Question

13．Many people think the camel stores water in its hump （駝峰），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 許多人認為駱駝的駝峰儲存水，但它沒有．駱駝的駝峰真的是一大塊脂肪．駱駝，通常被稱為"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．因為駱駝能夠把食物轉(zhuǎn)化為脂肪，然后它就把脂肪儲存在駝峰里．駱駝有單峰駝和雙峰駝兩種．有一個駝峰的駱駝被稱為阿拉伯駱駝，來自北非．雙峰駱駝主要來自亞洲．

解答 81．A．細節(jié)理解題．根據(jù)最后一段中There are one-humpcamels and two-hump camels．可知有單峰駝和雙峰駝兩種，故選A．
82．C．細節(jié)理解題．根據(jù)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．可知在一個有充足的水和食物的地方，也就是在穿越沙漠之前，駱駝吃喝得很多．故選C．
83．C．細節(jié)理解題．根據(jù)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．可知駱駝能夠把食物轉(zhuǎn)化為脂肪，然后它就把脂肪儲存在駝峰里，故選C．
84．B．細節(jié)理解題．根據(jù)A camel can go on for days or weeks with little food or water．However，when its hunger reaches the point starvation （餓死），its hump shrinks （收縮） and may even slip off its back and hang down its side，可知駱駝的駝峰從后面滑落或從側(cè)面垂下來是因為里面幾乎沒有脂肪了．故選B．
85．B．推理判斷題．根據(jù)第二段中A camel can go on for days or weeks with little food or water可知駱駝可以在艱苦的環(huán)境下生活，故選B．
