An application, or app, developed by researchers at the University of California, Berkeley, has recorded nearly 400 earthquakes since it was launched in February this year.
    The app, called MyShake, runs in the background on smartphones with the Android operating system, uses a device’s motion detectors to measure ground motion, and then sends that data back to the Berkeley Seismological Laboratory for analysis.
    Designed to build a worldwide network of smartphone earthquake detectors, the eventual goal of the researchers is to send early-warning alerts to users a bit farther from ground zero, giving them seconds to a minute of warning that the ground will start shaking and prompting them to take cover or switch off equipment.
    As of this week, when an updated version of the MyShake is available for download, nearly 220,000 people have downloaded the app, and at any one time, between 8,000 and 10,000 phones are active, namely turned on, lying on a horizontal surface and connected to a WiFi network, and thus primed to respond.
    The updated app provides an option for push notifications of recent quakes within a distance determined by the user. " The notifications will not be fast initially, not fast enough for early warning, but it puts into place the technology to deliver the alerts and we can then work towards making them faster and faster as we improve our real-time detection system within MyShake," said project leader Richard Allen.
    Questions 9 to 11 are based on the passage you have just heard.
    9.What is this passage mainly about?
    10. What is the researchers’ ultimate purpose of designing MyShake?
    11.How will MyShake improve in the future?

选项 A、It will deliver more accurate notifications.
B、It will provide alerts within longer distances.
C、It will accelerate its speed in terms of notification.
D、It will offer life-saving services to earth-stricken areas.

答案 C

解析 短文中提到了MyShake项目负责人的话,指出这个应用开始的时候发送通知的速度不快,达不到早期预警的目的,但它运用了发送警报的技术,并且可以通过改善MyShake内部的即时探测系统来使它的运作速度越来越快。由此可以判断,未来MyShake将在发送通知的速度方面有所改进,因此答案为C)。
