　　Forests give us shade, quiet and one of the harder challenges in the fight against climate change. Even as we humans count on forests to soak up a good share of the carbon dioxide we produce, we are threatening their ability to do so. The climate change we are hastening could one day leave us with forests that emit more carbon than they absorb.

　　Thankfully, there is a way out of this trap—but it involves striking a subtle balance. Helping forests flourish as valuable "carbon sinks" long into the future may require reducing their capacity to sequester carbon now. California is leading the way, as it does on so many climate efforts, in figuring out the details.

　　The state's proposed Forest Carbon Plan aims to double efforts to thin out young trees and clear brush in parts of the forest, including by controlled burning. This temporarily lowers carbon-carrying capacity. But the remaining trees draw a greater share of the available moisture, so they grow and thrive, restoring the forest's capacity to pull carbon from the air. Healthy trees are also better able to fend off bark beetles. The landscape is rendered less combustible. Even in the event of a fire, fewer trees are consumed.

　　The need for such planning is increasingly urgent. Already, since 2010, drought and beetles have killed more than 100 million trees in California, most of them in 2016 alone, and wildfires have scorched hundreds of thousands of acres.

　　California's plan envisions treating 35,000 acres of forest a year by 2020, and 60,000 by 2030 —financed from the proceeds of the state's emissions-permit auctions. That's only a small share of the total acreage that could benefit, an estimated half a million acres in all, so it will be important to prioritize areas at greatest risk of fire or drought.

　　The strategy also aims to ensure that carbon in woody material removed from the forests is locked away in the form of solid lumber, burned as biofuel in vehicles that would otherwise run on fossil fuels, or used in compost or animal feed. New research on transportation biofuels is under way, and the state plans to encourage lumber production close to forest lands. In future the state proposes to take an inventory of its forests' carbon-storing capacity every five years.

　　State governments are well accustomed to managing forests, including those owned by the U.S. Forest Service, but traditionally they've focused on wildlife, watersheds and opportunities for recreation. Only recently have they come to see the vital part forests will have to play in storing carbon. California's plan, which is expected to be finalized by the governor early next year, should serve as a model.

　　B. forests may become a potential threat

　　C. people may misunderstand global warming

　　D. extreme weather conditions may arise

　　27. To maintain forests as valuable "carbon sinks", we may need to _

　　A.preserve diversity of species

　　B. lower their present carbon-absorbing capacity

　　C. accelerate the growth of young trees

　　D. strike a balance among different plants

　　28.California's Forest Carbon Plan endeavors to ___

　　A. restore its forests quickly after wildfires.

　　B. cultivate more drought resistant trees.

　　C. find more effective ways to kill insects

　　D. reduce the density of some of its forests

　　29. What is essential to California's plan according to para. 5?

　　A. To obtain enough financial support

　　B. To carry it out before 2020

　　C. To handle the areas in the serious danger first

　　D. To perfect the emission-permit auctions

　　30.the author's attitude toward California's plan can be best described as ____

　　A. supportive

　　B. ambiguous

　　C. tolerant

　　D. cautious

　　26. 答案【B】 forests may become a potential threat

　　解析：本題目為推斷題，考察推理判斷能力。根據(jù)題干關(guān)鍵詞One of the harder challenges定位到第一段第一，二句。森林為我們提供了陰涼、寧靜的環(huán)境，是應對氣候變化斗爭中更艱巨的挑戰(zhàn)之一。即使我們?nèi)祟愔竿治瘴覀兩a(chǎn)的大部分二氧化碳，我們也威脅著森林吸收二氧化碳的能力。正確答案B的 forests may become a potential threat森林可能成為潛在的威脅，是原文we are threatening their ability to do so. 我們也威脅著森林吸收二氧化碳的能力的同義替換，選項中的threat替換原文的threatening。干擾項A 的global climate change may get out of contro全球氣候變化可能失控原文并未提及，屬于無中生有;選項C的people may misunderstand global warming人們可能誤解全球變暖 原文并未提及，屬于無中生有;選項D的extreme weather conditions may arise可能出現(xiàn)極端天氣情況并未提及，是過度推理。

　　27. 答案【B】 lower their present carbon-absorbing capacity

　　解析：本題目為細節(jié)題，考察具體細節(jié)。根據(jù)題干關(guān)鍵詞To maintain forests as valuable "carbon sinks",定位到第二段第二句。Helping forests flourish as valuable "carbon sinks" long into the future may require reducing their capacity to sequester carbon now.隨著"carbon sinks"長期存在，幫助森林繁榮可能需要減少它們現(xiàn)在吸收碳的能力。題干中的need定位原文中的require，正確答案lower their present carbon-absorbing capacity降低他們目前的碳吸收能力，lower降低替換原文的 reducing 減少，capacity文中原詞，carbon-absorbing 替換原文 sequester carbon。干擾項A 的preserve diversity of species保護物種多樣性，原文并未提及，屬于無中生有;選項C的accelerate the growth of young trees促進幼樹生長，選項Dstrike a balance among different plants在不同植物之間取得平衡，故正確答案為B

　　28答案【D】 reduce the density of some of its forests

　　解析：本題目為細節(jié)題，考察具體細節(jié)。根據(jù)題干關(guān)鍵詞California's Forest Carbon Plan第三段第一句，題干中endeavors to 努力做替換原文的 double efforts to，原文thin out young trees and clear brush in parts of the forest, including by controlled burning通過控制燃燒，使部分森林中的幼樹變薄，清除灌木。選項D reduce the density of some of its forests減少一些森林的密度，正是原文幼樹變薄，清除灌木的同意轉(zhuǎn)換。干擾項A restore its forests quickly after wildfires.野火過后迅速恢復森林。無關(guān)信息。選項B cultivate more drought resistant trees. 培育更多的抗旱樹木。正反混淆。選項C，find more effective ways to kill insects找到更有效的殺蟲方法，屬于無關(guān)信息。

　　29答案【C】To handle the areas in the serious danger first 先處理嚴重危險地區(qū)

　　解析：本題目為細節(jié)題，考察具體細節(jié)。根據(jù)題干關(guān)鍵詞California's plan according to para. 5定位到第五段第二句，題干中的essential替換到 so it will be important to prioritize areas at greatest risk of fire or drought.中的important，因此，將火災或干旱風險最大的地區(qū)列為優(yōu)先重點將是重要的。正確選項C To handle the areas in the serious danger first 先處理嚴重危險地區(qū)，其中原文prioritize替換選項handle ...first, areas in the serious danger替換原文的areas at greatest risk。干擾選項ATo obtain enough financial support，獲得足夠的財政支持，原文并未提及，屬于常識性干擾。B選項To carry it out before 2020在2020年前實施 選項DTo perfect the emission-permit auctions完善排污權(quán)拍賣制度，均屬于無關(guān)信息。

　　30 答案【A】supportive

　　解析：本題目為態(tài)度題，考察作者態(tài)度。根據(jù)題干關(guān)鍵詞 California's plan定位到最后一段最后一句，California's plan, which is expected to be finalized by the governor early next year, should serve as a model.預計明年年初州長將敲定該法案，這應該可以作為一個范例，起到榜樣作用，因此作者采取正面態(tài)度，A supportive支持的，B ambiguous 含糊的C. tolerant忍受的D. cautious謹慎的，只有A表達正面支持的態(tài)度
