Our teacher told us that we would see many interesting things there, but I did not know whether it would be so exciting. 　　The first room was about the earth. A guide asked us if we knew how old the earth was. Nobody could answer, so she told us that it is about 4.6 billion years old. Then she showed us a big model of the solar system （太阳系） and explained why the planets move around the sun. 　　In the next room, we saw a piece of amber. The guide said that amber is a window on the past. She told us that scientists had found a dinosaur tail with feathers in amber from Southeast Asia. "Can you believe that dinosaurs had feathers?" she asked. We were all surprised, and I began to wonder if there were other secrets waiting for us to discover. 　　Before we left, the guide told us something that I will never forget: "Science begins with questions. If you keep asking why, how and what, you will unlock more secrets of nature." 任务一：单项选择 1. How did the writer feel before the visit? A. Not sure whether it would be exciting.　B.

Today, scientists believe that there may be many other planets like ours in space. 　　In 2006, scientists agreed that Pluto was not a true planet. Since then, they have kept looking for new worlds. With powerful telescopes, they have found thousands of planets outside our solar system. Some of them are rocky, and some may even have water. Water is important because most living things need it. 　　However, nobody knows yet whether there is life on these planets. They are very far away, and even the fastest spaceship would take thousands of years to reach them. Scientists say that we may find the answer in the future, but it will not be easy. 　　"We are asking one of the oldest questions of all," says one scientist. "Are we alone? We don't know the answer yet, but we will keep looking. That is what science is about." 任务一：单项选择 1. Why did scientists stop calling Pluto a true planet? A. It was too far away.　B. They agreed it was not one. C. It moved too fast in space.　D. It had no water at all. 2. Why is water important for a planet? A. It makes the planet look bright.　B. It helps the planet move faster. C. It stops the planet from getting cold.　D. Most living things need it. 任务二：判断正误（T/F） 3. Scientists have found thousands of planets outside our solar system. （　　） 4. Scientists already know that there is life on other planets. （　　） 任务三：简答 5. Why is it hard to reach those planets? _______________________________________________________________________________ 任务四：单元微写作 　　以“What I know about nature”为题写一段短文，用 that / if / whether 引导的宾语从句写 4—5 句：介绍你了解到的一个自然事实（例如恐龙是否有羽毛、琥珀能告诉我们什么、地球上的生命如何变化），并说说你的感受。不少于8句话，请使用 know that、wonder if、tell us whether、unlock the secrets of、a window on the past 等表达。 _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ 参考答案 夯实基础 一、单词汉译英　1. newspaper　2. writing　3. style　4. method　5. text　6. alive　7. argument　8. board　9. planet　10. whether　11. fully　12. belief 二、短语汉译英　1. find out　2. unlock the secrets of sth.　3. thanks to　4. bring sth. alive　5. message board　6. used to do sth.　7. no longer　8. natural wonder 三、词形变换　1. fully　2. northern　3. unlock　4. argument　5.

I know that the earth is about 4.6 billion years old. I also know that dinosaurs had feathers, because scientists found a dinosaur tail with feathers in amber. I wonder if there are still unknown species in the world, and I hope scientists will unlock the secrets of nature one day. I am not sure whether life exists on other planets, but I think it is possible. A piece of amber is like a window on the past, and it can tell us whether life on earth has changed. I find all these facts amazing, and they make me want to learn more about nature. 学科网（北京）股份有限公司 $
