如果要在此句中加both,应该加在哪？请解释

The children are both English.
Both of the children are English.
both 放在实义动词之前,be动词之后
e.g. We both like English.
还有both...and的结构
e.g. Both Lucy and Lily are English.

Both children are English.
The children are both English.

加在 the children are 后面
both 放在实意动词之前 / 助动词或be动词之后

The children are both English.
或Both of the children are English.

The children are both English.
或Both of the children are English

The children are both English.
Both of the children are English.
