第二篇:河北衡水中學(xué)專題
河北衡水中學(xué),一直與“北大”、“清華”、“狀元”、“奇跡”等詞匯聯(lián)系在一起,從2008年至2011年,衡水中學(xué)考入清華、北大278人,每年有大量學(xué)生考上名校,被稱為“大學(xué)生加工廠”。
由來
從2008年至2011年,河北衡水中學(xué)考入北大清華的學(xué)生有數(shù)百人,被稱為超級(jí)中學(xué)。衡水因此吸引了周邊地市的大量“尖子生”。衡水的秘訣就是把學(xué)生做題的潛力挖掘到極致,學(xué)生連等待打飯的時(shí)間都要被利用做題。河北教育廳官員稱,衡水充其量只是一個(gè)大學(xué)生的加工廠。
成績
2011年,這所學(xué)校向北大清華輸送70人,并占據(jù)河北省高考前200名中的一半。2011年的高考,該校的成績近乎瘋狂:除包攬河北省文理科第一名,還有7人、6人分別進(jìn)入省文理科前10名。數(shù)年來,衡中保持著優(yōu)異的高考成績。在其帶領(lǐng)下,衡水各中學(xué)的高考成績也突出于河北其他地市。
衡水模式
“衡水中學(xué)把學(xué)生做題的潛力挖掘到極致了?!毙吓_(tái)的一名高中教師,這樣評(píng)價(jià)“衡中經(jīng)驗(yàn)”。
衡水中學(xué),每天13節(jié)課,6節(jié)正課,由老師上課講解;7節(jié)自習(xí)課,大部分時(shí)間用來做題。上述邢臺(tái)的高中老師說,他聽學(xué)生講,“衡中的學(xué)生,連等待打飯的時(shí)間都要被利用上做題”。
除學(xué)科自習(xí)外,其他自習(xí)課,老師不允許進(jìn)教室。在學(xué)科自習(xí)上,老師也不允許統(tǒng)一講解。對(duì)學(xué)生單一輔導(dǎo)時(shí),老師的聲音放到最低,不能影響其他人。到高二結(jié)束,基本學(xué)完高中課程,高三全年都在復(fù)習(xí)。復(fù)習(xí)有三輪,各有重點(diǎn)。同時(shí)會(huì)做大量模擬考題。因高考成績優(yōu)異,衡中的高三習(xí)題被傳得很神秘。衡水中學(xué)不用市面上現(xiàn)成的習(xí)題,宣傳處主任張永介紹,衡中的習(xí)題都是經(jīng)過老師精心挑選的。
精神激勵(lì)
衡水中學(xué),隨處可見標(biāo)語口號(hào)。它們分布在校園路上,教學(xué)樓大廳里的倒計(jì)時(shí)牌上,學(xué)生宿舍,甚至學(xué)校印刷的筆記本上也有。班級(jí)墻上的標(biāo)語有,“血狼精神,與我同在”,“今日瘋狂,明日輝煌”。
在高二年級(jí)教學(xué)樓,大廳墻上有三句話:“我來衡中做什么,我要做一個(gè)什么樣的人,我今天做得怎么樣?!边@被稱為每日“三思”。
跑操時(shí)喊的口號(hào):“超越自我,挑戰(zhàn)極限”、“放飛青春,勇攀高峰”、“自強(qiáng)不息,志與天齊”,班級(jí)旗幟上的標(biāo)語是“為夢(mèng)想浴血奮戰(zhàn)”。
衡中口號(hào)每年都不一樣,2011年的標(biāo)語和2010年就不同,其倒計(jì)時(shí)牌上寫著,“十二載潛心鑄劍,今朝及鋒而試”;樓道上的橫幅則是,“萬念歸一,用虔誠追求夢(mèng)想”。
衡水效應(yīng)
