平行结构
1⃣️首先梳理一下平行结构的标志性词(此处摘自曼哈顿语法):
第一类是开放性的 -and- ;-or-;-rather than-
第二类是闭合性的(此类标志性词有两个) both .A.and .B./ either..or../not..but../not only..but also../from..to...
2⃣️对于第一类,从标志性词右方的结构推出左方的结构,如标志性词左方找到标志性词右方的结构---则平行结构成立
eg.Most fossils of species X were found in F or K -------此句正确,因为or是标志词,其右边K是名词,左边也找到了一个F是名词
Most fossils of species X were found in F or in K------此句也正确,因为or是标志词,其左边结构为介词+n,左边也找到了介词+n
对于第二类,标志性词之间的结构必须一致 即both A and B ,A与B需要平行。
eg.Most fossils of species X were found either in F or in K ------此句正确,因为either 。。or。。是标志词。either后为 in+n ,or 后也为 in+n
Most fossils of species X were found in either F or in K -------此句不正确,因为either 。。or。。是标志词。either后为 n ,or 后为 in+n,结构不平行
3⃣️其他特殊平行标志词
A ,B ,and C 这里标志词是,与,and ------因此ABC都应该平行
此处特别注意对比 A ,B and C 这里标志词只有 and (B and C) 是A的修饰语-----因此只有BC需要平行
313. Found throughout Central and South America, sloths hang from trees by long rubbery limbs and sleep fifteen hours a day, moving infrequently enough that two species of algae grow on its coat and between its toes.
(A) sloths hang from trees by long rubbery limbs and sleep fifteen hours a day, moving infrequently enough
(B) sloths hang from trees by long rubbery limbs, they sleep fifteen hours a day, and with such infrequent movements
(C) sloths use their long rubbery limbs to hang from trees, sleep fifteen hours a day, and move so infrequently
(D) the sloth hangs from trees by its long rubbery limbs, sleeping fifteen hours a day and moving so infrequently
(E) the sloth hangs from trees by its long rubbery limbs, sleeps fifteen hours a day, and it moves infrequently enough
由平行结构可以得出,C与D是对的~
看SLOTH的单复数,由 its coat and between its toes看出,,主语应该是单数的
所以选D
4⃣️不完全对称的平行结构(高分题)
在GMAT中大多数平行结构是比较完美对称的,但是有一些高分题的平行结构并不完全对称
eg. Hand signs that natives use and that appear in local rituals ----正确,and 右边是 that 引导的从句,and左边也为that 引导的从句
Hand signs that natives use and appear in local rituals -----错误,and右边是V 而且V的主语是hand signs,and左边的V是use 但是use的主语是 natives

Hand signs used by natives and appearing in local rituals -----正确,and右边是v-ing 的adj修饰语而且修饰hand signs,and左边是V-ed作为adj修饰语修饰hand signs
5⃣️
83. A report by the American Academy for the Advancement of Science has concluded that much of the currently uncontrolled dioxins to which North Americans are exposed comes from the incineration of wastes. (A) much of the currently uncontrolled dioxins to which North Americans are exposed comes (B) much of the currently uncontrolled dioxins that North Americans are exposed to come (C) much of the dioxins that are currently uncontrolled and that North Americans are exposed to comes (D) many of the dioxins that are currently uncontrolled and North Americans are exposed to come (E) many of the currently uncontrolled dioxins to which North Americans are exposed come
首先CD中都有平行结构指示词 and,但是D中错误平行所以排除
其次modifier不能以prep介词结尾 eg.the restaurant (that) we ate at --错误,(that) we ate at为restaurant修饰语,不能以 at结尾
所以排除BC
最后dioxins可数用many修饰 选E
