1. As the British writer Fielding said: "Bad books are like bad friends, they may kill you." If you understand "opening a book is beneficial" one-sidedly and read all books, Regardless of the content, reading it will be beneficial, but this is not right! We must learn a skill to choose the most valuable and enlightening books that are suitable for ourselves to read.

2. Believing in books is worse than having no books at all

3. Talking about war on paper, Zhao Kuo was defeated and killed in the Warring States Period

4. Reading thousands of books is not as good as traveling thousands of miles.

5. Ma Su of the Three Kingdoms was also well-read in the art of war, but he exaggerated, which led to the loss of the street pavilion.

The idea of ????refuting (leave yourself a way out, and at the same time prove that your point of view is correct)

Although "opening the book is beneficial" is an idiom, but I think: if you blindly open the book, Not necessarily beneficial.

Opening a book is not necessarily beneficial, and sometimes (if you read bad books) it will cause damage. As the educator Xu Teli said: "Relevant people often read books, which is not beneficial to the body and mind." It is not beneficial to the body and mind. Most of my problems come from reading those bad books. The fact that some teenagers commit crimes in today's society is a good proof that their minds have been polluted by those bad books and periodicals, and they have become infected with bad habits, which eventually leads them to commit crimes.

Nowadays students may like to read novels and books about martial arts and romance, sometimes to the point where they forget to eat and sleep, and can’t let go of the books. Once they are obsessed with reading a book, they will become obsessed with it, and they will only focus on it in class. If you are thinking about books but not studying, your grades will plummet. There are also people who are attracted by some of the plots in the book, imitate the characters in the book, and sometimes turn to the path of crime. Isn’t this reading a book that is harming yourself? This is just the first layer of “opening the book is not necessarily beneficial”: opening the book is not necessarily beneficial. There is also a second level.

The second is that when we read books, we must have choices. Don’t read books that are unhealthy and won’t help us much. If you want to read, read some books that are good for our physical and mental health, and helpful for our study and life. Such books are good books. As long as you read good books, you will not ruin yourself. Some people compare books to friends. If you read a good book, you will make good friends, and you will make progress; if you read a bad book, you will certainly make bad friends, and you will regress. Because those who are close to vermilion are red, and those who are close to ink are black! Therefore, only reading good books will be beneficial to you. Therefore, my point is: opening the book is not necessarily beneficial. I sincerely hope that every student can have a choice in reading. Don't lead yourself astray and ruin your life just because you read the wrong book.

I don’t think opening the book is necessarily beneficial. It is true that reading can increase people's knowledge, cultivate their temperament, and cultivate their body and mind, but "opening the book" is only a necessary condition for "benefit", not a sufficient condition.

Liu Xiang of the Han Dynasty once said: "Books are like medicine, and reading them well can cure stupidity." Since books are medicine, they have two functions: one is good medicine, which can cure diseases; the other is poison, Put people to death. Isn't it? In Germany in the 1920s, many people saw Hitler's "Mein Kampf" and were adversely affected by it, saying that they were buried in Hitler's grave. "A bad book is like a bad friend, it may kill you." It’s not false at all. Nowadays, some students are obsessed with martial arts or romance novels. They read those weird books all day long and “throw away” their homework, which leads to a continuous decline in academic performance and finally results in a failure to draw water from a bamboo basket. All in vain. Just think about it, can "opening" such a "volume" of a book be said to be "beneficial"? "A good book is better than a treasure, and a bad book is worse than a robber." Therefore, whether opening a book is beneficial depends on what kind of book you open.
