One thing you may want to try is to take your corrected sentences and input them in the Baidu dictionary. They have a function that brings up 10 or so other sentence examples using that language. That way you see the corrections in different contexts . That repetitiion is enormously helpful in getting a feel for the language. You gain a sense of confidence when you see the same thing repeated many times in different sentences .

不好意思，我评论发错位置了，应该发在这里的。
