15、 than 46,000 square miles of California forests, the new study finds. No area was spared or unaffected, from the foggy northern coast to the Sierra Nevada Mountains to the San Gabriels above Los Angeles. In the Sierra high country, the number of big trees has fallen by more than 55 percent; in parts

16、 of southern California the decline was nearly 75 percent.Many factors contributed to the decline, said Patrick McIntyre, an ecologist who was the lead author of the study. Woodcutters targeted big trees. Housing development pushed into the woods. Aggressive wildfire control has left California fore

17、sts crowded with small trees that compete with big trees for resources (资源)But in comparing a study of California forests done in the 1920s and 1930s with another one between 2001 and 2010, McIntyre and his colleagues documented a widespread death of big trees that was evident even in wildlands prot

18、ected from woodcutting or development.The loss of big trees was greatest in areas where trees had suffered the greatest water shortage. The researchers figured out water stress with a computer model that calculated how much water trees were getting in comparison with how much they needed, taking int

19、o account such things as rainfall, air temperature, dampness of soil, and the timing of snowmelt (融雪)Since the 1930s, McIntyre said, the biggest factors driving up water stress in the state have been rising temperatures, which cause trees to lose more water to the air, and earlier snowmelt, which re

20、duces the water supply available to trees during the dry season.篇章导读：本文是一篇调查报告。调查表明，加利福尼亚州的大树变少了，而气候变化是其中的一个主要因素。1What is the second paragraph mainly about?AThe seriousness of bigtree loss in California.BThe increasing variety of California big trees.CThe distribution of big trees in California fore

22、造成加利福尼亚州的大树减少的三个因素：woodcutters，housing development与aggressive wildfire control。前两个因素直接与大树的减少有关，如果能控制住，大树就不会减少；而第三个因素控制野火的措施使得加利福尼亚州的森林里满是跟大树争夺资源的小树，初衷是为了控制野火，这是好的，实则对大树不利，故D项正确。3What is a major cause of the water shortage according to McIntyre?AInadequate snowmelt.BA longer dry season.CA warmer clim

23、ate.DDampness of the air.答案：C细节理解题。根据文章最后一段中的“. the biggest factors driving up water stress in the state have been rising temperatures .”可知，水资源不足的主要原因就是气温升高，即更加温暖的气候，故C项正确。4What can be a suitable title for the text?ACalifornias Forests：Where Have All the Big Trees Gone?BCutting of Big Trees to Be Pr

25、ter 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, CO2 is a greenhouse gas, meaning it traps energy fro

26、m 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 C

27、O2，but there hadnt 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 trees d

28、iameter increases as it grows, just as a persons 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 fores

29、t 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. Stre

30、et 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

31、 than trees in the country because the underground water pipes can leak.篇章导读：本文是一篇说明文。文章阐述了一项新的研究发现：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。5What can be known about CO2 from Paragraph 2?AIt is one of the side effects of greenhouses.BIt greatly accelerates the process of global warming.CIt results from the wide

32、spread burning of fossil fuels.DIt prevents the earth from becoming unsuitable to live on.答案：D推理判断题。根据文章第二段中的“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。由此可以推断，二氧化碳可以防止地球变得不适合居住。6Why did researchers track the diameters of trees?ATo know about their growth rates.BTo

33、find out how much they weigh.CTo check whether they were healthy.DTo assess the carbon amounts in them.答案：A细节理解题。根据文章第四段中的“To figure out 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。7What advantage do city trees have over forest trees?AThey are more l

34、ikely to access growth promoters.BThey can enjoy more water coming from the air.CThey can enjoy more shade from neighbors.DThey are better at competing for light.答案：A推理判断题。根据文章最后一段内容可知，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。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。8What will probably be ta

35、lked about if the passage is continued?AHow urban trees can live longer.BWhy city living makes trees die young.CHow trees respond to dry soil conditions.DWhy fastergrowing trees absorb more CO2.答案：B推理判断题。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

40、为可数名词，此处表示“一个学生”，应在student前加a。2isare考查主谓一致。句子的主语“capital volunteers”是复数名词。3tofor考查介词。apply for意为“申请”，而apply to意为“应用于”。4删除to考查情态动词。can为情态动词，后接动词原形。5thatwhich考查定语从句的引导词。此处是非限制性定语从句，先行词为整个主句所述内容，关系词应用which。6knowledgesknowledge考查名词。因为knowledge是不可数名词，没有复数形式。7spreadingspread考查动词的用法。be willing to do sth. “愿意做某事”，为固定短语，故改为动词原形spread。8possiblypossible考查形容词。此处作动词make的宾语补足语。用形容词作宾语补足语，说明宾语的属性。9themit考查代词。“Id appreciate it if .”是固定句型，it指代if引导的从句的内容。10yourmy考查代词。因为主语是I，物主代词应当与主语呼应。 - 11 - 版权所有高考资源网
