It took us one week to finish the work.
问题描述:
It took us one week to finish the work.
我们花费了一周的时间完成了这项工作.
It是做什么的啊?
改成
we took one week to finish the work.
为什么不能we took one
答
it 在这里代替 to finish the work,因为主语是to finish the work太长,所以用代替.还有句子比如:我步行到那儿花费了多长时间,it took me a long time to walk there.句型就是:it take sb sometime to do sth...
