问题补充：

Beijing announced on Sunday that the date for events the 40th anniversary of the normalization of China-Japan relations would be “adjusted to an appropriate time”.

A. marked

B. marking

C. having marked

D. to be marked

答案：

A. marked

(答案→)B. marking

C. having marked

D. to be marked

解析：考查非谓语动词。句中making the 40th anniversary of the normalization of China-Japan relations作定语，修饰名词events，mark与events之间为主动关系，故用现在分词。句意：北京政府周日宣布纪念中日关系正常化40周年的活动日期会被调整到一个合适的时机

故B正确。
