　　B段

　　If you have a bad habit of losing things, a new device that can be connected to any item that you might lose may be the way to solve your problem. The Tile, a small square linked up to your iPhone or iPad via Bluetooth, lets you see how close you are to the missing item, within a 50-to 150-foot range . If the item goes out of your phone’s 150-foot range, it can still be detected (发现) on other smartphones with the same app.

　　When you log into the app on your phone, it shows you, with green bars that increase or decrease, how far away you are from the Tile. You can also program it to make a sound when you get close to the Tile. And you can link up your phone with up to ten Tiles. And if your lost item — a dog, for example, or a stolen bike — goes out of your own phone’s 150-foot Bluetooth range, you can set it as a “lost item”. If any of the phones with the Tile app comes within the range of your lost item, a message will be sent to your own phone, reminding you of its position. The Tile app also has the function to remember where it last saw your Tile, so that you can easily find where you left it.
