22、cientist.（分数：25.00）解析：E 考点 考查动词。 该空应填入动词原形，选项中只有E、G和K是动词原形。文章前两句点明向日葵和手机是两种截然不同的东西，这里用But话锋一转，可以推测此处讲的是：你能不能把两者结合起来，因此E项combine“结合”符合文意。解析：D 考点 考查名词。 本题需通读全文，对整篇文章有所了解才能得出答案。由下文的相关信息词biodegradable(生物可降解的)、recycle(回收)等可推断出，本句是说“但是你可以把这两者结合起来为当地环境做些事情吗?”因此D项environment“环境”符合文意。解析：K 考点 考查动词。 根据be able

23、to可判断空格处需填动词原形，综观剩余备选项，G项buy“购买”和K项bury“埋”符合条件。结合句意“当你的手机报废时，你可以把它 -|_|-进花园或花盆，等待它开出花朵。可知K项bury符合文意。解析：A 考点 考查副词。 分析本句的句子结构，空格处所填词充当状语成分且首字母需要大写，符合条件的只有A项Recently“最近，目前”和O项Usually“通常”，结合文意，选项A更贴切。解析：B 考点 考查名词。 结合句意“这种新型手机有望激励 -|_|-进行回收利用”可推知，此空应填表示人的名词，使用手机的人可以统称为“消费者，顾客”，故B项consumers“消费者”符合文意。解析：N

24、考点 考查名词。 前句提到科学家研发了一种新型材料，接着指出“这种新材料像其他 -|_|-一样可硬可软，容易改变形状”，而这正是塑料的特性，故选N项plastic“塑料”。解析：C 考点 考查名词。 本句意为“随着时间的流逝，它也能分解，融进土壤里，而且不会释放出任何有毒的 -|_|-。”根据常识，分解后释放出来的一般是化学物质，因此C项chemicals“化学物质”符合句意。解析：J 考点 考查动词。 本句的时态为一般现在时，该空格所填词为第三人称单数形式的动词，因此选项中只有J项forms“形成”符合文意。解析：F 考点 考查形容词。 根据空格后的名词window推断此处需填形容词，剩余备

25、选项中只有F项transparent“透明的”和N项plastic“塑料的”可选。此外，根据常识可知，只有把窗户设计成“透明”的才便于工程师观察种子的生长状况。解析：I 考点 考查名词。 由句意“但我们(科学家)现在正和植物 -|_|-合作”可知，空格处应填表示一类人的名词，B项consumers“消费者”和I项experts“专家”符合。根据文意，科学家研究过程中的合作对象必定是这方面的植物专家，因此选I。Acasual Bretirement Cto take Dpaid Esubjective Fformal Goverseas Hobjectives Istandardized Jev

31、rk. Many community activities possible in 19 were also possible during ones working life but they are to be undertaken no less seriously for that.

32、轻人在从事全职工作之前有很多 -|_|-志愿服务的机会，发展中国家的一些 -|_|-技术人员也有一些海外服务的机会。”后半句出现了overseas service(海外服务)，属于同义复现，由此推测空格处应填作副词的G项overseas“在海外”。解析：K 考点 考查形容词。 此处意为“发展中国家的一些 -|_|-技术人员也有一些海外服务的机会”，由句子结构可知，空格处应填一个作定语的形容词来修饰technicians(技术人员)。对比各形容词选项可知，K项qualified“有资格的，能胜任的”符合句意，故为答案。解析：D 考点 考查形容词。 由句子结构可知，or前后的两个词应为并列的形容词

33、，且在意义上相反，共同修饰community service，而voluntary意为“自愿的，免费的”，可知空格处所填形容词的意思应为“非自愿的，收费的”，故选D项paid“付报酬的”。解析：J 考点 考查副词。 由句中there are more opportunities than there -|_|- were这一结构可知，than连接的是两个比较成分，比较的是现在的情况和一个人刚开始工作时的情况。此处缺少的就是一个表示过去状况的时间副词，L项never意为“从不”，表示否定意义，不符合上下文语境；J项ever意为“曾经，过去”，符合句意，故答案选J。解析：M 考点 考查形容词。 本

