问题描述：
There have been several new events＿＿＿ to the program for the 2008Beijing Olymoic Games．
A．add B．to add
C．adding D．added
答
选D
主句是There have been several new events for the 2008Beijing Olymoic Games．
added to the program作new events 的定语
又因为new events和program是主谓关系
（主谓关系这题中指新项目是被加入北京奥运会项目中的）
所以选added
答
D
因为主句是现在完成时
表示已经发生了,所以用D
如果是正在发生,就可以用C
