WhenKatherine Chon was in fifth grade.she drew a“dream tree”erepresenting the path she
hopedher life would take.One branch led to Harvard Medical School，Which isexactly what her
motherhad hoped for when the Chons moved to the U.S.from SouthKorea to give their three children opportunities.
Always adiligent student，Katherine started to learn medicine at Brown.But then sheadded a
new limbto her dream tree—one mat her mother still doesn’t understand.Shocked bythe misfortune of some South Korean women，Katherine joinedforces with another Brown student to form the Polaris Project，now one ofthe largest anti-human-trafficking organizations in the country，“It wasreally hard for my parents，”says Katherine.“They had so many life stresses so their children could、get a greateducation and have a comfortable life.”
Thedreams of parents and children often differ，but the conflict canbe especially painful in
first-generationimmigrant families where the parents have made enormous sacrifices.Lisa Park，an assistantprofessor at the University of California，San Diego，says that：the focus ofevery family that moves to the United States to provide opportunities for theirchildren is almost always on the future，with little mentionof the circumstances that compelled them to move.And even though the parentsare the ones working 12-hour days，the children ale also under intense pressure to perform in ways thatwill justify the parents’ sacrifice.
Thecontrast between parents’ dreams andchildren’s realities can be particularly sharp for
daughterswho have grown up with almost infinite opportunities.Theirmothers often came from
placeswhere opportunities for women were limited，which makes thedaughters’ choices even harder tounderstand.Mary Lugemwa’s parents encouraged her to study math or science atHarvard.
Shecomplied at first，majoring in computer science.But she is currentlyworking as a film producer for a nonprofit organization called Meaningful Media.“I sometimesfeel guilty，”she says，
“having chosen,to bean artist，because I know that if I had chosen a scientific background，I could helpmy parents a lot more.”

MothersAgainst Drunk Driving(MADD)has launched a new public awareness campaign aimedat Canadian Justice Minister Irwin Cotler.“Enough is Enough”advocatesdropping the Criminal Code’s blood alcohol concentration(BAC)limit from 0.08 to 0.05 percent，to“protectinnocent drivers on our roads.”MADD Canada CEO Andrew Murie thinks tllat lowering the BAC limitcould result in a 6-to-18 percent reduction in crash deaths.Butquestions have been raised about the science behind that campaign.
MADDselectively cites a report published in 2002 by Robert Mann of the MentalHealth
Centre.Mama，in turn，had gotthose numbers from two separate studies whose data was selected from Sweden andAustralia.The conclusions in Mann’s report seem to ignore the Swedish authors’numerouswarnings and cautions，as well as the limitations in the Australian study.First，theAustralian study examined the effectiveness of breath testing，not loweredBAC levels，on fatal traffic crashes.Also.thatresearch was started in 1976 when“liquid lunches”were far more common.What’s more.the Australian data varied：whereas the state ofQueensland saw the 18 percent decline in fatal accidents cited by MADD’s Murie，inneighboring New South Wales，fatal accidents decreased just 8 percent.
It isalso reported by the Ontario Community Council that the majority of drivers inalcoholrelated fatal erashes are repeat offenders with BACs over 0.15percent-meaning that the problem is drivers who repeatedly get behind the wheelwith BAC levels twice the legal limit.not social drinkerswho consume a glass of wine or tw0.This makes MADD’sconcern seem wasteful，given the downward trend in alcohol-related tramc deaths.
TheCanada Safety Council，the Canadian Council of Motor Transport Administrators and theTraffic Injury Research Foundation take issue with MADD’s campaign.Even theOntario Community Council has determined that lowering the BAC would mean morework for police and the courts.
But toMADD’s Murie，the math question is simple：“If you lower BAClimits，regardless to what
level，you’ll saveCanadian lives.”Unfortunately，the math doesn’t quite add up.
51.MADDlaunched a public awareness campaign in order to_______.
[A]criticizethe Justice Minister
[B]improve BAC measurement
[C]restrictdrivers’access to alcohol
[D]revise the law regarding drunk driving
52.From thetext we learn that MADD cites a report that________.
[A]justifiesits new campaign
[B]is favored by the authorities
[C]sumsup major public concerns
[D]is mentioned in two other studies
53.It isimplied in the text that Mann’s report is unreliable because_______.
