28、-destroyers”可知,这些都是对庄稼有害的虫子。2.A细节理解题。由第四段中的“ladybugs were brought.set free among orange trees that were dying from being eaten by insects”可知,19世纪瓢虫被从澳大利亚引进到美国加利福尼亚州是为了挽救被害虫侵害的橘子树。3.D词义猜测题。由倒数第二段中的“Very few birds or insects will eat a ladybug because it gives off something that is dangerous to eat.”可

29、知,很少有鸟或昆虫吃瓢虫。再由画线部分后的“a bird about 100 times its size”可知,当遇见比它大的鸟时,瓢虫会释放某种物质从而对鸟造成威胁。故此处的stand up to有“回击,抵御”之意。【篇章导读】本文是说明文。文章介绍了一项帮助盲人识别道路、进出大楼和公共场所等的项目。4.C细节理解题。由第一段中的“make it easier and safer for the blind to find their way to,into and through buildings and large public spaces”可知,这两本书指导人们如何将建筑物建造

31、到的这两本书在不同地方的可参考性可以推断,Ron认为这两本书是很好的指南类书籍。二、【篇章导读】本文是议论文。要不要参加课外活动对于许多学生来说是个需要权衡利弊的问题。1.E本空为本段的主题句,本段主要阐述了参加课外活动的学生们在学习方面表现更突出,即参加课外活动的好处。2.F本空是对前一句的举例说明,且下一句中的we became friends与F项中的I met my best friend在语意上相关。3.C由本空前一句可知,本段开始阐述参加课外活动的弊端;而本空后面的内容是对本空的进一步解释说明,阐述的是其中一个弊端,即让学生们更繁忙。4.BB项内容与下一句形成因果关系,本空后面的T

32、his situation指代B项内容。5.G本空前一句与G项内容形成转折关系,即课外活动虽有好处,但学生们需要恰当巧妙地安排时间,以应对繁忙的生活。三、1.were found考查一般过去时的被动语态。设空处所在句意为“一百多年前,从美国的西南部到阿根廷都能发现美洲豹的踪影”,故find与jaguars之间是被动关系,应用被动语态,且由A hundred years ago可知,此处应用一般过去时,故填were found。2.natural考查形容词做定语的用法。设空处做定语修饰habitat,表示“自然的”,故填形容词natural。3.mostly考查副词。设空处做状语修饰谓语动词li

33、ve,表示“主要地”,故填副词mostly。4.to考查介词。according to 意为“按照,根据所说”。5.is考查主谓一致。设空处所在句描述现在的情况,应用一般现在时,因为主语是habitat loss,故填is。6.scientists考查名词复数。设空处做主语,表示“科学家”,因为scientist是可数名词,由Most及谓语动词agree可知,此处应填scientists。7.an考查不定冠词。设空处所在句意为“树木在影响气候变化方面起着重要作用”,故填an。play an important role in.“在方面起重要作用”。8.trapped考查过去分词做表语的用法。设空处所在句意为“森林面积的减少意味着越来越多的温室气体停留在大气层里”,trap与greenhouse gases之间是被动关系,故填过去分词trapped。9.have disappeared考查现在完成时。由since a hundred years ago可知,此处应用现在完成时,因为主语是half of the worlds wetlands,故填have disappeared。10.or考查连词。either.or.“或者或者”。
