      凡是出现but, yet, however, nevertheless, although, (even) though, while, whereas, notwithstanding, despite, in spite of, in contrast (to), on the contrary, on the other hand, whatever, otherwise, ironically, paradoxically, curiously, surprisingly 等带有转折逆转含义的题目,则代入空格的正确选项必与中心线索构成语义对立的反义词关系。

      例Ⅰ:

      It is true that seeds of some plants have --------- after two hundred years of dormancy, but reports that viable seeds have been found in ancient tombs such as pyramids are entirely ---------.

      (A) received ... empirical

      (B) germinated ... unfounded

      (C) endured ... irrelevant

      (D) erupted ... reasonable

      (E) proliferated ... substantiated

      〖解答〗

      先处理空格Ⅱ:题内"It is true that..."代表了第一种说法,"but reports that..."代表了与第一种说法相反的情形。既然前者是“确凿可信的”(true), 则后者应是“虚妄谬误的”,与true一词构成反义。(D) reasonable 和 (E) substantiated (具体化的,被证实了的)构成的是同义关系,可先予排除。(A) empirical (经验主义的)无针对性。(C) irrelevant 意为“不相关联的”,它并不就意味着“谬误的”。唯 (B) unfounded (没有根据的,无稽之谈的)为正确。在空格Ⅰ处,所代入的动词用以描述 “seeds” 的某种情况,可将第二句中再涉及seeds这一概念时所用的viable一词以动词形式直接代入,则求得同义的(B)germinated一词。

      〖中译〗

      某些植物的种籽在经历了两百多年的休眠状态之后依然能发芽,这一情形完全属实,但是,在诸如金字塔一类的古代坟墓中能寻找到尚能存活发芽的种籽,这样的传闻纯属无稽之谈。

      例 Ⅱ:

      Even though some genetic mutations may be useful under certain circumstances, most are unconditionally --------- in all existing environments.

      (A) expendable

      (B) androgynous

      (C) prevalent

      (D) ancillary

      (E) deleterious

      〖解答〗

      以Even though 引导的让步状语从句与主句构成对立相反的关系,将中心线索定位于useful一词,则求得其反义词(E)deleterious(有害的,造成伤害的)。

      〖词汇〗

      expendable: 可消耗的

      androgynous: 雌雄同序(体)的,两性畸形的,(服饰等)男女不分的

      prevalent: 普遍的,盛行的

      ancillary: 从属的,附属的,辅助的

      〖中译〗

      尽管某些遗传变异在有些情况下不无益处,但绝大多数此类变异在现存的所有环境中均是绝然有害的。
