it is impossible to make more than the wildest guess at how many they kill
问题描述：
it is impossible to make more than the wildest guess at how many they kill
看参考书书上解释how many they kill 做at 的宾语.那么就是说guess在这里是做动词讲,而非名词.因此不解为何guess在这做名词.请尽量详细.
答
at前面不一定是动词,即介词前面不一定是动词的,at在这里有点类似about的意思,这样一来你可以理解为关于how many they kill的猜测,而且看前面的make已经是动词,后面的guess是名词才对.
