"We can't play computer games for a long time" 可以用英语表示为 "We shouldn't play computer games for extended periods of time"。
这种表达方式源自于对长时间玩电脑游戏可能对身体健康和学习/工作效率的影响的关注。例如：
"Prolonged gaming can lead to eye strain, headaches and poor posture."（长时间玩游戏可能导致眼疲劳、头痛和姿势不良。）
"Spending too much time playing video games can negatively impact academic performance."（花太多时间玩电子游戏可能对学业表现产生负面影响。）
