Answer:
The sentence "Go to bed immediately or you can't get up early tomorrow" can be interpreted to mean that if you don't go to bed right away, you won't be able to wake up early the following morning. It suggests a consequence: if you don't take action now (going to bed immediately), you will not be able to achieve the desired goal (waking up early). In essence, it emphasizes the importance of going to bed promptly to ensure the ability to wake up early the next day.
