This is the reason why this island attracts thousands of tourists around the world every year.‎ ‎【语篇解读】　本文主要介绍了位于南非的Seal Island周边的水域，大白鲨常常跳出水面猎食海豹，这一景象吸引了许多游客前去观看。‎ ‎1．What probably makes Seal Island famous?‎ A．The large number of seals in the water.‎ B．The way the great white sharks hunt.‎ C．The beautiful scenery of the island.‎ D．The special position of the island.‎ B　[细节理解题。根据第一段最后一句话可知，大白鲨跳出水面捕食海豹是Seal Island闻名于世的主要原因。]‎ ‎2．Why do the seals swim in a zigzag pattern?‎ A．To save energy.‎ B．To warm themselves.‎ C．To look for food.‎ D．To avoid the white sharks.‎ D　[推理判断题。第三段列举了海豹躲避大白鲨的方法，其中一种方法就是在水里的“之”字形游动。]‎ ‎3．We can infer from the third paragraph that ．‎ A．white sharks are dangerous animals B．the seals are cleverer than the white sharks C．the sharks are successful in hunting the seals 6‎ D．it is easier for the sharks to hunt the seals on the sea floor C　[推理判断题。根据第三段可知，几年来海豹虽然变聪明了，但它们还是难逃被大白鲨捕食的厄运，这说明大白鲨的捕食很成功。]‎ ‎4．What is the author's purpose in writing the passage?‎ A．To explain why Seal Island is famous.‎ B．To show how white sharks hunt seals.‎ C．To advise us to visit Seal Island.‎ D．To ask us to protect animals.‎ A　[写作意图题。根据第一段以及最后一段可知，这篇文章主要向我们介绍了Seal Island世界闻名的原因。]‎ Ⅱ.完形填空 Protecting China's Giant Pandas China's giant pandas show the achievement of the international effort to save animals that are now in danger.In television programs we often see pandas 1 funny games.Children have panda toys and beautiful cards with pictures of lovely 2 in them.They often visit the giant pandas in the zoos on 3 holidays and have a good time there.However，scientists are worried about the 4 of giant pandas.They know only about 1，000 giant pandas remain 5 today.They think the giant pandas will die out in 30 years if the present conditions are not 6 ．‎ It is reported that the giant pandas have a very 7 birth rate.About 115 pandas live in the zoos and research centers mainly in China，but during the past 10 years they 8 only 34 9 pandas that are still alive.The survival rate of giant pandas in the wild is probably the same or lower.‎ There are several reasons for the low 10 ．The main reason is 11 male pandas can make love with females in a very 12 season—only a few days a year.When they do have babies，females often produce two pandas，but the mother is usually not able to care for 13 of them.The newborn pandas 14 only a few kilograms each.They are too weak to live without special care.In the zoo，scientists can help the mothers 15 the young pandas，but those living in the wild do not get enough 16 ．It is very difficult for mother pandas to bring up their young pandas.‎ Conditions for the giant pandas have been worse in recent years.Pandas in China 6‎ ‎ continue to 17 in number.We know pandas live on bamboos.But sometimes all the bamboos in one area die.The pandas there have 18 to eat and die of hunger.‎ Giant pandas now live in 13 separate 19 areas in China.Several years ago the Chinese government and the International Wildlife Organization agreed 20 a project of protecting giant pandas in the wild.We hope it could be useful.‎ ‎【语篇解读】　本文主要讲述了保护大熊猫的紧迫性及相应措施。‎ ‎1．A.play　　　　　　 B．study C．do D．make A　[play games玩游戏。see sb.do sth.看见某人做某事。]‎ ‎2．A.pandas B．children C．bamboos D．zoos A　[全文都在讲述大熊猫，这里指带有可爱熊猫图案的卡片。]‎ ‎3．A.our B．their C．your D．his B　[与they保持一致应用their。]‎ ‎4．A.past B．now C．future D．present C　[根据本段的最后两句可知，科学家担心大熊猫的“将来”，担心它们会灭绝。]‎ ‎5．A.honest B．lovely C．friendly D．alive D　[remain此处用作系动词。alive活着的，在世的，存在的。]‎ ‎6．A.turned B．increased C．improved D．considered C　[他们认为如果目前这种状况不改善的话，大熊猫在三十年之内将会灭绝。improve改善，改进。]‎ ‎7．A.low B．proper C．high D．right A　[根据上文科学家担心大熊猫的将来及由birth rate出生率可知，应用low。]‎ ‎8．A.cloned B．produced C．kept D．created B　[根据语境可知应用produce生产；此处下文中的females often produce two pandas也是暗示。]‎ ‎9．A.small B．young C．little D．adult 6‎ B　[young pandas指母大熊猫生出的幼崽。]‎ ‎10．A.price B．speed C．birth rate D．limit C　[birth rate出生率，和上一段中第一句话呼应。]‎ ‎11．A.why B．how C．when D．that D　[The main reason is that...意为“主要原因是……”，that引导表语从句。]‎ ‎12．A.short B．long C．suitable D．certain A　[根据后面的only a few days a year，可知选A。]‎ ‎13．A.all B．both C．none D．neither B　[上文提到females often produce two pandas，故选both。]‎ ‎14．A.weight B．take C．weigh D．find C　[weigh为动词，意为“重；重达……”；weight为名词，意为“重量”。]‎ ‎15．A.have B．raise C．observe D．care B　[此处指科学家协助母熊猫抚养小熊猫，因此应用raise(饲养)。]‎ ‎16．A.help B．food C．water D．milk A　[此处指生活在野外的大熊猫得不到足够的帮助，呼应上文。]‎ ‎17．A.reduce B．grow C．rise D．change A　[根据上文中的．..have been worse可知，熊猫数量在减少，濒临灭绝。]‎ ‎18．A.something B．nothing C．everything D．anything B　[根据上文的all the bamboos in one area die及die of hunger可知应选nothing。]‎ ‎19．A.protected B．protecting C．defending D．guarding A　[protected areas意为“受到保护的地区”，过去分词作定语，表示动宾关系。]‎ ‎20．A.to B．with C．in D．on 6‎ D　[此处指中国政府和国际野生动植物组织在保护野生大熊猫的计划上达成共识。agree on在……上取得共识，符合语境。agree to同意某项计划或建议；agree with同意某人或某人的话；agree一般不和in连用。]‎ 6‎
