began to_ 5  hard. For several minutes the man and the woman struggled with the box. Soon they were  6  in the face. “Let’s rest for a minute,” the man said. “I’m sorry, but it  7  stuck. ” A few minutes later, the man said, “Let’s try again. Are you ready?”  8  of them took hold of the box again. “One, two, three!” the man said, and they went on with their struggle.
At last, when they were very tired, the man said, “You are  9 . It really is stuck. I don’t think there’s any way we can get it out of the car. ” “Get it out of the car!” The woman cried. “I’m trying to get it  10 !”
