when 引导限制性的后置定语从句,而as 只可以引导非限制性定语从句,如： As is reported/ said that.等等.
she visited her friends in Sydeny last year都是做wonderful time的后置定语从句.所以,这里只可以用when.
望采纳,祝开心~!

先行词是时间，而且关系副词when在从句中作状语；如果用关系代词as,那么必然在从句中作主语或宾语，从句中不缺少主语和宾语成分，所以只能选when。不好意思麻烦你 因为上面那个满意回答我没法追问了 为什么有such a serious problem as we should deal with properly 呢？？谢谢...
