请高手帮我翻译一下：妈妈，好长时间没有你的消息了，最近好吗？我很想你，我大学已经开学了。我每天上课都跟认真。过得非常开心。请尽快给我回信。
大家翻译的时候不要用翻译软件，尽量翻译的灵活些。谢谢！！！
參考答案:Mom, it's been a long time before I heard from you, are you ok these days? I miss you a lot, I'm already in university. Every day, I listen carefully in university, and I'm very happy. Please send a letter back quickly!
灵活？不知这个是否灵活。应该很灵活吧。
