Question

each boy and girl; each boy and each girl

Answer 1

都是用单数三人称形式

1、each(every)+ 单数名词 + and + 单数名词,此时谓语动词用作单数,如：

Each boy and girl has come and will sign his full name before attending the ceremony.

2、each(every)+ 单数名词 + and + each(every) + 单数名词,此时谓语动词用作单数,如：

Each hour and each minute has its value.

最后,请注意,each of后的名词前须加the,如each of the soldiers（不说each of soldiers!）
