还原性铁粉在潮湿的空气中容易生锈。现有m1 g生锈的铁粉样品,某兴趣小组同学按下图所示装置进行实验,测定该样品中氧化铁的质量分数(铁锈按氧化铁处理)。

(1)装置A中反应的化学方程式是_____。

(2)某同学欲通过B装置反应前后的质量变化,测定该样品中氧化铁的质量分数。B中的最佳试剂是_____(填序号),实验时B中反应的化学方程式是_____。

① 澄清石灰水    ② 氢氧化钠浓溶液     ③ 稀盐酸     ④ 水

(3)上述实验过程中,CO气体除作为反应物外,还能起到的作用是:① 实验开始时,排尽装置中的空气,防止加热时发生爆炸;② 停止加热后,防止A中生成物被氧化,B中的溶液倒吸入A中;③_____。

(4)完全反应后,甲同学称得铁粉的质量为m2 g,同时测得装置B增重m3 g,则铁粉样品中氧化铁的质量分数为_____。

     It was Thanksgiving morning and in the crowded kitchen of my small home I was busy preparing the
traditional Thanksgiving turkey when the doorbell rang. I 1 the front door and saw two small children in

     "Any old 3 , lady ?"asked one of them. I was busy. I wanted to say "no" until I looked down at their
feet. They were 4 thin little sandals(凉鞋), wet with heavy snow.
     "Come in and I'll make you a cup of hot 5 ".
They walked over and sat down at the table. Their 6 sandals left marks upon the floor I served them
coffee and bread with jam to fight against the cold 7 . Then I went back to the 8 and started again on
my household budget.

The girl 12 her cup back in saucer(茶托)carefully and said, "Your 13 match you saucers. "Her voice was hungry with a need that large amount of food could supply. They left after that, 14 their
bundles of papers against the wind. They hadn't said "Thank you". They didn't 15 to. They had reminded
me that I had so much for which to be 16 . Plain blue china cups and saucers were 17 worth five pence.
But they matched.
     I moved the chairs back from the fire and cleaned the living room. The muddy 18 of small sandals were
 19 wet upon my floor. "Let them be for a while, "I thought. Just 20 I should begin to forget how rich I am.
