S1: We think that drug taking is particularly important. As we all know, drug taking does great harm to people's health; it will gradually kill a person if he gets addicted to it. Buying drug costs a lot of money, so many drug takers sell out their fortune to afford the drug they need. And as a result, many families break up in this way. We also know that our government has to spend a lot of money on drug addicts' treatment.

S2: We think parenting is the most important issue, because many issues arise as a result of bad parenting or lack of care and love. If children grow up in happy and healthy families, they will form good habits and keep away from those bad habits such as using drugs and smoking.

S3: Our group takes smoking as the most important issue. The reasons are: smoking does great harm to people's health, it causes damage to people's lung and heart; smoking shortens people's life-span; smoking not only does harm to people who smoke, but also affect the health of people around them, especially their family members.
