D Some mammals migrate(迁徒). One of these is the caribou(驯鹿). They travel to the tundra(苔原)every summer to eat the rich grasses that grow there. When the weather becomes cooler, they migrate to the warmer forests and spend the winter there. Another mammal that migrates is the humpback whale. They spend the winter in Hawaii, and the summer in the Arctic(北极的)waters. They travel to the Arctic to eat millions of small shrimp(虾). Anther habit that some animals have to survive the cold winter is called hibernation. Animals that hibernate, rest or sleep during the winter. While they are hibernating, their bodies use up the fat layer that they have put on by eating large amounts of food during the summer. Some animals that hibernate in the Arctic are small animals called lemmings(旅鼠), squirrels(松鼠)and bears. There are two habit adaptations that animals in the Arctic have all year round. These are called herding and pack life. Caribou are example of animals that live in herds. A herd is a group of animals that lives together for most, or all of their lives. A herd of caribou can have a thousand or more animals in it. They live in herds for protection. It is easier for caribou to protect themselves when they are together than it is when they are alone. This is because the meat-eaters hunt in packs. A pack is a small group of animals that lives together. It is usually controlled by a head male and a female. All the members of the pack must obey them. Packs have a very definite social structure. Each animal in a pack has a different position, or importance. Animals in a pack are usually meat-eaters. They live together for protection and hunting purposes. 68. According to the first paragraph, the humpback whale .

E If you want to learn anything at school, you need to listen to your teachers. Unfortunately, millions of kids can’t hear what their teachers are saying. And it’s not because these students are goofing off. Often, it’s the room’s fault. Building architecture and building design can create echo(回声)-filled classrooms that make hearing difficult. Children with hearing impairments(损伤)suffer most from noisy classrooms. They sometimes can’t hear questions that other students ask in class. Compared with kids with healthy hearing, they have a harder time picking up new vocabulary words by hearing them in talking. Even kids with normal hearing have a harder time in the classroom when there’s too much noise. Younger children in particular have trouble separating important sounds – like a teacher’s voice – from background noise. Kids with learning disabilities and speech impediments(障碍)and kids for whom English is a second language also have a harder time learning in noisy situations. In recent years, scientists who study sound have been asking schools to reduce background noise, which may include loud air-conditioners and pipes. They’re also targeting outdoor noises, such as highway traffic. Noise reduction is a big deal. Why? Because quieter classrooms might make you smarter by letting you hear your lessons better. “It’s so obvious that we should have quiet rooms that allow for access to the lesson,” says Dan Ostergren, a hearing scientist. “Sometimes it surprises me that we spend so much time discussing this topic. I just want to go. Why is this hard for anyone to grasp?” 72. The underlined part “goofing off” in the first paragraph can be replaced by “ ”. A. lazyB. intelligentC. sleepyD. foolish 73. Who is most affected by noisy classrooms? A. Children with learning disabilities.B. Children with hearing impairments. C. Children with speech impediments.D. Children with normal hearing. 74. Why should noise be reduced in classrooms? A. Quiet classrooms are suitable for kids to have discussions. B. Quiet classrooms help kids recover from hearing impairments. C. Kids can become smarter after hearing lessons better. D. Kids can’t separate sounds of air-conditioners and pipes. 75. What would be the best title for the passage? A. Noisy classroomsB. Classroom design C. The sense of hearingD. Disabled kids (责任编辑：admin) |
