Question

With each shovel of dirt __36____ hit his back
为什么36填 that
With each shovel of dirt that hit his back,the donkey was doing something amazing.
当每一铲土落到驴背上时,它就做一件令人惊奇的事—它把土从背上甩掉并踩在上面.

Answer 1

这里--36--hit his back 是个定语从句,修饰的是dirt,是“dirt”落在了他的背上,
同时可以看出,在--36--hit his back句中,有谓语hit,宾语his back,唯独缺少主语,所以需要添加的是主语成分,答案that 作该定语从句中的主语,最合适不过了.
