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.
