Dear Li Liang ,
　　This June 30th I am going to graduate , so I am going to hold a party on Saturday evening in my house . It would be pleasant to have you here .
　　So interesting will this party be that you can't afford to miss it . For one thing , we can have a big meal , sing the popular songs and play games . For another , it also provides a good opportunity for you to meet many friends that you haven't seen for a long time .
　　What an important thing it is to get your participation ! First , you are my best friend and bring home to me many things , Second , we haven't seen each other for quite a long time and I am eager to see you . The party would not be complete without you !
　　The party will begin at 7:30 p.m . Is it possible for us to see you at 7:00 on Saturday evening in my house ? I do hope you can come .

Sincerely yours ,　　
　　Sun Li
