talforsuccessfultreatment,"saysDiffey.Ifit'scaughtbeforeitspreadstootherpartsofthebody,thepatientwillhave99%ofchancetosurviveforfiveyears.Ifit'scaughtlate,thatcandropto25%.Warningsignsareamolethat'schangingsize,shapeorcolour,oronethat'sasymmetrical—sometimesreferredtoas"uglyduckling"moles.Ifyouhaveconcerns,talktoyourdoctor.可知,最后,你应该注意你的痣。“黑色素瘤的早期发现对成功治疗至关重要,”迪菲说。如果在病毒扩散到身体其他部位之前被感染,患者有99%的机会存活5年。如果发现晚了,这个比例会降至25%。痣的大小、形状或颜色发生变化,或者不对称——有时被称为“丑小鸭”痣。如果你有疑问,去找你的医生。由此可知,病情早发现,治病好一半。?故正确答案为C。4.主旨大意题。文章主要介绍了黑素瘤发病的原因,病情介绍以及治疗方法。主要讲述了只在夏季涂防晒霜是一个错误的观点,也要注意冬天的紫外线。A项,“发现黑素瘤”,不符合文意,故排除;B项,“当心冬天射线”,符合文意;C项,“监控你的摩尔数”,不符合文意,故排除;D项,“少花点时间在户外”,不符合文意,故排除。故正确答案为B。七、答案:1.B;2.C;3.D;4.A解析:1.词义猜测题根据第一段第一句,在apoornight’ssleep后喝一杯浓咖啡是许多人早上需要的动力。2.细节理解题根据第五、六两段可知三次实验中受试者都喝了asugarydrink。3.细节理解题由最后一段onenightofinterruptedsleepdidnotworsentheparticipants’bloodsugarandinsulin(胰岛素)responses以及strongblackcoffeeconsumedbeforebreakfastactuallyincreasedthebloodsugarresponsebyaround50%可以推知。4.推理判断题由最后一段可知研究者通过比较实验结果得出结论。
