The best way is to keep pet fish out 【小题7】 rivers and lakes in the first place. People should give unwanted fish back to pet stores, where pet fish can 【小题8】 (leave).

The pileated woodpecker (红冠黑啄木鸟) is one of the 【小题1】 (large) woodpecker species in North America and its look is unmistakable-a large black bird with white on each side of its neck and a red crest on its head. When it flies, white flashes are visible under its 【小题2】 (wing).
