原文:
Passage 13
Biologists have long debated about whether egg production in birds is biologically highly costly,some theorizing that egg production is energetically or nutritionally demanding. Lack, however,suggested that clutch size—the number of eggs a bird lays per breeding cycle—is far below the potential limit of egg production. He suggested that clutch size had instead evolved in relation to the number of young that the parents could successfully rear. Subsequently, most studies focused on limitations operating during chick rearing, particularly among altricial species (species in which the parents feed their young in the nest). Lack later recognized that in precocial species (species in which young feed themselves), clutch size might be explained by different factors—the availability of food for egg-laying females, for example.

问题是:Consider each of the choices separately and select all that apply.
2. The passage suggests that Lack would agree with which of the following statements about
factors affecting clutch size in birds?
A. In altricial species, clutch size is determined primarily by factors operating after eggs are laid.
B. In precocial species, clutch size is determined primarily by factors operating after eggs are laid.
C 是对的, 就不给啦。

我感觉 A 和B 都不对呀。我理解是 altricial 这个种类,比如 potential 是 10个eggs, 但是 由于只能养活5个, 那肯定就 lay 5个了 。 我理解对吗?

我理解是 altricial 是 能养活多少 就 多少的 clutch size。  

precocial 是 能有多少 food 就多少 的clutch size

Hi~~kaoXX网站是一个比较无良的网站,盗取各种地方的资料,包括这个88题,是目前所谓的真题70篇+OG汇总的,所以建议不在论坛里提到这个无良网站的名字哈~~

你的理解是对的,问题的关键在于“能养活几个”到底算不算是“factors operating after eggs are laid”。虽然说“能养活几个”确实取决于蛋生下来之后的环境,但比较纠结的点在于,parents在产这些蛋之前显然是不可能知道这些情况的,所以它们的决定实际取决于对蛋生下来后环境的“估计”,而这个“估计”,又显然是在蛋生下之前发生的了。

不过看到原文后面一句话,你就知道这道题是怎么回事了:
Subsequently, most studies focused on limitations operating during chick rearing, particularly among altricial species (species in which the parents feed their young in the nest).

和factors operating after eggs are laid完全对应,A选项就是从这句话里出出来的。

总体而言,我觉得这个题目出得不是很好,尤其是选项里的determined by非常容易引起歧义,建议以理解文章为主,不必太过在意答案。顺便重申一下我的观点,有时间做这些所谓的真题,不如好好把150和OG再仔细做一遍。

是啊,这件事情我去年大概就知道了。 很多原创的资料都不是KXX的。 所以当时就觉得 GRE的市场很乱。但是也不知道怎么说, YouD,微Chen ,什么维C。。 我作为一个 备考者,暂时不想去计较太多了。如果我有幸 这一次通过了。 我也打算来寄托 写点感悟。

好的,谢谢,OG 的阅读做完啦。 150太难, 本来打算做陈虎平的,想想没多少时间了,就做做真题看看,抱着侥幸心理,在练习的同时,万一考场还能遇到,会给填空带来更多的时间。
