The academic speech environment is much better now than in the past, but there is a strange cynicism among intellectuals, who dare not speak out of their own ideas, lest they offend anyone. The reason for this is that some people were afraid in the past. Some are timid, but in the academic world, if you don't tell the real problem and look at your face, you won't be able to do science or research. The most appropriate summary of the main meaning of this text is:. ['Dare to challenge authority.', 'No bones can not become academics.', 'Dare to express your own thoughts to learn well.', 'The academic environment is an important factor affecting academic achievement.']
