题目内容
16.He is working as a teacher of English in our school and he in the U.S.Air Force for four years.( )A. | has served | B. | had served | C. | served | D. | was served |
分析 他在我们学校当英语老师,他还曾在美国当了四年的空军.
解答 答案:C
根据句意以及句中"is working"使用了现在进行时可知,他现在正从事的工作是在我们学校当英语老师;因此在美国当空军应是过去的事情;故此处表示的是过去发生并且现在已经结束的动作,应使用一般过去时;这里不能选A;因为现在完成时表示发生在过去并且延续到了现在的动作;故选C
点评 本题考查了一般过去时的用法.做本题时,首先应通过分析句意,进行逻辑推理.从而判断出句子应使用的时态;其次应熟练掌握一般过去时的意义及用法;还应注意总结一般过去时与现在完成时的区别.
