can`t be 是指不可能是，有客觀性could not have been 有主觀的猜測 ，況且乘車這個(gè)動作是發(fā)生在過去，要用過去完成時(shí)像這些問題，抄在一個(gè)本子是多讀狂讀到時(shí)候就自然會做了

注意時(shí)態(tài)為過去式

熱心網(wǎng)友

can表推測時(shí)常用于否定 過去時(shí)用could

熱心網(wǎng)友

這是一道虛擬語氣的題目，表示對過去的推測，所以用過去完成時(shí)，所以只能選D.

上句是過去式,后一句應(yīng)互相照應(yīng),所以A答案不行B項(xiàng)只是簡單的過去式,D項(xiàng)用完成時(shí)表示上句話的影響,故比較起來D項(xiàng)好C項(xiàng)mustn't是禁止的意思
