第十二篇The Enemy WithinAllergy has become more and more common over the last 30 years. Now one-third of us are affected by allergy at some point in our lives and half of these sufferers are children. In the UK, three million people suffer from asthma, and five per cent of children suffer from food allergy.Allergy is a reaction that occurs when the immune system has a strange and unnecessary reaction to a substance which is normally harmless, such as pollen or peanuts. _1_ To defend your body against an attacker, the immune system remembers these dangerous micro-organisms and attacks them if it meets them again. This work is done by antibodies. The immune system in allergy sufferers makes antibodies against harmless substances, because it mistakenly believes them to be dangerous.An allergic reaction may not happen the first time a sufferer meets an allergen (the substance causing the reaction, such as pollen, milk or strawberries). Sometimes people can eat nuts for years and then suddenly become allergic to them. What has happened is that the immune system has now decided the substance is dangerous and has made an allergy antibody. This antibody then attaches itself to cells, which contain histamine. _2_ As they do that, the surface of the cells is broken, and histamine is released. The histamine and other chemicals inflame the tissues. This leads to the symptoms of allergy, such as swelling, rashes, sneezing, sore eyes and breathlessness. Anaphylaxis is the most severe allergic reaction of all and is most often triggered by wasp or bee stings or peanuts. This must be treated immediately._3_ Some people are born with the ability to make lots of allergy antibodies, and they are more likely to develop allergies and allergic disorders such as hay fever and asthma._4_ We eat more processed foods, with a wide range of additives and colourings; more and more people have central heating and double glazing, making our houses warmer and less draughty-an ideal environment to breed the house dust mite.There may also be a link between allergies and antibiotics. At one time our immune systems were kept busy fighting off disease and trying to win the battle for health, but antibiotics have reduced the amount of work our immune systems have to do. Now experts think they may direct spare energy to harmless substances such as strawberries. _5_A good deal of research is being devoted to finding a cure for allergies. Sufferers may be given medicine to control symptoms, and they may also be offered tests to find out what substances trigger an allergic reaction so that they can avoid contact with these in future.詞匯：allergyn.過(guò)敏，過(guò)敏癥sufferern.患者，受害者asthman.哮喘substancen.物質(zhì)pollenn.花粉micro-organismn.微生物antibodiesn.antibody的復(fù)數(shù)形式，意為抗體allergenn.過(guò)敏源nutn.堅(jiān)果histaminen.組織胺，組胺tissuen.人體組織symptomn.病癥，征兆rashn.皰疹sneezingn.打噴嚏breathlessnessn.呼吸急促，氣喘吁吁anaphylaxisn.全身性過(guò)敏反應(yīng)，過(guò)敏反應(yīng)waspn.黃蜂stingn.