The journey my daughter Cathy has had with her swimming is as long as it is beautiful.
Cathy suffered some terrible 16 in her early childhood. After years of regular treatment, she 17 became healthy.
Two years ago, while Cathy was watching the Olympics, a dream came into her sweet little head—to be a swimmer. Last summer, she wanted to 18 out local swim team. She practiced hard and finally 19 it. The team practice, 20 was a rough start. She coughed and choked and could hardly 21 her first few weeks. Hearing her coughing bitterly one night, I decided to 22 her from it all. But Cathy woke me up early next morning, wearing her swimsuit 23 to go! I told her she shouldn’t swim after a whole night’s coughing, but she refused to 24 and insisted she go .
From that day on, Cathy kept swimming and didn’t 25 a single practice. She had a 26 intention within herself to be the best she could be. My ten—year—old was growing and changing right before my eyes, into this 27 human being with a passion and a mission. There were moments of 28 of course: often she would be the last swimmer in the race. It was difficult for Cathy to accept that she wasn’t a 29 ---ever. But that didn’t stop her from trying.
Then came the final awards ceremony at the end of the year. Cathy didn’t expect any award but was still there to 30 her friends and praise their accomplishments.

Every man wants his son to be somewhat of a clone, not in features but in footsteps. As he grows you also age, and your ambitions become more unachievable. You begin to realize that your boy, in your footsteps, could probably accomplish what you hoped for. But footsteps can be muddied and they can go off in different directions.
My son Jody has hated school since day one in kindergarten. Science projects waited until the last moment. Book reports weren’t written until the final threat.
I’ve been a newspaperman all my adult life. My daughter is a university graduate working toward her master’s degree in English. But Jody? When he entered the tenth grade he became a “vo-tech” student(技校学生). They’re called “motorheads” by the rest of the student body.
When a secretary in my office first called him “motorhead”, I was shocked. “Hey, he’s a good kid,” I wanted to say. “And smart, really.”
I learned later that motorheads are, indeed, different. They usually have dirty hands and wear dirty work clothes. And they don’t often make school honor rolls(光荣榜).
But being the parent of a motorhead is itself an experience in education. We who labor in clean shirts in offices don’t have the abilities that motorheads have. I began to learn this when I had my car crashed. The cost to repair it was estimated at $800. “Hey, I can fix it,” said Jody. I doubted it , but let him go ahead, for I had nothing to lose.
My son ,with other motorheads, fixed the car. They got parts(零件)from a junkyard, non-toasting toaster have been fixed. Neighbours and co-workers trust their car repair to him.
Since that first repair job, a broken air-conditioner, a non-functioning washer and a non-toasting toaster have been fixed. Neighbors and co-workers trust their car repairs to him.
These kids are happiest when doing repairs. They joke and laugh and are living in their own relaxed world. And their minds are bright despite their dirty hands and clothes.
I have learned a lot from my motorhead: publishers need printers, engineers need mechanics, and architects need builders. Most important, I have learned that fathers don’t need clones in footsteps or anywhere else.
My son may never make the school honor roll. But he made mine.
41. What used to be the author’s hope for his son?
A. To avoid becoming his clone.
B. To resemble him in appearance.
C. To develop in a different direction.
D. To reach the author’s unachieved goals.
42. What can we learn about the author’s children?
A. His daughter does better in school.
B. His daughter has got a master’s degree.
C. His son tried hard to finish homework.
D. His son couldn’t write his book reports.
43. The author let his son repair the car because he believed that_______.
A. His son had the ability to fix it.
B. it would save him much time.
C. it wouldn’t cause him any more loss
D. other motorheads would come to help.
44. In the author’s eyes, motorheads are _______.
A. tidy and hardworking
B. cheerful and smart
C. lazy but bright
D. relaxed but rude
45. What did the author realize in the end?
A. It is unwise to expect your child to follow your path.
B. It is important for one to make the honor roll.
C. Architects play a more important role than builders.
D. Motorheads have greater ability than office workers.
C
When John was growing up, other kids felt sorry for him. His parents always had him weeding the garden, carrying out the garbage and delivering newspapers. But when John reached adulthood, he was better off than his childhood playmates. He had more job satisfaction, a better marriage and was healthier. Most of all, he was happier. Far happier.
