This June 30th I am going to graduate, so I want 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 will 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 for me to get your participation.
