求错因以及正确原因.

答案

第一题 spend on sth 是搭配,所以用 on which
第二题 or so 也是固定搭配,大约的意思,楼主选A的话 就是把or 当连词了,但是My parents will move back into town in later 是不用in的
第三题get down to 也是固定搭配,去做什么事情.B 是脱离,出去的意思,C是回到什么去,D是克服
第四题中,就前半句来说,among 和of 都能选,但是among相当于one of,而不能说among all,总体来讲如果不是做语法题,of和 among区别不大,一般区别在数量上,of不限制数量,among三个或以上
不知道说清楚没,可以追问
