题目内容：
根据下列文章,请回答题。A New Cause of SufferingA conference on obesity(肥胖症)was recently held in Vienna．Two thousand experts from more than fifty countries attended the conference．According to statistics．1.2 billion people worldwide are overweight，and 250 million are too fat．Obesity is rapidly becoming a new cause of suffering．Professor Friedrich Hopichler of Salzberg said：“We are living in the new age but with the metabolism(新陈代谢)of a stone-age man．1 have just been to the United States．It is really terrible．A pizza(比萨饼)shop is appearing on every corner．We have been occupied by fast food and Coca-Cola-ization．”
Many of the experts stressed that obesity was a potential killer．Hopichler said：“Eighty per cent of all diabetics(糖尿病人)are too fat，also fifty per cent of all patients with high blood pressure and fifty per cent with fatty tissue complaints．Ten per cent more weight means thirteen per cent more risk of heart disease．Reducing one’s weight by ten per cent leads to thirteen per cent lower blood pressure．”
Another expert Hermann Toplak said that the state health services should improve their financing of preventive programs．“The health insurance pays for surgery(such as reducing the size of the stomach)when the body-mass index(身体质量指数)is more than 40．That is equivalent to a weight of116 kilograms for a height of 1.60 meters.One should start earlier．”
Toplak said that prevention should begin in school．“Child obesity has a close relation with the time which children spend in front of T V sets．”How many people are suffering from obesity in the world? A．250，000，000．
B．25，000，000．
C．1，200，000。000．
D．1 20，000，000．
