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 220000 people have downloaded the app, and at any one time, between 8000 and 10000 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、An introduction to a mobile app that can record earthquakes.
B、A lecture about what to do when earthquakes strike.
C、An advertisement that promotes an app of alerting earthquakes.
D、A prediction of possible earthquakes in the future.
答案
A
解析
原文中提到,一款由加利福尼亚大学伯克利分校的研究人员开发的手机应用自从今年二月份正式推出以来,已经记录了将近400次地震。接下来的部分都是围绕这款手机应用展开的说明。因此答案为A。
