[audio]http://sound.yywz123.com/tingbbs/voa/voa20120315.mp3[/audio]So far, fifty of the kindergarteners have been examined in a machine that shows brain activity. The goal is to study five hundred children using FMRI, or functional magnetic resonance imaging. The scanner uses a high-energy magnetic field and radio waves to "look" inside the body. Written tests are not always able to identify dyslexia or other problems. Professor Gabrieli says children can differ a lot in their abilities from day to day. 到目前为止，已经有50所幼儿园使用显示大脑活动的仪器对孩子们进行了检查。其目的是使用磁共振成像对五百名儿童进行研究。这台脑扫描仪器使用高能磁场和无线电波对身体内部进行检查。笔试并不总能诊断出阅读障碍或其它问题。加布里埃利教授表示，儿童的能力每天都会有很大差异。
