  作为考试题型之一的FIB不仅仅考察学生对词汇的精确理解,还需要我们对原文准确分析,因此要求学习基本功足够扎实,下面我们就为大家带来了PTE考试中的机经!

  A Dog may be man's best friend. But man is not always a dog's. Over the centuries selective breeding has pulled at the canine body shape to produce what is often a grotesque distortion of the underlying wolf. Indeed, some of these distortions are, when found in people, regarded as pathologies.

  Dog breeding does, though, offer a chance to those who would like to understand how body shape is controlled. The ancestry of pedigree pooches is well recorded, their generation time is short and their litter size reasonably large, so there is plenty of material to work with. Moreover, breeds are, by definition, inbred, and this simplifies genetic analysis. Those such as Elaine Ostrander, of America's National Human Genome Research Institute, who wish to identify the genetic basis of the features of particular pedigrees thus, have an ideal experimental animal.

  狗可能是人类最好的朋友。但是人并不总是狗的。在过去的几个世纪里,选择性繁殖一直在利用犬类的体型来制造一种通常是狼的怪异变形。事实上,当在人身上发现这些扭曲时,有些被视为病态。

  然而,对于那些想要了解如何控制体型的人来说,养狗确实提供了一个机会。纯种狗的祖先有很好的记录,它们的繁殖时间很短,而且它们的产仔数量也相当大,所以有大量的材料可以研究。此外,根据定义,品种是近亲繁殖的,这简化了遗传分析。美国国家人类基因组研究所的伊莱恩·奥斯特兰德(Elaine Ostrander)等人希望确定特定血统特征的遗传基础,因此拥有了一种理想的实验动物。


PTE考试中的机经训练真题(一)


  答案

  1. excellent excessive selective selected

  2. diseases epidemics pathologies medications

  3. puppy little litter offspring

  4. Hence However Moreover So

  5. representative expected general ideal

  1. selective:缺形容词,根据句意“几个世纪以来,一些品种的狗从狼中选出来陪伴人类”。

  2. pathologies:缺名词,根据句意“如果这些变异发生在人类身上,就会被认为是一种病变”。pathologies, 表示病态.

  3. litter:litter-size 表示产仔数量。

  4. Moreover:缺副词,前句提到狗的好处,后面也提到“简化遗传分析”也属优势,所以这里表示递进,选择moreover。

  5. ideal:缺形容词,前文描述狗这种动物的好处,根据句意“拥有了一种理想的实验动物”。
