Dear teacher
亲爱的老师：
Hello!
您好！
Your care is as warm as the sun, as warm as the spring breeze, and as
sweet as the spring. We are like flower seeds, sprouting and growing
under your care and cultivation.
您的关怀犹如太阳般温暖，春风般和煦，清泉般甘甜。我们就像一粒粒花种，在您的关怀和栽培下，萌芽、生长。
Teacher, you pay for us wholeheartedly. You teach us hard every day. In
the evening, you help us check our homework and prepare lessons. You
seldom get a good sleep. You treat us as your own children.
老师，您一心一意为我们付出，每天辛苦地给我们讲课，晚上还要帮我们查作业，备课，很少能睡个安稳觉。你把我们当亲生子女一样对待。
Teacher, you are like a candle, silently burning yourself and
illuminating others; She is like a gardener, nurturing the flowers of
our motherland.
老师您就像一根蜡烛，默默地燃烧着自己，照亮着别人；她就像一个园丁，培育着我们这些祖国的花朵。
Looking back on the past course, every achievement of us is condensed
with your hard work and sweat; Every progress we make is inseparable
from your help and instruction. Your greetings, help and care are deeply
engraved in my memory.
回顾以往的历程，我们的每一点成绩，都凝聚着您的心血和汗水；我们的每一点进步，都离不开您的帮助和教导，您的每一次问候，每一次帮助，每一次关怀，都深深铭刻在我的记忆里。
I want to say to you: "teacher, I love you!" I wish you peace, happiness and good health every minute of your life!
我想对您说：“老师我爱您！”祝您在人生的大道上每分每秒都平平安安、快快乐乐、身体健康！
Sincerely
此致