These are the findings of a 40-year study that followed the lives of 456 teenage boys from Boston. The study showed that those who had worked as boys enjoyed happier and more productive lives than those who had not. “Boys who worked in the home or community gained competence (能力) and came to feel they were worthwhile members of society,” said George Vaillant, the psychologist (心理学家) who made the discovery. “And because they felt good about themselves, others felt good about them.”
Vaillant’s study followed these males in great detail. Interviews were repeated at ages 25, 31 and 47. Under Vaillant, the researchers compared the men’s mental-health scores with their boyhood-activity scores with their boyhood-activity scores. Points were awarded for part-time jobs, housework, effort in school, and ability to deal with problems.
The link between what the men had done as boys and how they turned out as adults was surprisingly sharp. Those who had done the most boyhood activities were twice as likely to have warm relations with a wide variety of people, five times as likely to be well paid and 16 times less likely to have been unemployed. The researchers also found that IQ and family social and economic class made no real difference in how the boys turned out. Working----at any age----is important. Childhood activities help a child develop responsibility, independence, confidence and competence---the underpinnings (基础) of emotional health. They also help him understand that people must cooperate and work toward common goals. The most competent adults are those who know how to do this. Yet work isn’t everything. As Tolstoy once said, “One can live magnificently in this world if one knows how to work and how to love, to work for the person one loves and to love one’s work.”
46. What do we know about John?
A. He enjoyed his career and marriage.
B. He had few childhood playmates.
C. He received little love from his family.
D. He was envied by others in his childhood.
47. Vaillant’s words in Paragraph 2 serve as _____.
A. a description of personal values and social values
B. an analysis of how work was related to competence
C. an example for parents’ expectations of their children
D. an explanation why some boys grew into happy men
48. Vaillant’s team obtained their findings by _____.
A. recording the boys’ effort in school
B. evaluating the men’s mental health
C. comparing different sets of scores
D. measuring the men’s problem solving ability
49. What does the underlined word “sharp” probably mean in Paragraph 4?
A. Quick to react
B. Having a thin edge
C. Clear and definite
D. sudden and rapid
50. What can be inferred from the last paragraph?
A. competent adults know more about love than work.
B. Emotional health is essential to a wonderful adult life.
C. Love brings more joy to people than work does.
D. Independence is the key to one’s success.
D
Failure is probably the most exhausting experience a person ever has. There is nothing more tiring than not succeeding.
We experience this tiredness in two ways: as start-up fatigue(疲惫) and performance fatigue. In the former case, we keep putting off a task because it has either too boring or too difficult. And the longer we delay it, the more tired we feel.
Such start-up fatigue is very real, even if not actually physical, not something in our muscles and bones. The solution is obvious though perhaps not easy to apply: always handle the most difficult job first.
Years ago, I was asked to write 102 essays on the great ideas of some famous authors. Applying my own rule, I determined to write them in alphabetical(按字母顺序), never letting myself leave out a tough idea. And I always started the day’s work with the difficult task of essay-writing. Experience proved that the rule works.
Performance fatigue is more difficult to handle. Though willing to get started, we cannot seem to do the job right. Its difficulties appear so great that, however hard we work, we fail again and again. In such a situation, I work as hard as I can-then let the unconscious take over.
When planning Encyclopaedia Britannica (《大英百科全书》), I had to create a table of contents based on the topics of its articles. Nothing like this had ever been done before, and day after dat I kept coming up with solutions, but none of them worked. My fatigue became almost unbearable.
One day, mentally exhausted, I wrote down all the reasons why this problem could not be solved. I tried to convince myself that the trouble was with the problem itself, not with me. Relived, I sat back in an easy chair and fell asleep.
An hour later, I woke up suddenly with the solution clearly in mind. In the weeks that followed, the solution which had come up in my unconscious mind provided correct at every step. Though I worked as hard as before, I felt no fatigue. Success was now as exciting as failure had been depressing.
