可以的! how long已经足够说明是在提问时间了! 这里加了time没有语法错误! 但是有点不地道的感觉! 一般问做一件事情要多长时间,一般采用以下句式: How long does it take(time) to get to school by bus How much time does it take to get to school...
可以,how long就已经表示对时间的提问了 it takes (10 mins) to get to schoold by bus. 如果对括号里面的内容提问的话,就是how long does it take to get to school by bus. 如果要就如time的话, 就可以说成how much time does it take to get to school by bus
