飞跃的

The quantum leap in writing technology came with the introduction of personal computers.

个人电脑带来书写技术飞跃发展。

I was so eagre to convince others I was actually older than I looked, and i would always wear my mum's dark colour clothing at the beginning of my teaching career.

除看大量书外，也拜师父，更重要是接触大量真假古董。东西看多，便有从量变到质变飞跃。当然本人天分和视觉记忆力还是出类拔萃。
