第一,这里有具体的时间,有具体时间一般不用完成时.第二,过去完成时多用于和过去时比较,也就是说要发生在过去的过去才用过去完成时.比如:We were shocked to know that the work had been finished.第三,主句是we are happy,所以就算是要用完成时也是现在完成时.在选择时态的时候,一方面要考虑上下文的时态,一方面要注意是否虚拟语气,因为虚拟语气的时态需要倒推的.

别听其他人胡说八道，不懂别乱说我先回答你后面的问题，have been to是去过的意思，I have been to China.我去过中国。要弄清楚had been，得先弄清have been，have been表示站在现在的时间点来讲，从过去的某个时刻就开始进行的动作，一直持续到现在，还有可能继续持续到将来，举个例子：Where have you been hi...
