(1) If there is a case without a license, the case will be used instead of the certificate.
Because argumentative essays demonstrate arguments by enumerating limited examples, it is necessary to analyze and expound the close relationship between these examples and arguments in order to achieve the effect of "drawing inferences from others". Some candidates don't understand this point, or can't find the starting point to analyze the relationship between cases and arguments, and often come to an abrupt end after listing cases, taking examples as the basis; There are also some candidates who list more than N similar examples without analysis and summary in order to win with rich examples, which will only make people feel that the author is piling up materials instead of writing argumentative papers.
(2) The example is not typical
As mentioned above, argumentative essays demonstrate arguments by listing limited examples. "Limited" means that the cited examples must be representative and typical. The so-called "typical" is that this case has both certain social characteristics and distinctive personality characteristics. Otherwise, it is difficult to achieve the demonstration effect of "taking one as ten". It is true that the premise of choosing a typical case is to have a rich material reserve, but most of the current candidates do not pay much attention to accumulating new materials every day, nor do they pay attention to comprehensively interpreting existing materials with new ideas. Therefore, Qu Yuan, Li Bai, Du Fu, Edison and Hawking are "very busy", and it is inevitable that they will have aesthetic fatigue if they are used together.
