1
should + 动词一般时态,表示建议别人应该怎样做,而should + 动词现在完成时态表示本应该怎样做但实际没有那样做.动作已经完成了,但与说话人的期望相反.
瞧,看你都做了些什么呀!你本该更细心些的.
b c d 都不能表达出这样的意思.
2 从英格兰旅行到苏格兰,你不需要护照.
其中,“需要”是作为实义动词,而不是助动词.
need 做实义动词时候,其否定形式是 don't need.
needn't 这种形式中,need 是助动词.如果使用这种形式,后面还要加某个动词,比如 needn't have.
3
为什么马丽还没有出现?我想可能是火车被耽误了.
从句子的意思看,火车晚点这件事情已经发生,并对现在产生了影响（导致马丽还没到场）,所以需要使用完成时态.might 是助动词,表示一种猜测.
