题目内容
7.Beavers are a very unique species in the world of nature and wildlife--they are architects.Their dams are fine examples of engineering.A pair of beavers will build a dam,using branches,mud and stones,across a river.The water held back by the dam flows over the bank on either side of the river,flooding the nearby ground and forming a pond.At some point in the pond the beavers then build their home,which is called a lodge.This consists of a cone-shaped(锥状的)pipe of branches and sticks of two to six feet in length held together with mud and stones,the top of which projects above the waterline.It serves as a shelter from the bad weather,a safety from enemies and a base for food supplies to be drawn upon in winter.
From an engineering point of view the lodge could hardly be improved.Not only does it contain a central room just above water level,which is accessible only through underwater tunnels,but it also has"walls",one or more escape tunnels and an air hole at the top,which controls the temperature inside and gives air-conditioning.It is altogether a clever piece of construction,with all modern conveniences.It is,in fact,better protected against the effects of flooding than many human houses.
Trees are essential to beavers.They eat the bark on the upper branches.But they must first fell the trees,using their four front teeth.With these sharp tools,it takes only a few minutes to cut down a tree.
The engineering skill of beavers is to a large extent a result of their ability to use their front paws as hands.A female will carry her young held under her chin(下巴) with her front paws,walking on her hind legs.A similar method is used by all beavers when transporting stones or mud,although they also carry such materials on their broad flat trails.The fore-paws are also used for digging and for dragging heavier pieces of wood.
32.Which of the following pictures best shows the beaver's lodge?C
A. B.
C. D.
33.Which of the following sentences is Not the reason why trees are important to beavers?B
A.They live on the barks on the upper branches of trees.
B.They use branches to transport mud and stones.
C.They build their lodge with the branches.
D.They use trees'branches to build dams.
34. The underlined word"fell"in Paragraph 4 probably meansA.
A.cut down
B.move away
C.cut up
D.move about
35. This text is mainly aboutB.
A.the beaver's lodge
B.the beaver's engineering skills
C.the beaver's dam
D.the beaver's intelligence.
分析 河狸是自然和野生动物世界里独特的物种,因为它们是优秀的建筑师,它们建造的大坝和草屋就是它们拥有工程技能的很好例子.
解答 32-35 CBAB
32题答案:C 考查细节推理,首先根据第二段的"This(the lodge) consists of a cone-shaped(锥状的)pipe of branches and sticks"(草棚是由锥形的树枝和棍子组成的管道)可知D选项排除(D是方形的),又根据后面的"It serves as a shelter from the bad weather"(草棚充当糟糕天气的遮蔽)可知A选项排除(A选项草棚有大的开口,无法防止恶劣的天气),又根据第三段的"Not only does it contain a central room just above water level"(它不仅包含一个刚好位于水平线以上的中央室)可知B选项排除(B选项活动空间在水平线以下).综上,只有C选项符合.
33题答案:B 考查细节推理,根据文章最后一段的"A similar method is used by all beavers when transporting stones or mud"(同样的方法(用前爪搬东西)被河狸用来运输石头和泥)可知B选项不是树对河狸而言重要的原因.
34题答案:A 考查细节推理,根据后面的"With these sharp tools,it takes only a few minutes to cut down a tree"(用这些尖锐的工具(牙齿),只需要几分钟就可以砍倒一棵树)可知本题答案为A选项.
35题答案:B 考查文章大意,本文主要以大坝和草屋来说明河狸具有很好的工程技术,故本题答案为B选项.

Recently,our class has had a discussion about whether Senior Three students should go on a group spring outing.
After that,Nasrudin turned to the (32)D man and shouted,"Fool!Why didn't you live with such nice feelings all the days when you were (33)D and fully alive?"With that,Nasrudin left the (34)B.The old man (35)A and said,"At last I've heard the (36)C.It is a blessing to (37)D having heard the truth."The old man died (38)D.
