求一篇关于公交优缺点的三人英文对话,四分钟时长的,

(John,Peter,and Mary usually go to work by car pooling.While eating breakfast...):
John:Peter,why do you eat so fast today?
Mary:You seem to be in a hurry,Peter.Don't rush,we have enough time to get to work.
Peter:Guess what?I've decided to take a bus to go to work starting from today.
John:You must be kidding!
Peter:No,I'm serious.
Mary:But why?It takes a lot longer time to take a bus than a car to go to work.
John:Its simply a waste of time.I'm wondering how are you going to kill your time on the bus.
Mary:A waste of time is one thing,and the other is how can you tolerate the crowdedness on the bus?
Peter:I'm not worried about what the two of you just said.What concerns me the most is the increasinglypoluted air.Look outside,another day of severe smog.Can you see the number of pollluted days are ever increasing and most of the pollution is generated by cars.Although it takes longer by bus,the more people take the bus,the fewer cars will be on the road.So,by taking a bus,I'm doing my part to reduce the polllution and save our city.
John　and　Mary：　That　sounds　great!　We　will　join　you　to　save　our　earth．
ALL　Three：　Let＇s　hurry　before　its　too　late　to　catch　the　bus．
