9. What’s your opinion about eating and drinking on subway?

　　As far as I am concerned, eating and drinking on subway trains are indeed not proper behavior, but it is also not reasonable to deprive citizens of that right. Eating and drinking on subway trains should be discouraged. Announcements and posters could be used to encourage people to create a better environment. With regard to the pregnant, the elderly, the sick and the weak, the government can allocate them special room to eat and drink.
