@fansy,
in which the verb "modify" is used. But can we also use "to adjust"?
For the past 20 years, China’s HSR system, as compared with the level of HSR development in Germany, France etc., is believed to be at the initial phase. However, with the release of the 2008
modified version of Mid-to-Long Term Rail Network Plan, China’s HSR network appears to be overtaking Europe to become
the leader of the world.
I suspect you mean the underlined word. That's an adjective, Fansy, and yes, you could change it to the adjective form
adjusted, but to me
adjusted carries a more loaded meaning while
modified implies a more neutral meaning.
