I found out that sometimes doing someone a favor could get you into a lot of trouble. I was in the eighth grade at the time, and we were having a final test. During the test, the girl sitting next to me said something to me, but I didn’t understand. So I got closer to her and found out that she was trying to ask me if I had an extra pen. She showed me that hers could not write. I happened to have an extra one, so I took it out of my pocket and put it on her desk.

Later, after the test paper had been turned in, the teacher asked me to stay in the classroom when all the other students were out. Then she began to talk to me about honesty and emphasized(重点强调) the fact that when people do something dishonest, they are really cheating themselves. She made me promise that I would think seriously about all the things she had said, and then she told me I could leave. I walked out of the room wondering why she had talked to me about all those things.

The next day, I realized that the teacher thought I had cheated on the test. When she saw me talk to the girl next to me, it looked as if I was copying answers from the girl’s test paper. I tried to explain about the pen, but she said it seemed very strange to her that I hadn’t talked of anything about the pen when she talked to me after the test. She continued to believe that I had cheated on the test.

某城市做出了冬季市区禁止使用原煤取暖的规定，暂不具备集体供暖条件的居民可使用“环保煤”取暖．原煤中含有FeS₂，燃烧过程中产生的SO₂（4FeS₂+11O₂

高温  .

2Fe₂O₃+8SO₂）将对空气造成严重污染．向原煤中加入适量石灰石就可以制成“环保煤”，通过2CaCO₃+2SO₂+O₂

高温  .

2CaSO₄+2CO₂反应，消除SO₂对空气的污染．现有含FeS₂质量分数为5.7%的原煤1000kg，理论上需加入纯度为95%的石灰石多少千克才能制成合格的“环保煤”？
