Subject: How does a CE mode single stage transistor used as an amplifier ?

In The CE mode single stage amplifier, when the ac signal is used as an input,
the emitter in the transistor is subjected to repeated forward and reverse
biasing, then how does the transistor reproduces the amplified ac signals as
output since the emitter-base junction should always be forward biased ? How
does the transistor actually work under this condition ? I hope for a quick
reply. I'm impressed with your present service.
