Lesson 15
Exercise 1.2
In many big cities in the world ,
the over use of cars is thought to be
one of the major causes of air pollution,
What will cars be like in the future?
Some experts think that today's cars are
in trouble because they use too much gas,
They say the car of the future will be much，
much smaller.
The car of tomorrow will be made without a
motor or air conditioning.
It'll have no radio and no lights,
Tomorrow's car will be an open air car
with no doors and windows,
It won't need a pollution control system
because it won't use gas .
In fact,this new car will be pushed
by the driver's feet,
Very few people will be killed in accidents,
because the top speed will be
five miles per hour.
However,we are also warned not to
ask for pretty colors,
because the cars will come in gray only.
Other car experts do not hold the same idea.
They are sure that the future will be happy.
They think that all our problems will
soon be solved by car companies
with the production of the Supercar.
Tomorrow's car will be bigger,faster,
and more comfortable than before.
The Supercar will have four rooms ,
color Tv,running water,heat,air conditioning.
and maybe a swimming pool.
Large families will travel
on long trips comfortably.
If gas is in short supply,
the Supercar will run on water.
