What will the world of tomorrow look like？Many people today believe that technology is going to help solve some of the most difficult problems we have on Earth today.New technology may solve old problems，and it may also create new ones.No technology is perfect.Each has advantages and disadvantages，as these three examples.

    When we dream about the future，many of us think that we will be able to fly to the skies in our own personal flying car.We could fly at 480 km per hour，avoiding traffic lights and busy roads.However，if the cars become popular，there will be problems with traffic control.

    3 D printing is another new technology for the future.3 D printers are already used to make life﹣size models of car parts，and man﹣made body parts，such as ears.As we move into the future，3 D printing will change the way we make things and the way we treat sick people.The disadvantage is that such a machine is very expensive.

    Finally，people are trying to build a robot suit （套装）.This is an electronic suit.It allows people to lift heavy objects and walk a long way.It might help people walk again after an illness or an accident.However，one disadvantage at the moment is cost.

    Looking ahead，it is easy to imagine a future.We will be able to fly to work，print out a new pair of shoes or lift a car above our heads.Although there are some problems to solve before all of this is possible，we can certainly dream of a world. In this world，technology makes people's life easier and safer .It can solve some of the most difficult problems we have today.
