One day, a traveler was walking near the top of a hill. He saw a little shepherd (牧羊人) boy with a group of sheep feeding around him.
As he came nearer he saw that the boy held a charred (烧焦的) stick in his hand, with which he was drawing something on a rock. The boy did not notice the stranger.
The stranger bent over him and looked at his picture, it was the picture of a sheep, and it was drawn so well that the stranger was filled with amazement.
The stranger's name was Cimabue. He was the most famous Italian painter of the time. He offered to take this little boy to Florence and teach him to be a great painter.
The boy's face shone with delight. “I should like to learn to do that，” he answered. “But I must do as Father says.”
“Let's go and ask him，” said Cimabue.
The boy was called Giotto Bondone. He worked for a rich man by taking care of his sheep. Giotto's father was working in the field.
“I know that the boy can draw picture s wonderfully well，” he said, feeling surprised at Cimabue's offer. “He does not like to do anything else. Yes, you may take him. Perhaps he will do well with you.”
In the city of Florence little Giotto learned so fast that he could soon paint as well as Cimabue himself.
One day, Cimabue was painting the picture of a man's face. Night came on before he had finished it. “I will leave it till morning，” he said.
The next morning, when he looked at the picture, he saw a fly on the man's nose. He tried to
brush it off, but it remained there. It was only a painted fly.
“Who has done this？” he cried.
Little Giotto came out from a corner, shaking. “I did it, master，” he said. He expected to be punished. But Cimabue only praised him for his great skill. “There are fe w men who can draw so good a picture of a fly，” he said.
25．Cimabue considered the picture on the rock ________.

Welcome to the future. It’s year 2050 and Scotland is now powered completely by“clean”energy.
Homes have entire roofs made of solar materials, rooms are kept warm by wallpaper, and people go to and from work in electric and hydrogen( 氢) cars.
Oil is still being found in the North Sea, but it’s not now only used to keep aircraft flying. And a new 500---mile underwater link with Iceland has been built to catch heat from the hot springs. There’s still a role for king coal—but the black diamonds are now environment---friendly.
People will be able to import the electricity they need and export any excess(超过的量) they make through rooftop windmills(风车). New technology will store electricity better and provide it on demand. Heat exchangers will provide heating and hot water.
Harmful carbon dioxide waste is being piped offshore to St Fergus and from there into some of the remaining oil—producing fields to be stored safely without entering the atmosphere. Gas remains the preferred energy source of industry and is now shipped in liquid form. But hydrogen is imported through pipelines from France and from a geothermal (地热的) plant in Iceland.
Hydrogen—fuelled cars have become popular. Electric bikes are common in cities using the new urban two—wheel network. Electric vehicles have become common, and their performances have been improved because of the developments in electrical drive technology like high—temperature super conducting motors. Many people leave their vehicles in a giant park where they can be recharged from the national electrical system . Oilseed rape (油菜) is widely grown to fuel some motors .
28．What does the underlined phrase in paragraph 2 mean ?
A. The hot springs
B. Oil
C. Coal
D.Oil
and coal
29．Which sources of energy play a more important role in people’s daily life in the future ?
A. Oil and coal
B. Hydrogen and gas
C. Electricity and gas
D. Solar energy and wind
30．The means of transport people use in 2050 do not include__________.
A. windmills
B. electric bikes
C. hydrogen—fuelled
D. aircraft cars 31．The passage is written to tell us in the future_____________.
A. life will be better and better
B. the energy will become cleaner and cleaner
C. people will use some new sources of energy
D. people will pay more attention to the environment
D
The "Thumbs-Up"
While Western culture has become used to the thumbs-up as a positive signal (probably coming from World War II pilots using the signal to communicate that they were "good to go" with ground crews), there are cultures where a thumbs-up may land you in trouble. In West Africa, as well as Greece, Italy and Middle East, the thumbs-up is pretty much the biggest insult(侮辱).
Rather more charming is a thumbs-up in Germany and in parts of Japan —they just see it as the hand signal for the number one.
The "A-OK"
This sign is mainly used by divers(潜水员)to mean "OK"(to prevent being confused with the thumbs-up sign, which means "rise"). Basically the meaning comes out as "great", or "completely fine". However, in a few countries in Euro
pe, people may think you’re telling them that you think they’re a 'zero’.