Human beings, I believe must try to succeed. Success, then, means never feeling tired.
51. People with start-up fatigue are most likely to .
A. delay tasks
B. work hard
C. seek help
D. accept failure
52. What does the author recommend doing to prevent start-up fatigue?
A. Writing essays in strict order.
B. Building up physical strength.
C. Leaving out the toughest ideas.
D. Dealing with the hardest task first.
53. On what occasion does a person probably suffer from performance fatigue?
A. Before starting a difficult task.
B. When all the solutions fail.
C. If the job is rather boring.
D. After finding a way out.
54. According to the author, the unconscious mind may help us .
A. ignore mental problems
B. get some nice sleep
C. gain complete relief
D. find the right solution
55. What could be the best title for the passage?
A. Success Is Built upon Failure
B. How to Handle Performance Fatigue
C. Getting over Fatigue: A Way to Success
D. Fatigue: An Early Sign of Health Problems

I’m a 34-year-old man, married, lived in a nice house, and have a successful career as an educational consultant. But my life was not always so great. I had a learning disability from an early age. I went to a special school where I got plenty of extra help. Still, I suffered the rest of my school days in public schools.
My life improved remarkably when I discovered art. The art world gave me a chance to express myself without words. I went to a workshop and gradually got good at making things with clay(黏土). Here I learned my first important lesson: disabled as I was in language. I could still be smart and well express myself with clay. And my confidence came along.
I got my next lesson from rock climbing. It was a fun thing but I was scared from the start. I soon noticed it wasn’t a talent thing; it was practice. So I did it more. After about five years of climbing, I found myself in Yosemite Valley on a big wall. I learned that if you fall in love with something and do it all the time, you will get better at it.
Later I decided to apply my previous experience to learning how to read and write. Every day I practiced reading and writing, which I used to avoid as much as possible. After two hard years, I was literate.
Having gone through the long process with art, rock climbing, and reading and writing, now I’ve got to a point in my life where I know I am smart enough to dive into an area that is totally unknown, hard, but interesting.