[A]itwas based on some unsound research
[B]itgot its data from two inconsistent studies
[C]itwas written in conditions no longer valid
[D]itignored the limitations of the studies cited
54.The textindicates that MADD’s campaign_______.
[A]willnot affect social drinkers
[B]mayturn out to be of little value
[C]isgoing to reduce governmental labor
[D]haswon support from some organizations
55.The writer’sattitude towards the campaign is_______.

A recentstudy demonstrated how powerful a few words can be：Fortycompetitive tennis players were shown digital images of balls coming their way.Just beforeeach ball appeared，the players
saw orheard comments like“Good shot”or“Bad shot.”The reaction times of players hearing
negativeremarks were measurably slower.And these were athletes who trained frequently to play a consistentgame and not make unforced errors.
What isthe explanation? Negative feedbackweakens anyone’s belief in his or her ability to
succeed.But if youcan hold on to a winning attitude，you’ll make a greater effort and also create
positivedrive.Confident people inspire others;opportunities seemto come their way more often.
Theybecome magnets for success.
Learnthe importance of giving yourself pep talks,and keep the voice in yourhead positive.
The bestathletes，success is rarely due to raw talent alone.It’s becausethey’re simply better pre。
pared.They stayfocused，they’re willing to work as、hard as they need to，and theykeep the positive voice in their heads switched on.
Perhapsthe most important aspect of being your own coach is to do what any outside adviserora good parent.for that matter--would preach：practice，practice，practice.Avoidindividuals
who suckyour energy and diminish your confidence.Hang out with thepeople who see you at your best.and remind you about it very often.Pessimists drag youdown，as do whiners and critics.If there，s onewinning behavior that people building confidence should model，it’s thewillingness to get back into the game after a setback.Don’t nurseyour wounds.
Thereare，however，important warnings.Panicking can compound a small misstep by causing
you tolose your head and forget to think clearly.If you suffer aterrible loss，give yourself time to
absorbthe blow.Don’t deny the hurt or try to solve the problem immediately.Gather yoursupport system around you and simply get nurtured.Sitting around andthinking about your loss is the worst thing you can do to solve your problem.

凱瑟琳·千在上小學五年級時，畫了一棵“夢想樹”，這棵樹代表了她期待自己未來生活將要走的道路。其中一個枝干表示她想讀哈佛大學醫學院，而這個夢想確切地說是她媽媽對她的期待。千氏夫婦帶著孩子從韓國移民到美國主要是為了給他們的三個孩子提供更多的機會。
凱瑟琳一直是個勤奮的學生，并曾在布朗大學學習醫學。然而她在“夢想樹”上又增加了一個新的枝干，并且她媽媽對她這個新的夢想很不理解。凱瑟琳由于對一些韓國婦女的不幸遭遇感到很震驚，因此和布朗大學另外一個學生共同組建了“北極星項目”組織，該組織周前是美國國內最大的反人口販運組織之一。凱瑟琳說：“我爸媽真的非常辛苦，他們承受著各種各樣的生活壓力，目的就是讓自己的孩子受到好的教育，過上舒服的日子。”
父母和孩子的夢想總是不同的，但是在父母做出巨大犧牲的第一代移民家庭中，父母和孩子彼此間的沖突尤為劇烈。加州大學圣地亞哥分校助理教授麗薩·帕克談到，為了給孩子提供更多的機會而移民到美國的家庭幾乎只關注自己家庭未來的發展，很少提及當初迫使他們做出移民決定的其他因素。既然父母都一天工作l2個小時，那么孩子們也要頂著巨大的壓力去表現，因為只有這樣他們才能對得起父母的犧牲。
對于那些成長在面對無限機遇環境下的女孩子們來說，父母的夢想和自己的現實所形成的反差尤其顯著。她們的母親大多來自一些婦女獲得各種機會受限的國家，因此她們對于女兒的選擇更難理解。瑪麗·路姆娃的父母鼓勵她去哈佛學數學或科學。剛開始，她順從了，主修計算機科學。但現在她在有意義媒體這個非盈利性組織擔任制片人。她說：“選擇成為一名藝術家有時讓我感到很內疚，因為我知道如果我選擇一個有科學背景的行業，能幫到父母更多。”
46.B【精析】細節題。根據第一段第一句和第二句
“When Katherine Chon was in fifth grade，she drew a“dream tree”representingthe path she
hopedher life would take.One branch led to Har
vard Medical School…”可知凱瑟琳從小就立志上哈佛大學醫學院，可見“她對未來有清晰的規劃”，故選B。
47.A【精析】推理題。第一段提及凱瑟琳媽媽希望她學醫，第二段提及媽媽對其成立北極星組織不理解，可推知“凱瑟琳的媽媽對女兒的決定感到很失望”，故選A。
48.D 【精析】細節題。根據第三段第一句“The dreams of parents and children often differ，but the coflict can be especially painful…sacrifices.”
