Dear Mum,
This afternoon, our teacher asked us list what our parents had done for us. I write down a lot of good sides. Time passes quickly, isn’t it? It is three years when I became a high school student. Looking back on the progresses that I have made so far, I really appreciate for your support. I know that without your properly guidance, I would not have done so well.
However, what still makes me puzzling is how to make my dream to go to the top university come true. Please continue to lend I a hand. I really need your help.
