题目内容

About a month ago I was present on a serious occasion where I heard the reading of a will. I can remember one passage that particularly struck me. It ran something (56) this. "And I direct that $ 10,000 be (57) to old William B, whom I have wished to help for many years, (58) always put off doing so." It (59) the last words of a dying man. But the story does not (60) there. When the lawyers came to (61) out the bequest (遗赠), they discovered that old William B had (62) , too, and so the (63) deed was lost. I felt rather (64) about that. It seemed to me a most regrettable. (65) that William should not have had his $10,000 just (66) somebody kept putting (67) giving it to him. And from (68) accounts, William could have done with the (69) . But I am sure (70) there are thousands of kindly little deeds waiting to be (71) today, which are being put off (72) later. George Herbert, in praise of good intentions, (73) that "One of these days is better than (74) of those days." But I say that (75) is better than all.

A. exciting
B. sorry
C. faithful
D. happy

Passage 2Questions 6 to 10 are based on the following passage: Human needs seem endless. (78) When a hungry man gets a meal, he begins to think about an overcoat, when a manager gets a new sports car, a big house and pleasure boats dance into view. The many needs of mankind might be regarded as making up several levels. When there is money enough to satisfy one level of needs, another level appears. The first and most basic level of needs involves food. Once this level is satisfied, the second level of needs, clothing and some sort of shelter, appears. By the end of World War II, these needs were satisfied for a great majority of Americans. Then a third level appeared. It included such items as automobiles and new houses. By 1957 or 1958 this third level of needs had fairly well been satisfied. Then, in the late 1950s, a fourth level of needs appeared: the "life-enriching" level. (79) While the other levels involve physical satisfaction, that is, the feed in comfort, safety, and transportation, this level stresses mental needs for recognition, achievement, and happiness. It ineludes a variety of goods and services, many of which could be called "luxury" items. Among them are vacation trips, the best medical and dental care, and recreation. Also included here are fancy goods and the latest styles in clothing. On the fourth level, a lot of money is spent on services, while on the first three levels more is spent on goods. Will consumers raise their sights to a fifth level of needs as their income increases, or will they continue to demand luxuries and personal services on the fourth level A fifth level would probably involve needs that can be achieved best by community action. Consumers may be spending more on taxes to pay for government action against disease, ignorance, crime, and prejudice. After filling our stomachs, our clothes closets, our garages, our teeth, and our minds, we now may seek to ensure the health, safety, and leisure to enjoy more fully the good things on the first four levels. Which of the following is NOT related to "physical satisfaction"

A successful career.
B. A comfortable home.
C. A good meal.
D. A family ear.

本部分着重考查考生对语言文字的理解和驾驭能力。这种能力包括:对词和句子一般意思和特定意义的理解;对比较复杂的概念和观点的准确理解;对语句隐含信息的合理推断;根据上下文,恰当选用词语;准确地辨明句意,筛选信息。注意:问题可能是选择一个词语或一个句子,使表达最为准确,也可能是考查对文字内容的理解,你的选择应与题目要求最相符合。(一) 大气中臭氧层的破坏。温室气体的增加,地球上生物多样性的减少,以及水土流失和污染的加剧都带来了严重的环境问题。保护环境,改良生态,控制气候变化是科学研究的前沿问题。全球变化,是指环境被破坏后对全球的影响。例如,温室气体的增加可以引起温度上升,会带来全球气候的变化。而地球上生物多样性的减少也是全球性的问题。前不久做过一个实验,在冰岛有很纯净的冰雪层,是若干年前积累起来的。在其中可以找到当时的气候资料,如大气的二氧化碳有多少,当时的温度是多少,从中可以看出15万年前到现在二氧化碳及温度的分布。这里有一张图片,可以看出宏观上二者大体相应的情况,说明温室气体的产生对全球气候有一定影响,但它们也不完全是对应的。最近,地球上的温度波动很厉害,二氧化碳一直在上升。但全球的温度也不是完全由二氧化碳所决定的。有很多因素有待现代科学家的研究。另外.从历史上看,自然也会影响二氧化碳的增加或减少。现在的变化是否完全是由于人为产生的温室气体,还需要进一步研究。值得注意的是,有人企图用这个来限制发展中国家能源增加,借此来抑制发展中国家的发展。这既是科学问题,可能也是政治上的问题。我们不能在科学尚没弄清之前,就轻易地作出结论。 下列说法符合原文意思的一组是( ) ①二氧化碳是温室气体,②地球温度指的就是全球气候,③全球气候变化是全球变化的一个方面,④温室气体增加可造成环境破坏,⑤二氧化碳的增加是由能源增加引起的

A. ①④⑤
B. ②③④
C. ②③⑤
D. ①③④

(六) 1个细菌经过20分钟左右就可以一分为二;1根葡萄枝切成10段就可能变成10株葡萄苗;1株草莓依靠它沿地“爬走”的匍匐茎,1年内就长出数百株草莓苗……凡此种种,都是生物靠自身的一分为二或一小部分扩大来繁衍后代,这就是无性繁殖。无性繁殖的英文名称叫Clone,译音为“克隆”,其含义已不仅指无性繁殖,也包括无性繁殖系。凡是来自一个祖先的无性繁殖的一群个体叫无性繁殖系,简称无性系。 自然界的许多动物,在正常情况下都是依靠父方产生的雄性性细胞(精子)与母方产生的雌性性细胞(卵子)融合(受精)成受精卵(合子),再由受精细胞经过一系列细胞分裂长成胚胎,最终形成新的个体,这种依靠父母双方提供性细胞,并经两性细胞融合生产后代的繁殖方法叫有性繁殖。但是,如果我们用外科手术将1个胚胎分割成2块、4块、8块……最后通过特殊的方法使1个胚胎长成2个、4个、8个……生物体,这些生物体就是克隆个体,而这一群个体就叫做无性繁殖系。 克隆羊“多利”就是这样被“创造”出来的。英国爱丁堡罗斯林研究所的威尔莫特等人先给“苏格兰黑面羊”注射促性腺素,促使它排卵后,用板细的吸管从卵细胞中取出核。与此同时,从怀孕3个月的“芬多席特”6龄母羊的乳腺细胞中取出核,将它注入“苏格兰黑面羊”的卵细胞中。手术完成后,用相同频率的电脉冲刺激换核卵,让“苏格兰黑面羊”卵细胞质与“芬多席特”母羊乳腺细胞的核相互协调。使这个“组装”细胞在试管里经历受精卵那样的分裂、发育而形成胚胎的过程。然后,将胚胎巧妙地植入另一只母羊的子宫里。经过一段时间后,这只“护理”体外形成胚胎的母羊产下了小绵羊“多利”。“多利”不是由母羊的卵细胞和公羊的精细胞受精的产物,而是“换核卵”一步步发展的结果。 克隆羊的诞生在世界各国引起了震惊,原因在于卵细胞中换进去的是体细胞的核,而不是胚胎细胞核。这个结果证明:动物体中执行特殊功能、具有特定形态的所谓高度分化的细胞与受精卵一样具有发育成完整个体的潜在能力。也就是说,动物细胞与植物细胞一样,也具有全能性。 下列对“克隆”的含义理解不正确的一项是( )

A. 动植物通过无性繁殖而扩大繁衍后代
B. 来自同一个祖先的无性繁殖的个体
C. 用人工的方法将生物胚胎融合而产生的后代
D. 动植物“无性繁殖”和“无性繁殖系”的总称