“衡水現(xiàn)象”備受矚目,衡水中學(xué)不僅在當(dāng)?shù)卣猩€吸引周邊地市的大量“尖子生”。一位來自石家莊的學(xué)生說,他們班上,有20來個(gè)外地同學(xué);還有學(xué)生說,他們班上還有從北京來的。邢臺(tái)的高中老師認(rèn)為,“衡中的教學(xué)模式嚴(yán)重踐踏了中國的高中教育”,但讓他矛盾的是,在目前的考試模式下,“誰不學(xué)衡中,誰就將被徹底淘汰”。
教育質(zhì)疑
“衡水模式”備受爭議。批評(píng)的聲音認(rèn)為,軍事化的備考,題海戰(zhàn)術(shù),讓學(xué)生麻木,扼殺創(chuàng)造力。
某縣委書記曾給這所中學(xué)送了塊匾,上書“人才的搖籃”。但河北省教育廳一位官員并不認(rèn)同:你別說培養(yǎng)的是人才,充其量只是一個(gè)大學(xué)生的加工廠。高考只顧及了人才培養(yǎng)的某一方面,標(biāo)準(zhǔn)是分?jǐn)?shù),而高中教育中,訓(xùn)練越多,錯(cuò)誤越少,扣分就越少?!昂馑F(xiàn)象”最大的特征就是,“對(duì)高考這個(gè)目標(biāo)的管理特別有效”

班級(jí)旗幟上的標(biāo)語:“為夢(mèng)想浴血奮戰(zhàn)”
教學(xué)樓大廳墻上的“三思”標(biāo)語:“我來衡中做什么,我要做一個(gè)什么樣的人,我今天做得怎么樣?!?/p>
跑操時(shí)喊的口號(hào):“超越自我,挑戰(zhàn)極限”、“放飛青春,勇攀高峰”、“自強(qiáng)不息,志與天齊”
樓道上的橫幅:“萬念歸一,用虔誠追求夢(mèng)想”
信息時(shí)報(bào)訊 據(jù)《新京報(bào)》報(bào)道,6月5日,臨近中午,衡水中學(xué)高三430班,教室里偶有翻書聲,學(xué)生們低頭學(xué)習(xí)。
教室墻上掛著紅色條幅,“血狼精神,與我同在”,這是班級(jí)“信條”。后面墻的黑板上,寫著“今日瘋狂,明日輝煌”。
幾年來,河北這所“超級(jí)中學(xué)”,一直與“北大”、“清華”、“狀元”、“奇跡”等詞匯聯(lián)系在一起。
去年高考(微博),衡水中學(xué)考取清華、北大70人,占兩所學(xué)校在河北招生人數(shù)的一半左右。
再之前,從2008年至2011年,衡水中學(xué)考入清華、北大278人。
如今,“衡水現(xiàn)象”備受矚目,衡水中學(xué)不僅在當(dāng)?shù)卣猩?,還吸引周邊地市的大量“尖子生”。一位來自石家莊的學(xué)生說,他們班上,有20來個(gè)外地同學(xué);還有學(xué)生說,他們班上還有從北京來的。
作為高考制度下的蛋,衡中的秘訣在哪,高強(qiáng)度訓(xùn)練適應(yīng)考試,是否扼殺學(xué)生創(chuàng)造力,是否踐踏教育本身——“衡水模式”被輿論關(guān)注和解析。
“衡水”輝煌
10年來,到“衡中”學(xué)習(xí)的外地官員、師生約17萬人
5月27日,李梓華(化名)坐了5個(gè)多小時(shí)火車,從唐山到衡水中學(xué),路途輾轉(zhuǎn)。
李梓華是初三學(xué)生,以她的成績,能考上當(dāng)?shù)刂攸c(diǎn)高中。但去年,當(dāng)?shù)馗咧袥]有一個(gè)學(xué)生達(dá)到清華的錄取線。
李梓華想上清華,所以到衡水中學(xué),咨詢是否能來讀高中。
衡水中學(xué)位于衡水市區(qū)東南部,周圍與平房相伴。其破舊的大門和斑駁的墻壁,很難看出這里有多么特別。
