Once upon a time, three fish lived in a river. Their         (名字) were Thoughtful,Very Thoughtful,and Thoughtless.
One day, They left the wild country where no humans lived. They swam         (几个) miles down the river to live near a town.
After just two days, Very Thoughtful said to the other two, “We’re taking a(n)      (风险) to live here. I think we should        （返回) to the wild country.”
But the other two fish       (似乎) to be used to living here. They said, “Come on, Very Thoughtful, there was no        (危险) like you thought.”
One day, while they were looking for food, Very Thoughtful saw a fisherman’s net(网). He                    (告诉) the other two in time, or they might be caught by the net.
“You saved our          (生命), Very Thoughtful!” they both cried. “Now we                          (理解)you and we’d like to go back with you. We all         (想念) the wild country.” That day, they swam back to their old home and lived safely ever after.