可知，“父母和孩子的夢想總是不同的，但是在父母做出巨大犧牲的第一代移民家庭中，父母和孩子彼此間的沖突尤為劇烈”，由此可知如果孩子違背了父母的愿望，父母會感到很受挫，故選D。
49.D【精析】細節題。根據第三段最后一句“And even though the parents are the onesworking 12 hour days，thechildren…that will justify the parents’sacrifice.”可知，父母一天工作12個小時，孩子要對得起父母做出的犧牲。由此可知孩子為了對得起父母的辛苦，要頂著巨大的壓力努力實現父母的夢想，故選D。
50.C【精析】推理題。根據最后一段對瑪麗·路姆娃這個故事的描述可知，她開始時順從父母的愿望，后來違背父母愿望，做自己喜歡的工作，由此可推知得出，她和父母有著截然不同的生活觀，故選C。

反對醉駕母親協會發起了一場新的公共意識運動，這場運動針對的是加拿大司法部長歐文·科特勒。為了保護路上無辜的司機。“適可而止”運動提倡將有犯罪代碼之稱的血液酒精濃度的限制由0.08%下調至0 05%。加拿大反對醉駕母親協會首席執行官安朱·梅利認為，調低血液酒精濃度限制有助于減少6%到l8%的交通死亡人數。但隨之這場運動背后的科學性問題也被提出來了。
反對醉駕母親協會隨機引用了心理健康中心羅伯特·曼于2002年發表的一篇報告中的內容。然而，曼所得到的數據主要來自瑞典和澳大利亞兩個獨立的研究中心。報告中最后的結論似乎忽略了瑞典作者大量的警告和提醒，同樣也忽視了澳大利亞人研究中的不足。首先，澳大利亞研究的側重點是呼吸檢驗，而不是降低血液酒精濃度的限制水平，在避免致命交通事故中所起到的作用。此外，這一研究開始于1976年，當時以酒為主的“液體午餐”非常普遍。另外，具體情況不同，澳大利亞的數據也有一定的變化。例如，反對醉駕母親協會的梅利提到，昆士蘭州致命交通事故的比例降低了18%，而它的鄰居新南威爾士州則僅僅降低了8%。
安大略湖社區理事的報道稱，由酒精引起致命交通事故的大部分司機都是慣犯，其本身血液酒精濃度都超過了0.15%。這意味著，經常開車的司機的血液酒精濃度是法定血液酒精濃度的兩倍，他們不是喝一兩杯紅酒的普通人。這使得反對醉駕母親協會所關心的內容顯得有點浪費時間，因為由酒精引起的致命交通事故呈下降趨勢。
加拿大安全理事會、加拿大汽車運輸管理者理事會及交通損傷研究機構也加入到了反對醉駕母親協會所提倡的這一運動中，盡管安大略湖社區理事會已經意識到降低血液酒精濃度意味著警方和法庭將增加工作量。但對于加拿大反對醉駕母親協會的梅利來說，計算方法非常簡單，即“如果降低血液酒精濃度的限制，不管降低多少，都是在挽救加拿大人的生命。”不幸的是，這種計算方法不能簡單相加。
51.C【精析】細節題。根據第一段第二句“‘Enough is Enough’advocatesdropping the Criminal Code’s blood alcohol concentration(BAC)limit from 0.08 to 0.05 percent…”可知，“適可而止”運動主要目的是為了降低血液酒精濃度限制，即限制司機對酒精的攝取，故選c。
52.D 【精析】細節題。根據第二段第一、二句“MADD selectively cites a report published in 2002 by Robert Mann...from two separate studies whose data was selected from Sweden and Australia.”可知，反對醉駕母親協會引用的是羅伯特·曼發表的內容，
而羅伯特·曼所獲得的數據信息來源于瑞典和澳大利亞兩個不同研究，由此可知，反對醉駕母親協會所引用的內容在其他兩項研究中提到過，故選D。
53.D 【精析】細節題。根據第二段第三句“The conclusions in Mann’Sreport seem to ignore the Swedish authors’numerouswarnings and cautions，as well as the limitations in theAustralianstudy.”可知，曼的報告之所以不可信是因為報告忽略了所引用研究中的不足，故選D。
