What can be inferred from the description of kakapo?
The word "haywire"(Paragraph 3) most probably means
选项
A、unexpected.
B、uncontrollable.
C、broken.
D、normal.
答案
B
解析
语义理解题。由题干中的haywire定位至第三段第四句,对语义的理解需要根据上下文语境及语义逻辑关系进行判断。本段就一项有关kakapo神秘之处的研究进行了说明。首先为了让kakapo数量增加,保护主义者给kakapo,特别是雌鸟喂食,这样雌鸟的体重就会超过繁殖需要的最低体重。这项工作进展得非常顺利。但是性别比例却went haywire。从此处的转折关系来看,这里与worked splendidly意思相反。接下来就这一现象进行了解释:83只鸟中有45只雄鸟,38只雌鸟,而且雌鸟所生后代中雄性数量是雌性数量的两倍。在最后一句中作者提到this biased sex ration。由此可见haywire与biased属于同一语义场,综合来看四个选项中uncontrollable含有"工作进展不顺,无法控制"之意,结果导致性别比例biased,故为答案。unexpected"出乎意料",虽然放回原句也符合前后句语境,但与末句中的biased sex ratio关联较小,既然是一项研究,研究人员就会进行人为控制,而uncontrollable是对producing twice as many sons as daughters状况的概括。unexpected则无此意,排除。broken不符合上下文语境,排除。normal与句首的but矛盾,如果情况正常,就不需要转折语气了。
