解析:
(1) A 第一段所叙述的事情发生在白天,句中的dances off maples, spring leaves等语言所叙述的春天阳光明媚的情景,能够跳跃在树影之间的,只有阳光. (2) D 空白后spring leaves已作出提示,树上长的是新鲜树叶. (3) C 在描述了一个春天的阳光明媚的景象后,连词but转折,仔细观察,就发现了麻烦,closer在此是“更仔细”的意思. (4) C 上文叙述了麻烦来自污染,垃圾飘浮在河上,并挂在树枝上.在河上运完木材后,往往有一些剩木头会聚在一个角落,垃圾也会被圈在其中, trapped形象地表现出这种情况. (5) A 由空白后的the next three hours可以确定此空应填介词for,用来表示一段时间. (6) B 此空应填副词even.意思是“甚至”,“连……都”,用来加强语气,在列举了许多垃圾后,强调bowling pins. (7) ahead for表示“向……方向前进”.是固定的动词短语. (8) D 此空填effort表示“欢迎到密西西比河的美化和保护工程”的开始是作为Chad一个人的努力. (9) A 文中Chad's one-man effort已作出提示,此空填副词alone,说明清除密西西比河的污染是Chad一人独自干的. (10) C 该句时间状语At first说明,前边发生的情况后来发生了变化.系动词appear后应为两个并列的消极意义的形容词,说明情况表面看来如此,而事实并非如此,下文所叙述的清理河道的情况正说明了这一点. (11) A 根据下文中的提示backing(支持)可以看出,此空应填supporters. (12) B 根据句型结构,此空应填及物动词,后跟名词作宾语,介词短语作地点状语,有B、C供选择.该句后边的动词不定式to cover a football field表明,这里指把垃圾从河水中拖出,故填pulled. (13) D 根据常识,大部分废物都会被回收利用. (14) B 该句主语是Chad's operation,根据上下文我们知道,这个项目进展顺利,介词短语in progress意为“在进展中”. (15) A 此句是对Chad清理河道行为的一个评价. 从上文我们知道,这个项目开始于1997年,时间并不早,但它坚持下来了,规模并不小,故填biggest. (16) C Chad的行为,鼓励别人向他学习,做同样的事,故填same. (17) D 根据下文对Chad十多岁时,工作在密西西比河并宿营在散落在河道上的岛屿可以确定,此空应填yard,back yard意为“后院”. (18) C 此空设在islands后面, 是修饰islands的,而islands与后面waterway的关系应该是dotting,即“岛屿散落在河道上”. (19) B Chad孩童时在密西西比河上掘蚌,在岛屿上玩儿,这一切带给他的是快乐(joy);在这种情况下“骄傲(pride)”则过分了. (20) A Chad在前边一句说密西西比河使他谋生并给他带来许多欢乐,Chad在后边一句是说自己想为密西西比河做些事情作为报偿.介词短语in return是“作为对……的报答/回报”的意思. |
