找位英语高手来看看有无语法错误~

good nootime-->如果是12点左右干脆说good day。根据具体情况选择，没有 noontime这个词，也没有这样打招呼的。
Thank for..->Thanks for all of you coming here
stand for-->这种情况“代表”一般用on behalf of的
注意人称，前面称aunt 和uncle为第三人称，后面却变成了your beautiful..

你这个祝酒词不行的，说的有点空洞，而且句子太中国化。可以参考一下 princess8812的。根据实际情况说一些实在的话。另可参考老友记中类似场合的台词

good nootime错误，如果是晚上，要用goodnight。

Today is the wedding ceremony for my aunt and uncle.
我觉得用of代替for.
Thank for all of you come here.应该是thank you

I stand for myself and my famliy wish my aunt and uncle love each other forever,join hands and spend your beautiful life together.Wish you a happy wedding.
这句话变成两个动词，语法上是行不通的。wish前应该加个to吧。还有既然是对来宾讲的，your要改成their，spend their beautiful life together.最后一句话如果是要表达让来宾享受婚礼的话，应是加上enjoy,Wish you enjoy the wedding!

有挺多问题的，我帮你改下： ladies and gentlemen，good morning／afternoon／night（时间你看情况）Today is the wedding ceremony for my dear aunt and uncle. Thanks for all of you to come here to share our happiness
