根源”。答案：B11．解析：考查动词辨析。addto意为“增加”，即教授认为杯子本身不会增加咖啡的质量。故答案选D。increase一般表示具体数量上的增加；expand意为“扩大，增加，增加(尺码、数量或重要性)”；extend意为“使伸长，扩大，扩展”，均不符合题意，故排解。答案：D12．解析：考查介词短语辨析。inmostcases意为“在大部分状况下”，与本句中的“insomecases”相呼应。答案：B13．解析：考查动词辨析。依据语境可知，此处指“我们所喝的咖啡”，what引导宾语从句，在从句中作宾语，指代咖啡。答案：A14．解析：考查副词辨析。选择咖啡杯是有意识地选择。答案：C15．解析：考查动词辨析。自己已经选择了自认为是最好的杯子，选好之后还要端详别人的杯子。eye用作动词，意为“凝视，端详，细看”，符合语境。suspect一般不用于进行时，意为“怀疑”；envy意为“嫉妒”；consider意为“考虑”，均不符合语
