你这句子有错误
应该为
It is necessary to increase the（改为“a”） number of police,because there is only （only可以省略）a few police（police重复,省略） in our cities（我们的城市,只有一个城市,用单数city）

It is necessary to increase the number of police,because there is only a few police in my city.

It's nessary to increase the amount of police,because there are only a few in my city.

It is necessary to have more policemen, because there is only a few in our city.
