down go 还是 go down

1. She ran across the field after it, and fortunately was just in time to see it pop down a large rabbit-hole under the hedge.

2. In another moment down went Alice after it, never once considering how in the world she was to get out again.

老师，pop 在文中作动词用吗? down go 还是 go down? 为何如此，强调吗？

网友应该可以从see sb do sth结构中判断出pop为不带to 的不定式。不该提问这个问题。即便有问题，查一下词典不就解决了吗？pop作为动词，词义之一就是move quickly. pop down a large rabbit-hole. 一下子钻进一个非常大的兔洞。

In another moment down went Alice after it, never once considering how in the world she was to get out again.

这是倒装句。名词主语+不及物动词+方位状语的句子，假如需要强调主语，则将方位状语前置，同时将主语后移至谓语动词之后，构成完全倒装句。

译文：一会儿之后，爱丽丝跟着钻进了进来，压根没考虑她将如何出来。
