by the end of有后接现在完成时的例子吗?

问题描述:

by the end of有后接现在完成时的例子吗?
(1)by the end of this year,句子为一般将来时,例:
Chinese population will pass 13 billion by the end of this year.到今年年底中国人口会超过13亿.
(2)by the end of last year,则为过去完成时,例:
I hade learned more than 5000 words by the end of last year.到去年年底我已经学了有5000个单词了.
因为by the end of 就是到某个时间点为止的一段时间内,那应该不是过去就是将来啊!有没有现在完成时态的例子呢?

By the end of this week ,I have written (write) two books .
