Farmers used to hunt them without mercy. Now they allowed tourists to hunt only a certain number of animals if they paid the farmers. The problem was solved.In the thick rainforest, a monkey was rubbing a millipede insect which contains a powerful drug to protect (protect)him from mosquitoes.

Unit 4 Wildlife Protection Language points课时作业[高考题型练习提能力]Ⅰ.阅读理解AOctopuses (章鱼) are sea animals famous for their roundedbodies，bulging eyes，and eight long arms.They live in all theworld's oceans but there are especially more octopuses in warm，tropical (热带的) waters.Octopuses，like their cousin，the squid(乌贼)，are often considered “monsters of the deep”，though some species，or types，occupy relatively shallow waters.Most octopuses stay along the ocean's floor，although some species are pelagic，which means they live near the water's surface.Other octopus species live in deep，dark waters，rising from below at dawn and dusk to search for food.Crabs and shrimps rank among their favorite foods，though some can attack larger prey (猎物)，like sharks.Octopuses typically drop down on their prey from above and，using powerful suctions that line their arms，pull the animals into their mouths.The octopus performs its famous backward swim by blowing up water through a muscular tube on the body called a siphon.Octopuses also crawl along the ocean's floor，putting their arms into small openings to search for food.Seals，whales，and large fish prey on octopuses.If threatened，octopuses shoot an inky liquid that darkens the water，confusing the other animals.The octopus can also change to gray，brown，pink，blue，or green to mix with its surroundings.Octopuses may also change color as a way to communicate with other octopuses.Octopuses are solitary creatures that live alone in dens (巢穴) built from rocks，which the octopus moves into place using its powerful arms.Octopuses sometimes even fashion a rock “door”for their dens that pull closed when the octopus is safely inside.【语篇解读】本文主要介绍的是章鱼的生活习性。
1．In which place can we find more octopuses?A．The ocean near Hainan.B．The river near Canada.C．The Arctic Ocean.D．The South Pole.A[细节理解题。
根据第一段中的“but there are especially more octopuses in warm，tropical waters.”可知，在海南附近的海洋中能找到更多的章鱼。
] 2．What is a way for octopuses to communicate with each other?A．Using special signals.B．Making special sounds.C．Living together in a group.D．Changing their own colors.D[细节理解题。
根据最后一段中的“Octopuses may also change color as a way to communicate with other octopuses.”可知，章鱼通过改变颜色的方式与其他章鱼进行交流。
]3．What do we know about octopuses?A．They just stay in deep ocean.B．They eat food by using their teeth.C．They don't like hunting large animals.D．They shoot an inky liquid to avoid dangers.D[细节理解题。
根据最后一段第一句话可知，它们喷射出墨汁似的物质迷惑敌人，以避开危险。
]BIn the Arctic Ocean waters live the social animals—belugas，which is also known as white whales.Highlyintelligent，these whales use different sounds to communicateand find their way.Belugas are also among the smallest kindsof whales.More than 210 belugas，including 31 in the United States，live in aquariums (水族馆) around the world.The Georgia Aquarium has asked for permission to bring 18 more belugas into the US.The whales were caught off the coast of Russia.The National Oceanic and Atmospheric Administration (NOAA) is considering the aquarium's request thoroughly.A law called the Marine Mammal Protection Act (MMPA) says the animalscan only be brought into the country and put on display if they are caught without being hurt and there is an educational reason for doing so.Georgia Aquarium officials say the 18 belugas will help people learn more about the species and allow scientists to better understand how to protect it.The aquarium would also breed the whales so the US aquariums can continue to display them.“When we can study and observe，we gain a better understanding of their biology and diseases that affect them，and learn how to aid populations in their natural habitats，”says William Hurley，Georgia Aquarium's chief officer.“Much of this research would be impossi ble in the remote locations and extreme climates where the animals live.” The Georgia Aquarium would own the 18 belugas and would rent some to aquariums across the country.Meanwhile，many scientists，including Lori Marino，a whale expert，feel strongly that the whales belong in the ocean，not in tanks.These scientists say the whales are being used for entertainment and not for education，and having them in aquariums is not necessary for the species to survive.Marino said，“Not only is it unfair to the belugas but there is no educational value in putting these whales on display.”【语篇解读】白鲸是一种生活在北极的聪明的动物，现在有210多头生活在人类世界的水族馆里，美国的一家水族馆请求再引进18头，引起了专家们的争论。
4．What can we learn about belugas?A．They live in the Atlantic Ocean.B．They are highly thought of.C．They are very smart whales.D．They are the smallest in number.C[细节理解题。
