Visiting Mineral City!

    Mineral City is an interesting place to visit. It is a beautiful little town with many old buildings.

    Take a walk through the center of the town on Main Street. Look first at the Mineral City Hotel. It is on the corner of Main Street and Glenn Avenue. It is about 150 years old and people will stay there. There is an interesting old building across the street from the hotel. This was a post office. Now it is a store for books and videos. There are many places to eat on Main Street. You can get lunch or dinner in one of these places. There is a park between Main Street and Oak Street. You can sit on a bench（长凳）in the park. It is nice and quiet, and you can enjoy the trees and flowers.

    You can also take a walk down Glenn Avenue. Look at the old buildings and interesting little stores on this street.

材料一：“您有一个包裹未取”、“您的电话即将停机”、“某某啊，明天到我办公室来一下”…很多人接到过类似的诈骗电话。近几年，此类诈骗方式不断翻新，范围也扩大到学生群体。最近，山东、广东等地发生遭电信诈骗，导致受害人猝死、自杀的案件引起社会广泛关注。这种现象的出现也有些是由于我们对个人信息的保护不够重视，因此，同学们要提高警惕，提防诈骗的“花把式”。

材料二：2016年11月7日，十二届全国人大常委会第24次会议表决通过了《中华人民共和国网络安全法》。该法在保护个人信息、治理网络诈骗、网络实名制等方面划出了网络世界不可触碰的“红线”。如对非法买卖个人信息的企业、机构、个人即使无所得也可最高罚百万元。该法于2017年6月1日起施行。
