Question

a.  I'm sorry. I was absent from the class because I had a bad cold,  so I can't answer this question.

b.  This websites are useful but those are also hard for me to master using this.
 However,if I was able to control this websites,my computer and English skill would step up.
So I want to study hard in this class.

c.  I studied reviewed vocab.I found that I don't have a large vocabulary  at that time.
I think vocabulary is very important.

d.  I'm not good at listening English. So I should listen to Western music.
I want to catch the words and understand the meaning.

Thank you.Good bye.
