(Does # 1 mean #1-1 or #1-2? Does 'get' mean 'go'? What is the meaning of 'get along with'?)
2. Drivers sometimes can't see you.
2-1. Drivers can't sometimes see you.
(Is 2-1 wrong?)
3. Bikes are vehicles, just like cars and trucks.
3-1. Bikes are vehicles, like just cars and trucks.
(Are both OK?)
4. Look back and watch out for vehicles.
4-1. Look back and be careful about vehicles.

(Are the three all the same?)
5. Keep down close to the floor.
(Keep is an intransitive verb. Down is an adverb. Close to is a prepositional phrase. The floor is a noun phrase.
Are the above right? What is the meaning of 'keep' in this sentence?)
6. NEVER re-enter a burning building.
6-1. NEVER reenter a burning building.
6-2. NEVER re-enter a building which is burning.
(Can we use both 're-enter' and ' reenter'? Does 6-2 is also grammatical?)

All three essentially mean the same thing. To "get along with" is an idiomatic expression, not always explainable! Here are a good website to help you with idioms:

2. Drivers sometimes can't see you.
2-1. Drivers can't sometimes see you.
(Is 2-1 wrong?) 2 is better than 2-1; even better would be this: Sometimes drivers can't see you.
3. Only 3 is correct; 3-1 is not used.
4. All three are about the same, but 4 is the one most commonly used.
5. Keep down close to the floor.
(Keep is an intransitive verb. Down is an adverb. Close to is a prepositional phrase. The floor is a noun phrase.
Are the above right? What is the meaning of 'keep' in this sentence?)
Almost all are correct; "close" is also an adverb; "to" is the preposition; in addition to being a noun, "floor" is also the object of the preposition "to." In this sentence, "keep" means "stay."
6. NEVER re-enter a burning building.
6-1. NEVER reenter a burning building.
6-2. NEVER re-enter a building which is burning.
(Can we use both 're-enter' and ' reenter'? Does 6-2 is also grammatical?)
All three are fine; I've seen both "re-enter" and "reenter" but I think the one with the hyphen helps people read the word correctly the first time!
=)
1. #1 can be interpreted to mean both #1-1 and #1-2. It suggests that without rules, people cannot get along with others.
In #1-1, 'go' can be a rough substitute for 'get,' but 'get' in this context means to establish or maintain a harmonious relationship or communicate effectively with others. So "get along with" means to have a positive and cooperative relationship.
2. #2-1 is grammatically incorrect. The correct sentence is "Drivers sometimes can't see you." The placement of the adverb "sometimes" before the auxiliary verb "can't" is the correct structure in this case.
3. Both #3 and #3-1 are acceptable. They convey the same message that bikes are vehicles, just like cars and trucks.
4. #4-1 and #4-2 are similar and convey the same meaning. "Be careful about" and "look out for" are both expressions indicating vigilance and caution regarding potential dangers such as vehicles. The only difference is the phrasing used.
5. Your analysis of the sentence is correct. "Keep" is an intransitive verb, while "down" is an adverb that modifies the verb. "Close to the floor" is a prepositional phrase that provides additional information about where or how to keep down. In this context, "keep" means to stay or remain in a lower position.
6. Both "re-enter" and "reenter" can be used interchangeably, so both #6 and #6-1 are correct. However, #6-2 is not grammatically correct. The correct sentence would be "NEVER re-enter a building that is burning."
