    You probably already know that a viselike pressure in the chest is the most common physical sign of a heart attack. You may even be aware that the body sometimes “has” the pain of a heart attack, sending to the neck, jaw or arms. But do you know the second, third or fourth most common sign of a heart attack? You should. According to a study in Journal of the American Medical Association (JAMA), recognizing the less common signs of a heart attack could save your life or that of someone you love.
    Speed makes a difference. Heartattack victims who dont experience chest pain typically put off going to the hospital—by an average of two hours, the JAMA study found. When these patients finally show up at the emergency room, it often takes doctors longer to make the right diagnosis. Their heart isnt getting potentially lifesaving treatment with clotbusting drugs, or emergency angioplasty. 1) These delays help explain why a heartattack patient who doesnt experience chest pains is twice as likely to die at the hospital as someone who does.
    2) By studying a computerized data of more than 430,000 people who suffered heart attacks across the U. S., it was determined that there are six major risk factors that increase the chances that any heart attack you suffer will be atypical. These six risk factors include: having a weak heart (from congestive heart disease), diabetes or a history of stroke ; being 65 or older, female or from a minority group. The increased risk is cumulative: If a 75yearold black woman has a heart attack, her chances of experiencing chest pain are less than 50%.
    3) Apparently diabetics feel less pain because of nerve damage caused by their condition, but no one knows why women or the elderly are more likely to suffer painless heart attacks.
    So what, besides chest pain, should you watch for? Probably the next biggest tipoff is extreme shortness of breath. Indeed, many cardiologists consider difficulty breathing to be as good an indicator of a possible heart attack as chest pain. Other less specific signs include nausea, profuse sweating and fainting. Some heartattack victims describe a sudden, overwhelming sense of doom or feel pain under their scapula.
    Be particularly suspicious of any “heartburn” that gets worse if you walk around or otherwise exert yourself physically. Dont try to drive yourself to the hospital. Call an ambulance. Then, if you think of it, chew on an aspirin; 325 mg is the recommended dose, and chewing gets the drug into the bloodstream faster. A single tablet can stave off some of the damage. Above all, dont tell yourself, “I cant be having a heart attack, I’m not feeling any chest pains. ” Let a doctor make the final call.

    [C] A 67yearold black woman who has diabetes since her birth.
    [D] A 40yearold sportsman who suffers arms pain very often.
    4 We can infer from the text that
    [A] diabetics will feel less chest pain because their nerves are hurt by their heart attack.
    [B] people are clear about why ladies or the elderly suffer less chest pain in a heart attack.

    難句突破
    1These delays help explain why a heartattack patient who doesn’t experience chest pains is twice as likely to die at the hospital as someone who does.
    【解析】本句話的主干是“These delays help explain...”。why引導(dǎo)的是賓語從句,其中的第一個who引導(dǎo)的定語從句修飾people,as ... as引導(dǎo)的是比較狀語從句,第二個who引導(dǎo)的定語從句修飾someone。
    2.By studying a computerized data of more than 430,000 people who suffered heart attacks across the U. S., it was determined that there are six major risk factors that increase the chances that any heart attack you suffer will be atypical.
    【解析】本句話的主干是“it was determined that...”。By studying...短語作方式狀語,其中的who引導(dǎo)的定語從句修飾people;it是形式主語,真正的主語是后面的第一個that引導(dǎo)的從句,第二個that引導(dǎo)的定語從句修飾factors,第三個that引導(dǎo)的定語從句修飾chances,其中的you suffer是一個省略了引導(dǎo)詞的定語從句,修飾heart attack。atypical應(yīng)譯成“非典型的”。
    3.Apparently diabetics feel less pain because of nerve damage caused by their condition, but no one knows why women or the elderly are more likely to suffer painless heart attacks.
