Day 7:
第四天的总结作业
In this passage,the writer lets us come into a wholly new world-space and time.During the reading, my largest gains are that time,which exists in my mind as fixed substance,turns out to not be absolute.It is impossible to understand such a concept!In the first day,to tell you the truth,I spent over one hour reading Space and Time.But the result is that I only understand one third of the content,even not accounting for half.Even a lot of knowledge is not accessible to me,while I still feel happy that it opens some new fields I've never touched for me,such as four-dimensional space called space and time.I would have lived in my own world where there is absolute time and time will never change no matter what happens,if I had no chance reading the passage.Time will change with shifted space and different observers.Thinking a farther field,we will find everything is in a state of change,and rest is relative.In the mortal world,nothing is eternally unchanging except the change itself.We must learn to be brave for every change,constantly learn new things,and stay foolish and thirsty for knowledge.
While reading,it is essential to remain thinking,say,be an active reader(catcher).
