Welcome to your alma mater!
Standing here, the teacher remembered a program "Yesterday, Today and Tomorrow" in Zhao Benshan in the Spring Festival Evening. Now the teacher is also reviewing according to this idea.
Yesterday, today and tomorrow, if you look at it as a whole, you can use the unit "1", and each copy is one third.
Let's review the first and third first. Yesterday, the teacher spent three years and six semesters with you, * * * 147 weeks, that is, 1029 days. These days, many unforgettable things have happened. I remember in April this year, some students complained to the teacher that some students played pranks and always liked to hide other students' stationery at noon. After a survey of Detective Conan, the conclusion is that eight male students participated in this matter, so the teacher was honored as a "great hero" by the female compatriots in our class. In May, another classmate replied to me. Some students in our class read "romance novels". After careful investigation and evidence collection, there are 8 students, but all of them are girls. I thought to myself, hey, eight men and eight women are really symmetrical. Isn't this the "symmetrical beauty" that we emphasize in mathematics? At this time, unfortunately, I was called "the big bad guy" by my female classmates. From "great hero" to "great villain", it fully shows that "the possibility of things happening" is half. In short, the previous dribs and drabs left an unforgettable impression on the teacher.
It's time for the second third. For today, let's meet again in the small town, and there are always infinite memories in our hearts. Just looking at the pictures scrolling on the big screen, the teacher thought of the scene when I selected these pictures yesterday. I pulled all your photos from the computer and counted them carefully, which may be a coincidence; I carefully selected some for Miss Liu and asked her to help me choose some. After the first round of selection, I counted 64 more, which may be a coincidence. I said, Miss Liu, I have to remove half of it. There are too many photos. Teacher Liu said while choosing that this red leaf can't be deleted. It's so cute to wear a small tie. This old story, like a small landlord, cannot be deleted. Teacher Zhu, who was sitting there correcting the test paper, leaned in, smiled while watching it, and said from time to time: These children's proposals are really cute. But today most of them were deleted by Teacher Su.
Time is up for the third part. Tomorrow you will fight for your ideal, and the teacher hopes that you will be happy and healthy every day. I hope all the students here can visit their alma mater frequently.
In fact, yesterday, today and tomorrow, aren't they all the axes we have learned? Yesterday is equivalent to the negative part, which requires us to read and review from time to time in our minds; Today is equivalent to "0" in the middle, reminding us that everything should start from "0", so we should make good use of today; Tomorrow is the positive part, which gives us infinite reverie. I hope you will make more efforts to expand the length and breadth of "positive numbers".
Finally, I sincerely give you three numbers. Look at my gesture and say 5, 2, 0 together. Yes, I love you, thank you!
