问题 Agronomists are increasingly worried about “desertification,” the phenomenon that is turning many of the world’s (i)____ fields and pastures into (ii)____ wastelands, unable to support the people living on them.

选项 A、fertile…barren
B、productive…blooming
C、arid…thriving
D、poorest…marginal
E、largest…saturated

答案A

解析 空格(ii):
- 方程等号:第二个逗号,同义重复。
- 强词和对应:逗号后面说,这些荒地不能养活土地上的人,所以空格(ii)和unable to support the people取同,体现土地无法养活人类,填入一个负向词。barren贫瘠的,blooming繁荣的,thriving繁荣的,marginal贫瘠的,saturated饱和的,选项A和D合适。
空格(i):
- 方程等号:turning…into…将…转变为…,前后状态取反。
- 强词和对应:空格(ii)和空格(i)根据tuming…into…取反,所以空格(i)应该表示土地“肥沃的”。fertile肥沃的(对),productive多产的(对),arid干旱的(错),poorest最贫乏的(错),largest最大的(对)。综合空格(i),答案选A。
