　　Nuclear radiation from power plant leaks and bomb tests resulted in millions of fewer baby girls born worldwide, according to a new study.

　　Scientists noted these types of atmospheric blasts rather than on-the-ground incidents like Chernobyl(切尔诺贝利), effected birth gender across the globe.

　　Scientists at Helmholtz Zentrum München, Germany, analysed population data from 1975 to 2007 for the U．S. and 39 European countries.

　　There was an increase in the number of baby boys relative to girls in all of the countries from 1964 to 1975. This was the case in many eastern European countries for several years after 1986.

　　Scientists are putting the first spike down to the atomic bomb tests of the 1960s and 1970s where radioactive atoms were blasted into the atmosphere. Air currents caught these atoms and then distributed them around the world.

　　They think the second spike is due to the 1986 Chernobyl disaster in which the reactor exploded in the Ukraine(乌克兰)．

　　The effects of Chernobyl were felt locally and no effect was seen in the U．S., probably because it was too far from the disaster to have an effect.

　　“The closer the country was to Chernobyl, the stronger the effect，” said study co-author Hagen Scherb, a biostatistician(生物统计学家) at the German Research Center for Environmental Health in Munich.

　　More males were born relative to females in Belarus—the Ukraine's neighbour—than in France.

　　The study is based largely on Cold War-era statistics, but the findings are highly relevant for how gender could be affected after future nuclear disasters.

　　And in the wake of Japan's Fukushima Daiichi nuclear power plant accident experts are predicting another baby boy boom could come, especially on the U．S. West Coast.

　　Previous radiation experiments on animals may give a clue for the increase in male births. Tests showed that radiation caused damage to the X chromosome(染色体) in sperm, Dr Scherb said.

　　A human sperm cell contains either an X or Y chromosome, while an egg only has an X chromosome. An XY combination will become a boy, while an XX combination will be a girl.

　　31．How many nuclear radiation accidents are mentioned in the passage?

　　A．1.B．2.C．3.D．4.

　　32．Which of the following is true according to the passage?

　　A．The on-the-ground incidents like Chernobyl, effected birth gender across the globe.

　　B．There was an increase in the number of baby boys in many eastern European countries for several years after 1986.

　　C．The Japan's nuclear accident will not effect the birth gender of the U．S. because of the long distance.

　　D．Where radioactive material has spread, women can't give birth to children.

　　33．How does radiation effect birth gender?

　　A．It damages the Y chromosome in sperm.

　　B．It stops X chromosomes and Y chromosomes combining.

　　C．It kills baby girls before they are born.

　　D．It damages the X chromosome in sperm.

　　34．What does the passage mainly tell us?

　　A．Nuclear age has led to millions of fewer baby girls being born.

　　B．Nuclear radiation has bad effects upon people's health.

　　C．Worries about radiation risks.

　　D．Nuclear age helps reduce the world population.

　?、?1.D　考查介词短语辨析。句意：我们想寻找一幢便宜些但要大些的房子的事终于有了结果。at an end结束，终止，完结；at the end of…在……末尾；in the end最后，最终，结果；on end竖立着，连续不断。句中有at last，故排除C项。

　　2．C　考查动词词义辨析。句意：听到她唯一的儿子在事故中丧生，老妇人顿时用手掩面而泣。bury one's face in one's hands双手掩面。

　　3．C　考查副词词义辨析。句意：由于供水线路老化和管理不善，该市浪费水的现象极为严重。extremely极其，非常；slightly轻微地；basically基本地；narrowly勉强地。

　　4．B　考查介词短语辨析。句意：为了纪念在大地震中为帮助挽救数以千计的人的生命而牺牲的英雄举办了这次晚会。in honor of…为了纪念……

　　5．C　考查动词词义辨析。句意：当今社会父母对孩子的呵护意识极强，他们试图想保护孩子们不受到任何真实的或虚幻的伤害。shelter此处用做动词，意为“?；ぃ踊ぁ薄pot弄脏，认出，发现，定位；dismiss开除，使解散；distinguish区别。

　　6．A　考查名词词义辨析。句意：这本书提供了一个简要的关于城堡历史的提纲和大厅里艺术藏品的详细介绍。outline概要，轮廓；give an outline of概要说明，描绘……的轮廓。

　　7．A　考查名词词义辨析。句意：那些头痛的人会发现这种药物能使头痛缓解。A符合句意，relief缓解，减轻，解除。 safety安全，保险；defense防御，防护；shelter掩蔽，?；?。

　　8．B　考查名词词义辨析。句意：他的突然发怒使会议不欢而散。burst在这里强调的是感情的突然释放或迸发。干扰项express作名词用时，意思是“快车，快递”，没有“表达”之意。

　　9．A　考查名词词义辨析。句意：现在，人们通常认为如果你考入一所重点大学，你就是父母的骄傲。pride骄傲；luck运气；value价值；cheer欢呼。

　?、?汶川地震发生后，来自世界150多个国家的驻华使节和国际组织代表陆续抵达外交部，在吊唁簿上签名留言，向中国政府和人民表示深切同情和诚挚慰问，对地震中的罹难者表示沉痛哀悼，还表达了他们对中国政府、军队以及中国人民对抗震救灾的支持。我驻外使馆也开展了一系列悼念活动。除了慰问外，国际组织还进行了捐款。

　　11．A　由上文的“a book of condolences(吊唁簿)”和下文的“the national mourning(全国哀悼)”可以看出，这里要表达的意思是：各国外交使节到外交部对地震中的罹难者表示沉痛哀悼。victim意思是“牺牲者，罹难者”。the wounded(受伤者)有很大的干扰性，但不符合上下文语境。

　　12．D　remain和形容词连用，意思是“保持某个状态”，强调继续停留于一处或保持原状态。而最大的干扰项是maintain “维持；保持；使继续”，但该词是及物动词，后面要加宾语。

　　13．C　conclusion用作名词，意思是“结束”。外交部举行的此次悼念活动将持续三天，直到全国哀悼日结束为止。如果不注意一词多义现象，忽略了conclusion还可以指“结束”，就很容易误选其他选项。

　　14．C　句意为：来自150多个国家和国际组织的大使及外交官……from意思是“来自……”。

　　15．B　150多个国家和国际组织的驻华使节排队在留言簿上签名，表达他们的哀悼之情。所以只有line up “排成行，排成列”符合语境。sign up “签约”； make up “编造”； stand up “起立”。

　　16．A　这里要表达的意思是，这些外交官员，向我们的遇难同胞低头致哀。bow one's head意思是“向……低头”。

　　17．D　support “支持，支援”。这些外交官还表达了他们对中国政府、军队以及中国人民处理灾难的支持。understanding(理解，了解)有很大的干扰性，但不符合他们积极捐款捐物支援我国灾区的事实，所以应该排除。

　　18．B　deal with在这里表示“处理，应对”。

　　19．C　the first to sign the book of condolences意思是“第一个在吊唁簿上签名留言，向中国政府和人民表示深切同情和诚挚慰问”的人。design “设计，策划”； resign “辞职”；sign “签名；在……签字”；respect “尊敬，尊重”。
