2020 学年第一学期9十1高中联盟期中考试高二年级历史学科试题一、选择题（本大题共35题，每小题2分，共70 分。

每小题列出的四个备选项中只有一个是符合题目要求的，不选、多选、错选均不得分）1.下表是英、法、德、美工业产量排位与殖民地占有比较表，从下表中可以得出信息有①第二次工业革命使列强实力对比发生改变②列强经济实力与所占殖民地面积出现倒挂现象③国际格局已经发生根本性变化④20世纪初的世界被列强瓜分完毕A.①②B. ①③C. ②③D.②④2."军备竞赛首先表现为军费快速增长。

1883年—1908 年间，欧洲大国的军费开支平均每年增长3.25%；1908年—1913年间，平均每年增长9.92%。

到战前的1913年，德国军费开支超过20 亿马克，占国家总预算的一半；法国为15 亿法郎，占国家总预算的38%"。

关于对战前快速增长的军费开支为代表的的军备竞赛，下列观点错误的是A.一大批新式武器问世，对各国的军备竞赛产生深远的影响B. 帝国主义争霸是这场军备竞赛的原动力C.德国、法国军费开支巨大，说明两国是两大军事集团的核心力量D. 列强间的军备竞赛使欧洲处于战争爆发的前沿3.《一战全史》中"此后战争虽然持续了4年之久，德国有时也取得了一些战术上的胜利，但它的战争计划已在□□□战役中彻底破产。

德皇和毛奇在6周内击败法军，灭亡法国，成为欧洲和世界霸主的美梦，消失在□□□的波涛里，成了梦幻泡影。

"材料中的□□□是指A. 凡尔登B.马恩河C. 索姆河D. 兴登堡防线4.《第一次世界大战——大参考》写到"有些人认为，凡尔登是被索姆河战役拯救的。

从某种意义上讲，这种说法有一定的道理。

1916年7月，就在凡尔登城下的浴血厮杀进入白热化时候，索姆河两岸又燃起了战火，英法军队向德军发动了大规模进攻，这就是持续4个月之久，惨烈程度甚于凡尔登的索姆河战役。

