在公共汽车上,我经常发现一些年轻人不主动让位。虽然司机叔叔一遍又一遍地播放“请主动给老弱病残孕以及抱小孩的同志让座,谢谢”,但有时收效甚微,有人甚至立即假装睡觉。我想发明一个座位震动器。将它安装在座椅上,只要按下开关,座位就会震动,提醒座位上的人给身边需要帮助的 On the bus, I often find that some young people do not take the initiative to give way. Although the driver uncle played over and over again, “Please take the initiative to old and sick pregnant and hold the gay seats, thank you,” but sometimes little effect, and some even pretend to sleep immediately. I want to invent a seat vibrator. Install it in the seat, just press the switch, the seat will vibrate, to remind the seat of the people around to need help
