车子的时速用how far提问吗,例如 it is very difficult for a person to know ___ a car is traveling how far的提问有几种回答方式 It is only 40 minutes from the centre of Beijing by underground.这句话应该如何提问?为什么?有人说：用“How far...”提问,可是How far...不是提问距离的吗? In five minutes用什么提问?how soon how far how often how long 四十英里 用什么提问 英语是不是how far how far和how long的区别如果回答是：About 5minutes' walk那提问用哪个啊? how long可对地点“多远”提问吗how far地点提问 用how soon,how long,how far提问时该怎么回答? 对“It's ten minutes' walk.”的提问应该是什么?用“How long does it take?”行吗?还是“How far is it?”老师说是how far，为什么how long不行呢？？？ how far可用于提问什么? how far、how soon、how long提问.给怎么回答 five minutes‘ walk用什么提问 how long 还是how far how long和how far的区别我的意思是当 how long和how far都对 距离/长度 提问时的区别! how often,how soon,how long,how far分别表示什么意思,分别什么时候用什么提问,请举出例子 什么时候用how long什么时候用how far?例如一道题：It's 500 metres away from here.（就划线部分提问）划线部分是500 metres____ ____is it from here? How far 的用法 关于“how”的造句.用How manyHow muchHow oldHow aboutHow longHow farHow often造句 The first aeroplane flew for 12 seconds. 提问这句话为什么要用How far提问,12 seconds 应该是指12秒并没有路程的意思吧,如果这是How far提问,要How long 提问应该怎么改这句句子呢?求解谢谢!
