Nowadays square dancing has been becoming
popular. Some public places are usually {#blank#}1{#/blank#} (crowd) with dancers,
especially in the morning and evening.
We all agree that square dancing is a good
way to keep healthy, {#blank#}2{#/blank#} for the old. {#blank#}3{#/blank#}, it is money-saving.
But it also causes noise {#blank#}4{#/blank#} (pollute). Many people suffer from the
noise {#blank#}5{#/blank#} by the loud music. They can't work, study {#blank#}6{#/blank#} sleep
well. They feel very angry and some {#blank#}7{#/blank#} argue with the dancers.
In my opinion, the dancers should turn

build {#blank#}9{#/blank#} (many) public places for them, such as squares and parks.
People can have fun dancing without {#blank#}10{#/blank#} (disturb) others.
