used to 怎么填进去?

" How do you often go to school " 你经常怎样上学?
" I (used to ) take a bus,but now I (go to school by )walking.
我过去常常乘坐公交车,但是现在我走路上学.
【公益慈善翻译团】真诚为你解答!不是。。第二个空也用。。used to用进去、、我明白了，这道题的关键是区分used to（过去常常做某事）和get used to do something. (习惯于做某事。） 所以这句话是： " I (used to) take a bust, but now I ( have got used to go to school by) walking.我过去常常乘坐公交车上学，但是现在我已经习惯了步行上学。have got used to do (现在完成时，表示现在已经习惯了做某事。）有没有am used to 的用法有的，be used to do something, 习惯于做某事。例如：I am used to get up early in the morning. 我习惯了早上早起。