The "V Sign"
The sign comes in two formats: one with the palm faced outwards, and one with the palm inwards. In America they mean the same thing —"victory". However, if the outside of your hand is facing your target, you’re giving somebo dy a long-established insult in Great Britain and many English-speaking countries such as Australia, Ireland and New Zealand. Winston Churchill famously used the "incorrect" version of the V sign during the early years of the war, turning the outside inside later. The V sign is also considered rude in Italy.
The "Corna"
The corna hand gesture has most recently been adopted by fans of rock and heavy metal music. Nowadays many Americans use the gesture simply to mean "rock on", or in support of the University of Texas in Austin (known as the "Hook’em Horns"). Today it is still popular in Spain, Brazil and Slovakia (斯洛伐克) . Historically, however, the symbol possibly dates back to Ancient Greece.
32. Which of the following signs doesn’t have an insulting meaning?
A. The "Thumbs-Up".
B. The "A-OK".
C. The "V Sign".
D. The "Corna".
33. The pilots in World War II used to make the "Thumbs-Up" sign to show _________.
A. the plane was very good
B. the plane was ready to take off
C. they were going to land on the ground
D. they were thankful to the ground crews
34. What information can we get from the passage?
A. The "V Sign" was first used by Winston Churchill.
B. Italians often use the "Thumbs-Up" to praise others.
C. You are most likely to see the "Corna" in a heavy metal music concert.
D. The "A-OK" and the "Thumbs-Up" have the same meaning to divers.
35. If you travel abroad, you ’d better not use the "V Sign" in ______________.
A. Greece or Italy
B. Germany or Japan
C. Ireland or Italy
D. Spain or Brazil

pretty cake shop. When a tired-looking old man came in to buy a cake, I immediately helped him sat down in a chair and then brought him the cake. After he paid for them, I said thanks for him. He looked so happy that he praised me with a satisfying smile. From this, I learned: Be good to others or they'll be good to you.

43．A从下文可以看出这是一个完整的故事，所以用story。
44．C考查动词辨析。联系空后的to可推出：decide to“决定”；hope to“希望”；refuse to“拒绝”，只有prepare to do sth.(准备做某事)，符合题意。一群牧民在一整天的旅途后，很疲惫，准备搭帐篷(休息)。
45．C根据下文语境 a bunch of bright light可以推出他们“被光束包围”，故选surrounded。
46．A根据前面的looking forward to“(高兴地)盼望；期待”，我们可以推出牧民们带着极大的期望，盼望上帝能够给他们带来财富(第五段也有提示)。所以expectation最符合题意。
47．B根据上下文可知此处表示在天亮之前，所以用before。
48．B the number of“……的数目”；the amount of“……的数量(修饰不可数名词)”，而a bit of“少量(修饰不可数名词)”都不符合题意，所以只有a lot of“许多”正确。
49．D考查情态动词。根据上文maybe我们可以推出这里是表示不太有把握的判断，所以用may或might。
50．A考查动词辨析，根据上下文我们可以推出上帝应该是消失，不见了，所以用disappeared。
51．D根据下文语境可以看出他们的期待(上帝给他们带来财富)与现实(捡鹅卵石)相差很远，所以用disappointed“失望的”。
52．D根据上文语境，尤其是第一段的useless可知，这些牧民认为捡鹅卵石没有什么用处，所以用meaningless。
53．C in all“总共；总计”；at all“根本；全然”；after all“毕竟；终究”；above all“首先”，根据语境可知此处表示“这毕竟是上帝的意愿”，所以用after all。
54．A这里是as引导的让步状语从句，注意as引导让步状语从句时必须要倒装。
55．B根据第四段中的collect，我们可以推出这里用picking over“用心挑选；筛选”。
56．A examine“检查”；search“寻找”；seek“寻找”；watch“观看”。根据语境“当他们查看这些鹅卵石的时候，发现它们都变成了钻石”可知，examining正确。
65．to enjoy 根据动词aim的用法aim to do sth.“意欲做某事”可知该空填不定式作宾语。
66．by根据固定短语by coincidence“巧合地”可知该空填介词by。
67．a根据固定短语a great deal “非常地”可知该空填不定冠词a。
68．to look根据动词attempt的用法attempt to do sth.“试图做某事”，可知该空不定式作宾语。
69．appealed所给词在句中作谓语且表示过去的动作，故填一般过去式。
70．who先行词是Grandma Moses，空格后面的从句中缺少主语，故该空填关系代词who。

My_opinion_on_copying_others'_homework
It_is_known_to_us_all_that_some_students_copy_others'_homework. As students, we learn many subjects and have to do plenty of homework both at home and at school. And sometimes we have some homework which is too difficult for us. On the other hand, some students are lazy, and are not interested in their lessons. They don't work hard. In order to finish the assignments and
please their teachers and parents, some students copy others' homework.
