参考答案限时规范练9(必修2Unit4)一、【篇章导读】本文是说明文。文章是对瓢虫的介绍。瓢虫是一种能够吃害虫的昆虫,它们对于庄稼来说是得力的助手。1.A推理判断题。由第三段中的“theyareveryhungryandwilleatmites,aphids,mealybugs,greenflies,andothercrop-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“ladybugswerebrought...setfreeamongorangetreesthatweredyingfrombeingeatenbyinsects”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“Veryfewbirdsorinsectswilleataladybugbecauseitgivesoffsomethingthatisdangeroustoeat.”可知,很少有鸟或昆虫吃瓢虫。再由画线部分后的“abirdabout100timesitssize”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standupto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“makeiteasierandsaferfortheblindtofindtheirwayto,intoandthroughbuildingsandlargepublicspaces”可知,这两本书指导人们如何将建筑物建造得方便盲人出入。5.B细节理解题。由第三段中的“Forexample,agoodsignmayincludetactilelettering—Braille”可知,这个系统包括可触摸的标识。6.C细节理解题。由第四段中的“Mostimportantlyhowever,wehavehelpedtoraisetheawarenessandneedforawayfindingsystemacrossthebuildingandconstructionindustry.”可知,获奖使得更多人意识到这一系统的重要性。7.D推理判断题。由最后两段中提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
