Forests give us shade,quiet and one of the harder callenges 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 absorb carbon now.Califormia 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.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 insects.The landscape is rendered less easily burnable.Even in the event of a fire,fewer trees are consumed.

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

California plans to treat 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,about half a million acres in all,so it will be vital 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 or burned as biofuel in vehicles that would otherwise run on fossil fuels.New research on transportation biofuels is already under way.

State governments are well accustomed to managing forests,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.Califormia's plan,which is expected to be finalized by the governor next year,should serve as a model.

26.By saying“one of the harder challenges,”the author implies that_________.

A.global climate change may get out of control

B.people may misunderstand global warming

C.extreme weather conditions may arise

D.forests may become a potential threat

27.To maintain forests as valuable“carbon sinks,"we may need to__________.

A.preserve the diversity of species in them

B.accelerate the growth of young trees

C.strike a balance among different plants

D.lower their present carbon-absorbing capacity

26—27参考答案及解析：

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

【解析】根据题干信息词定位到首段。第一句引出文章话题“在人类对抗气候变化中，森林给我们带来了一个更为艰巨的挑战。”第二句指出人类正在威胁到森林吸收二氧化碳的能力。第三句“The climate change we are hastening could one day leave us with forest that emit more carbon than they absorb.”为本段的主题句，指出我们人类所造成的气候变化问题最终会使得森林排放更多的二氧化碳，而不是吸收。即森林可能会威胁气候的恶化和人类的生存。故选择D项“森林可能会变为一个潜在威胁。”

27.【答案】D Lower their present carbon-absorbing capacity

【解析】根据题干要求定位到第二段。该段首句中的前半句there is a way out of this trap对应题干中To maintain forest as valuable“carbon sinks”,后半句提出具体的解决方法it involves striking a subtle balance(这需要达到一个微妙的平衡)，但并没有说这个平衡是不同植被间的平衡，故不能据此选[C]strike a balance among different plants。紧接着第二句提到要达到这一目的可能需要reducing their(forests’)capacity to absorb carbon now(降低他们(森林)现在吸收碳的能力)，由此可知正确答案应为[D]选项。
