题目内容
4.一 It's too late.Why are you still in the living room,Dad?一 Your sister hasn't come back home yet.I for her.( )
| A. | waited | B. | am waiting | C. | was waiting | D. | have waited |
分析 -爸爸,太晚了,你为什么还在客厅呢?-你妹妹还没有回来,我正在等她.
解答 正确答案:B.四个选项都是动词wait用于不同时态的不同形式,A是一般过去时,B是现在进行时,即am/is/are+v-ing,C是过去进行时was/were+v-ing,D是现在完成时have/has+done.根据语境可知"爸爸正在客厅等妹妹回来",表示说话时正在发生的事情,所以要用进行时态,排除AD选项.其次说话双方讨论的是现在的事情,所以正确答案是B.
点评 本题考查现在进行时,无明显的标志词look,listen,now等,所以做题时需根据语境去判断.
