也相应变化。这是医学英语中的高频词汇，其他选项均为错误变形。类似的希腊词源复数变化还包括"prognosis-prognoses"、"parenchyma-parenchyma"等，需特别注意记忆。42.【参考答案】B【解析】"contraindication"由前缀"contra-"（反对）和"indication"（适应症）组成，意为"禁忌症"，即某种情况使得特定治疗手段不适用或存在风险。A项描述的是"indication"（适应症）；C项为"therapeuticresponse"；D项为"diagnosis"。43.【参考答案】B【解析】B项使用标准医学术语"acutemyocardialinfarction"（急性心肌梗死），表达准确规范。A项"badheartattack"过于口语化；C项"gotstuck"不符合医学术语规范；D项"cardiacstop"应为"cardiacarrest"（心脏骤停）。医学英语强调术语的准确性和专业性。44.【参考答案】B【解析】"idiotypic"（idiotypic）指抗体分子可变区中特有的抗原决定簇，即"idiotope"（独特型），每个抗体分子的独特抗原特异性。A项描述的是constantregion；C项涉及补体结合区；D项Fc段与效应功能相关，非独特型范畴。45.【参考答案】A【解析】"performsomethingonsomeone"是固定搭配，表示"对某人进行某项操作/检测"。此处指"对疑似过敏反应的患者进行过敏测试"。B项"in"通常用于表示在某个范围内；C项"at"表示地点；D项"with"表示伴随，均不符合此搭配习惯。46.【参考答案】B【解析】"etiology"（病因学）指疾病的成因或起源，是医学术语中的核心概念。A项描述的是"therapy"或"treatment"；C项为"symptoms"；D项为"prevention"。了解疾病的病因对于制定治疗方案至关重要。47.【参考答案】D【解析】"sub-"和"infra-"均表示"低于、在……之下"。"sub-"如"subcutaneous"（皮下的）；"infra-"如"infraclavicular"（锁骨下方的）。"super-"表示"above"（上方），如"superficial"（表浅的）。本题考察医学英语前缀知识，D为最佳答案。48.【参考答案】B【解析】"prophylaxis"（预防）指为防止疾病发生而采取的措施，如疫苗接种、抗生素预防性使用等。A项为"therapy"（治疗）；C项为"diagnostics"；D项为"surgery"。预防医学在公共卫生中具有重要地位。49.【参考答案】B【解析】"recommend"后接that从句时，从句谓语动词需用虚拟语气"should+动词原形"，should可省略，故用"beoperated"。A项为陈述语气错误形式；C项"isoperated"不符合虚拟语气要求；D项"operated"缺少助动词。这是医学英语语法中的重要考点。50.【参考答案】B【解析】"cardi/o"是"heart"（心脏）的combiningform，常见于"cardiology"（心脏病学）、"cardiovascular"（心血管的）等术语中。A项"kidney"的combiningform是"nephr/o"或"ren/o"；C项"liver"为"hepat/o"；D项"lung"为"pneum/o"或"pulmon/o"。51.【参考答案】A【解析】"benign"意为"良性的"，其反义词为"malignant"（恶性的），常用于描述肿瘤性质。B项"benefit"意为"益处"；C项"benignant"为生造词；D项"benignancy"为名词形式但不常用。医学术语中"benignvs.malignant"是重要对比概念。52.【参考答案】A【解析】"hemostasis"意为"止血"，是机体阻止出血的生理过程，涉及血管收缩、血小板聚集和凝血cascade。B项描述的是"leukocytosis"；C项为"hematuria"；D项为"splenectomy"。止血机制是外科学和急诊医学的基础知识。53.【参考答案】B【解析】B项语法正确且医学术语规范，"hasbeendiagnosedwithdiabetesmellitus"使用现在完成时的被动语态，"diabetesmellitus"为"糖尿病"的标准术语。A项"have"主谓不一致；C项"were"与单数主语不符且"diabetic"为形容词/名词而非疾病名称；D项"isdiagnosing"语态错误，应为被动语态。54.【参考答案】B【解析】"-itis"是表示"炎症"的常用后缀，如"appendicitis"（阑尾炎）、"bronchitis"（支气管炎）、"arthritis"（关节炎）等。A项后缀多为"-ectomy"；C项后缀如"-ia"、"-sis"；D项后缀如"-scope"。掌握后缀含义有助于快速理解医学术语。55.【参考答案】C【解析】"iatrogenic"意为"医源性的"，指由医疗行为或干预措施引起的疾病或不良反应，如药物副作用、手术并发症等。A项为"naturalcourseofdisease"；B项为"geneticdisorder"；D项为"environmentaldisease"。医源性损伤是医疗质量监控的重要指标。56.【参考答案】A【解析】"pathology"（病理学）是研究疾病病因、发病机制、形态改变及功能影响的学科。B项"physiology"（生理学）研究正常生命活动；C项"pharmacology"（药理学）研究药物作用；D项"anatomy"（解剖学）研究机体结构。病理学是连接基础医学与临床医学的桥梁学科。57.