"He had only just arrived."里面的had为什么不是has?
请说详细一点,最好举几个例子,谢谢.
是随便一句话.

有两种可能1.要看上下文,说此话的人是在什么情况下说的.当然抛去上下文,had和 has都可以,一个表示过去完成时,一个是表示现在完成时.如果他所描述的"他刚刚才到.是描述过去发生的已经完成事情的话,就要用had了,如果刚好所描述的事情是刚好发生在说话时,或之前一点,就可以用has.
2.虚拟语气,这个也是要看上下文: If he hadn't had the message of death of his mother, he had only just arrived without opening his mobile power.如果他没有收到他妈妈去世的消息,那他一定是刚刚到达目的地(下飞机),手机还没开.

应该是由上下文决定的

上下文是过去时

所以这里用过去完成时态

这里显然是用的过去完成时，但是要想解释必须的有上下文，否则没得解释。

用的是过去完成时。表示过去已经完成的动作，并且对现在或过去产生了一定的影响。具体看语境

not that he had to be,as he said on many occasions ,but he was quite capable 6:Tom had a very_____look when he was told not to watch cartoons on TV. 2.He had a birthday party on May 10.(改否定句和一般疑问句 The hungry boy ________ everything on his plate as if he had been starved for ages. The hungry boy ________ everything on his plate as if he had been starved for ages He always had this hang-up about leaving his mother to live on his own. With his attention ___ on the book he was reading ,he didn't notice what had happened. “He wondered if he had bitten off more than he could chew" what's meaning? he had had......怎么连读 “He had already posted the letter by five yesterday.”为什么要用介词"by"?
