第一篇
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。

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.

人们常说:小合作有小成就,大合作有大成就,不合作就很难有成就。在现实生活中,我就有和别人合作的经历。
一天我们上体育课,刚好,二班也上。他们与我们不同的是,他们手里多了一条拔河的绳子。我们看见了心里痒痒的也想玩,被二班的单老师听到了,她就说:“要不你们来一场比赛吧。”我们高兴得一蹦三尺高,便拿起了绳子的另一端,比赛开始了------我们狠劲的拉着绳子,可是,我能感觉绳子左右摇晃,把我带扯的跟着跑,根本用不上劲,还有同学往我脚上踩,还有的干脆坐在地不起来了。而二班的同学就不一样了,还没开始呢,他们就拉开架势,一喊开始,有劲的同学使劲拉,没有拉的同学大喊加油------不用说,这第一回合我们败了下来。
同学们不服气,继续第二回合,单老师说:“这次我们每个班挑五个人比赛。”大家都同意,都挑了五个力量大的同学参加。一声令下,二班的还是步伐一致的拉,声音一致的喊加油。我们班还是难以招架,就有同学一边拉着,还一边埋怨同学拉的不够用劲,他就说我用劲了,你没用劲-----每个同学都认为对方不对,第二回合,失败!
同学们有的气馁了,可碍于面子这第三回合不拉不行啊,拉吧,勉强上来几个不怕死的,招呼在远处看热闹的同学,来跟前喊加油,他们坐在矮墙上耷拉着二郎腿,咬着手指笑,就是不来,就有同学骂脏话------赌气拉一回合,不等二班欢呼,拉的同学扔下手中的绳子,头也不回的大步回教室,那些刚才还笑的同学,才感觉自己也该回教室比较好看些------
全班同学都回到了教室,好像说好了似的,很大一会大家谁也不说话,然后大家似乎都明白了什么,几乎是异口同声了:“我知道了,是因为大家不团结,没有合作精神。”找到了自己败的地方,同学们都说:“下次,我们不会放过二班”。我们都使劲点头。
这次比赛我们输在了不会合作上,下次我们该如何合作呢?同学们又商量开了。
第四篇
2016年河北省中考状元谈学习经验
张是卓河北省中考状元(15岁来自石家庄市28中)
总分633分 数学117分 语文113分 英语115分 文综114分 理综114分 体育30分 信息技术10分 实验操作10分 优惠加分10分
7月3日,石家庄市中考成绩公布,地处新华区的石家庄第二十八中学学子张是卓以总分633分的好成绩,成为2015年石市中考状元。身着白衬衫、留着小平头、个头儿一米八……在众多学子中,张是卓并不算显眼,但如果你跟他交谈起来,便会充满愉悦,因为他在张嘴说话前总会对你呵呵乐。张是卓是如此形容自己成为状元这事儿的:“是一场梦吧!”
他有主见
认为“学霸”都该学点特长
7月3日下午4时,张是卓急匆匆地往班主任盖春明的办公室跑,迎头撞上了学校教务处主任,教务处主任一句“你可能是市中考状元”把张是卓定在了原地。“这肯定不是真的,比我强大的同学有太多。”张是卓说。谈起平日学习的技巧,张是卓说庆幸自己生活在幸福的9年级15班,在这个班里,老师不以成绩论英雄,而是重视学生的全面发展。“因为这种理念在,我们班这些所谓的‘学霸’,每个人都有着自己的特长。”张是卓边说边举例,“杨晨宇同学是数学天才,篮球打得特好;‘文科一姐儿’李嘉琪读过超级多的书……”而张是卓,除了日常学习之外,每日还坚持长跑,小提琴拉得也是可圈可点。
张是卓将这种全面的发展称之为“螺旋式上升法”。他解释,只注重成绩的直线上升,短时间内固然能取得好成绩,但走不长。倒不如弹簧般的螺旋式上升,虽然每一次的进步都不明显,但有足够的时间让自己反思。
“初中的知识其实并不难,听老师话,不要偷懒就一定能取得好成绩。我是觉得,每个人都该学点特长,这样的全面发展能提升自信,对学习也好。”在中考状元张是卓看来,学习一定不是读死书,要像28中校训那样“深思活学。”
他爱较真
经常追着老师“刨根问底”
其实,在中考前的各种模拟考试中,张是卓的成绩一直在年级的7至15名之间,只考过一次年级第一。关于这次成为全市第一,班主任盖春明倒显得一点也不意外。
在盖春明老师看来,张是卓是一个很谦和、大气的孩子,是班里“老实孩子”的代表。平日里学习成绩很稳定,还担任班里的班长,只要是老师安排的事儿他肯定都能做好,一点都不偷懒儿。他还时常组织同学到户外进行公益活动,“组织能力一级棒,博览群书,在班里也很有威信。”听到班主任老师这么说,张是卓瞬间用手护住了双眼说:“老师你过奖了,我没那么好,杨晨宇一个小时写完的数学题,我都写仨小时。”听到张是卓这么说,盖老师轻轻敲打了一下他的背。身为“老实孩子”的张是卓在老师眼里,还有一个特点,就是“轴”!他爱刨根问底,一个问题如果解不出来,就一直追着老师问。曾经有老师用“笨”来形容他,但这个形容词里满是对他的褒奖。
张是卓可以将练习册里老师批改的题重新再做一遍,并且一点点地标注清楚,有些标记连老师看来都是“笨工夫”,不必如此,但张是卓乐此不疲。在张是卓看来,这些“笨工夫”做对了,他虽然单科成绩并不出众,但综合成绩一直很不错。“听每个老师的话,按照各科老师的节奏学习,我觉得挺好。”张是卓说。
他很幸运
爸妈像“哥们儿”一样尊重他
在张是卓成为市中考状元这件事上,有一个人一直表现得十分淡定,这个人就是张是卓的妈妈。
张是卓说他成绩相对一直优秀,离不开良好的家庭氛围。从他记事起,全家人就一起吃饭,无论做任何决定,爸妈都会听他的意见,并且很多时候他的意见都多多少少会被采纳。在他眼里,爸妈不是家长,更像是无话不说的“哥们儿”。
自从张是卓上学以来,是卓妈妈始终在做的就是了解他所在学校的教育理念。“我们家要和学校的教育理念保持一致,不然孩子不知道听谁的,对他的成长会有影响。”是卓妈妈说,孩子上了28中后,她专门研究了28中先进的教学理念,时刻与学校老师保持沟通。在张是卓的父母看来,他的学习成绩不重要,不要太差就好。孩子的身体和品质才是最重要的,所以从小张是卓就被爸妈拉着长跑,15年下来,“我的耐力特别好,就是跑步练出来的。”
7月3日,中考成绩公布仅半天,就已有很多人追着是卓妈妈问孩子要报考哪个学校,每次妈妈的回答都是:“我听儿子的啊,尊重他的选择。”

