今天为大家带来陈琦gre填空强化36套之《
典型的现象解释型(现象+解释+作者评价)
1、内容主旨题(找TS,同义改写即可) 文章首句即为TS,关键词mysterious phenomenon,对应正确选项中的complex and only partly understood。选择B
选项E错在tend to replace, rather than build on, one another,没有提到replace的意思,反而是各个解释相互补充的感觉。
2、推断题
很好定位文中......it will assume the proper northeas terly course to compensate,作者提到compass alone是不能解释上述的compensate...这种现象的,说明compass alone不能使鸟类调整航线。所以当只有compass sense时,鸟群会继续保持原来的飞行方向不变。
3、逻辑加强题
由题干magnetic cues定位到文中最后一句话,发现关键词migrants to determine their geographic location。
既然是逻辑加强题,所以正确选项中要体现出鸟类能determine their geographic location的意思。
选项A,提到了调整飞行路线,即determine their geographic location,正确选项。
选项B,只是提到了passing through a landscape that has been partially altered by a recent fire,并不能说明determine their geographic location。 CDE比较容易排除。
