must write one discussion and two replies, I will post my classmates’s
discussions, you can according to their discussion, write two replies
respectively. The discussion should write about 300 words, and each
reply should write 200 words. Do not write more than the words. According
to the problem, you can choose a common thing. And you can also have a
consult about the discussion I posted. But do not copy, Express more
your own opinions.

Tips
for success: Remember to choose a problem that is not too broad, too
speculative, or too complicated. However, you can focus on a difficult
or challenging problem. Consider focusing on a local problem. Choose
something that is significant or meaningful to you–perhaps something
that relates to your major, your profession, your current job, your
community, or your extra-curricular or volunteer activities.