【参考答案】B【解析】Gastritisreferstoinflammationofthestomachlining.Hepatitisaffectstheliver,pancreatitisinvolvesthepancreas,andnephritisiskidneyinflammation.Understandingorgan-specificterminologyisessentialinmedicalEnglish.58.【参考答案】A【解析】BPstandsforBloodPressure,avitalsignmeasurementindicatingtheforceofbloodagainstarterywalls.Itisoneofthefourmainvitalsignsroutinelymonitoredinclinicalpractice.59.【参考答案】C【解析】Aminoglycosides,suchasgentamicinandstreptomycin,arewellknownforcausingototoxicity(damagetotheear)andnephrotoxicity.Thisclassofantibioticsrequirescarefulmonitoringofbloodlevels.60.【参考答案】B【解析】Idiopathicreferstoadiseaseorconditionwithunknowncause.Forexample,idiopathicpulmonaryfibrosisisalungconditionwithnoidentifiablecause.Thistermisfrequentlyusedinclinicaldiagnoses.61.【参考答案】C【解析】Tremorsareaclassicsignofhypoglycemia(lowbloodsugar).Othersymptomsincludesweating,palpitations,andconfusion.Polyuriaisassociatedwithhyperglycemia,nothypoglycemia.62.【参考答案】B【解析】Myocardialrelatestothemyocardium,whichisthemusculartissueoftheheart.Myocardialinfarction,commonlyknownasaheartattack,occurswhenbloodflowtopartoftheheartmuscleisblocked.63.【参考答案】C【解析】Platelets(thrombocytes)arecellfragmentsessentialforhemostasisandbloodclotformation.Theyaggregateatsitesofvascularinjurytoformplugsandinitiatethecoagulationcascade.64.【参考答案】C【解析】Ultrasoundimaginguseshigh-frequencysoundwavestocreateimagesofinternalorgansandstructures.Itisnon-invasiveanddoesnotinvolveionizingradiation,makingitsafeforrepeateduse.65.【参考答案】B【解析】Peri-meansaroundorsurrounding.Pericarditisisinflammationofthepericardium,thesacsurroundingtheheart.Similarly,peripheralreferstostructuresaroundthecenter.66.【参考答案】C【解析】VitaminKiscrucialforthesynthesisofclottingfactorsII,VII,IX,andX.Deficiencycanleadtobleedingdisorders.Itisalsoknownasthe"coagulationvitamin."67.【参考答案】B【解析】Anormaladultrestingheartraterangesfrom60to100beatsperminute.Ratesbelow60indicatebradycardia,whileratesabove100indicatetachycardia.Athletesmayhavelowerrestingrates.68.【参考答案】B【解析】Hyperglycemiareferstohighbloodglucoselevels,commonlyassociatedwithdiabetesmellitus.Symptomsincludeincreasedthirst,frequenturination,andfatigue.Itistheoppositeofhypoglycemia.69.【参考答案】B【解析】Benigndescribestumorsorgrowthsthatarenotcancerousanddonotinvadenearbytissuesormetastasize.Benignconditionsaregenerallylessseverethanmalignantonesandmaynotrequireaggressivetreatment.70.【参考答案】C【解析】Thekidneysfilterbloodtoremovewasteproductsandexcessfluids,producingurine.Theyalsoregulateelectrolytebalance,bloodpressure,andredbloodcellproductionthrougherythropoietinsecretion.71.【
