问题    Obesity is an epidemic to some and an opportunity to others. More than two-thirds of Americans are overweight. Find a way to battle obesity, 【C1】______a huge profit might be made. On February 22nd,  2013 one pharmaceutical firm, Vivus, took a small【C2】______towards this goal. A committee advising America’ s Food and Drug Administration(FDA)recommended Vivus’ s diet drug, Qnexa.【C3】______, the pill’ s long-awaited final approval may not come until April. The announcement mostly served as a reminder of a struggle which【C4】______fat into gold.
   Medical-device and pharmaceutical companies are quite【C5】______treating the problems that come with obesity. However, they can’t help consumers【C6】______weight. Allergan, a device-maker, has tried to use its gastric bands to enter the obesity market. The band is fitted near the top of patients’ stomach, which helps them feel full【C7】______during the meal. Allergan has captured about 70% of the worldwide market for gastric bands, but sales are now【C8】______. The recession has sapped consumers’ desire for expensive surgery. Some patients have【C9】______bands removed because they slipped or proved【C10】______. In January David Pyott, Allergan’s chief executive, said he would cancel an effort to market the band for teenagers. He is now trying to convince insurers of the gastric band’ s【C11】______.
   Drug companies have had even more【C12】______than device-makers. It has been 13 years since the FDA approved a【C13】______diet pill. That drug, Roche’s Xenical, has【C14】______side-effects. The FDA rejected Vivus’s Qnexa in 2010 over【C15】______for the safety of pregnant women and the quickening of patients’ heart rates.
   However, Vivus’ s new data in 2013 apparently satisfied the FDA’ s advisory committee.
   But the agency may yet【C16】______the drug.【C17】______Qnexa is approved, it is unclear that patients will buy it. Qnexa【C18】______two medicines that are already on the market. Both medicines are generic, which means that doctors may【C19】______the existing drugs rather than Qnexa’s more expensive version. For now, it is more【C20】______to treat fat patients than to try to make them slim.
【C2】
选项 A、chance
B、progress
C、risk
D、step
答案D
解析 本题考查名词辨析。此处的句意为“2013年2月22日，Vivus制药公司朝着这个目标前进了一小步”。take a step“迈出一步，采取措施”符合题意，故D．step为正确答案。take a chance“冒险，碰运气”，take a risk“冒危险，冒风险”，根据句意排除A、C项。progress是不可数名词，且常用固定搭配为make progress“取得进步”，故排除B项。
