2019-2020学年邯郸县第三中学高三英语下学期期末考试试题及答案第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项AIn his 402nd anniversary year, Shakespeare is still rightly celebrated as a great language master and writer. But he was not the only great master of play writing to die in 1616, and he is certainly not the only writer to have left a lasting influence on theater.While less known worldwide, Tang Xianzu is considered one of Chinas greatest playwrights and is highly spoken of in that country of ancient literary and dramatic traditions.Tang was born in 1550 inLinchuan,Jiangxiprovince. Unlike Shakespeare's large body of plays,poems and sonnets (十四行诗), Tang wrote only four major plays: The Purple Hairpin, Peony Pavilion (《牡丹亭》), A Dream under the Southern bough, and Dream of Handan. The latter three were constructed around a dream narrative, a way through which Tang unlocked the emotional dimension of human desires and ambitions and explored human nature beyond the social and political limits of that time.Similar to Shakespeare, Tang's success rode the wave of a renaissance (复兴) in theater as an artistic practice. As in Shakespeare'sEngland, Tang's works became hugely popular inChinatoo. During Tang'sChina, his plays were enjoyed performed, and changed. Kunqu Opera, a form of musical drama, spread from southernChinato the whole nation and became a symbol of Chinese culture. Combining northern tune and southern music, kunqu Opera was known for its poetic language, music, dance movements and gestures. Tang's works benefited greatly from the popularity of kunqu Opera, and his plays are considered classics of kunqu Opera.While Tang and Shakespeare lived in a world away from each other, there are many things they share in common, such e humanity of their drama, their heroic figures, their love for poetic language, a lasting popularity and the anniversary during which we still celebrate them.1. Why is Shakespeare mentioned in the first paragraph?A. To describe Shakespeare's anniversary.B. To introduce the existence of Tang Xianzu.C. To explain the importance of Shakespeare.D. To suggest the less popularity of Tang Xianzu.2. What's possibly one of the main theme of Tang's works?A. Social reality.B. Female dreams.C. Human emotions.D. Political environment.3. What does the author mainly tell us in Paragraph 4?A. The influence of Kunqu Opera on Tang's works.B. Tang's success in copying Shakespeare's styles.C. The way Kunqu Opera became a symbol of Chinese culture.D. Tang's popularity for his poetic language and music.BThey are smart. They know how to steal. They know how to find food. They know how to intimidate(恐吓) . Who are they? They are macaque monkeys. They have taken over the old city ofLopburiinThailand. About 8,400 of them are in the center of the city. They roam(漫游) neighborhoods in groups. Dozens of businesses in Lopburi are closing. They include a music school, a gold shop, a barber, a cellphone store and a movie theatre. The Buddhist culture believes reducing the number of monkeys would disturb spiritual well-being.The monkeys were not always such a hazard. They attracted tourists. Buddhists thought feeding them was a good deed. Now times have changed. Recently, the coronavirus made things worse. There are fewer tourists, which means that travelers give less food to the monkeys. Over the years, the monkeys moved into empty buildings. They trashed whatever they came across. They ripped(扯掉) antennas and windshield wipers off parked cars. What happens when monkeys come into contact with humans? An observer said that years ago the monkeys were fewer, biggerand healthier. Their fur was shiny and thick. They kept to the temples,as well as the ruins of the ancient Khmer civilization.Then tourists came with easy and unhealthy food. Along with bananas and citrus(柑橘), the macaques feasted on junk food. An observer said, “The monkeys are never hungry. They are just like children who eat too much KFC. ” Compared with the monkeys of the forest, their urban counterparts have less muscle. They have more hypertension and blood disease. Their fur has thinned. Some have gone bald. With so much food available,they have more time to breed and to give birth. Their population has exploded. “These monkeys were here before us,” a man said. A juvenile macaque tugged(拽) his trousers