by the time后一定要接完成时态吗例如By the time,i will be very stronger.
好多时候还真得靠自己的感觉去说.
我觉得应该是说去年那时已经是完成了这个命令( had been instructed),也就是说强调的是这个记者 (journalist)去年已经被命令写那篇文章了,而不是强调他被命令这个动作.当然这句话也能用 was instructed ,但结果就是强调被命令这个动作了,而没说是否已经完成了这个动作.这句子用过去完成时隐含他已经完成了这个命令的意思.
个人见解,仅供参考!

不对
by the time of...
比如 by the time of next year, we will have learned 1000 words
by the time of last year, we had learned 100words.
取决于of后面的时间是将来的还是过去的
要是将来的,就用will have done
要是过去的,就用 had done
