答案 The death percentages of different causes in the city during the last three decades have changed significantly.The death percentage by traffic accident has the greatest change from 7% in the 1970s to 21% in the 1990s,while that of other causes has declined sharply from 38% to 25%. The other killers—cancer and heart disease—have also increased steadily by 6% and 11% respectively. These changes reflect the development of the city in the last three decades. People travel more than they did three decades ago,because they are more engaged in business activities and social communications now.As a result, traffic accidents increase.With better diet and longer life.diseases like cancer and heart attack become bigger killers than other kinds of diseases.
