参考答案

正确答案：A
解析：本题考点为形容词与介词的搭配。英语中有少数形容词比较级不用连词than。这类形容词有 superior(优于)，inferior(低于)，senior(年长于)，junior(年幼于)等，他们后面接to，而不是than。例如： His strength is superior to mine．A teacher's knowledge shouldn't be inferior to his students．He was 8 years senior to Anna，and their marriage broke up after their son was born．
