福州一中2020届高三教学反馈检测试卷语文科(试题卷)满分150分考试用时150分钟2020.3一、现代文阅读(36分)(―)论述类文本阅读(本题共3小题,9分)阅读下面的文字,完成下面小题。
艺术活动,不管是创作也好,欣赏也好,总离不开一个“我”。
在艺术活动中要是抽去了“我”,抽去了个人的思想感情,就不成其为一种艺术活动,也就不会有感染人、影响人的艺术效果了。
当然,离不开“我”,并不是只有“我”。
“我”,是时时处在“非我”的包围影响中的“我”。
所谓“非我”,就是“我”以外的一切人以及包围着“我”的客观现实。
文学艺术总应该是生活现实的反映,而不能只是作者的自我表现。
但文学艺术的反映,不同于其他形式的反映,它必须是具体的、形象的反映。
不使自己化为张三李四,不感受体验着张三李四的思想感情,就写不出张三李四来;不使自己融入客观现实之中,不呼吸着客观现实的气息,不感受着客观现实的脉搏,就写不出生动的客观现实来。
所以,创作者首先必须要有一个使“我”化为“非我”的过程。
另一方面,文艺作品之所以要写出张三李四等人物来,要反映客观现实,又不是无所为的,不是为写张三李四而写张三李四,为反映客观现实而反映客观现实;它是有目的的,它是为感染人、打动人而写张三李四,为影响现实改造现实而反映现实的。
所以,艺术家又不能使自己完全化为张三李四,完全没入客观现实之中,而一定仍要不失“我”之所以为“我”,要能在对张三李四的描写中,在对客观现实的反映中,表现出“我”的鲜明的是非爱憎之感来。
所谓要在“非我”之中表现“我”,无非就是要在作品中渗入作者自己的思想感情。
而这,我认为正是创作的主要之点。
创作者正是为了要表现他对周围人物、对客观现实的态度,表现他对社会的歌颂或抗争,才来进行创作的。
所以,在创作活动中,决不可无“我”。
表演艺术最能说明这种创作的辩证法。
俗话说“装龙像龙,装虎像虎”。
演员演岳飞就应该像岳飞,演秦桧就应该像秦桧。
但只是像岳飞像秦桧,而不能也不应该使自己就变成岳飞,变成秦桧,演员不应该完全丢掉自己。

2019-2020学年福州第一中学高三下学期理科综合能力测试6(完卷时间:150分钟;满分:300分)第I卷(选择题共126分)【可能用到的相对原子质量】H-1N-14O-16Mg-24Al-27S-32Cl-35.5Ca-40Br-80一、选择题(本题共13小题,每题6分,共78分。
在每小题给出的四个选项中,只有一项是符合题目要求的。
)1.生物科学是实验科学,下面是某同学对生物科学的几个经典科学实验的分析,其中正确的是:()①德国科学家萨克斯将绿色叶片饥饿处理后进行半边遮光处理的实验,证明了光能转变为化学能储存在有机物中;②德国科学家恩格尔曼用水绵进行光合作用实验,证明了叶绿体是绿色植物进行光合作用的场所;③斯塔林、贝利斯通过对狗进行的一系列实验证明胰腺分泌胰液受体液调节,而不受神经调节;④施莱登、施旺创立的细胞学说揭示了细胞的多样性;⑤美国科学家鲁宾和卡门利用同位素标记法,证明了光合作用释放的氧来自水。
⑥摩尔根运用类比推理的方法证明了果蝇的白眼基因位于X染色体上A.①②③⑤B.②③⑤⑥C.①③⑥D.①②⑤2.下图是某植株叶片净光合速率(Pn:以CO2吸收速率表示)与胞间CO2浓度(Ci)的日变化曲线,以下分析正确的是:()A.与11:00时相比,13:00时叶绿体中合成C3的速率相对较高B.14:00后叶片的Pn下降,此时植株单位时间内积累的有机物的量开始减少C.17:00后叶片的Ci快速上升,导致叶片暗反应速率远高于光反应速率D.叶片的Pn先后两次下降,从光合作用过程的角度分析,主要限制因素是水分和光照强度3.科学家就米酵菌酸(某类细菌产生的物质)引起肾衰竭的问题进行了如下相关实验及分析:给从未接触过米酵菌酸的受试者皮下注射微量的米酵菌酸后,若出现局部皮肤红肿,则说明受试者对此毒素无免疫力;反之,则说明受试者体内含有足量的该毒素抗体。
下列相关叙述正确的是:()A.局部皮肤出现红肿说明该受试者对米酵菌酸过敏B.机体对米酵菌酸的免疫主要涉及到的特异性免疫是体液免疫C.米酵菌酸与其抗体结合形成细胞集团后,还需经过吞噬细胞的吞噬才可清除D.若受试者注射米酵菌酸后皮肤出现红肿,下次注射的红肿表现通常会更严重4.右图为人体某过程的变化曲线,下列有关叙述正确的是:()A.若该图表示正常人进食后血糖浓度的变化,则AB段血液中胰岛素含量上升,肝在BD段起了重要作用B.若健康人A点前从未接触过某病菌,该图A、C两点表示该病菌先后两次侵入此人体的时刻,则AB、CD段产生抗体的浆细胞都来自两种细胞的分化C.若该图表示正常人一天内的体温变化,则说明人的体温随环境温度的变化而波动D.若该图表示在温度交替变化的环境中健康人的皮肤血流量变化,则AB段感受刺激的是温觉感受器,此时血液中明显增多的激素是肾上腺素和甲状腺激素5.对基因进行编辑是生物学研究的重要手段,右图是对某生物B基因进行定点编辑的过程,该过程中用sgRNA可指引核酸内切酶Cas9结合到特定的切割位点,相关说法正确的是:()A.基因定点编辑前需要设计与靶基因部分序列完全配对的sgRNAB.核酸内切酶Cas9可断裂核糖核苷酸之间的化学键C.被编辑后的B基因因不能转录而无法表达相关蛋白质D.通过破坏B基因后生物体的功能变化可推测B基因的功能6.如图为某昆虫杂交实验示意图。

She dug into a boxand pulled out a baseball card. Shestopped for a moment and admiredthe picture. “Red Stocking B. B.Club of Cincinnati,” the card read,under the reddish-brown color photoof 10 men with their socks pulledup to their knees.As a collector and seller, it's her job tospot old items that might have value today,It’s what Bernice, 72, and her husband, Al Gallego, 80, have been doing since 1974 at their California antique store.This card, she figured, was worth selling on eBay. She took a picture, wrote a description and put it up for auction. She put a $10 price tag on it, deciding against$15 because it would have cost her an extra 20 cents. Later that night she got a few odd inquiries—someone wanting to know whether the card was real, someone wanting her to end the auction and sell him the card immediately.The card is actually 139 years old. Sports card collectors call the find "extremelyrare" and estimate the card could fetch five, or perhaps, six figures at auction.Just like that, Bemice is the least likely character ever for a rare-baseball card story."I didn't even know baseball existed that far back," Gallego says, "I don't think that I've ever been to a baseball game." The theory is that the card came out of a storage space they bought a few years back. It is not uncommon in their line of work to buy the entire contents of storage units for around $200.When she met with card trader Rick Mirigian, she found out what the card was—an 1869 advertisement with a picture of the first professional baseball team, the Cincinnati Red Stockings."When