From VOA Learning English, this is the Technology Report. 这里是美国之音慢速英语科技报道. Brain imaging was once thought to be too costly and difficult for widespread use in the developing world. But the technology soon may be available in poor countries. Brain imaging creates pictures of brain activity. It uses infrared light -- similar to the light produced by a television remote control. Brain imaging can identify the first signs of cognitive delays, mental problems, in newborns and young children. Such children could be suffering from malnutrition – a poor diet. 脑成像曾被认为太昂贵而难以在发展中国家普遍使用.但是该技术不久后将在贫穷国家中得以应用.脑成像采用类似电视遥控器产生的红外光生成大脑活动的图像.脑成像可识别新生儿和幼婴的认知延迟和智力障碍的初期迹象.这类孩子可能营养不良或饮食不良. The technology has a long name -- functional near-infrared spectroscopy, or F-N-I-R-S. 该技术有个很长的名称--功能性近红外光光谱仪(FNIRS). _______________________
