Yes/No で答えられる疑問文
ここまでの表を見てお気づきでしょうか？
シンプルに “Yes/No” で答えられる疑問文を作るのはとても簡単で、肯定文の主語と動詞をひっくり返すだけでできます。
例：
肯定文:They are Chinese.
疑問文:Are they Chinese?
肯定文: She was a nurse three years ago.
疑問文: Was she a nurse three years ago?
この疑問文の答えはこうなります。
肯定 (Yes) の答え: Yes, they are (Yes, they’re).
否定 (No) の答え: No, they are not (No, they’re not or No, they aren’t).
肯定 (Yes) の答え: Yes, she was.
否定 (No) の答え: No, she was not (No, she wasn’t).
注意： 質問に答える時に ‘you’ を ‘I’ に変えるのをお忘れなく。
疑問文: Are you a dog lover?
肯定 (Yes) の答え: Yes, I am.
否定 (No) の答え: No. I am not (No, I’m not).
