What are the characteristics of classical Chinese

1、 From Han and Wei dynasties to Ming and Qing Dynasties, due to the official implementation and the need of the imperial examination, classical Chinese was formed on the basis of the spoken language of the pre Qin Dynasty, Scholars deliberately imitate the language of "four books and five classics" to write poems and articles, which is ancient and elegant. In this way, classical Chinese, as a written language, is more and more far away from the actual spoken language, resulting in the separation of language and writing
2、 Before the May 4th movement, classical Chinese, as the dominant written language, was passed down from generation to generation, and its linguistic elements remained unchanged. For example, some basic sentence patterns and the usage of commonly used function words in the pre Qin period were preserved in classical Chinese, even the most active vocabulary in the three elements of language, In classical Chinese, it also has a strong stability: the ancient meanings of some words have long disappeared in spoken language, but they are still used in classical Chinese. Although it is inevitable for later generations to mix some of the spoken language at that time in imitation, thus bringing some subtle changes to classical Chinese, but on the whole, classical Chinese basically maintains its original appearance in terms of vocabulary system and grammar system
3、 In ancient China, most of the important books were written in classical Chinese, and many of the immortal works are famous for their simplicity and conciseness. It can be said that classical Chinese itself contains succinct factors: first, monosyllabic words are dominant in classical Chinese, while disyllabic words and polysyllabic words are relatively few; second, classical Chinese is mostly omitted, It is very common to omit the subject, object, predicate and preposition. In addition, the famous writers of the past dynasties paid more attention to tempering the language and stressed "micro words and broad meanings", so they formed the strict and concise style of classical Chinese
4、 Ancient Chinese is hard to understand. Because of the age, classical Chinese, which is separated from spoken language, is becoming more and more difficult to understand Therefore, it has always been one of the hard work for scholars to annotate ancient books and solve difficult problems

When Xiao Ming solves the system of equations {cx-7y = 8, he gets {y = 2} by misreading C, and the correct solution is {y = - 2
4 in the equation y-3x = 2, if y is expressed by an algebraic expression containing x, then (); if y is expressed by an algebraic expression containing y, then ()

It is known that {y = 1 and {y = - 5 are two solutions of the quadratic equation y = KX + B with respect to X and y, then k = (), B = ()
3x-8y=-9,(1)
When we use the substitution method to solve the binary linear equations {x-2y = 3 (2), the best first step is to transform the equation () and express it with an algebraic formula containing (), and then substitute it into the equation（
The following equations are solved by substitution elimination method

Solving ten practical problems of binary linear equations

1、 There is a pasture where grass grows at a constant speed every day. If 24 cattle are grazed, grass will be eaten in 6 days. If 21 cattle are grazed, grass will be eaten in 8 days. Suppose the amount of grass eaten by each cattle is equal. Question: 1. If 16 cattle are grazed, how many days can grass be eaten
