1. He is on the train. He is sitting in the seat. He takes a nap.

2. He is on the train. He is sitting in the seat. He goes to sleep.
3. He is on the train. He is sitting in the seat. He goes to bed.
4. He is on the train. He is sitting in the seat. He begins/starts to sleep.
---------------------------------------------------
Can we use all the expressions? Are they the same? Actually there is no bed on the train. He feels sleepy and sleeps in the seat.

1 and 2 are fine, but I wouldn’t use 3 or 4.

Thank you.

What does 'go to sleep' mean?
Does it mean that he goes to a place to sleep? Or does he fall asleep in the same place?

1. He goes to a place to sleep.
2. He fell asleep.

It can mean either one.

He went to his bedroom when he was ready to go to sleep. (intentional)
He falls asleep during class sometimes. (unintentional)

In the given scenarios, while all the expressions convey the idea that he is sleeping while sitting in his seat on the train, there are subtle differences in meaning.

1. "He takes a nap." - This implies that he is intentionally taking a short sleep, perhaps to rest or relax.

2. "He goes to sleep." - This suggests that he is planning to sleep for a longer duration, indicating a more intentional and prolonged sleep.

3. "He goes to bed." - This expression is not suitable in this context, as there is no bed on the train. It would be more appropriate to say he "goes to sleep" or "takes a nap."

4. "He begins/starts to sleep." - This implies that he is just starting to fall asleep. It conveys the idea that he was awake, but now he is transitioning into a sleeping state.

Considering that there is no bed on the train in the given scenario and he is sleeping in his seat, it would be more accurate to use the expressions "he takes a nap" or "he goes to sleep" to describe his action.
