15．Everyone has heard of Groundhog Day （土拨鼠日）．（26）A．People in America think that the groundhog awakens from its winter's sleep on February 2nd．The groundhog comes out of its hole．If the sun is shining，it will see its shadow．The shadow scares it．So it runs back into its hole．This means six more weeks of winter．If the day is cloudy，it will not see its shadow．Since it is not scared，it stays out of its hole．（27）C．These are the same things we say on Groundhog Day today．
（28）B．They are known mainly to country people．City people just don't know how to look for them．City people think that a groundhog sitting by its hole may look like a root（根）．It could also be seen as a clod （块） of earth．Or it may look like a broken fence-post（栅栏柱）．But a farmer sees groundhogs anywhere he looks．They'll be watching like guards．
The groundhog is a native American．（29）F．It may also appear as far north as Alaska．It is hated by farmers．The groundhog eats a third of its weight in a day．What a big appetite（胃口）！It may eat about a half-ton of alfalfa（苜蓿） in a summer．So 10 groundhogs in a big field would eat five tons．
Why do groundhogs eat so much？To prepare for winter．（30）E．This extra food is changed to fat．This fat is what they live on during their long winter's sleep．
A．It is an American holiday．
B．Groundhogs are strange animals．
C．This means that spring will soon come．
D．There are several ways to protect the groundhog．
E．In the fall，when there is a lot of food，they fill up．
F．It is found in most states east of the Rockies（落基山脉）．
G．While it is not one of your major holidays，it is one that children love．
分析 本文主要介绍了土拨鼠日，它是美国的一个节日．当土拨鼠不害怕时，它们就会呆在洞外，这就意味着春天快要到来了．而在秋天的时候，它们会吃很多食物，额外的食物会变成脂肪，而这种脂肪在它们漫长的冬眠里供给能量．
解答 ACBFE
26．A 联系上文题．空前Everyone has heard of Groundhog Day （土拨鼠日）．译为：每个人都听说过土拨鼠日，这里选A（它是美国的一个节日．）与上下文一致．故选A．
27．C语境理解题．空前Since it is not scared，it stays out of its hole．的意思是：因为它不害怕，所以就会呆在洞外．所以这里选C（这就意味着春天会很快到来．）与上下文一致．故选C．
28．B衔接下文题．空后的意思是：主要是乡村人熟悉它们．所以这里选B（土拨鼠是奇怪的动物．）与上下文一致．故选B．
29．F承上启下题．空前The groundhog is a native American．句意：土拨鼠是本土美国动物．空后It may also appear as far north as Alaska．句意：它也可能出现在北部远至阿拉斯加．所以这里选F（落基山脉东部大部分的州能找到土拨鼠．）与上下文一致．故选F．
30．E上下文衔接题．空前Why do groundhogs eat so much？To prepare for winter．句意：为什么土拨鼠吃这么多？准备过冬．空后This extra food is changed to fat．This fat is what they live on during their long winter's sleep．句意：额外的食物变成脂肪，这种脂肪在它们漫长的冬眠里供给能量．选项E：In the fall，when there is a lot of food，they fill up．在秋天的时候，有很多食物让它们填补肚子．故选E．
