19.A Koala Isn't a BearKoalas remind people of teddy bears.They have thick fur and large ears.Their broad,flat nose makes them look cute,similar to teddy bears.In fact koalas aren't cute.They have sharp teeth and very sharp claws!Koalas are marsupials.This means the mother carries her baby in a pocket while it develops,similar to a kangaroo.The baby koala lives in its mother's pocket for the first six months of its life.
The name"koala"comes from a native Australian word that means"no drink".The koalas get almost all their water from the euclyptus(桉樹)leaves they eat.That's where they get their food too.Koalas eat only eucalyptus leaves,and only the leaves of certain eucalyptus trees.The eucalyptus trees are where the koalas live.It's also where they sleep.Koalas sleep about nineteen hours a day!
Why do they leep so much?Some people think it's because they're lazy.But koalas aren't lazy.They sleep so much because there isn't much nutrition in eucalyptus leaves.Koalas store hardly any fat,so they must save their energy.One way to do this is to move slowly and sleep a lot.
After a day of sleeping they like to move around and eat just after sunset.They live alone most of the time.Koalas are very protective of their trees.If a koala sees another koala eating in its favorite tree,it might tell the other koala to leave by"barking"at it.Koalas do"talk"to each other.Besides barks,the males make a deep grunting sound.The mothers and babies talk in soft clicking sounds.If they get scared they may scream like a baby.

分析 考拉讓人們想起泰迪熊,但它不是熊.本文向人們介紹了考拉的特點和生活習(xí)性.如在考拉成長期間媽媽會把幼崽裝在育兒袋里,考拉因為食物供給能量不足所以睡眠多,它們害怕時會像個孩子一樣尖叫.
解答 33.D 細(xì)節(jié)理解題.根據(jù)第一段的This means the mother carries her baby in a pocketwhile it develops,similar to a kangaroo.可知,這意味著在它成長期間,媽媽會在一個口袋里攜帶她的嬰兒,和袋鼠相似.所以考拉和袋鼠都把幼崽裝在育兒袋里.故選D.
34.C 細(xì)節(jié)理解題.根據(jù)第三段的They sleep so much because there isn't muchnutrition (營養(yǎng))in eucalyptus leaves.可知他們睡覺多,是因為桉樹葉沒有多少營養(yǎng).所以考拉睡眠多是因為食物供給能量不足.故選C.
35.B 細(xì)節(jié)理解題.根據(jù)最后一段的If they get scared they may scream like a baby.可知,如果害怕它們會像個孩子一樣尖叫.故選B.
點評 本文是故事類閱讀,主要考查細(xì)節(jié)理解題.在做細(xì)節(jié)理解題時,首先根據(jù)題目要求迅速在文章里找出相應(yīng)的段落、句子或短語.認(rèn)真比較選項和文中細(xì)節(jié)的區(qū)別,從而做出正確的選擇.
