each后面跟单数还是复数，they

后面跟复数，例如：

1、Even where parents no longer live together， they each continue to be responsible for their children.即使父母不再共同生活，他们也要分别对子女负责。

2、They each received a legacy of$ 5 000.他们每人得到了5000元的遗产。

3、They each have their own email address.他们每个人都有自己的电子邮件地址。

复数，因为主语是they。

each作主语是谓语动词用单数

作同位语时，根据主语判断动词的单复数形式.

1、 They each have a book.

2、 Each of them is from China.

第一句each 为同位语，主语是they 第二句each 为主语，谓语动词是单数.
