题目内容
17.When you are home,give a call to let me know you __________ safely.( )| A. | were arriving | B. | have arrived | C. | will arrive. |
分析 当你到家后,给我个电话让我知道你已经安全到家了.
解答 答案:B
结合句意:当你到家后,给我个电话让我知道你已经安全到家了.可以推断出应该用现在完成时,现在完成时态表示过去发生或已经完成的动作对现在造成的影响或结果.或从过去已经开始,持续到现在的动作或状态.本题属于过去发生或已经完成的动作对现在造成的影响或结果,现在完成时态的构成:助动词have/has+过去分词,根据主语you,可知应该用have arrived.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.
