其实出题者也并没有要求读者把这些内容搞清，只需知道前面那句话是一个判断句，说犹太法和伊斯兰法一致，后面这句话是对上面一句话的解释，因此肯定也在说它一致。再看第二句话的结构，上来就是一个用though表示的让步语气，我们可以看出在一个break between，那么逗号后就应该是省略了but的转折语气，该说没有break between，果然我们看到了very close to 的字样。我们也知道，既有让步又有转折时，作者强调转折之后的内容。所以这句话仍是在说犹太法一致。
043 Both Jewish law and canon law are more uniform than Islamic law(这是作者加的便于理解的话). Though historically there is a discernible break between Jewish law of the sovereign state of ancient Israel and of the Diaspora(the dispersion of Jewish people after the conquest of Israel), the spirit of the legal matter in later parts of the Old Testament is very close to that of the Talmud, one of the primary codifications of Jewish law in the Diaspora.
44. Islam，on the other hand，represented a radical breakaway from the Arab paganism that preceded it;Islamic law is the result of an examination,from a religious angle，(examination)of legal subject matter that was far from uniform，comprising as it did the various components of the laws of pre-IslamicArabia and numerous legal elementstaken over from the non-Arab peoplesof the conquered territories. (4)
另一方面，伊斯兰教则代表着与此前存在的阿拉伯异教(Arab paganism)的一种根本上的决裂;伊斯兰法是从宗教的角度，对各种杂乱无章、绝无共同点的法律内容进行考察所致的结果，而这些法律内容实际上是由前伊斯兰阿拉伯国家(Pre-Islamic Arabia)法律的不尽相同的组成部分以及由从被征服的土地上非阿拉伯民族借鉴过来的无数法律因素所构成。 (as it did )实际上是一句插入语。
难句类型：复杂修饰、插入语
解释：这句话是接着上面的那句话写下来的，是在说伊斯兰法的不一致。句中有三个插入语，都起到了一定的干扰作用。第一个是on the other hand，隔开了主语和谓语。第二个是from a religious angle，分开了examination of ，第三个as it did，根本就是句废话，分断了动词comprise 和动词的宾语the various components。
意群训练：Islam, on the other hand, represented a radical breakaway from the Arab paganism that preceded it; Islamic law is the result of an examination, from a religious angle, of legal subject matter that was far from uniform, comprising as it did the various components of the laws of pre-Islamic Arabia and numberous legal elements taken over from the non-Arab peoples of the conquered territories.
45. One such novel idea isthat (idea) of inserting into the chromosomes of plants discrete genes that are not a part of the plants’ natural constitution：specifically，the idea of inserting intononleguminous plants the genes，if they can be identified and isolated，that fit the leguminous plants to be hosts for nitrogen-fixing bacteria. Hence，(there is ) the intensified research on legumes. (5)，此句最好能够熟读，更好的是背诵下来。(复杂修饰+插入+省略+倒装)
这其中的一个新颖思想就是，在植物的染色体(chromosome)内注入并非是该植物自然构造一个部分的那些不相关联的因基：具体而言，这一思想是，在非豆科植物内注入这样一些基因，倘若这些基因可被辨识出来并被分离开来，而这些基因业已使豆科植物宜于充当那些具备固氮作用的细菌的寄主。由此，对豆科植物的研究日趋深入。
难句类型：复杂修饰、插入语、倒装、省略
解释：本句的难度以倒装为主，复杂为辅;然而二者相互借力，难度更大，而且本句中有两个省略，就更令读者头痛。
句子一开始的One such novel idea is that of 之中的that of, 是thatidea of 的省略形式。此外容易理解，后面开始变难。Inserting into the chromosomes of plants discrete genes(that are not a part of the plants' natureal consttution)看上去不舒服的原因，是作者在此用了一个便装;正常语序应该是：inserting discrete genes(that are not a part of the plants' natureal constitution) into the chromosomes of plants，即把非此植物的genes插入到该植物中。之所以倒装，是因为discrete genes加上复杂修饰的成分以后太长之故。同样，后面的the idea of inserting into nonleguminous plants the genes, if they can be identifyied and isolated, that fit the leguminous plants to be hosts for nitrogen-fixing bacteria一句，正常的语序也是the idea of inserting the genes, if they can be identifyied and isolated, that fit the leguminous plants to be hosts for nitro-fixing bacteria into nonleguminous plants,即把便利豆科植物成为固氮菌的寄主的基因(如果它们能够被找到并分离出来的话)插入到非豆科植物的基因中去。这一回。Genes之后不但有定语从句的复杂修饰，而且在genes和that从句之间还有一个不短的插入语，增加了阅读难度。 感谢您阅读《历年GRE阅读材料难句精选100句(五) 》一文，出国留学网(liuxue86.com)编辑部希望本文能帮助到您。
