问题 According to Gregory Luzaich. the disadvantage of modest drinking is______.
According to the text, the "Pek Wine Steward" is______.
选项 A、a metal cone
B、a thermoelectric cooler
C、a gas injector
D、a wine preserver
答案D
解析 事实细节题。Pek Wine Steward在文中多次提到，最开始是第二段开头"The Pek Wine Steward prevents wine from spoiling by injecting argon, an inert gas, into the bottle before sealing it airtight with silicon."这可以说是对其功效及原理的一个解释—它通过在把酒用硅封盖之前注入惰性气体氩来防止酒变质，而究竟是什么东西还得看下面的论述。后面提到其发明者对市面上酒的保存工具不满意才自己研制出这种器具，第五段又讲到其具体的工作原理，也是为了使酒保鲜。那么大致可以判断是酒保鲜器具。"金属圆锥体"，第四段提到"the Pek Wine Steward, a metal cone into which a wine bottle is inserted"，但这只是其外形而已；"热电冷却器"是豪华版Pek Wine Steward包括的一个部分；"气体注入"不符合文意；所以答案选项是正确的。
