英語陳述句變為否定句有一套簡單的口訣:
1. 肯定句變否定句,簡單口訣要牢記:
去掉be或情態動詞,
加not或do加not,
陳述句中用some,
否定句中用any。
2. 對於實意動詞,使用do、does、did輔助構成否定句:
單數主語:didn't + 動詞原形
複數主語或不可數名詞:don't + 動詞原形
過去式:didn't + 動詞原形
以下是一些實例:
1. I am a student. (我是學生。)
變為否定句:I am not a student.
2. She likes apples. (她喜歡蘋果。)
變為否定句:She doesn't like apples.
3. We want to go home. (我們想回家。)
變為否定句:We don't want to go home.
4. They played football yesterday. (他們昨天踢足球了。)
變為否定句:They didn't play football yesterday.
需要注意的是,當陳述句中含有助動詞、情態動詞時,只需在這些詞前加not即可。如:
1. He can speak English. (他會說英語。)
變為否定句:He can't speak English.
2. You should finish your homework. (你應該完成作業。)
變為否定句:You shouldn't finish your homework.
3. Tom might go to the park. (湯姆可能會去公園。)
變為否定句:Tom might not go to the park.
