First, in the past I seldom read books. I used to spend most of my time playing computer games.
Now I like reading because good books help me relax after a busy day.
Second, I always dropped litter carelessly in the park. But now I have realized the importance of
protecting the environment. I always throw the litter into the rubbish bins.
Third, I used to be impolite. I sometimes shouted loudly or pushed in before others in public. Now,
I can behave politely in public, and I often give my seat to someone in need on the bus.
Fourth, I cared little about others. But now I offer to donate all my pocket money and my books to
the children in poor areas.
