Finally, they may be dietary specialists, but their abundance may be chronically low relative to the availability of flowers.第二段最后一句话，反着说，和选项b相同。定位后寻找总结性句子，然后找相应选项

设（F2-F1）／F1=50/F1条件一单独不行；
只知道总体的增长率也不知道F的增长率啊，条件2单独也不行；
条件一和条件二一起也不行。 （F2-F1）+（P2-P1）=0.05A， 你不知道P1和P2的变化，也不知道A为多少就肯定不知道F的增长率啊

the average distance from the heart to the head can be as little as 15 percent of overall body length.原文只提了心脏位置的问题，所以选b。c选项中的水蛇尾巴和陆地蛇尾巴供血上有什么区别没有提。

只看这一句的围观作用，不要考虑整个这个事的作用。

这不应该是果因推理吗？

That many terrestrial snakes in similar spatial orientations do not experience this kind of circulatory failure suggests that certain adaptations enable them to regulate blood pressure more effectively in those orientations.第二段最后一句。之后第三段写了one adaption，and another adaption

1-根据定语从句就近修饰的原则，the number of which修饰的是recovery area，显然跑偏了意思，AD排除；
2-E，是个when引导的时间状语从句，变成scheduled to take over发生的时间条件，句意不对；排除；
3-剩下BC，关键点是however不是连词，是副词，不能连接两个完整的句子，只能是B对了

为什么和陶瓷不能并列呢？

所有选项有个split点，immune from /to：
immune from ： 免于，免于 claims，taxation等；
immune to： 对..免疫；
这题里面显然应该用后者，排除ABD；在C和E里面选，C的时态有问题，所以选E；
不知道 immune from/to的这个差别，错了：（。。。

觉得有点像因果推理

老师求更新，表是啥

二杀错。又选了c。 choice c: 'the 35 years since' implies that the present is 35 years after the release date. not only does this conflict with the meaning of the original, but it also renders the past perfect (from the underlined part) inappropriate: you'd need present perfect in this case. also, since the release is a point event, it would belong in the simple past.

为什么是is而不是was呢

未能理解排除A、B、E的理由。
请问，A，E选项中的 that which they would normally eat、B选项中的what they would normally eat，
分别与 a diet that they would normally eat 有什么不同呢？

我也错选了C--现在我在想，是不是如果把C 选项中的removing改成removal,就说的通了？ C是错在名词结构不对称:the removal应该对应the clearning就没问题了.

问题问的是the difference in the amount of cratering。第二段陈述了是因为geological activity的程度， Io is extremely geologically active, Europa seems to be active on a more modest scale, and Ganymede has undergone bouts of activity in its geological past. Only Callisto reveals no geological activity.

is related more positively to post acquisition success than retaining lower-ranked top executives.原文中说高级管理者比低级管理者和后期收购成功更相关，c选项是反着说：对于后期收购成功来说，低级管理者不如高级管理者重要。

Although from the UEP position it seems sensible to retain less tenured executives and allow more tenured ones to leave, such a strategy appears to lower the probability of acquisition success.作者不同意UEP的观点，就是双方会disagree的

Bergh conducted a study of executive retention and acquisition outcome第二段开头句B做的，就是前面research limited的。

为什么“水乳胶球”和“陶瓷器“不能并列呢？画作的最终呈现的物品是陶瓷器啊，而且这个陶瓷器也有关于画作的定语。
