关键词法 许多题目中都有这样一些词.它们对于快速而准确地判定答案起着至关重要的作用.我们称这些词为关键词.找到句中的关键词.也就找到了解题的突破口.例如: He hardly hurt himself in the accident, ? A. doesn't he B. didn't he C. did he D. does he 该题中hardly与hurt是起关键词作用的.凡陈述部分含有hardly, never, little, few等否定意义的词时.反意疑问句用肯定形式,而hurt一词的过去式与原形相同.此处hurt未加s.应为过去式.因此本题答案C是正确的. --- What did you see, Mary? --- I saw a lot of trees on of the lake. A. either side B. all sides C. both sides D. other side 在平时练习中.我们接触的多是下列表达:on both sides of the road / street / river.但本题中lake无两边之分.只能是“在四周 .所以正确答案是B.本题中lake一词成为关键词. 【查看更多】
