请个位帮忙翻译成英文(是给幼儿园老师的感谢信)急!!!

Dear Teacher,
We're Mingyu Liu's parents. Many thanks for your help with my child's study! His orale english has been remarkbly improved! As parents, we are very happy. We hope that we can communicate well and together let's help the kid to improve!
这个信一、有些问题，国外不喜欢直接叫老师，最好根据老师的性别和年龄换叫法，Mr. Miss,Mrs后面跟名字。
二、你儿子没有英文名吗？最好称呼英文名。
三、最好随信有个小贺卡或者小礼物不用太重，不然有点突然。
