Question

On every side of the road were green fields and some farmhouses.改错
这句话有几个错误啊?

Answer 1

两个错误：1 every ‘指三者/三者以上’改为 each / either ,因为road‘路’ 只有两边.
2.were 改为was 因为each/ either 修饰名词作主语时,谓语动词用单数.故正确的句子是：
On each side of the road was green fields and some farmhouses.
/
On either side of the road was green fields and some farmhouses.