在索姆河发动大规模攻势，是协约国集团预定的1916年战略进攻计划的一部分。

Passages(A)Massive changes in all of the world's deeply cherished sporting habits are underway.Whether it's one of London's parks full of people playing softball, and Russians taking up rugby,or the Superbowl rivaling the British Football Cup Final as a televised spectator event in Britain,the patterns of players and spectators are changingbeyond recognition. We are witnessing a globalization of our sporting culture.That annual bicycle race, the Tour de France, much loved by the French is a good case in point. Just a few years back it was a strictly continental affair with France, Belgium and Holland,Spain and Italy taking part. But in recent years it has been dominated by Colombian mountain climbers, and American and Irish riders. The people who really matter welcome the shift toward globalization. Peugeot, Michelin and Panasonic are multi-national corporations that want worldwide returns for the millions they invest in teams. So it does them literally a world of good to see this unofficial world championship become just that.This is undoubtedly an economy-based revolution we are witnessing here, one made possible by communications technology, but made to happen because of marketing considerations.Sell the game and you can sell Coca Cola or Budweiser as well.a American football has been sold to Europe is a good example ofhow all sports will develop. The aim of course is not really to spread the sport for its own sake, but to increase the number of people interested in the major money-making events. The economics of the Superbowl are already astronomical. With seats at US$125, gate receipts alone were a staggering $10, 000, 000. The most important statistic of the day, however, was the $100, 000, 000in TV advertising fees. Imagine how much that becomes when the eyes of the world are watching.So it came as a terrible shock, but not really as a surprise, to learn that some people are nov suggesting that soccer change from being a game of two 45-minute halves, to one of fou25-minute quarters. The idea isunashamedly to capture more advertising revenue, without giving any thought for the integrity of a sport which relies for its essence on the flowing nature of the action.Moreover, as sports expand into world markets, and as our choice of sports as consumers also grows, so we will demand to see them played at a higher and higher level. In boxing we have already seen numerous, dubious world title categories because people will not pay to see anything less than a "World Title" fight, and this means that the title fights have to be held in differe countries around the world!56.Globalization of sporting culture means that___________A.more people are taking up sportsB traditional sports are getting popularC.many local sports are becoming internationalD. foreigners are more interested in local sports57. Which of the following is NOT related to the massive changes in the world's deeply cherished sporting habits?A.Good economic returns.B.Revival of traditional games.C. Communications technology.D. Marketing strategies.58. The author's attitude towards the suggestion to change soccer into one of four 25-minut quarters is______.A. favorableB. neutralC. reservedD. critical59. This passage mainly discusses_.A.the commercialization of sporting cultureB.the worldwide popularization of sportsC.the speculation in sporting eventsD.the restoration of sportsmanship(B)We asked you to________in 50 words or fewer. Once again, you didn't disappoint us.Here are our favourites, Which one do you like the best? Write and let us know.[1] My uncle has a 1974 Ferrarl Dino 308-'a thing of beauty,a joy forever', a poet once said. It's the perfect balance of engineering and design. The noise it makes as it pulls away, sets my heart racing. A flash of Ferrari red and it's gone.[2] Fading light. The last gasps of the day. On Earth, colours lose their hold as the sky above drains them. Crimson, rose, blood red. On Earth, I watch in amazement. The sun takes its farewell and dips behind the horizon. I leave, wondering what new beauties the day to come will bring[3] He turns, he stops, he turns and runs, he stops and turns againNo two moves are the same.He looks up, he looks down.He looks forward, he looks round.Will he pass? Will he shoot? Will he turn again?[4] As I watch my cat feed her hungry kittens, all eight of them, each fighting for a space, I think about the miracle of life---how well it all works, how well it all fits together. Does anything get perfect?[5] I'm sitting here, head in hand. There is no room left in my head. It's ready to explode.And then the bell sounds, loud and welcome. The sound echoes... echoes through the corridors.Happy children put downtheir pens and wait for the words, simple but beautiful:'Off you go.'[6] I live by the sea. Where else is there to live? The sea fills my heart with joy. A big blu expanse of happiness, The crashing waves, obeying no one, come and then go. I always return to the sea. It knows the answers before I even ask the questions[7]'Hello,I'm home.'It brings a smile to my face when I hear my wife's voice.I look up and she's there. Has she walked out of a painting?

