Question

13．Many people think the camel stores water in its hump （驼峰），but it does not．Instead，the camel stores something else there-food．The came's hump is really a hump of fat （ 脂肪）．The camel is often called"a ship of the desert"．When the camel is not travelling and is in a place where there is much food and water，it eats and drinks a lot．As it does so，its hump rises from the fat its body makes．Then，when the camel is travelling through the desert and when there is no food，it can live off the stored fat．

Answer 1

分析 许多人认为骆驼的驼峰储存水，但它没有．骆驼的驼峰真的是一大块脂肪．骆驼，通常被称为"沙漠之舟"，在有充足的水和食物的地方，它吃很多食物，喝很多水．因为骆驼能够把食物转化为脂肪，然后它就把脂肪储存在驼峰里．骆驼有单峰驼和双峰驼两种．有一个驼峰的骆驼被称为阿拉伯骆驼，来自北非．双峰骆驼主要来自亚洲．

解答 81．A．细节理解题．根据最后一段中There are one-humpcamels and two-hump camels．可知有单峰驼和双峰驼两种，故选A．
82．C．细节理解题．根据第一段中When the camel，often called"a ship of the desert"，is not travelling and is in a place where there is plenty of food and water，it eats and drinks a lot．可知在一个有充足的水和食物的地方，也就是在穿越沙漠之前，骆驼吃喝得很多．故选C．
83．C．细节理解题．根据第一段中As it does so，its hump rises from the fat its body makes．Then when the camel is travelling through the desert and when there is little food，it can live off the stored fat．可知骆驼能够把食物转化为脂肪，然后它就把脂肪储存在驼峰里，故选C．
84．B．细节理解题．根据A camel can go on for days or weeks with little food or water．However，when its hunger reaches the point starvation （饿死），its hump shrinks （收缩） and may even slip off its back and hang down its side，可知骆驼的驼峰从后面滑落或从侧面垂下来是因为里面几乎没有脂肪了．故选B．
85．B．推理判断题．根据第二段中A camel can go on for days or weeks with little food or water可知骆驼可以在艰苦的环境下生活，故选B．
