Nowadays,inviting classemates to dinner is quite popular(or very common) among colleoge students .And whenever there is something that is worth celeblrating ,such as monitor ,they will threat their classmates to inviting for a dinner
However ,this kind of action may lead to some problems.Firstly ,It can cost a lot of money,which may increase their financial burden.Secondly,some students may give a party in a very expensive restaurant just to show off,and this may cause raise(here is better to use raise) a comepetition among classmates.Thirdly,students who have been invited to the party will have to entertain those who have invited them in return ,which contributes to a vicious circle.
