好英文怎么说

"How to say in English?"

If you want to ask someone how to say something in English, you can simply ask, "How do you say that in English?" or "What's the English word for that?". If you want to ask about a specific phrase or sentence, you can provide more context and say, "Can you tell me how to say this in English?" or "I don't understand what he just said, could you translate it into English?".
