Hello

On September 1st,  the new term starts and my children will return to their middle school, new term starts for them. Today, they went to back their school to collect for some new textbooks, in the afternoon, their mother, (my wife) took them to shop for some stationery. paper, pen etc.
They will step into be in the eighth grade, and will learn a new subject,course or lesson, Physics. They had learned some of the book in advance during the summer break, and feel very good about this to the new subject course. I am glad my children feel this way can have the strong sense to the new course because most children have difficulty wilth Physics. can not understand the course very well.
A new term start means nightmares start for them, because many there will be a lot of homework waiting for them. Here, I just want to say, "My children, good luck!"
