Now,at the beginoing of 2008,a big event has occurred in the international market that has shocked the world： On January 2, the first trade day of the New Year, the crude oil price jumped to US$ 100 per barrel, creating a new record and surpassing the previous record high of US$ 99.29 a barrel from 2007. Whether the increase can be attributed to tensions in Pakistan or the Middle East,
Yet,is the US$100 per barrel an important turn- ing point or just a psychologically nerve-wrack- ing number?Only the ongoing and updating his- tory will provide the answer.
