1.I am not an outstanding student of yours，but you are the most respectable teacher to me in my eyes. On this special day，I extend my heartfelt respects to you！我不是您最出色的学生，而您却是我最尊敬的老师。在这特别的日子里，我要把一份崇高的敬意献给您！

　　2.No formula can be used to calculate your devotion；no poems and songs to express our heartfelt gratitude to you.It is you that cultivate our minds with your extensive knowledge and your noble spirits.On this special occasion，please accept our best wishes！加减乘除，算不出您作出的奉献！诗词歌赋颂不完对您的崇敬！您用知识的甘露，浇开我们理想的花朵，在这不寻常的时刻，请接受我深深的祝福！

　　3.Time is flying away，and years are passing by.Only our friendship is always in my heart.Farewell，my friend！Take care，my friend！流水匆匆，岁月匆匆，唯有友情永存心中。朋友，再见！朋友，珍重！

　　4.Oh，my friend，do you like stars？If you feel lonely far away from home，look up at the stars in the sky， where there is a star for luck that I''ve send you.朋友，你喜欢星空吗？如果有一天你在远方流浪时感到孤独、忧郁，请抬头看看星空，那儿有我送给你的幸运星。
