吊唁信:悼某人丧母-On the Death of Ones Mother(2)

1．非正式请柬一般用于邀请亲戚、朋友等关系较亲密的人出席某种社交场合等。信文像普通书信一样用第一人称，称呼较自由，格式和用语较为随便。例如下面邀请参加生日聚会的请柬：
                                                                                                                            Nov. 2, 1999
Dear Wang Tao,
We are having a birthday party at 7:00 p.m. next Saturday （Nov. 8）at my home and would be delighted if you would join us. We are looking forward to seeing you.
                                                                                                                                     Yours,
                                                                                                                                      Li Ming
它相当于如下汉语请柬：
王涛：
我们定于下周六（11月8日）下午七时在我家举行生日晚会。如果你能参加，我们将十分高兴。期盼你的到来。
                                                                                                                                       李明
