5．Most people agree that honesty is a good thing．But does Mother Nature agree？Animals can't talk，but can they lie in other ways？Can they lie with their bodies and behaviors？Animal experts may not call it lying，but they do agree that many animals，from birds to chimpanzees，behave dishonestly to fool other animals．Why？Dishonesty often helps them survive．
Many kinds of birds are very successful at fooling other animals．For example，a bird called the plover sometimes pretends to be hurt in order to protect its young．When a predator（獵食動(dòng)物）gets close to its nest，the plover leads the predator away from the nest．How？It pretends to have a broken wing．The predator follows the"hurt"adult，leaving the baby birds safe in the nest．
Another kind of bird，the scrub jay，buries its food so it always has something to eat．Scrub jays are also thieves．They watch where others bury their food and steal it．But clever scrub jays seem to know when a thief is watching them．So they go back later，unbury the food，and bury it again somewhere else．
Birds called cuckoos have found a way to have babies without doing much work．How？They don't make nests．Instead，they get into other birds'nests secretly．Then they lay their eggs and fly away．When the baby birds come out，their adoptive parents feed them．
Chimpanzees，or chimps，can also be sneaky．After a fight，the losing chimp will give its hand to the other．When the winning chimp puts out its hand，too，the chimps are friendly again．But an animal expert once saw a losing chimp take the winner's hand and start fighting again．
Chimps are sneaky in other ways，too．When chimps find food that they love，such as bananas，it is natural for them to cry out．Then other chimps come running．But some clever chimps learn to cry very softly when they find food．That way，other chimps don't hear them，and they don't need to share their food．
As children，many of us learn the saying"You can't fool Mother Nature．"But maybe you can't trust her，either．

分析 本文是一篇科教類閱讀，屬于說明文，主要通過舉了一些鳥類和大猩猩的例子，說明動(dòng)物有時(shí)會(huì)撒謊，這也是它們生存的需要．
解答 25．D．細(xì)節(jié)理解題：根據(jù)第二段的第二句話：a bird called the plover sometimes pretends to be hurt in order to protect its young．可知啄木鳥保護(hù)孩子不受獵食動(dòng)物侵害是通過假裝受傷，所以選D．
26．C．句意理解題：根據(jù)第五段的最后一個(gè)句子：But an animal expert once saw a losing chimp take the winner's hand and start fighting again．一個(gè)輸了的大猩猩抓住獲勝的大猩猩的手又開始打斗了，可知這句話的意思是大猩猩也可能不誠實(shí)，所以選C．
27．D．細(xì)節(jié)理解題：根據(jù)文章第六段的句子：But some clever chimps learn to cry very softly when they find food．That way，other chimps don't hear them，and they don't need to share their food可知一些大猩猩放低它們的叫聲，這樣讓別的大猩猩得不到食物，所以選D．
