大海的英语该怎么说呢

"大海" is "the sea" in English. You can also use the phrase "the ocean" to refer to the vast body of saltwater that covers a majority of the Earth's surface. Both "the sea" and "the ocean" can be used to refer to the same thing, but "the ocean" is generally used to refer to the entire body of saltwater that covers the Earth, while "the sea" can be used to refer to a smaller body of saltwater that is part of the ocean. For example, you might say "I went to the beach and played in the sea" or "I took a cruise across the ocean."
