题目内容

14．My mother ______ herself busy since she retired from work．（　　）
A．keepsB．has keptC．had keptD．would keep

分析 自从妈妈退休以来，她一直忙着．

解答 答案：B 现在完成时基本用法之一：表示过去已经开始，持续到现在，而且还可能继续下去的动作或状态，常与since或for引导的时间状语连用．根据since she retired from work．可知自从妈妈退休以来就一直忙着，并有可能会持续下去，应该用现在完成时态．现在完成时态的构成：助动词have/has+过去分词，根据主语My mother，是第三人单数，所以应该用has，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，主要考查现在完成时态．
