雅思口语part3：未来的手机会是怎样的？

Advent of smart phones
Dramatic changes
Not ary
Different sizes
Processor
Essence
Use my wild imagination
Envisage
Embedded into our glasses
Displayed on our spectacles
Voice-control the system without keyboard
Control the system by telepathy
Developing at an unprecedented speed
should not be surprised at any creation of human being
