説明
Use "some" when you mean an unspecified amount in a positive sentence.
For example, "I need some water." Here "I need" is the main idea, "some" means an amount that is not exact, and "water" is the thing you want. We do not say "a water" here, because "water" is uncountable.
In questions and negatives, we usually use "any": "Do you have any water?" and "I don't have any water." Japanese often leaves out this small word, but English usually needs "some" or "any" before the noun.
「some」は、量がはっきりしないときの肯定文で使います。
たとえば "I need some water." では、"I need" が「必要です」、"some" が「少しの」、"water" が「水」です。ここでは "a water" とは言いません。"water" は不可算名詞だからです。
疑問文と否定文では、ふつう "any" を使います。"Do you have any water?" と "I don't have any water." のように言います。日本語はこの区別をあまり文に出しませんが、英語では名詞の前に入れます。
例文
- I need some water. 水が少し必要です。
- We bought some apples. 私たちはリンゴをいくつか買いました。
- Do you have any milk? 牛乳はありますか。
- I don't have any money. お金がまったくありません。
- Would you like some tea? 紅茶はいかがですか。
- Is there any bread left? パンはまだ残っていますか。
よくある間違い
Japanese learners often use "some" in negative sentences and questions, for example "I don't have some money" or "Do you have some water?" In normal English, use "any" in negatives and most questions: "I don't have any money." / "Do you have any water?" Use "some" for positive sentences and polite offers like "Would you like some tea?"
日本語では「少し」をそのまま "some" で言いたくなりますが、否定文や普通の疑問文では "any" を使います。× "I don't have some money." → ○ "I don't have any money."、× "Do you have some water?" → ○ "Do you have any water?" ただし、申し出では "Would you like some tea?" のように "some" を使います。