In my opinion, it is wrong to copy others' homework because it breaks the rules of the school. Even though we have trouble doing our homework, we can ask our classmates or teachers for help. Students should be honest and try to finish our homework by ourselves instead of by copying.

湖南省长郡中学2017-2018学年高二12月月考(第二次模块检测） 湖南省长郡中学2017-2018学年高二12月月考(第二次模块检测） 第卷（阅读题） 一、现代文阅读 阅读下面的文字，完成下面小题。 700多年来，中国历史上出现了两个异族入主中原的王朝，即蒙元和满清。二者都是文明相对落后的民族靠武力征服先进民族而建立的。蒙古人在入主中原后，仍想以落后的制度继续统治中华；而满清只以武力征服了中原的土地，自己的内心却被汉族的制度文化折服。因此，元朝虽强大一时，却不足百年；而清朝享祚近三个世纪，确实发人深省。。 从民族政策来看,元朝按照种族和地域，把全国人口分为四等：一等蒙古人,二等色目人,三等汉人,四等南人。至治二年，禁汉人执兵器出猎，禁习武艺。至元三年，禁汉人、南人学习蒙古和色目文字。同年，右丞相伯颜向皇帝建议，屠杀张、王、李、赵、刘等五姓汉人，好在顺帝没有同意。同年，禁止汉人、南人、高丽人持兵器养马。早先，中使别迭等就向成吉思汗建议：虽然得到汉人，也没有什么用处，不如将其斩尽杀绝，只要留下空地，使草木畅茂，我们可以改作牧场。若不是耶律楚材极力劝阻，此种族灭绝的建议就可能成为国策。据马可·波罗记载：所有的中国人都厌恶大可汗（元世祖）的政体，因为他所派地方行政首长多为鞑靼人（蒙古人），尚有色目人，其视中国人（原来中原及江南的中国人）为奴隶，使之无法容忍。 而清入关后，立即从满蒙一家向满汉一体。康熙十九年，谕绿旗部队：汉族叛乱只用汉兵平剿。清朝作战皆重用汉人。满族人虽然武力征服汉人，却在精神上崇尚汉化。满汉民族起码在法律上平等。满人世袭旗籍，汉人和蒙古人照样可投旗入籍。在对待汉语的态度上,元代诸帝多不习汉文。世祖之时江淮一行省无一人通文墨者。有的蒙古贵族到地方任官，执笔署事，写七字之钩不向右而向左，见者为笑。陶宗仪《辍耕录》载曰，今为官者蒙古色目人多不能执笔花押，例以象牙或木刻而印之，宰辅及近侍官至一品者，得旨则用玉图书押字。元朝的儒臣为向皇帝进讲，须先翻译蒙古文。世祖虽有一定程度的汉语水平，仍不能脱离翻译。只有最后两代皇帝——文宗和顺帝汉语尚可。而清朝早在入关之前49年，龚正六（浙江绍兴府会稽县人）就给建州女真部首领努尔哈赤当师傅，并兼任太祖诸子的老师，受到最高的礼遇。太祖亲信侍卫中有许多汉族读书人。太祖精通汉语，言必称汉唐，奉明制为圭臬。 太祖身边尚须翻译，顺治皇帝已经无须翻译。康熙、乾隆本身就是精通琴棋书画的汉学家。少年康熙只有在亲切地称呼外国传教老师汤若望为玛珐时，有使用满语的记录。雍正几乎全用汉语，只有看到八弟胤禩、十四弟胤禟谋逆罪状时大大震怒，才失口用满语大骂塞斯黑阿其那（意为猪狗）。后世皇帝仅在个别称谓上保留使用满语的习惯。清皇室学校把把汉语作为必修课程，诸皇子的老师都是当朝有名的国学大家。整个满清是满人保持主动汉化的态势，并且比前朝的国学氛围更浓。 （选自王丹誉《元清两代制度得失》） 1. 下列关于原文内容的表述，不正确的一项是（） A. 蒙古人和满族人都是凭借武力入主中原，不同的是,蒙古人仍想以落后的制度来治理天下，结果不到一个世纪，元朝就宣告灭亡。 B.

