阅读材料，完成下列要求。

材料一：临泉县城区也有了共享单车。共享单车在给人们带来便利的同时，也引发了乱停、乱放，被踩坏、被扔进湖里等一系列问题。杭州一家公司基于过去“小红车”还车难的痛点开发出虚拟“电子围栏”，市民通过手机客户端或者微信端扫取“小红车”车身的二维码后，可实现“无卡操作”。通过设置“电子驿站”，在车载定位装置中，设置市区内可停车区域，通过客户端对用户进行提示，从而实现在可停车区域“无桩停车”。共享单车的变革促使人们规范的使用市场资源，自觉遵守市场秩序，在方便自己的同时也要考虑到他人和社会。

材料二：分享经济是“互联网+”背景下诞生的一种全新商业模式，即利用互联网、大数据等技术，整合重构资源，通过分享、协作方式搞创业。如搭顺风车、百度外卖等，成本小、更灵活。互联网与各行业融合发展，已成为常态。分享经济实质上是一种信用经济，当前社会信用环境不够好是制约其发展的重要瓶颈。另外，资源分享双方的权利和义务意识比较淡漠，分享经济涉及的公民人身安全和财产安全一直是被社会关注的热点；相关法律的调整跟不上其发展速度，传统的监管手段和方法在分享经济面前也难以实施。

    The listening test is one of the most important parts of the English exams. Here are some tips on listening for you.

    Before you start to listen, you need to relax. Don't be nervous. And try to read the questions. These questions usually help you understand the dialogue or the passage.

    Then listen to the first sentence carefully. It usually tells you the main idea of the passage. When you're listening, try to do some thinking and take some notes(笔记), such as：

    What happened?

    When, where, and how?

    What does the speaker want to tell us?

    In this way, you may understand the passage better.

    Please remember not to think about one or two words for a long time. When you hear some words you don't know, don't spend too much time on them. Very often, you'll find out what they mean later when you go on with the listening.
