同学们是不是还在为英语成绩的提高而烦恼呢?记得要在平时加强练习。小编为大家整理了剑桥五级阅读难句背诵例句，希望对大家的英语学习有所帮助。

1.Most striking among the many asymmetries evident in an adult flatfish is eye placement： before maturity one eye migrates，so that in an adult flatfish both eyes are on the same side of the head.

在一条成年比目鱼身上显著存在的诸多不合错误称特征中，最为吸人注目的是眼睛的摆位：在成涫之前，一只眼睛发生移动，是以在成年比目鱼身上，两只眼睛均位于头部的统一侧面。

2.The best evidence for the layered-mantle thesis is the well-established fact that volcanic rocks found on oceanic islands，islands believed to result from mantle plumes arising from the lower mantle，are composed of material fundamentally different from that of the midocean ridge system， whose source，mostgeologists contend，is the upper mantle.

对于地幔分层论点来说，最好的证据乃这样一个确认的事实，即在那些海洋岛屿——这些岛屿据信是源于由下层地幔升上来的地幔柱状溶岩流——上发现的火山岩石，是由与海洋中部山脊系统的物质根柢分歧的物质组成的，而这一海洋中部山脊系统的成因，大大都地质学家论辩为上部地幔。

3.Some geologists，however，on the basis of observations concerning mantlexenoliths， argue that the mantle isnot layered，but that heterogeneity is created by fluids rich in “incompatible elements“ percolating upward and transformingportions of the upper mantleirregularly，according to the vagaries of the fluids’ pathways.

可是，某些地质学家，以对地幔捕虏岩体所作的不雅察看为依据，指出地幔并非是分层枚举的，相反，地幔的异质性是由那些富含“不相容成分”的流质组成的，这些成分趋向于流体而非固体的状况，自下而上渗入扩散，并遵照这些流质流向的肆意性，犯警则地将上部地幔的某些部门予以改变。

4.The very richness and complexity of themeaningful relationships that keptpresenting and rearranging themselveson all levels，from abstract intelligence to profound dreamy feelings， made it difficult for Proust to set them out coherently.

各类有意义的联鲜ё仝所有的条理上，自抽象的理性至深刻的梦幻般的激情，层出不穷并不竭从头组号缦愣举;恰是这些有意义的联系的丰硕性和复杂性，致使普鲁斯特难于将它们错落有致地放置好。

5.It is possible to make specific complementary DNA’s that can serve as molecular probes to seek out the messenger RNA’s of the peptide hormones. If brain cells are making the hormones，the cells will contain these Mrna’S. If the products the brain cells make resemble the hormones but are not identical to them，then the cDNA’s should still bind tothese mRNA’s，but should not bind as tightly as they would to mRNA’s for the true hormones.

科学家可以制造出特异的互补DNA’s，以此作为分子探子，探觅出肽激素的信使RNA’s。如不美观大脑正在制造着肽激素，则细胞就会含有这些信使RNA’s.假若细胞所制造的产物近似于肽激素但并非与这些肽激素全然不异，那么，互补cDNA’s应仍然和这些信使mDNA’s粘结的水平。含有这些mRNA’s的脑细胞然后就可以被分分开来，研究者可对其信使RNA’s进行解码，以确定它们的卵白质产物事实是什么，并确定章些卵白质产物在何种水平上近似于真正的肽激素。
