It was a warm April day when a big fat envelope came in the mail from the only college I had ever imagined attending. I tore open the packet. My eyes were fixed on the word “congratulations”. I don’t remember ever smiling so wide.

Then I looked at my financial(财政的)package.

The cost of Dream School’s tuition(学费), room and board was around $ 40,000--- an impossible sum! How could I afford to attend? What good reasons did I have to go there when three other fine colleges were offering me free tuition? My other choices were good, solid schools even if they weren’t as famous as my first choice.

In my mind, attending my dream university would be the only way to realize my dream of becoming a world-class writer. My parents understood how I felt. They told me that even though it would be a financial problem, I could go wherever I would be happiest. But as I was always careful with money, I wasn’t sure what to do.

One of the schools that offered me a full ride had an informational dinner one night in the spring. Considering my parents’ financial difficulties, I decided to drive the 45 minutes and attend. At first, all I had planned to do was smile politely, eat free food, listen quietly. But I surprised myself.

At dinner the president of the university talked about the wonderful activities on campus (校园)including guest lectures and social gatherings. He also made it perfectly clear that free food would be offered at all future events. He continued with explanations of professors, class sizes, activities, and sporting events on campus. As he spoke, I began to realize that this school, though not as good as my first choice, might be the best one for me. It seemed small yet with many great programs. It seemed challenging yet caring.

As the president ended his speech, we clapped politely and pushed back our chairs. As I walked out that door, a feeling of comfort washed over me. Looking at the campus that night, I realized that I would be spending the next four years right there.

In all honesty, my university is not as well-kno wn as my “dream”university. However, it turned out to be the right choice of schools for me.

4.How did the author feel when he started to read the letter?

A.He was uncertain which school to go to. B.He was lost in his dream.

C.He was worried about the money. D.He was full of joy.

5.We can learn from the passage that the parents were _________.

6.In Paragraph 5, “offered me a full ride”can be replaced by “_______”.

A.would pay for transport to the school

B.would show me around the campus

C.would offer free meals at all events

D.would charge me nothing for tuition

7.What does the author mainly want to say?

A.You should consider comfort in your choice of schools.

B.Your second-choice college may actually by your best fit.

C.You should try your best to attend your dream school.

D.Your choice of schools should be based on their fame.

Before a new type of airplane goes into service, every part of it is tested again and again. But there are two tests that are more important than all the others.

The first is called the “tank test”. A modern airplane must fly very high in the sky. Air mus t be pumped into the plane so that the passengers can breathe. The metal structure (结构) of the plane has to be very strong for this reason. When the plane is filled with air, the air presses against the skin of the plane inside. The pressure (压力) on a small window is like a huge foot that is trying to get out. If a small part of the plane were to fail, the plane would explode in the sky. To test the structure of the plane, the plane is lowered into a huge tank or container of water. Then it is filled with air. The pressure inside the plane is greater than it ever will be when it is high up in the air. Finally, there is an explosion. This does not cause so much damage inside the water tank as it would anywhere else. Engineers can discover which part of the plane has broken. Then that part is made stronger,

The most dangerous test happens when the new plane is going through test flights in the air. The test pilot must find out exactly what happens when the engines (发动机) are all shut off at once. The plane be gins to fall like a stone. It is the pilot’s job to find out how he can get control of the plane again. These two tests are examples of how planes are made safe before they ever carry passengers.

8.By doing the “tank test”, the engineers can find out ________.

A.the power of the airplane engines B.the amount of air in the plane

C.the strength of the plane structure D.the pressure inside and outside the plane 9.What will happen to the plane under the “tank test”?

A.It will be tested by pilots. B.It will be broken.

C.It will be made stronger. D.It will be filled with water. 10.According to the text. why are test flights most dangerous?

A.Too much air may get into the plane. B.The plane may explode in the air. C.The pilot may lose control of the plane. D.The engines may be damaged. 11.What might be the most suitable title for the text?

A.How Airplanes Are Made and Tested B.Two Important Tests on Airplanes C.The Importance of Flying Safely D.The Danger of Testing Airplanes

She took up skating at age 85, made her first movie appearance at age 114, and held a concert in the neighborhood on her 121st birthday.

When it comes to long life, Jeanne Calment is the world’s recordholder. She lived to the ripe old age of 122. So is 122 the upper limit to the human life span(寿命)? If scientists come up with some sort of pill or diet that would slow aging, could we possibly make it to 150-or beyond?

Researchers don’t entirely agree on the answers. “Calment lived to 122, so it wouldn’t surprise me if someone alive today reaches 130 or 135, ”says Jerry Shay at the University of Texas.

