For example:

1, China's cotton production is now more than self-sufficient. (The attributive and the head word are reversed and should be changed to "cotton production")

We should give full play to the role of young people. Put "Man" before "Play" and delete a "De".

Second, improper collocation.

For example:

1, spring breeze blows in waves, branches sway, moonlight and shadows shake together, making a rustling sound. If the subject and predicate are not properly matched, "moonlight" will not make a sound. )

Now that you are here, I should go, too. (Because "and" Ye "cannot be used together," Ye "should be changed to" Jiu ")

Third, the composition is incomplete or redundant.

For example:

1, Mr. Lu Xun created essays in the struggle and became a wonderful flower in literature and art (missing the subject, changing "creation" to "creation")

He sat there with rapt attention, listening to the teacher. (Redundant components, delete "absorbed" or "absorbed")

Fourth, the structure is chaotic.

For example, all the students said yesterday's activity was a pleasant day. (Delete one from "Event of" and "Date of")

Fifth, the meaning is unclear. (including ambiguous quotations and ambiguous sentences)

For example:

1, the director, deputy director and other bureau leaders attended the commendation meeting. (It is not clear whether the leaders of other bureaus are leaders of this bureau or leaders of other bureaus)

2. My sister is anxious when she can't find her parents. (What's the situation? Is "Sister" in a hurry? Or "dad" and "mom" are in a hurry. Or is "mom" in a hurry? You can put a comma between "Dad" and "Mom" or put a comma before "Dad".
