题目请参考

CASK EFFECT0910G阅读全方位锻炼--难度【LSAT1-7


题目分析
14(D)
定位原文首段
Three basic adaptive responses—regulatory, acclimatory, and developmental—may occur in organisms as they react to changing environmental conditions.
Regulatory responses…Acclimation involves…Developmental responses, however…”以及大篇幅的water bugs可以看出,
discuss three different types of adaptive responses and provide an example that explains how one of those types of responses works

15(D)
根据题干
a pond… were to dry up in June
定位原文
The summer (early) generation, in contrast, is usually dimorphic—some individuals have normal functional (macropterous) wings; others have much-reduced (micropterous) wings of no use for flight”这里说明在summer有两种情况发生

But small ponds occasionally dry up during the summer, forcing the water bugs to search for new habitats, an eventuality that macropterous individuals are well adapted to meet
本句but与“no use for fully developed wings“形成转折,表明夏天的wings在某些环境变化下还是有用的dry。换言之,这里的”adapted to meet”就是说,macropterous可以具备飞行条件而得以生存,但micropterous则不能。

选项(D)中的some individuals就是指macropterous

因此,选项(D)为最佳选项
从本题可以看出,but所在句群可能是出题点

16(A)
定位原文
Eggs laid by the overwintering adults in the spring, which develop into the summer generation of adults, are formed in early autumn and early spring. Those eggs formed in autumn are exposed to cold winter temperatures, and thus produce micropterous adults in the summer generation. Those formed during the spring are never exposed to cold temperatures, and thus yield individuals with normal wing
如上题所述,water bugssummer有两种情况
Winter--气温低—micropterous
Spring--气温高—macropterous

因此,如果“the winter months of a particular year were unusually warm”,那么micro-将减少,macro-将增加,即
eggs formed by water bugs in the autumn would probably produce a higher than usual proportion of macropterous individuals; K:

17(A)
结合16/15题的原文定位信息,比较容易作答本题
the overwintering generation forms two sets of eggs, one exposed to the colder temperatures of winter and one exposed only to the warmer temperatures of spring

18(B)
根据“an example of a regulatory response”定位原文于
Regulatory responses involve rapid changes in the organism’s use of its physiological apparatus—increasing or decreasing the rates of various processes, for example
抓取关键词rates,与选项(B)的关键词相符合
再结合排除法
(A)(C)均为“Acclimation involves morphological change—thickening of fur or red blood cell proliferation—which alters physiology itself

(D)为“In all three, adjustment of biological features (morphological adjustment)
(E)为第三种

19(E)
定位原文
The eggs laid in the summer hatch and develop into adults in late summer. They live over the winter before breeding in early spring. Individuals in the second (overwintering) generation have fully developed wings
以及
Eggs maintained in a warm environment always produce bugs with normal wing, but exposure to cold produces micropterous individuals. Eggs producing the overwintering brood are all formed during the late summer’s warm temperatures.
可以确定
contain a much greater proportion of macropterous water bugs than the early spring-hatched generation

20(C)
定位原文
Adult water bugs of the overwintering generation brought into the laboratory during the cold months and kept warm, produce only macropterous offspring
正常情况应该如下
Eggs laid by the overwintering adults in the spring, which develop into the summer generation of adults, are formed in early autumn and early spring. Those eggs formed in autumn are exposed to cold winter temperatures, and thus produce micropterous adults in the summer generation.
但现在却是“produce only macropterous offspring”,变化的因素就在于
cold monthsàkept warm
即,温度的变化对eggs的影响
the effect of temperature on developing water-bug eggs

21(A)
通过前面几题的分析,相信我们对作者的思路已经把握得比较清楚了
Biological phenomena are presented, examples of their occurrence are compared and contrasted, and one particular example is illustrated in detail.