Steve Austad at the University of Texas agrees. “People can live much longer than we think, ”he says. “Experts used to say that humans couldn’t live past 110. When Calment blew past that age, they raised the number to 120. So why can’t we go higher? ”

The trouble with guessing how old people can live to be is that it’s all just guessing. “Anyone can make up a number, ”says Rich Miller at the University of Michigan. “Usually the scientist who picks the highest number gets his name in Time magazine. ”

Won’t new anti-aging techniques keep us alive for centuries? Any cure, says Miller, for aging would probably keep most of us kicking until about 120. Researchers are working on treatments that lengthen the life span of mice by 50 percent at most. So, if the average

human life span is about 80 years, says Miller, “adding another 50 percent would get you to 120. ”

So what can we conclude from this little disagreement among the researchers? That life span is flexible(有弹性的), but there is a limit, says George Martin of the University of Washington. “We can get flies to live 50 percent longer, ”he says. “But a fly’s never going to live 150 years. ”Of course, if you beca me a new species (物种), one that ages at a slower speed, that would be a different story, he adds.

Does Martin really believe that humans could evolve (进化)their way to longer life? “It’s pretty cool to think about, ”he says with a smile.

12.What does the story of Jeanne Calment prove to us?

A.People can live to 122.

B.Old people are creative.

C.Women are sporty at 85.

D.Women live longer than men.

13.According to Steve Austad at the University of Texas, ______.

A.the average human life span could be 110

B.scientists cannot find ways to slow aging

C.few people can expect to live to over 150

D.researchers are not sure how long people can live

14.Who would agree that a scientist will become famous if he makes the wildest guess at longevity?

A.Jerry Shay. B.Steve Austad

C.Rich Miller D.George Martin

15.What can we infer from the last three paragraphs?

A.Most of us could be good at sports even at 120.

B.The average human life span cannot be doubled

C.Scientists believe mice are aging at a slower speed than before.

D.New techniques could be used to change flies into a new species

二、七选五

All living things in the ocean are endangered by humans polluting the water. 16.One way is the dumping( 倾倒) of certain waste materials, such as garbage and used water,

into the ocean. The harmful bacteria that feed on the garbage use up much of the oxygen in the surrounding water, so other creatures in the area often don’t get enough.

Other substances( 物质), such as radioactive waste material, can also cause pollution. 17.But after years of being exposed to the ocean water, the containers may begin to leak(漏).

18.Oil is spilled into the ocean when oil ships sink or when oil wells in the ocean cannot be capped. The oil covers the gills( 腮) of fish and prevents them from breathing. Diving birds get the oil on their wings and are unable to fly. When they clean themselves, they are often poisoned by the oil.

Rivers also can contribute to the pollution of oceans. 19.Fertilizers used on the farmlands may be carried to the ocean, where they cause a great increase in the amount of certain plants. Too much of some plants can actually be poisonous to fish.

Worse yet are the pesticides(杀虫剂) carried to the ocean. these chemicals slowly build up in fish and other small animals. 20.The buildup of these chemicals in the animals can make them ill or cause their babies to be born dead or sick.

A.Fish and turtles suffer the most

B.Pollution occurs in several ways.

C.Oil is another major source of concern

D.Many rivers receive the runoff water from farmlands

E.Farmers use these artificial fertilizers to increase crop harvest.

F.These materials are often placed in the water in safely sealed containers.

G.These animals then pass the pesticides on to the larger animals that feed on them.

D. a harder way更困难的方法。上文家政老师给出了一个方法,Bob自己找到的方法与上文方法相比,只要关上门,不让人看到,当然比铺床,要更简单,选项A切题,故选A。37.考查动词词义辨析。句意:当我们接Pat下班回家的时候,我让孩子们穿上衣服的正面,这样衣服就显得很干净。A. receive接收;B. fetch拿来,接回(来);C. greet问候;D. welcome 欢迎。Pat在上班,所以Bob是去接在工作的Pat,选项B切题,故选B。

38.考查形容词词义辨析。句意:当我们接Pat下班回家的时候,我让孩子们穿上衣服的正面,这样衣服就显得很干净。A. good好的,优秀的;B. wrong错的;C. right正确的;D. opposite 相反的,相对的。Bob做家务是精疲力尽,上文他想出的很多办法,不做事,还能让家里看起来干净的办法如关门,为了使孩子们显得干净,也应该是想点办法,只在Pat回家才叫孩子们穿衣服的正面,符合情节发展,选项C切题,故选C。

