Question

Birds live in trees. But do you know that some frogs live in trees, too?

Yesterday my cousin told me something about tree frogs.

Tree frogs are not easy to find. They can change their colours. On green leaves, they stay green. On a brown tree, they turn brown. Some tree frogs can change from green to gold or blue.

Tree frogs have legs and big feet. They have sticky(黏的) pads on the end of their toes. These toe pads keep them from falling from the trees.

Tree frogs can be all different colours. Their eyes are of different colours, too. Some have green eyes, and some have grey eyes. Some frogs’ eyes are gold, and some are bright red. The sounds they make are different, too. One frog makes a sound like dog barking（狗叫）. Another frog makes a loud noise like a snore（打呼噜）. There is even a frog that whistles(口哨)!
