我可以說(shuō)清楚~
填寫(xiě)：Did ,used to
1.used to do something 指的是過(guò)去常常做某事,或者過(guò)去曾經(jīng)做某事
此處整句話的意思是甲問(wèn)：你過(guò)去抽煙嗎?回答：抽煙,但是我現(xiàn)在已經(jīng)戒煙了.
因此正確的答案是上面我說(shuō)的.
2.你提到的be used to ,可以有2種情況.
A.be used to do something.被用來(lái)做某事
eg.The knife is used to cut .
B.be used to doing something.習(xí)慣于做某事.當(dāng)然,be used to 后面也可以加名詞.
eg.We are used to getting up very late every moring.
He is used to hard work.
