Scientists call this "magnetoreception".Pigeons are famous for this ability.They can fly hundreds of kilometres and still return home. But pigeons are not the only animals with this skill.Sea turtles also use the Earth's magnetic field to navigate().After hatching on beaches,baby sea turtles swim into the ocean.They "remember"the magnetic field of the beach and return to the same place many years later to lay eggs. Bees also have magnetoreception.They use it to find flowers and return to their hives ()In experiments,scientists changed the magnetic field around a beehive.The bees flew in the wrong direction (and had trouble finding their way back. How do animals sense the magnetic field?Scientists believe that some animals have tiny magnetic particles(磁性颗粒)in their bodies.These particles move when the magnetic field changes,sending signals to the brain.This helps the animals "feel" direction. This special sense is still not fully understood.But it shows how wonderful nature is. ()1.What does the underlined word "magnetoreception"mean? A.The ability to see colours. B.The ability to sense heat. C.The ability to feel direction through magnetic fields. D.The ability to communicate with other animals. ()2.According to the passage,which animal use magnetoreception to return to the same beach to lay eggs? A.Pigeons. B.Sea turtles. C.Bees. D.Both pigeons and bees. ()3.What happened when scientists changed the magnetic field near a beehive? A.The bees made more honey. B.The bees started fighting. C.The bees got lost easily. D.The bees flew faster. ()4.How do animals sense the magnetic field according to scientists? A.By using their eyes. B.By listening to sound. C.By moving tiny particles in their bodies. D.By following other animals. ()5.Which of the following is TRUE according to the passage? A.Only pigeons have the ability of magnetoreception. B.Scientists know exactly how magnetoreception works. C.Baby sea turtles learn the magnetic field of their home beach. D.Bees use magnetoreception only to find flowers. B篇 Many people think that pigeons are common and uninteresting birds.But a student named Jack had a different experience.In his biology class,the teacher asked everyone to choose an animal to study.Jack chose pigeons,though he thought they were boring at first. In the first few days,Jack went to the park to watch pigeons.They seemed to do nothing but walk around and eat food.He wrote in his diary,"Pigeons are so boring! They just knock around all day and leave droppings everywhere."He felt disappointed (失望的)， But then things changed.His teacher suggested he search online for more information.Jack started reading articles about pigeon intelligence()He found out that pigeons can recognise themselves in mirrors一a sign of self-awareness(自我意 )They can also remember hundreds of different pictures.Some pigeons can even tell the difference between paintings by different artists! Jack became very interested.He decided to do a small experiment.He put a mirror in his garden and watched a pigeon.To his surprise,the pigeon looked at itself and started to clean its feathers in front of the mirror.Jack recorded the moment and shared it with his classmates. "At first,I thought pigeons were dirty and stupid.But now I realise they are amazing animals.We only need to take time to understand them,"Jack wrote in his final report. ()1.How did Jack feel about pigeons at the beginning of his study? A.He found them interesting. B.He thought they were boring and dirty. C.He was afraid of them. D.He thought they were very smart. ()2.What changed Jack's opinion about pigeons? A.Watching them in the park. B.Reading online information. C.Talking to his teacher. D.Seeing them in the mirror. ()3.What did Jack's experiment prove? A.Pigeons can talk to each other. B.Pigeons can recognise themselves. C.Pigeons are afraid of mirrors. D.Pigeons can paint pictures. ()4.What lesson did Jack learn from the experience? A.All animals are the same. B.Online research is not helpful. C.We shouldn't judge animals too quickly D.Pigeons are the smartest animals ()5.Which of the following is the best title for the passage? A.A Smart Student B.The Magic Mirror C.My Unforgettable Experiment D.A Surprising Discovery about Pigeons 二、完形填空 A boy named Tom was doing a school project on animals.He chose to 1. about bees.At first,he thought bees were simple insects.But soon he 2. they were amazing Tom found out that bees have a special "language".When a worker bee finds a good flower,it flies back to the hive and does a dance.The dance tells other bees the 3. and distance(距离)to the flower.Different moves(动作)mean different information.Tom was 4. that such small insects could communicate in this way. He also learned that bees play a very important role in nature.They help plants grow by 5.pollen()from one flower to another.Without bees,many fruits and vegetables would not grow.However,the number of bees is 6.fast because of pesticides(杀虫剂)and habitat loss. Tom wanted to do something to help.He decided to plant some flowers in his garden 7. bees could find food.He also told his neighbours about the importance of bees.Some of them agreed to plant flowers 8. One day,Tom saw a bee that seemed to be tired and weak.He put a small dish of sugar water near it.To his joy,the bee drank the water and flew away after a few 9. Tom's project not only taught him a lot,but also inspired him to protect these little 10. He gave a talk in class and said,"Bees are small,but they are powerful.We should do our best to protect them."

