Given that many people's moods (情绪)are regulated by the chemical action of chocolate, it was probably only a matter of time before somebody made the chocolate shop similar to a drugstore of Chinese medicine. Looking like a setting from the film Charlie&the Chocolate Factory, Singapore's Chocolate Research Facility (CRF) has over 100 varieties of chocolates, its founder is Chris Lee who grew up at his parents' comer store with one handalmost always in the jar of sweets.

    If the CRF seems to be a smart idea, that's because Lee is not merely a seasoned salesperson but also head of marketing department that has business relations with big names such as Levi's and Sony. That idea surely results in the imagination at work when it comes to making different flavored (味道) chocolates.

    The CRF's produce is “green”, made within the country and divided into 10 lines, with the Alcohol Series being the most popular. The exotic Series—with Sichuan pepper, red bean(豆), cheese and other flavors—also does well and is fun to taste. And for chocolate snobs, who think that they have a better knowledge of chocolate than others, the Connisseur Series uses cocoa beans from Togo, Cuba, Venezuela, and Ghana, among others.

共享经济作为一个新兴产业，让越来越多的人们体验到共享模式的便利性。小明关注时政，收集到关于共享经济相关信息：继共享单车迅速占领城市街头之后，近日共享充电宝、共享篮球、共享雨伞相继登场。然而，新业态的出现带来了新的问题：共享物品随意损坏谁来负责？共享服务从业者的资质和服务的质量谁来保证？进入共享平台的相关资金如何保障？如何在共享经济发展过程中保护人民的合法权益呢？同学们议论纷纷，并提出解决方案：

方案一：共享经济需要制定切实可行的法律法规来规范相关市场经济主体的行为。

方案二：共享经济需要加强诚信建设，形成讲公德，讲文明的道德风尚。