2016年贵州高考作文立意(精选15篇)篇2
2016年辽宁高考文科状元是两人 竟然是同班同学
2016年辽宁高考文科状元是:周子祺和党英伦,两人都是637分
这两位学霸来自同一所高中同一个班——大连育明高中三十班
让我们一起来分享一下他们的故事吧。
周子祺,来自丹东,毕业于大连育明高中,目标是清华或北大,她的兴趣爱好是音乐,平时会用音乐来放松,她还会弹柳琴和中阮。
成功的原因有很多,其中高中三年住宿让她可以更投入学习
在这之前几次模拟考试成绩不是很好,所以这次高考的成绩对她来说是一个很大的惊喜
她很感谢班主任王丽老师对她的鼓励,按照自己的复习节奏坚持下去,坚持自己的梦想。
周子祺说,她喜欢财经方面的专业,想去清华北大。
周子祺一个阳光女孩,还获得了2014-2015年度大连市三好学生
她和同学关系都特别好,乐于助人,是一个乐观的人。
她还是班里的生活委员,常常管一些杂七杂八的事儿,但她都很开心。
她总结了成功的很多原因,其中一个是住校对学习有促进作用,因为在学校上晚自习,回寝室和同学一起学习,探讨问题、互相讲解,对学习促进很大。
在妈妈心中,周子祺是一个目标鉴定的女儿。
妈妈也一直对女儿的学校很关注,每一次考试成绩公布后,她们娘俩都会坐下来,一科一科分析。哪一科分高一些?哪一科分低一些?存在什么问题?从小学到高中,无论期中考试还是期末考试,她们都是这样做的
谈及学习经验,周子琪分享了3个重点:
一是紧跟老师节奏走,上课认真听讲,课下按时完成作业
二是刨根问底,遇到问题及时和老师沟通
三是积累,平时注意作文素材积累、好词好句积累
党英伦,来自营口,毕业于大连育明高中,平时乐于参加学校各种活动,最爱看电影,喜欢电子竞技游戏。虽然还没想好去哪所大学,但他已经选定了法律专业
对他来说这次能成为大连的文科状元是他意料之外的事情,他平时他的成绩是前三
他也分享了学习的经验:
第一点是学习跟上学校的步伐,因为育明高中的的节奏很快、教学质量很高,如果能跟上学校的步伐,一定没有问题。
第二点是始终保持信心,保持积极向上的心态。不要因为平时考的不好而影响心情,要保持平常心。这次高考他也没有做特别的准备,就是当成一次平常的考试去考,然后取得了一个让人称赞的分数。
和周子琪不同的是他高中没有住校,而是一直在学校附近租房子。因为有亲戚照顾,租房子可以使学习时间更长一些。
党英伦是一个性格开朗的男孩,性格比较随和,他没有将所有时间都投入到学习上,而是参加学校活动或者休闲
对于那些即将进入高三的学弟,党英伦给出自己的建议:
1、始终跟着学校,节奏要对
2、不要太疲劳,学习时间把握在一定程度内,学会儿,休息会儿,要做到张弛有度。
2016年贵州高考作文立意(精选15篇)篇3
现在,兰州大街小巷到处都是房地产广告,公交车站站牌、出租车顶灯、电视上、广播里。
以前,我对于这些房地产广告是没有感觉的,就算是城市中各个角落都充斥着房地产广告的气息,与我也没有任何联系;自爸爸买了房子之后,这一切都变了。
我开始对房地产广告产生厌恶的情绪,开始痛恨兰州的高房价,开始抵触、拒绝任何房地产消息,比如广播里给某某楼盘打广告时,会毫不犹豫换台。
人们常说一年有四季,而我的人生仿佛只有两季:春季和冬季,两个季节的时间分界点就是爸爸买房子。
作为家里的独生女,爸爸给予我无尽的爱,能满足任何我的需求,当然这是在没有房子之前。
小时候,去邻居家玩耍,看到小朋友的芭比娃娃,非常喜欢,感觉比电视里面的还要漂亮。回家之后央求爸爸给我买一个,第二天,爸爸就带我去商场,买了最贵的芭比娃娃给我,满足我的少女心。
十八岁的女生,逐渐开始追求外表的美丽,我也不例外。周末,和同学一起去逛商场,一条漂亮的裙子吸引了我的注意力,但是摸摸兜里的钱,只能掉头回家;回家之后我向爸爸表现出我对于那条裙子的喜爱,但是久久没有得到爸爸的回应。
我知道家里正在还房贷,非常缺钱,我也理解爸爸默不作声的行为,但是愿望得不到满足,心里还是会有一丝丝失落。
我真切感受到兰州的高房价,几十万的房贷就像是一座大山一样,死死压在爸爸的肩上,丝毫不给他喘息的机会。
以前,爸爸都是抽十八块钱的黑兰州,买房之后爸爸选择十块钱的红塔山;以前,爸爸吃牛肉面都是加肉加蛋,买房之后爸爸只要一碗牛肉面,偶尔吃不饱会加一个大饼。
这些生活中的小细节,恰如其分的说明高房价对于爸爸的改变,或者说爸爸是被改变,迫于房贷的压力。
常常听大人们聊天:兰州是个低收入高消费的城市、兰州的房价在西北五省居首位、兰州房价又涨了……
时至如今,我仍然不能理解,兰州新建了许许多多的房子,而且很多都卖不掉,为什么房价不降反增,还是这么高?
假如房子每平米便宜一百元,按我们家一百平米大小的房子算,就可以便宜一万元。而这一万元,爸爸不用在香烟上省钱了,吃牛肉面可以加肉加蛋了,而我的裙子也有了着落。
当我们说“假如”的时候,这件事就不可能发生,只能是臆想一下;回归到现实,爸爸还要牺牲很多去还房贷,为高昂的房价付费;而我,也将成房贷的牺牲品,要放弃很多喜欢的裙子、衣服。
当房贷剥夺我喜欢的东西时,当高房价逼得爸爸在生活中处处节约时,恨意自心中油然而生,无法抑制。
每当放学在车站等公交车时,看到房地产广告牌,想到爸爸省钱还房贷,心里的怒火就像火山岩浆一样要喷发出来,在车站人比较少的时候,过去踹两脚广告牌,发泄一下对于兰州高房价的恨意。
有时候,想站在最高处大喊一声:兰州的高房价,我恨你!

