The koala(考拉) is possibly one of the best known Australian animals, and is found in four states: Queensland, New South Wales, Victoria and South Australia. The word “koala” comes from an Australian aboriginal word meaning “no drink”. Sometimes people call them “koala bears” but koala is not a bear. It belongs to a special group of Australian mammals, called marsupial(有袋类). Female marsupials have a pouch where the baby animals live after they are born. Koalas have soft, thick, grey or brown fur on their backs. The fur on the stomach is white. Koala that live in the south have thicker fur than those in the north because of the cold winters, whereas the koalas in the northern part of the country live in warm to hot weather most of the year so have thinner fur. A koala has a large hairless nose and round ears. Koalas don’t have tails. Adult koalas measure between 7 and 14 kilograms. Koalas spend nearly all their time in the trees using their sharp, curved claws and long toes to climb about and to hold on to the tree branches. They sleep most of the day, and feed and move from tree to tree mainly at night. The reason koala sleep for much of the day is because their food eucalyptus(桉树) leaves are very tough so they use a lot of energy to digest. Sleeping saves energy. Eucalyptus leaves are poisonous to almost every other animal. Koalas rarely drink water; they get water from the leaves they eat. Each koala has a home range made up of several trees that they visit regularly. They normally do not visit another koala’s home trees except that a male is looking for a female to mate with. 小题1:Which of the following statements is NOT true about the name “koala bear”?
