前两句提问是对的.
jump off是固定搭配,是跳下来是意思.还有像get off the bus,下车.那fly over也可以当做一个短语啊？Jump这一句的提问应该是怎么样的提问啊？off thr wall:what are the children jumping? 第二个:what are the children jumping off?off thr wall:what are the children jumping? 第二个:what are the children jumping off?我觉得是不是Where are the children jumping? What are the children jumping off? 不带介词应该用Where提问，但是读起来怪怪的这个提问本身就有问题这个提问本身就有问题
