Question

【题目】— He promised to travel with you .
—But he __________ . I have been just with myself all the time .
A.doesn't
B.isn't
C.hasn't
D.won't

Answer 1

【答案】C
【解析】句意：—他答应和你一起去旅行。—但是他没有。我一直是一个人。doesn't一般现在时态的否定形式；isn't不是；hasn't现在完成时态的否定形式；won't不会，一般将来时态。根据句意和后面句中I have been just with myself all the time可知，这里应该用现在完成时态。故选C。
