语 篇 提 能阅读理解The air piano was invented by Omer Yosha in Germany and the first air piano came out in 2008. Its called a piano but it has no keys, so you dont need to play keys to make it work. Users look like playing “in the air” when you see it being played.The air piano makes no sounds on its own and it needs to work by being connected with a computer. The air piano comes with its own software (软件) to control it and it has 24 separated keys and 8 sound controllers that are not on the screen but settled in a touchfree surface. Each of the eight sound controllers spread across the surface of the air piano can play three notes depending on the users hand position. The surface can be controlled by moving hands in the air above it.Driven by software, the instrument has a large number of notes and sounds available for users to play.

The idea of the air piano is to keep things as simple as possible in order to achieve full control over the instrument.语篇解读本文介绍了一种演奏者无需直接触摸琴键便能弹奏出美妙音乐的空气钢琴。1The air piano got its name most probably because _.A. it can create different music on its ownB. it is light and easy to move on the stageC. it can spread sounds over the airD. it is played without being touched答案与解析D根据首段中“Its called a piano but it has no keys, so you dont need to play keys to make it work.
