In reaction to the idea,many people say they often take part in various lectures.Of course,a number of factors could account for the choice.Contray to generaly accepted views that it's required to do so,I argue that they,the abundant lectures,cost a large fortune.

    Personal experience shows that there are a number of positive effects on campus lectures:For one thing,the increment of my knowledge accelerates through a series oflectures about subjects on diverse levels.For another,they acquainted me with other fans who enjoy the same topics.

    From what has been discussed above,we may draw the conclusion that to participate in lectures is an experience which should be cherished in our campus life.
