请帮我看看这段英语是否有语法错误。

hi,Roger,It was（is，现在时） my first message to（for，表对象） you.

My English is not so（改成that，更地道，that有很，非常的意思） good that（改成so，表原因） the message will be（现在发生的事情，就用is） short and maybe there will be（同理改成are） a lot of grammatical errors.（一般的错误就用mistakes ）

on the Australian Open,the weather is so hot.（语序要调整，才更地道，把on the AO调到后面那句话后面去）How did you adapt to it and faced with different opponents, how you feel？（太突兀，改成，and how did you feel when faced with diffrent opponents)

Last,I hope you will have(改成gain） access to a growing number of honoraty（就是honors）.and as a Chinese,welcome you once again came to my motherland.（缺主语，as a Chines，I welcome you came to...once
again。 once again 要放到最后）

Thank you for your time. （有点chinglish，改成thank you for your attention!)

内容很完整。就是有些用词改了以下。还有就是语序问题。楼主要多读多背。这样句子才能地道

保证是很用心很用心改的 也改正的很到位 让你文章更加原汁原味 有什么问题还可以和我继续探讨O(∩_∩)O

It was my first message to you.
我给你改的是This is my first message to you.

My English is not so good that the message will be short and maybe there will be a lot of grammatical errors.
我给你改的是My English is not so good, therefore this message will be short and maybe full of grammatical mistakes.

on the Australian Open,the weather is so hot.How did you adapt to it and faced with different opponents, how you feel？
我给你改的是 It was so hot during the Australian Open. How come you managed to conquer it and beat different opponents? What was your feeling then?

Last,I hope you will have access to a growing number of honorary.and as a Chinese,welcome you once again came to my motherland.
我给你改的是Finally, I hope you can achieve further and greater glory. And as a Chinese, I wholeheartedly welcome you to our country again!

1.It was my first message to you换成it was the first time that I left message to you好点，
2.errors换成mistakes好点，
3.How did you adapt to it and faced with different opponents, how you feel？换成How did you adapt to it and face different opponents,how did you feel?
4.last换成at last，
5.welcome you once again came to my motherland换成I will welcome you once again when you come to my motherland.
以上个人意见，仅供参考。

on the Australian Open,the weather is so hot.How did you adapt to it and faced with different opponents, how you feel？
最后的那个应该是How did you feel
Last,I hope you will have access to a growing number of honorary.and as a Chinese,welcome you once again came to my motherland.
那个came应该用come 还有I hope you will have access to a growing number of honorary 把have去掉也可以

也就这么多了吧
