标题: 求救！！prep-1-64 问题有点儿没看懂！谢谢！！ [打印本页] 作者: beryl8 时间: 2010-9-3 22:04 标题: 求救！！prep-1-64 问题有点儿没看懂！谢谢！！ Adult female rats who have never before encountered rat pups will start to show maternal behaviors after being confined with a pup for about seven days. This period can be considerably shortened by disabling the female's sense of smell or by removing the scent-producing glands of the pup.
Which of the following hypotheses best explains the contrast described above?
(A) The sense of smell in adult female rats is more acute than that in rat pups. (B) The amount of scent produced by rat pups increases when they are in the presence of a female rat that did not bear them. (C) Female rats that have given birth are more affected by olfactory cues than are female rats that have never given birth. (D) A female rat that has given birth shows maternal behavior toward rat pups that she did not bear more quickly than does a female rat that has never given birth. (E) The development of a female rat's maternal interest in a rat pup that she did not bear is inhibited by the odor of the pup.
请问该题问题Which of the following hypotheses best explains the contrast described above就是说哪一个与原文段说法相反是吗？？实战中会碰到这么问法吗？作者: shirly813 时间: 2010-9-4 00:56
答案是否是(E)呢 估計你對contrast的意思並沒有搞懂,文中實際上問的是: 以下哪一個假設可以最有效的解釋以上兩者的對比呢? 所謂以上兩者的對比是: 通常情況下,沒有生育過的母鼠要在與幼鼠共處7天後才會展現母性/然而可以經過阻斷母鼠嗅覺與停止幼鼠分泌體味來加速母鼠展現母性作者: shirly813 时间: 2010-9-4 00:57