但是,貼滿清華北大學(xué)生照片的校園圍墻,綿延近百米;校門口,還有兩幅巨大的高考成績宣傳展板。
2011年的高考,該校的成績近乎瘋狂:除包攬河北省文理科第一名,還有7人、6人分別進(jìn)入省文理科前10名。在省前200名中,衡水中學(xué)的學(xué)生占了近一半。
有人開玩笑說,在這個(gè)開車半小時(shí)就能穿越的小地級(jí)市,沒有幾個(gè)熟人上清華北大都不好意思出門。
衡水中學(xué)宣傳處主任張永說,在河北,衡水高考成績已遠(yuǎn)超過其他地區(qū)了。這跟衡水經(jīng)濟(jì)在河北省的排名非常不相稱。
因?yàn)楹馑呖汲煽兺怀?,一個(gè)全國性的高中校長論壇決定在衡水中學(xué)舉行。校長張文茂一再要求減少參會(huì)人數(shù),原因是“衡水市區(qū)的賓館住不下”。
去年衡水中學(xué)承辦會(huì)議,即使賓館都被包下來,還是有不少與會(huì)者需要到幾十公里以外的縣城住宿,很不方便。
張永笑稱,衡水中學(xué)為衡水的賓館作出了很大貢獻(xiàn)。10年來,單單是來衡水中學(xué)參觀學(xué)習(xí)的外地官員、師生就有17萬人,他們一住就是幾天,這是筆不小的收入。
“做題潛力挖到極致”
有老師稱,衡中學(xué)生,連等待打飯的時(shí)間都要被利用做題
“他們到底有什么絕招?一句話,衡水中學(xué)把學(xué)生做題的潛力挖掘到極致了?!毙吓_(tái)的一名高中教師,這樣評(píng)價(jià)“衡中經(jīng)驗(yàn)”。
衡水中學(xué),每天13節(jié)課,6節(jié)正課,由老師上課講解;7節(jié)自習(xí)課,大部分時(shí)間用來做題。上述邢臺(tái)的高中老師說,他聽學(xué)生講,“衡中的學(xué)生,連等待打飯的時(shí)間都要被利用上做題”。
“用各種各樣的方式重復(fù)。”一名曾在衡水中學(xué)教語文的老師說。
除學(xué)科自習(xí)外,其他自習(xí)課,老師不允許進(jìn)教室。在學(xué)科自習(xí)上,老師也不允許統(tǒng)一講解。對(duì)學(xué)生單一輔導(dǎo)時(shí),老師的聲音放到最低,不能影響其他人。
上述語文老師介紹,到高二結(jié)束,基本學(xué)完高中課程,高三全年都在復(fù)習(xí)。復(fù)習(xí)有三輪,各有重點(diǎn)。同時(shí)會(huì)做大量模擬考題。
因高考成績優(yōu)異,衡中的高三習(xí)題被傳得很神秘。衡水中學(xué)不用市面上現(xiàn)成的習(xí)題,宣傳處主任張永介紹,衡中的習(xí)題都是經(jīng)過老師精心挑選的?!霸瓉碜?套題才能達(dá)到的效果,現(xiàn)在做一套就行了”。
對(duì)于題量,曾經(jīng)有個(gè)說法:如果一套題70%的學(xué)生答完了,那就是不合格的,因?yàn)檫@說明很多學(xué)生的時(shí)間被浪費(fèi)了。
“每天反省很必要”
學(xué)校的氛圍讓學(xué)生覺得,“不好好學(xué)習(xí),對(duì)不起同學(xué)”
因?yàn)閵W賽獲獎(jiǎng),衡水中學(xué)高三學(xué)生李秋宇已被保送清華大學(xué)(微博)。這些天,他沒離開學(xué)校,他成了“老師”,負(fù)責(zé)輔導(dǎo)高二奧賽練習(xí)。
李秋宇喜歡“有規(guī)律的生活”:早上5:30起床,然后跑早操。
衡水中學(xué)高二學(xué)生王奕文也喜歡跑操,認(rèn)為喊口號(hào),“很提神”。
