For the first question,my answer is yes.Generally speaking,the higher education a person received,the more service he will do for the society.In the education process,you must see or learn how other people do social service.And then,you will do the same thing as them.After a long time,a habit will go with you.
I have service experience,of course.The first service which I still remember is looking after tha aging people in the hospital.I was 15 years old then,and that was a cold winter.My teacher and my classmates bought some fruits to the hospital.Then we talked to them and do some cleaning and washing for them,because their children can not see them frequently.They are very lonely,so our help to them is meaningful.After that,I also go to museaum to become a volunteer to introduce for foreigners and do some work for the library.
In my spare time,I often surf the net to find a part time job,also some volunteer's work.
呵呵，但愿对你有所帮助吧~这是我自己想的~
