4. From the perspective of historical materialism, how to understand and evaluate Jing Ke's assassination of the king of Qin? Pushing Jing Ke gently to stab the king of Qin is a just move against rape. His spirit of not being afraid of violence, sacrifice and danger is commendable. Qin's unification of the six countries is the trend of historical development, which cannot be changed by the wishes of individuals or a few people. Jing Ke didn't understand that it was difficult to reverse the decline by one person, and he didn't understand that the unification of the Qin Empire was an inevitable trend of historical development, so he could only end in tragedy. Jing Ke stabbed the king of Qin, and the struggle against negative factors in the process of historical development was reasonable. As far as the whole historical development process is concerned, it has great historical limitations. First of all, the central theme of the article mainly describes the complete process of Jing Ke's assassination of Qin Wang from preparation, implementation to final failure. In the order of time and events, the heroic images of resisting violence, helping the weak to save the country, being brave and calm, and dying are vividly reproduced, which shows the author's thought of resisting violent rule. Second, the writing characteristics 1. Good at writing characters through contradictions and conflicts. For example, Taizi Dan and Jing Ke are expressed in the context of Qin Yan's contradiction; Jing Ke is portrayed through his conflict with Taizi Dan. Finally, Jing Ke's character was shaped by a sharp struggle with the king of Qin. These contradictions, conflicts and struggles all provide space for the performance of the role, which has strong drama and tension. 2. Vivid dialogue and expression description. In the dialogue between Jing Ke and Fan, Jing Ke first provoked Fan's hatred of Qin with words, and then asked Fan what to do in the face of such a deep hatred. Then, in view of the saying that "I don't know what I'm talking about", he tentatively put forward a plan that can not only avenge Fan, but also save Yan, layer by layer. As a result, Fan plausibly committed suicide. When he met the king of Qin, "Qin Wuyang became surprised" and "Jing Ke smiled at Wuyang" and explained to the king of Qin. At this critical juncture, a calm attitude and appropriate words eliminated the crisis. These dialogues not only show the gradual development of the situation, but also describe Jing Ke's delicacy and composure, taking his time at the critical moment and improvising.
