这是一篇说明文。文章讲了帝王蝶这种蝴蝶的数量在下降,造成它们数量下降的原因、它们的重要性以及人们可以做些什么去拯救它们。
【1】考查动词时态。句意:他们在2018年秋季的帝王蝶得到了一个令人担忧的结果。2018年是过去时间,谓语动词用过去式,故填got。
【2】考查固定短语。句意:自从2017年帝王蝶的数量已经下降了86%。短语the number of...“......的数量”,故填the。
【3】考查固定短语。句意:橙色和黑色相间的帝王蝶因它们的长途迁徙而闻名。短语be famous for...“因......闻名”,故填for。
【4】考查副词。句意:帝王蝶和大多数蝴蝶一样,对植物非常重要。terrible意为糟糕的、非常严重的,是形容词,important意为重要的,是形容词,用副词修饰,terrible的副词形式是terribly,意为很、非常,故填terribly。
【5】考查非谓语动词。句意:它们完全依赖一种叫做乳草的植物产卵。短语depend on...to do...“依靠......去做某事”,to do不定式表目的,故填to lay。
【6】考查非谓语动词。句意:随着越来越多的野生土地变成大型农场,帝王蝶很难找到足够乳草。have trouble doing...“做某事有困难”,故填finding。
【7】考查定语从句连接词。句意:许多农场也使用杀虫剂来杀死昆虫,以保护他们的植物。chemicals在此指化学药品,是定语从句的先行词,定语从句中少主语成分,用关系代词,代指前面的名词并且指物应该用关系代词which/that,故填which/that。
【8】考查形容词比较级。句意:此外,污染使得乳草对帝王蝶的健康状况不如从前。less应修饰形容词比较级,health意为健康,是名词,其形容词形式是healthy,意为健康的,健康的的比较级是healthier,故填healthier。
【9】考查动词时态语态。句意:科学家表示,如果不采取措施拯救帝王蝶,它们将在未来20年面临灭绝的危险。此处事情是被做,用被动语态,结构为be done,if引导的条件状语从句用一般现在时,nothing意为什么也没有,谓语动词用单数,be动词的单数形式是is,故填is done。
【10】考查名词的数。句意:人们可以做的事情包括种植乳草,控制化学品的使用,保护野生地区,植树。后面列举出了很多人们可以做的事情,故此处可数名词thing用其复数形式,句首单词首字母大写,故填Things。
