A bear is a wild animal. It is very strong and dangerous. It lives in the forest. Its head is big. Its neck is short but fat. Its paws are big and very strong. A bear has big clutches. Its eyes are small. Its ears are small too. Bears sleep in winter. I think bears are very clever.
Медведь - дикое животное. Он очень сильный и опасный. Он живет в лесу. Его голова большая. Его шея короткая, но толстая. Его лапы большие и очень сильные. У медведя большие когти. Его глаза маленькие. Его уши маленькие тоже. Медведи спят зимой.
Я думаю, что медведи очень умные.
