是否用英语怎么说

"Do you speak English?" is how you ask someone if they are fluent in the English language. This question is a simple and direct way to inquire about someone's language abilities, especially when conducting business or communication with inpiduals from English-speaking countries. The answer could be a simple "Yes, I do" or "No, I don't", depending on the person's proficiency in English. It's important to note that understanding someone's level of English can also help facilitate effective communication and avoid potential misunderstandings.
