One year ago, I was in great trouble. I work hard at English and devoted all my spare time to practise it. But I failed to pass the mid-term exam, which made me great disappointed. So I asked my grandpa for advice when I got to home. Hearing that I told him, he said, “To some extent, exam results sometime can’t truly reflect your ability. You can’t judge your progress by one examination.” He encouraged myself to work hard for long time to check my results. I took my grandpa’s advice. Now my English is much better than ago. From my experience, I feel that we should listen to opinion from old people.

Something in chocolate could be used to stop coughs and lead to more effective medicines, say UK researchers.
Their study found that theobromine, found in cocoa, was nearly a third more effective in stopping coughs than codeine, which was considered the best cough medicine at present.
The Imperial College London researchers who published their results online said the discovery could lead to more effective cough treatment. “While coughing is not necessarily harmful, it can have a major effect on the quality of life, and this discovery could be a huge step forward in treating this problem,” said Professor Peter Barnes.
Ten healthy volunteers were given theobromine, codeine or placebo, a pill that contains no medicine, during the experiment. Neither the volunteers nor the researchers knew who received which pill. The researchers then measured levels of capsaicin, which is used in research to cause coughing and as a sign of how well the medicine is stopping coughs.
The team found that, when the volunteers were given theobromine, the capsaicin needed to produce a cough was around a third higher than in the placebo group. When they were given codeine they need only slightly higher levels of capsaicin to cause a cough compared with the placebo.