郎平:雄心志四海
【颁奖词】临危不乱,一锤定音,那是荡气回肠的一战!拦击困难、挫折和病痛,把拼博精神如钉子般砸进人生。一回回倒地,一次次跃起,一记记扣杀,点染几代青春,唤醒大国梦想。因排球而生,为荣誉而战。一把铁榔头,一个大传奇!
【人物事迹】1984年洛杉矶奥运会女排决赛,中美巅峰对决,身高1米84的中国女排主攻手郎平击溃了美国女排的防线,帮助中国女排登上了冠军的宝座,赛后诞生了一个流行词——“铁榔头”。“铁榔头”郎平两次在中国女排最困难的时期,主动接下了中国女排主帅这个“星球上压力最大的职业”:第一次是1995年女排生死存亡之际,她毅然归国,担任女排主帅,累倒在工作当中;第二次是2012年中国女排伦敦奥运会被日本队淘汰,2013年同年龄队友陈招娣撒手人寰,这一系列的悲痛触动了郎平内心深处的女排情结。于是她冒着“一世英名可能毁于一旦”的风险再次走马上任,仅仅一年半时间,郎平就带领中国队于2014年时隔16年重返世锦赛决赛舞台,最终夺得亚军,并于2015年重夺世界杯冠军。30年来,从担任主攻手时的“五连冠”到任教练率中国女排重返世界之巅,“铁榔头”似乎已经是奇迹的代名词。

官东:天下英雄气
【颁奖词】来不及思量,就一跃而入,冰冷、漆黑、缺氧,那是长江之下最牵动人心的地方,别紧张,有我在,轻声的安抚,稳住倾覆的船舱,摘下生命软管,那肩膀上剩下的只有担当,人们夸你帅,不仅仅指的是面庞。
【人物事迹】2015年6月1日,“东方之星”号客轮在长江中游湖北监利水域翻沉。官东主动请缨加入海军工程大学抢险救援分队。6月2日抵达救援现场后,他第一个跳入水中,面对水流湍急、能见度极低的双重考验,官东首先在船舱内发现朱红美老人,他一边耐心安抚老人的情绪,一边帮她穿戴好装具,最终成功将其救出,这是第一位被成功救出的生还者。14时15分,官东再次下水,在机舱部位找到了船员陈书涵。面对体力严重透支,陷入绝望的陈书涵,官东毫不犹豫地将自己的装备给了陈书涵,自己冒着生命危险仅靠轻潜装具支撑。撤退时,他身上的信号绳被缠住,危急之下,官东割断信号绳,与水面彻底失联。官东在黑漆漆的舱内摸索近20分钟,终于找到出舱口,怎料,一个暗流瞬间将他卷入深水区,而此时,装具里的氧气即将耗尽,官东果断丢掉所有装具,憋着一口气猛地往上游。由于上升速度过快,刚出水的官东双眼通红、鼻孔流血。面对大家的赞许,这个帅气的90后小伙儿,没有多言。因为在他看来,这是军人应有的担当。

王宽:君子抱仁义
【颁奖词】重返舞台,放不下人间悲欢,再当爷娘,学的是前代圣贤,为救孤,你古稀高龄去卖唱,为救孤,你含辛茹苦十六年,十六年,哪一年不是三百六十天,台上,你苍凉开腔,台下,你给人间作榜样。
【人物事迹】郑州戏曲圈里有这样一位老艺术家:台上兢兢业业唱好戏,台下尽心尽力做善事,戏迷们夸他是德艺双馨的好人,他就是74岁的王宽。1998年退休后,王宽夫妇陆续收养了6名老家的孤儿。为了供养这些孩子吃饭穿衣、读书学艺,王宽决定放下自己国家一级演员的身段,去茶楼卖唱,这一唱就是7年。起初,他的“上台率”并不高,每晚冷板凳一坐就是五六个小时。
