坐公交车会花掉20分钟。楼主可能是对take这个词的用法比较陌生。我给你先来几个例句：对一个运动员来说，跑五公里只要花16分钟。It takes an athlete 16 minutes to finish five kilometers.改变会出现的，但需要时间。Change will come,but it will take time.他们需要两天来调整，因为他们奔波很久了。It takes two days to acclimatize because they have been traveling for a long time.
bus ride是指乘公共汽车。比如：她住的地方到学校坐公交车就几站。She lives just a short bus ride from school.去城里只要坐二十分钟的车。It’s only a twenty minutes bus ride to town.
