There are many kinds of friends. Some are always (1) you, but don’t understand you. Some say only a few words to you, but understand you. Many people will step in your life, but only (2) friends leave footprints.

I shall always recall the autumn and the girl with the (3) . She will always bring back the friendship between us. I know she will always be my best friend.

It was the golden season. I could see the yellow leaves (4) with the cool (5) . In such a season, I liked walking alone on the roads covered with leaves, (6) to the sound of them.

Autumn is a (7) season and life is uninteresting. The free clays always get me (8) . But one day, the sound of a violin (9) into my ears like a stream flowing in them ountains. I was so surprised that I jumped to see what it was. A young girl, standing in the wind, was (10) in playing her violin.

I had (11) seen her before. The music was so nice that I listened quietly. Lost in the music, I didn’t know that I had been (12) there for so long but my existence did not seem to disturb her.

Leaves were still falling. Every day she played the violin at the comer of the building (13) I went downstairs to watch her performance. I was the only listener. The autumn seemed no longer lonely and life became (14) . (15) we didn’t know each other, I thought we were already good friends. I believe she also loved me.

Autumn was nearly over. One day, when I was listening carefully, the sound suddenly (16) . To my astonishment, the girl came over to me.

"You must like music from the violin. " she said.

"Yes. And you play very well. Why did you stop" I asked.

Suddenly, a (17) expression appeared on her face and I could feel something unusual.

"I came here to see my grandmother, but now I must leave. I once played very badly. It was your listening every day that (18) me." she said.

"In fact, it was your playing (19) gave me a meaningful autumn," I answered, "Let’s be friends. "

The girl smiled, and so did I. I never heard her play again in my life. I no longer went downstairs to listen to her. Only thick leaves were left behind. But I will always remember the fine figure of the girl. She is like a (20) —so short, so bright, like a shooting star giving off so much light that makes the autumn beautiful.

甲醇是一种可再生能源，具有广泛的开发和应用前景。

（1）工业上一般采用下列两种反应合成甲醇：

反应Ⅰ： CO(g) ＋ 2H₂(g)   CH₃OH(g)              ΔH₁

反应Ⅱ： CO₂(g) ＋ 3H₂(g)   CH₃OH(g)  +  H₂O(g)   ΔH₂

①下表所列数据是反应Ⅰ在不同温度下的化学平衡常数（K）。

由表中数据判断ΔH₁       0 （填“＞”、“＝”或“＜”）。

②某温度下，将2 mol CO和6 mol H₂充入2L的密闭容器中，充分反应，达到平衡后，测得c(CO)＝ 0.2 mol／L，则CO的转化率为        ，此时的温度为        （从上表中选择）。

（2）已知在常温常压下：

① 2CH₃OH(l) ＋ 3O₂(g) ＝ 2CO₂(g) ＋ 4H₂O(l)  ΔH₁＝－1451.6kJ／mol

② 2CO (g)+ O₂(g) ＝ 2CO₂(g)  ΔH₂＝－566.0kJ／mol

写出甲醇不完全燃烧生成一氧化碳和液态水的热化学方程式：                       

（3）某实验小组依据甲醇燃烧的反应原理，设计如图所示的电池装置：

①该电池的能量转化形式为              。

②该电池正极的电极反应为              。

③工作一段时间后，测得溶液的pH减小，则该电池总反应的化学方程式为            。
