Present Perfect Tense
表示从过去已经开始持续到现在的动作或状态，可以和表示“从过去某一时刻延续到现在的一段时间状语”连用，如“fr+时间段”、“since+过去时间点”、“since+过去时的从句”、“since+一段时间+ag”。且fr与since引导的时间状语可以相互转换。
e.g. My uncle has wrked at this factry fr ten years. = My uncle has wrked at this factry since ten year ag. I’ve lived here since 1990． 自从1990年以来我就住在这里。 I haven’t seen him fr three years. 我三年没有看见他了。
She’s been at this schl since fiveyears ag. 自从五年前她就在这个学校。含有fr，since的现在完成时的用法歌诀: 过去的动作或状态，一直持续到现在，fr、since 把时间带。
fr与since都能与现在完成时连用，但区别较大：（1）fr后须接“时间段” e.g. He has studied English fr five years. 他学英语5年了。（2）since后须接“时间点”e.g. He has studied English since 1999. 他从1999年开始学英语。
fr 和 since 在现在完成时中的应用
（3）二者可以转换 fr + 一段时间 = since + 一段时间 + ag e.g. He has been here fr five weeks. = He has been here since five weeks ag. 他到这儿已经有五个星期了。（4）since能引导时间状语从句（主句用现在完 成时，从句用一般过去时），而fr则不能。e.g. He has taught here since he came t China. 自从他来到中国就在这儿教书。
（5）现在完成时常用句型：①It is (has been) +时间段+ since +时间状语或从句 e.g. It is fur days since last Friday.从上周五到现在已经四天了。It has been tw years since Jim came t Beijing.吉姆来北京已经两年了。
②This is the first (secnd…) time that + 从句 句型中的that从句通常使用现在完成时。e.g. This is the first time that Jenny and Danny have been t China. 这是珍妮和丹妮第一次来中国。 This is the third time that I have seen Karen. 这是我第三次见到凯伦。
（6）均须与延续性动词连用，也可以与非延 续性动词的否定式连用。e.g. I have had this cmputer since fur years ag. I haven’t bught anything fr tw mnths.I haven’t heard frm him fr 3 weeks.
（7）二者引出的时间状语往往用 hw lng提问。e.g. — Hw lng have yu had this bk? — Fr a week./Since a week ag. — 这本书你买多久了? — 买一周了。
