12.In their book Time to Eat the Dog:The Real Guide to Sustainable Living,Robert and Brenda Vale say keeping a medium?sized dog has the same ecological impact as driving 10,000km a year in a 4.6liter Land Cruiser.
"We're not actually saying it is time to eat the dog.We're just saying that we need to think about and know the ecological impact of some of the things we do and that we take for granted."
Constructing and driving the jeep for a year requires 0.41hectares of land,while growing and manufacturing a dog's food takes about 0.84hectares-or 1.1hectares in the case of a large dog such as a German shepherd.
Convincing flesh?eating cats and dogs to go vegetarian for the sake of the planet is a non?starter,the Vales say.Instead they recommend keeping"greener",smaller,and more sustainable pets,such as goldfish,chickens or rabbits.
The book's playful title,and serious suggestion that pet animals may be usefully"recycled",by being eaten by their owners or turned into pet food when they die,may not appeal to animal fans.
Annoying as the idea may be,the question is valid given the planet's growing population and limited resources,Robert Vale said.
"Issues about sustainability are increasingly becoming things that are going to require us to make choices which are as difficult as eating your dog.It's not just about changing your light bulbs or taking a cloth bag to the supermarket,"he said.
"It's about much more challenging and difficult issues,"he added."Once you see where cats and dogs fit in your overall balance of things,you might decide to have the cat but not also to have the two cars and the three bathrooms and be a meat eater yourself."

56.The authors gave their book the playful title toD.
A.make it amusing                      B.create a vivid image
C.show writing skills                 D.a(chǎn)rouse people's concern

A.Going vegetarian.
B.Raising cats and dogs.

59.Who may not like the idea of"recycling"pet animals?C
A.Manufacturers.     B.Drivers.

60.What do the authors think of living a sustainable life?A

分析 本文屬于說明文閱讀,作者通過這篇文章主要向我們描述了是時(shí)候吃狗肉了這本書,用了好玩的標(biāo)題但其主旨是提倡人們發(fā)展可持續(xù)的生活,提出了圈養(yǎng)可持續(xù)的寵物,使用環(huán)保袋等方式,保持綠色生活.

解答 56.D.推理判斷題.根據(jù)文章第四段"The book's playful title,and serious suggestion that pet animals may be usefully"recycled","這本書是好玩的標(biāo)題,和嚴(yán)肅的建議;可知本書用了好玩的標(biāo)題是為了吸引讀者的關(guān)注;故選D.
57.B.推理判斷題.根據(jù)文章第三段"Constructing and driving the jeep for a year requires 0.41 hectares of land,while growing and manufacturing a dog's food takes about 0.84hectares-or 1.1hectares in the case of a large dog such as a German shepherd"修建和駕駛一輛吉普車需要0.41公頃土地而喂養(yǎng)一條狗的食物就需要0.84公頃,大型犬如德國(guó)牧羊犬需要1.1公頃;由此可見第三段主要講了忽視生態(tài)的影響;故選B.
58.D.詞義推斷題.根據(jù)文章第三段"Instead they recommend keeping"greener",smaller,and more sustainable pets,such as goldfish,chickens or rabbits"他們建議保持"綠色"生活,圈養(yǎng)更小的和更可持續(xù)的寵物,如金魚、雞、兔;可知詞義為保持綠色生活;故選D.
59.C.細(xì)節(jié)理解題.根據(jù)文章第四段"by being eaten by their owners or turned into pet food when they die,may not appeal to animal fans"主人吃掉或者變成寵物食品當(dāng)他們死的時(shí)候,這可能無法吸引動(dòng)物愛好者;故選C.
60.A.推理判斷題.根據(jù)文章最后一段"It's about much more challenging and difficult issues,"he added"這是更大的挑戰(zhàn)和困難的問題,"他說;可知作者認(rèn)為過一個(gè)可持續(xù)的生活是具有挑戰(zhàn)性的;故選A.

點(diǎn)評(píng) 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.
