今天的句子：
Scientists have typically justified excluding female animals from experiments – even when studying conditions that are more likely to affect women – on the basis that fluctuating hormones would render the results uninterpretable. However, according to Rebecca Shansky, it is entirely unjustified by scientific evidence, which shows that the hormones and behaviour of male rodents are less stable than those of females.
思考题：
Why male animals are usually chosen as the study candidates?
(A) The hormones of male animals are more stable than that of females.
(B) Some conditions are more likely to affect women compared with men.
(C) The unstable hormones of women would affect the results of research.
(D) Excluding female animals from experiments is completely unjustified.
词汇突破：
1. justify 证明…合理
2. conditions 疾病（你不知道吧！）
3. on the basis 以…为基础，为依据
4. fluctuating 波动的，不稳定的
5. hormones 荷尔蒙，性激素
6. uninterpretable 无法解释
7. rodent啮齿类动物（老鼠）
句子解析:
主干：
it is entirely unjustified
其他：
1.However,
2.according to Rebecca Shansky,
3. by scientific evidence
4. which shows that
Which= scientific evidence
5.the hormones and behaviour of male rodents are less stable than those of females
参考译文：然而， Rebecca Shansky认为，科学证据证明这种说法是完全不合理的，这些证据表明雄性啮齿动物的激素和行为比雌性动物的激素和行为更不稳定。
改进一下：然而， Rebecca Shansky认为，有证据表明雄性啮齿动物的激素和行为比雌性动物的激素和行为更不稳定，所以上述做法是完全不合理的。
再看其他三个选项：
(B) Some conditions are more likely to affect women compared with men.
说的很对，但完全不构成原因嘛！排除！
(C) The unstable hormones of women would affect the results of research.
更是都偷换！是实验的雌性动物的不稳定荷尔蒙会影响实验结果，而不是女性的荷尔蒙！
排除！
(D) Excluding female animals from experiments is completely unjustified.
说的很对，但完全不构成原因嘛！排除！
怎么样，你就说像不像真题！！！！
