(1) Incomplete components: This sentence lacks necessary components and its meaning is incomplete. For example, "Sing loudly." Students know that a sentence can be divided into two parts. The former part says "who" or "what" and the latter part says "what", "what to do" or "how to do it", which is the basis of the sentence.
(2) Repetition of meaning: This kind of sentence means saying a meaning in front, repeating it later and repeating the meaning. For example, "I corrected the incorrect typo." The meaning of "incorrect" and "typo" here is the same, and it is redundant to use them together.
(3) Improper use of words: This kind of sentence is due to unclear understanding of the meaning and misuse of synonyms, which violates the structural rules of the sentence. For example, "the students warmly welcome the new teacher." The word "enthusiastic" means: enthusiastic, interested and willing to do my best, so it is obviously inappropriate to use it in front of "welcome"
(4) Word order inversion: Word order is the order of words in a sentence, reflecting the position of words in the sentence structure. Every word has its specific position in the language structure. If you leave your position, you will make mistakes in improper word order. For example, "this year's wheat harvest is in sight and the growth is gratifying." The growth of wheat is gratifying, the harvest is in sight, and the inversion of word order does not conform to the objective law.
