1.Please feel free to correct me if I have any errors. 如果我有任何错误，请随意/随便(feel free)纠正/修改(correct)。 2.Was the sentence I just wrote correct? 我刚才写的句子对/正确(right)吗？ 3.Can I say X 我可以说X吗？/我可以这样说吗X？ 4.What does X mean. X是什么意思？ 5.I need you to help me to correct my misstakes. 我需要你帮我改错(correct my mistakes)。 6.Thanks for your time. 谢谢你抽出时间来。Not exactly for help, for instance, when you write a cover letter for a job, you can also put "thanks for your time" in the end, which not necessarily mean help me. 7.Take care. 保重/注意身体。 8.I hope you have a good day. Well, this one is kinda tricky, if you translate literally, it will be 希望你今天玩得开心/希望你今天一切顺利; however, I assume it is a slang for saying goodbye, if that is the case, "再见" will be a better translation, your call.
