单选题
A. time
B. random
C. sight
D. risk
【正确答案】
D
【答案解析】文章第一句说明电子商务彻底改变了市场的经营方式，是“利”。第二句开头就是However，见到这个词我们可能想到下文将谈到“弊”，而且空白处后面是“购买假冒或劣质商品”。at the time of的含义是“在……时候”，at random是“随意”或“随机”，不接of，而at the sight of表示“看到”，只有at risk of...比较合适，其意义是“有……的风险”。
【答案解析】空白处前面是dangers(危险或风险)，后面是“网购缺少透明度”，我们应思考哪个动词能连接obscurity和dangers。obscurity只能引发风险，不可能是prevent，而不可能是“管理”或“控制”风险，create的含义之一是“使……形成”，如the difficulty created by poverty。
【答案解析】在本句中，空白处前面的动词measure的含义是“达到某一数量或程度”，而空白处后面文字的意义是“以前在网站中宣称的”。as to：关于；prior to：在……之前；up to：多达，直到，达到，接近，取决于，是……的责任；next to：接近，紧挨着。products not measuring up to what was previously advertised in the website的意义是“产品质量没达到网站广告先前宣称的标准”。
