It should be like this: Reviewing the past and learning the new can be a teacher. Knowing what you know is knowing what you don’t know. Learning without thinking is knowledge." Is it a mistake to think without learning? I hope it helps you. 1. You can become a teacher by reviewing the past. 2. I don’t know.

The answers above are all correct, I will just make a supplement.

Confucius’ famous saying about learning: Knowing is knowing, not knowing is not knowing, and I am not the author because I don’t know. Yes. If you learn a lot, you will choose the good ones and follow them. If you know a lot, I will not be tired of learning. Ask about the incompetent, ask too much about the few; if there is nothing, what is true is false, and make mistakes without correction. . If you don't get angry or angry, if you don't respond in three ways, you will never be better than a good person, and a good person will be better than a happy person. Thinking is useless, it is not as good as learning. Learning without thinking is useless, thinking without learning is dangerous. Those who are evil must be inspected; those who are good must be inspected. Isn’t it true that one should learn and practice it from time to time? If you review the past and learn the new, you can become a teacher. The sun knows where he is dead, the moon has not forgotten what he can do, and he is said to be eager to learn. If you don’t learn poetry, you won’t be able to express it. Poetry can be exciting, watchable, group-building, and resentful. Those who are near serve the father, those who are far away serve the king; they are more familiar with the names of birds, beasts, grass and trees. Human beings have no permanence and cannot be witch doctors. There is no distinction between education and distinction. I have done nothing but restrain myself, and I have not yet learned anything.

If you learn without thinking, you will be lost; if you think without learning, you will be in danger
