自行车在中国是一种普通而又大众化的交通工具。几乎每人都有一辆自行车。我有一辆黑色的自行车，它已经成为了我的好伙伴。刚买来时，我几乎天天擦拭它。现在由于我学习太忙，就没有再管它。但它仍然能很好地为我服务。
Bike is a common and popular traffic tool in China. Almost everyone owns a bike. I have a black bike. It has been a good friend of mine. I clean it almost every day at the beginning. Now I just leave it alone because of my busy study. But it still does me good service.
