They build their homes about 4.6 m above the river, an important feature (特征) for the safety of the young. It is called the hoatzin.In appearance, the birds of both sexes look very much alike with brown on the back and cream and red on the underside. The head is small, with a large set of feathers on the top, bright red eyes, and blue skin. Its nearest relatives are the common birds, cuckoos. Its most striking feature, though, is only found in the young.Baby hoatzins have a claw on the leading edge of each wing and another at the end of each wing tip. Using these four claws, together with the beak(喙), they can climb about in the bushes, looking very much like primitive birds must have done. When the young hoatzins have learned to fly, they lose their claws.During the drier months between December and March hoatzins fly about the forest in groups of 20 to 30 birds, but in April, when the rainy season begins, they collect together in smaller living units of two to seven birds for producing purposes.When danger comes in the form of a snake or a monkey, the young hoatzins maybe three in one family jump over the side and into the river. They swim about under the water until it is safe to return and then, using their claws, lift themselves up through the branches and get back home. When they have learned to fly they lose their claws and escape enemies not by swimming but by flying off, in a slow and heavy way, to a neighboring tree.语篇解读：生活在亚马孙丛林中的麝雉在学会飞之前就会游泳了。它头上长有美丽的羽冠，喙很硬。麝雉栖息于河边的森林中，擅长游泳，常常在水面上方的树枝上筑巢。雏鸟翅膀上长有爪子(长大后爪子消失)，能用爪子和喙攀登树木，与成鸟一样也会游泳。1What is the text mainly about?AHoatzins in dry and rainy seasons.BThe relatives and enemies of hoatzins.CPrimitive birds and hoatzins of the Amazon.DThe appearance and living habits of hoatzins.解析：选D主旨大意题。全文介绍了麝雉的外形和生活习性，故答案为D。2Young hoatzins are different from their parents in that _.Athey look like young cuckoosBthey have claws on the wingsCthey eat a lot like a cowDthey live on river banks解析：选B推理判断题。根据第一段中的“has claws(爪) on its wings when young”和第三段中的“When the young hoatzins have learned to fly, they lose their claws”可知，麝雉幼鸟与成鸟不同的是幼鸟翅膀上长有爪子。答案为B。3What can we infer about primitive birds from the text?AThey had claws to help them climb.BThey could fly long distances.CThey had four wings like hoatzins.DThey had a head with long feathers on the top.解析：选A推理判断题。根据第三段中的“Using these four claws, together with the beak(喙), they can climb about in the bushes, looking very much like primitive birds must have done”可知，原始的鸟可能使用爪子攀爬。答案为A。4Why do hoatzins collect together in smaller groups when the rainy season comes?ATo find more food.BTo protect themselves better.CTo keep themselves warm.DTo produce their young.解析：选D细节理解题。根据最后一段中的“but in April, when the rainy season begins, they collect together in smaller living units of two to seven birds for producing purposes”可知，它们在雨季聚在一起是为了繁殖后代。答案为D。BAndy rode slowly on his way to school, daydreaming about the fishing trip that his father had promised him. He was so busy dreaming about all the fish he would catch that he was unaware of everything else around him.He rode along until a strange sound drew him to the present. He came to a stop and looked curiously up to the heavens. What he saw shocked and terrified him. A huge swarm of bees filled the sky like a black cloud and the buzzing mass seemed to be heading angrily towards him.With no time to waste, Andy sped off in the opposite direction, riding furiously but without knowing how to escape the swarm.With a rapidly beating heart and his legs pumping furiously, he sped down the rough road. As the bees came closer, his panic increased. Andy knew that he was sensitive to bee stings (蜇). The last sting had landed him in hospital and that was only one bee sting! He had been forced to stay in bed for two whole days. Suddenly, his fathers words came to him. “When you are in a tight situation, dont panic. Use your brain and think your way out of it.”On a nearby hill, he could see smoke waving slowly skywards from the chimney of the Nelson family home. “Bees dont like smoke，” he thought. “They couldnt get into the house.” Andy raced towards the Nelson house, but the bees were gaining ground. Andy knew he could not reach the house in time. He estimated that the bees would catch up with him soon.Suddenly, out of the corner of his eyes, he spotted a small dam used by Mr. Nelson to irrigate his vegetable garden. Off his bike and into the cool water he dived, disappearing below the surface and away from the savage insects. After holding his breath for as long as he could, Andy came up for air and not
