改成to be 这句子也是错的,没有主句,although引导的是从句.哥=你帮我改个正确的好吗？把although 去了，is 改为 which is .如果你非要表达转折，可以再聚首用however。however it which isnot uncommon for the schooling prevalent around our life. 这样吗？？ 哥我理解能力不好啊！你给我写个完整的好吗？求你了！However, it is not uncommon for the schooling which is prevalent around our life.记得设为最佳啊i give you 10 point again.thks ~
