EAP 140 PM - WANG, Lingshan - Week 1 2/3

Today I learned how to write Thesis statement. Thesis statement include main ideal and important details. And I learned three new words: mega,migrate,perspective. From the Bedford handbook,I learned the use of punctuation,and how to use them.But I think they are too much for me,sometimes I confused how to use these punctuation or which one I should use in a sentence.So I need more practice,in order to master the use of punctuation.It is difficult for me to distinguish the comma and unnecessary commas.In some case,I don't know whether we should use comma or not. I think it will be a big problem in my writing if I cannot solve it.
