问题描述:

"In South China,many people have to work by boat because water around their house."是神马意思?
对了,先说一下这是不是病句

在中国南方,由于周边被水环绕,许多人不得不坐船去工作(出行)。

在中国南方,因为水多很多人不得不乘船去工作

病句,有语法错误.纠正一下
In southern China, many people have to go to work by boat because their houses are surrounded by water.
南方,名词,应该用southern.我改的英文语法应该是没错了,但这句话意思有些难以理解,为什么房子会被水包围呢?

在中国南方一些城市,人们外出工作不得不乘船,因为房子四周都是水。

这个句子好像不太完整,感觉像没说完……
