Analysis of test questions: This question mainly examines students' ability to solve problems by using what they have learned. "Anti-Qing Restoration" shows the ideological connotation of the boxer movement against the autocratic rule of the Qing government, but the slogan obviously has historical limitations; The slogan of "eliminating foreign countries" embodies the anti-imperialist and anti-feudal revolutionary nature of the Boxer Rebellion, which is historically progressive. The slogan "Help the Qing Dynasty to destroy the foreign countries" is a pragmatic revolutionary proposition put forward on the premise that the imperialist aggression has deepened and the contradiction between imperialism and the Chinese nation has become the main contradiction in society, which has historical progress. Therefore, the three slogans show that the understanding of the Boxer Rebellion is constantly improving, and the answers are A and B C D, which is wrong and does not conform to the historical facts of the development of the Boxer Rebellion.

Comments: Regarding the influence of foreign powers' invasion of China on China in modern times, traditional historiography emphasizes the damage of foreign powers to China from the perspective of revolutionary historical view. In recent years, with the introduction of modern historical view and the deepening in Chinese mainland, more people think about this issue from a newer perspective, and the college entrance examination has also been introduced in time. While paying attention to the patriotism of the Boxer Rebellion, we should also see that it hinders the historical process of China's modernization.
