英语改错题,三处错误
At present,about 30% of the city'S families have computers.
Besides,many village people are more and more interested computers.
and some of whom even have bought computers .

At present,about 30% of the (city) families have computers.(这里不用所有格的,城市家庭就是city family)
Besides,many village people are more and more interested (in) computers.
And some of (them) even have bought computers .
改的地方加上了括号,另外最后那句的and应该是大写,不过我估计是你输入的时候打错了,所以没改.
