Grammar Fcus
fr 和 since 在现在完成时中的应用
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” He has studied English fr five years. 他学英语5年了。（2）since后须接“时间点” He has studied English since 1999. 他从1999年开始学英语。
（3）二者可以转换 fr + 一段时间 = since + 一段时间 + ag 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。He has taught here since he came t China.自从他来到中国就在这儿教书。We have been friends since we met in schl.我们从在学校见面起就成为了好朋友。
（5）现在完成时常用句型：It is (has been) +时间段+ since +时间状语或从句It is fur days since last Friday.从上周五到现在已经四天了。（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。
