否則

In a sentence

• 请完成任务，否则后果自负。

  Please complete the task, otherwise bear the consequences.

  Here, '否则' serves as a conjunction introducing the alternative negative condition if the preceding action is not carried out.

• 尽快出发，否则我们会错过火车。

  Start quickly; otherwise, we'll miss the train.

  In this case, '否则' links the necessity of the preceding clause to the negative outcome mentioned after it.

• 你需要服从规则，否则你会受到处罚。

  You need to adhere to the rules, otherwise you will face penalties.

  '否则' is used to indicate the result of not complying with the required action or condition in the initial clause.
