For years experts have argued that poor households are consuming less nourishing food than the rest of the population. But a survey of some of the lowest earners in Britain shows the nutritional value of what they eat is little different to everyone else. In fact, the same deficiencies in diet were shared by all the population and the findings suggest that poor eating choices are far more widespread than previously suspected - affecting many wealthier families. These included low fruit and vegetable consumption, not eating enough oily fish and eating too much saturated fat and sugar. “This is a large and significant study and it shows we are all eating just as bad a diet as each other,” said Tim Lang, professor of food policy at City University. The poorest families were eating only slightly more sugar and slightly less fruit and vegetables, according to the study of 3,728 respondents in the bottom of the population. Alison Tedstone, head of nutritional science at the Food Standard Agency, said: “ Overall, people on low incomes have less than ideal diets, but their diets are only slightly worse than those of the rest of the population.” The study also showed that low earners are choosing to eat unhealthily. Their food choices were not linked to their income, their access to shops or their cooking skills. The findings appear to contradict assumptions that the poor cannot afford healthier foods or are too far away from shops that sell them. The Low Income Nutrition and Diet Survey showed that like the rest of the population, the poor's daily fruit and vegetable intake on average is below the recommended five portions. Fewer than 10 per cent of respondents hit this target, while around 20 per cent ate less than a portion per day. More than three quarters (76 per cent) of men and 81 per cent of women did less than one 30-minute session of moderate or vigorous exercise per week. Some 45 per cent of men and 40 per cent of women were smokers. This compares with 28 per cent of men and 24 per cent of women in the general population. 小题1: According to the passage, which of the following is true? A.Whether the poor or the rich maybe have a bad diet. B.Even the poor can enjoy enough fruit and fish consumption. C.Only the poor have a bad diet. D.The study was conveyed in both the rich and the poor. 小题2:What kind of persons maybe eat most sugar? A.The rich. B.Men. C.The poorest. D.Women 小题3: From the passage, we can learn __________. A.the poor choose unhealthy food because of low income B.having no access to shops also leads to the poor’s bad diet C.the poor’s daily fruit intake is as much as general people D.the number of smokers in the poor is bigger than that in general people 小题4: What’s the best title of the passage? A.The poor’s healthy problem. B.Keep off junk food. C.How to have a good diet. D.A diet survey.

B.
错误
【判断题】联合国粮农组织曾根据恩格尔系数的高低,对世界各国的生活水平进行划分,即一个国家平均家庭恩格尔系数大于 60%为贫穷; 50%~60% 为温饱; 40%~50% 为小康; 30%~40% 属于相对富裕; 20%~30% 为富足; 20% 以下为极其富裕。也就是说,恩格尔系数越低,说明生活水平越高。