她說每天早晨5點(diǎn)半起床并不難,聽到鈴聲就會(huì)醒,這是“條件反射”。然后十分鐘洗漱,開始跑步。
跑步前,有大概5分鐘的集結(jié)時(shí)間。這個(gè)時(shí)間她和同學(xué)們都會(huì)帶著學(xué)習(xí)資料,“背一個(gè)單詞都是收獲”。“從這一天開始,就要把思維帶到學(xué)習(xí)上來?!?/p>
之后是語文和英語的早讀時(shí)間。王奕文說,大聲朗讀,會(huì)幫助提神。
由此,全天13節(jié)課開始,直到晚上10點(diǎn)半。有學(xué)生說,學(xué)校的氛圍讓他覺得,“不好好學(xué)習(xí),對(duì)不起同學(xué)”。
這樣的作息時(shí)間,在衡水的各所高中,基本是通用的。
在衡水中學(xué)高二年級(jí)的教學(xué)樓,大廳墻上有三句話:我來衡中做什么,我要做一個(gè)什么樣的人,我今天做得怎么樣。這被稱為每日“三思”。
衡水中學(xué)宣傳處主任張永說,對(duì)于高一高二的學(xué)生,“每天的反省很有必要”。
“天下第一操”
學(xué)生跑操“有一股子壓倒一切的氣勢(shì)”
高一到高三,衡水中學(xué)的學(xué)生們,吃、住都在校園,每兩周放假過一次周末。
在不放假的周末,學(xué)生們要和平時(shí)一樣學(xué)習(xí)。
據(jù)介紹,在衡水市,另有一些高中,一個(gè)月放一次周末假。
“跑操”,是衡水中學(xué)的一個(gè)符號(hào),相關(guān)視頻在網(wǎng)上流傳后,被稱為“天下第一操”。
跑操的時(shí)候,每個(gè)班學(xué)生組成一個(gè)方陣,繞操場(chǎng)跑圈。隊(duì)伍緊湊,間距一致,步伐一致,速度一致。除了喊“一二三四”,還喊著“超越自我,挑戰(zhàn)極限”等口號(hào)。
張永說,不做廣播體操,是因?qū)W生多,場(chǎng)地不夠,學(xué)生又要鍛煉身體,只能跑跑步。結(jié)果,現(xiàn)在其他學(xué)校都在學(xué)“跑操”。
前任校長李金池說,北京海淀的高中校長團(tuán)曾到該校參觀。聽說大課間不做廣播操而是跑操,非要親眼看一看。
“看著看著,幾位校長忽然掉下了眼淚”。李金池說,對(duì)方稱是激動(dòng)的,“你們學(xué)生有一股子壓倒一切的氣勢(shì)”。
老師節(jié)假日基本不休息
月薪三四千元,超過當(dāng)?shù)毓珓?wù)員(微博),但工作時(shí)間是公務(wù)員的兩倍
王亞玉是去年河北省的理科高考狀元,她說其實(shí)我沒什么特別,在衡水中學(xué),真正值得關(guān)注的是那些老師。
衡水中學(xué)的老師,每月工資三四千元,超過當(dāng)?shù)毓珓?wù)員。老師們說,這份薪水建立在近乎公務(wù)員兩倍工作時(shí)間之上。
備課很重要。因?qū)W生大部分時(shí)間是自習(xí),每門課每天一節(jié)正課40分鐘,老師們需要在極短時(shí)間內(nèi)講清楚必講內(nèi)容。
從學(xué)生早讀開始,任課老師就要進(jìn)入工作狀態(tài)。如果是班主任,工作時(shí)間還要提前,有的要陪學(xué)生跑早操。
每天下午5點(diǎn)半下班,之后至晚上9點(diǎn)半,是老師們的彈性工作時(shí)間。
除了備課,老師們要出很多習(xí)題,并判卷。為了了解習(xí)題的深淺,老師要把習(xí)題都做一遍。

踐踏教育成就高考?
