请你回答：

被人们亲切地称之为“指尖上的政民对话”的微信，因其一对一的双向性、私密性，进一步拉近了官民距离，官民互动更具实质意义，从而逐渐成为政府与群众沟通交流的新平台。政务微信的开通（    ）

①为公民求助、投诉提供了便捷的渠道

②表明政府的服务意识在增强

③调动了群众参与民主管理的积极性

④扩大了政府社会管理的范围

（1）25℃，在0.10mol•L^﹣1H₂S溶液中，通入HCl气体或加入NaOH固体以调节溶液pH，溶液pH与c（S^2﹣）关系如图（忽略溶液体积的变化、H₂S的挥发）．

（1）硫化氢的电离方程式为　 ____．

（2）往硫化氢溶液中加入少量的盐酸，硫化氢的电离平衡向 ____（“左”或“右”）移动．

（3）当调整溶液至pH=13时，请回答下列问题：

①c（S^2﹣）= ____　．此时溶液中的c（H₂S）+c （HS^﹣）= ____　．

②已知K_a1=$\frac{c\left(H^{+}\right)c\left(HS\right)}{c\left(H_{2}S\right)}$=1.3×10^﹣7，溶液中的离子浓度之间的关系为c （Na⁺）+c （H⁺）=c （OH^﹣）+2c （S^2﹣）+c （HS^﹣）．则c（Na⁺）= ____　（计算近似准确值）．

增加:在缺词处加一个漏字符号(/\),并在其下面写出该加的词。

删除:把多余的词用斜线(\)划掉。

修改:在错的词下划一横线，并在该词下面写出修改后的词。

注意:1）每处错误及其修改均仅限一词:

2）只允许修改10处，多者(从第11处起)不计分。

    I am used to be a naughty boy, who always made my parents annoyed from time to time. One day, as I was wandering around the field near my house, a cricket attracts my attention and I couldn't help catch it. I was noticed doing all this by Nick, a friend of mine, and he said to me, “Let's put the cricket on Selina's desk to frighten her, all right?”Of course I said yes, and I, together with him, were going to do just as what we had discussed. A few minutes before our trick, Selina saw it and was so frightened that she fell off the chair and broke his head, Afterwards, criticizing by my parents, I was made apologize to her. This lesson taught me a lot, warning me not to play a trick at other people. Since then, I have done things much well than before and become a man with manners and dignity.
