　　25 Although these molecules allow radiation at visible wavelengths, where most of the energy of sunlight is concentrated, to pass through, they absorb some of the longer-wavelength, infrared emissions radiated from the earth’s surface，radiation that would otherwise be transmitted back into space.

　　虽然这些分子允许可见波长(visible wavelength)的辐射——阳光的绝大部分能量就汇集于此——不受阻挡地穿透，但它们却会吸收Ḁ些较长波长(longer-wavelength)，亦即从地球表面辐射出的红外发射(infrared emission)，这种辐射若不是二氧化碳的缘故就会被重新输送回太空。

　　26 The role those anthropologists ascribe to evolution is not of dictating the details of human behavior but one of imposing constraints—ways of feeling, thinking, and acting that "come naturally" in archetypal situations in any culture.

　　这些人类学家所归诸于生物进化的作用，不是规定人类行为的种种细节，而是将各种限制强加于人类——即在任何文化的典型情景中都会“自然表露”的情感、思维、以及行动方式。

　　27 which of the following most probably provides an appropriate analogy from human morphology for the “details” versus “constraints”distinction made in the passage in relation to human behavior?

　　以下哪一个选项最有可能为文章中所谈到的与人类行为有关的“人类行为细节”相对“人类所受限制”之间的差异，从人类形态的角度上ᨀ供了一个合适的类比?

　　28 A low number of algal cells in the presence of a high number of grazers suggested，but did not prove, that the grazers had removed most of the algae.

　　在存在大量食草动物的同时却只有少量的水藻花粉囊，这暗示出——但没能证明——食草动物已吞噬了大部分水藻。

　　29 Perhaps the fact many of these first studies considered only algae of a size that could be collected in a net (net phytoplankton), a practice that overlooked the smaller phytoplankton (nannoplankton) that we now know grazers are most likely to feed on, led to a de-emphasis of the role of grazers in subsequent research.

　　可能这样一个事实，那就是很多这样的最初的研究只是考虑了那些能够用网捞起来的大小的水藻，这样一个忽视了更小的浮游生物(而这些浮游生物我们现在知道是捕食者主要的食物)的做法，导致了在接下来的研究中对于捕食者的作用的贬低。

　　30 Studies by Hargrave and Geen estimated natural community grazing rates by measuring feeding rates of individual zooplankton species in the laboratory and then computing community grazing rates for field conditions using the known population density of grazers.

　　由哈格雷夫(Hargrave)和吉恩(Geen)所进行的研究，对自然条件下的群落捕食速率进行了估计，其手段是通过测量出实验室内单独的浮游动物种类的捕食速率，然后利用已知的食草动物种群密度，计算出实地状况下的群落捕食速率。