I came to meet her and she took it out of a sandwich bag and she was smoking a cigarette, I almost fainted," Mirigian says“They’ve uncovered a piece of history that few people will ever be able to imagine. That card is history.It's likeunearthing a Mona Lisa or a Picasso."24.What can we conclude from Paragraph3A.Bernice wanted to end the auction that night.B.Bernice decided to sell the card for $15.C.Bernice had to pay some fees for her card on eBayD.eBay charged her 20 cents for the card.25.Theunderlined word "fetch" in Paragraph 4 most probably means " ".A. go and bringB. be sold forC. add up toD. go down to26.From the passage, we may learn that .A.Bernice unexpectedly became the owner of the rare-baseball cardB.Bernice is the last person to purchase the rare-baseball cardC.Bernice didn't realize the value of the card until she put it up forauctionD.Bernice is a baseball fan27.What would be the best title for the passageA. Bemice Gallego—A Lucky CollectorB. Sports Card CollectorsC. The History of the Baseball CardD. A Surprisingly Valuable DiscoveryCResearchers in the field of psychologyhave found that one of the best ways to makean important decision, such as choosing auniversity to attend or a business to investin, involves the use of a decision worksheet.Psychologists compare the actual decisionsmade by people to theoretical ideal decisionsto see how similar they are. Supporters ofthe worksheet procedure believe that it willhelp people make optimal, that is, the bestdecisions. Although there are several changeson theexact forms that worksheets can take, they are all similar in their essential aspects. Worksheets require defining the problem in a clear way and then listing all possible solutions to the problem. Next, the related considerations that will be affected by each decision are listed, and the relative importance of each consideration or consequence is determined. Each consideration is assigned a numerical (数字的) value to reflect its relative importance. A decision is mathematically calculated by adding these values together. The alternative with the highest number of points comes out as the best decision.Since most important problems are multifaceted(多方面的), there are several alternatives to choose from, each with unique advantages and disadvantages. One of the benefits of a pencil and paper decision-making procedure is that it permits people to deal with more variables(可变因素) than their minds can generally comprehend and remember. On the average, people can keep about seven ideas in their minds at once. A worksheet can be especially useful when the decision involves a large number of variables with complex relationships. A realistic example for many college students is the question “What will I do after graduation” A graduate might seek a position that offers specialized training, pursue an advanced degree, or travel abroad for a year. A decision-making worksheet begins with a clear statement of the problem that will also help to narrow it. It is important to be clear about the distinction betweenlong-range and immediate goals because long-range goals often involve a different decision than short-range ones. Focusing on long-range goals, a graduating student might change the question above to “What will I do after graduation that will lead to successful career”28.Of the following steps, which occurs before the three other stepsin making a decision worksheetA.Listing the consequences of each solution.B.Calculating a numerical summary of each solution.C.Deciding which consequences are most important.D.Writing down all possible solutions.29.According to decision-making worksheet theory, an optimal decisionis defined as one that .A.has the fewest variables to consideres the most decision worksheetsC.has the most points assigned to itD.is agreed to by the