【正文】 pondent39。s view was greenery. Previous scholarship(學(xué)術(shù)研究) has dealt mostly with exercise in nature: A 2015 study out of the University of Michigan found 90 minute group nature walks were effective at batting depression and relieving other mood disorders. But for people who struggle with accessibility or don39。t have time for a 90minute walk, this new study suggests just looking out a window at a tree can help fight off a bad habit. It has been known for some time that being outdoors in nature is linked to a person39。s wellbeing, lead author Leanne Martin said in a statement. But for there to be a similar association with desires from simply being able to see green space adds a new dimension to the previous research. A 2018 study from Denmark39。s Aarhus University for example, found that. Having access to green space throughout childhood decreased a person39。s risk of developing mental health problems as an adult.（1）What does the second paragraph mainly talk about? results of the new study. purpose of the new study. significance of the new study. content of the new study.（2）What does the underlined word batting in paragraph 4 probably mean? ...（3）According to the passage, the new study _____. referred to exercise in nature enriched the previous research to some degree carried out by the University of Michigan exposure to greenery helped cure mental problems（4）n which section of a newspaper may this passage appear?

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)在森林中的樹木相比，城市里的樹木長(zhǎng)得更快是因?yàn)樗鼈儫o(wú)需與鄰近的樹木爭(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)樹木的生長(zhǎng)。由此可以推斷，城市里的樹木比森林中的樹木更可能獲得生長(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：城市里的樹木比森林中的樹木長(zhǎng)得更快，但死得更早；文章第三段說到“以前有研究表明森林會(huì)吸收二氧化碳，但是城市里的樹木的生長(zhǎng)、死亡和吸收二氧化碳的速度是否跟森林中
