阅读理解 A Japanese start-up called Ashirase is stepping into the global market with a new navigation (导航) assistance product intended to help people with low vision. Its new product will feature flexible vibrating (震动) bases around each foot and are put into each shoe, and a small pack that can be removed for charging (充电). Once fitted, the vibrating parts are set along the sensitive nerves on the foot and can send coded walking instructions to the user. Its present form navigates a route that comes from a smartphone app. It can help clear up distractions by freeing up the attention that is normally needed to either listen to voice directions or check the phone. Visual-damaged users can use their hearing to listen to traffic sounds and signals, like warning beeps at crossings or sidewalks, and use their hands to carry walking sticks or other belongings. The device is paired with an app through a Bluetooth connection. The app uses information from Google Maps or similar vendors to draw up a walking route to the destination. Based on the destination and how the user is walking, it will send signals to the device that will cause a vibration on the foot. The device will vibrate at a regular frequency at the front of the foot to let the users know they're on the right track and should keep going straight. It will speed up the vibrations once the user is approaching a turn and needs to stop, and it will vibrate in either the left or right shoe to signal the direction the user needs to turn. Ashirase's new tech is waterproof and washable. It can be charged at the end of the week to power through seven days of walking, accounting for three active hours each day. And it can be fitted in two types of shoes: sneakers and leather lace-up shoes. （1） Who can benefit most from this device? A . Deaf people. B . Blind people. C . Normal people. D . Poor people. （2） What is most likely to be needed to make the device work? A . A computer. B . Nothing else. C . A mobile phone. D . Both A and C. （3） How can the user know that he or she is on the right way? A . By how often the device vibrates. B . By the sound sent by the device. C . By the signals from their mobile phones. D . By how long the device vibrates. （4） What can we infer from the text? A . The device can be used for 21 hours a week. B . The device can't be washed or charged. C . The device can only be fitted into sneakers. D . People wearing the device can't hear traffic warnings. 答案： B C A A
