Can we use #5 and #6 as well?

1 and 2 mean the same thing. 2 has unneeded words in it. The prepositional phrase "to school" is telling WHERE, modifying "come."

3 and 4 are the same as 1 and 2.

5 wouldn't be used.

6 is fine.

To determine if sentence 1 means sentence 2, and if sentence 3 means sentence 4, we need to analyze the meaning of each sentence individually.

1. You should wear your uniform to school.
2. You should wear your uniform when you come to school.

Sentence 1 suggests that the act of wearing the uniform is specifically done for the purpose of going to school. It implies that the person wearing the uniform should put it on before going to school.

Sentence 2 implies that the person should wear the uniform once they have arrived at school. It does not necessarily specify when the person should put the uniform on, as it focuses more on the act of wearing it while at school.

So, sentence 1 suggests wearing the uniform prior to going to school, whereas sentence 2 implies wearing the uniform after arriving at school.

Now let's analyze sentences 3 and 4.

3. You should wear your uniform at school.
4. You should wear your uniform when you are at school.

Similar to the previous pair, sentence 3 suggests wearing the uniform while present at school. It does not specify the exact time of putting it on or taking it off.

Sentence 4 emphasizes that the person should wear the uniform only when they are physically present at school. It clarifies that the act of wearing the uniform should be exclusive to being at school.

Regarding the part of speech of "to school" in sentence 1, it functions as a prepositional phrase modifying the verb "wear." It specifies the destination or purpose of wearing the uniform. In this case, it emphasizes that the uniform should be worn with the intention of going to school.

Overall, "to school" in sentence 1 modifies the verb "wear," whereas in sentence 2, "when you come to school" modifies the verb "wear" and specifies the time or condition when the uniform should be worn.