In Post 5, the writer is actually talking about_.A.his/her noisy kidsB.the power of musicC.a terrible explosionD.the time when school is over(C)For the most part, it seems, workers in richer countries have little to fear from globalization. And a lot to gain. But is the same thing true for workers in poor countries? The answer is that they are even more likely than their rich-country counterparts tobenefit，because they have less to lose and more to gain Traditional economics takes an optimistic line on integration(整合）and the developing countries. Openness to foreign trade and investment should encourage capital to flow to poor economies. In the developing world, capital is scarce, so the returns on investment there should be higher than in the industrialized countries, where the best opportunities to make money by adding capital to labour have already been used up. If poor countries lower their barriers to trade and investment, as the theory goes, rich foreigners will want to send over some of their capital.If this inflow of resources arrives in the form of loans or portfolio investment(组合投资）,it will top up domestic savings and loosen the financial restriction on additional investment by local companies. If it arrives in the form of new foreign-controlled operations, FDI, so much the better this kind of capital brings technology and skills from abroad packaged along with it, with less financial risk as well. In either case, the addition to investment ought to push incomes up, partly by raising the demand for labour and partly by making labour more productive.This is why workers in FDI-receiving countries should be in an even better position to profit from integration than workers in FDI-sending countries. Also, with or without inflows of foreign capital, the same gains from trade should apply in developing countries as in rich ones. The gains from trade logic often arouse suspicion, because the benefits seem to come from nowhere. Surely one side or the other must lose. Not so. The benefits that a rich country gets through trade do not come at the expense of its poor country trading partners, or vice versa. Recall that according to the theory, trade is a positive sum game. In all thesetrades, both sides-exporters and importers,borrowers and lenders, shareholders and workers can gain.63. Why are workers in poor countries more likely to benefit from the process of globalization?A. They can get more financial aidB . They have nothing to loseC. They have less to lose and more to gain.D. They can get more chances to gain a good job.64. What can be the final result of the inflow of the resource?A. It will top up domestic savings.B. It will loosen the financial restriction.C.It will push people's incomes up.D. It will bring technology and skills from abroad.65. What can we know from the last paragraphA.Poor countries get the most profit during the process of trade.B. Rich countries get profit from trade at poor countries' expense.C.Poor countries get more profit from trade than rich ones.D.All aspects involved in the trade can get benefit.66. Which can be the most appropriate title for this passage?A.Benefited or HurtB.Who Benefits the MostC.Helping the PoorD.The Inflow of ResourcesSection C(8%)Directions: Complete the following passage by using the sentences given below. Each sentence can be used only once. Note that there are two more sentences than you need.A. What we wear can reflect our skin colour.B. Other participants wore their normal clothes.C. The clothes we wear can affect our behavior.D. Some experts believe that the participants with white coats are more likely to be more creative.E. For example, we should choose a look that makes us feel more creative and happy.F. Galinsky and Adams think that the white coats made the participants feel more confident and careful .The science of styleDeciding what to wear in the moming is a challenge for some people. We often worry about what others will think of us because of our clothes. But researchers are beginning to think that our wearing has an equally powerful effect on how we see ourselves.Scientists Adam Galinsky and Hajo Adams report that there is science behind our style. In their research, Galinsky and Adams had some participants wear white lab coats similar to the ones scientists or doctors wear. ____67______The participants took a test that measured theirability to pay attention. The people wearing the white coats performed better than the people in regular clothes.____68____The researchers also believe that other kinds of "symbolic" clothescan influence the behavior of the people wearing them. A police officer's uniform or a judge's robe, for example, increases the wearer's feeling of power or confidence. And in workplaces that have a dress code,"symbolic"clothes may also affect how well employees do their jobs.Fashion blogger Jessica Quirk believes that our clothes greatly affect how we feel about ourselves. On her blog called"What I Wore," Quirk posts a photo of what she's wearing every day.She says that people should pay more attention to what they wear_____69______ One way to do this at work is to "dress up for the exciting job we want," she says, "not the boring job we have."Another way is to wear special clothes that mean something to us. For example, Quirk wears one pair of shoes to all her important meetings. They are her "lucky" shoes.As Quirk points out-and as researchers have discovered-our clothes are "like our second skin."___70____They can also tell the world something about us, without us having to say a word.IV.Summary Writing(10%)Directions: Read the following passage. Summarize in no more than 60 words the main idea of the passage and how it is illustrated. Use your own words as far as possible.It's not piano lessons or dance classes. Nowadays, the biggest extra-curricular activity is going to a tutor. "I spend about 800 Canadian dollars a month on tutors. It's costly," says Pat, a mother in Canada. However, she adds, "after finding out half my daughter's class had tutors, I felt like my child was going to fall behind because everyone else seemed to be ahead."Shelley, a mother of three, also has tutors constantly coming in and out of her home. "When I used to sit down with my children, it was hard to get them focused. I was always yelling. When I got a tutor once a week, they became focused for one entire hour and could get most of their homework done."Tutoring isn't simply a private school phenomenon. Nor is it geared(适应，满足）only toward lower-achieving students. In Canada alone, seven percent of high school students reported using a tutor in 2010. That increased to 15 percent last year.Overall, parents hire tutors because they are worried schoolsare not meeting their expectations, but there is also a cultural shift. A special value is placed on education in Asia, where tutoring is viewed as an extension of the school day. As a large number of Asians emigrated to the West over the recent years, their attitudes towards education have had an impact.Another reason for the growth in business is parental frustration and their packed schedules. "A lot of parents just don't have time to help their children with homework," says Julie Diamond,president of an American tutoring company."Others couldn't help their children after Grade 3."There has been a shift in the attitudes, too. "Children used to get bullied for having a tutor,"Diamond says. "Now it's becoming the norm to have one."Children don't seem to mind that they have a tutor. One parent feels surprised that so many of her child's classmates have tutors. "For the amount we pay in tuition, they should have as much extra help as they need," she says. Still, she's now thinking of getting a tutor. Why? Her daughter has actually asked for one.V.Translation(15%)Directions: Translate the following sentences into English, using the words given in the brackets.72、你越努力，收获就会越大。
