阅读短文，判断对（T）错（F）。
The whale is the biggest animal in the sea.Some whales can be 30 meters long,but some whales are only 1 meters long. The whales live in the water,and they can swim,they look like fish ,so we call them fish.But they are very different from the fish .The little whales drink their mothers’ milk, they are mammals(哺乳动物）.Now the people kill（杀） many whales every year.The number of the whales is less and less(越来越少）. So we should protect the whales.