蟄，咬hayfevern.枯草熱，花粉病additivesn.添加劑，食品添加劑curen.治療，解藥注釋?zhuān)?suffer from.忍受的折磨2be devoted to sth. .全身心投入于練習(xí)：AThe immune system is there to protect the body against outside attackers, including viruses, bacteria and parasites.BIn other words our immune systems have become over-sensitive.CAllergies run in families.DInternational differences have been associated with the number of individuals within a population have allergy.EWhen the antibodies meet the allergen the next time, they attempt to destroy it.FExperts believe more people have developed allergies because of changes in our lifestyle which have exposed us to more allergens.答案與題解：1A該是對(duì)機(jī)體免疫系統(tǒng)功能的介紹，而文中對(duì)免疫系統(tǒng)的首次提及是在該選項(xiàng)的上一句話，即描述過(guò)敏反應(yīng)是免疫系統(tǒng)的活動(dòng)，該選項(xiàng)故而可被視為是對(duì)上一句話的補(bǔ)充與說(shuō)明。2E本題做題線索有兩點(diǎn)，首先是上下文，本段前幾句都是對(duì)抗體的描述與介紹，故與選項(xiàng)E主題相符，同時(shí)第二個(gè)做題點(diǎn)為邏輯順序詞，本段的第一句話中提到了An allergic reaction may not happen the first time a sufferer meets an allergen，而該選項(xiàng)中又有了the next time，這兩個(gè)邏輯順序詞也構(gòu)成了解題線索。3C該選項(xiàng)在文章的第四段，講的是過(guò)敏反應(yīng)在特殊人群中的反應(yīng)，選項(xiàng)C的意思為“過(guò)敏反應(yīng)是具有遺傳性的”，與該段后一句some people are born with the ability.相對(duì)應(yīng)。4F文章第五段主要講的是能導(dǎo)致過(guò)敏反應(yīng)的兩個(gè)例子，缺少中心句，而選項(xiàng)C恰好能對(duì)這兩個(gè)例子進(jìn)行概括說(shuō)明，故答案為選項(xiàng)C。5B該選項(xiàng)為概括總結(jié)項(xiàng)，是對(duì)前文說(shuō)的內(nèi)容進(jìn)行總結(jié)，該段的前面部分提及的是抗生素與過(guò)敏反應(yīng)之間的關(guān)系，即其對(duì)于人體免疫系統(tǒng)的影響，而該選項(xiàng)則是一個(gè)結(jié)果性的描述，即免疫系統(tǒng)變得過(guò)于敏感了，其可對(duì)前文中抗生素的作用進(jìn)行總結(jié)說(shuō)明。過(guò)敏在過(guò)去30年中，已經(jīng)變得越來(lái)越普及。目前，在我們生活的不同時(shí)期內(nèi)，有1/3的人發(fā)生過(guò)過(guò)敏，其中半數(shù)為兒童。在英國(guó)，有300萬(wàn)人受哮喘病的折磨，并有5%的兒童對(duì)食物過(guò)敏。過(guò)敏指的是免疫系統(tǒng)對(duì)于通常無(wú)害的物質(zhì)（如花粉、花生）所做出的奇怪且不必要的反應(yīng)。免疫系統(tǒng)能夠保護(hù)我們的身體免受外界的侵襲，這些物質(zhì)包括病毒、細(xì)菌以及寄生蟲(chóng)。為了保護(hù)人體免受外界的侵襲，免疫系統(tǒng)會(huì)記憶這些危險(xiǎn)的微生物，并在再次遭遇它們時(shí)對(duì)其進(jìn)行攻擊。這一功能由抗體完成。過(guò)敏患者的免疫系統(tǒng)會(huì)對(duì)無(wú)害物質(zhì)產(chǎn)生抗體，錯(cuò)誤地認(rèn)定這些物質(zhì)是危險(xiǎn)的。過(guò)敏反應(yīng)在患者首次接觸過(guò)敏源（造成過(guò)敏反應(yīng)的物質(zhì)，如花粉、牛奶、草莓）時(shí)可能不會(huì)發(fā)生。有時(shí)，人們會(huì)在多年正常食用堅(jiān)果后，突然變得對(duì)其過(guò)敏，其免疫系統(tǒng)在這一過(guò)程中認(rèn)定該類(lèi)物質(zhì)為危險(xiǎn)物質(zhì)并針對(duì)其產(chǎn)生了免疫抗體。這種抗體將其自身與人體中含有組織胺的細(xì)胞相連接。當(dāng)再次遭遇這類(lèi)過(guò)敏源時(shí)，這一抗體就會(huì)試圖摧毀它。當(dāng)抗體發(fā)揮功效時(shí)，與其連接的細(xì)胞的外表會(huì)破裂并釋放出組胺。組胺及其他化學(xué)物質(zhì)使人體組織發(fā)炎。過(guò)敏癥狀就會(huì)發(fā)生，如浮腫、皰疹、打噴嚏、眼痛及呼吸急促。全身性過(guò)敏反應(yīng)是最嚴(yán)重的過(guò)敏性反應(yīng)，其通常由黃蜂或蜜蜂叮咬或食用花生所致。這類(lèi)過(guò)敏反應(yīng)必須立刻就醫(yī)。過(guò)敏癥會(huì)在家庭成員中傳播。有些人天生能產(chǎn)生多種過(guò)敏抗體，因此他們更容易發(fā)生過(guò)敏或者過(guò)敏性失調(diào)，如花粉病及哮喘。專(zhuān)家認(rèn)為，會(huì)有越來(lái)越多的人出現(xiàn)過(guò)敏反應(yīng)，因?yàn)槲覀兩罘绞降淖兓刮覀儽┞对谠絹?lái)越多的過(guò)敏源之中。我們食用越來(lái)越多經(jīng)過(guò)精加工的食物，這些食物添加了多種添加劑與色素；越來(lái)越多的人采用了集中供暖系統(tǒng)并使用雙層玻璃，這使得我們的房子變得更加溫暖且更加密閉，為塵螨提供了完美的繁育環(huán)境。過(guò)敏還可能與抗生素有關(guān)。我們?cè)欢纫揽孔陨淼拿庖呦到y(tǒng)與疾病抗?fàn)巵?lái)保護(hù)我們的健康，但抗生素減少了免疫系統(tǒng)本該做的工作。