英语改错题 however,some have realized the serious problem of pollutions caused by the car.
还有一个，忘了
most americans would find them hard to think what life would look like without a car.
答
however,some have realized the serious problems of pollution caused by the car.
pollution是不可数,不能用复数,problem是可数,得用复数
希望能帮到您,有一个问题，这个每句只有一个错误，就是只能改一处...........那就该pollution，因为它一定不能加复数的。most americans would find it hard to think what life would look like without a car.把them 改成it。it做形式宾语
