36、ial Intelligence, but he was (2) the author of another signal achievement. In the 1950s, he built a revolutionary light microscope that enabled him to (3) successfully deeper layer in a specimen with astonishing clearness, (4) first having to undertake the hard task of cutting the specimen into thin

40、B. atC. as D. in（分数：1.00）A.B.C. D.解析：解析 词义辨析题。常与 famous 搭配的介词有 at 和 for。be famous at 意为“是的名手，善于”，be famous for 意为“因而著名”，表示原因。但这两个介词用在这里都不合适，原文意为“Minsky 以人工智能之父而闻名”，应用表示“作为，当作”之意的介词 as，故选 C。(2).A.too B. eitherC.even D. also（分数：1.00）A.B.C.D. 解析：解析 语法结构题。also 表示肯定，多用于句中或句末；too 表“也”之意时，一般用于句末，且用逗号隔开，eit

41、her 通常用于否定句中，故正确答案为 D。(3).A. view B. makeC. bring D. grow（分数：1.00）A. B.C.D.解析：解析 词义辨析题。结合常理可知，显微镜通常用于观察标本，故四个选项中 view“观察，观看”符合题意。(4).A.with B. withoutC.and D. but（分数：1.00）A.B. C.D.解析：解析 逻辑衔接题。由上文的信息词 successfully 和 with astonishing clearness 及下文的undertake the hard task 可推知，因为能成功看清，就不用做后面提到的 hard tas

42、k 了，without 符合题意。(5).A. parts B. sectionsC. groups D. separations（分数：1.00）A.B. C.D.解析：解析 词义辨析题。part 指整体的一部分；section 强调整体下的“部分”，往往暗示部分与部分间有明显的界限；group 意为“一群”；separation 意为“分离，分开”。B 符合句意，原句意为“将标本切成小段”。(6).A. accept B. bringC. achieve D. earn（分数：1.00）A.B.C.D. 解析：解析 词义辨析题。accept 意为“接受”，bring 意为“带来”，achi

43、eve 意为“完成，达到”，earn 意为“赢得”，原句意为“在那个时候 Minsky 的发明并没有赢得公众广泛的赞誉”，故选 D。(7).A. As a result B. HoweverC. In fact D. Nevertheless（分数：1.00）A.B.C. D.解析：解析 逻辑衔接题。上文提到当时他的发明并未广受赞誉，再结合下文可推知，这是因为很少人知道显微镜的用途，故下一题答案为 A。同时，可知“很少人知道”是“未广受赞誉”的原因，而非结果，排除 A，而且两句间无转折关系，故 B 和 D 可排除，只有 C(实际上)最合题意。(8).A. few B. littleC. man

44、y D. most（分数：1.00）A. B.C.D.解析：解析 词义辨析题。解析见上题。(9).A. techniques B. worksC. inventions D. instruments（分数：1.00）A.B.C.D. 解析：解析 词义辨析题。根据上下文可知，此处说的是“同类设计的仪器”，故应选 D。其余的选项techniques(技术)，works(作品)，inventions(发明)均不合题意。(10).A. Unexpected B. UnappreciatedC. Undone D. Uninformed（分数：1.00）A.B. C.D.解析：解析 词义辨析题。由下文

45、leaving his intention to rust 可知，他对自己的东西并不满意，故应选 B(不欣赏)。其余的选项 unexpected“不期望的，不指望的”，undone 为“未做完的”，uninformed“不知道的”均不合题意。(11).A. engaged B. ignoredC. moved D. proceeded（分数：1.00）A.B.C. D.解析：解析 惯用搭配题。四个选项中能和 on to 构成搭配的只有 C，move on to 意为“转移(到新事物上)”。(12).A. angle B. comer C. quarter D. side（分数：1.00）A.B

46、. C.D.解析：解析 词义辨析题。angle 指数学概念的“角，角度”，corner 指角落或拐角处，quarter 指“四分之一”，side 指“边”，结合句意，B 正确。(13).A. otherwise B. orC. but D. however（分数：1.00）A. B.C.D.解析：解析 语法结构题。此处需要填入的是副词，由此可排除 B 和 C。otherwise 意为“以别的方式，不同地”，however 意为“无论如何，究竟”，结合句意“十三年后，他的方法_大家所知的双焦显微镜学引起了公众的注意”，可知 A 正确。(14).A. However B. ForC. Indeed

47、 D. Hence（分数：1.00）A.B.C. D.解析：解析 逻辑衔接题。由上文的 caught public attention 和下文的 one of the most exciting advances 可知，两者间并无转折或因果关系，而是强调，故 indeed(确实)符合句意。(15).A. in B. toC. for D. by（分数：1.00）A.B.C. D.解析：解析 惯用搭配题。to 和 extent 为固定搭配，如：to a certain/some extent“在某种程度上”，to a great/large extent“在很大程度上”，本句中 to 和 whi

48、ch 构成“介词+which”结构作 extent的关系词。(16).A. job B. workC. occupation D. profession（分数：1.00）A.B. C.D.解析：解析 词义辨析题。四个选项中，job 指具体的“某一份工作”，常为可数名词；work 意为“工作”，常为不可数名词；occupation 和 profession 均表示职业，结合句意可知 B 正确。(17).A. For B. IndeedC. Generally D. Nevertheless（分数：1.00）A.B.C.D. 解析：解析 逻辑衔接题。由上文的 not completely clea

49、r 及下文的 the happy result 等信息词可推知，此处应填入表转折关系的词，故 never the less(尽管如此)正确。(18).A. same B. differentC. opposite D. contrary（分数：1.00）A.B. C.D.解析：解析 词义辨析题。scores of 含义为“几十个”，由此可推知后面应为“各种不同的”，故选B。(19).A. desirable B. considerableC. available D. reliable（分数：1.00）A.B.C. D.解析：解析 词义辨析题。desirable 意为“称心的，合意的”，considerable 意为“数量可观的”，available 意为“可用的，可得到的”；reliable 意为“可靠的，可依赖的”，结合句意可知 C 正确。(20).A. differ B. extendC. change D. ra