    【解析】本句話的主干是“no one knows why...”。but前面的句子表示讓步,其中的caused by their condition修飾damage;why引導(dǎo)的是賓語從句。diabetic應(yīng)譯成“糖尿病患者”。
    試題解析
    1 根據(jù)第一段,心臟病發(fā)作的常見征兆不包括
    [A] 胸部的巨大壓迫感。
    [B] 一定的胸部疼痛。
    [C] 嚴(yán)重的頭疼。
    [D] 擴(kuò)展的脖子疼痛。【C】
    【解析】細(xì)節(jié)題。題干中的“the common signs of a heart attack”出自文章第一段第一句話中,表明本題與第一段有關(guān)。第一段提到,胸部有巨大的壓迫感是心臟病發(fā)作的最常見身體征兆,有時,心臟病發(fā)作導(dǎo)致的疼痛感會傳到脖子、下巴或胳膊。這說明,A、B和D是心臟病發(fā)作的常見征兆。只有C沒有提到,為正確答案。
    2 “Speed makes a difference”(第二段)是什么意思?
    [A] 匆忙可能有助于區(qū)別心臟病和其他疾病。
    [B] 如果患了心臟病,速度可能有助于挽救患者的生命。
    [C] 醫(yī)生應(yīng)該快速做出正確的診斷。
    [D] 患者應(yīng)該采用不同的速度去醫(yī)院?!綛】
    【解析】詞義題。第一段最后指出,知道心臟病發(fā)作的不太常見征兆可能挽救你自己的生命,或者你關(guān)愛的某個人的生命,第二段接著提到了該句話,隨后提到研究發(fā)現(xiàn),指出,那些沒有感受到胸部疼痛的心臟病患者通常延遲去醫(yī)院,當(dāng)這些患者出現(xiàn)在急診室時,醫(yī)生通常要花更長的時間做出正確診斷,結(jié)果是他們的心臟得不到可能挽救生命的治療。這說明,該句話表示,時間非常重要。B與此意符合,為正確答案。A、C和D都是誤解了該句話的意思。
    3 如果患了心臟病,下面哪種人會感受到最小的胸部疼痛?
    [A] 一個有5年中風(fēng)史的67歲男子。
    [B] 一個經(jīng)常出汗和昏厥的30歲女士。
    [C] 一個自出生以來就患糖尿病的67歲黑人女性。
    [D] 一個經(jīng)常胳膊疼痛的40歲男運(yùn)動員。【C】
    【解析】細(xì)節(jié)題。第三段提到,如果一位75歲的黑人女性心臟病發(fā)作,那么她感受到胸部疼痛的可能性不到50%,第四段接著指出,糖尿病患者感受到的疼痛更少,但沒有人知道為什么女性或老年人更可能患沒有疼痛感的心臟病。這說明,糖尿病患者感受到的疼痛最少。C與此意符合,為正確答案。A是導(dǎo)致增加所患的心臟病是非典型心臟病可能性的主要因素之一,與題目的要求不符;B是患心臟病不太具體的征兆之一,與題目的要求不符;D屬于無中生有。
    4 根據(jù)本文,我們可以推知,
    [A]糖尿病患者會覺得胸部不太疼痛,因?yàn)樾呐K病損害了他們的神經(jīng)。
    [B]對于為什么女性或老年人患心臟病時覺得胸部不太疼痛,人們很清楚。
    [C] 如果患了心臟病,應(yīng)該認(rèn)真對待許多常見的征兆。
    [D]呼吸異常短促是心臟病可能發(fā)作的征兆,就像胸部感到疼痛一樣?!綜】
    【解析】推論題。前面的段落介紹了心臟病發(fā)作的常見和不常見征兆,最后一段指出,最重要的是,不要告訴自己患的不是心臟病,因?yàn)闆]有感到胸部疼痛,應(yīng)該讓醫(yī)生做最后的診斷。由此可知,在你患有心臟病時,應(yīng)該關(guān)注常見和不常見征兆。C與此意符合,為正確答案。A和B是針對第四段設(shè)置的干擾項(xiàng),與文意不符合;D是文中明確指出的,不必推論就可知結(jié)果,所以不對。
    5 如果某人患了心臟病,他可以采取下面哪項(xiàng)措施?
