Ding Ling Ding Ling "-Hey, who's it," "Doctor Dong, I'm a little yellow croaker, something happened to the fish," "What's the matter?" "All of our fish families have moved from the South China Sea to the East China Sea," "Why?" "Without further ado, come over quickly!

Good. I hurriedly put down my ** and came to Donghai Hospital.

I came to the little yellow croaker and gave it painkillers, and he cried and said to me, "Doctor Dong, those people are so hateful, they put the remaining lunch boxes and residues on the boat into the Yellow Sea, and many fish rushed to eat, and some of the fish were made because they drank the unclean water in the sea." "Oh.

Then I came to the most poor little herring, whose eyes were swollen with tears, because its parents had eaten too much, and it was so dead that it died. I couldn't bear it anymore, and my eyes were shining with tears. Then many of the fish cried to me about their pain.

The shark said angrily: "Since human beings do not protect the environment so much, then let them eat poisoned fish and poison them," "No——, it should not be like this, it is not something that can be replaced by death, but to let human beings know how to protect the environment, otherwise, human beings will not realize their mistakes, but continue to be wrong," "Yes, what the little yellow croaker said is reasonable, shark brother, don't be so impulsive." In this way, everyone went back, and suddenly the East China Sea became quiet!

Catcher: One day, on a sunny day, three children meet up to catch fish in the creek behind the house. The air in the bamboo forest is fresh, the trees are shady, and a few geese will fly by from time to time.

The birds sing briskly in the trees, and in their eyes, the bamboo forest is their paradise. As I walked along the path, I saw a meandering river in the distance. It's here!

Several children came to the stream with great interest and looked intently at the small fish in the stream. These little fish come in all sorts of shapes and shapes. The three children sat on the rocks by the stream and began to fish.

The eldest child holds a fishing net and carefully nets a grouperfish. Again and again, the little fish dodged the child's net. After a while, "the net has arrived!"

The net has arrived! I caught a grouper! The older child shouted happily.

The other two children hugged happily. There was a lot of laughter from children in the bamboo forest. The children continued their efforts and netted a second small fish.

They carefully netted a small yellow fish. Suddenly, there was silence as the children watched intently as the fish swam. Suddenly, there was a cry, and the three children shouted happily:

That's great! We've caught a little yellow croaker! The sun was setting in the west, and the bamboo forest was filled with the joyful laughter of children.

(1) The small yellow croaker completes the long-distance "trip" by swimming with the swing of the trunk and tail and the coordination of the fins.

2) Fish breathe with gills, the main part of which is the gill filament, which is densely covered with capillaries, which facilitates gas exchange during respiration

So the answer is: (1) torso; Tail; Fins.

2) gill filaments; Capillary.
