考点03 阅读理解说明文 Passage1（2021·河南洛阳市·高三二模） Secret shower singers are pleased: a new water-powered Bluetooth speaker from Ampere could help arrange your morning routine. Shower Power attaches to your shower head, making your water flow power a hydroelectric generator(水力发电机) that charges the battery of its Bluetooth speaker. The device(器件) is similar to earlier water-powered speaker Hyquadio, but Ampere offers more options for controlling its speaker, with physical playback controls on the device and a battery-powered remote if the speaker is out of reach. When the speaker is attached and water is flowing, its 2500mAh battery should offer over 80 hours of playback at max volume(音量). With water off, that number falls to around 17 hours at max volume. Ampere explains that due to the size of Shower Power’s impeller(叶轮) it’s only able to meet the demands of the speaker’s battery at around 60-70 percent volume. Droplet, Ampere’s additional speaker accessory(附件), could help create a wider range of possible sounds. It’s the same speaker as Shower Power, but not water-powered. The device can be connected to Shower Power and it can be placed anywhere, filling out the sound in places Shower Power might miss fixed on your shower head, if you’re willing to purchase the device separately of course. Standalone water-proof speakers can also easily play music in your shower, but unlike Shower Power they’d have to be removed every time you need to charge them. Shower Power never has to leave your shower; its advantage is that it never requires you to remember a wire. For interested shower singers and podcast devotees, Shower Power launches today on Kickstarter for $59. You can add on the water-proof remote for $15 or an additional Droplet speaker for $20. Pre-orders will follow on Ampere’s site on November 15th and the device will go on sale in December. 1．What differs Ampere Shower Power from Hyquadio? A．Being water-powered. B．Being water-proof. C．A playback remote. D．
