资料：The hop flower has been used in beer-making at least since the eighth century. Traditionally it was a preservative, but it also imparts flavor. To some, the taste is bitter and unpalatable, and thus many brewers use only minimal amounts. But, depending on variety, growing conditions, and other factors, hops can impart a range of flavors that connoisseurs say rivals that of wine grapes. Starting in the nineteen-seventies, small brewers on the West Coast began dramatically upping the amount of hops in their brews. One of their most popular products was the India pale ale, or L.P.A., a brew that has been around since the late eighteenth century. The story goes that necessity drove the British to add large quantities of hops in order to preserve the beer they shipped to India, to quench the thirst of the Sahibs managing the Empire there.Over the past decade, varieties once thought of as boutique beers, such as L.P.A.s, have exploded in the United States, thanks to the locavore movement. Craft brewing is now doubling in sales, by volume, every five years, today, craft-beer make up twenty-one percent of the beer market, and twelve percent of the volume. The Brewers Association, a craft-brewing trade group, expects craft beers to have a fifty-per-cent market share in a decade. Since craft brewers use about ten times more hops than megabrewers, the trend has been a bonanza for Hopsteiner and the other big hops companies. But while an emphasis on brewers to come up with new beer, which, in turn, leads to a hunt for new hops varieties.Which of the following best expresses the author’s main point?

C：The rise of locavore movement makes craft brewing a new trend in the United States.
D：Megabrewers are losing market share because people are searching for the unpalatable taste of hop flower.

本题考查的是主旨大意。 【关键词】author’ main point 【主题句】第一段第1句The hop flower has been used in beer-making at least since the eighth century. Traditionally it was a preservative, but it also imparts flavor.（至少从8世纪开始，啤酒花就被应用在啤酒酿造中。传统上，啤酒花是一种防腐剂，但是它也能传递味道。） 【解析】本题问“以下哪项最好诠释了作者的主要观点？”。主旨题在解题时一般看首段，找到作者论述的重点，即hop flower（啤酒花）。A选项“啤酒花应用在啤酒酿造已有几十年”。根据主题句，啤酒花从8世纪开始使用，几十年和时间不符，排除该选项。B选项“不同种类的啤酒花能带来不同口味的啤酒”，和第一段“hops can impart a range of flavors”表述一致，且和本文中心一致。C、D两项均为局部信息，不能作为全文主旨。
