在此,我评论一下,因为问题是到达学校,强调到达,所以一楼就可以pass了,由于arrive做vi,所以五楼也可以pass了,哈哈。所以说2、3、4、6的表达正确,即He arrives at/reaches school at 8 o'clock everyday.当然,还有别的说法,也可以用个get to 这个短语,即He gets to school at 8 o'clock.
He arrives at school at 8 o 'clock every day.
He arrives at school at 8 o'clock everyday
he arrives at school at eight o'clock everyday
he reaches school at 8 o'clock everyday
