答案

一、单语法填空

1.illegal句意:误报火警是违法的，可能会导致监禁。illegal意为“违法的"。

2.behuntedon后跟的是what引导的宾语从句，what在从句中作主语，what与hunt之间是被动关系，且由前面的情态动词可判断用behunted。句意:几千年来，他们开始减少对野外狩猎和采集的依赖，更多地依靠自己饲养的动物和播种的庄稼。

3.immediately副词修饰动词短语makemydecision。句意:我不能立即作出决定，但你很快就会听到我的消息。

4.outdieout灭绝，逐渐消失。句意:加利福尼亚秃鹰吸引了研究人员的兴趣，因为它们在20世纪80年代几乎灭绝。

5.anatarateof.........的比率，......的速度。average读音以元音音素开头，故其前用an。句意:这24个国家有大约30亿人口，他们的收入平均以5%的速度增长，而发达国家只有2%。

二、完形填空

[语篇导读]北极熊生活在北极圈和一些广阔的陆地上，南至纽芬兰。由于对北极熊活动范围的研究甚少,很难计算出全球北极熊的数量;然而,生物学家计算出全世界大约有2万到2.5万头北极熊。

1.that考查名词性从句。句意为:虽然它们很少出现在北纬88度(的地区),但有证据表明，它们的活动范围遍及北极地区，甚至南至加拿大的詹姆斯湾。根据句意及设空前的evidence可知,此处应填的是同位语从句的引导词。再分析设空后的句子成分可知，从句不缺成分，且句意完整，因此应用that引导该同位语从句。故填that。

2.poorly考查词性转换。句意为:由于对北极熊活动范围的研究甚少，很难计算出全球北极熊的数量....设空处修饰动词studied,应用副词。故填poorly。

形容词和副词的基本用法:

(1)形容词可作定语、表语和补语:常位于名词前，作定语,修饰名词;位于系动词之后,作表语;位于宾语之后,作补语。(2)副词在句中常作状语，用于修饰动词、形容词、副词或句子。

3.of/for考查介词。句意为:追踪北极熊数量的现代方法从20世纪80年代中期才被运用,而且在大面积范围内持续进行的成本很高。methodof/for(doing)...为固定搭配,意为"做.....方法。故填of/for。

4.toperform考查非谓语动词。句意见上一题解析。根据"主语+be+adj.+todo"结构可知，此处应用动词不定式,其中动词不定式用主动形式表被动意义。故填toperform。

5.havereported考查动词的时态。句意为:近年来，努纳武特的一些因纽特人报告说，在人类居住地附近看到熊的次数有所增加,这让人们以为熊的数量正在增加。根据时间状语Inrecentyears可知,本句应用现在完成时。故填havereported。

6.belief考查词性转换。句意见上一题解析。设空处作介词to的宾语，且其前有不定冠词a限定，其后有同位语从句修饰，应用名词形式。故填belief,意为“观点;信念”。

7.noting考查非谓语动词。句意为:科学家们已做出回应，称饥饿的熊可能聚集在人类居住地附近，导致了熊的数量比实际数量要多的错觉。设空处作介词by的宾语,应用动名词形式。故填noting.

(1)note如果是名词，意为“笔记;便签;字条;音符;注解;钞票”,设空后的从句不好解释。(2)by作为介词，表示“通过”时后常加动词的-ing形式(除非是固定短语,如byhand,bymeansof)。(3)本题解题(在不确定note的意思，或者混淆了和notice意思的前提下也几乎不会影响考生做题)的思路和重点应该关注前面的介词by,by+doing是本题的考点,意为“通过
