In formal English, 'if' can be replaced by inversion: 'Had I known' = 'If I had known.' 'Were she here' = 'If she were here.' 'Should you need help' = 'If you should need help.'

在正式英语中，'if'可以用倒装替代：'Had I known' = 'If I had known'（如果我知道的话）。'Were she here' = 'If she were here'（如果她在这里）。'Should you need help' = 'If you should need help'（如果你需要帮助）。

En inglés formal, 'if' puede reemplazarse por inversión: 'Had I known' = 'If I had known.' 'Were she here' = 'If she were here.' 'Should you need help' = 'If you should need help.'

フォーマルな英語では、「if」を倒置で置き換えられます：「Had I known」=「If I had known」「Were she here」=「If she were here」「Should you need help」=「If you should need help」

격식적 영어에서 'if'는 도치로 대체할 수 있습니다: 'Had I known' = 'If I had known.' 'Were she here' = 'If she were here.' 'Should you need help' = 'If you should need help.'
