　　76. A very specialized feeding adaptation in zooplankton is that of the tadpolelike appendicularian who lives in a walnut-sized （or smaller） balloon of mucus equipped with filters that capture and concentrate phytoplankton. 浮游动物体内一种极特殊的进食适应性变化是蝌蚪状的尾海鞘纲动物（appendicularian）的那种适应性变化，而尾海鞘纲动物则存活于核桃大小（或更小）的黏液球囊内，装备有过滤器，用以捕捉和集中浮游植物。

　　77. These historians，however，have analyzed less fully the development of specifically feminist ideas and activities during the same period. 但是，这些史学家还不曾充分地分析同一时期中那些具体的女权主义思想和活动的发展。

　　78. Apparently most massive stars manage to lose sufficient material that their masses drop below the critical value of 1.4 M before they exhaust their nuclear fuel. 显然，大多数的巨星能够失去足够多的物质以至于在燃尽其核燃料以前他们的质量下降到关键值1.4M以下。难在：sufficient ……that…… = so much （many ） …… that……

　　80. An impact （on the Mars） capable of ejecting a fragment of the Martian surface into an Earth-intersecting orbit is even less probable than such an event on the Moon, in view of the Moon's smaller size and closer proximity to Earth. 一个能够把活性表面的碎片射入地球交叉轨道的碰撞发生的可能性甚至小于这种事件在月亮上发生的可能性，考虑到月亮更小的尺寸及其与地球接近的程度。

　　81. Not only are liver transplants never rejected，but they even induce a state of donor-specific unresponsiveness in which subsequent transplants of other organs, such as skin,from that donor are accepted permanently. 但是，我们已经发现，在许多种老鼠之间，这些移植法的"常规"并没有被肝脏移植物所遵循。肝脏移植物非但从没遭到过排斥，甚至还诱发了一种供者特异性无应答状态（donor-specific unresponsiveness），在此状态中，随后来自那个供者其它器官的移植物，如皮肤，会永久地被接受。

　　82. As rock interface are crossed, the elastic characteristics encountered （by seismic waves）generally change abruptly, which causes part of the energy to be reflected back to the surface, where it is recorded by seismic instruments. 当岩石界面被穿过的时候，震波所遇到的弹性性质通常会发生突然的变化，这就使得一部分能量被反射回地面，在地面反射回来的波被震波纪录仪记录下来。

　　83. While the new doctrine seems almost certainly correct，the one papyrus fragment raises the specter that another may be unearthed，showing，for instance，that it was a posthumous production of the Danaid tetralogy which bested Sophocles,and throwing the date once more into utter confusion. 数据资料已被统计出来，或被重新统计出来，以便证明在文体学这方面，《乞援衰女》实际上确实在《波斯人》和《七雄攻忒拜》（后两者现在则变成了"原始"的剧作）之后以及在轴残片却唤起了一种幽灵似的疑虑，即另一块残片有可能再度被挖掘出来，并证明，比如说，《乞援衰女》是作者藉以击败索福克勒斯的《达那特四部曲》的一部死后出版之作，从而将创作年代再度置于极度的混乱之中. 注：best:击败,=defeat, overcome, outdo

　　84. The methods that a community devises to perpetuate itself come into being to preserve aspects of the cultural legacy that that community perceives as essential. 一个社会所创造出来藉以使其自身生生不息、恒久不衰的方法得以形成产生，以保存在这个社会看来具有本质意义的文化遗产的各个方面。

　　85. Traditionally, pollination by wind has been viewed as a reproductive process marked by random events in which the vagaries of the wind are compensated for by the generation of vast quantities of pollen, so that the ultimate production of new seeds is assured at the expense of producing much more pollen than is actually used. 传统上，风媒传粉被看成是这样的繁殖过程：其特征就是由一些随即事件的发生，在这些随机事件里，风的反复无常被大量的产生花粉所补偿，以至于新种子的最终产生被保证了，其代价是产生远远多于实际使用量的花粉。

　　86. Because the potential hazards pollen grains are subject to as they are transported over long distances are enormous，wind pollinated plants have，in the view above，compensated for the ensuing loss of pollen through happenstance by virtue of producing an amount of pollen that is one to three orders of magnitude greater than the amount produced by species pollinated by insects. 由于花粉粒在其长距离的运输过程中所要面临的潜在危险是巨大的，按上述观点来看，由风授粉的植物补偿了通过偶发事件而伴随造成的花粉损失。其途径是，制造出大于昆虫授粉的植物种类所产生的花粉量的一至三个数量级的花粉量。
