/kloc-in 0/7, there was a volume of literature, history and geography synthesis in China. I think this year is very strange, and the style of the previous questions is different. It is increasingly biased towards subjective understanding, or its answer does not depend on textbooks. Although it is generated from textbooks in theory, it is not absolutely related to textbooks, and depends largely on students' own independent analysis and material refining. The difficulty has increased a lot invisibly, which leads to the unsatisfactory comprehensive literature performance this year, which is lower than the normal level 10, or 20 or even higher.
