The short sentences of Confucius' famous words in the third grade are as follows:

1. Learn from time to time, isn't it? Is it not delightful to have friends coming from distant quarters? Is he not a man of complete virtue, who feels no discomposure though men may take no note of him? -pre-Qin Confucius and his disciples

Translation: Isn't it pleasant to learn (knowledge) and then review it at a certain time? Isn't it happy to have like-minded people coming from afar? People don't understand (me) and (me) are not angry. Aren't they also morally cultivated people? "

2, review the past and learn new things, and you can be a teacher. -pre-Qin Confucius and his disciples "The Analects of Confucius for Politics"

Translation: If you review what you have learned, you can gain new understanding and experience from it, so you can become a teacher by virtue of this.

3. Learning without thinking is useless, and thinking without learning is dangerous. -pre-Qin Confucius and his disciples "The Analects of Confucius for Politics"

Translation: Just learning without thinking will make you feel confused and at a loss. Just dreaming without learning will make your heart full of doubts and opinions.

4. Those who know are not as good as those who are good, and those who are good are not as happy as those who are happy. -Pre-Qin Confucius and his disciple "The Analects of Confucius Yong Ye"

Translation: People who know how to learn are not as good as those who like to learn; People who like learning can't compare with those who enjoy learning.

5. In a threesome, there must be a teacher. Choose the good and follow it, and change the bad. -Pre-Qin Confucius and His Disciple "The Analects of Confucius"

Translation: Many people walk together, and one of them must be my teacher. I choose his good aspects to learn from him, and correct my shortcomings against myself when I see his bad aspects.
