Quick Grammar Question.
 

How do you say your going to do something somewhere at a specific time? If the sentence was "I will read books in the library at 5:00." would it be translated as "Goji toshokan de hon wo yomimasu." or does the particle ni need to be added and should watashi wa be placed at the beginning?

EDIT: By the way, if I'm posting in the wrong place, just tell me and I'll repost where ever it is I'm supposed to post at.

You would need to place 'ni' after '5-ji'. Forget about starting the sentence with ''watashi wa". The more often you use 'watashi' or 'anata', the more foreign you will sound to the Japanese ear. Ganbatte kudasai.

Arigatoo gozaimasu.

You only need to use watashi and anata if it isn't clear without it.