39.考查动词词义辨析。句意:现在,Bob已经公开承认自己错了,他正在和Pat共同抚养孩子,分担家务。A. admitted承认;B. suggested建议; C. agreed同意;D. explained解释。下文Bob抚养孩子,分担家务,他以前什么都不干,不对,所以是承认不对,选项A 切题,故选A。

40.考查动词词义辨析。句意:现在,Bob已经公开承认自己错了,他正在和Pat共同抚养孩子。分担家务。A. operating操作,工作,手术;B. realizing意识到,理解;C. sharing共享,分享;D. performing演出,执行,履行。Pat原来就是做家务的,上文Bob承认错了,也要做家务,所以是两人共同,分担家务,选项C切题,故选C。

41.a

42.to climb

43.are awarded

44.peaks

45.were bathing

46.When

47.Having swallowed

48.It

49.for

50.lasting

【分析】

这是一篇说明文。介绍了我国著名的湖泊——天池。这座“天堂之湖”不仅有美丽的风景,还有迷人的神话传说。

41.考查冠词。设空词修饰名词lake,lake为可数名词,主语是三单,主表一致,lake应为单数,冠词后单词deep的首字母为辅音音素,用不定冠词a,故填a。

42.考查非谓语动词。It为形式主语,非谓语动词作主语,It takes…(时间)to do sth.固定用法,故填to climb。

43.考查被动语态。在主句中主语为you,“你”爬到山顶,看到了美景,所以是“你”被美景奖励,用被动语态,主语you,故填are awarded。

44.考查名词复数。peak为可数名词,前面的数词sixteen,提示要用其复数,故填peaks。45.考查时态。文章介绍曾经有的神话传说,故事发生在过去,当时they正在做的动作,要用过去进行时,主语复数,故填were bathing。

46.考查状语从句的连词。逗号后为主句,所以设空词所在句子为从句,根据其与主句的逻辑关系,是表示时间,从句中的动词pick up 和smell是瞬间动词,故填When。

47.考查非谓语动词。逗号后句子为两个并列句,主系表,主谓宾齐全,所以前面应用非谓语动词,非谓语动词的逻辑主语是非谓语动词的执行者,用现在分词,非谓语动词动作发生时间,在句子动词became和gave发生之前,所以要用现在分词的完成时,句首,大写首字母,故填Having swallowed。

48.考查代词。句中真正的主语为that引导的主语从句,设空词为形式主语,只有代词it

可做形式主语,句首,首字母大写,故填It。

49.考查介词。a gift for:……方面的天资(赋),固定用法,故填for。

50.考查形容词。and连接的两个部分要平行,and前为deep,形容词原级,and后也要用形容词原级,your love指物,形容物,故填lasting。

【点睛】

语法填空题中要注意非谓语动词的时态是要注意的知识点,在本题的第7小题中,先要判断非谓语动词的使用条件,因为句子为并列句,并列句的主谓宾和主系表都有,所以要填词符合使用非谓语动词的条件。然后要判断非谓语动词的种类,非谓语动词的逻辑主语为the girl,

是非谓语动词的动作的执行者,所以排除过去分词,句中非谓语动词作状语,不是表示目的和结果,排除不定式。在选定使用现在分词形式后,还要注意现在分词的时态,非谓语动词的动作发生时间,在句子动词became和gave发生之前,所以要用现在分词的完成时。

51.

【分析】

这是一篇记叙文。作者喜欢收集明信片,喜欢集剪报,因为他想成为一名记者。

【详解】

第一处:考查时态。一般过去时,主语为I,第一人称单数,故将were改为was。

第二处:考查时态。主句为一般过去时,寄名信片的人要先写、寄出来,作者才可能看到,所以从句中“写”的动作发生在主句动作之前,所以要用过去完成时,故将have改为had。第三处:考查固定短语。be addicted to中to为介词,后跟动名词,故将collect改为collecting。第四处:考查形容词。newspaper为名词,形容词修饰名词,周报:weekly newspaper,故将week改为weekly。

第五处:考查形容词。定语从句的先行词为articles,指物,关系代词在从句中作主语,指代articles,所以定语从句中的形容词要用ing形式的形容词,故将interested改为interesting。第六处:考查代词。上句中articles为复数,作者stick的是这些剪下来的文章,所以代词指代的是剪下来的文章,代词要用复数,指物,故将it改为them。

