Dear Harry,
亲爱的哈利，
Congratulations! How glad I am to share your good news!
恭喜！很高兴和大家分享你的好消息！
I think robots are helpful in many ways. And in the future they'll play more important roles in our daily life. Plus, I'm dying to have a robot of my own. I can have it take care of my grandparents when we are not at home. You see, my grandparents are old and cannot move easily. It can help them do some housework such as cooking, cleaning the house and so on.
我认为机器人在很多方面都有帮助。在未来，它们将在我们的日常生活中扮演更重要的角色。另外，我很想有一个自己的机器人。我们不在家的时候，我可以让它照顾我的祖父母。你看，我爷爷奶奶都老了，动不了。它可以帮助他们做一些家务，比如做饭，打扫房间等等。
Hoping you'll make greater progress.
的人希望你能取得更大的进步。
Yours, Li Hua
