问题     The ancient Aztecs venerated the cacao tree and used its beans as a form of currency. They【C1】______the tree as a source of strength and wealth and【C2】______their god Quetzalcoatl its guardian. The Aztecs discovered that by crushing the beans into a paste and adding spices, they could make a【C3】______and nourishing drink. This drink would have been very bitter,【C4】______our chocolate drinks today. 16th century European explorers brought the drink back from their【C5】______, added sweeter flavourings, and soon it was【C6】______as an expensive luxury.
    In the 1800s, solid chocolate became popular,【C7】______the invention of moulding processes.【C8】______grinders crushed cocoa beans to a【C9】______powder that could be heated and poured into moulds,【C10】______shapes【C11】______it cooled. Dutchman Coenrad Van Houten perfected the【C12】______of cocoa butter from cocoa beans in 1825. The beans are crushed to a paste, which is【C13】______very high pressure, forming chocolate liquor and cocoa butter. The extracted butter is smoothed and【C14】______to remove any odors. In the 1880s, Rudolphe Lindt of Switzerland started adding【C15】______cocoa butter during chocolate manufacture, to make it【C16】______and glossier. Cocoa butter melts at around 97°F, which is human body temperature. That’s why chocolate melts in the mouth.
    In 1875 , Swiss Daniel Peter perfected the【C17】______of milk chocolate, which is sweeter and smoother than dark chocolate. Nestle’s recently-invented【C18】______milk was easy to mix with cocoa paste, unlike liquid milk. Cadbury’s "Dairy Milk", first【C19】______in 1905, is the UK’s most【C20】______chocolate bar. Milk chocolate is now the world’s best-selling variety.
【C20】
选项 A、popular
B、unpopular
C、expensive
D、inexpensive
答案A
解析 篇章题。上下文理解题。本段讲巧克力发展的第三个阶段——牛奶巧克力。最后一句话总结了牛奶巧克力的发展情况——世界上销量最好。选项popular意为“受欢迎的，普及的，流行的”，如：She is a populargirl．她是一个招人喜欢的姑娘。用于此处为“最受欢迎的巧克力”，符合上下文，也符合整篇文章的主题，因此，为正确答案。unpopular为popular的反义词，如不受欢迎销量就不可能那么好，因此，与上下文抵触。expensive“昂贵”，inexpensive“便宜”，此两选项与价格相关，本句乃至整段都没有提及价格的问题，因此，与题意无关，不能选。
