we 错了 应该改成什么 为什么~
答
It took our teacher and us three hours to work out this difficult maths problem.
take跟宾格
没有it take she/he sometime to do
是it take her/him
答
take so 多长时间 to do sth. 中间不能加主格WE,应该是宾格US就没问题
it took our teacher and us three hours to work out this difficult maths problem.
答
took 在本句中作为谓语动词。谓语后面应该是宾语，同时 宾语应用代词的宾格。we 应该为 us
答
WE改成OUR
WE是主格,OUR是宾格
答
we --us
跟our teacher 并列 在took后应用宾格
答
we 改成 us
It takes sb. to do sth.
在这里是有our teacher(s)和us一起做所以都应该是宾格
