     When I was eight, I attended school in Bath, England. It was a   1    school made up of four
classrooms altogether,   2   about 25 children in each one. For the most part, one teacher was   3   
teaching all of the subjects in each class.    4  , Mr Ronald Broaches, the headmaster, would   5   in
and teach some subjects. Although he was quite strict with the students, he had an excellent sense
of   6   . Many of the children were   7   by him because he was a very good man.
     In my own   8   , he took a great interest in me when he   9   that I enjoyed doing puzzles. He would
often stop me as I was going to class and   10   me a piece of paper, often with a mathematical or logical
puzzle on it.
   11   time went by, the puzzles gradually got more difficult, but I   12   them. They served to show me
that   13   activity was fun and rewarding when the correct   14   were found. Even today I can still   15   
Mr. Broackes' joyful exclamation (感叹) of"Well done!" whenever I worked out a puzzle. This simple   16  
with a man whom I admired greatly has had a deep influence on my life. I shall forever be   17   that our
paths crossed.

speak with him before his death. I learned later that he had heard about my   20  . I will always wish that
he knew what a deep influence he had on my life.

问答题

2009年3月11日凌晨,承建沪宁城际铁路的中铁集团的分公司在江苏省丹阳市为劳务人员租用的一处生活用房发生爆炸并坍塌,造成11人死亡、20人受伤.经初步分析,事故是由租用的生活用房地表及墙面残留的危险化学品铝粉粉尘遇水受潮产生化学反应,燃烧并爆炸而造成的.铝粉是一种银白色粉末.它能溶于酸、碱,生成氢气,受潮或遇水会发生反应,放出氢气和热量,如果积热不散,容易引起燃烧或爆炸.铝粉粉尘与空气混合,遇火星也会发生爆炸.由于铝粉容易燃烧和爆炸,因此应将其储存于干燥通风的仓库内,远离火种及热源.

请根据上述信息,回答下列问题:

(1)铝粉具有银白色金属光泽,常被用作油漆涂料,这是利用了铝粉的______性质(填写“物理”或“化学”);

(2)干燥的铝粉在空气中遇到明火极易爆炸,写出这个反应的化学方程式______

(3)根据铝粉的性质,你认为铝粉的下列保存方法不正确的是(______ );

A.储存于干燥通风的仓库内          B.远离火种及热源

C.隔绝空气密封保存                D.露天随地堆放

(4)在野外,铁路工人常把铝粉和三氧化二铁粉末按一定比例混合后点燃,反应生成高温的铁水,而把较短的钢轨焊接成较长的钢轨,请你写出该反应的化学方程式______,该反应属于______反应(填写基本反应类型).