“衡水”軍事化備考亦引發(fā)爭議;專家稱,只要高考不改,衡水模式就會(huì)存在 “衡水現(xiàn)象”,吸引了周邊地市的大量“尖子生”前來就讀,甚至還有北京的學(xué)生。
記者了解到,北京在高考自主命題前,有很多北京學(xué)生來衡水中學(xué)讀書,如今仍有個(gè)別北京學(xué)生。
據(jù)介紹,河北其他地方的一些校長和教育主管部門負(fù)責(zé)人,一邊向衡水學(xué)習(xí),一邊向省里寫信舉報(bào)。他們認(rèn)為,衡水跨區(qū)域招生,影響教育均衡。
河北省教育廳基礎(chǔ)教育處正處級(jí)調(diào)研員李強(qiáng),專注高中教育研究10多年了。他說他理解其他地市的苦衷:“尖子”走了,升學(xué)率受影響。
李強(qiáng)介紹,2003年以來,河北省教育廳出臺(tái)過限制措施,不過這些規(guī)定其實(shí)“底氣不足”?!拔覀兛紤]的是,規(guī)范一下秩序,大家不要亂來”。
李強(qiáng)說,他也私下“敲打”那些“告狀的”學(xué)校:你們那里的孩子都跑了,他們背井離鄉(xiāng)到別的地方求學(xué),付出了更多的成本,這是你們的罪過。
在學(xué)生們往衡水跑的同時(shí),“衡水模式”也備受爭議。批評(píng)的聲音認(rèn)為,軍事化的備考,題海戰(zhàn)術(shù),讓學(xué)生麻木,扼殺創(chuàng)造力。
上述邢臺(tái)的高中老師認(rèn)為,“衡中的教學(xué)模式嚴(yán)重踐踏了中國的高中教育”,但讓他矛盾的是,在目前的考試模式下,“誰不學(xué)衡中,誰就將被徹底淘汰”。
縣委書記給這所中學(xué)送了塊匾,上書“人才的搖籃”。但李強(qiáng)并不認(rèn)同:你別說培養(yǎng)的是人才,充其量只是一個(gè)大學(xué)生的加工廠。
河北省教育廳一名工作人員認(rèn)為,衡水適應(yīng)了目前的高考制度,只要高考不改,這個(gè)模式就會(huì)存在。

B Donald John Trump(born in June 14,1946),is an American businessman and politician who became the President-elect of the United States on November 8,2016.Since 1971 he has chaired The Trump Organization,the principal holding company for his real estate ventures and other business interests.During his business career,Trump has built office towers,hotels,casinos,golf courses,and other branded facilities worldwide. Trump was born and raised in New York City and received a bachelor’s degree in economics from the Wharton Schoo1 of the University of Pennsylvania in 1968.In 1971,he was given control of his father Fred Trump’s real estate and construction firm.Trump has appeared at the Miss USA pageants,which he owned from 1996 to 2015,and has made cameo appearances in films and television series. Trump and his businesses,as well as his three marriages,have received prominent media exposure.He hosted a popular NBC reality show,The Apprentice,from 2004 to 2015.As of 2016,he was listed by Forbes as the 324th wealthiest person in the world,and 156th in the United States,with a net worth of $3.7 billion in October 2016. Trump first campaigned for the U.S.presidency in 2000,winning two Reform Party primaries.On June 16,2015,Trump again announced his candidacy for president,this time as a Republican.Trump became known for his opposition to illegal immigration and free trade agreements,as well as his frequently non-interventionist views on foreign policy,and quickly emerged as the Republican nomination front-runner.As of March 23,2016,Trump has won 21 contests in the 2016 Republican presidential primaries.
He was elected as the 45th U.S.president in the 2016 election on the Republican ticket,defeating Democratic nominee Hillary Clinton,and took office on January 20,201 7.At 70 years old,he is the oldest person to ever assume the presidency.
24.This passage is mostly probably taken from__________. A.a(chǎn) story book B.a(chǎn) biography book C.a(chǎn) science book D.a(chǎn)n advertisement 25.Where is Donald Trump’s hometown?
A.London. B.Paris. C.New York. D.Beijing.
