In the class comments on March 4, 2065438/kloc-0, the students were still a little uncertain about a+ ordinal number+noun singular number = doing something again. I also gave an example in class: his parents have two children, but they want a third one. His parents have two children, but they want another one. "That is to say, the third child is born on the basis of the first two"). It shows that this structure not only means "again, again", but also shows that "ordinal number-1" has been carried out before. Wang Longjuan, a careful science student after class, corrected it for me. In the structure of "a+ ordinal number+noun singular number", ordinal number cannot be equal to one, that is, there cannot be a first. And still! ! Thank you for your correction, which proves that the students listened carefully in class, which shows that my class is still attractive, and I also want to applaud the students for their serious spirit of knowledge!

After class, I had a rest and was busy printing the relevant materials of the monthly exam. As a result, I finally waited and printed them out. When I got back to the office, I found that I forgot to print the sign of the examination room, and went there for the second time (suddenly I found that we also have the expression "a+ ordinal number+noun singular number" in Chinese, which is really the feeling of God's arrangement!
