用法筆記
At first is almost always used to contrast an early situation with something that happened later. Common sentence patterns are 'at first ... but/but then/but after ...' or '... at first, but later/eventually/after a while ...'. If no contrast is intended, use 'first' or 'at the beginning' instead. At first cannot be followed by 'of' — for that, use 'at the beginning of'.