如今，專(zhuān)家們認(rèn)為，免疫系統(tǒng)會(huì)把多余的能量用到一些無(wú)害物質(zhì)上，如草莓。換句話說(shuō)， 我們的免疫系統(tǒng)變得過(guò)于敏感了。人們正在為尋找治療過(guò)敏的方法展開(kāi)大量研究?；颊呖梢酝ㄟ^(guò)藥物治療來(lái)抑制癥狀，還可以通過(guò)各種檢查來(lái)確定引起過(guò)敏反應(yīng)的物質(zhì)，這樣他們就可以在將來(lái)避免與這類(lèi)物質(zhì)接觸。第十四篇Primer on SmellIn addition to bringing out1 the flavor of food, what does the sense of smell do for us?Smell “gives us information about place, about where we are,” says Randall Reed, a Johns Hopkins University professor whose specialty is the sense of smell. _1_ “Whether we realize it or not, we collect a lot of information about who is around us based on smell,” says Reed.Even at a distance, odors can warn us of2 trouble spoiled food, leaking gas, or fire. “Its a great alert,” offers Donald Leopold, a doctor at Johns Hopkins. For example, if something in the oven is burning, everyone in the house knows it.With just a simple scent, smell can also evoke very intense emotion. Lets say, for example, that the smell is purple petunias. _2_ Now lets imagine that your mother died when you were three, and she used to have a flower garden. You wouldnt need to identify the smell or to have conscious memories of your mother or her garden. You would feel sad as soon as you smelled that spicy odor.Compared with3 animals, how well do people detect smelts?That depends on what you mean by “how well”. We are low on receptor cells ： current estimates say that humans have roughly five million smell-receptor cells, about as many as a mouse. _3_Reed says that, across species, there is a relatively good correlation between the number of receptor cells and how strong the sense of smell is. “You can hardly find the olfactory bulb in a human brain its a pea-sized object. In a mouse, its a little bigger. Its bean-sized in a rat, about the size of your little finger in a rabbit, and the size of your thumb in a bloodhound.”Does that mean that our sense of smell is not very acute?Not exactly. While we may not have the olfactory range of other creatures, the receptors we do have are as sensitive as those of any animal. _4_ A trained “nose”, such as that of a professional in the perfume business, can name and distinguish about 10,000 odors. Reed says that a perfume expert can sniff a modem scent that has a hundred different odorants in it, go into the lab, and list the ingredients. “In a modest amount of time, he comes back with what to you or me would smell like a perfect imitation of that perfume. Its amazing.”What happens to4 our sense of smell as we age?Many people continue to have good olfactory function as they get older. _5_ Leopold says that smell is generally highest in childhood, stays the same from the teens through the 50s, and drops starting at about 60 for women and 65 for men. “The average 80-year-old is only able to smell things half as well as the average 20-year-old,” says Leopold.詞匯：scent /sent/ n. 氣味，香味petunia /ptju:ni/ n. 喇叭花olfactory /lfkt()ri/ adj. 嗔覺(jué)的，味道的sniff /snif/ v. 