问题补充：

In view of the global financial crisis, every possible means to stimulate the economic development in China.

A. have tried

B. have been tried

C. has tried

D. has been tried

答案：

A. have tried

B. have been tried

C. has tried

(答案→)D. has been tried

解析：选D考查主谓一致和语态。句意：由于全球金融危机，中国已经采取每一种可能的方法来刺激经济的发展。every possible means作主语，此处means是单数可数名词，故谓语用单数，再由句意知需用被动语态。
