题目内容
4.--What a pity!You missed the beginning of the movie,it _ _ for 10minutes.--Oh,a traffic jam!( )
| A. | began | B. | stated | C. | has been on | D. | has been off |
分析 太可惜了,你错过了电影的开头,已经开演十分钟了.
--哦,交通拥堵!
解答 答案:C 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.结合句意,根据for 10 minutes,可知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it是第三人单数,所以应该用has.be on,开始,上映,表示一种可延续的状态;be off,离开,取消.故选:C.
点评 本题主要考查动词时态,做此类题目一定注意时间状语、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.
