一、高中英语阅读理解1．阅读理解City trees grow faster and die younger than trees in rural forestry, a new study finds. Over their lifetimes, then, urban trees will likely absorb less CO2 from the air thah forest trees.As we all know, the earth would be freezing or burning hot without CO2. However, CO2is a greenhouse gas, meaning it traps energy from the sun as/heat. That makes temperatures near the ground rise. Human activities, especially the widespread burning-of 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 hadn't been much data on whether city trees grow, die and absorb CO2at 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 tree's diameter increases as it grows, just as a person'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 years' 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 competition 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 gas-burning 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?A. It is one of the side effects of greenhouses.B. It greatly accelerates the process of global warming.C. It results from the widespread burning of fossil fuels.D. It prevents the earth from becoming unsuitable to live on.（2）Why did researchers track the diameters of trees?A. To know about their growth rates.B. To find out how much they weigh.C. To check whether they were healthy.D. To assess the carbon amounts in them.（3）What advantage do city trees have over forest trees?A. They are more likely to access growth promoters.B. They can enjoy more water coming from the air.C. They can enjoy more shade from neighbors.D. They are better at competing for light.（4）What will probably be talked about if the passage is continued?A. How urban trees can live longer.B. Why city living makes trees die young.C. How trees respond to dry soil conditions.D. Why faster-growing trees absorb more CO2.【答案】（1）D（2）A（3）A（4）B【解析】【分析】本文是一篇说明文，一项新的研究发现：与长在森林中的树木相比，城市里的树木长得更快，但死得更早。
（1）考查推理判断。
根据第二段中的“the earth would be freezing or burning hot without CO2.”可知，如果没有二氧化碳，地球将会极冷或极热。
可以推断，二氧化碳可以防止地球变得不适合居住。
故选D。
（2）考查细节理解。
根据第四段中的“To figure on how quickly trees were growing, researchers tracked their diameters.”可知，研究人员监测树木的直径是为了了解树木的生长速度。
故选A。
（3）考查细节理解。
根据最后一段中的“Street trees also benefit from higher levels of nitrogen (氮）in rainwater. Nitrogen helps plants grow. Waste gases from gas-burning cars also contain nitrogen, thus enriching city air with nitrogen. Later, rainwater may wash much of it to the ground.”可知，与生长在森林中的树木相比，城市里的树木长得更快是因为它们无需与邻近的树木争夺光照，也能得到更多的氮量，还更容易得到水。
光、氮和水都可以促进树木的生长。
由此可以推断，城市里的树木比森林中的树木更可能获得生长促进剂。
故选A。
（4）考查推理判断。
文章首句就提到了一项新的研究结果：城市里的树木比森林中的树木长得更快，但死得更早；文章第三段说到“以前有研究表明森林会吸收二氧化碳，但是城市里的树木的生长、死亡和吸收二氧化碳的速度是否跟森林中的树木一样，这方面的数据不多。
因此一些研究人员决定弄清楚”；文章第四段再次介绍了他们的研究发现：城市里的树木比森林中的树木长得更快，但死得更早；文章最后一段介绍了城市里的树木比森林中的树木生长得更快的几个原因。
由此可以推断，文章接下来很可能就要介绍城市里的树木死得更早的原因。
故选B。
【点评】本题考点涉及细节理解和推理判断两个题型的考查，是一篇科研类阅读，考生需要准确捕捉细节信息，并根据上下文进行逻辑推理，从而选出正确答案。
2．阅读理解At 23 I applied for full-time positions with no intention of working five days a week. As a housewife, I had two pre-school children then but wanted to work three days a week.This was a huge deal for me. I needed to work, but also wanted to spend time with my children while they were young. I didn't want to miss out on school drop-offs and pick-ups. But I also didn't want to miss out on the opportunity of promotion.Before the interviews, I prepared a plan of how I was going to make this work for me and the employer. I saw it as a two-way agreement — the business adapting to me and me adapting to the business.Finally I became a member of EY at 33. EY was the only firm that seemed receptive to my plan; in fact, we spent time during that first interview talking about how we could make it worktogether. Most importantly, the person interviewing me worked flexibly too — four days a week.I appreciated that I'm one of the lucky ones. Even 10 years on, flexible hiring and working remains the exception rather than the rule for most.What will help shift views and behavior, in addition to organizations updating their hiring policies, is talking more openly about how most of us organize our day around our responsibilities. We all have a life outside of work and we shouldn't be embarrassed to talk about it, even during a job interview.It's a change in the way of thinking, not just for employers but employees too. In the early days I was confident about my ability but I probably did have a preconception (先入之见) that working part-time would limit my career progression. What I quickly realized was that if I took responsibility for my development, I could make sure that I got the same opportunities as if I was working full-time. So I offered solutions to how we could make it work, and it made me stand out.（1）Why did the author want a flexible job?A. To balance her work and life.B. To have more time to relax.C. To avoid too much stress in life.D. To stand out as a special woman.（2）What perhaps made the author become a member of EY?A. The time spent discussing her plan.B. Her relationship with the interviewer.C. Her great confidence in the interview.D. The interviewer's understanding her.（3）What does the author advise to apply for a flexible job?A. Trying to seize every opportunity one can get.B. Persuading the company to change its hiring policies.C. Being honest about one's personal life outside of work.D. Convincing the employer of one's responsibility for the job.（4）What can we infer about her job from the passage?A.It weakened her ability.B.It made her highly noticeable.C.It limited her career promotion.D.It caused her to earn less money.【答案】（1）A（2）D（3）D（4）B【解析】【分析】本文是一篇记叙文，作者面试兼职工作时改变传统思路，脱颖而出获得机会，并以此而发表了自己的看法观点。
