解析:

(1) B 下文中在丛林里所携带的指南针已表明,此空说的是为旅行作准备的装备,故填equipment,而tool表示“工具”,一般指做某件工作的用具. (2) B 下文中叙述的在丛林中迷路怎么办,怎样饮水等,均为丛林旅行中应该知道的重要事情. (3) A stay alive表示“生存下来”是一系表结构,alive为形容词作表语.全文叙述的是如何在丛林里生存下来的方法. (4) C 后边一句中的which way to go表明这里所携带的是指南针. (5) D 四个选项均可作及物动词,但只有tell和情态动词can,could,be able to连用,表示“辨别,区分,说清楚”,为最佳选择. (6) C 指南针可用来确定你所处的方向和位置. (7) C 此空填alert意为“警惕的”是形容词,和keep构成系表结构,表示 “保持警惕”.前句Again and again you must alert your position by it. 已作出提示. (8) D 此空填watch表示“监视,密切注意”,与keep alert意思保持一致. (9) B 四个选项的副词性短语,只有now and then表示时间,意为“时而”.stop and listen now and then. 则说明了keep alert的具体方法. (10) B lose one's way表示“迷路”是一动词短语,该段叙述的是迷路后如何找路的方法. (11) B 在密林中迷路就很难存活,所以此空填afraid表示“害怕”,符合迷路者当时的心态. (12) A spot表示“一个特定的地点、场所”,在这里指迷路时所处的那个位置. (13) B 后边一句叙述的在丛林里许多溪流和河流所携带的病菌对人体是致命的表明,在丛林中找到安全饮用的水是一个难以解决的问题,故填problem. (14) D deadly在此是形容词,表示“致命的”,与前面的can be a problem所表达的意思相呼应. (15) C 此处用Luckily表示后边和前边的情况正好相反. (16) C 该句是对全文的总结,说明在丛林中生存是一门科学. Surviving in the jungle是动名词短语作主语. (17) A 四个选项的及物动词都能和what构成“疑问词 + 不定式”结构, 起名词词组的作用在句中作介词宾语,但只有expect表示“对某事作出的预料和思想准备”,与该句的语境相符. (18) C 四个选项均为表示感情的及物动词,其现在分词表示“令人感到……”,但只有frightening和unfriendly意义相近.上下文表示,如果对丛林里发生的不测之事有所准备,它的任何一部分都不会让人感到恐怖了. (19) B 如果你对丛林里所发生的情况,有了思想准备和应对策略,长期在丛林里生活便成为事实,故此空填in fact,在句中作插入语. (20) A live off表示“靠……生活, 靠……供养”,是“动一副”结构的及物的动词短语. |
