最近，研究人员进行了一项关于手机对人们智力的影响的研究。他们发现，当手机在视线范围内时，人们在处理任务和记忆信息方面的表现会很糟糕。其中一位研究人员指出，尽管这些电子设备可以极大地便利生活，但手机总放在身边会导致认知能力下降。即使能够成功保持长期注意力，即能抵挡查看手机的诱惑，现有的认知能力也会因手机在场而降低。

参考译文：

Recently, a study concerning the effects of smart phones to our brain had been conducted by a group of researchers. They discovered that people are worse at conducting tasks and remembering information if they have a smart phone within eye shot. One of the researchers of this study points out that although smart phones have immense potential to improve welfare, their persistent presence may come at a cognitive cost. Even when people are successful at maintaining sustained attention—as temptation to check their phones—the presence of these devices reduces available cognitive capability.