但王宽依旧坚持每天骑着自行车,一家一家茶馆地跑,常常晚上六七点就去了茶馆,等到天亮才回家。后来为了能够让更多人点他的戏,王宽又学起了川剧变脸。如今,王宽夫妇苦心抚养的几个孩子都已长大成人,自食其力,而老两口却还在坚持资助老家的孩子。他们最大的愿望就是办起一个孤儿艺校,发挥自己的特长和余热,让这些孩子学到一技之长。王宽老师用他的行动向大家传达爱的意义。

2015年1月14日下午大约一点半乐山发生了一场5级地震,原本对于“习惯”地震的四川人而言5级地震是算不得什么大事的,但是因为震中就在本市的缘故,我也被这至少超过5秒钟的较强烈震感吓了一跳。
08年汶川地震以后,几乎每一年都能听到不止一次关于四川地震的消息。但是,除了那次和13年的雅安地震以外,这次便是我感受最真切也感到最害怕的一次。因为震感强烈,所以我也会后怕,若是那一刻震级不止5级怎么办,要是真的房屋被震塌怎么办,要是被埋在废墟里了怎么办······就像没有人会知道谁的生活是否会在哪一天被拦腰斩断一样,这样的天灾确实无人预知、无法预料。就像我在这一刻虽然抱着电脑舒服地在沙发上敲下这一字一句,说不定下一刻又会感受到地震带来的震撼。
没有人比经历过地震的人更恐惧地震,因为我们切实体会过为了保命争先恐后以最快的速度从楼上跑向平地的瞬间,真切了解震后因通讯崩溃联系不上亲人不知对方是否安全的焦急,而我也曾确实在08年地震那一刻,跑下楼的时候被同学踩到脚趾出血也浑然不知。当然,震中及附近的居民遭受的就更不止这些了。
然而,这几年以来尽管四川年年有地震,但似乎全国人民都知道四川人“不怕”地震,四川网民也总是淡定的调侃“小震不用跑,大震跑不了”。同时四川人一直以来被大家熟知的“爱玩好吃”的习惯也不曾因为地震而改变,成都的休闲慢节奏生活也全国皆知,这种及时行乐享受生活的状态完全没有也不会因为可怕的地震而受到影响。因为正是在这种不可预知未来的生活中,我们更要懂得活在当下,即使没有下一刻也不会感到后悔。天府之国生活的安逸闲适,虽然并不只是因为地震后的人们更懂得珍惜现在而形成,但却会因为这一点让大家持续这种状态,享受生活,活好每一刻,不留遗憾。
生活让我们知道未来不可预知,但是最重要的是要明白,正因如此,我们更要活好当下的每一刻。每一片树叶都不知道它会在哪一刻以哪种方式脱离树枝,但这却丝毫不影响它即使是在树上的最后一刻,也向人们展现它的美好状态的生命姿态。我也不会再因为这突如其来,并且不知道未来何时还会来的地震影响我的生活,活好每一刻不留遗憾就是最棒的选择和最好的状态,这才是我该有的生命姿态。

D、站在领奖台上,刘翔对领奖台的压力与领奖台对他的支持力,作用在两个物体上,大小相等、方向相反、作用在同一直线上,这两个力是一对相互作用力,故该选项说法不正确.
故选A.
4、答案A解:A、初春冰雪消融是冰吸热由固态变成液态的熔化过程,正确;
B、夏天用电风扇对着人扇风,人感到凉爽是因为扇风加快了身体上汗液的蒸发,蒸发要吸热,从而使人体温度降低,感到凉爽,错误;

故选A
5、答案C
物体从2倍焦距外沿主光轴移向焦点的过程中,物距大于一倍焦距,所以成实像,
而移动时,物距逐渐变小,则像距逐渐变大,像逐渐变大.
故选C.
6、答案D
7、空气;1m/s.
8、①房间里充满了蚊香的气味,说明分子处于运动状态,叫扩散现象;
②电热灭蚊器在工作过程中将电能转化为内能.
