1.B 2.A 3.D 【解析】 【原文】 Food is created in various ways, sometimes by accident or by experimentation. Here’s how a fun product was invented. In 1930, Ruth and Kenneth Wakefield opened a restaurant on an old road between Boston and Cape Cod in Massachusetts. They named it the Toll House Inn. Ruth was an expert cook, and the inn became famous for its desserts. Many sources claim Ruth invented her chocolate chip cookie by accident. But she often experimented with recipes to please her guests. One time, she decided to add chocolate to her popular butter cookies. She told a Boston newspaper reporter that she was deliberately “trying to give her guests something different”. Using a tool, she broke a semi-sweet chocolate bar into small pieces and mixed them with egg, milk and flour. When she took the cookies from the oven, the chocolate hadn’t melted into the flour mixture. Guests loved Ruth’s new Toll House Chocolate Cookies. The recipe soon appeared in a Boston newspaper. Ruth added it to the 1938 edition of her cookbook. The recipe called for two Nestlé semi-sweet chocolate bars to be “cut in pieces the size of a pea”. The cookies became so popular that Nestlé’s sales increased greatly. The company began carving lines into its chocolate bars to make them easier to break. It even printed Ruth’s recipe on the wrapper. Later, Nestlé created the semi-sweet chocolate chip. The recipe still appears on every bag. Accident or not, Ruth Wakefield created America’s most popular cookie. Questions: Where did Ruth invent the chocolate cookie? How was Ruth’s chocolate cookie created? What did Ruth do to her recipe for chocolate cookies?
