请大家帮我翻译这几句英语！谢谢大家了！

1。一般外国人不会说can u say itagain. 他们一般只用一个词 pardon 或者是what 直接表达再说一次。
2. I didn't get it. 注意读法连贯，听起来很顺耳。
3. I dont konw 当然是最基本的说法， 可以换成no idea.
4. 视情况而定，最常用的当然还是I can't do。。。。。。
5. Nice to see u guys, I am glad to be a part of this class.
6. Thank you/Thanks.....哥们你不是连这个都不知道吧？？？
7. We can become friends, can we?用个反义疑问句加强下语气.....
哥们你是刚升学要介绍自己吧？真认真。。。。

please say it again或者pardon？
I don't understand what you meant/said.
I don't know或者I have no idea
I don't know。这个要看你具体不会什么，英语中没有明确表示“不会”的单词
Nice/Glad to come here.很高兴来这里，这样就可以了，没有必要强调“班级”
Thank you (for your praise)其实我觉得括号里面的没有必要
I hope I can be your friend.我希望成为你们的朋友

我没有直译，因为我觉得英语有英语的表达习惯

1.请再说一遍 Can you repeat it again?
2.我没听懂你说的意思 I don't understand what you said.
3.我不知道 I don't know.
4.我不会 I don't know how to do it.
5.我很高兴来到这个班级 I am so glad to come in this class.
6.谢谢夸奖 Thanks for your praise.
7.希望和大家成为好朋友 I hope make friends with everyone.

老师会说如下句子：
Good morning teahcer! 早上好老师
Good afternoon teacher! 下午好老师
Good bye!再见
See you next class.下节课见
I am sorry I am late, can I come in ? 很抱歉我来晚了，我可以进来吗？

1.请再说一遍
口语考试，或者礼貌用语就是I beg you pardon ?
但是一般在国外，人们没有听明白对方说什么就会直接一句疑问语气的Sorry?
你可不可以再说一遍

2.我没听懂你说的意思
I didn't get what you are saying

3.我不知道
I don't know
I have no idea

4.我不会
I am sorry that I can't

5.我很高兴来到这个班级
I am so glad that I could be a member of this class

6.谢谢夸奖
Thank you for you compliment

7.希望和大家成为好朋友
Hopefully, we can be good friends
I hope that we can be good friens

1. pardon? please repeat it.
2.I didn't catch you.
3.I have no idea. I don't know.
4.I can't. 根据不同语境译法不同
5.It's my honor to be here/a member of this class.
6.Thanks
7.I hope that we will be good friends.