    [A] 用水服阿斯匹林。
    [B] 盡量自己開車去醫(yī)院。
    [C] 使自己樂觀一點(diǎn)。
    [D] 認(rèn)真對待,叫救護(hù)車。【D】
    【解析】細(xì)節(jié)題。最后一段介紹了心臟病患者應(yīng)該采取的措施——不要試圖自已開車去醫(yī)院,應(yīng)該叫救護(hù)車,應(yīng)該嚼一片阿斯匹林,最重要的是,不要告訴自己“我患的不是心臟病,因?yàn)槲覜]有感到胸部疼痛”,應(yīng)該讓醫(yī)生做最后的診斷。只有D與此意符合,為正確答案。A是針對該段第三句話設(shè)置的干擾項(xiàng),文中說的是“嚼一片阿斯匹林”,不是用水服,所以不對;B明顯與該段第二句話的意思不符;C屬于無中生有。
    全文譯文
    你可能已經(jīng)知道,胸部有巨大的壓迫感是心臟病發(fā)作的最常見身體征兆。你甚至可能知道,身體有時“有”心臟病發(fā)作導(dǎo)致的疼痛感,這種疼痛會傳到脖子、下巴或胳膊。但是,你知道心臟病發(fā)作的第二種、第三種或者第四種常見征兆嗎?你應(yīng)該知道。根據(jù)《美國醫(yī)學(xué)協(xié)會雜志》的一項(xiàng)研究,知道心臟病發(fā)作的不太常見征兆可能挽救你自己的生命,或者你關(guān)愛的某個人的生命。
    速度很重要?!睹绹t(yī)學(xué)協(xié)會雜志》的研究發(fā)現(xiàn),那些沒有感受到胸部疼痛的心臟病患者通常延遲去醫(yī)院——平均起來為兩個小時。當(dāng)這些患者最后出現(xiàn)在急診室時,醫(yī)生通常要花更長的時間做出正確診斷。他們的心臟得不到可能挽救生命的治療——血液凝塊疏通藥物,或者緊急血管重建術(shù)。1)這些延誤幫助解釋了為什么沒有感受到胸部疼痛的心臟病患者在醫(yī)院死亡的可能性比那些感受到疼痛的患者大一倍的原因。
    2)通過研究全美43萬名心臟病患者的計(jì)算機(jī)數(shù)據(jù),研究人員確定,有六種主要的危險因素會增加你所患的心臟病是非典型心臟病的可能性。這六種主要的危險因素包括——有脆弱的心臟(源于充血性心臟病)、糖尿病或者中風(fēng)史;年齡為65歲或者更老,患者是女性,或者患者來自少數(shù)民族群體。增加的危險是累積起來的——如果一位75歲的黑人女性心臟病發(fā)作,那么她感受到胸部疼痛的可能性不到50%。
    3)很顯然,糖尿病患者感受到的疼痛更少,這是因?yàn)樗麄兊牟∏樗鶎?dǎo)致的神經(jīng)破壞,但是,沒有人知道為什么女性或老年人更可能患沒有疼痛感的心臟病。
    因此,除了胸部疼痛之外,你還應(yīng)該注意什么呢?可能下一個最明顯的跡象就是呼吸異常短促。實(shí)際上,許多心臟病專家認(rèn)為,呼吸困難可能是心臟病發(fā)作的征兆,就像胸部感到疼痛一樣。其他不太具體的征兆包括惡心、大汗淋漓以及昏厥。有些心臟病患者聲稱,他們會突然有一種強(qiáng)烈的末日感,或者覺得肩胛骨下部疼痛。
    如果你出去散步,或者努力鍛煉身體,那么你應(yīng)該特別留意越來越厲害的“心痛”。不要試圖自已開車去醫(yī)院。應(yīng)該叫救護(hù)車。然后,如果你想起來了,就應(yīng)該嚼一片阿斯匹林,建議的劑量是325毫克。咀嚼可以使藥物更迅速地進(jìn)入血液。一片阿斯匹林就可以抵擋一定的損害。最重要的是,不要告訴自己“我患的不是心臟病,因?yàn)槲覜]有感到胸部疼痛。”應(yīng)該讓醫(yī)生做最后的診斷
