单选题今天，许多最好的科学研究工作都揭示：许多早些时候被认为是正确的科研工作的结果，实际上都是错误的。然而，尽管科学家们首要关心的事情是发现真理，但是对今天的科学家来说，研究早期科研工作的第一手报道仍是非常有价值的。 下面哪一项，如果正确，能最好地使上面的两个陈述相一致?

单选题有些教员也拥有了私人汽车，所有的大款都有私人汽车。因此,有些教员也是大款。以下哪个推理具有和上述推理最为类似的结构?

单选题The proper way to plan a scientific project is first to decide its goal and then to plan the best way to accomplish that goal. The United States space station project does not conform to this ideal. When the Cold War ended, the project lost its original purpose, so another purpose was quickly grafted onto the project, that of conducting limited-gravity experiments even though such experiments can be done in an alternative way. It is, therefore, abundantly clear the space station should not be built. The reasoning in the argument is flawed because the argument

单选题专家：上市公司的董事会通常由大股东组成，小股东因股权小不能进入董事会，因此小股东的利益很容易受到大股东的侵犯。设立独立董事制度，是希望独立董事能够代表小股东，形成对大股东的制衡。但独立董事由公司董事会聘请并支付报酬，这就形成了独立董事与公司董事会在经济上的“同盟”关系，使得独立董事很难站在小股东立场上行使独立董事的权力。 如果以下陈述为真，哪一项最有力地支持了上述专家的结论? A．许多退休高官担任了中国上市公司的独立董事。 B．有些独立董事敢于维护小股东的利益诉求，尽管会受到很大压力。 C．如果独立董事为了维护小股东的利益而与公司董事会叫板，其结果往往是被公司董事会解聘。 D．目前，中国上市公司的独立董事制度尚不健全。

单选题6—8基于以下题干： 贾女士：一项权威性的调查数据显示，在医疗技术和设施最先进的美国，婴儿最低死亡率在世界上只占第17位。这使我得出结论，先进的医疗技术和设施，对于人类生命和健康所起的保护作用，对成人要比对婴儿显著得多。 陈先生：我不能同意您的论证。事实上，一个国家所具有，的先进的医疗技术和设施，并不是每个人都能均等地享受的。较之医疗技术和设施而言，较高的婴儿死亡率更可能是低收入的结果。

单选题在上题断定中再增加如下断定： “有的北方队员是大学一年级学生”，并假定这些断定都成立，那么，下列哪项断定必定为假?

单选题铝合金在军用装备上广泛地取代了钢，因为它能提供同样的防护而重量更轻。但是一辆铝合金装甲车的制造成本是钢装甲车的两倍。因此，从财政的角度看，用具有同样防护性能的铝合金装甲车来代替钢装甲车的做法是不可取的。 以上哪项为真，能够对上述结论提出最大的质疑?

单选题科学院：研究已经证明使用自然方法可以使一些管理经营良好的农场在不明显降低产量，甚至某些情况下可以在提高产量的基础上，减少合成肥料、杀虫剂以及抗生素的使用量。 批评家：不是这样的，科学院选择用以研究的农场似乎是使用自然方法最有可能取得成功的农场。那些尝试了这样的自然方法且失败了的农场主会怎么样评价呢? 下面哪一项是对批评家应答的逻辑力量的最充分的评价? A．农业上的成功和失败很少仅仅因为幸运与否，因为农业就是对或然事件的管理。 B．那些批评家表明如果被研究的农场的数量加倍，那么研究的结果将会不同。 C．那些批评家毫无理由地假设那些失败不是由土壤质量引起的。 D．被讨论的问题仅仅是为了展示某些事情是可能的，所以与被研究的例子是否具有代表性并无关系。

单选题国产影片《英雄》显然是前两年最好的古装武打片。这部电影是由著名导演、演员、摄影师、武打设计师和服装设计师参与的一部国际化大制作的电影。票房收入的明显领先说明观看该部影片的人数远多于进口的美国大片《卧虎藏龙》的人数，尽管《卧虎藏龙》也是精心制作的中国古装武打片。 为使上述论证成立，以下哪项是必须假设的? Ⅰ．国产影片《英雄》和美国影片《卧虎藏龙》的票价基本相同。 Ⅱ．观众数量是评价电影质量的标准。 Ⅲ．导演、演员、摄影师、武打设计师和服装设计师的阵容是评价电影质量的标准。

单选题地理学家和历史学家过去一直持有的观点认为，南极第一次是在1920年左右被发现的，但是某些16世纪的欧洲地图上显示着与极地相似的一片地域，虽然那时的探险家从未见到过它。因此有些学者争论说该大陆是被古代人发现并画到地图上的，而大家知道这些古人的地图曾为欧洲绘制地图者起到了模型的作用。下面哪项如果正确，最能削弱上面学者所得的推论?

