题目内容
20.Mum,I arrived at the train station twenty minutes ago,but Betty up yet.( )A. | hadn't turned | B. | won't turn | C. | hasn't turned | D. | didn't turn |
分析 妈妈,我20分钟前就到达火车站了,但Betty还没有露面.
解答 答案:C
根据句意可知,此处表示过去的状态(20分钟前我到达火车站时,Betty没有露面这一状态)持续到了现在;故用现在完成时;A.过去完成时表示过去某时间之前的动作或状态;B.一般将来时,表示将来到动作或状态;D.一般过去时指发生在过去的动作或状态;因此A.B.D不合句意;故选C
点评 本题考查了现在完成时的用法.做本题时,首先应根据句意,判断空缺处的动作发生的时间以及所表达的意义;其次,应注意区分现在完成时与过去完成时以及一般过去时的用法区别;因此,做类似的时态题时,需要熟练掌握各时态所表达的意义及用法.
