Now the main tool of our writing is the computer, and if there is any error, it is better to correct it directly on the computer. Back when I was studying, humming and writing on exam papers and homework papers, if I wrote wrong... It's really a disaster to change it.
Do you remember the modification methods that you used when you were studying?
1. Eraser + saliva
Cleanliness: ★★★ ☆☆
Paper injury risk: ★★★ ☆☆
Popularity: ★★★★★
Applicable people: 8 years old or older.
Directions for use: Follow your doctor's advice if you have mouth ulcers and gingivitis.
In 1770, the British scientist Priest discovered that rubber, a substance that can easily erase the handwriting of the pencil, was overjoyed, because this discovery could save a lot of bread from the water and fire that erased the pencil handwriting. That's right! Before the eraser was invented, bread crumbs and sponges were used as erasers. These two destroy the paper, not to mention, and can not be wiped clean at all! It was not until 1839, when erasers in the modern sense were thoroughly invented, that bread and sponges were completely retired from the stage of history of pencil handwriting!
But when the erasers came to prominence in their areas of work, they found themselves working overtime in addition to being responsible for pencil handwriting! Then be taken to wipe pens, ballpoint pens, etc.! And you won't be lonely on the way to overtime! Eraser always found his other partner – saliva.
But The eraser himself was not happy about it—the faint stench was a spiritually eternal and unbearable injury.
2. Blade
Cleanliness: ★★ ☆☆☆☆
Paper injury risk: ★★★★ ☆
Popularity: ★ ☆☆☆☆☆
Suitable for: 12 years old or older.
Advice for use: Not recommended for upset people.
In addition to the doctor's lancet, the most delicate and complex blades in the world are blades that make a living scraping typos! When mankind's first stone knife was made by hammering, it must not have thought that its descendants would be responsible for scraping off typos so delicately in ten thousand years.
I still remember that it was a 10-year-old and 4th grade class, and the Chinese teacher said that from now on, I could no longer write homework with a pencil, but I should use a pen or ballpoint pen. A big question rose up from the editor's heart - so, what is the typo?
The Chinese teacher helped his eyes, and suddenly raised a 3-centimeter-long blade with a cold light from the podium and said lightly: "Scrape with it." ”
After several unsuccessful exercises, the impatient xiaobian took the blade and cut it fiercely against his homework book, at this time there was a regular brushing and brushing sound in his ears, and looked back: the same table was steadily scraping typos one by one, the scene was silent, and the human knife was one...
The 4th grade editor knew one thing at that moment - people and people are absolutely different.
3. Correction sticker
Cleanliness: ★★★★ ☆
Paper injury risk: ★ ☆☆☆☆☆
Popularity: ★★ ☆☆☆☆
Suitable for: 5 years old or older
Advice for use: Use better for people with obsessive-compulsive disorder.
Self-adhesive is an American invention, but cut it into small pieces as a student correction sticker to use, but in history it is difficult to find the trace of its inventor, not to mention the patent registration order so that we can trace the date of its birth, on the above two points to speculate, Xiaobian believes that this innovation should be attributed to our Chinese.
Since its inception, the correction sticker has benefited countless people who are as stupid as Xiaobian - just a gentle tear and a gentle paste, all errors can be covered, greatly improving the efficiency of writing homework.
With the correction sticker and no longer using saliva and blades, Mom no longer has to worry about holes in my homework book!
However, because the price of each package of corrected stickers is 5 cents and 5 pieces, many students are really unable to bear this huge amount of money, and the popularity has dropped slightly...
4, revised liquid
Popularity: ★★★ ☆☆
Applicable people: those who have opinions about teachers.
Advice for use: It is best for users to wear a mask.
Correction liquid as a way to remove handwriting is not very popular, but it does satisfy many little girls without nail polish... However, the correction liquid is not only for this group, many students with fantastic ideas have pushed its use to new heights.
Because the composition of the correction liquid is more complex and accompanied by a pungent odor, many students only need to open a lazy egg-like squeamish after using the correction liquid, and accompanied by a weak raise of the hand, tell the teacher that they have nausea, vomiting, dizziness, headache and other symptoms, and tell the teacher that it is likely to be due to the use of inferior correction liquid, generally you can take sick leave to go home... Some students, after really buying inferior correction liquid, adhering to the spirit of saving glory and must be used up, increase the amount of use in the homework books of teachers who are dissatisfied with themselves, so that some teachers do have the above symptoms.
Therefore, when using the correction liquid, you must consider the health of yourself and others before deciding whether to use it.
5. Adhesive tape
Popularity: ★★★★ ☆
Applicable people: people with more work.
Usage advice: Not suitable for multiple modifications.
In 1928 in St. Paul, Minnesota, USA, Richard Drew invented scotch tape, tape originally appeared to glue things, during the Great Depression in the United States, people found hundreds of ways to use this tape, from mending clothes to protecting broken eggs It has great uses...
However, under the educational policy of Chinese sea tactics, Guangdong University students found that it was not good to stick things with it, but it was very quick and quick to correct the mistakes on paper!
Because not all students have the habit of carrying scissors with their hands, many times students can only use their teeth to bite off the tape after using the tape, in the process of biting the tape day after day, many students have developed a solid masseter muscle, directly laying a solid foundation for them to open food bags and open wine bottles with their teeth later...
However, this correction method is not suitable for use in the state of impatient writing, because in the case of uncontrollable force, it is likely to stick hundreds of words just written together...
6. Standard modification symbols
Cleanliness: ★ ☆☆☆☆☆
Suitable for: People who take important exams
Suggestion: It is best not to use it easily for those who have confused logic
【Correct Pattern for Correcting Written Errors】
The modified symbols of the standard are really put into practical use, generally before the college entrance examination... Before that, the above four ways alternated in turn.
However, in the official examination, only the standard modification symbols can appear, and many students have to adapt as soon as possible before the big exam.
This method of correcting written errors will encounter some problems when it is put into use. It often happens that I write the beginning of a 200-word essay, suddenly feel that it does not conform to my main idea, draw a circle directly to a long paragraph, and then completely discard it.
This choice still requires courage and determination...