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。

【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。

第十五篇
父爱是山,呵护生命的火;父爱是火,点燃希望的灯;父爱是灯,照亮前行的路;父爱是路,引领你的一生。
曾经不懂父亲笔直的脊梁因何弯曲,不懂父亲俊朗的面容因何憔悴,不懂父亲浓黑的秀发因何斑白,不懂父亲大半辈子的辛劳究竟为谁……
直到初三。
那天狂风怒吼,草木萧条,我坐在公共汽车上准备下车后独自回家,可是,我却看见了一个人,黑压压的天下,凛冽的风中,那人不住地颤抖。风不停地掀翻他的衣角———是父亲!透过窗子,清晰地看见了父亲的白发,不是月亮清辉的点染,没有华丽的词藻的装饰,就是白发,是一根根、一片片的白发,父亲的白发,一次次被狂风压倒却又一次次不屈地挺立,那一倒一立中,我知道一定是为了谁……
那被不断压倒和挺起的究竟是父亲的白发还是父亲的心?车靠站点,我快步走下,显然,父亲望见了我,他不再用手指堵住进风的大衣,而是快步向我跑来,他的大衣彻底向狂风屈服了,但他却丝毫没有在意裸露出来的红色毛衣在这莫名的黑暗中跳动着,向我奔来。
那一刻,我分明看到了父亲严寒中向我靠近的那颗火热的心,那一刻,我一任泪水滂沱。
父亲轻轻携起我的手想使我的手暖和起来,但我触到的分明是冰一样凉的大手,我紧紧地将父亲的手攥住,父亲却忙躲开,“我的手太凉了。”我不顾父亲的躲闪,一把抓回那双冰凉的大手,我知道:我抓住的是我这一生的财富。
父亲用生命的衰老化作山,化作火,化作灯,化作路,化作一点一滴的父爱,陪伴我每一天、每一秒,陪伴我这一辈子。父亲啊,你的爱是女儿一生的财富,因为有了你的爱,女儿一生不会贫穷。
