And Tom was no different One summer day Tom told Huck about his idea. “Where can we look for treasure?” asked Huck.“It’s hidden on islands, under dead trees, but mostly under the floors in haunted(闹鬼的) houses.”So, one Saturday afternoon Tom and his friend went to look for treasure as the haunted house on Cardiff Hill. It was a quiet and lonely which made the boys feel very frightened. They entered quietly, and explored downstairs. There were cobwebs everywhere and everything was old and broken. Then they threw their tools in a corner and walked upstairs, but there was nothing there. They were just about to go downstairs and start digging when Tom stopped.“What is it?” whispered Huck, going white with fright.“Keep quiet! There’s someone downstairs.”The boys lay down, looking through the holes in the wooden floor. There were two men downstairs. One was an old Spaniard in a wide sombrero hat and the other was duty and unpleasant-looking.Tom and Hack shook with fear when they heard the Spaniard speak because they found it was Indian Joe He said. “It’s time for us to move, partner. What will we do with the $650 form the robbery(抢劫)?”“Let’s keep $30 each and leave the bag here.”The dirty man went to the fireplace and moved a stone. Then he lifted out a bag full of money and look out some coins.The two boys forgot all their fears when they saw there was real treasure downstairs.Then Indian Joe started digging a hole with his knife and the knife hit something.“What is it?” asked the other man.“It’s a box,” said Indian Joe. And he put in his hand and pulled out a handful of gold coins. The other man found the boys’ tools, and they soon pulled out the box.“Where’s thousands of dollars in there,” Said Indian Joe.“The Murrell Gang used this area one summer,” said his partner.“They most have hidden their money here.”“What will we do with this, Joe? Will we bury(埋)it again?”“No, someone might find it,” said Indian Joe. “Let’s bury it in the member two den.”Tom and Huck got up as soon as the two men left.

But they’re not real stars. They’re man-made satellites(人造卫星). And the biggest of all is the International Space Station (ISS). From May to July is the best season to watch the ISS flying over the earth. And people can see it with their eyes.The ISS is the biggest satellite and scientists want to live on it. They think that the best way to learn more about space is to live there.When the space station is finished, it will be like a city in space. People will stay and study there with many of the things they have at home. Laboratories, living rooms and power stations are being built. The ISS is the most expensive space program. Billions of dollars are being spent on it every year.Scientists hope that the ISS will be a stepping stone for future space exploration(探测). “The ISS will help us understand the human body better, explore space and study the earth. It can help us make life on the earth better,” said Kathryn Clark, an ISS scientist.Sixteen countries are part of the program: the US, Russia, Canada, Japan, Brazil and 11 European countries. China isn’t an ISS country, but it has helped with some of the experiments. In 2003, China sent some rice up to the ISS to find out what space would do to it.根据短文内容，选择正确答案。

They said they would move here and planned to send their deaf daughter to my school as a first grader. They were upset that their child’s kindergarten(幼儿园) teacher told them not to have high hopes for her. Standing behind them was Katherine，a beautiful five-year-old with long hair and dark eyes. The whole time her parents were there，she didn’t make a sound or use sign language，even when her parents asked her to do so.After a few weeks with Katherine，I discovered she was a very smart child. Although she joined in different learning activities，writing was always a problem . I tried all kinds of ways to get her interested in writing，but she always refused to write.One day Katherine got off the school bus and stood in front of the school crying. The teachers there did not know enough sign language to ask her what happened. Finally they led her into the office and gave her a pen and a piece of paper. Katherine wrote：“PACBAK”. Then the teachers realized she had left her backpack on the bus. They called the bus driver back to school and soon Katherine got her backpack back.That day_____________________From then on she fell in love with writing.

It was not a valuable book, and so a poor man bought it for a few copper coins (铜钱). Between its pages there was something very interesting. It was a thin paper on which was written the secret of the touchstone!The touchstone was a small pebble (卵石) that could turn any common metal into gold. The writing explained that it was among thousands of other pebbles that looked exactly like it. But the secret was this: the real stone would feel warm, while ordinary pebbles were cold.So the man camped on the seashore and began testing pebbles. He thought that if he picked up ordinary pebbles and put them down again, he might pick up the same pebble hundreds of times. So, when he felt one that was cold, he threw it into the sea.He spent a whole day doing this but none of them was the touchstone.The days became weeks and the weeks into months. One day, however, he picked up a pebble and it was warm. He threw it into the sea before he realized what he had done. He had formed such a strong habit of throwing each pebble into the sea. So when the one he wanted came along, he still threw it away.So it is with opportunity. Unless we are careful, it’s easy to fail to recognize an opportunity when it is at hand. And it’s just as easy to throw it away.1．The poor man bought the book because ______.A．it was very cheap B．it was of great valueC．there was a secret in the book D．he wanted to find the touchstone2．According to the story, the touchstone______.A．is a big pebble B．feels coldC．is magic D．is pure gold3．The man threw pebbles into the sea _____.A．to test how far he could throw B．to practice throwing pebblesC．to avoid picking up the same pebble D．to express his disappointment4．What message does the story want to tell us?A．Careful habits can lead to success. B．Habits can benefit you but also hold you back.C．Never judge a person or a thing by appearance. D．Opportunity only visits the ready and watchful mind.D16、阅读理解（20小题，每小题2分，共40分）Not long ago, I asked large mid-aged persons a question. I asked, “How many of you had a hobby when you were children?” Nearly everyone r aised a hand. I then asked them to keep their hands in the air if they knew at least one of their children had a hobby. Most of the hands went down. I felt sad. It’s terrible if the children don’t have a hobby. How I wish all the parents can care their chi ldren’s hobbies!Thirty years ago, almost every child in my neighborhood had some kinds of hobbies. Collecting and trading baseball cards was a popular hobby. Others, like coin collecting and stamp collecting, are also popular. One of my friends was collecting photos, another was collecting radios. In fact, hobbies can benefit children in several ways.Theyare expressions of personal success and self-discovery(自我发现). Hobbies also help build self- respect(自尊). Hobbies are educational tools, as well. For example, a child who becomes interested in rocketry (火箭技术) —one of the most popular hobbies, can explore those skills in many ways. By working on hobbies, children learn to set goals, make decisions, and solve all sorts of problems.根据材料内容选择最佳答案，并将其标号填入题前括号内。
