中译英：你可以帮她开通一个E-mail邮箱么？

Would you please help her to get a new E-mail adress?

wuold you please help her to apply an E-mail ?

Would you please register a new E-mial adress to her?

你可以上一个外国网站看一下，其实邮箱那个，应该叫做account.
所以我的翻译是：
Would you please help her to apply/register an e-mail account?

开通不好翻译，在邮件里叫注册（register）或者申请（apply）.

Would you please help her get an E-mail adress?

Could you please get an E-mail for her?