demanding a treat. “We have to adapt to them,not the other way around. ”4. Why are macaque monkeys so popular in Lopburi inThailand?A. Because they are smart and know how to steal.B. Because they have taken over the old city ofLopburiinThailand.C. Because they are symbols of spiritual well-being in the Buddhist culture.D. Because 8,400 of them are in the centre of the city and roam everywhere.5. In what way has tourism influenced the macaque monkeys?A. The monkeys are bigger and healthier.B. The monkeys like eating KFC food.C. The monkeys have suffered from more diseases.D. The monkeys are subject to birth control.6. What does the underlined word “counterparts” in the last paragraph refer to?A. Monkeys.B. Tourists.C. Buddhists.D. Children.7. It can be inferred from what the man said that ________.A. monkeys are ancestors, so humans should adapt to monkeysB. humans should regard monkeys with awe and respectC. monkeys should be forced to follow rulesD. humans should give monkeys whatever they wantCThe idea of low material desire, low consumption and refusing to work, marry and have children, concluded as a “lying down” lifestyle, recentlystruck a chord withmany young Chinese who are eager to take pause to breathe in this fast-paced and highly-competitive society.Many millennials (千禧一代) and generation Zs complained to the Global Times that burdens, including work stress, family disputes (纷争) and financial strains, have pushed them “against the wall”. They said they hate the “involution (内卷),” joking that they would rather give up some of what they have than get trapped in an endless competition against peers.“Instead of always following the ‘virtues’ of struggle, endure and sacrifice to bear the stresses, they prefer a temporary lying down as catharsis (宣泄) and adjustment,” said a scholar. “It is no wonder that some young people, under the growing pressures from child-raising to paying the mortgage (按揭) today, would try to live in a simple way and leave the worries behind.”Interestingly, the majority of millennials and Gen Zs reached by the Global Times, who claim to be big fans of the lying down philosophy, acknowledged that they only accept a temporary lying down as a short rest. It is true that with the great improvement of living conditions, some Chinese youth have partially lost the spirit of hardshipand are not willing to bear too much hard work. But in fact, lying down is not entirely comfortable. Young people who lie down always feel guilty about their constant loss of morale (士气) far beyond their reach.“Young people on campus have both aspirations and confusion about their future, but most of us have rejected setting ourselves up in chains to waste opportunities and challenges,” a postgraduate student told the Global Times. “It’s no use running away. I have to ‘stand up’ and face the reality sooner or later.”8. What does the underlined phrase in paragraph 1 mean?A. Warned.B. Criticized.C. Touched.D. Amused.9. What might have caused the “lying down” lifestyle among the young?A. Improvements in living conditions.B. Growing pressure from family and social life.C. Increasing material possessions from families.D. Temporary adjustment to failure in competitions.10. What’s the scholar’s attitude toward the “lying down” group?A. Understanding.B. Intolerant.C.Supportive.D. Unclear.11. What can be inferred about the young generation from the text?A. They never really drop their responsibilities.B. They really enjoy the “lying down” lifestyle.C. They find their dreams far beyond their reach.D. They would rather escape than take challenges.DA male tiger was rescued in Mishan city, Northeast China's Heilongjiang province, on Friday. A tiger was recently seen on the Siner Russian border(边界),but there is no evidence to suggest this is the same tiger or that it had lost its way from Russia.Wherever it may have come from, cross-border protection of endangered species is a problem. According to Ma Jianzhang, a senior wild animal researcher in China, tigers know no borders, which have been built to stop humans from illegally crossing over. However, these borders also stop the free movement of tigers, thus preventing their breeding(繁殖)and exchange of genes.The Sino-Russian border alsocomes in the way ofprotecting tigers in the region. Data show about 