13、ish forest floors. Thats a good thing for the environment: If the carbon remains hidden in the soil，then its not escaping into the atmosphere. There，it could contribute to global warming. These organisms，called mycorrhizal fungi (真菌)，grow on tree roots. They provide trees with nutrients in exchange
14、for their sugars，which contain carbon. Scientists had long believed that most of the carbon sits above ground. But the new study suggests most carbon is trapped in the soil. Carbon is a building block of every living organism，from people and fish to bacteria and trees. Trees are masters at stashing
15、carbon. They breathe in carbon dioxide from the air. They use the carbon to grow branches，leaves and roots. But the element moves around. If a tree falls down and rotsor is cut down and burnedits carbon goes back into the air as carbon dioxide. Too much of the gas in the air can foster global warmin
16、g. In cold northern forests，like those in Sweden，fallen leaves and branches take a long time to rot. That means the carbon in those materials can stay put for a long time. To learn more about what a tree does with its carbon，ecologists at the Swedish University collected soil from 30 forested Swedis
17、h islands. They then measured the amount and age of the carbon in the samples. The scientists found that deeper，fungifilled soils contained more carbon than soils from the surface of the forest floor. When the scientists dated the carbon in the samples，they got a surprise：They found “young” carbon i
18、n deeper soils. The researchers had expected to find young carbon only in soils closer to the surface of the forest floor. The only explanation，they say：The young carbon came from the underground fungi that swallow carboncontaining sugars from tree roots. With the new findings，scientists may better
19、understand soils role in storing carbon. That information could help improve forecasts for global warming. 【解题导语】本文是一篇科普说明文。研究发现，一种真菌能通过吸收树根中蕴含碳的糖，从而将碳储藏在深层土壤中。4How do fungi grow?AThey consume carbon dioxide. BThey digest fallen tree branches. CThey absorb nutrients from the soil. DThey obtain sugar
20、s from tree roots. 解析：选D细节理解题。根据第二段“These organisms，called mycorrhizal fungi. . . which contain carbon. ”可知，这种真菌生长于树的根部，它们为树木提供营养，以换取树木中含有碳的糖。据此可知，这种真菌吸收树根中的糖分，故D项正确。5What does the underlined word “stashing” in Paragraph 3 mean?AStoring. BReducing. CTransforming. DProducing. 解析：选A词义猜测题。根据第三段第四至五句“Tr
21、ees are masters at stashing carbon. They breathe in carbon dioxide from the air”可知，树木从空气中吸进二氧化碳，所以树木是储藏碳的能手；据此可以判断，画线词意为“储存”，故A项正确。6Why were the scientists surprised at the findings?AYoung carbon was found in the surface of the forest floor. BThe findings could not be explained scientifically. CThe
22、findings proved their previous ideas wrong. DIt is hard to find young carbon in the underground fungi. 解析：选C推理判断题。根据第六段中的“They found young carbon in deeper soils. . . the surface of the forest floor. ”可知，研究人员原以为新碳应存在于靠近地表的土壤中，但是研究发现，新碳却存在于深层土壤中，即发现的结果与他们先前的推论不一样，故他们感到惊讶，故C项正确。7Which of the following
23、 can be the best title for the text?AFungi in Cold Northern ForestsBFungi as Carbon KeepersCFungi on the Roots of TreesDFungi in the Deep Soil解析：选B标题归纳题。通读全文可知，本文是一篇科普说明文，主要介绍了一种真菌能通过吸收树木的糖，从而将碳储藏在深层土壤中。据此可知，这种真菌是碳的保存者，故B项最能概括文意，故B项正确。. 语法填空There was a proud teak tree in the forest.
