Chapter 169 Chapter 169: Geography Lesson Activity: Northern Hemisphere Treasure Hunt
As I kept tapping on the keyboard, the letters seemed to be finding their place.
Wu Zhen is becoming more and more confident that he will be able to turn on the computer's networking function in the next class.
After all, typing 20 words per minute isn't a difficult task.
When I came to school, the geography class immediately went to the meridians.
This is the difficulty of the geography exam, after all, it is very troublesome for us to determine the time of each time zone and find the time of the target place in the East 8th District.
And in the process, the zero degree meridian passing through the former site of the Royal Observatory in Greenwich, and the 180 degree meridian in the middle of the Pacific Ocean are also commonplace.
Therefore, questions such as "where and when does a certain yacht sail from a certain place in the sea go" often make children a little helpless.
So, on this day's class, I did an activity to simulate the weft.
Eight groups naturally become eight meridians. Rotate 360 degrees in one turn, so every 45 degrees is a meridian from zero degrees of longitude.
Thus, the eight groups were: zero degree longitude, 45° east longitude, 90° east longitude, 135° east longitude, 180° longitude, 135° west longitude, 90° west longitude, and 45° west longitude.
Since there were three time differences between each group, these time differences were solved at once.
Of course, there is also a lot of hilarity in the process.
Teacher Cao smiled and said: "This is my gossip map, if you have any problems, you will mark the eight lines in the sketchbook, of course, you must remember that a time zone is 15 degrees." ”
With the help of this thing, Wu's real geography homework is done very quickly.
Two days later, Mr. Cao added the weft to this operation.
So, the first row is cold, the second is temperate, the third is subtropical, the fourth and fifth are tropical, and the next is the same as the first, second and third rows, but upside down.
In this way, the whole globe is expressed in this way.
But then in the actual activity, everyone found that this is not convenient. Eventually, the latitude was changed to just the Northern Hemisphere.
As a result, it became the first and second rows of students to be tropical, the third and fourth rows to be subtropical, the fifth and sixth rows to be temperate, and the seventh and eighth rows to be cold.
Then, Mr. Cao started the happy "Northern Hemisphere Treasure Hunt" role-playing game.
The whole process of the game is that the whole class is equivalent to the northern hemisphere, and then, Mr. Cao casually reports the coordinates of a treasure: how many degrees north latitude, how many degrees east longitude or how many degrees west longitude. And the classmates who were in that place immediately stood up and said the report.
And in this game, Mr. Cao also communicated with Mr. Guan. So the Ban card activity is linked into this game, and all those who don't stand up in time will face the punishment of deducting a Ban card.
Therefore, this is equivalent to multiple tests for Wu Zhen, on the one hand, it is necessary to record the class card, on the other hand, it is necessary to record the deduction of the class card, and at the same time, it is necessary to pay attention to whether the place reported by Mr. Cao is not his own location.
Then, Wu Zhenzhen asked Yuan Li for help: "What should I do? I'm too busy." ”
Yuan Li smiled and said, "Haha, don't you know how to determine a range of warp and weft?"
Wu Zhenzhen asked, "What do you mean?"
Yuan Li smiled and said: "Do you think I am the fifth in the eighth group, and you are the sixth in the eighth group, so, longitude, we are 45 degrees west longitude, so we just need to pay attention to the latitude, and we all belong to the temperate zone, so I stand up and you just stand up." ”
So, Wu Zhenzhen then relied on standing up at the same time as Yuan Li and mixed up. In other groups, there are often two people standing and one person not standing, so the whole event is very lively.
The climax of the event was when four people stood up at the same time, and at the same time accused the people next to them of standing wrong. All of a sudden, everyone laughed.
However, as time went by, everyone heard that the latitude and longitude reported by Mr. Cao stood faster and faster, and became more and more accurate.
