答案 八年级地理上册填图题岩土工程勘察试题省略号的作用及举例应急救援安全知识车间5s试题及答案 以及解析1.答案：1-4ABDC解析：1.推理判断题。根据文章第一段中的MobyDickonathree-daycross-countrytraintrip,TheMagicMountaininaNewEnglandbeachsidecottage和TheManWithoutQualitiesonareturntoHawaii可知，这几本 书 关于书的成语关于读书的排比句社区图书漂流公约怎么写关于读书的小报汉书pdf 都是作者在旅途中读的。由此推断作者喜欢在旅行时看书。故选A项。2.词义猜测题。根据文章第二段第三句...setitasideforawhile,andrealisethatIhavetostartoverfromthebeginningagain,havingforgotteneveryone'snameandsocialrank.可知，"我"暂时把它搁在一边，然后意识到自己不得不从头再来，因为"我"忘记了每个人的名字和社会地位。即"我"在读到"战争"那一部分时就没有进展了。由此推断getboggeddown意为"毫无进展"，与makenoprogress意思相近。故选B项。3.细节理解题。根据文章第一段第一句和第二段最后一句可知，作者每年夏天给自己定的目标是读自己年轻时该读而没读的经典文学著作，而自己最喜欢的书很吸引人，但这感觉就像作弊。故作者读他最喜欢的书就像作弊是因为他觉得他应该读些严肃的作品。故选D项。4.主旨大意题。根据文章第一段第一句Istarteverysummerwiththebestofintentions:toattackonebigbookfromthepast,aclassicthatIwassupposedtohavereadwhenyoungandambitious.可知，每年夏天，"我"都抱着最好的打算开始：读完一本"我"年轻且有抱负时就应该读的经典著作。然后下文讲述了今年夏天作者读几本经典著作时的经历。故以"夏天的书"作为标题最恰当。故选C项。2.答案：(1)-(4)ACDB解析：(1)根据第二段中的“Theobjectofourplaywastoobservehowtherockschangedtomissilesastheyrolledtotheroofs’edgeandshotoutintotheyardlikecometsfallingfromthesky.”可知,他们是想看着石头像导弹一样从屋顶的边缘滚下来,就像是彗星从天上掉下来。因此推断孩子们这样做是为了娱乐。故A项正确。(2)根据第一段“IhavecompletelyforgottenthenameofanoldladywhowasacustomeronmypaperroutewhenIwasatwelve-year-oldboyinMarinette,Wisconsinbackin1954.”以及第五段中“Iwouldsavemypaperdeliverymoney”可知,当我12岁的时候,我给人们送报纸。故C项正确。(3)根据第五段可知,作者希望用自己送报纸挣的钱来弥补自己造成的损失。故D项正确。(4)根据第六段“Iwaiteduntilitwasdark,snuckuptotheoldlady’shouse,andputtheenvelopethroughtheletterslotinherdoor.”当我挣得足够多钱的时候,等到天黑的时候我偷偷地溜进老人的家里,我不想老人知道这件事。故该词意为“溜进”,故B项正确。3.答案：1.C;2.B;3.D;4.B解析：1.细节理解题。根据第二段Asforcherries(樱桃),theyaresodeliciouswhocares?可知至于樱桃,它们好吃极了,谁在乎呢?由此判断,作者喜欢樱桃是因为它非常美味,口感极好,故答案为C。2.细节理解题。根据第三段Ifyoulike,asqueezeoffreshlemonjuiceonthebananaswillpreventthemturningbrown.如果你喜欢香蕉上放上新鲜柠檬汁会防止他们变成棕色,可知新鲜的柠檬汁可以保持香蕉原有的颜色,故答案为B。3.词义猜测题。根据下文youcansimplyfeedinfrozenbananasandsomeberriesorslicedfruit及thetopofthemachine.可知,ajuicer在此处的意思是一种机器,用来制作水果冰淇淋,故答案为D。4.推理判断题。本文介绍了很多人喜欢七月是因为这个时间是大量水果上市的季节,接着具体介绍了各种水果所富含的营养成分,及如何制作水果冰淇淋,由此可以判断这篇文章是关于健康饮食,可以从有关健康的杂志看到,故答案为B。4.答案：1.A;2.C;3.A;4.C解析：1.词义猜测题.根据语境义可以看出来,前面有despite是尽管虽然的意思,后半句是doctorsofferedhimalittlehope,医生提供了一线希望,所以他的状况应该暗淡的,无希望的,B选项是不稳定的,C选项是尴尬的,D选项是独一无二的,故答案选A.2.细节理解题.根据第四的第一句Specifically,thetreatmentinvolvedusingthegene-editingtoolCRISPR-Cas9todeleteageneknownasCCR5,whichencodes(给…编码)aproteinthatHIVusestogetinsidehumancells.Withoutthegene,HIVisunabletoentercells具体地说,治疗方法是使用基因编辑工具CRISPR-Cas9删除一个名为CCR5的基因,这个基因编码(给…编码)一种艾滋病病毒进入人体细胞所使用的蛋白质,没有这个基因,艾滋病病毒就无法进入细胞..如果没有这个基因,HIV没有 办法 鲁班奖评选办法下载鲁班奖评选办法下载鲁班奖评选办法下载企业年金办法下载企业年金办法下载 进入细胞,故答案是C.3.推理判断题.根据文章第六段Talkingaboutthegene,leadscientistDengHongkuitoldCNN,"Afterbeingedited,thecells-andthebloodcellstheyproduce-havetheabilitytoresistHIVinfection(在谈到该基因时,首席科学家邓宏奎告诉CNN,"经过编辑后,这些细胞--以及它们产生的血细胞--有能力抵抗艾滋病毒感染.")可知,治疗的结果是一些病人的血细胞可以抵抗HIV感染.故选A.4.推理判断题.根据倒数第二段Dengbelievesgene-editingtechnologycould"bringanewdawn"toblood-relateddiseasessuchasAIDSandsicklecellanemia(镰刀形细胞性贫血)(邓认为,基因编辑技术可以给艾滋病和镰状细胞性贫血等血液相关疾病带来"新的曙光")可知,这个实验可以为血液相关疾病提供一种安全的治疗方法.故选C.5.答案：1.B;2.C;3.A;4.C解析：1.许多公司开发自主机器人的目的是什么?一个个地分析选项,对于A、C和D这三个选项来说,全文都没有提到,B选项中“lastmile”最后一英里是个比喻,原意为完成长途跋涉的最后一段里程,被引申为完成一件事情的时候最后的而且是关键性的步骤,现在是指将家庭和办公室连接到运营商网络和Internet的任何通信连接。根据第一段的“manycompaniesareturningtoautonomousrobotsforthefinallegofthedeliveryprocess,fromthestoreorlocaldistributioncentertothecustomer.”许多公司都在将自主机器人作为配送过程的最后一个环节,从商店或当地配送中心到客户,可以肯定为B选项。A、最后的测试。B、所谓的最后一英里。C、机器人的安全。D、交货速度。2.从第二段我们能推断出侦察机是什么样的?从第二段的“Itspowerfulsensorscanalsodetectthemovementofacarbackingoutofadriveway.”它强大的传感器还可以检测汽车从车道上倒车的运动。可以很快确定答案为C。至于其他三个选项无法从该段体现出来。A、它看起来很酷。B。它会相应地调整速度。C、它的传感器起着关键的作用。D.它将很快得到广
