1、Unit 2单元话题阅读理解专项练习(名校最新真题)（2022四川凉山高二期末）A new phone app uses vibrations (振动) from smart phones to alert people about earthquakes. The phone app recognizes sudden shaking of the earths surface through sensors (传感器) in smart phones. The new app is called MyShake. It is the work of four researchers at

2、the University of California, Berkeley. They said they created a worldwide warning system that would inform people and give them time to prepare. The MyShake app is available only for Android phones. Smart phones are equipped with accelerometers (加速计) . These instruments measure movement, like that

3、of a car or airplane. They can also measure the shaking of a machine, building or other structure. Accelerometers are used in activity trackers and apps that count steps or other exercise. They are also used in global positioning system (GPS) apps. MyShake uses phone accelerometers to measure seismi

4、c (地震引起的) activity. It has been programmed to know the difference between normal activity and earthquake movement. The software developers say their app is right 93 percent of the time. A smart phone sends seismic information to the app developers. If the developers receive information from one area

5、, it recognizes that an earthquake may be taking place or will take place soon. Using information sent from the app, the network then estimates the location and strength of the quake in real time. MyShake can record magnitude (规模) 5. 0 earthquakes at distances of 10 kilometers or less. MyShake uses

6、very little power, according to its developers. Only when seismic activity is sensed by the app does it become active and sends data to the network. The app works best when your phone is resting on a flat surface, like a table. The app also shows ways to stay safer during an earthquake. The develope
