1.fr和since fr后+时间段，表示动作持续了一段时间 since后+时间点，表示动作开始于什么时候，译为“自……以来”[例]I have waited fr tw hurs. 我等了2小时 I have waited since 8 ’clck. 我从8：00 开始等中考高频考点：since 还可以引导时间状语从句 ，含义：自……以来，从句的谓语动词用一般过去式，主句的谓语动词用现在完成时[例] I have stayed in Shanghai since I was 6 years ld. 我六岁时，就住在了上海
[知识拓展]（了解即可）1.since除了可以引导时间状语从句，还可以引导原因状语从句，译为“由于，既然，因为”，此时since后从句谓语动词和since前主句的谓语动词不遵循“主完从过”原则。谓语动词的形式由上下文所决定。[例] I was late fr schl, since it rained heavily. 我迟到了，因为雨下得太大了2.当since前的主句表示时间段，则It has 可以用It 来替换[例]It has been five years since he became a sldier.他当士兵已经五年了 =It is five years since he became a sldier.