嗅，聞，用力吸注釋?zhuān)?. bring out：使顯出，使變得明顯2. warn of：發(fā)出關(guān)于的警告。warn sb. of sth.：警告某人某事3. compare with：與相比4. happen to：發(fā)生于，發(fā)生在練習(xí)：A These flowers have a rich spiciness that no other petunia has.B Odors, or smells, can warn us about trouble.C Thats not the rule, however.D And smell tells us about people.E We can also think, and we make conscious (and successful) efforts to tell the difference between one smell and another.F A rat has some 10 million, a rabbit 20 million, and a bloodhound 100 million.答案與題解：1. D根據(jù)后文提到的“我們能夠根據(jù)氣味收集到有關(guān)人的很多信息”可以推斷此處答案是D選項(xiàng)。2. A前文提到以紫喇叭花的香味舉例，選項(xiàng)中只有A選項(xiàng)提到了喇叭花。3. F前文提到人類(lèi)和小鼠的嗅覺(jué)受體細(xì)胞數(shù)量，可以推斷此處應(yīng)介紹其他物種的嗅覺(jué)受體細(xì)胞數(shù)量。4. E后文都在介紹人類(lèi)可以區(qū)分味道的不同，所以此處E選項(xiàng)最符合原文意思。5. C后文介紹了不是每個(gè)人都隨著年齡的增長(zhǎng)嗅覺(jué)能力不發(fā)生變化，所以此處C選項(xiàng)最符合原文。參考譯文第十四篇 嗅覺(jué)入門(mén)嗅覺(jué)除了能讓我們感受到食物的氣味外，還能做什么？美國(guó)約翰霍普金斯大學(xué)研究嗅覺(jué)的專(zhuān)家Randall Reed教授指出，氣味能提供給我們關(guān)于位置，關(guān)于我們?cè)谀膬海约坝嘘P(guān)人的信息。“無(wú)論我們是否意識(shí)到，我們能根據(jù)氣味收集到許多關(guān)于誰(shuí)在我們身邊的信息，”Reed講道。即使還隔著一段距離，氣味就能提醒我們注意很多麻煩：變質(zhì)的食物，煤氣泄漏，或是火災(zāi)?！八且粋€(gè)很好的警告，”約翰霍普金斯大學(xué)的醫(yī)生Donald Leopold說(shuō)道。比方說(shuō)，烤箱中有東西燒焦了，屋內(nèi)的每個(gè)人都會(huì)知道。僅僅是簡(jiǎn)單的氣味，嗅覺(jué)就會(huì)引起強(qiáng)烈的情感。比如說(shuō)那種氣味就是紫喇叭花。它的氣味中有一種其他喇叭花沒(méi)有的香味?，F(xiàn)在我們想象一下，你的母親在你3歲時(shí)就去世了，她曾經(jīng)擁有一座花園。你不必去辨認(rèn)那種氣味或者有意識(shí)地回憶起你的母親或者她的花園，只要是你聞到那種紫喇叭花的香味，你就會(huì)感到傷感。與動(dòng)物相比，人類(lèi)感知?dú)馕兜哪芰τ卸鄰?qiáng)？那要取決于你所謂的“多強(qiáng)”是什么意思。我們?nèi)祟?lèi)的受體細(xì)胞很少：目前估計(jì)人類(lèi)有大概500萬(wàn)個(gè)嗅覺(jué)受體細(xì)胞，差不多和一只小鼠的一樣多。一只大鼠大約有1 000萬(wàn)個(gè)，一只兔子有2 000萬(wàn)個(gè)，一只尋血犬有1億個(gè)。Reed談到，在不同的物種中，受體細(xì)胞的數(shù)量和嗅覺(jué)的強(qiáng)弱大體是正相關(guān)的?！叭说拇竽X中是幾乎找不到嗅球的，它像豌豆般大小。小鼠的腦中，嗅球大一點(diǎn)。大鼠的腦中，嗅球有蠶豆那么大，兔子腦中的有你的小手指那么大，而尋血犬腦中的有拇指那么大?！边@是不是就意味著我們的嗅覺(jué)不夠敏銳呢？不完全是。盡管我們的嗅覺(jué)范圍可能沒(méi)有其他生物的那么廣，但是我們已有的受體細(xì)胞和其他動(dòng)物的一樣敏感。我們也可以認(rèn)為，我們?cè)谟幸猓ú⑶页晒Φ嘏^(qū)別不同的氣味。受過(guò)培訓(xùn)的鼻子，比如研究香水的專(zhuān)家的鼻子就能夠區(qū)分1萬(wàn)種氣味并說(shuō)出其名字。Reed說(shuō)，一個(gè)香水專(zhuān)家可以在聞完一種含有100種不同香料的現(xiàn)代香水后，走進(jìn)實(shí)驗(yàn)室，列出這些成分?！耙欢螘r(shí)間過(guò)后，他調(diào)制出來(lái)的氣味對(duì)于你我來(lái)說(shuō)都是那種香水氣味的完美復(fù)制，太不可思議了。”隨著年齡的增長(zhǎng)，我們的嗅覺(jué)會(huì)發(fā)生什么變化？許多人年齡增大時(shí)還會(huì)有很好的嗅覺(jué)能力。但并不都是這樣。指出，一個(gè)人的嗅覺(jué)在兒童時(shí)最強(qiáng)，在青少年時(shí)期一直到50多歲都保持不變，女人通常從60歲、男人從65歲開(kāi)始下降?！巴ǔ?lái)說(shuō)，80歲的人能聞到的東西是20歲的人能聞到的一半，”Leopold說(shuō)道。第十一篇LeukemiaLeukemia is the most common type of cancer kids get, but it is still very rare. Leukemia involves the blood and blood-forming organs, such as the bone marrow._1_A kid with leukemia produces lots of abnormal white blood cells in the bone marrow. Usually, white blood cells fight infection, but the white blood cells in a person with leukemia dont work the way theyre supposed to. _2_The abnormal white blood cells multiply out of control1, filling the bone marrow and making it hard for enough normal, infection-fighting white