第七处:考查介词。of表示归属的介词,句中shelf与whole不是归属关系,whole是形容词修饰后面的名词,故将of去掉。

第八处:考查疑问代词。下句回答的句子中用的是连词是because,所以前面的问句是问原因,疑问代词要用why,故将How改为Why。

第九处:考查冠词。journalist为可数名词,主语I,主表要一致,所以表语要用单数,单词首字母为辅音音素,故加上a。

第十处:考查名词复数。journalists为复数,其所有格修饰后面的名词,writing为可数名词,

名词要与所有格一致,名词要用复数,故将writing改为writings。

52.Dear Mr. Headmaster,

I am Li Hua , a student from class one ,senior two . I am writing to draw your attention to some improper behavior among us students : littering and scribbling . It makes our school dirty and unpleasant , and does harm to the image of our school . I always feel ashamed whenever I see this . It is clearly not appropriate for a student to litter and scribble about. I wonder if the school could place more dustbins around and set up specific rules against such behavior. At the same time , students should be encouraged to develop good habits and better behave themselves. I believe that , with the joint efforts of both teachers and students ,our school will become a more enjoyable place in the near future. Thank you for your consideration.

Yours

02 q E k R = a 、b 带正电,故a 在O 点产生的场强方向是由a 指向O ,b 在O 点产生的场强方向是由 b 指向O ,由矢量合成得a 、b 在O 点产生的场强大小 2q E k R = 方向由O →c ,选项C 错误; D .同理c 在O 点产生的场强大小为 02q E k R = 方向由O →c 运用矢量合成法则得a 、b 、c 在O 点产生的场强 22q E k R '= 方向O →c 。选项D 正确。 故选BD 。 2.电荷量相等的两点电荷在空间形成的电场有对称美.如图所示,真空中固定两个等量异种点电荷A 、B ,AB 连线中点为O.在A 、B 所形成的电场中,以O 点为圆心半径为R 的圆面垂直AB 连线,以O 为几何中心的边长为2R 的正方形平面垂直圆面且与AB 连线共面,两个平面边线交点分别为e 、f ,则下列说法正确的是( ) A .在a 、b 、c 、d 、e 、f 六点中找不到任何两个场强和电势均相同的点 B .将一电荷由e 点沿圆弧egf 移到f 点电场力始终不做功 C .将一电荷由a 点移到圆面内任意一点时电势能的变化量相同 D .沿线段eOf 移动的电荷,它所受的电场力先减小后增大 【答案】BC 【解析】 图中圆面是一个等势面,e 、f 的电势相等,根据电场线分布的对称性可知e 、f 的场强相同,故A 错误.图中圆弧egf 是一条等势线,其上任意两点的电势差都为零,根据公式W=qU 可知:将一正电荷由e 点沿圆弧egf 移到f 点电场力不做功,故B 正确.a 点与圆面内任意一点时的电势差相等,根据公式W=qU 可知:将一电荷由a 点移到圆面内任意一点时,电场力做功相同,则电势能的变化量相同.故C 正确.沿线段eof 移动的电荷,电场强度 先增大后减小,则电场力先增大后减小,故D 错误.故选BC . 【点睛】等量异种电荷连线的垂直面是一个等势面,其电场线分布具有对称性.电荷在同

