There are three common explanation orders, namely, temporal order, spatial order and logical order. Temporal order is developed according to the order of time development, spatial order is developed according to the order of inside and outside, far and near, high and low of space, and logical order is developed according to the logical internal relations.
The chronological order is mainly based on the chronological order. The common chronological order includes history, season, age, etc. For example, in the article "Language of Nature", the first paragraph is written in chronological order, first in the beginning of spring, then in the hot summer, then in the autumn, and finally in the cold winter, which is typical of writing in the order of four seasons.
The spatial order is from inside to outside, from far to near, from high to low, from top to bottom, from left to right, from whole to part, from front to back, etc. For example, in the language of nature, the longitude factors that affect phenology are written in the spatial order of offshore and coastal areas.
The logical order is mainly based on the internal essential relationship of things. The common logical order is causal order, primary and secondary order, total score order, from outside to inside, from complex to simple, from special to general, from phenomenon to essence, etc. For example, the Dead Sea never dies, the language of nature, marching into the desert, etc., all of these articles use logical order to explain.
There are many methods of explanation. Students should not stick to the above methods of explanation. They should take into account the order of time and space, the internal logical relationship between things, etc., and choose the most suitable order of explanation according to the object of explanation, so as to make a clear explanation.
