People will work tree days a week.(对画线部分提问)

问题描述:

People will work tree days a week.(对画线部分提问)
_____ _____ _____ people work a week?
原因
忘了,画线部分是tree days

__How___ __long___ _will____ people work a week?
原因 一段时间用how long提问.时态不变是将来时不是how often?你看你的问句中还有个a week! 如果对three days a week 划线提问,就用how often再说你的原句本来就用了将来时,说明动作还没发生看补充你的原句本来就用了将来时,说明动作还没发生,即使对three days a week 划线提问,也用how long可是书上就有这一句,老师好像说过用how often啊还是how long !如果你的句子是这样的Peoplework tree days a week(句中没有will)就用how often do people work a week?
