Explanation
Use "be" + "not" to make a negative sentence. In speech, we often use "isn't" and "aren't".
For example, "She isn't at home." Here "She" is the subject, "isn't" means "is not", and "at home" tells us the place. Japanese often says "彼女は家にいません", so the meaning is similar. But English must keep the be verb and add "not". Do not use "don't" with adjectives or nouns.
「be + not」で否定文を作ります。会話では "isn't" や "aren't" をよく使います。
例えば "She isn't at home." では、"She" が主語、"isn't" が "is not"、"at home" が場所です。日本語では「彼女は家にいません」と言うので意味は近いですが、英語では be 動詞を残して "not" を足します。形容詞や名詞の文では "don't" を使いません。
Examples
- I'm not tired. 私は疲れていません。
- She isn't at home. 彼女は家にいません。
- They aren't ready yet. 彼らはまだ準備ができていません。
- Are you busy now? 今、忙しいですか。
- Is this seat free? この席は空いていますか。
- We aren't late. 私たちは遅れていません。
Common Mistakes
Japanese learners often omit "be" or use "don't" with adjectives.
Wrong: "I not hungry."
Right: "I'm not hungry."
Wrong: "She doesn't happy."
Right: "She isn't happy."
Use "am/is/are + not" with "be".