greatest number of people30.The authordevelops the discussion in Para. 1 by means of .A.describing a processB.classifying types of worksheetsC.providing historical backgroundD.explaining a theory31.T he author states that “On the average, people can keep aboutseven ideas in their minds at once” in the last paragraph toexplain that .A.most decisions involve seven stepsB.human mental capacity has limitationsC.some people have difficulty making minor as well as majordecisionsD.people can keep more than seven ideas in their minds withpracticeDWhy Mars is New SettlementIs it possible to live on other planets The United States government is taking a serious look at the moon and Mars as potential places for future human settlement. The moon could serve as a training ground for later journeys to Mars. Currently, with Mars becoming the eventual long-term goal, serious questions exist as to whether the dangers of the settlement on the moon are too extreme and unnecessary.One major reason that the settlement on the moon is too dangerous is the difference between the atmosphere environment of the moon and Mars. Atmosphere is important because it protects humans and allother lives from a continuous attack of radiation caused by sources such as the sun. This radiation is especially dangerous to humans because it increases the risk of cancer and can negatively change DNA. The fact that the moon has no atmosphere can cause great harm to human beings. Although Mars’ atmosphere i s significantly thinner than Earth’s, at least it has one and would create some sort of protective barrier for humans.Another important characteristic for human settlement is natural resources like water, of which the moon is believed to have none. Mars, however, contains vast quantities of water ice, dry ice, and also snow. There is also sufficient evidence that water once existed at the surface of Mars and might return in the future if the planetwarms. With increased technologies, the potential for settlers to remain on Mars by being increasingly self-sufficient makes Mars a much more attractive goal as the space settlement than the moon.Future settlers will not only benefit from potential water on Mars; the planet is also rich in other natural resources such as oxygen, hydrogen, and minerals, which can be well used in productive ways. For example, hydrogen can be used as fuel, and it can be combined with nitrogen ( 氮气) to form new materials necessary for human settlement. Due to these advantages, Mars would be a more successful planet for exploration and settlement because it contains the basic resources necessary for humans to survive.Since the environment of Mars is more similar to that of Earth andit contains resources necessary to help life exist, it should be the only option for any kind of long-term human settlement. The settlement on Mars would not only be a milestone in space but also an excellent chance for mankind to improve itself from past adventures on Earth and preserve and make the best use of the natural resources Mars has to offer.32.According to Paragraph 2, the atmosphere on Mars would .A.change the DNA structure of humansB.measure the harmful radiation from spaceC.provide protection against dangerous effectsD.cause humans to be exposed to serious illnesses33.What can be inferred about water on MarsA.It is not present in a liquid state.B.It doesn’t exist in large quantities.C.It will bring potential dangers to settlers.D.It can be easily changed into liquid forms.34.The author believes that .A.exploration of Mars takes great riskB.natural resources on Mars last foreverC.settlement on Mars is perfectly acceptableD.Mars is more suitable for settlement than Earth35.Which of the following shows the developmentof ideas in the passage CP: Central Point P: PointSp: Sub-point(次要点) C:ConclusionA.
