2022—2023学年上学期高一年级 （英语）学科寒假作业（八） 答题时间：50分钟 I. 阅读理解 阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。 A Although it is often called the koala“bear”, this lovely animal is not actually a bear at all. It is a marsupial (有袋目哺乳动物), and like kangaroos, a female koala carries her baby in her pouch (育儿袋) for about six months. Koalas live in four states only in eastern Australia, where the eucalyptus trees they love are most plentiful. In fact, they seldom leave these trees, their sharp claws (爪子) easily keeping them high up in the air. During the day they sleep for up to 18 hours. When not asleep, they feed on eucalyptus leaves, especially at night. Koalas do not drink much water and they get most of their water from these leaves. Each animal eats a large amount for its size—about two and a half pounds of leaves a day, even storing snacks of leaves in pouches. The koala bears were widely hunted during the 1920s and 1930s and their populations decreased suddenly. Helped by reintroduction, they have reappeared over much of their former habitats, but their populations are smaller. Koalas need a lot of space—about a hundred trees per animal—which is a pressing problem, as Australia’s woodlands continue to get smaller because the trees they live on are being cut down to make farms. Also, forest fires, caused by heatwaves, are destroying the forests the koalas live in. It has been estimated (估算) that there are only 100,000 koalas left in the wild, with the lowest estimates being no more than 43,000. The koala can only eat eucalyptus leaves and lives nowhere else except Australia, so in order to survive, human effect on its limited environment must be controlled, or this attractive creature faces certain extinction. 1. What can we learn about koalas from the first three paragraphs? A. They eat most of the day. B. They feed on eucalyptus leaves. C. They belong to the bear family. D. They use the pouch to store water. 2. What caused the decrease of koala populations during the 19
