since when用法
That was in 1929,since______ things have been better.
A.which B.when
为什么答案选 B when 不选 A which 呢
这是定语从句,先行词是1929,things have been better中主谓宾俱全,因此1929在句中做时间状语.不是since when的用法
after since when 用法 since when用法 when和since的用法 英语when,while,since,for的用法? when while since 的区别,及用法 since when引导定语从句的用法? since when的意思,用法,例句 since 和 when用法的区别 since when 这个词组和since always 这个词组的 用法 还有since ago while,when,during,since,for的用法及区别 since when和since since then &since when
