    The largest animal ever to live on Earth is the blue whale（鲸鱼）. It weighs(重) about 80 tons-more than 24 big elephants. It is more than 30 metres long. A new baby whale weighs as much as a big elephant. Cats won't die if they fall off very high places because they can turn themselves up the right way so as to keep their bodies safe. One cat fell off 32 floors onto the street, but it was just hurt a little. A bear can run as fast as a horse.  A new-born panda is smaller than a mouse and weighs about 100 grams.  Elephants are the most careful animals in their love. A male（雄性） elephant may show his lady love for up to three years until the female(雌性) elephant takes his love. They often show their love by touching each other's body. Usually, wolves do not hurt people. For years a Canadian newspaper says that they would give anyone a lot of money if he or she could show that a wolf could hurt a person. But nobody could do that. Wolves do not usually go together though（尽管） they may do this in winter and they only hurt people at an unusual time.
