3．cctv_yehong: 老师你好请您帮助解释第四篇课文motoring technology 中这句话。 accidents cause many traffic jams，but there are more subtle interplays between vehicles that can cause jams even on a clear but busy road. such jams can be analysed using statistical tools. 我认为第四问题to call for help when the car gets jammed in the traffic 也涉及到了啊？ 谢谢! |
