I have never been so pressed for time until I took a pedagogic exam .I was writing from beginning to end,and my writing had not kept pace with my thinking completely....When I wrote the first word of the first sentence,I had already begun to think of the third sentence...An hour later,I felt my right hand had separated from my body....When teacher said it was half an hour left,I relaized my paper was not even half-complete yet..in the end I had finished all the essay questions left and I believed that no one could identify my writing...