blood cells to form. Other blood cells such as red blood cells (that carry oxygen in the blood to the bodys tissues) and platelets (that allow blood to clot) are also crowded out2 by the white blood cells of leukemia. These cancer cells may also move to other parts of the body, including the bloodstream, where they continue to multiply and build up3.Although leukemia can make kids sick, most of the time it is treatable, and kids get better. Almost all leukemia patients are treated with chemotherapy, which means using anti-cancer drugs._3_Chemotherapy quickly goes to work, traveling through the blood to the bone marrow. There, the drugs can attack the cancer cells. After several weeks of chemotherapy, many kids begin to feel better.Some children with leukemia will also have to have radiation therapy, too. _4_If the cancer isnt getting better from using the usual amounts of chemotherapy and radiation, then kid with leukemia will probably need more treatment with higher doses of chemotherapy and radiation to finally kill the cancer cells. But this heavy-duty treatment will also harm the normal cells in the kids bone marrow too, and the bone marrow will no longer be able to produce normal blood cells. So, doctors will then give a kid or anyone else with bone marrow that is no longer working normal bone marrow tissue from someone else who is healthy. _5_詞匯：leukemia 白血病 marrow 髓 innermost 最內(nèi)的，最深處的abnormal 反常的，變態(tài)的 infection 感染 multiply .增加，繁殖platelet 血小板 clot (血等)凝結(jié)成塊 bloodstream 血流chemotherapy 化學(xué)療法 catheter 導(dǎo)管 insert 插入，嵌入invisible 看不見(jiàn)的，無(wú)形的 cancerous 生癌的;患癌癥的heavy-duty . 重型的;大劑量的 transplant 移植注釋?zhuān)?.out of control：失去控制;不受控制2.are also crowded out：也被排擠出去3.build up：逐漸積聚;集結(jié)練習(xí)：A.

But glucose cant be used by the body on its ownit needs a hormone called insulin to bring it into the cells of the body.Most people get the insulin they need from the pancreas, a large organ near the stomach. The pancreas makes insulin; insulin brings glucose into the cells; and the body gets the energy it needs. When a person has insulin-dependent diabetes, its because the pancreas is not making insulin. So someone could be eating lots of food and getting all the glucose he needs, but without insulin, there is no way for the body to use the glucose for energy. _2_You may have heard older people talk about having diabetes, maybe people of your grandparents age. Usually, this is a different kind of diabetes called non-insulin-dependent diabetes. It can also be called Type 2 diabetes, or adult-onset diabetes. _3_When a kid is diagnosed with juvenile (insulin-dependent) diabetes, he will have that type of diabetes for his whole life. It wont ever change to non-insulin-dependent diabetes when he gets older.Scientists now think that a person who has juvenile diabetes was born with a certain gene or genes that made the person more likely to get the illness. _4_ Many scientists believe that along