26.From the passage,we can know that Donald Trump was________. A.wealthy and Successful B.intelligent but mean C.good-tempered and tolerant D.forgetful and sensitive 27.We can 1earn from the passage that_________. A.Donald Trump is only successful in business field B.Donald Trump was born in a poor family C.Donald Trump is in favor of illegal immigration D.Donald Trump is the oldest president of the United States C It is reported that in the near future robots and humans will probably work together to create jazz.A singing robot is being taught to create jazz with human being in a project.
Antonio Chella from Italy is working with a Telenoid robot.To start with,the Telenoid will be trained to imitate(模仿)the movements and simple sounds made by a human singer,and then connect music with different human
.
Previous robots had the ability to find common connections between things.But Chella suggests that a conscious robot should be able to go a step further and find new connections.The Telenoid is of this kind.“This work raises interesting questions about the connection between consciousness and music creating,”says Philippe Pasquier.A musician needs a physical body.
Pasquier argues that the robot musician is faced with a big challenge.“Its software has already been developed and it can imitate The Beatles,a famous band.However,what made The Beatles famous were not only their songs but their wonderful performance of the songs,”he says.
It is not clear how a robot would perform music in a new way.But by imitating humans,the Telenoid robot could provide some useful information.What is important is that human musicians often listen to and c ompare music made by others for a long time before creating music of their own.So the Telenoid robot had better listen to more jazz music first.
28.What will the Telenoid robot be taught to do first? A.Communicate with human beings. B.Connect music with human emotions.
C.Live and work comfortably with human beings.
D.Imitate the movements and simple sounds of a human singer. 29.In Pasquier’s opinion,the Telenoid robot________.A.will replace human musicians soon B.may have trouble performing music C.will become more popular than The Beatles D.can find connections between things that humans cannot find 30.Which of the following could be the best title of the passage? A.The Telenoid,future robot musician. B.How to teach robots to perform music. C.The right music the robots should listen to.
D.Differences between a human singer and a robot musician.
31.In which part of a newspaper would we most probably read this passage? A.Arts. B.Entertainment. C.Science. D.Education. D I am reading a novel at the moment,a s tory set in Britain and India in the 19th century.It was written by an Indian author who now lives in Denmark,but neither in the language of Hindi nor Danish.Although the paperback edition I’m holding was published in New Delhi,India,four years ago,I(an American)purchased it recently from a second-hand bookshop in Tokyo,Japan.
That’s quite a history already.But there’s more.
The novel is a tale of various mysteries,all expertly put into a well-structured story by a very,skillful author.Yet my particular copy presents even more mysteries than the tale.
One summer morning in the year of my paperback’s publication—on July 15,2012—someone else was reading it while eating breakfast in a restaurant in Mumbai,India.
I know this because I found a receipt(收據(jù))of coffee and bread inside.I also know that this person was not the owner of the paperback immediately before me.
In fact,the owner before me was not Indian at all,but Japanese.
I know this because in the book there are handwritten notes in Japanese—translations of English words which the reader was unfamiliar.Japanese being a language of characters,not letter,it is not easy to determine if the note writer was a man or a woman.But the care taken to write the translations neatly in the limited spaces available on each page bespeaks a woman’s hand.
So let us agree that it is a woman.What can we say of her? Well educated,obviously,and probably a university student,who would keep a dictionary at hand while reading a novel.
But why did she suddenly stop reading? The last translation in my paperback appears on Page 83,less than a
.Did she give up because the book was proving too difficult? Or was there some other reason? Many a novel presents mysteries,all of which are solved by the end of the tale.The mysteries presented by my little paperback,however,remain mysteries,all expertly put into a well-structured story,not by a skillful writer,but this time by the numberless vagaries(變幻莫測(cè))of life itself. 32.What can we learn about the novel? A.It is well written.
B.It is about a world trip.
C.It was written in an American res taurant. D.It was first published in the 19th century.
33.The author assumes the Japanese owner of the book was a woman based on_______.A.the pretty handwriting B.the food written on the receipt C.the good co ndition of the book D.the effort taken in writing the notes 34.Which of the following can best describe the author? A.He is a great reader of historical fiction. B.He is a hard-working university student. C.He is a productive writer with sensibility. D.He is a careful observer with imagination. 35.W hat’s the best title of the text?
