In complex sentences, tenses must relate logically: 'I knew that she was coming' (backshift). But general truths don't backshift: 'He explained that water boils at 100°C.' Future in past: 'would,' 'was going to.'

在复合句中，时态必须逻辑关联：'I knew that she was coming'（时态后移）。但普遍真理不后移：'He explained that water boils at 100°C.' 过去将来时用'would'或'was going to.'

En oraciones complejas, los tiempos deben relacionarse lógicamente: 'I knew that she was coming' (retroceso). Pero las verdades generales no retroceden: 'He explained that water boils at 100°C.' Futuro en pasado: 'would,' 'was going to.'

複文では、時制は論理的に関連している必要があります：「I knew that she was coming」（時制の後退）。しかし一般的真理は後退しません：「He explained that water boils at 100°C.」過去における未来：「would」「was going to」。

복합문에서 시제는 논리적으로 연관되어야 합니다: 'I knew that she was coming' (시제 후퇴). 하지만 일반적 진리는 시제가 후퇴하지 않습니다: 'He explained that water boils at 100°C.' 과거 시점의 미래: 'would,' 'was going to.'
