小王发现黑暗中生长的大豆幼苗比阳光下生长的大豆幼苗高得多。请设计一个实验方案，探究不同光照强度对大豆植株高度的影响，并预测实验结果。实验材料和用具：大豆种子(200粒)、光照培养箱(光照强度范围0-10000Lux，温度、湿度等均可自行设定)、培养皿、直尺等。

MIDI enables people to use （） computers and electronic musical instruments. There are actually three components to MIDI, the communications " （） ", the Hardware interface and a distribution （） called "Standard MIDI Files". In the context of the WWW, the most interesting component is the （） Format. In principle, MIDI files contain sequences of MIDI Protocol messages. However, when MIDI Protocol （） are stored in MIDI files, the events are also time-stamped for playback in the proper sequence. Music delivered by MIDI files is the most common use of MIDI today.
