sinceyearsago接什么时态

ago是什么时态?

ago是什么时态?

ago是过去时态的时间标志词。中文意思是“以前”
例如,三年前我带着考上好大学的目的来这所学校读高中,结果发现事不愿违。
For example, three years ago, I came to this school to go to high school with the intention of getting into a good university, only to find that things didnt work out.

since完成时?

since在现在完成时里一般是用来引导时间状语,而且时态多是一般过去时。since表示的时间往往是从过去某一点时间一直延续到说话的时间,意思是“自从…以来”,因而一般与完成时态连用。since 一段时间 ago
I have been here since five months ago. (自从五个月前,我已经在这里了)

since表示具体时间造句?

since three weeks since用于过去完成时
He runs every day since 2000. since一般是加年份,或者一个确切的时间 for一般是指一段时间(1hour、2days...)
Since 1980s,we have not seen each other for thirty-one years. 从1980年起我们互相没有见面有31年了。 Since引导的时间状语从句中时态用完成时,而且常跟for联用

since two years用什么时态?

since two years 本身不成立,正确的说法要么是since two years ago(自从两年前),要么是for two years, 表示动作持续了two years,两种情况下都要求动词是可延续性动词.如: I have been in love with this village since I first came here. 但如果since既然讲,就不再引导时间状语从句,也无上述要求,而是引导原因状语从句了,如:since everybody is here, lets begin,
