    题目列表(包括答案和解析)



    Saturday morning was bright and fresh. There was a song in every heart, cheer on every face, and a  spring in every step.
    Tom appeared with a bucket of white paint in one hand and a brush in the other. His Aunt Polly told him to paint the fence around the garden. It was thirty yards long and nine feet high. He felt very depressed.
    Then he had a wonderful idea. He picked up his brush and started to work.
    Soon Ben came along the road. He was happily eating an apple. He stopped to look at Tom. Tom went on painting and pretended（假装）not to see Ben.
    “I’m going swimming,” said Ben. “Do you want to go swimming, Tom? But I guess you can’t. You have to stay and work, don’t you?”
    “Work?” Tom said. “This isn’t work. I’m enjoying myself. Does a boy get a chance to paint a fence like this every day?”
    Ben  thought  about  this.  Tom  continued  painting  carefully. Sometimes he stopped, stood back to look at the fence like an artist, and then added a bit more paint in just the right place. Ben was watching Tom paint with great interest. He was getting more and more eager to have a try himself.
    After a while, Ben asked Tom if he would let him paint a little. Tom thought about it, and said,
    “No, Ben, I can’t. You see. Aunt Polly wants it to be done well. Aunt Polly said that I must paint it with great care.”
    “Oh, please, Tom,” begged Ben. “I can do it. I’ll be really careful. Just let me try. I’ll give you half of my apple. Well, I’ll give you all of it!”
    “Well, all right, Ben,” said Tom. “You must be very careful.”
    He gave Ben his brush with worry on his face but joy in his heart. He sat down under the tree, and started to eat Ben’s apple. All day, boys came to make fun of Tom, but they ended up staying to paint. When Ben got tired, Billy was waiting. He gave Tom a kite for a chance to paint. Then Johnny offered him twelve marbles, and so on.
    By late afternoon Tom had gained all sorts of toys, and the fence had gained three  coats of paint. Later Aunt Polly came to look at the painted fence. She was so pleased with Tom’s work that she gave Tom a large cake!
    【小题1】Why did Tom pretend not to see Ben when he came and watched him painting?

    A．He saw Ben eating an apple happily.
    B．He tried to make Ben interested in it.
    C．He didn’t want to go swimming with Ben at all.

    任务型阅读

    　　For a long time, scientists didn’t study animal thinking．Most of them did not believe that animals could think．They thought humans were the only thinking animals．

    　　Now more scientists are studying this subject．But it’s very hard to prove things that no one can see or measure．So some scientists decided to take a look at brains．

    　　Is bigger better?No．Cow brains are bigger than dog brains, but that doesn’t make cows smarter than dogs．And squirrels have some of the biggest brains of all for their body size．But squirrels aren’t even close to being the smartest animals in the world．So the size of a brain may give some clues(线索)about brain power, but it doesn’t prove anything．

    　　Other scientists study thinking by ________ how animals solve problems．They watch animals in the wild or do thinking tests in a lab．

    　　For example, the scientist might put some food just out of an animal’s reach．One kind of animal may grab a stick and use it to slide the food over．Another kind might not be able to figure out a way to get the food．Some scientists think animals that have lots of problems to solve must be smarter than animals with simple lives．Scientists also study certain kinds of behaviour for clues about thinking．They watch for three things：whether animals use tools, how they act with each other, and how they communicate．

    1．“This subject” in Paragraph 2 refers to ________．

    2．The underlined word “smarter” means ________ in English．(限填一词)

    3．What have scientists learned from studying the size of animals’ brains?

    ________________________________

    4．Complete the sentence with just one word：Other scientists study thinking by ________ how animals solve problems．(限填一词)

    5．Scientists study such animals’ behavior as whether animals use tools, how they act with each other and ________ as well．

    Everywhere we look, there is colour. We see it in the sky and in the sea. There are colours in all plants and animals. Colour makes our homes and schools pretty. We see it in pictures and in books. We even see colour in our food. It makes things look good.
    How can we see colour? We see colour when light hits(射入)our eyes. Dogs and many other animals can’t see colours. But bees(蜜蜂) can. They even see colours we don’t see. This helps them find flowers to fly to.
    We sometimes use the names of colours to say things. People may say that they “see red” when they are angry(生气). Or you may say you “feel blue”. This means you are sad. We use colour to tell things., too. Red is the colour of stop signs. It means to stop. Green means to go.
    Animals come in all kinds of colours. Many of these are very pretty. An animal’s colour may say “here I am”., “stay away” or “be careful” or it may help the animal hide(隐藏). Some animals can make their colours look like the trees around them, then other animals or people can not find them.
