she goes school at 6:30---?--every morning.中间为什么不填?

she goes school at 6:30___?__every morning.中间为什么不填?

英语中作时间状语的短语前通常要加in, on, at, for等介词.例如：
I get up at six o’clock in the morning. 我早上六点钟起床.
但是,由every, each等构成的短语用作时间状语时,其前不用介词.例如：
Do you do morning exercises every day? 你们每天做早操吗?
They go to school by bike each day. 他们每天骑自行车去上学.
你这个句子,前面也不对,正确的应该是：
She gose to school at 6:30 every moring.
go是不及物动词,不能直接跟宾语的.
