22、e four.”(到2050年为止,它将变成四倍)可知,E项“今天,每分钟都会有一卡车的垃圾倒入海洋中”与下一句中提到的数量相呼应。故选E项。2.B空格前面一句话“About 8 million tons of plastic are dumped into the sea every year.”提到塑料垃圾倒入海中,B项“垃圾在海洋中会存在几百年”承接上文。故选B项。3.G根据后文“In addition it produces a huge garbage patch that floats on the surface,thus putting ships in danger and
23、polluting beautiful beaches around the world.”可推知,设空处应讲述塑料垃圾对海洋的负面影响,G项“海洋中的塑料垃圾危及了鱼类群体以及其他海洋动物”符合语境。故选G项。4.C根据前文“Plastic is becoming more and more common in our world.” 可推知,设空处陈述造成这种情况的原因,C项“塑料有很多用途而且生产廉价”解释了其中的原因。故选C项。5.A根据前文“Currently,5% of the worlds oil production is turned into plastic.”可推知,设空
24、处会继续陈述该百分比的情况。A项“到2050年这个比率将上升到20%”承接上文,选项中的it指代上文提到的用来生产塑料的石油所占百分比。故选A项。.【语篇解读】本文是一篇记叙文。文章主要讲述的是一位农民与农场上的浣熊之间发生的既有趣又发人深思的事情。作者种了很多玉米,可是被浣熊破坏了许多,这让作者很苦恼。起初他使用了捕熊的夹子,可是看到小浣熊受伤后自己又很心疼,于是他改变了办法,结果却很奏效。1.C联系空后的“the waste land into fields”可知,作者首先用拖拉机把荒地变成了(changed)良田,以便耕种。2.B根据语意可知,此处表示转折关系,因为接下来介绍浣熊破坏了庄
25、稼,所以选B项。3.D根据下文的“large amounts of corn were eaten”可知,浣熊应该是在收获(harvest)前破坏庄稼,吃掉大量的玉米。4.B根据下文描述的浣熊妈妈给孩子舔伤口的情节可知,在作者走近时,浣熊妈妈为了保护幼崽并没有跑开(run away)。5.D作者伸出(reaching)手,设法给小浣熊松开夹子。6.C根据常识和下文的“and got really upset”可知,小浣熊看到有人靠近,会很不安,因此露出牙齿(teeth)。7.A看到小浣能的举动,为了防止被咬伤,作者给它松开夹子时(as),只好用胶靴压住它的头。8.A联系前文,夹子夹住了小浣熊的
26、腿,因此它的腿受伤了(wounded)。9.C浣熊常到作者的庄稼地里偷吃玉米,为了保护庄稼同时又不伤害浣熊,作者只好采取折中的办法,即在庄稼地(fields)的周围放一些次等的玉米。10.A根据该段中的“damage by the raccoons stopped almost completely”以及下一段中的“we should learn to share”可知,作者放的这些次等玉米都不见了(disappeared)。11.D根据段中的“damage by the raccoons stopped almost completely”可知,除了吃掉这些劣质的玉米,浣熊并没有造成其他的(
27、other)损失。12.B根据“that didnt happen”以及后面介绍的内容可知,作者本以为如果给浣熊提供食物,它们就会进一步烦扰(bother)自己,吃更多的庄稼,但实际上并不是这样。13.C看到自己的投食办法能够很好地保护庄稼,作者决定停止(stop)使用捕兽夹。14.D作者通过放置次等的玉米从而很有效地保护了庄稼,这是一种很奇妙的经历。从这件事中,他见证了自然(nature)的神秘。15.A农民们之所以遭受这种损失,是因为他们想独占(take)一切收成。take在此处为“索取”的意思。.【语篇解读】本文是一篇说明文。文章介绍了气候变化和其他人为活动导致蜜蜂数量的减少,还介绍了养
28、蜂人Thiele独特的养蜂方法及感悟。1.activities考查名词复数。other修饰可数名词复数,故填activities。2.which/that考查定语从句。分析句子结构可知,此处引导限制性定语从句,先行词为chemicals,从句中缺主语,故填关系代词which/that。3.lost考查动词时态。根据时间状语“Last winter”可知,事情发生在过去,应用一般过去时,故填lost。4.a考查冠词。此处修饰可数名词beekeeper,表示泛指“一位养蜂人”,作Thiele的同位语,且beekeeper以辅音音素开头,故填不定冠词a。5.are考查动词时态和主谓一致。此处陈述的是
29、客观事实,用一般现在时;主语为the usual ways,谓语动词用复数,故填are。6.traditional考查形容词。此处修饰名词beekeepers,故填形容词traditional。7.with考查介词。分析句子结构和句意可知,此处应用介词,表示“用”,故填with。8.deeply考查副词。此处修饰动词belong,故填副词deeply。9.to keep考查非谓语动词。此处为it is+adj.+ to do sth结构,表示“做某事是的”,it为形式主语,后面的不定式是真正的主语,故填to keep。10.further考查形容词比较级。根据句意可知,此处有一个隐晦的比较意义,表示“进一步说”,故填further。- 5 -
