【答案】In my opinion ，there are a lot of changes in Beijing.I think the biggest one is transport.Now transport has become more and more convenient.We can take the bus，taxi，or underground.We can also ride shared bikes.
So for many people，life is a lot easier today because of the change in transport.Besides，people's choices for transport have also changed.More and more people would like to take the public transport，because it's good for our environment.That's why I think transport can be the biggest change in Bejing.
