Dear teachers and friends,
I’d like to say something before Tracy goes back to England. Tracy is a very kind and friendly girl and I feel happy to be her friend. She gets along well with everyone and all of us have a wonderful time with her. Whenever we have trouble learning English, she doesn’t hesitate to help us and our English has been improved a lot since she came to our class. We owe a lot of thanks to Tracy.
True friendship never ends, so I hope we can keep in touch with Tracy. I also hope that Tracy can come back to China and stay with us in the near future.
That’s all. Thank you.
题目分析：欢送辞是当客人离开时，在告别宴会或其他特定场合主人对客人表示惜别之情和表达祝愿时所使用的一种专用文书。
1. 欢送词分为3个部分；称呼语，正文，结束语。
2. 正文是致辞的主体，欢送辞要表达对客人在和大家相处这段时间的难忘之情，回顾彼此交往的过程或经历，同时对逗留期间所见所闻发表感想，并评价对方取得的成绩和建立的友谊及贡献。在正文结束时表达对对方的良好祝福和热切希望。
3. 从语言特征上看，英语致辞的用词要热烈，诚恳，语句要简洁明了，要比较口语化，不要太过咬文嚼字。
4. 常用客套话； We wish…a pleasant time…. May you have a pleasant time…，Wish you a good trip/journey back home! We are looking forward to seeing you again
【亮点说明】Tracy is a very kind and friendly girl and I feel happy to be her friend.这是并列句， She gets along well with everyone and all of us have a wonderful time with her.这句话用了get along with sb“和某人相处”和have a wonderful time玩得愉快， Whenever we have trouble learning English, she doesn’t hesitate to help us and our English has been improved a lot since she came to our class. 这句话用了让步状语从句和have trouble in doing“做…有困难”，We owe a lot of thanks to Tracy.这句话用了词组：owe thanks to sb“向某人道谢”， I also hope that Tracy can come back to China and stay with us in the near future.这句话用了宾语从句。
