Teachers rarely give answers to school assignments when the student hasn't made the effort to complete the assignment.
Provide your answers and you will certainly get some help.
@Shibu Pal -
1 - People are trying to help you. So what have you done to help yourself?
2 - There are only a few (very, very few) teachers offering free help. If you annoy them, if you are argumentative, if you don't make an effort on your own, they will not help you next time.
"I like pizza." Pizza is a noun.
"I like reading." Reading is a noun.
"I like quickly reading books about geography while riding the train."
The entire phrase "quickly reading books about geography while riding the train" functions as a noun (gerund phrase). "Riding" is a participle. "while riding" = "while I am riding" / "while I ride".
