问题 After two years he received the certificate of the college for ______ in chemistry.

选项 A、proficiency
B、diversion
C、immersion
D、involvement

答案 A

解析 名词辨义。这四个选项都是名词形式,proficiency表示“熟练,精通(常跟介词in连用)”;di version表示“转移,转换,牵制”;immersion意指“沉浸,浸没;专心,陷入”;involvement表示“连累,包含”。根据句意,因为精通化学知识,他才拿到学历证书,所以A)项符合题目要求。
