为什么不是A,完全倒装,表系主结构?

1条件状语中的时间状语｛when｝中,用一般现在时表将来时
2中文翻译
3先中文翻译,就是在两个月前,他才开始在这里工作,强调两个月前,与句子前面相吻合,强调结构,when 语法错误,when要修饰具体的时间点,如果你说是in march ,那么不能用when,因为有in
4猜测,may可能,有时会BC排除,句意不对Dshould助词 ：
1.(shall的过去式,表示过去将来)将
We hoped that we should be able to do that.
我们希望我们能这样做.
2.(表示语气较强的假设)万一,竟然

万一汽车中途抛锚,你就得走回来.
3.(表示可能性、推测、推论或期待)可能,该

9.(表示结果、意愿等)就,该
10.(表示征求同意等)可以,该

关于我的日程该和谁商讨?（百度）
义务应该,按常理应该,都是对将来的猜测,建议的语气比较强烈,当然should的特殊用法：竟然除外
5.it is said that sb have done something=sb is said to have done据说某人已经做了某事,完成时,be donging 是现在进行时
6特殊得倒装,你记住几个例句吧（背下来,没有为什么）
young as he is ,he knows a lot
much as i love he ,i still do not want to marry him
child as he is ,he knows a lot
提于句首的是形容词,名词（无冠词）,副词,although=as（在此用法上）
