题目内容
5.Before moving to Australia,the Browns ______ their cars and house in the USA.A. | have sold | B. | sold | C. | were selling | D. | sell |
分析 在搬到澳大利亚之前,布朗一家就已经卖掉了他们在美国的车和房子.
解答 答案:A
根据句意可知,本句表达的是过去(即指搬到澳大利亚之前)的动作对现在造成的结果,即布朗一家现在在美国已经没有车和房子了;所以这里应使用现在完成时;B.一般过去时,表示发生在过去的动作或状态,不强调对现在造成的影响;C.过去进行时表示在过去某一时刻或某一段时间内正在进行或发生的动作,不强调是否完成;D.一般现在时表示现阶段经常性,习惯性的动作;由于B.C.D不合句意,故选A
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,判断出空缺处的动作发生的时间以及它所表达的意义;其次应熟练掌握各时态所表示的意义以及它们之间的用法区别.
