I'm using the book A Practical Chinese Grammar to accompany the Practical Chinese Reader II. The PGR is an excellent book and the authors explain grammar very well. I'm puzzled at two of the example sentences, though, and wondered if anyone could explain them for me.
The first is
The second sentence is
The first is
on page 353. Initially I didn't know why the first le was there, but after more reading I assume it is because the person wanted to emphasize that they finished the learning process.Wo3 xue2hui4le qi2 zi4xing2che1 le
The second sentence is
on page 356. I would guess that if the first sentence needs the perfective le then the second one should, too. They both have verb-object constructions, although bicycle is a bit more concrete of an object. Could anyone explain why the two sentence differ on the perfective le?Wo3 xue2hui4 you2 yong3 le
