Sample 1
I never drink Coke because it is really bad for my health. I discovered this when I worked with some biologists last summer. We did two simple experiments. In the first experiment, we measured the pH (that is, the grade of acidity [酸性]) of the Coke. We found that Coke has a pH of . That is extremely acidic, and so it is bad for our body. In the second experiment, we decided to examine the effects of high acidity in Coke. We put a shark’s tooth in a glass of Coke. In just seven days, the tooth pletely disappeared; the Coke had dissolved it. If the Coke can do that to a shark’s tooth, what can it do to human teeth or to a human stomach or intestine (肠)? For these reasons, I never drink Coke; and I advise my friends not to drink it either.
Sample 2
Music is my chief hobby; when I listen to music, good things happen to me. If I am lonely or homesick, I listen to pop music. The quick rhythm and the strong beat of drums lift my spirits. If I am familiar with a song, I will sing along with it and my depression disappears. When I am bored or tired, I listen to Mozart. His music makes me feel alive. Music also reminds me of home. Before I came to college, my sisters and I would listen to music and sing songs together every Sunday; and everyone in my family would sit together and cheer us. Now I enjoy listening to music and singing with my roommates because their smiles make me remember the happy times with my family. For me, music is an excellent escape; and without it, I wouldn’t be so happy.
