没把… / 不把… / 别把…【méi bǎ… / bù bǎ… / bié bǎ…】

A 把 sentence is negated by putting 没, 不 or 别 in front of 把. Modal verbs such as 要, 想, 能 and 应该 go in the same place.

• × 我把作业没做完 → 我没把作业做完
• × 你把门别关上 → 你别把门关上
• × 我把这本书想看完 → 我想把这本书看完

没把 drops the 了

Something that didn't happen has no completion to mark, so the 了 goes.

• × 我没把作业做完了 → 我没把作业做完

别把 for warnings

别把 is the negative 把 you hear most in speech. A 了 at the end turns it into a warning about something that could happen by accident.

不把 for habits and attitudes

不把 says what someone doesn't do as a rule, or won't do.

Adverbs like 已经, 都 and 还 go in front of 把 too.