54.B【精析】推理題。根據文中第三段內容可知，交通事故發生主要是因為開車司機血液酒精濃度含量超標，而不是因為他們偶爾喝了一兩杯紅酒，因此反對醉駕母親協會的擔心是多余的，由此可推知其倡導的運動有可能會毫無意義，故選B。
55.C 【精析】作者觀點題。根據全文作者對這場運動提出的一系列問題及文章最后一段作者表示梅利的計算方法不能簡單相加可知，作者對此事持有懷疑的態度，故選C。

一項最新研究顯示，有些詞產生的威力很大。倆如，網球以數字圖像的形式出現在四十位競爭實力相當的網球選手面前。每個球出現之前，選手都會看到或聽到諸如“好球”或“臭球”之類的評語。選手聽到負面評價時，發球反應明顯變慢。他們都是些訓練確素的專業運動員，一般不會自己造成失誤。
這是為什么呢?因為負面反饋信息降低了他們的自信心。如果心里想著成功，那你就會為了獲得威功付出巨大的努力并產生積極的動力。自信的人會鼓舞他人;機會似乎也經常光顧自信的人。他們對威功有著巨大的吸引力。
所以應該學習為自己加油鼓勁的重要性，讓自己的頭腦中時刻回蕩著積極的聲音。優秀運動員的成功很少僅僅歸功于天生的才能，他們成功的真正原因是準備得很充分。他們專注于自己所從事的事，如果有需要，他們愿意努力訓練，并且頭腦中時刻回蕩著積極的聲音。
如果你是自己的教練，那么最重要的一點就是要像任何一個外界建議者或者一個好的父母那樣告誡自己：練習，練習，再練習。避免和吸于你的能量，降低你的自信的人在一起，要和那些欣賞你的人待在一塊，并經常提醒自己這一點。悲觀的人會把你帶入一種消極情緒中，就像愛抱怨的人和愛批評別人的人一樣。如果有一種建立自信心的模式，那就是受傷后。主動回到比賽中，別管自己的傷口。
但是，這里也有一些重要的警告。恐懼可能會使得你精神萎靡，從而不能清楚地思考，以至于產生一些小小的失誤。如果你遭受了嚴重的損失，給自己點時間慢慢接受所遇到的挫折。不要否定挫折給自己所帶來的傷害或者急于解決問題。讓支持你的正面力量重新聚集到你身邊，并讓自己受其滋養。閑坐在那兒思考自己的損失是解決問題最糟糕的手段。
56.B【精析】細節題。根據第一段第三句“the reaction times of playershearing negative remarks were measurably slower.”可知，選手聽到負面評價會影響發揮，由此推知，接收到正面評價會有好的表現，故選B。
57.D【精析】推理題。根據第二段內容可知，如果心里想著自己能夠贏，就會不斷付出努力，產生積極奮斗的動力，最后也才更有可能成功，由此可推知，一個人如果想成功，首先要想象自己是個贏家，故選D。
58.A 【精析】細節題。根據第三段第一句中“pep talks”后面內容“keep the voice in yourhead positive”可知，既然是頭腦中回蕩著積極的聲音，那前面說的話肯定是為自己加油鼓勁的話，可知pep talks指的是鼓勵人的話，故選A。
59.C【精析】細節題。根據第四段第二句和第三句
“Avoidindividuals who suck your energy and diminishyour confidence.Hang out with the people who see you at your best，and remind you about it every SO often.”可知，要和那些鼓勵欣賞你的人在一塊，不要和那貶低你能力的人、讓自己產生不自信的人在一塊，由此推知，作者建議要和那些給你加油鼓勁的人在一塊，故選C。
60.D【精析】細節題。根據最后一段第三句和第四句“Ifyou suffer a terrible loss.give yourself time to absorb the blow.Don’t deny the hurt ortry to solve the problemimmediately.”可知，遇到挫折不要急著否定自己的傷痛，也不要立刻解決所遇到的問題，而是要給自己點時間，慢慢接受所遇到的挫折，故選D。

下面這段文字是5個人對于專題報道中提到的新藥的不同評論。
安·百斯特：
你專題報道中提到的新藥對威脅人類的多種疾病的治愈有令人振奮的前景。但是普通人如何支付的起這些現代神奇的藥品呢?一家制藥公司希望研發這些藥品所賺的錢“直接轉化為純利潤進入投資者的口袋中”。對我來說，唯一的問題是：我是用錢來買食物呢，付房租呢，還是用來買藥呢?