Another interesting fact is that some pigeons can tell the difference between different kinds of art.In one study,pigeons were shown paintings by Monet and Picasso.After some training,they could tell which painting was by which artist.Even more surprising, they could recognise new paintings by the same artists.This shows that pigeons can learn to group(份类)things by style.. Pigeons also have an excellent memory ()They can remember hundreds of different pictures for a long time.In an experiment,pigeons were shown pictures of simple objects.Two years later,they could still remember many of them.This is better than many people's memory for such things. These studies show that pigeons are much smarter than most people think.Next time you see a pigeon,take a closer look.Maybe it's thinking about something more than just a piece of bread. 1.According to the passage,which animals besides pigeons can recognise themselves in mirrors? 2.What did the study about artists show about pigeons? 3.How long could pigeons remember pictures in the experiment? 4.Is a pigeon's memory for simple pictures better or worse than a human's? 5.What does the writer suggest we do when we see a pigeon? 四、短文填空 用方框中所给单词的适当形式填空，使短文完整正确。（每个单词限用一次，每空限填一个单 词。) know,different,interest,research,recognise,they,fly,surprise,although,other Are you afraid of spiders?Many people are,1._ spiders are actually very helpful to nature.They eat many small insects.But how much do you 2.about these amazing animals? Scientists have done a lot of 3. _on spiders.Some spiders can jump 40 times the length of their body.Others can "fly"by using threads()of silk.They let the wind carry 4.to new places. One 5.thing about spiders is that they have eight eyes.However,most of them don't see very well.Instead,they use tiny hairs on their legs to feel the world around them.They can even 6.different kinds of vibrations through the air. There are over 50,000 7.kinds of spiders in the world.Some are very small,and some are big enough to eat birds.You might be 8.to learn that the largest spider in the world is the Goliath birdeater.It can grow up to 30 centimetres long! 9. some spiders look scary,they are an important part of our environment.The next time you see a spider,don't be afraid.Try to watch it closely.You might find it very 10. 1. 2. 3 4. 5. 6. 2 8. 9. 10. 五、写作 话题：My Understanding of Animals 提示： 1.你曾经对什么动物有过误解？ 2你是如何改变这种看法的？ 3.这次经历对你的启示是什么？ 要求：80词左右，语句通顺，语法正确。可以结合本单元关于鸽子的故事来写。 参考答案 一、阅读理 A篇：1.C2.B3.C4.C5.C 解 B篇：1.B2.B3.B4.C5.D 二、完形填 空 1.B;2.A;3.C;4.D;5.A;6.B;7.C;8.B;9.C;10.D 1.Dolphins,,elephants,.and great apes..(写全三或写"Dolphins,elephants and great apes" 三、阅读短 2.learn to group tell the difference)things by style. 文回答问题 3.Two years. 4.Better than a human's.(或比人类的好) 5.Take a closer look. 四、短文填 1.although 2.know 3.research 4.them 5.interesting 6.recognise 7. 空 different 8.surprised 9.Although 10.interesting 五、写作 范文： My Understanding of Animals I used to think pigeons were boring and dirty.When I saw them in the park,they just walked around and left droppings everywhere.I never wanted to get close to them. But after reading a story about pigeons,my idea changed.I learned that pigeons can recognise themselves in mirrors and fly very fast.They are actually smart animals.Now I think we should not judge animals too quickly.Everyone,including animals,has amazing sides if we take time to understand them.
