GMAT Argument 7重新选题
写作题目
收起The following appeared in the health section of a magazine on trends and lifestyles:
“People who use the artificial sweetener aspartame are better off consuming sugar, since aspartame can actually contribute to weight gain rather than weight loss. For example, high levels of aspartame have been shown to trigger a craving for food by depleting the brain of a chemical that registers satiety, or the sense of being full. Furthermore, studies suggest that sugars, if consumed after at least 45 minutes of continuous exercise, actually enhance the body’s ability to burn fat. Consequently, those who drink aspartame-sweetened juices after exercise will also lose this calorie-burning benefit. Thus it appears that people consuming aspartame rather than sugar are unlikely to achieve their dietary goals.”
Discuss how well reasoned you find this argument. In your discussion be sure to analyze the line of reasoning and the use of evidence in the argument. For example, you may need to consider what questionable assumptions underlie the thinking and what alternative explanations or counterexamples might weaken the conclusion. You can also discuss what sort of evidence would strengthen or refute the argument, what changes in the argument would make it more logically sound, and what, if anything, would help you better evaluate its conclusion.

吃人工糖的人最好改吃蔗糖。因为糖精确实可导致增重而不是减重。比如,高浓度的糖精可通过消耗让大脑产生饱的感觉的化学物质来触发对食物的渴求。进一步地,研究显示,如果在连续运动至少45分钟后消耗糖,可提高身体燃烧脂肪的能力。因此,在运动后喝糖精做甜味剂的果汁的人将失去消耗卡路里的效果。因此食用人造糖精的人比吃蔗糖的人更不容易达到他们的减肥目的。
