请结合所学知识回答，我市采取这些维护社会公平的举措，对促进我市的社会稳定有何积极作用？ 

已知点A（0，﹣2），椭圆E： $\frac{x^2}{a^2}$ + $\frac{y^2}{b^2}$ =1（a＞b＞0）的离心率为 $\frac{\sqrt{3}}{2}$ ，F是椭圆的焦点，直线AF的斜率为 $\frac{2\sqrt{3}}{3}$ ，O为坐标原点．

（Ⅰ）求E的方程；

（Ⅱ）设过点A的直线l与E相交于P，Q两点，当△OPQ的面积最大时，求l的方程．

根据材料内容，选择正确答案。

    Two men are walking in the park. One is Jack, a worker. The other is Henry. Jack is going to a chair. It is next to the street. Henry is after him. Jack finds Henry walking after him. He walks faster(更快), because he wants to get to the chair before Henry. Now Henry begins to run because he also wants to get to the chair first. Then he gets to the chair first and sits down on it. When Jack gets to the chair, he sees Henry sitting on it. He is sorry to show a notice（告示）with the words “Wet Paint”（油漆未干）to Henry. Now Henry knows why Jack is going to the chair.
