解释:GRE和GMAT考试中比较有特色的一个语言现象是that (those) of的频繁出现。That(those) of的作用是省略掉与前面一样的名词性成分,从而起到简化句子的结构、缩短句子的长度的作用。然而对于初学GRE和GMAT的人来说,由于以前较少遇到这种结构,而且即使遇到也是在比较简单的句子中间遇到的,所以在复杂句式中一旦遇到,往往一下子搞不清楚这个that(或those)指的是前面众多名词性成分中间的哪一个。解决这个问题的办法,就是多读、反复读这样的句子,熟能生巧。 5 A2 C/ c5 k7 C; D9 g 意群训练:A very specialized feeding adaptation in zooplankton is that of the tadpolelike appendicularian who lives in a walnut-sized (or smaller) balloon of mucus equipped with filters that capture and concentrate phytoplankton.
