So for example, if I'm speaking in English, I have to speak grammatically differently if I'm talking about past rain, "It rained yesterday," current rain, "It is raining now," or future rain, "It will rain tomorrow."
例えば 英語を話す場合には 文法に違いが出ます 過去なら "It rained yesterday" 現在ならば "It is raining now" 未来は "It will rain tomorrow"
