Then, I did the skill practice in the sheet, I circled the problem markers and highlight the solution markers. I think this lesson is very difficult because I have to read the text and found the problem and solution markers. Some practice I can do it ,but I don't understand. Although this lesson has discourse markers about it ,but I don't understand.
In my opinion, this lesson is very difficult even though this lesson has discourse markers. However, I try to do it and repeat this lesson always in order that I can understand this lesson more.
