一个简单的倒装句
我造了个句子，意思是：羊就进来了，我写的是in came a group of sheep when it is rain，如果我要写羊进屋了，这个house放在哪里，如果是下雨了人进来了这么写对不对，in they came when it is rain，麻烦给看下

答案

倒装句:
一下雨,羊就进来了:
In came a group of sheep as soon as it started to rain.
加上house的话:
Into the house came a group of sheep as soon as it started to rain.
一下雨,人就进来了:
In came a group of people as soon as it started to rain.
用they代替人的话:
In they came,as soon as it started to rain.
