Over their lifetimes, then, urban trees will likely absorb less CO2 from the air than forest trees. As we all know, the earth would be freezing or burning hot without CO2. However, CO2 is a greenhouse gas, meaning it traps energy from the sun as/heat. That makes temperatures near the ground rise. Human activities, especially the widespread burningof fossil(化石)fuels, have been sending extra greenhouse gases into the air. This has led to a rise in average temperatures across the globe. Studies had shown forests readily absorb CO2, but there hadn39。t been much data on whether city trees grow, die and absorb CO2 at the same rate as forest trees do. So some researchers decided to find out. To figure out how quickly trees were growing, researchers tracked their diameters (the width of their trunks) between 2005 and 2014. A tree39。s diameter increases as it grows, just as a person39。s waist size increases as they gain weight. About half the weight of a tree is carbon, research has shown. Most of the rest is water. Over the nine years39。 tracking, the researchers found city trees absorbed four times as much carbon from the air as forest trees. However, they were twice as likely to die. So over the lifetime of each type of tree, forest trees actually absorbed more CO2. City trees grew faster because they had less petition for light from their neighbors. In a forest，trees tend to grow close together，shading their neighbors. Street trees also benefit from higher levels of nitrogen (氮)in rainwater. Nitrogen helps plants grow. Waste gases from gasburning cars also contain nitrogen, thus enriching city air with nitrogen. Later, rainwater may wash much of it to the ground. Some street trees may also have better access to water than trees in the country because the underground water pipes can leak.（1）What can he known about CO2 from paragraph 2?

Nitrogen helps plants grow. Waste gases from gasburning cars also contain nitrogen, thus enriching city air with nitrogen. Later, rainwater may wash much of it to the ground.”可知，與生長(zhǎng)在森林中的樹(shù)木相比，城市里的樹(shù)木長(zhǎng)得更快是因?yàn)樗鼈儫o(wú)需與鄰近的樹(shù)木爭(zhēng)奪光照，也能得到更多的氮量，還更容易得到水。光、氮和水都可以促進(jìn)樹(shù)木的生長(zhǎng)。由此可以推斷，城市里的樹(shù)木比森林中的樹(shù)木更可能獲得生長(zhǎng)促進(jìn)劑。故選A。 （4）考查推理判斷。首句就提到了一項(xiàng)新的研究結(jié)果：城市里的樹(shù)木比森林中的樹(shù)木長(zhǎng)得更快，但死得更早；文章第三段說(shuō)到“以前有研究表明森林會(huì)吸收二氧化碳，但是城市里的樹(shù)木的生長(zhǎng)、死亡和吸收二氧化碳的速度是否跟森林中的樹(shù)木一樣，這方面的數(shù)據(jù)不多。因此一些研究人員決定弄清楚”；文章第四段再次介紹了他們的研究發(fā)現(xiàn)：城市里的樹(shù)木比森林中的樹(shù)木長(zhǎng)得更快，但死得更早；文章最后一段介紹了城市里的樹(shù)木比森林中的樹(shù)木生長(zhǎng)得更快的幾個(gè)原因。由此可以推斷，文章接下來(lái)很可能就要介紹城市里的樹(shù)木死得更早的原因。故選B。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解和推理判斷兩個(gè)題型的考查，是一篇科研類(lèi)閱讀，考生需要準(zhǔn)確掌握細(xì)節(jié)信息，并根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。8．閱讀理解 On December 26, 2004, hundreds of tourists relaxed on Sri Lanka39。s Yala National Park39。s beaches. But at midmorning the park39。s elephants began crying wildly and running away from the ocean and up a nearby hill. The puzzled keepers could tell the animals were worried about something but what? What the keepers did not know was that a 30foot wall of water was headed straight toward them. This tsunami(海嘯) had been caused by an earthquake more than 1, 000 miles away in the Indian Ocean. When the huge wave hit the coast, it caused severe damage. Many people died. The elephants, however, were not swept away by the water. They stood safely on the hill. Scientists have long suspected that animals sense natural disasters before humans do. People have told stories of dogs refusing to go outside and sharks swimming to deeper waters before a hurricane. After the 2004 tsunami, people said they saw tigers, monkeys, and water buffalo escaping to higher ground before the waters rushed in. Even in the hardesthit areas of southern Asia, there were few animal deaths. It39。s unlikely that an animal39。s socalled sixth sense es from some magical power to see into the future. Experts believe that animals may be more sensitive th
