GRE阅读题型解题技巧解析
GRE阅读对于考生要求较高，词汇、长难句、逻辑结构等，缺一不行。因此做好备考安排，将有助于大家用较少的时间和精力取得更好的复习效果。大家在日常备考过程中，可以在以下方面有针进行界定，GRE阅读的分类也仅仅是为了帮助考生对考试的题型有一个大致的了解。假如你遇到一个考题，虽然能够很快地定位，但是却不是很快地进行选择，那么这道考题就是所谓的示意推理题。
家有双胞胎?宝好、妈好、全家好!
Mothers of twins do not just get twice the bundle of joy—they are also healthier than other mothers
拥有双胞胎的母亲不仅能得到双份的欢乐，而且她们会比其她母亲更健康。
THROUGHOUT history, twins have provoked mixed feelings. Sometimes they were seen as a curse—an unwanted burden on a family’s resources. Sometimes they were viewed as a blessing, or even as a sign of their father’s superior virility. But if Shannen Robson and Ken Smith, of the University of Utah, are right, twins have more to do with their mother’s sturdy constitution than their father’s sexual power.
在历史上，对待双胞胎有着困难的感情。有时，他们被视为祸根--家庭中不受欢迎的负担。有时，他们被视为祝愿，或作为他们父亲拥有更好的性实力的一个标记。，那么双胞胎为他们的母亲那健壮的体格所做的比为他们的父亲的性实力方面所做的更多。
At first blush, this sounds an odd idea. After all, bearing and raising twins is taxing, both for the mother and for the children. Any gains from having more than one offspring at a time might be expected to be like higher infant and maternal mortality rates. On this view, twins are probably an accidental by-product of a natural insurance policy against the risk of losing an embryo early in gestation. That would explain why many more twins are conceived than born, and why those born are so rare (though more common these days, with the rise of IVF). They account for between six and 40 live births per 1,000, depending on where the mother lives.
乍看之下，这似乎听起来似乎是一个惊奇的想法，终归对于母亲和孩子，生产和抚养双胞胎是很费劲的。每次从多于一个孩子那里获得的比期望的更多，通常会伴随着较高的婴儿死亡率和母亲死亡率。依据这种观点，双胞胎很可能是一次在怀孕期间用自然保障方式防止流产的意外的副产品。这样就能说明为何双胞胎怀的比生的多，而且为什么生的会这么少(虽然现在更多的运用试管受精已经很平常)。他们说明说每1000个中成活率在6到40之间，这要依据母亲生活的地方。
Dr Robson and Dr Smith, however, think that this account has got things the wrong way round. Although all women face a trade-off between the resources their bodies allocate to rep
