材料一:青霉素的发明与使用揭开了人类与病菌抗争的新篇章。当今,抗生素被许多人当成包治百病的“灵丹妙药”。由于抗生素的滥用,无意中培养出了许多“超级耐药菌”。
材料二:乙肝是乙型病毒性肝炎的简称,是一种常见的传染病。据世界卫生组织报道,全球每年约有100万人死于感染所致的肝衰竭、肝硬化和肝癌。乙肝病毒主要通过血液这一渠道传播,在日常生活中共用剃须刀、牙刷,就医检查治疗过程因使用未经严格消毒而又反复使用被乙肝病毒污染的医疗器械都会引起感染。世界卫生组织的官网上对于乙肝传播有着非常明确的说法——乙肝病毒并不通过以下渠道传播:共用餐具,母乳喂养,拥抱,礼仪性接吻,握手,咳嗽,同一教室上课,或在公共游泳池玩耍或类似行为。
材料三:近年来,越来越多的家庭喜欢养狗,这为狂犬病传播带来隐患,全国狂犬病发病率有上升趋势。狂犬病是一种由狂犬病毒所致的人畜急性传染病,狂犬病一旦出现症状,死亡率几乎达到100%。
(1)细菌耐药的变异,对个体生存有利,并容易遗传给下一代。因此,“超级耐药菌”的出现,可以用达尔文的________学说解释。
(2)在使用青霉素前必须对患者进行皮试,否则有些患者会因为对青霉素过敏而发生休克甚至死亡。过敏反应是人体________功能的体现。
(3)乙肝疫苗由乙肝病毒灭活制成。新生儿出生后24小时内即应先接种第1针乙肝疫苗。从预防传染病的措施分析,给婴儿进行预防接种属于________
(4)从传染病流行的三个基本环节看,携带狂犬病病毒的狗属于________。预防狂犬病的唯一措施是在被动物咬伤前或咬伤后及时注射狂犬疫苗,狂犬病疫苗进入人体后,刺激淋巴细胞产生抵抗该病原体的特殊蛋白质,即________,从而将入侵的病原体消除。

A young man went to the local expert(专家) on gems and said he wanted to become a gemologist(珠宝家). The expert turned him down because he feared the youth would not have the patience to learn. The young man asked for a chance. Finally, the expert told the youth, "Be here tomorrow."
The next morning the expert put a jade(玉) stone in the youth's hand and told him to hold it. The expert then went about his work, cutting, weighing and setting gems. The boy sat quietly and waited.
The following morning the expert again put the jade stone in the youth's hand and told him to hold it. On the third, fourth and fifth days, the expert asked the young man to do the same thing. On the sixth day, the youth held the jade stone but he could no longer stand(忍受) the silence. "Master, when am I going to learn something?" he asked. "You will learn." the expert said and went about his business.
Several more days went by and the youth almost lost his patience. But one morning as the master put the stone in the youth's hand, the young man said without looking at his hand, "This is not the same jade stone!" "You have begun to learn." said the master.
Practice makes perfect. The experience we learned from practice teaches us and develops our abilities. Experience is the best teacher. Even the most successful person had no absolute confidence once. It is experience that gives people confidence. The truth is: if you do the work and gain the experience, you'll have more confidence because you'll actually know what you're doing.
