35. The historian Frederick J. Turner wrote in the 1890's that the agrarian discontent that had been developing steadily in the United States since about 1870 had been precipitated by the closing of the internal frontier——that is，the depletion of available new land needed for further expansion of the American farming system. 史学家弗雷德里克.杰.特纳（Frederick J.Turner）于十九世纪九十年代著述道，美国约自18世纪70年代以来一直在持续不断发展的农民不满，由于国内边远地区（internal frontier）的封闭而更趋加剧——亦即是说，美国农业系统进一步扩展所必需的可资利用的新土地几近耗竭。
36. In the early 1950's，historians who studied preindustrial Europe （which we may define here as Europe in the period from roughly 1300 to 1800） began， for the first time in large numbers，to investigate more of the preindustrial European population than the 2 or 3 percent who comprised the political and social elite：the kings，generals，judges，nobles，bishops，and local magnates who had hitherto usually filled history books. 二十世纪五十年代早期，研究前工业化时代欧洲（此处我们可将其界定为约自1300年至1800年这一时期的欧洲）的史学家，首次以众多的人数（杨鹏的书中：第一次以大量的数据），开始调查前工业化时代欧洲人口中的大多数，而非那些构成了政治与社会精英阶层的百分之二或三的人口，即国王、将军、法官、贵族、主教、以及地方上的达官显贵，而正是这部分人一直到那时为止普遍充斥于史学著作。
37. Historians such as Le Roy Ladurie have used the documents to extract case histories， which have illuminated the attitudes of different social groups （these attitudes include，but are not confined to，attitudes toward crime and the law）and have revealed how the authorities administered justice. 象勒罗伊。拉迪里（Le Roy Ladurie）一类的史学家利用这些文献史料从中挖掘出某些个案史（case history）来，阐明了不同社会群体的态度（这些态度包括，但并非局限于，对犯罪和法律的态度），并揭示出当局是如何执行审判的。
38. It can be inferred from the passage that a historian who wished to compare crime rates per thousand in a European city in one decade of the fifteenth century with crime rates in another decade of that century would probably be most aided by better information about which of the following? 从文章中可以推断出来，一个希望比较十五世纪以前一个十年的某个欧洲城市中的每千人的犯罪率与另外一个十年中的犯罪率的历史学家将会被以下那种信息的提高所最好的帮助？
39. My point is that its central consciousness-its profound understanding of class and gender as shaping influences on people's lives-owes much to that earlier literary heritage，a heritage that，in general，has not been sufficiently valued by most contemporary literary critics. 我的论点是，其作品的中心意识——它将阶级和性别作为人们生活的决定性影响而作出的深邃理解——在很大程度上借鉴了那个早期的文学遗产，而这一遗产就总体而言还尚未获得大多数当代文学评论家的足够重视。
40. Even the requirement that biomaterials processed from these materials be nontoxic to host tissue can be met by techniques derived from studying the reactions of tissue cultures to biomaterials or from short-term implants. 即使是这样的要求，即从这些材料中加工出来的生物材料应该对受移植者的组织无害，也能够通过从研究组织培养对生物材料的反应而来的，或从研究短期移植而来的技术来满足。

61. There have been attempts to explain these taboos in terms of inappropriate social relationships either between those who are involved and those who are not simultaneously involved in the satisfaction of a bodily need，or between those already satiated and those who appear to be shamelessly gorging. 人们试图对这些禁忌作出解释，所依据的要么是那些正置身于某一身体需要满足的人与那些并置身于某一身体需要之满足的人之间的，要么是那些早已酒足饭饱的人与那些正在不知羞耻地狼吞虎咽失之间的不相称的社会关系。
62. Many critics of Family Bronte's novel Wuthering Heights see its second part as a counterpoint that comments on，if it does not reverse，the first part，where a "romantic" reading receives more confirmation. 研究艾米丽。勃朗特（Emily Bronte）小说《呼啸山庄》（Wuthering Heights）的许多文学评论家，将小说的第二部分视作一种对比物，即使没有将第一部分予以逆转的话，也是在对第一部分作出一种诠释评判，而在小说第一部分中，一种"浪漫的"的读解能获得更为充分的确证。
63. Granted that the presence of these elements need not argue an authorial awareness of novelistic construction comparable to that of Henry James， their presence does（15） encourage attempts to unify the novel's heterogeneous parts. 诚然，这些因素的存在并不能证明作者对小说架构的意识可与亨利。詹姆斯（Henry James）的那种意识相比拟；然则，任何力图将小说所有形形色色的因素统一起来的做法，在某种程度上注定是无法令人信服的。 Granted that:大家都统一、当然，表让步，=admitted , of course.
64. This is not because such an interpretation necessarily stiffens into a thesis（although rigidity in any interpretation of this or of any novel is always a danger），but because Wuthering Heights has recalcitrant elements of undeniable power that，ultimately，resist inclusion in an all-encompassing interpretation. 这倒不是因为这样的一种解释必定会僵化成为一个命题（尽管对这部或任何一部小说的解释中，僵化死板总是一种危险），而是因为《呼啸山庄》拥有一些极难驾御的因素，以其无可辩驳的力度，最终拒绝被囿于一个囊括无遗的解释中。
65. The isotopic composition of lead often varies from one source of common copper ore to another，with variations exceeding the measurement error；and preliminary studies indicate virtually uniform is topic composition of the lead from a single copper-ore source. 铅的同位素构成经常在一种普通铜矿石来源与另一种铜矿石来源之间存在差异，其差异程度超出测量误差；而最初的研究表明，对于来自单独一个铜矿石来源的铅来说，其同位素构成几乎是毫无二致的。
66. More probable is bird transport，either externally，by accidental attachment of the seeds to feathers，or internally，by the swallowing of fruit and subsequent excretion of the seeds. 更有可能的是鸟类运输：或者是通过外部途径，即由于种籽偶然粘附在羽毛上；或者是通过内部方式，即由于鸟类吞食果子并随后将种籽排泄出来。
67. A long-held view of the history of English colonies that became the United States has been that England's policy toward these colonies before 1763 was dictated by commercial interests and that a change to a more imperial policy , dominated by expansionist militarist objectives , generated the tensions that ultimately led to the American Revolution . 一个对于后来成了美国的英国殖民地的历史的长久以来的观点，认为英国在1763年以前对于这些殖民地的政策被经济利益所支配，而且认为一种向着更大程度帝国制度的政策上的转变——为扩张主义的军事目标所左右——产生了最终导致美国革命的紧张气氛。
