My friend recommanded two English learning books to me.
I found that the grammar teaching in one of them is more detailed than the courses I taken in middle school.
And the content is much more wonderful than the lecturers' explain in college.
I am grateful to her.
Thanks to the suggestion from her, now I discover that things can be easily achieved in right ways.
Human can finish a long journey with a group and may complete a quick trip alone.
However, the accompany with friends is the beautiful scenary along our life.