湯姆·瓦肯：
作為一個普通市民，我總是指責制藥公司把藥品的價格定得太高了，然而我發現你對新藥的報道動搖了我的立場。制藥公司說他們必須把藥品價格定的高一些才能有資金做研究，從而研發出更好的藥品。既然我知道有更新、更好的藥品，那么我也很樂意支付我的藥物治療費用，因為我意識到自己是為了更好的生活在進行投資。
羅伯特·卡姆：
我們都希望自己長命百歲，身體健康，但是通過吃藥將我們從自虐的生活方式中拯救出來僅僅掩蓋了，而沒有真正解決問題，并讓我們一年花數十億的錢來買藥。我們至少要找找原因，想想為什么數以百萬計的人過著對自已不利的生活——吸煙，酗酒，過勞，缺乏鍛煉.總之做一些對健康不利的事情。
約翰·巴格肖：
健康狀況不好付出的代價是慘重的，有時不僅僅是需要花錢的事兒了。提供最佳解決途徑、降低風險、減少需求、讓人們變得健康的方法就是預防。美國的慢性病有很多種。正是因為我們從來沒有找出原因，所以情況更為糟糕。美國人需要將這個問題提上議程討論直到獲得一個以預防為基礎的保健體系。
勞拉·伍茲：
盡管我為醫藥領域所取得的研究成功鼓掌祝賀，但同時我也意識到好事兒可能一下就變成壞事兒了。我患有心臟病，并且對新的治療有排斥反應，結果就是我住了很長時間醫院。我們應該記住，一種新藥被投入使用之前，各種禁忌都要被測試到。在關懷醫藥體系中，沒有什么能取代人的成分。
61.E【精析】主旨題。安·百斯特認為新藥能治愈威脅人類的多種疾病這個消息很令人振奮，但是同時對藥品高額的費用提出了自己的看法，這與E項“不管新藥效果多好，它的費用是人們首要的考慮因素”表示的意思相同。故選E。
62.G【精析】主旨題。湯姆·瓦肯從報道中了解到新藥之所以費用高是因為制藥公司需要資金進行更新的藥品研究，而買這些藥品就像是為自己高質量的生活投資一樣，因此花高價買藥也是可以接受的，這與G項“制藥公司藥價高是合理的”表示的意思相同，故選G。
63.D【精析】主旨題。羅伯特·卡姆認為身體不健康主要是自己不良的生活習慣導致的，如果改變了自己的生活方式，就不用花那么多錢去買藥了。這與D項“改變生活習慣比吃藥更有用”表示的意思相同，故選D。
64.A【精析】主旨題。約翰·巴格肖認為美國的慢性病有很多種，讓人們身體健康的有效途徑是建立以預防為基礎的保健體系，這與A項“預防在治療之前”表示的意思相同，故選A。
65.B【精析】主旨題。勞拉·伍茲根據自己對新藥產生排斥反應這一親身經歷強調用新藥之前，一定要測試各種禁忌，這與B項“新藥治療必須要了解其中禁忌”表示的意思相同，故選B。