500 to 550Siberian tigers, or over 90 percent of the species, live in the wild in Russia; 27 live in the wild in China, and 50 inthe border region. Sometimes tigers lose their way across the border and that is hindering(妨碍)efforts to stop illegal hunting and protecting them.Fortunately, both China and Russia have realized this problem and are working toward solving it. As early as 2010, the two countries established a cross-border protection network aimed at strengthening communication on protecting tigers in the northeast. The countries have also held anti-poaching(反偷猎)activities together. In 2019, two national parks from the two countries signed a three-year deal to share research data on tigers, greatly improving the living conditions of Siberian tigers in the wild.However, much more needs to be done to protect the species. It is necessary to combine the tiger protection areas in the two countries. That will require greater efforts from both sides and some difficulties might remain even then. Fortunately, both countries have been taking effective measures to provide the endangered species a better home.12. What's the original purpose of setting up the Sino-Russian borders?A. To ban people from illegal crossings.B. To help protect tigers in the region.C. To protect tigers from losing their way.D. To stop tigers' breeding and exchange of genes.13. What does the underlined phrase “comes in the way of” probably mean?A. keeps from.B. is on the way toC. is aimed atD. keeps up14. What is the focus of Paragraph 4 ?A. Recent studies and researches on tigers.B. Joint efforts by China and Russia to protect tigers.C. The possible effects of establishing a networkD. Reasons for improving the living conditions of tigers.15. What's the author's purpose in writing the text?A. To inform the possible dangers of tiger protection.B. To cover the news about a missing tiger on the border.C. To put forward suggestions on finding the missing tiger.D. To report the problems and measures of cross-border tiger protection.第二节(共5小题;每小题2分,满分10分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。

.【答案与解析】1.答案:B解析:解:设菱形的面积为S,两条对角线的长分别为x、y,则有,1xy=S,2∴y=2S,x而菱形的面积为定值,即2S为定值,是常数不变,所以y是x的反比例函数,故选:B.构造菱形的对角线与面积之间的函数关系式,根据关系式进行判断即可.本题考查反比例函数关系,理解反比例函数的意义是正确判断的前提.2.答案:B解析:解:取AB的中点O,过D作DE⊥AB于E,如图2所示:由题意得:OA=OB=AD=BC,设OA=OB=AD=BC=r寸,CD=1寸,则AB=2r(寸),DE=10寸,OE=12∴AE=(r−1)寸,在Rt△ADE中,AE2+DE2=AD2,即(r−1)2+102=r2,解得:r=50.5,∴2r=101(寸),∴AB=101寸,故选:B.取AB的中点O,过D作DE⊥AB于E,根据勾股定理解答即可得到结论.本题考查了勾股定理的应用,弄懂题意,构建直角三角形是解题的关键.3.答案:D解析:试题分析:根据二次根式的加减法对A进行判断;根据二次根式的乘法法则对B进行判断;根据二次根式的性质对C进行判断;根据二次根式的除法对D进行判断.A、√2与2√3不能合并,所以A选项错误;B、原式=2√2,所以B选项错误;C、原式=|−3|=3,所以C选项错误;D、原式=√27÷3=3,所以D选项正确.故选D.4.答案:D解析:解:∵样本x1,x2,x3,…,x n的平均数为10,方差为4,∴样本x1−3,x2−3,x3−3,…,x n−3的平均数为7,方差为4,众数和中位数变小.故选:D.利用平均数、中位数、众数和方差的意义进行判断.本题考查了方差:一组数据中各数据与它们的平均数的差的平方的平均数,叫做这组数据的方差.方差是反映一组数据的波动大小的一个量.方差越大,则平均值的离散程度越大,稳定性也越小;反之,则它与其平均值的离散程度越小,稳定性越好.也考查了平均数、众数和中位数.5.答案:A解析:解:设正比例函数解析式为:y=kx,将点A(3,−6)代入可得:3k=−6,解得:k=−2,∴正比例函数解析式为:y=−2x,将B(−m,4)代入y=−2x,可得:2m=4,解得m=2,故选:A.运用待定系数法求得正比例函数解析式,把点B的坐标代入所得的函数解析式,即可求出m的值.本题考查了一次函数图象上点的坐标特征.解题时需灵活运用待定系数法求出函数解析式,然后将点的坐标代入解析式,利用方程思想解决问题是解本题的关键.6.答案:B解析:解:如图,AQ=AM1,AQ=AM5,AQ=AM2,QA=QM4,AM3=QM3,故坐标轴上的点M恰使△MAP、△MAQ均为等腰三角形,则满足条件的点有5个,故选:B.根据等腰三角形的性质即可得到结论.此题主要考查等腰三角形的性质和坐标与图形的性质,解答此题的关键是利用勾股定理求出OP的长,此题难度不大.7.答案:A解析:解:由折线图知:1日用水5吨,二日用水7吨,三日用水11吨,四日用水3吨,5日用水9吨,=7,数据5、7、11、3、9的平均数是5+7+11+3+95中位数是7,由于各数据都出现了一次,故其众数为5、7、11、3、9.[(5−7)2+(7−7)2+(11−7)2+(3−72)+(9−7)2]方差是S2=15=8.综上只有选项A正确.故选:A.由折线图得到相关五天的用水数据,计算这组数据的平均数、中位数、众数、方差,然后判断得结论.本题考查了折线图、平均数、中位数、众数及方差等知识,读折线图得到用水量数据是解决本题的关键.8.答案:C解析:解:因为√12+√y=√27,所以√y=√27−√12=3√3−2√3=√3,所以y=3.故选:C.根据二次根式的加减法计算即可.本题考查了二次根式的加减法,解题的关键是熟练掌握二次根式的加减法法则.9.答案:A解析:解:①不正确;图形中全等的三角形有四对:△ABC≌△ADC,△AOB≌△COB,△AOE≌△BOF,△BOE≌△COF;理由如下:∵四边形ABCD 是正方形,∴AB =BC =CD =DA ,∠BAD =∠ABC =∠BCD =∠D =90°,∠BAO =∠BCO =45°,在△ABC 和△ADC 中,{AB =ADamp; BC =DCamp; AC =ACamp; , ∴△ABC≌△ADC(SSS);∵点O 为对角线AC 的中点,∴OA =OC ,在△AOB 和△COB 中,{OA =OCamp; AB =CBamp; OB =OBamp; , ∴△AOB≌△COB(SSS);∵AB =CB ,OA =OC ,∠ABC =90°,∴∠AOB =90°,∠OBC =45°,又∵∠EOF =90°,∴∠AOE =∠BOF ,在△AOE 和△BOF 中,{∠OAE =∠OBF =45°amp; OA =OBamp; ∠AOE =∠BOF amp; , ∴△AOE≌△BOF(ASA);同理:△BOE≌△COF ;②正确;理由如下:∵△AOE≌△BOF ,∴OE =OF ,∴△EOF 是等腰直角三角形;③正确.理由如下:∵△AOE≌△BOF ,∴四边形OEBF 的面积=△ABO 的面积=14正方形ABCD 的面积; ④正确.理由如下:∵△BOE≌△COF ,∴BE =CF ,∴BE +BF =CF +BF =BC =AB =√2OA ;。
