1. Today we will talk about the life in the cities
PAST
The cars were very expensive and only a few people could have them
The houses were larger and the families were more numerous
The people dressed acording to their own ideology
PRESENT
Today is easier to get a vehicle. This creates traffic jams on the streets
The houses are smaller to accomodate fewer families
The air and wáter are the most polluted today
FUTURE
The machines will be powered by solar energy
The traffic will decrease because cars can fly
In the future we can talk with people from other planets
