Although "opening books is beneficial" is an idiom, I don't think it may be beneficial if you open books blindly.
Moreover, as the old saying goes, it is better to believe in books than to have no books and talk on paper.
Opening books may not be beneficial, and sometimes (if you read bad books) it will cause damage. As educator Xu Teli said, "It's no use reading books about your family." Most unhealthy things come from reading those bad books. The criminal facts of some teenagers in today's society are a good proof, that is, they are polluted by those bad books and periodicals, infected with bad hobbies, and finally embark on the road of illegal crimes.
Nowadays, students may all like to read martial arts and romance novels, books and periodicals, and sometimes forget to eat or sleep. Once they get lost in reading, they will be possessed. Then they concentrate on books in class and have no intention to study, and their grades will plummet. Others are attracted by some plots in the book, imitate the characters in the book, and sometimes take the road of crime. Isn't reading killing yourself? This is only the first layer of "opening books is beneficial": opening books is beneficial. And the second floor.
The second is that we should have a choice when studying. Don't read unhealthy books that don't help us much. When reading, you should read some books that are beneficial to your physical and mental health and helpful to your study and life. Such a book is a good book. Only by reading well will you not ruin yourself. Some people compare books to friends. If you value books, you will make good friends and make progress. If you don't read good books, of course, you will make friends with people who don't make good friends, and then you will regress. Because near Zhu Zhechi, near Mexico is black! Therefore, only reading will be beneficial to you. Therefore, in my opinion, opening books may not be beneficial. I sincerely hope that every student can read books selectively. Don't lead yourself astray and ruin your life just because you read a wrong book.
I don't think it is necessarily beneficial to open books. It is true that reading can make people increase their knowledge, cultivate their temperament and cultivate their body and mind, but "opening books" is only a necessary condition, not a sufficient condition.
Liu Xiang of the Han Dynasty once said: "Books are still medicine, and good reading can cure fools." Since books are medicine, they have two functions: first, good medicine will cure diseases; One is poison, which can kill people. Isn't it? In Germany in the 1920s, many people were regarded as Hitler's martyrs because of their bad influence on Mein Kampf. Bad books, like bad friends, may kill you. It's true. Now some students are addicted to martial arts or romance novels, reading those grotesque books all day, and "throwing" their homework aside, which leads to a decline in their academic performance, and finally draw water with a sieve. Just think, can a book like "Open" be said to be "beneficial"? "A good book is better than a treasure, and a bad book is worse than a robber." Therefore, whether it is beneficial to open a book depends on what volume to open first.
