The amount of carbon stored by UK forests underestimated 研究顯示：英國(guó)森林碳儲(chǔ)量被低估
一項(xiàng)新研究顯示，英國(guó)森林鎖住的導(dǎo)致全球變暖的碳是此前認(rèn)為的兩倍。這項(xiàng)使用激光和三維掃描的研究表明，古樹(shù)在應(yīng)對(duì)氣候變化中起到的作用尤為關(guān)鍵。
Professor Kim Calders from Ghent University is laser-scanning what's said to be the UK's most scientifically studied forest: Wytham Wood in Oxfordshire. For their research, he and his colleagues scanned nearly a thousand trees, producing detailed three-dimensional maps from which they could work out the weight of each one.
根特大學(xué)的金·考爾德斯教授正在用激光掃描據(jù)說(shuō)是英國(guó)被研究最多的森林：牛津郡的威薩姆森林。在他們的研究中，考爾德斯教授及其同事掃描了近一千棵樹(shù)，繪制了詳細(xì)的三維地圖，從中可計(jì)算出每棵樹(shù)的重量。
This revealed that an average patch of UK woodland is heavier than was estimated and therefore contains much more carbon – almost twice as much as previously thought. The scientists say their findings show the value of established, mature woodland for fighting climate change has been underestimated.
計(jì)算得出，英國(guó)一塊普通林地的重量比估計(jì)的要重，因此碳含量更高，幾乎是之前估計(jì)的兩倍?？茖W(xué)家們表示，他們的發(fā)現(xiàn)表明，生長(zhǎng)已久的成熟林地在對(duì)抗氣候變化方面的價(jià)值被低估了。

答案
1. According to the report, what is significant about Wytham Wood in Oxfordshire, UK?
Wytham Wood is said to be the UK's most scientifically studied forest.
2. How did the researchers work out the weight of each tree?
Researchers scanned nearly a thousand trees, producing detailed three-dimensional maps from which they could work out the weight of each one.
3. What were researchers able to work out from the weight of the woodland?
By calculating the weight of a patch of woodland, they could work out how much carbon it contains.
4. True or false? This research concluded older woodland can help fight climate change more than was first thought.
True. The scientists say their findings show the value of established, mature woodland for fighting climate change has been underestimated.
