在英文中，要求打电话给某人可以用 "call" 或 "phone" 这两个动词。

例句：

Can you please call him for me? (你能帮我打电话给他吗？)
I need to phone him about the meeting. (我需要给他打电话关于会议的事情。)

这两个动词都可以用在祈使句中，如：

Call him now. (现在给他打电话。)
Phone him at work. (在工作时给他打电话。)

如果你想表示更多的细节，可以在 "call" 或 "phone" 之后加上 "up" 或 "over"。

例句：

Can you call him up and ask him to come over? (你能给他打个电话问他能不能来这里吗？)
I'll phone him over to confirm the details. (我会给他打个电话确认细节。)

此外，你也可以在 "call" 或 "phone" 后面加上 "on"，表示通过某种方式（通常是电话或手机）打电话给某人。

例句：

Can you call him on his cell phone? (你能给他手机打电话吗？)
I'll phone him on Skype. (我会给他通过 Skype 打电话。)
