     My first performance (表演) in front of an audience was coming up soon.

     I tried as hard as I could to remain calm, but my heart was racing. I stared down at my sweat-covered,

shaking hands.

     I looked up again at the audience, realizing that these were real people. They were not just my mum and

dad, who would say, "Good job!" even if I messed up the entire piece.

     What if I had the wrong music? What if I played the wrong notes? 

     As it turned out, I was never able to answer these questions because the spotlight (聚光灯) was waiting

for me. I grasped my hands tightly together, drying off the sweat.

     Slowly I walked to the mud-brown piano in the center of the room. It contained 88 demanding keys,

which were waiting impatiently to be played. I swallowed the golf-ball-sized lump (隆起部分) in my throat

and sat down. Slowly, I opened the music. Next, I rested my still shaking hands on the ivory (象牙色的)

keys.

     As my fingers played across the keys, I was becoming more unsure of my preparation for this moment.

But the memory of my years of training came flooding back. I knew that I had practiced this piece so many

times that I could play it backwards if requested.

     Although at one point I accidentally played two keys instead of the intended one, I continued to move

my fingers automatically (自动地).

     My eyes burned holes into (were fixed on) the pages in front of me.

     There was no way that I was going to lose my concentration. To keep this to myself, I leaned forward

and focused carefully on the music.

     When I came to the end of the page, a warning went off inside my head: DON'T MAKE A MISTAKE

WHEN YOU TURN THE PAGE!

     Needless to say, I obeyed myself with all my heart and mind. And, proud of my "page-turning" feat (技

艺), I finished the rest of the piece without making a single mistake.

     After the final note died away, a celebration went into action inside my head. I had finished. I had

mastered the impossible.

某校化学兴趣小组设计了图示实验装置（图中省略了夹持仪器）来测定某铁碳合金中铁的质量分数。

⑴ m克铁碳合金中加入过量浓硫酸，未点燃酒精灯前，A、B均无明显现象，其原因是

①常温下碳与浓硫酸不反应；②     。

⑵写出加热时A中碳与浓硫酸发生反应的化学方程式     。

⑶B中的现象是：     ；C的作用是：     。

⑷待A中不再逸出气体时，停止加热，拆下E并称重，E增重bg。则铁碳合金中铁的质量分数为      (写表达式)。

⑸甲同学认为利用此装置测得铁的质量分数偏大，请你写出可能的原因：     。

⑹最后对所得测量结果进行评价，小组内有同学提出，本套装置在设计上存在多处缺陷而导致实验结果不准确，其中会导致铁质量分数测量值偏低是(任答一条即可)     。
