I wonder why Jenny （ ）us recently. We should have heard from her by now.
A hasn't written B doesn't write C won't write D hadn't written
A hasn't written B doesn't write C won't write D hadn't written
该句表达的意思是：过去的时间没写信，而且更强调现在没收到信，故用现在完成时。
should have done 本应做而未做
答案：A
A hasn't written 用现在完成时表示现在的结果.后一句就说明了结果所以用现在完成时.
D hadn't written
过去完成时
