我想know fan 的用途！！！10g

I like fan very much. It is really one of the great inventions to us especially during summer days.

There are a lot of advantages in using fan:
1. It cools down our body temperature after school, meal, and exercise etc.
2. It makes air circulation to cool a room.
3. It reduces moisture in a room during rainy day.
4. It blows away the dust.
5. It blows away mosquitoes, flies that are not welcomed.
6. Compared with air conditioner, fan consumes less energy.
7. Compared with air conditioner, fan saves more money.
8. Most of all, compared with air conditioner, fan is more environmental friendly and helps to save the earth.

Finally, for the sake of the earth we are living on, we should bear in mind to turn off the fan when we are away to save energy.
