I have a grandpa, he is nearly 70 years old, it sounds old for him, but in his heart, he is really young. Two years ago, when I was in summer holiday, I went back to hometown and visited him. When I used my cellphone, my grandpa could say out which brand it belonged to, he also told me the advantage and disadvantage of my cellphone. I was so surprised, my grandpa said since I went to school, he had nothing to do, so he became interested in the digital products. He is familiar with all kinds of digital products, he is so cool to me. My grandpa is so lovely, he is so fashionable, he is never old.
我有一个爷爷，他将近70岁了，这听起来有点老，但是在他的心里，他很年轻。两年前，当我在放暑假，我回到家乡，看望爷爷。当我用手机的时候，我的爷爷能说出手机属于哪个品牌，他也告诉我手机的优点和缺点。我很吃惊，爷爷说打从我上学起，他就没有事情做，所以他就会数字产品很感兴趣。他熟悉各种各样的数字产品，对我来说他真酷。爷爷是如此的可爱，很时尚，他永远都不老。