吉林省舒兰市第一中学高中语文 题乌江亭项素材话题素材 新人教版必修1

当虞姬横刀,将一朵生命之情绽放成矛尖锋刃的湛蓝。我看到鲜红鲜红的血流过雪白雪白的颈。壮士掩面,乌骓悲鸣。 鲁迅说成功是把好的东西包装给人看,而失败是把好的东西毁灭给人看。于是,你便成了最伟大的毁灭的艺术。“曾是气吞残虏!”你的英勇是无人企及的神话。釜破舟沉,是你无畏的誓言。“何弊之乘”的果敢,“挡我者死”的豪迈。几千年后似乎还可以听到你圆睁环眼倒竖钢髯的一声断喝。乌骓马来往奔突,每一个轮回的拼杀都像是一条法力无边的咒语,使尸堆成山,使血流成河。那杆长予挑起了几多秦国虎狼之将的尸首,几千年后壁上清吟之时还自滴着秦兵的黑血! 然而,你胜不了刘邦。因为你,还有诚信。 “竖子不足与谋!”范增如是说。当楚强汉弱之时,诛刘邦之机会何止千万。然而你没有。“不可沽名学霸王。”毛泽东说你沽名钓誉,我没有看到,我只看到你的诚信。“此沛公左司马曹无伤言之。”你直言不讳,面对的还是刘邦。于是曹无伤被诛,试问天下谁人再敢助楚?你以为楚河汉界便是界限,殊不知刘邦有心明修栈道,暗渡(度)陈仓!韩信谓刘邦不善用兵而善用将,他的心计,他的丢诚弃信便是他的武器。而这居然比你的宝马大刀还要锋利。然而刘邦不足以与你相比;刘邦是君主,而项羽,是英雄!于是你英雄的起事,英雄的南征北战,英雄的失败。当楚歌的韵律从四面八方像魔音一般折磨你的耳鼓,面对嘶鸣的乌骓和似水的虞姬,你的眼泪磨蚀你的伟岸。“虞姬虞姬奈若何?”于是在乌江,你完成了一个没有丢弃诚信的男人的毁灭艺术。 当拔山举鼎的传奇褪色成一页泛黄的史册,与斜阳下汉家的小儿稚嫩的传唱“大风起兮云飞扬”,你终于远去,留下一个顶天立地的背影。也许你做了鬼雄,跨着随你投江而死的乌骓,旌旗十万斩阎罗,你轰轰烈烈的死去,因为有诚信,为你殉葬。 于是,你不朽,你最终还是战胜了刘邦,以你的诚信,刺刘邦于后人的口碑之下! 【简评】 仅仅用“中心明确,语言优美”来评价这篇散文,是远远不够的。这位考生不以成败论英雄,而是以“诚信”为中心,深入探究人性的善恶美丑,阐述了独到而深刻的见解。这种不拘前人旧说,用充满思辩色彩的严密推理得出的结论,表现了一种十分可贵的科学的创新精神。再加上严谨无隙而又流动自如的结构,优美畅达而又灵动轻捷的语言,便将这种深邃的哲理思考悄无声息地融进了充分诗化的语言和无处不在的情感氛围之中,显示了作者相当成熟而扎实的语文素养。 【素材运用】 1、话题"意气": 在棋盘拼杀,楚河汉界分明,我会一如既往想起楚王项羽与汉王刘邦。虞姬的自刎,乌骓的投江让更多的人倒向项羽,鸿门宴上的刘邦似乎只是小人,听听汉家小儿高唱"大风起兮云飞扬"便热血沸腾,可历史的车轮证明了刘邦比项羽更能成就一番大业。是他主张张骞扶着驼铃走向了大漠,是他让卫青挥动旌旗舞向了大漠的飞沙。他们都是英雄,皆有意气,是意气二字所有义项不同,楚王的意气用事,与汉王的意气风发。王安石《题乌江亭》:百战疲劳壮士哀,中原一败势难回。江东弟子今犹在,肯为君王卷土来?(湖南高考满分作文《谈意气》) 2、话题"自信": 项羽过于相信自己。大家都知道项羽破釜沉舟的故事,他在战场上一向是攻无不克,战无不胜。别的暂且不说,只那以少胜多的钜鹿之战就令人惊叹不已。恐怕正因如此,项羽养成了孤傲的性格。无论什么都以己为尊,好像这天下除了他就再也没有别的人可以收拾了。独断专行使历史陷入了沉思,过分的自信也就铸下了这千年的遗憾。(安徽高考满分作文《刚愎自用的典型--项羽人物形象刍议》) 3、话题"相信自己与听取别人的意见": 乌江岸边,夜色如水。如漆的夜里张扬着狰狞,一支支闪烁的火把如一支支泛着幽蓝的眼睛。啊--是谁用凄凉的声音,在唱一首首熟悉的楚歌?是三千江东子弟不散的英灵吗?骓,僵卧在它曾经踏起飞尘的黄沙中,一朵冷艳开在虞姬如雪的粉颈上。呐喊依旧。如霜的冷刃上浸染着殷红的温暖,一具勇猛硕大的躯体缓缓躺在孕育它的大地上。在这个不灭的神话中,留下了千年的遗憾。亚父范增的一句"竖子不足与谋"似乎就已奠定了悲剧的基础。鸿门宴,亚父频举的玉玦,不在你的双眼,项庄、项伯的舞剑成了千古的笑资。在你自负的笑声中,溜走了你的宿敌。我是谁?我是叱咤风云的西楚霸王。他,刘邦小儿算得什么?他有破釜沉舟、九战九捷的自信与魄力吗?什么智勇双全的韩信求见,哼,一个胯下之父来到这里谋职,让他滚!我这里不缺谋士!一辆破旧的马车,蹒跚前行,浑浊的老泪在范增满是沟壑的脸上纵横……一切都完了,为什么到临死的时候,你还怀着"时不利兮"的愤怒,冲不破自负的牢笼呢?(满分作文《千年的遗憾》) 4、话题"自己的认知和他人的期望":
