杭州图书馆对所有读者免费开放，包括乞丐和拾荒者，这条消息引起热议。有识者认为杭图的做法击中了“社会软肋”。请结合下列材料，探究这里暴露的到底是哪些“社会软肋”？

    面对杭图的做法，部分高端读者选择离开。精英们担忧，如果是读书，当然可以；如果乞丐和拾荒者是支聊天，休息，孵空调呢？建议设立专区和附加门槛条件。乞丐也是城市的管理者纠结，这些年关于乞丐的新闻经常是某地警方提醒市民谨防乞丐行骗，某市政府为迎接国际会议把全市乞丐“集中起来”直到会议结束之类。

    杭图馆长褚树青说：“图书馆是一种公共产品，必须遵循公平原则。我无权拒绝他们入内读书。但您有权选择离开。”阿根廷国家图书馆馆长博尔赫斯有一句名言：“如果有天堂，天堂应该就是图书馆的模样。”

    政府投巨资建的图书馆，很多在冷清中坚守，要么书很少，要么人很稀，甚至将部分房间改为店铺出租给私人。服务质量难如人意，环境建设、管理不到位。

（《中华活页文选》）

       There is no doubt that mothers play an important leading role in the lives of their children. But what about a father's role? I believe that fathers play just as important a role as mothers.
       Fathers give us support. They are the shore（岸）we swim to when our arms and legs feel increasingly tired. They are the strength we rely on （依靠）as we take our first steps into the world. Fathers can be gentle and powerful, but they probably have the simplest love we ever know.
_______, the father is their first hero and possibly the only man they will ever feel comfortable loving.
For daughters, the father is the first man they admire and the first man whose eyes shine with happiness when they look at them. He is the first man to fall in love with them.
        For mothers, the father of our children is the person we can believe in to watch over the babies as closely as we would. We are protectedin the knowledge of their love. A father is the person on the planet with whom we can do whatever we want ... one who will be just as interested and never feel bored in the face of our devotion.
        Without fathers, we wouldn't be mums. I would like to thank them from all our hearts for this honor and for being our partners in the business of raising children.
