老师您好，此题是101网校英语人教实验版高一第8948期的暑假专题（二）中的第12题，答案给的是B，是答案错了吗？ 12. It’s a long time since I enjoyed myself. This sentence means _________. A. I enjoyed myself for a long time B. I haven’t enjoyed myself for a long time C. I want to enjoy myself D. what a long time I enjoyed myself 题中的“ It’s a long time since I enjoyed myself.”是什么意思？指的since的哪种用法？
解题思路： 根据句意和语法进行选择。
解题过程：
解答：
It is +一段时间+since…的句型与It has been +一段时间+since…意思相同。前者是规范说法，后者是口语说法。
It be +时间段+since 从句；自从---以来到现在多久了。
当主句be动词是is/has been 时，since从句中谓语动词用一般过去时；
since 从句的谓语动词为非延续动词（终止性动词）；时间计算一律从since从句的动作完成或状态结束时算起。
It is /has been two years since his father died .他的父亲去世两年了。
=His father has been dead for two years .
=His father died two years ago .
It is /has been four years since he went abroad to further his studies.他去国外深造已经四年了。
since 之后若出现延续性动词，其含义为“不做某事已多长时间了”。
It is three years since I smoked a cigarette .我不吸烟已经三年了。
It’s a long time since he studied English 他好久没学英语了。
同学：
根据以上解释：答案B是正确的。
It’s a long time since I enjoyed myself. enjoyed是延续性动词，所以句意为：我好长时间过的不快乐了。
暑假愉快！
祝你的英语成绩越来越棒！
最终答案：略
