Question

【题目】 Each summer, Craig Stihler and Jack Wallace, scientists for the state of West Virginia hike to Peacock Cave to count Virginia big-eared bats. 【1】. They want to see if the number of bats is going up or down.

I was there to learn about the bats for my book. After we arrived at the small entrance to Peacock Cave, Craig and Jack unpacked their equipment. Crale said, “【2】 .Hibernating (冬眠)bats may be awakened and fly around and burn up the fat they've stored in their bodies. Without that food supply, they might not live until spring when they can eat insects again. And bat mothers may drop their babies. “

As night settled in，they set up a night-vision scope (观察仪器）.【3】 .They also set up a radio-like bat detector outside the cave. It picks up bat sounds that our ears can’t hear. For the next two hours, Craig counted the bats by speaking into a handheld voice recorder each time five bats flew out of the cave. By the time the last bat left the cave at about 10:30 p. m., Craig and Jack had counted 1,242 bats! 【4】 .Craig explained that when the first count was taken at Peacock Cave in 1983, there were only 160 Virginia big-eared bats. Projects to help protect bats have helped the bats make a remarkable comeback. Today the total number of Virginia big-eared bats there are more than 25,000.

【5】 .They will continue to need human’s help if they are going to survive into the future.

A.Why do they do so?

B.It allows them to see the bats in darkness.

C.Virginia big-eared bats are medium-sized.

D.Bats are important because they eat insects.

E.They want to catch some bats for their research.

F.Bats living in caves can suffer if disturbed by people.

G.That was the most Craig and Jack had ever counted there.

【1】A

【2】F

【3】B

【4】G

【5】D

【解析】

这是一篇记叙文。文章讲述了作者跟随科研人员去山洞里统计一种蝙蝠的数量，了解到近年来由于受到人类的保护蝙蝠的数量有所回升。

【1】空白前句指明了科学家们每年夏天会去统计蝙蝠的数量，后句则交代了这样做的意图，A选项“他们为什么要这么做呢？”承上启下，语义通顺。故选A项。

【2】空白处是Crale准备进洞穴进行观测之前说的一句话，下文继续说明如果蝙蝠冬眠被吵醒可能导致的一些不良后果，也就是在提醒最好不要打搅、惊扰蝙蝠，F选项“住在洞穴里的蝙蝠如果被人打搅会遭受不好的结果”符合文意。故选F项。

【3】空白前句指出科研人员架设了夜视的观察仪器，B选项“这使得他们能在黑暗中看到蝙蝠”解释了仪器的作用，符合文意。与接下来两句的行文结构是一致的。故选B项。

【4】空白前句用感叹号强调了观察到的蝙蝠数量之多，后句也在解释蝙蝠数量在人们的帮助下逐渐回升。G选项“这是Craig和Jack在那里统计过蝙蝠数量最多的一次”上下连贯，符合文意。故选G项。

【5】空白处置于最后一段末尾，后句表明只有在人类的帮助下蝙蝠才能继续存活，这里they就指代蝙蝠，而D选项“蝙蝠吃昆虫所以它们很重要”就以蝙蝠为主语，强调其重要性，逻辑和结构上都符合要求。故选D项。

七选五题型主要考查考生对文章的整体理解和掌握情况，相当于阅读理解和完形填空的综合。它不仅需要阅读速度，还要对文章的结构、主旨、写作意图、观点都有所了解。主要考点包括：1.考查主题句，也就是考查对文章整体内容的概括能力；2考查上下文衔接，即考查文章的过渡部分；3考查中心句，需要考生学会归纳段落大意。拿到题目时，应该先确定出题位置；读题干，再读需要填入句子的上下句，画出关键词；读文章各段落，确定段落中心句和文章主题句；通读文章确定上下句和选项之间的逻辑关系。针对不同设空位置选择不同的策略就能事半功倍。第3小题就是一个典型例子，前句+空白处的句子的结构与接下来的两句话结构是完全一致的（因其句中有also一词），先描述现象再解释原因，据此就可以推断出正确答案。
