题目内容
2.根据短文内容,从短文后的选项中选出能填入空白处的最佳选项.选项中有两项为多余选项.Many of us feel sleepy in winter,but other species often take it a step further and hibernate (冬眠).(36)BThe body slows down and breathing,temperature and metabolic and heart rate all decrease.Dormice (睡鼠) head underground and hedgehogs (刺猬) hunker down in their nests.
Hibernation seems to do them good.But human cannot bed down for long periods.(37)E To work out why we do not,first we need to find out why animals do.The most obvious reason for hibernating is to avoid the cold.Conditions are harsh and there is little food to eat,as fewer plants are growing.(38)G Then they live off body-fat reserves until it's time to wake up.
But a 2015study of dormice found that they continued hibernating even when cold conditions had ended. (39)AThe key issue seemed to be connected with their main food:beech trees.The dormice need their seeds to reproduce,or for the baby dormice to gain enough body fat.In a harvest year,they produce plenty of seeds.Somehow the dormice could predict it.Otherwise,they stop reproduction these years and increase their survival by staying underground.
(40)FBy staying out of sight,the dormice avoided being hunted by their predators (天敌) like owls.Until recently people thought hibernation was just about energy saving,a defense against cold weather and food shortage,and now we think it's more predator avoidance.The survival rates in hibernation are close to 100%.
A.So obviously there are other reasons.
B.They were hibernating underground to save energy.
C.Hibernation is an extended period of energy-saving state.
D.All kinds of animals hibernate,from insects to birds and primates.
E.Why,if it is so beneficial,do we not hibernate?
F.The dormice had another reason to stay underground.
G.So many animals fatten themselves up during summer.
分析 本文主要介绍了我们在冬天会觉得困,而动物会更早的进入冬眠时期.他们蛰伏于地下,以保存能量.冬眠对动物是有好处的,而我们人类是不能睡眠那么长时间的.因为动物的冬眠是为了节约能量.
解答 36-40:BEGAF.
36.B联系上下文.根据横线前两句Many of us feel sleepy in winter,but other species often take it a step further and hibernate (冬眠).可知其他动物在冬天会冬眠.横线后句The body slows down and breathing,temperature and metabolic and heart rate all decrease.介绍冬眠的时候,动物的身体特征.横线句必须是连接上下文.B项:They were hibernating underground to save energy.他们蛰伏于地下,以保存能量.符合上下文串联.故选B.
37.E上下文串联.根据横线前两句Hibernation seems to do them good.But human cannot bed down for long periods.可知冬眠对动物是有好处的,而我们人类是不能睡眠那么长时间的.因为动物的冬眠是为了节约能量.E项:Why,if it is so beneficial,do we not hibernate?既然冬眠有这么多好处,那么为什么人类不冬眠的?符合上下文串联.故选E.
38.G语境辨析题.根据横线后句Then they live off body-fat reserves until it's time to wake up.可知冬眠的动物依靠储存在体内的能量过冬.那么前句应该叙述动物在夏天努力储存一定的脂肪以备冬眠消耗.(So many animals fatten themselves up during summer.)故选G.
39.A联系上文题.根据前句But a 2015study of dormice found that they continued hibernating even when cold conditions had ended.可知睡鼠在冬天结束以后还在冬眠.那么肯定存在其他的原因,故A项:So obviously there are other reasons.符合上下文串联.故选A.
40.F承上启下题.根据横线后句By staying out of sight,the dormice avoided being hunted by their predators (天敌) like owls.在介绍睡鼠继续冬眠的其他原因.故F项:The dormice had another reason to stay underground.起着承上启下的作用,符合上下文串联.故选F.
