英语高难度语法
It's three years since I was a teacher.
It's three years since I became a teacher.
第一句中要注意动词“was”是持续动词.一旦是持续动词,全句就是否定.“我不当老师已经三年了.”
第二句中要看动词“became”是瞬间动词,如果是瞬间动词,全句就是肯定.“我当老师已经三年了.”
第一句如果要有他不当老师的意思的话 since必须翻译成自从他.结束后啊
可是字典上没有这个翻译而且字典上通篇用的完成时

你解释的很正确啊,since后面跟的是过去式,那么动作是从停止的时候算起的,就是“不当老师”,如果是瞬间动词,就是从动作发生的时候开始的,
例如
It is ten years since I smoked.表示“我戒烟十年了”
It is ten years since I started smoking.则表示“我吸烟十年了”.
看看这个问题吧,http://zhidao.baidu.com/question/65342530.html和你的是一样的

英语翻译还有这句 It'It's three years since I was a solder.It'It's th It's three years since he was married .的翻译看两个英语句子.It is three years since he was a teacher.他不当老师有三年了.I i have learned it since three years ago.这里since做介词?three yea 英语翻译it is already three years since he was a teacher是他不当教师已经 It three years since I smoked.翻译 It's over three years since I began to learn English.此处的over It's three years since I smoked 这句话什么意思,理解不了 it's years since i it's three years since i came to the school 中's代表的是什么的缩写 It's over two years since I have become a teacher改错 it was three years ago_ i got to know him and since then we
