题目内容
17.When you are home,give a call to let me know you safely.( )A. | are arriving | B. | have arrived | C. | had arrived | D. | will arrive |
分析 当你到家后,打个电话告诉我你已经安全到家.
解答 答案B.
本题主要考查动词时态.根据题意可知,这里要表达"回家后打电话确认已经安全到达",所以应该用现在完成时,答案为B项.A项和D项均表示将来,没有"完成"之意,所以排除;C项为过去完成时,不符合题意,所以排除.故选B.
点评 时态题的考查关键是抓住句子的上下文含义和句中的时间状语.要根据时间状语来选择合适的时态,在平时的学习中要注意积累有关时态的用法和各种时态的特殊之处.
