【正确答案】
B
【答案解析】动词辨析题。句意为:长期以来,人们一直认为大量饮酒会给妈妈和其未出世的孩子带来麻烦。句子是be+过去分词+with的结构。be linked with “与……有关”,即大量饮酒与麻烦有关,或者造成了问题,符合句意。related不与with搭配,故排除;deal“处理”为不及物动词,不能用于被动句,因此排除;integrate“使成一体,使合并”,不符合句意,故排除。
【答案解析】名词辨析题。句意同上。显然,这一研究的课题是少量饮酒对孕妇及其孩子造成的影响,选项用于修饰drink“(酒)的一杯”,因此选择表示数量最少的a couple of“两三(杯)”。a dozen of“十几(杯)”,a lot of“很多(杯)”和a score of“二十(杯)”均不符合文意,故排除。
【正确答案】
C
【答案解析】同定搭配题。句意为:研究做得十分彻底,结果不容置疑,因此它应该给这一领域的研究划上一个句号。通过分析句子结构可以看出,its findings(were)______conclusive与The study…was so well done为并列关系,与其后的that构成了so…that…的结构,因此选择so。
【答案解析】句子结构题。句意为:……这为对不同的饮酒量对孩子出生后造成的影响的研究提供了不受人为干预的 实验。结合上下文可以看出,整个句子的主句为Approximately a third of pregnant women report drinking at least some alcohol,而句子的后半部分为伴随状语,因此选择现在分词offering。
【答案解析】动词辨析题。句意为:当婴儿九个月大时,研究人员要求妈妈们描述她们在怀孕期的饮酒量。分析句子结构可知,they had ______ during pregnancy是修饰alcohol的定语从句,从句省略了的关系代词that/which作选项动词的宾语。所以选择consumed“消耗,喝光”,这里可表示“喝(酒)”。assumed“承担,以为,采用”,resumed“继续,恢复”和exhausted“用完,耗尽”均不符合句意,故排除。
【答案解析】介词辨析题。句意同上。由文章倒数第三段最后一句The kids took similar tests at age three and again at age five可知,接受研究的孩子年龄最大的为五岁,因此研究的对象是三岁或五岁的孩子。由此判断答案为through“从头到尾,通过”。before“在……之前”和since“自……以来”表示的时间关系与文意不符,排除;beneath“在……下面”表示方位,不符合语境,故排除。
