C 选项：satisfied 满意的；sorry对不起，难 过；grateful感激的； eager渴望的。作者在13岁 被解雇，以为找不到工作没想到却实现了自己的 梦想，所以应该是感谢那次失业和追求梦想的所 有机会。 15.

B 选项：calm 镇定的; nervous紧张的; confused 迷惑的；interested 感兴趣的。根据前句可知，该 女士的过激反应具有感染力，因为在场的其他顾客 “也”变得紧张兮兮起来。 6. C 选项：put 放好；take拿走；push 推开； carry运走。之前提到该女士想要“除去”蟑螂，现 在终于成功将其“驱赶”。 7. B 选项：fly飞；land着陆；run跑；move移动。 由空格后的介词on可推测出这里表示静态动作，而 不是正在移动。蟑螂又“落在”另一位女士的身上。 8. C 选项：act 表演；change 改变；continue 继续； record 记录。从下文可知第二位女士同样反应激烈， 所以是“延续”这场闹剧。 9. A 选项：rescue 拯救；service 服务；relief 宽 慰；situation 情况。这时，侍应生冲上来“救场、 解围”。 10. A 选项：throw抛,扔；hit拍打；run跑； jump跳。因为顾客们都很慌乱，所以将蟑螂一轮 “抛甩”传递下来。 11.

C 选项：believe相信；imagine想像；wonder 好奇地想知道；consider考虑。下句是一句疑问， 所以是好奇，想知道。 16. B 选项：how 如何；why 为何；what 什么； who 谁。下文解释的是该侍应生不受突发事件困 扰的原因，所以是why。 17. D 选项：hurriedly 急忙地；awfully 糟糕地； slowly 缓慢地；perfectly 完美地。从前文可知， 侍应生处理紧急事件的方式几近“完美”。 18. D 选项：control 控制；prevent 预防；avoid 避免；handle 处理。由下段同样的句式中所使用 的短语deal with可知答案。同时，文章一再强调 人们“处理、对待”事情的态度是混乱的根源。 19. B 选项：gentlemen先生们；ladies女士们； waiter侍应生；audience观众。由前文可知一直是 女士们在夸张地大呼小叫，深受蟑螂困扰。 20. A 选项：reaction 反应；tendency 倾向； contribution 贡献；reference 提及。根据上文蟑螂 事件和作者在现实生活中的事例可知，造成混乱的 不是事件本身，是人对待事情的反应，态度。 (八) 考纲词汇过关 (练前预习，练中理解，练后巩固) in shock ___________ inability n. _______ disturb vt. ______________ prevent v. ______ experience n. ___________ future n. _______ 感到震惊 无能 打扰；妨碍 阻止 经历/经验 将来 occur v. ______ distant adj. _______ century n. _______ generation n. _______ ecosystem n. ___________ effort v. _______ require v. _______ 发生 遥远的 世纪 代 生态系统 努力 要求 I experience no past and no future.

A 选项：as if 好像；unless 除非；in case 万 一；after 之后。家人告诉作者过去发生的事情， 他却觉得“似乎”发生不久。 3. B 选项：forget忘记；keep保持；remind使想 起； suffer遭受。根据语境，作者认为过去的事 情就发生在当下。 4. C 选项：suddenly 突然地；vividly生动地； immediately立刻；perfectly 完美地。将来的事 情也“立即”会发生。 5. A 选项：good 好的；better 更好的；bad 坏 的；worse更坏的。下文提到这样的感觉促使人 们更加注意今天的举止，所以这种感觉作者认为 是“好的”。 6. B 选项：style风格； condition 条件； connection关系； form形式。由下文“provide sustainable conditions for distant generations”提 示可知正确选项。 7. D 选项：skill 技巧；struggle 斗争；problem 问题；concern关心，忧虑。作者认为，如何为 子孙后代提供适宜的环境是今天的我们必须“关 心，忧虑”的。 8. A 选项：determine下决心； enjoy喜欢； benefit获利；ruin毁灭。由语境可知，今天的行 为“决定”子孙后代的健康和财富。 9.

C 选项：take带走，花费；make使，做； cost花费；raise赚钱。由上题可知，保护生态环 境是需要“花费”的。It takes后常接不定式。 12. A 选项：so因此； but 但是；though 虽然； because因为。有人认为既然保护生态需要花费 资金和资源，“所以”不如开发利用。 13. C 选项：permanent 永久的；continuous 持 续的； temporary 短暂的；various多样的。后 面提到“lasts less than a century”，作者认为 开发利用只会持续“短暂的”时间。 14. C 选项：consist of包括；make up 弥补； result in 导致； believe in信任。由上题可知， 作者认为开发利用而不是保护生态，可能会“ 导致”物种的缺失。 15. D 选项：still 仍旧；yet 然而；just 仅仅； also也。不仅是大自然需要保护，我们生活的小 院“也”需要生态保护。 16. A 选项：provide提供；contribute贡献； pay付款，偿还；give 给。动植物可能会给我们 的后代“提供”基因组合。 17. D 选项：disaster灾难；extinction灭绝； flood洪水；diseases疾病。 也许这些动植物的基 因会阻止“疾病”。与or后的“medical advice” 相对。 18. D 选项：trouble麻烦；wish愿望；doubt怀疑 ; chance机会。 根据上句提示“future generations chances for gene splicing”可知，物种 消亡，可能会使后代失去使用基因重组的“机会 ”。 19. C 选项：create创造；offer主动提供；keep持 续；change改变。由句子“past generations that made my present possible. ”提示可知，作者认为 自己能生存是因为祖先留下的环境好，所以，现 在的人们也应该“持续”给后代留下健康的生存 条件。 20. B 选项：come across偶遇；come after紧跟； come about发生；come out出版。由文章大意可知， 作者想给“后代”提供好的生存条件。 THANK YOU!
