市民们 citizens前加不加the

看语境，如果表示特指，需要加“the”，如果泛指则不需要。

例如:

The citizens were warned to be on guard against a sudden night attack.市民们得到通知,要提防夜间的突然袭击。

The article was insulting to the families of British?citizens.那篇文章侮辱了英国公民家庭。

By and large, these people are peace-loving, law-abiding?citizens.大体上，这些人都是热爱和平、遵纪守法的公民。
