German scientists say that eating a little chocolate every day may keep you away from cardiovascular(心血管的) disease. The scientists have found that chocolate, especially dark chocolate , can help you cut down 39 percent of heart disease, including taking a very small amount . However, the study advises people not to eat too much chocolate, because too much chocolate is bad for our bodies. So the scientists advise people to eat small amount of chocolate instead of sugar or high-fat snacks.
Scientists said, “Dark chocolate shows the greatest effects, milk chocolate fewer , and white chocolate no effects.” The results showed chocolate may cut down blood pressure, but they also say that further study is needed.
In the eight-year study, people’s daily diet, exercise habits, and blood pressure were studied in 19,357 persons aged 35 to 65. They found that people who are an average of 7.5 grams of chocolate a day had a very lower chance of heart disease than those who ate much less chocolate , and average of 1.7 grams a day.

When I was young, I liked to play jokes on people I knew, especially on my parents and friends. One day my mother was cooking in the kitchen and my younger brother was playing near the window. I ran to my mother and said, “My brother has fallen from the open window!” She was very worried about my brother and then I said, “Don’t worry. I’m just joking.” And my mother shouted at me, “If you do it again, I’ll punish(懲罰) you.”
One day I went swimming with my friends in the sea. I wanted to play a joke on my friends. In the beginning, I went swimming alone, and I called to my friends, “ Help me!” All my friends came to help me, only to find out that I was joking. But the next time I wasn’t joking.

In the end, they found I was telling the truth(真話). They came and saved my life. They took me to the emergency center. From then on, I haven’t joked on anyone.
