详解辨别雅思阅读信号词的技巧
3)表转折的信号词
例如however, but, by comparison, nonetheless, nevertheless,这些词往往表示文章观点或方向的重大转变,重点应该关注信号词后面的内容。如‘this definition implies that iconoclasts are different from other people, but more precisely, it is their brains that are different in three distinct ways’, 前半句指出iconoclasts异于常人,用but转折词,强调指出区别的关键地方。这也是选择题‘iconoclasts are distinctive because…' 的出题方向。
4)表让步的信号词
例如although, though, while, whereas, whilst等连接的句子,后半句才是引出的话题和强调内容。 如'He accurately predicted that Venus would cross the face of the Sun in both 1761 and 1769--though he didn't survive to see either’, 前半句讲述他精确预测金星跨越太阳的两次时间,后半句用though引出让步内容,他没有看到任何一次。判断题中‘Halley observed one transit of the planet Venus’主要就是以原文定位句的后半句为判断依据。
5)表举例的信号词
例如for example, for instance, that is to say, such as, include, 后面引出具体事物的详细例子,同时原文中破折号和冒号也有异曲同工之妙,对前面的内容补充说明。如‘in other worlds, the life form we are looking for may well have two green heads and seven fingers, but it will nevertheless resemble us in that it should communicate with its fellows, be interested in the Universe, live on a planet orbiting a star like our Sun, and perhaps most restrictively, have a chemistry, like us, based on carbon and water.' 整句话都在解释说明该段的第二个假设'we are looking for a life form that is pretty well like us’, 所举的例子也是判断题‘SETI scientists are trying to find a life form that resembles humans in many ways' 的判断依据。
6)表顺序的信号词
例如first, second, finally, eventually, later, then, next等,体现出文章内容的逻辑性与发展性。如'In discussing whether we are alone, most SETI scientists adopt two ground rules. First,…Second…’, 使用first 和second这两个序数词,清晰逻辑地讲述了两个重要的假设。这两个信号词,也是这篇文章heading题型段落大意的重点提示。
7)表比较级和最高级的信号词
例如more, most, -est, best, better,exclusively, extremely, superior, preferable,表示事物之间的比较,也是文章要强调的地方。如‘one part is a targeted search using the world's largest radio telescopes, the American-operated telescope’, 该句的the world's largest radio telescopes 对应了题目中the world's most powerful radio telescopes,答案信息就在这里。
