问题    According to two recent research papers, sugar is toxic enough to kill mice and is the drug of choice for laboratory rats, which prefer it to cocaine. Now it has been called " the most dangerous drug of this time" by Paul van der Velpent, head of Amsterdam’s health service. Velpent called for government restrictions on sugar in food and a ban on soft drinks in schools. An anti-sugar movement is emerging. Endocrinologist Dr Robert Lustig’s lecture, Sugar: The Bitter Truth, has picked up four million views on YouTube. The latest National Diet and Nutrition Survey shows all age groups exceeded the recommended 11% of energy coming from sugars added to foods. For children aged between 11 and 18 the mean intake was 15. 3%. Since the survey is self-reported it is likely that most people underestimate their intake.
   Why are we eating more? We like sugar and manufacturers have made some foods sweeter. An analysis found that Hovis wholemeal bread had doubled in sugar content between 1978 and 2013. A meta-analysis paper (that combines the results of studies) published this year found that increased intake of sugar led to weight gain. It also showed that children who had one sugary drink a day were 55% more likely to be overweight than those who did not. An accompanying editorial argued that sugar interferes with metabolic processes that protect against diabetes and heart attacks.
   Another study found that replacing 5% of calories from saturated fat with calories from sugars or other high-glycogenic-index carbohydrates increased the rate of heart attacks by 33%. A Princeton Review study found that rats experienced changes to the dopamine and opioid receptors in their brains after being flooded with sugar. This made them sugar-dependent. The authors queried whether adults could also develop a dependency.
   Whatever the conclusion, it is worth cutting down on sugar. Be aware of how much your food contains. Fat-free products often have high sugar levels to make them tasty, so try to avoid them. More sleep will also make you less likely to crave sugar. Recommended limits are 50g a day in a 2 000-calorie diet. A teaspoon is 4g. So now you know. [br] Which of the following is the method to help people reduce sugar intake according to the passage?
选项 A、People should eat more fat-free food, which can help them avoid obesity.
B、People should eat no more than 13 teaspoons of sugar a day in a 2 000-calorie diet.
C、People should intensify exercise every day.
D、People should have more sleep in order to control the desire for sweet food.
答案 D
解析 题目要求选出抵制糖分摄入的方法。文章在第一段和最后一段都有相关的方法介绍。在第一段中，Velpent呼吁通过政府和学校来进行抵制。而文章最后一段介绍了一些人们自我约束的措施。A选项要求人们食用更多的脱脂食物，但最后一段明确指出Fat-free products of ten have high sugar levels to make them tasty，so try to avoid them，脱脂食物含有大量的糖分，应该避免食用。B选项表述不正确，文章指出：Recommended limits are 50g a day in a 2 000-calorie diet．A teaspoon is 4g．所以13 teaspoons of sugar超出了每天的限量。C选项的exercise的信息文章未涉及。排除这三个选项可以选出D，同时文章的最后一段也对D选项的内容进行了表述：More sleep will also make you less likely to crave sugar。