Mr. Cao saw that everyone was basically familiar with this pattern, so he said on the blackboard: "Okay, in order to prevent some Mr. Nanguo, so." The game mode was changed, and then these meridians were changed to between two groups, for example, there is a zero degree meridian between one group and two groups, and naturally the other meridian positions are still 45 degrees apart, and so on. ”
After a pause, Mr. Cao continued: "This latitude has also been adjusted, the first group of students is in front of 10 degrees north latitude, and the rows of students are separated by 10 degrees, until the eighth row of students is 90 degrees north latitude, which is the North Pole. By the way, when reporting to the latitude and longitude coordinates on the boundary, the students on both sides have to get up. ”
In this way, everyone is in a separate area of the northern hemisphere. So the game became tense again, because there was only one person corresponding to each position, so Wu Zhenzhen could no longer act with Yuan Li as before.
However, this game is actually quite simple, after all, there is only one coordinate range for this location. So, Wu Zhenzhen had no choice but to mark the range of longitude and latitude of the eight groups of six that he was in.
However, in the end, he still failed to react. After all, Wu Zhenzhen failed to take care of himself when recording the situation of other students. So, Wu Zhenzhen had no choice but to deduct a class mark for himself.
The next game has been going well, no matter where Mr. Cao reported, someone immediately stood up, and the whole longitude and latitude seemed to have been engraved into everyone's minds.
However, then Mr. Cao reported to a position, but no one got up for a long time.
After reporting twice, no one got up, so Mr. Cao said angrily: "Sleeping classmates hurry up." ”
A sleeping student sitting in the third row was immediately called up by a classmate next to him. Teacher Cao was about to say something, but suddenly found that this classmate was not in the place of latitude and longitude that he had reported.
"Who else is sleeping, stand up quickly, if you don't stand up, you will be deducted 10 cards from that ban. Teacher Cao said angrily.
However, no one stood up, so everyone followed Mr. Cao's eyes to look at the seat where the latitude and longitude that Mr. Cao had reported, and found that there was no one over there—it was the place where the broom was placed.
At this time, everyone immediately laughed, and Mr. Cao, who had been a little angry before, also laughed.
After laughing, Mr. Cao laughed at himself: "Haha, the grade is older, I can't see clearly, I always thought that the broom was a classmate lying there." It turned out to be a broom stuck upside down. ”
So, everyone laughed again.
And this lesson is coming to an end.
During recess, Xiaojie still occasionally communicates with Wu Zhenzhen, but it seems that there is a lot less communication than in elementary school before.
It seems that Xiaojie is playing a very fun game called World of Warcraft.
On this day, the two happened to communicate about this matter, and Wu Zhen asked: "Is World of Warcraft fun?"
Xiaojie said: "Don't mention it, you can't afford to play, and it will cost you money to get on the number." ”
Wu Zhenzhen asked, "What do you mean?"
Xiaojie said: "This is a point card game, and you have to deduct points for the game, and you can't go online when the points are deducted." ”
Wu Zhenzhen said: "How can you collect money? Isn't the Internet shared for free?"
Xiaojie said: "How to say it, there must be a certain amount of service for consumption." Overall, this World of Warcraft is a very good quality game, so I am willing to play it if he charges a fee. After all, this is much better than the "Legend" that my dad played back then. ”
After some exchanges, Wu Zhenzhen still didn't quite understand, after all, before this, in Wu Zhenzhen's heart, almost most of the functions of this Internet were free.
Whether it's playing Lianliankan or searching for data or something, it doesn't seem to have anything to do with the charge.
Xiaojie's paid game suddenly made Wu Zhenzhen look very dazed, and this charging method is also very troublesome, it seems that Wu Zhenzhen can't imagine what it is like to pay through the Internet at this time.
Although in the description of some articles in "Science Fiction World", various ideas such as fingerprint payment and face payment have been proposed.
However, in Wu Zhenzhen's view, these seem to take a long time to change with scientific and technological progress.
