---My Dad began to teach me English when I was eight.
---Wow. You must have studied English for six years, ?| A．haven’t you | B．mustn’t you | C．needn’t you | D．don’t you |

答案
| A |
解析
试题分析： 句意：--我爸爸在我8岁的时候开始教我英语。--哇哦，你一定是学习英语6年了， 是吗？很明显这是一个反意问句，前面的陈述句部分用must have done是对过去的推测，反意问句要看时间，如果陈述句有具体的过去时间，就用一般过去式，如果陈述句部分没有具体的过去时间，就用现在完成时，这里的for 6 years是和现在有关的时间，用现在完成时，选A。 |
