问大家一道机经阅读，鱼的social learning

vicipeteUID: 3363516

Although social learning(通过模仿其它个体的行为来学会某种行为) is well documented among fish, few studies have investigated social learning within a developmental context in these taxa. Rather than investigating the development of a particular skill, Chapman, Ward, and Krause investigated the role of group density during development in later foraging success in laboratory-housed guppies. When raised with a small number of conspecifics(同种生物), guppies were quicker to locate food by following a trained adult guppy than were guppies raised in large groups. This counterintuitive finding is explained by the fact that guppies reared in the low-density(网上的版本是high-density，不过听XDF老师说是low-density) condition were less likely to shoal(与群体一起游动) with others and, therefore, were less likely to learn the benefits of social learning. Instead, fish reared in high-density situations may learn that conspecifics are to be viewed as competitors, rather than as potential sources of adaptive information. This finding suggests that at least for guppies, the early social environment may have an effect on the capacity for social learning, if not on the socially learned behaviors themselves.

这篇阅读读乱了。。。
首先，不知道开始时chapman例子中描述的‘guppies were quicker...’到底与后文的low-density、high-density对应？
是不是guppies in high-density说的就是Chapman例子中‘guppies were quicker to locate food by following a trained adult guppy than were guppies raised in large groups.’？？？而low-density对应a large groups？？？

如果Chapman的例子说的是high-density，那么‘Instead, fish reared in high-density situations may learn that conspecifics are to be viewed as competitors, rather than as potential sources of adaptive information.‘怎么翻译？？？我感觉’rather than as potential sources of adaptive information.‘也是在说fish in high-density的social learning低。。。。

还有instead在这里是表示对比关系吧？？？

请大神们帮帮忙，现在很困惑。。。

我怎么感觉网上的版本high-density是对的。。。。

AnEscapistUID: 3546519

又想了一下，还是应该是low-density， 这文章好像说的是low-density和high-density的social learning能力都低，所以最后一句说影响的是capacity for social learning，而不是socially learned behaviors themselves。  也不知道我的理解对不对，楼主酌情考虑。
PS:红色确实不太友好，看的眼睛疼。。。

昨天想了半天还是感觉应该high-density，如果这样那么instead应该表示递进。。。

这道题里貌似instead表示不是对比。。。
The journalism professor’s first lecture tackled (i) ______ itself, challenging the journalistic trope that an article has to represent all sides—no matter how marginal—equally. Instead, the professor argued that this impulse to (ii) ______ even obviously (iii) ______ views in order to furnish opposing perspectives is harmful to basic accuracy.
Blank (i)                                Blank (ii)                                      Blank (iii)
(A) marketability                     (D) approve                               (G) controversial
(B) objectivity                        (E) present                                (H) fringe
(C) partisanship                     (F) denigrate                               (I) straightforward
答案是BEH。

说影响capacity for social learning，不就是应该说明一个好一个差嘛。。。

instead表示递进带到原文中，好像是更加通顺。以前没见过这种用法，应该是我理解错了。high-density然后instead进一步解释high-density的capacity for social learning 比较弱，更加解释了This counterintuitive finding。  PS：如果考试遇到，见机行事！

主要是之前见过那道pp2的题，其实我也不知把instead作为递进理解对不对，查了vocabulary.com就两个含义：in place of, or as an alternative to；on the contrary。但是现在只能这样最顺了，先这样吧。。。。。。。

谢谢你

这里instead还是instead本意  但是不取反是否是因为thisXX/thatXX, 如果出现指代（this impulse= represent all sides—no matter how marginal—equally），直接找前文对应。就和similar一个道理？
extrapolate！
