Incomplete composition: refers to a kind of ill sentence in which the sentence is incomplete and lacks a certain composition, which makes the meaning of expression unclear. Common types of "incomplete components" are: missing subject, missing predicate, missing object and missing necessary modifiers.

Improper use of words: due to unclear understanding of the meaning, it is easy to use improper words in the scope of meaning, praise and criticism, especially synonyms and related words, resulting in sick sentences. For example, "he does things calmly and arbitrarily." "Arbitrary" is a derogatory term, which should be changed to "decisive" if used improperly.

For example, we should help small students with an open mind. Analysis: The usage of "modesty" is wrong and should be changed to "patience" to help primary school students.

Improper collocation: it is mainly manifested that the predicate cannot state the subject, sometimes the subject or predicate acts as a coordinate phrase, and some collocation is improper.

For example, the improvement of local ecological environment can not curb the overall deterioration, and the speed and area of land desertification in China are still expanding every year. Analysis: "speed" cannot be "expanded", and multiple subjects and a single predicate cannot be completely matched.