长郡中学2018-2019学年度第二第一学期入学考试 物理 一、选择题（本题包括12小题，每小题4分，共48分，每小题给出的四个选项中，1~8题只有一个选项正确，9~12题有多个选项正确，全部选对的得4分，选对但不全的得2分，有选错的得0分） 1.一质点沿轴正方向做直线运动，通过坐标原点时开始计时，其的图象如图所示，则（） A. 质点做匀速直线运动，速度为0.5m/s B. 质点做匀加速直线运动，加速度为0.5m/s2 C. 质点在第1s内的平均速度0.75m/s D. 质点在1s末速度为1.5m/s 【答案】D 【解析】 【详解】由图得：=0.5+0.5t。根据匀变速直线运动的位移公式x=v0t+at2，得：=v0+at，对比可得：v0=0.5m/s，a=1m/s2，则质点做初速度为0.5m/s、加速度为a=1m/s2的匀加速直线运动，故AB错误；质点在第1s末速度为：v=v0+at=0.5+1=1.5m/s。则质点在第1s内的平均速度为：，故C错误，D正确；故选D。 【点睛】本题的实质上是速度-时间图象的应用，关键要运用数学知识得到函数式，分析质点的运动性质，再根据图象读取有用信息． 2.一质点做匀加速直线运动时，速度变化Δv时发生位移x1，紧接着速度变化同样的Δv时发生位移x2，则该质点的加速度为( ) A. B. C. D. 【答案】D 【解析】
【分析】 根据匀变速直线运动的速度位移公式，结合两段过程中速度的变化量相等，联立求出质点的加速度． 【详解】设匀加速的加速度a，物体的速度分别为v1、v2和v3；据运动学公式可知，v22?v12＝2ax1，v32?v22＝2ax2，且v2-v1=v3-v2=△v；联立以上三式解得：a=。故选D。 3.如图所示为两个等量点电荷的电场线，图中A点和B点、C点和D点皆关于两电荷连线的中点O对称，若将一电荷放在此电场中，则以下说法正确的是（） A. 电荷在O点受力最大 B. 电荷沿直线由A到B的过程中，电场力先增大后减小 C. 电荷沿直线由A到B的过程中，电势能先增大后减小 D. 电荷沿直线由C到D的过程中，电场力先增大后减小 【答案】D 【解析】 试题分析：根据电场线的疏密特点，在AB直线上，O点电场强度最小，则受到电场力最小，而在CD直线上，O点的电场强度最大，则受到电场力最大，因此电荷在0点受力不是最大，故A错误．根据电场线的疏密可知，从A到B的过程中，电场强度先减小后增大，则电场力也先减小后增大；同理从C到D的过程中，电场强度先增大后减小，则电场力也先增大后减小．故B错误，D正确，电荷沿直线由A到B的过程中，无法确定电荷做功的正负，因此无法确定电势能变化，故C错误．故选D。 考点：电场线；电场强度 【名师点睛】常见电场的电场线分布及等势面的分布要求我们能熟练掌握，并要注意依据电场线的疏密来判定电场强度的大小，同时注意等量异号电荷形成电场的对称性．加强基础知识的学习，掌握住电场线的特点，即可解决本题。 4.如图所示，在光滑绝缘水平面上的M、N两点各放有一个电荷量分别为+q和+2q的完全相同的金属A、B.在某时刻，使 A、B 以相等的初动能 E 开始沿同一直线相向运动（设这时它们