with having certain genes, something else outside the persons body, like a viral infection, is necessary to set the diabetes in motion by affecting the cells in the pancreas that make insulin.But the person must have the gene (or genes) for diabetes to start out with this means you cant get diabetes just from catching a flu, virus, or cold. And this type of diabetes isnt caused by eating too many sugary foods, either. Diabetes can take a long time to develop in a persons body sometimes months or years. Another important thing to remember is that diabetes is not contagious. _5_詞匯：viral 病毒(性)的;病毒引起的 infection 感染sugary 糖的;含糖的;甜的;太甜的 contagious 觸染的;傳染的insulin 胰島素 diabetes 糖尿病 glucose 葡萄糖hormone 激素，荷爾蒙 pancreas 膜(腺)onset 開(kāi)始 juvenile 少年的注釋?zhuān)?.insulin-dependent diabetes：胰島素依賴(lài)型糖尿病2.on its own：獨(dú)立地，靠自己的力量3.non-insulin-dependent diabetes：非胰島素依賴(lài)型糖尿病4.adult-onset diabetes：成人型糖尿病5.juvenile (insulin-dependent) diabetes：少年型(胰島素依賴(lài)型)糖尿病6.to set the diabetes in motion by affecting the cells in the pancreas that make insulin：通過(guò)對(duì)胰腺中生成胰島素的細(xì)胞的影響而導(dǎo)致糖尿病的發(fā)作練習(xí)：AGenes are something that you inherit from your parents, and they are in your body even before youre born.BThis sugar-fuel is called glucose.CIt may be possible to beat insulin resistance through lifestyle changes.DYou cant catch diabetes from people who have it, no matter how close you sit to them or if you kiss them.EThe glucose cant get into the cells of the body without insulin.FWhen a person has this kind of diabetes, the pancreas usually can still make insulin, but the persons body needs more than the pancreas can make.答案與題解：1.B文章第一句講，人進(jìn)食后，身體便會(huì)從食物中獲得糖并將其轉(zhuǎn)化成燃料。接下來(lái)應(yīng)首選對(duì)這種糖燃料加以解釋的句子。2.E前兩句講到，患胰島素依賴(lài)型糖尿病的病人，其胰腺不能生成胰島素，因此，盡管某人進(jìn)食大量食物并獲取所需的全部葡萄糖，但沒(méi)有胰島素，身體就無(wú)法利用這些葡萄糖獲取能量。也就是說(shuō)，沒(méi)有胰島素，葡萄糖就不能進(jìn)入身體的細(xì)胞內(nèi)。3.F此段的前幾句主要講非胰島素依賴(lài)型糖尿病，并指出它不同于胰島素依賴(lài)型糖尿病。二者之間的主要區(qū)別是什么呢?回答這個(gè)問(wèn)題的句子應(yīng)當(dāng)首選。4.A前一句講，科學(xué)家們現(xiàn)在認(rèn)為，患少年型糖尿病的人出生時(shí)就具有某個(gè)或者某些使其易患此病的基因。基因是什么呢?回答這問(wèn)題的句子當(dāng)然應(yīng)該首選A。5.D前一句說(shuō)明了糖尿病不具有觸染性，接下來(lái)應(yīng)當(dāng)是對(duì)該句加以闡釋的句子。譯文：什么是胰島素依賴(lài)型糖尿病?你在吃東西時(shí)，你的身體會(huì)從食物中獲得糖并將其轉(zhuǎn)化成燃料。這種糖燃料就是葡萄糖。你的身體通過(guò)葡糖糖產(chǎn)生能量，這使你能夠做從呼吸道打電子游戲的任何事情，但葡糖糖不能直接被身體利用它需要通過(guò)一種叫胰島素的荷爾蒙來(lái)將其運(yùn)送到身體的細(xì)胞中。大多數(shù)人通過(guò)胃旁邊的一個(gè)大型器官胰中獲得所需的胰島素。胰腺生成胰島素;胰島素把葡糖糖運(yùn)送至細(xì)胞后肌體獲得其所需能量。胰島素依賴(lài)型糖尿病人的胰腺不能生成胰島素，因此，盡管他大量進(jìn)食并獲取所需的全部葡糖糖，但沒(méi)有胰島素，身體就無(wú)法利用這些葡糖糖獲取能量。沒(méi)有胰島素，葡糖糖就不能進(jìn)入身體的細(xì)胞內(nèi)。你可以聽(tīng)到過(guò)老人談?wù)撎悄虿?，可能有些老人與你的祖父母年齡相仿。一般說(shuō)來(lái)，這是一種不同類(lèi)型的糖尿病，叫作非胰島素依賴(lài)型糖尿病，也叫型糖尿病或成人型糖尿病?；歼@種糖尿病的人，其胰腺仍能生成胰島素，但它滿(mǎn)足不了身體對(duì)胰島素的需求量。當(dāng)一個(gè)孩子被診斷為少年型(胰島素依賴(lài)型)糖尿病時(shí)，他將終生都患該種糖尿病，而且不會(huì)隨著年齡增長(zhǎng)而變成非胰島素依賴(lài)型糖尿病?？茖W(xué)家們現(xiàn)在認(rèn)為患青少年型糖尿病的人出生時(shí)就具有某個(gè)或某些使其易患此病的基因?；蚴菑母改改抢镞z傳得來(lái)的，它在人出生前就存在于其體內(nèi)。許多科學(xué)家還認(rèn)為，除了有某種基因外，一些人體外部的原因，比
