A: Frank, I didn't see you in the soccer game last Sunday. {#blank#}1{#/blank#}

B: Oh. I went fishing with my father in the river near our town.

A: Did you have fun?

B: {#blank#}2{#/blank#} The river was so dirty that there was no fish in it.

A: It's impossible. I went there 2 years ago. {#blank#}3{#/blank#}

B: There are many new buildings by the river now. Perhaps people living there throw litter into it.

A: That's terrible. We should do something about it.

B: We plan to write to the government to ask for more rubbish bins.

A: That would be helpful. Let's call on people not to drop waste into the water. {#blank#}4{#/blank#}

B: Good idea! I'll help to put them up this Saturday.

A: {#blank#}5{#/blank#} She cares much about the pollution.

B: Sure! I'll call her tonight.
