　　You must have heard of Nobel Prize. But do you know where it comes from? The answer is: Alfred Nobel.

　　Alfred Nobel, the great Swedish inventor and industrialist(实业家), was born in Stockholm on October 21, 1833, but moved to Russia with his parents in 1842, where his father, Immanuel, made a strong position for himself in the engineering industry. Immanuel Nobel invented the landmine(地雷) and made a lot of money from government during the Crimean War(克里米亚战争), but went bankrupt(破产的) soon after. Then, the family returned to Sweden in 1859, where Alfred began his own study of explosives(炸药) in his father's lab. He had never been to school or university but had studied privately(私自的), and by the time he was twenty, he became a skillful chemist and excellent linguist(语言学家), speaking Swedish, Russian, German, French and English. He built up over 80 companies in 20 different countries. But seldom happy, he was always searching for a meaning to life, he never married. He spent much time and money working on how to end the wars, and thus peace between nations, until his death in Italy in 1896. His famous will, in which he left money to provide prizes for outstanding work in physics, chemistry, physiology(生理学), medicine, literature(文学) and peace, is a memorial to his interests and ideas. And so, the man is remembered and respected(尊敬) long after his death.

】阅读《塑料瓶装水真的干净吗》完成下面题目（7分）
①出门在外，口渴的时候我们都习惯买一瓶水喝，瓶装水给我们的印象是干净和方便，尤其是高档瓶装水都会标榜自己“出身清白”，“从未受到过人类污染”。例如,“王岛云雨”产自澳大利亚塔斯马尼亚岛,那里号称拥有世界上“最干净的空气”,雨水自然清洁无比；“公元前1万年”产自号称“地球上最古老的水源”——加拿大卑诗省沿岸的冰川，水质更是纯正无比。然而，科学家指出，塑料瓶装水也有可能“不干净”。
②英国化学研究人员威廉·肖迪克表示，装饮用水的塑料瓶生产过程就有污染隐患，因为在制造瓶子的过程中，会使用含有锑元素的化合物作催化剂，随着塑料瓶的成型，锑元素也进入了塑料中。塑料瓶可能会持续向瓶中的水溶解重金属元素锑,这种元素长期积聚在体内可能危害健康。威廉·肖迪克对当地的15种热销瓶装水进行化学检验，结果发现天然地下水中的锑含量是万亿分之一，而刚出厂的瓶装水的锑含量平均为万亿分之一百六十。时间越长，塑料瓶中的锑元素在水中的溶解量越大，这个过程就像泡茶一样。出厂3个月后，瓶装水中的锑元素的含量竟然增加了一倍。然而，现在市场上大多数瓶装水包装上注明的保质期大多是24个月。另外，温度越高，锑元素在水中的溶解量越大，而人们对瓶装水需求量较大的季节是温度高的夏天。肖迪克表示，虽然摄入极少量的锑元素不会导致人生病，但是大量摄入则会诱发呕吐，甚至可能致命。
③美国哈佛大学的研究人员米歇尔等人发现，不少塑料瓶在加工过程中会加入名为“双酚A”（BPA）的化学物质。这种化学物质与出生缺陷、发育问题、心脏病和糖尿病患病风险高有关联。专家对它可能对人体健康造成的影响表示担忧，而一些国家已将该物质正式列为有毒物质。
④此外，荷兰研究者发现，瓶装矿泉水经常被细菌和真菌污染，污染的瓶装矿泉水对健康个体致病的危险可能有限，但对于免疫功能低下的病人和婴儿，则有更高的感染危险。
⑤英国“水与环境管理协会”的执行主席尼克·里夫斯还表示，瓶装水对环境的污染也不容忽视。全世界每年用于制造塑料瓶的塑料为270万吨，这些塑料的原料大多是从石油中提取的，仅在美国，制造这些塑料瓶就要消耗150万桶石油，这些石油可以供10万辆汽车使用一年。86%的塑料水瓶最后都变成了垃圾，需要400年至1000年才能降解。这些塑料垃圾在燃烧时会产生有毒气体和含有重金属的灰烬。
（摘自2011年5月《知识就是力量》，略有删改）
A.随着温度增高，时间增加，塑料瓶中的锑元素在水中溶解量会越大。
B.重金属元素锑一旦被人体摄入，就会诱发呕吐，甚至可能致命。
C.全世界每年用于制造塑料瓶的塑料为270万吨，这些塑料的原料大多是从石油中提取的。
D.专家认为，在塑料瓶加工过程中所加入的名为“双酚A”（BPA）的化学物质可能对人体健康造成影响。
【小题1】下列句中划线词语能否删去？为什么（4分）
(1)出厂3个月后，瓶装水中的锑元素的含量竟然增加了一倍。
(2)瓶装矿泉水经常被细菌和真菌污染，污染的瓶装矿泉水对健康个体致病的危险可能有限，
