在英语中，很少直接称呼别人为叔叔阿姨的，通常都是先生和女士的，所以这一点是区别于我们汉语的！用不着把汉语中的叔叔阿姨翻译出来！以下的译句仅仅是个参考：

Good evening!

　　Ladies and gentlemen,dear teachers and lovely kids,welcome you all coming here to join us,in the Chrismas Day,we“ll show you very excellent perfomance in this great occasion!let“s enjoy ourselves!

　　Dear teachers,uncles and aunts.Thanks for coming to our class and join us.Today is Christmas day,it“s a happy day so let“s have a good party tonight!we“ve prepared a lot of splendid programmes ,just check it out!
