   尽管新GRE单词量减少,取消了“类反”但是难度并没有减少,这更要求考生在新GRE阅读考试中增强逻辑推理能力。虽然逻辑推理能力的考察对我们国内考生来说有点难度,只要保持好心态就能更好的分析新GRE阅读理解句子类型。


  It is possible to make specific complementary DNA‘s (cDNA’s)that can serve as molecular 1 probes to seek out the messenger RNA‘s (mRNA’s)of the peptide hormones 2. 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 3 to these mRNA‘s,but should not bind as tightly as they would to mRNA’s for the true hormones. (4)科学家可以制造出特异的(specific)互补DNA‘s(cDNA’s),以此作为分子探子(molecular probe),探觅出肽激素的信使RNA‘s(mRNA’s)。如果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品类似于肽激素但并非与这些肽激素全然相同,那么,互补cDNA’s应仍然和这些信使mDNA‘s粘结的程度。含有这些mRNA’s的脑细胞然后就可以被分离开来,研究者可对其信使RNA‘s进行解码,以确定它们的蛋白质产品究竟是什么,并确定这些蛋白质产品在何种程度上类似于真正的肽激素。
  难句类型:易混词
  解释:与其他的难句不同的是,心上的英文不止一句。笔者之所以在本句中不设标志和翻译,是因为这三句话从结构和意思上来说并不难。然而很少有人能够真正的一次把这段话读清楚,原因在于两个容易混淆的单词cDNA‘s和mRNA’s在文中交替出现,而且相互作用;再加上brain cell和hormones从中捣乱,更难读清楚原文的意思。原文的主要意思如下:可以用cDNA‘s来探测mRNA’s.如果脑细胞产生了荷尔蒙,则其中必有mRNA‘s意味着可用cDNA探测荷尔蒙。如果脑细胞制造的不是真荷尔蒙,则可以用cDNA’s与其中的mRNA‘s附着的情况来确定此荷尔蒙的真假。
  意群训练:It is possible to make specific complementary DNA‘s (cDNA’s)that can serve as molecular probes to seek out the messenger RNA‘s (mRNA’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 to these mRNA‘s,but should not bind as tightly as they would to mRNA’s for the true hormones.
