2020-2021高考英语阅读理解训练经典题目(含答案)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 than 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 C02.【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 tra cked 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。

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，考生需要准确掌握细节信息，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In modern society there is a great deal of argument about competition. Some value it highly, believing that it is responsible for social progress and prosperity(繁荣). Others say that competition is bad; that it sets one person against another; that it leads to unfriendly relationship between people.I have taught many children who held the belief that their self-worth relied on how well they performed at tennis and other skills. For them, playing well and winning are often life-and-death affairs. In their single-minded pursuit of success, the development of many other human qualities is sadly forgotten.However, while some seem to be lost in the desire to succeed, others take an opposite attitude.In a culture which values only the winner and pays no attention to the ordinary players, they strongly blame competition. Among the most vocal are youngsters who have suffered under competitive pressures from their parents or society. Teaching these young people, I often observe in them a desire to fail. They seem to seek failure by not trying to win or achieve success. By not trying, they always have an excuse: "I may have lost, but it doesn't matter because I really didn't try."What is not usually admitted by themselves is the belief that if they had really tried and lost, that would mean a lot. Such a loss would be a measure of their worth. Clearly, this belief is the same as that of the true competitors who try to prove themselves. Both are based on the mistaken belief that one's self-respect relies on how well one performs in comparison with others. Both are afraid of not being valued. Only as this basic and often troublesome fear begins to dissolve(缓解)can we discover a new meaning in competition.（1）Why are some people in favor of competition?A. Because they think competition pushes society forward.B. Because they think competition improves social abilities.C. Because they think competition builds up a sense of pride.D. Because they think competition develops people's relationship.（2）What does the underlined phrase "the most vocal" in Paragraph 3 refer to?A. People who try their best to win.B. People who highly value competition.C. People who are strongly against competition.D. People who mostly rely on others for success.（3）Which viewpoint does the author agree to?A. Self-worth relies on winning.B. Winning should be a life-and-death matter.C. Competition leads to unfriendly relationship.D. Fear of failure should be removed in competition.（4）What does the passage mainly talk about?A. Competition helps to set up self-respect.B. People hold different opinions about competition.C. Failures are necessary experience in competition.D. Competition is harmful to personal quality development.【答案】（1）A（2）C（3）D（4）B【解析】【分析】本文是一篇议论文，论述了人们对于竞争所持的不同观点。