单选题In a survey of consumers in an Eastern European nation, respondents were asked two questions about each of 400 famous Western brands: whether or not they recognized the brand name and whether or not they thought the products bearing that name were of high quality. The results of the survey were a rating and corresponding rank order for each brand based on recognition, and a second rating-plus-ranking based on approval. The brands ranked in the top 27 for recognition were those actually available in the nation. The approval rankings of these 27 brands often differed sharply from their recognition rankings. By contrast, most of the other brands had ratings, and thus rankings, that were essentially the same for recognition as for approval. Which one of the following, if each is a principle about consumer surveys, is violated by the survey described?

单选题电视节目编排专家一直认为一家电视台黄金时段的收视率每增加一个百分点，收看该电视台晚间新闻节目的观众人数就会增加三个百分点。然而，罗姆电视台在过去的十年里仅仅有一年其黄金时段的收视率特别高，可是这一年收看该电视台晚间新闻节目的观众人数却也是历年最少的。 下面哪一个结论可以从上文所提供的信息中被正确地推出? A．当一个新闻节目赢得很出色的收视率时，推出该节目的整个电视台的收视率也将表现得很出色。 B．电视节目编排专家忽视了对白天新闻节目的考虑。 C．罗姆电视台有一年收视率之所以特别高是由于该电视台播出一部畅销电视剧，该电视剧后来却由于合同问题被停止在该台播映了。 D．黄金时段的收视率并不是决定有多少观众观看晚间新闻节目的唯一影响因素。

单选题Conservationists have believed that by concentrating their preservation efforts on habitats rich in an easily surveyed group of species, such as birds, they would thereby be preserving areas rich in overall species diversity. This belief rests on a view that a geographical area rich in one group of species will also be rich in the other group's characteristic of the entire regional climate zone. Which of the following findings about widely scattered tracts 10 kilometers by 10 kilometers in a temperate climate zone would most seriously challenge the conservationists' assumptions? (A) The tracts show little damage from human intrusion and from pollution by human activities. (B) Where a certain group of species, such as birds, is abundant, there is also an abundance of the species, such as insects, on which that group of species feeds, or in the case of plants, of the land and water resources it requires. (C) The area of one of the tracts is generally large enough to contain a representative sample of the organisms in the region. (D) There is little overlap between the list of tracts that are rich in species of butterflies and the list of those that are rich in species of birds. (E) The highest concentration of individuals of rare species is found where the general diversity of species is greatest.

单选题Grammarians have for years condemned as ungrammatical the English phrase "between you and I," insisting that the correct phrasing is "between you and me," with the objective case after a preposition. Such condemnations, however, are obviously unfounded, because Shakespeare himself, in The Merchant of Venice, wrote, "All debts are cleared between you and I." Which of the following, if true, most seriously weakens the argument above? (A) In his plays, Shakespeare intentionally had some of his characters use phrases he considered ungrammatical. (B) The phrase "between you and I" appears infrequently in Shakespeare's writings. (C) The more modern an English word or phrase, the less likely that modem grammarians will consider it acceptable for formal usage. (D) Many modern speakers of English sometimes say "between you and I" and sometimes say "between you and me." (E) Most native speakers of English who choose to say "between you and I" do so because they know that Shakespeare used that phrase.

单选题最新的研究表明，一些遗传类疾病，如先天性唇裂，大部分患者都出生在冬天，专家就此推测，是由于孕妇在孕后期食入的维生素含量不足，导致婴儿出现先天性疾病。因为在严寒的冬天，人们很难买到新鲜的蔬菜和水果，来补充维生素。 以下哪项如果为真，能支持题干中的专家的断言?

单选题A thorough search of Edgar Allan Poe's correspondence has turned up not a single letter in which be mentions his reputed morphine addiction.

Which of the following is assumed by the argument above?
