SHOOL BUS

yesterday,i received of my friend's message.she said:the school bus as like as two peas on USA.but SU's shool bus are don't like the usual shool bus,it's whhite and longer than usual shool bus.i think the school bus is most convenient transportation
.however,personally speaking,i believe SU shool bus are very cold on moring. when i live in china,i heard that USA school bus collision with hummer in Indiana.it's  amazing!!stusents has a safety transportation environment.
