11．Cats like climbing trees and there are logical reasons behind this behavior．Interestingly，due to some of their physical features，cats will meet trouble getting down from the trees after climbing up，which may seem unusual．
There are several reasons why cats climb trees，mostly to do with defensive purposes．Cats，as predators（捕食者），like to understand their environment well．As they are small animals，their scope of vision is considerably smaller．Cats often climb trees to get a better view of their surroundings to help them see any potential dangers．
While cats are predators，they are also easy to get attacked from larger animals，such as dogs or even other cats．A tree often provides a safe hiding place．In the wild，cars climb up trees to give them a resting or napping place that is out of predators'range．It also helps disguise their presence．
Some cats may climb trees for fun，on occasion，or possibly to work on improving their climbing abilities．Small cats frequently test out their claw skills by trying to climb up anything and everything，from bookcases to trees to a person's leg．Climbing practice is good for cats； it can improve their strength and flexibility and teach them an important defensive skill．
If a cat has gotten up a tree and cannot get down，the owner may wonder why its remarkable climbing abilities only work in one direction．A cat's claws curve inward，allowing it to grip onto surfaces while going up head first．Unfortunately，this useful climbing curve does nothing to help the animal get back down again．
Eventually，most trapped cats will either jump out of the tree or realize that they can get down by going tail first．Either way，a cat up a tree is usually nothing to worry about； they are intelligent animals and will figure out how to get down sooner or later．

解答 28．B．細(xì)節(jié)理解題．根據(jù)第四段Some cats may climb trees for fun，on occasion，or possibly to work on improving their climbing abilities可知小貓咪喜歡爬一個(gè)人的腿去鍛煉他們的爪子技能；故選B．
29．D．細(xì)節(jié)理解題．根據(jù)第五段 cat's claws curve inward，allowing it to grip onto surfaces while going up head first．Unfortunately，this useful climbing curve does nothing to help the animal get back down again可知貓從樹上爬下來有困難因?yàn)樗呐逝滥芰Σ贿m合趴下來；故選D．
30．A．推理判斷題．根據(jù)最后一段Either way，a cat up a tree is usually nothing to worry about； they are intelligent animals and will figure out how to get down sooner or later可知當(dāng)你看到一只貓被困在樹上時(shí)，你不需要理會(huì)；故選A．
31．A．主旨大意題．根據(jù)第一段Cats like climbing trees and there are logical reasons behind this behavior可知本文主要討論為什么貓喜歡爬樹的邏輯原因；故選A．
點(diǎn)評 考察學(xué)生的細(xì)節(jié)理解和推理判斷能力，做細(xì)節(jié)理解題時(shí)一定要找到文章中的原句，和題干進(jìn)行比較，再做出正確的選擇．在做推理判斷題不要以個(gè)人的主觀想象代替文章的事實(shí)，要根據(jù)文章事實(shí)進(jìn)行合乎邏輯的推理判斷．
