共享题干题                                                                          (一)                                                                 Teach Your Child Science根据材料,完成下列的问题。(1)It is important to make your child interested in science from an early age. Most young children ask a lot of questions and you should give careful scientific answers.Don't only give facts but try to give explanations as well.(2)Science is not just knowledge ; it is a way of thinking, a method of finding out about the world. We see something.We try to explain it, and we test our idea by setting up all experiments. One day you e home and find the plant on the table has fallen over. You think it might be the wind from the open window or the cat. So you close the window, but leave the cat in and see what happens ( you can also try leaving the window open and shunning the cat out ) . Of course, you remember there may be a third explanation.(3)Ask your child to get a piece of string, some salt, a glass of water and an ice Cube ( 冰块 ) . Tell her to put the ice in the water, and then put one end of the string on the ice, leaving the other end over the side of the glass. Put a lime salt on the ice, wait a minute, and then pull the string, it should be attached to the ice. Ask the child : "what has happened?"(4)Probably she won't know. Ask her whether fresh water or salt water freezes into ice first. If you live near the sea and have a cold winter, she should know fresh water freezes first as she will have seen that happen. Show her how to test the idea by half-filling two paper cups with water. Then put them in the icebox and checkevery three minutes. Write the results in a table. The conclusion will be that salt changes the behavior of water,thinking about the string, we see the salt turned some of the ice into water. Then the salt went away into the water and the ice froze again leaving the string attached.(5)Then you can ask, "Will water with salt boil at the same temperature as water without salt?" She can think, tell you her idea and ( taking care the heat ) you can test it in the kitchen.1.[不定向选择题]the experiment shows that salt changes the behavior of____________.A.the icebox B.the ice C.slcience answer D.the experimentE.the worldF.waterABCDEF确定 2.[不定向选择题]When your child asks you questions, you should give her____________.A.the icebox B.the ice C.science answer D.the experimentE.the worldF.waterABCDEF确定

1.参考答案:F
参考解析:根据第四段内容“The conclusion will be that salt changes the behavior of water”可知,结论是盐改变了水的状态,所以本题选F。
2.参考答案:C
参考解析:根据第一段第二句话“Most young children ask a lot of questions and you should give careful scientific artswers”可知,大部分孩子会问很多问题,你应该仔细地给出科学的答案,所以本题选C。3.[不定向选择题]We set up experiments to test our ideas about____________.A.the icebox B.the ice C.science answer D.the experimentE.the worldF.waterABCDEF确定