故答案为:扩散;电能转化为内能.
9、700;0。07
10、解:(1)在水平地面上做匀速直线运动的木箱,受到的是平衡力的作用:竖直方向上的重力与地面对它的支持力是一对平衡力;水平方向上的推力与摩擦力是一对平衡力,因此地面对木箱的摩擦力大小为30N.
(2)若小明将推力增大到30N时,木箱对地面的压力和木箱与地面间的粗糙程度没有改变,因此木箱受到的摩擦力仍然为20N,所以木箱受到的合力大小F合=30N-20N=10N.
故答案为:20;10.
11、3000;4。5.
12、(1)甲灯泡的额定电压U甲=9V,由图象可知额定电流I甲=0。8A,
甲灯泡的额定功率P甲=U甲I甲=9V×0。8A=7。2W;
(2)当甲、乙两灯串连接入9V的电路中,则
U=U甲+U乙=9V,I=I甲=I乙,
由图象可知,当I=0。4A时符合;
通电10s两灯消耗的总电能:
W=UIt=9V×0。4A×10s=36J.
故答案为:7。2;36.
13、
14、答:(1)轿车的外形类似于飞机的机翼,轿车在快速行驶过程中,车子上方空气的流速大于车子下方空气的流速,因而车子上方气体的压强小于车子下方气体的压强,轿车上下方所受到的压力差形成向上的升力,从而使得轿车对地面的压力小于车的重力.
(2)等质量的空气在相同的时间内同时通过轿车的上表面和下表面,由于轿车上表面弯曲,下表面平直,所以空气通过轿车上表面的流速大,通过下表面的流速较小.
(3)在高速行驶中由于车身上下两面的气流压力不同,下面大上面小,这种压力差必然会产生一种上升力,车速越快压力差越大,上升力也就越大.因为当轿车时速达到一定的数值时,升力就会克服车重而将车子向上托起,减少了车轮与地面的附着力,使车子发飘,造成行驶稳定性变差.
15、解:(1)在测绳端拉力时,需竖直向上匀速拉动测力计.
答案为:匀速.
(2)答案为:74%.
(3)由数据知第2次实验中,s为h的3倍,所以滑轮组由3段绳子承担物重,而被提升的物重为6N,其它3组为4N.所以第2次实验是用b图做的;
第4次实验s为h的5倍,所以滑轮组由5段绳子承担物重,所以第4次实验是由c图做的.
故答案为:b;c.
(4)分析第1、2次实验,两次所用滑轮组相同,但第2次物重大于第1次物重,机械效率也大于第1次的机械效率,所以可得使用同一滑轮组,提高物重可以提高滑轮组的机械效率.
分析第1、3次实验,两次提升物体的重力相同,第3次实验的动滑轮较重,而机械效率较低,所以可得使用不同的滑轮组,提升相同的重物,动滑轮个数越多(即动滑轮总重越重),滑轮组的机械效率越低.
故答案为:提高物重;越低.
(5)第3、4次实验只是改变了物体被提升的高度,机械效率没变,所以可得滑轮组的机械效率与物体被提升的高度无关.
故答案为:无关.
16、(1)根据灯泡的额定电压确定电压表的量程,灯泡、滑动变阻器串连接入电路,电压表并联在灯泡两端,连线时,注意滑动变阻器的接法,注意电压表正负接线柱不要接反;
(2)为保护电路,闭合开关前,滑动变阻器接入电路的阻值应为滑动变阻器的最大阻值,根据滑动变阻器的接法判断滑片的位置;
(3)由图乙确定电流表的量程与最小分度值,根据电流表指针位置读出电流表示数,然后由P=UI求出灯泡的额定功率;
(4)开关闭合,把灯泡从插座上拔出后,电路断路,电流表无示数,电压表直接接在电源两端,测电源电压,电压表有示数,且示数等于电源电压.
17、解:
(1)∵P=1。5W,t=24h=24×3600s=86400s,
∴一昼夜(24h)心脏对血液做的功为:W=Pt=1。5W×86400s=129600J=1。296×105J.
