                                                                  Never give up

      Since I was young, my mother has always spent lots of time sitting be-hind a sewing machine (缝纫机)

with a happy look on her face. For all the three kids in our family, she has made all the clothes.

      My mother makes it look so easy, but the first time I tried to make something, I just couldn't do it. I

worked too quickly, and when I finished, it looked bad. Soon, I just gave up.

      This summer, I really wanted to make a dress to wear at a party. I picked out some nice cloth, and I

found a nice style in a book. I got so excited about sewing that I couldn't even sleep.

       I started early the next morning. My mother was at a meeting, so if I had questions, there could be no

one to ask.

       I started sewing slowly and carefully, and I tried to do everything right. When I was sewing the top, I

made the neck too small. But the rest was fine.

      "I finally made it!" I shouted two hours later. And it fit! For the first time, I couldn't wear something I

had made with my own hands!

      If you want to learn something, my advice is: Don't give up when you can't do it well. Start with

something easy, and try your best.
