问题 It is necessary that an efficient worker______his work on time.
选项 A、accomplishes
B、can accomplish
C、accomplish
D、will accomplish
答案C
解析 该题是语法结构题，考查虚拟语气的用法。虚拟语气用在主语从句中，常见的句型是It is+形容词或过去分词+主语从句。常见的形容词有essential，necessary，important，urgent等，过去分词有ordered，suggested，demanded，required等。主语从句中的谓语动词用should+动词原形或直接用动词原形。因此，根据题意和语法规则，选项C为最佳答案。
