Mr Black isn't here.She's gone to Guangzhou?
Guangzhou?I（）she ( ） gone to Beijing.
正确选项中两个空分别是thought had 为什么要用过去进行时,
是过去完成时.

因为前面问题中用了完成时,She's gone to Guangzhou? 这里She's是She has的缩写 ,所以后面也要用完成时,而他做去北京是过去的事,所以还要用过去式,所以最终就要用过去完成时.
再问：为什么是过去的事，从哪儿可以看出来？而且，为什么不能用现在完成时呢。。。。。
再答：从第一句话就可以看出来啊Mr Black isn't here. She's gone to Guangzhou? 说明Mr Black 在说话这个时间没在这，在说话这个时间之前就去了广州，在说话这个时间之前当然就是过去了。所以必须要用过去完成而不是现在完成
