关于since 用延续性动词
He must have taken the book since it isnx27t here. he has put on weight since he gave up smoking since 主句不是只能跟延续性动词吗 这两句中为什么是短暂性动词这两个句中的 since 引导的都是原因状语，而不是时间状语，因此 since 从句并不约束主句中用瞬间动词。第一个句子的意思是“因为这本书不在这里，所以它必定是被人拿走了”，第二个句子的意思是“由于他戒了烟，因此他的体重已经增加了”
since加时间点用延续性动词还是瞬间性动词
两者都可以么?举个例子用延续性动词 如he has lived here since 1999. 如果你问的是 it is/has been.搜趣网.....since.....句型的话 since从句的谓语 可以是 延续动词 也可以是 非延续动词 但意思不一样 如 非延续动词 it is three years since he joined the army .他参军已经三年了。 延续动词 it is three years since he smoked. 他 不 吸烟已经三年了。

then意为“从那以搜趣网后”。
since用作副词表示“以前”时还可和long,
ever连用。long
