Question

Easter(復(fù)活節(jié)) is still a great day for worship, randy in baskets and running around the yard finding eggs, but every year it gets quite a bit worse for bunnies.
And no, not because the kids like to pull their ears. The culprit is climate change, and some researchers found that rising temperatures arc having harmful effects on at least five species of rabbit in the US.
Take the Lower Keys March rabbit, for instance. An endangered species that lives in the Lower Florida Keys, this species of cottontail is a great swimmer — it lives on the islands! — but it is already severely affected by development and now by rising levels. According to the Center for Biological Diversity, an ocean level rise of only 0. 6 meters will send these guys jumping to higher ground and a 0.9-meter rise would wipe out their habitat (棲息地) completely.
The snowshoe hare, on the other hand, has a color issue. Most of these rabbits change their fur color from white in the wintertime to brown in the summer, each designed to give them better cover from predators（捕食者）.  As the number of days with snow decreases all across the country, however, more and more bunnies arc being left in white fur during brown dirt days of both fall and spring, making them an easier mark for predators. Researchers know that the color change is controlled by the number of hours of sunlight, but whether the rabbit will be able to adapt quick enough to survive is a big question. The National Wildlife Federation has reported that hunters have noticed their numbers are already markedly down.
American pikas or rock rabbits, a relative of rabbits and hares, might be the firs' of these species to go extinct due to climate change. About 7-8 inches long, pikas live high in the cool, damp mountains west of the Rocky Mountains. As global temperatures rise, they would naturally migrate (遷徙) to higher ground — but they already occupy the mountaintops. They can't go any higher. The National Wildlife Federation reports that they might not be able to stand the new temperatures as their habitat beats up.
The volcano rabbit has the same problem. These rabbits live on the slopes of volcanoes in Mexico, and recent studies have shown that the lower range of their habitat has already shifted upward about 700 meters, but there are not suitable plants for them to move higher, so they are stuck in the middle. Scientists are concerned about their populations.
Native to the US, pygmy rabbits weigh less than 1 pound and live in the American West. They are believed to be the smallest rabbits in the world. Their habitats have been destroyed by development. Several populations, such as the Columbia Basin pygmy, almost went extinct and were saved by zoo breeding programs. Pygmy rabbits also rely on winter cover by digging tunnels through the snow to escape predators, but lesser snowfall is leaving them exposed.
All of this gives new meaning to dressing up in a giant bunny costume this Easter.

【文章大意】每年復(fù)活節(jié)可愛兔子給大家?guī)�來了多少歡樂，然而隨著全球溫暖趨勢的加劇，這種給我們帶來的愉悅兔子也不可避免地受到了一定的影響。不久的將來，復(fù)活節(jié)上兔子的服飾也會(huì)因此而有所變化。
1.目的意圖題。根據(jù)第一段在全文中的作用可以看出，本段主要目的是導(dǎo)入主題，即：關(guān)于兔子的問題。
2.詞義猜測題。根據(jù)文章第一段最后一句后半句：but every year it gets quite a bit worse for bunnies.和第二段的第一句：And no, not because the kids like to pull their ears.可知答案A，罪過，符合文意。
3.細(xì)節(jié)理解題。根據(jù)第三段的整體理解和倒數(shù)第二句but whether the rabbit will be able to adapt quick enough to survive is a big question.的總結(jié)，可知答案C符合文意。
4.細(xì)節(jié)理解題。根據(jù)文章倒數(shù)第三段的第三句they would naturally migrate (遷徙) to higher ground — but they already occupy the mountaintops. They can't go any higher.和倒數(shù)第二段第二句的后半部分but there are not suitable plants for them to move higher,可知，故答案D符合文意。
5.作者態(tài)度題。根據(jù)文章的整體理解，可知推斷出作者對(duì)兔子這一問題很是關(guān)切(concerned)，故答案B符合文意。Approving贊同的；Enthusiastic熱情的；Doubtful質(zhì)疑的，均不符合語境， 故排除。
【長難句解析】Most of these rabbits change their fur color from white in the wintertime to brown in the summer, each designed to give them better cover from predators（捕食者）。大多數(shù)這種兔子會(huì)把冬天時(shí)的白色皮毛變成夏季的棕色，每一種顏色的變化是為了讓他們更好地避免捕食者的發(fā)現(xiàn)。Designed是非謂語，與其邏輯主語each構(gòu)成被動(dòng)關(guān)系，故用過去分詞作狀語。此外由于each和句子主語most of these rabbits不是同一事物，因此這種非謂語結(jié)構(gòu)在語法上被稱之為獨(dú)立主格結(jié)構(gòu)。
