All that time helps trees grow faster. For the past 100 years, trees have been experiencing fast growt

6、h in mild areas from Maryland to Finland, to Central Europe, where the growth rate of some trees has even sped up by nearly 77% since 1870. Supposing wood were just as strong today, those gains would mean more wood for building, burning, and storing carbon captured from the atmosphere. But is wood r

7、eally as dense (茂密的) as it used to be? Hans Pretzsch, a forest scientist in Germany, and his colleagues wanted to find an answer. They carried out a study of the forests of Central Europe. They started with small pieces of experimental land in southern Germany, some of which have been continuously m

8、onitored since 1870. Pretzsch and his team took core samples (样品) from the trees which included Norway spruce, sessile oak, European beech, and Scots pine and analyzed the tree rings. They found that in all four species, wood density had decreased by 8% to 12%. We expected a trend of the wood densit

9、y like this, but not such a strong and significant decrease, Pretzsch says. Increasing temperatures, and the faster growth they spur, probably account for some of the drop. Another factor, Pretzsch says, is more nitrogen in the soil from agricultural fertilizer and vehicle exhaust. Previous studies

10、have linked increased fertilizer use to decreased wood density. Above all, the study suggests that the higher temperatures combined with pollution from car exhaust and farms are making wood weaker, resulting in trees that break more easily and wood that is less durable. I am getting worried, says Ri

11、chard Houghton, an ecologist at the Woods Hole Research Center in Massachusetts, who was not part of the new study. As the density of the samples dropped, so did their carbon content. That means forests may suffer more damage from storms and may be less efficient at absorbing carbon dioxide than sci

26、构可知，空处在句中作定语，修饰animals，因live与animals 之间为逻辑上的主谓关系，故应用动词-ing形式。 考查介词。provide sth. for sb.为固定用法，意为为某人提供某物。 考查时态、语态和主谓一致。该句为含有定语从句的复合句，关系词that在定语从句中作 主语，先行词为Anything，因此谓语动词用单数形式；此处陈述的是客观情况，要用一般现 在时；that指代先行词Anything，与动词involve之间为被动关系，故应用被动语态。 考查副词。根据空前的can affect the balance of it以及本句中的can also harm or destroy the system可知，这里表示递进，故填Besides。 考查词形转换。根据 and 前面的部分可知，此处应用 pollute 的名词形式 pollution。