A.The Tale of a Paperback B.Different Life Experiences C.Unsolved Mysteries of Life D.A Book’s Exciting Adventure 第二節(jié)(共5小題;每小題2分,滿分10分)根據(jù)短文內(nèi)容,從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。Choosing the Right Path to Be a“Better”Person
Life is a constant exercise in self-improvement.In the rush to achieve,the idea of being“better”can become lost sometimes.You may always wonder how to improve yourself and fulfill your dreams in an easier way. 36 Explore your talents.
Everybody has some outstanding skills or interests.So it’s often necessary to be patient and try many things before you find one that suits you.
For example,people loving adventure may not be interested in the quiet chess club,but someone who enjoys other quiet activities might be.Determining who you enjoy being around may help you know what you’11 enjoy. 38 No matter how much money you make.you will not be happy if you spend your entire life doing somethi ng you hate.It’s important to at least devote some of your time to what makes you happy.
If you’re particularly unhappy at your job,consider why. 39 If you feel your job isn’t meaningful,or isn’t in line with your values,consider finding another job. Experience something new.
Research has shown that when we’re in our comfort zone,we aren’t as productive as we are when we step just beyond it. 40 Because of that,we may react slowly to our own positive experiences and interactions with others,even when those are little scary.Doing so can help you achieve more.
A.Do what you love.
B.Here are some tips for you.
C.Register in a class you’re interested in.
D.Humans adapt very quickly to positive events.
E.It’s possible that some changes may change your feeling.
F.Similar types of people may be attracted to the same activities.
G.Try not to allow yourself to focus so much on a certain aspect of your life. 第三部分 語言知識(shí)運(yùn)用(共兩節(jié),滿分45分)

At primary school in New Zealand,I was introduced to a school savings account run by one of the local banks.When our money box was 41,we took it to the bank and watched with 42 as our coins flowed across the counter.As a 43,we could choose our next money 44 from a small variety,and start the whole savings 45 again.Every week I watched my parents 46 the housekeeping(家務(wù)開支)and“make ends meet”.Sometimes it was 47 to wait for things we really felt we needed. Later,as a university student,I 48 on an extremely small student allowance.Students were 49 by banks then,because we were so 50 and there was no way I could have gotten credit,even if I had tried.We 51 our allowance three times each year,put it into a bank to the best advantage and withdrew it little by little to last 52 the next payout of the allowance.
When our daughter,Sophie,began to walk,we made a purposeful choice to encourage her to use money 53 .We often comment when the TV tells us“You 54 it to yourself to borrow our money”—to whom do we really owe it?

Have you ever noticed how hard it can be to find the right words? I have,frequently.And there are times 61 I am certain the right words do not even exist.
More than once I 62(call)to a hospital emergency room or to be with a family around the bed of a dying relative. And more than once I’ve been at a loss for words.
A wise doctor at 63 university teaching hospital once made a comment about comforting those who suffer.Someone asked the doctor what advi ce he offered his students,the future doctors and nurses,when 64(care)for mothers who gave birth to stillborn babies.The doctor paused 65 a moment in thought.Then he said,“I tell them that they need two eyes.With one eye they have to check the drip(滴注器).And with the other eye they have to weep.That’s what I tell them.”
That may be some of the 66(wise)advice I’ve ever heard.We may not always need to figure out what to say;we really only need two eyes.The words 67(write)by Emily Dickinson read,“Saying nothing…sometimes says the most.”It says I want to be 68(full)present with them and walk alongside them,difficult 69 it may be.My presence is something they can draw real 70(strong)and hope from. 第四部分 寫作(共三節(jié),滿分45分)第一節(jié) 詞匯運(yùn)用(共10小題;每小題1分,滿分10分)根據(jù)下列句子所給漢語意思或括號(hào)里的單詞完成句子,使得句意通順、語法正確。71.These_______(apply)can only apply for the position as a secretary. 72.Dolly’s appearance raised a storm of ______(object). 73.Heavy smoking makes him______(breath).