34、句意为“这意味着工作关系与 -|_|-机构的不同，并且价值观念也会不同。”根据上下文可知，本文主要讲社区服务，社区机构必定不同于商业机构、政府机构、军事机构等，而下一句的末尾又出现了commercial criteria“商业标准”，因此此处是指商业机构，选项中符合条件的只有M项commercial“商业的”。解析：A 考点 考查形容词。 空格所在句意为“从某些方面来看，社区机构可能显得更 -|_|-，同时效率也较低，但是我们不应以商业化的标准来评判它们。”根据常识可判断社区机构往往比商业机构更随意、更不正式。空格前为修饰比较级的标志词more，空格后的and连接两个并列的成分，由此判断空格处

35、所填词为形容词且含有“非正式的，随意的”之意，选项中A项casual意为“随意的，非正式的”，符合题意，故为答案；F项formal意为“正式的”，与文意相反，可排除。解析：H 考点 考查名词。 通过分析句子结构可知空格处所填词应是与reasons并列的名词。前文说到社区机构与商业机构的工作关系不同，因此它们的价值观念也会不同，由此可推测这句话是说“那些从事社区志愿服务的人做这些事是出于不同的原因，有不同的目标”，故符合句意的是H项，objectives意为“目标，宗旨”；形近词E项subjective为形容词，意为“主观的；个人的”，与句意不符，可排除。解析：O 考点 考查名词。 由逗号后的n

36、ot可知，commitment to the -|_|-与business efficiency在意思上应该是相对的。这句话是说，成为志愿者组织的一员最重要的是有为“志愿事业”奉献的精神，而不是为了商业效率，故选O项，cause作名词时除了表示“原因”，还可指事业。解析：B 考点 考查名词。 根据上下文，可推测该句的意思是“许多在退休以后做的社区活动在退休前也可以做”，即in -|_|-表示的意义与during ones working life的意义是相反的，in retirement表示退休后，故选B项retirement“退休”。解析：N 考点 考查动词。 该句意为“那些只是想在退休之后

37、寻找一些新鲜事情做的人不应该考虑 -|_|-社区服务。”常用搭配consider doing sth.意为“考虑做某事”，故选N项taking，意为“从事”。A. accustomed B. carefully C. cautiously D. concrete E. credibility F. decayed G. desire H. dimensions I. eligible J. exposed K. indication L. occasions M. permanent N. sensitivity O. translated Fear can be an effective w

46、 teeth，空格处单词与to high-fear warnings共同构成后置定语，修饰subjects，由此判断，此处应填入形容词或分词。前文中提及向被调查对象展示可怕的照片，因此，空格处的信息应表示：看到高度恐惧警示照片的研究对象。结合选项可知，exposed“暴露，显露”符合句意，exposed to表示“接触到的”。故答案为J。解析：B解析 空格前出现动词brush，并且more+空格单词，由此可知，此处应填入副词。副词备选项为carefully“小心地”和cautiously“谨慎地”，结合语境，很明显可知，carefully符合句意，表示“刷牙更仔细”的意思。故答案为B。解析：D解析 由“be given+空格单词+deadlines”可知，此处应填入形容词。备选形容词为eligible“有资格的”，concrete“具体的”，语境为：给人们 -|_|-的指导以帮助他们。结合选项，concrete符合语境，表示“具体的指导”。故答案为D。解析：E解析 由“the+空格单词+of”可知，此处应填入名词。语境为：如果没有做到这些，那么他们就有可能通过否定这些信息或信息传递者的 -|_|-来减轻焦虑。可选名词中credibility“可信度”符合语境。故答案为E。
