题目内容
11.I ________this book for about a month,so I have to return it as soon as possible.( )| A. | have borrowed | B. | have kept | C. | have bought | D. | have posted |
分析 我借这本书已经大约一个月了,所以我必须尽快归还.
解答 答案:B 根据for about a month,可知应该用现在完成时态.for about a month是现在完成时的标志词.现在完成时态表示过去发生或已经完成的动作对现在造成的影响或结果.或从过去已经开始,持续到现在的动作或状态.本题属于从过去已经开始,持续到现在的动作或状态,现在完成时态的构成:助动词have/has+过去分词.结合后半句:所以我必须尽快归还,可以推断出前半句是借书,borrow是非延续性动词,不能和表示一段的时间状语for…连用,应该用have kept.故选B.
点评 本题主要考查动词时态,做此类题目要注意时间状语、标志词.根据上下文所表达的含义,做出判断.同时更应记清时态的构成形式.就本题而言主要考查的是现在完成时的延续性动词和非延续性动词,非延续性动词不能和表示一段的时间状语连用,应该用另一个延续性动词来代替.
