Gravitational pressure can cause blood to pool in the lower regions of the body, maki

14、ng it difficult to circulate blood to critical organs such as the brain. Terrestrial snakes, in particular, exhibit adaptations that aid in circulating blood against the force of gravity. The problem confronting terrestrial snakes is best illustrated by what happens to sea snakes when removed from t

15、heir supportive medium. Because the vertical pressure gradients within the blood vessels are counteracted by similar pressure gradients in the surrounding water, the distribution of blood throughout the body of sea snakes remains about the same regardless of their orientation in space, provided they

16、 remain in the ocean. When removed from the water and tilted at various angles with the head up, however, blood pressure at their midpoint drops significantly, and at brain level falls to zero. That many terrestrial snakes in similar spatial orientations do not experience this kind of circulatory fa

17、ilure suggests that certain adaptations enable them to regulate blood pressure more effectively in those orientations. One such adaptation is the closer proximity of the terrestrial snakes heart to its head, which helps to ensure circulation to the brain, regardless of the snakes orientation in spac

18、e. The heart of sea snakes can be located near the middle of the body, a position that minimizes the work entailed in circulating blood to both extremities. In arboreal snakes, however, which dwell in trees and often assume a vertical posture, the average distance from the heart to the head can be a

19、s little as 15 percent of overall body length. Such a location requires that blood circulated to the tail of the snake travel a greater distance back to the heart, a problem solved by another adaptation. When climbing, arboreal snakes often pause momentarily to wiggle their bodies, causing waves of

20、muscle contraction that advance from the lower torso to head. By compressing the veins and forcing blood forward, these contractions apparently improve the flow of venous blood returning to the heart. 文章概况:文章第一段开头说地球的重力对血液循环造成一定的影响,而结尾举了一个蛇的例子,说这种蛇有一种能力使得血液循环不受重力影响! 文章第二段拿sea snakes和第一段的 Terrestrial

21、 snakes进行类比,来说明 Terrestrial snakes确实有能力使血液循环不受重力影响! 文章第三段解释了一下 Terrestrial snakes这种蛇具有这种特殊能力的原因,这个原因和这种动物心脏的位置有关系.后面举了一些例子,涉及到了sea snake和arboreal snakes. Question #25. 147-01 (22404-!-item-!-188;#058&000147-01) The passage provides information in support of which of the following assertions? (A) The

22、 disadvantages of an adaptation to a particular feature of an environment often outweigh the advantages of such an adaptation. (B) An organisms reaction to being placed in an environment to which it is not well adapted can sometimes illustrate the problems that have been solved by the adaptations of

23、 organisms indigenous to that environment. (C) The effectiveness of an organisms adaptation to a particular feature of its environment can only be evaluated by examining the effectiveness with which organisms of other species have adapted to a similar feature of a different environment. (D) Organism

24、s of the same species that inhabit strikingly different environments will often adapt in remarkably similar ways to the few features of those environments that are common. (E) Different species of organisms living in the same environment will seldom adapt to features of that environment in the same

25、way. 问主旨,我们直接来看选项 A 说这种adaptation的缺点比优点还要多,没说,杀 B 说怎么适应环境,和文章有点联系,留着 C only出现,过于极端,主旨题目的正确答案如果出现极端化词汇就证明原文的作者是个疯子了 D 说一种动物适应环境的方式和适应其他环境的方式是类似的,文章没有这种比较,杀 E 住在相同环境的不同物种适应环境的方式是不同的,文章也没有出现过这种比较,杀 Question #26. 147-02 (22450-!-item-!-188;#058&000147-02) According to the passage, one reason that the di

27、ts blood vessels (C) the sea snake assumes a vertical posture less frequently than do the terrestrial and the arboreal snake (D) the sea snake often relies on waves of muscle contractions to help move blood from the torso to the head the force of pressure gradients in the water surrounding the sea s

28、nake exceeds that of vertical pressure gradients within its circulatory system 这个问题提示作用实在是太强了,问为什么sea snake放进水里 distribution of blood没变化的原因,答案要想正确至少得围绕什么谈过?必须跟水有点关系啊!我们来看选项 A 和水没关系,杀 B 和水有关系,留 C 和水没关系,杀 D 和水没关系,杀 E 和水有关系,留 B说的是压力对血管的影响,E说两种不同的压力哪个大,你问的是压力对distribution of blood的影响,选哪个?显然是B.这就是问题的作用,对

29、问题理解的比较精确,对原文的依赖就少. Question #27. 147-07 (22496-!-item-!-188;#058&000147-07) The author suggests that which of the following is a disadvantage that results from the location of a snakes heart in close proximity to its head? (A) A decrease in the efficiency with which the snake regulates the flow of
