30、.（分数：40.00）(1).【C1】（分数：2.00）A.data B.lectureC.commentD.stress解析：解析：第一段谈到我们相信在银河系里有类似地球的行星；空格后又谈到了 NASA 的望远镜以及观察到的行星数量。这些都归为“数据，资料”，因此选 A 项。(2).【C2】（分数：2.00）A.flexibleB.accessibleC.remarkable D.renewable解析：解析：空格处形容词修饰 Kepler satellite(开普勒太空望远镜)，说明其特征。从后面的数据“15 万颗行星”可以看出，该望远镜对天体的研究意义是非常杰出的。C 项 remarka

31、ble“卓越的，杰出的”符合语义要求。(3).【C3】（分数：2.00）A.creatingB.comprising C.unitingD.merging解析：解析：空格处动词以现在分词形式出现，引导 some 150,000 stars，修饰 an area of the sky。B 项 comprising 的原形动词 comprise 表示“包括，由构成”，可以反映出“天体中聚集着许多星星”的事实，符合语义要求。(4).【C4】（分数：2.00）A.asB.to C.withD.like解析：解析：所需介词应能搭配 similar 表示“与相似”之意，说明“约有 5的行星具有跟地球相似的

32、质量”。选项中只有 B 项 to 符合用法上的要求。(5).【C5】（分数：2.00）A.whenB.untilC.asD.if 解析：解析：一般认为，适宜居住(habitable)的星球需要有水，也只有在有水的前提下，才有存在液态水的可能。由此可推断 they hold water 是 it has a high chance of being liquid 的前提条件。D 项if“如果”符合句子的语义和逻辑要求。(6).【C6】（分数：2.00）A.ProvidedB.HenceC.Since D.Unless解析：解析：结合本段首句中提到的“科学家估计约有 5的行星具有跟地球相似的质量”

33、，可以认为此句逗号前的分句“单单在银河系中就存在大约 2,000 亿颗恒星”是逗号后句子“科学家们估计大约会有100 亿颗地球体积大小的行星存在”的依据。C 项 Since 可引导原因状语从句，指“由于，因为”，用法、语义均符合要求。(7).【C7】（分数：2.00）A.promiseB.demandC.defineD.assume 解析：解析：上句谈到科学家估计(estimate)的情况，本句 that 后面的内容依然是科学家推测的情况。选项中，D 项 assume“假设，设想”指在缺乏证据的情况下也认为某事是真实的，语义和用法均符合要求。(8).【C8】（分数：2.00）A.absurdB

34、.imaginaryC.invisibleD.alien 解析：解析：此段在谈论银河系(galaxy)中宜居星球的情况。空格所在的短语位于介词 in 后面，表明生命体可存活的地点。D 项 alien“外星人”可作形容词用，意为“外星人的，陌生的”，搭配 world 可指“外星球”，即地球以外的空间。(9).【C9】（分数：2.00）A.subtle B.cheerfulC.emotionalD.casual解析：解析：空格后表原因的 since 提到决定生命条件的因素：什么是生命体、生命体如何出现在这个行星之上，以及该行星的地质史。可见生命存在的条件相当复杂。A 项 subtle“微妙的，难以

35、捉摸的”的语义符合要求。(10).【C10】（分数：2.00）A.instead ofB.except thatC.as well as D.in terms of解析：解析：since 引导的原因状语从句表明其后的内容都是决定生命条件的因素，空格后的该行星的地质史也是其中之一。故选 C 项 as well as“也”。(11).【C11】（分数：2.00）A.Claims B.DoctrinesC.ApproachesD.Orthodoxies解析：解析：根据该句最后一个单词 tentative“不确定的”，可知这里说的地球生命出现在 38 亿年前是一种断言。A 项 Claims 常指无法提

38、assemble解析：解析：一般认为，地球自身的重量、单月卫星以及磁场是使得复杂生命体得以在地球上存活和繁衍的部分因素。B 项 thrive“兴盛、茁壮成长”代入后可指生命体在地球表面上存活并发展，符合语义要求。(16).【C16】（分数：2.00）A.BehindB.AlongC.OverD.Without 解析：解析：空格所在句的过去时态(would find)是虚拟语气的用法，意为“复杂生命体将难以生存”。空格后的 these 指代的是上句中的 Earths heavymagnetic field 等复杂生命体赖以生存的条件。D 项 Without 可表示因为缺少某个条件而引出一个虚拟的

39、结果。(17).【C17】（分数：2.00）A.evolve B.persistC.degenerateD.ripen解析：解析：上段中提到在量初的 30 亿年里，地球上的生命体基本是单细胞。直到大气层中充满氧气才出现更复杂的生物体。这是一个逐渐进化的过程，A 项 evolve“进化”符合要求。能和其后的survive“生存”构成语义并列。(18).【C18】（分数：2.00）A.riskB.libertyC.privilege D.objective解析：解析：该段第一句谈到来自开普勒太空望远镜项目的结果令人鼓舞和振奋，正是因为开普勒太空望远镜和它所提供的资料，我们才能享有这样的殊荣去求证地

40、外世界的存在。C 项 privilege“特权，殊荣”符合上下文语义。(19).【C19】（分数：2.00）A.suspectB.pledgeC.celebrateD.conclude 解析：解析：根据空格前的 Based on these findings，可知空格后的内容为基于发现所得出的结论。D项 conclude“推断，认定”符合前后语义要求。(20).【C20】（分数：2.00）A.rare B.popularC.naturalD.new解析：解析：However 表转折，由此应推测科学家认为在银河系或是在其他星系中地球支撑如此复杂的生命体的能力是不同寻常的。A 项 rare“罕见的

41、，特殊的”符合。For decades the market for expensive headphones was mainly limited to hi-fi fans.
