【正确答案】正确答案： We can see in the picture that some people eat and drink on the subway ignoring the Food Banning indication. This is a common phenomenon in our daily travel and the topic whether food should be banned on the subway has sparked heated discussion. But in some cities like Wuhan, eating and drinking have been forbidden on the subways. First, eating stinky food will disturb other commuters and the whole cabbage will be filled with the smell, since it's poorly-ventilated in the cabbage. Secondly, people who eat and drink may litter away on the subway. The trash remained by the passengers can attract rats and cockroaches, which may influence the normal commute of the subways. Above all, I hold that food should be banned on the subway. It may bring some inconvenience to some people who have no time to have breakfast in the morning, but the clean and safe traveling environment for all is much more important.
