高一全国中学生英语能力竞赛选择填空解题指导（四）

9.语境筛选法

近年来有不断“强化语境,淡化语法”之趋势,故语境在单选题解答中的作用越来越重要。语境筛选法是指先根据语境筛选排除部分选项,从而缩小选择的范围,直至最后选定答案。例如:

—Can you come on Monday or Tuesday?

—I'm afraid ______ day is possible.

A.either B.neither C.some D.any

该题为我们提供了以下两个语境:1.Monday or Tuesday,说明是在两者中选择,由此排除了选项C和D,只能用either或neither;2.I'm afraid由此可知答语为否定,故选B。若为肯定回答,则用:I don't mind.Either day is possible.或I think either day is possible.

10.分类筛选法

分类筛选法,对涉及到时态、语态、非谓语动词、同(近)义词等的试题,可运用语法知识,词义辨异,观察题干,比较四个选项,将其分成两类,排除一类后,再把剩下的一类加以比较,最终确定一个。如:

—You haven't been to the GREat Wall,have you?

—______ .But I'm going there this summer with my parents.

A.Yes,I have B.Yes,I haven't

C.No,I have D.No,I haven't

通过比较四个选项,根据反意疑问句的回答方式,可知B和C为错误答语。然后再根据“But I'm going there this summer with my parents.”,可知答案为D。
