The sick sentence is: "Under the teacher's education, he made clear his learning attitude."

"Clear" means clear and definite, which can't be matched with "learning attitude", while correct means "making xx's attitude correct", which can be matched with "learning attitude".

This sentence should be revised to: "With the teacher's education, he corrected his learning attitude."

Modification of common sick sentences

1, incomplete composition.

Is that the sentence is incomplete. After reading two poems by revolutionary martyrs, I received a profound education. Who is deeply educated? Didn't say it. This sentence should be supplemented by words like me or my classmates.

2. Improper collocation.

That is, the main component of the sentence, the additional component and the main component do not match well. Suzhou in spring is the most beautiful season of the year. After shortening this sentence, we can see that Suzhou is a season, which obviously doesn't make sense. As long as spring in Suzhou is the most beautiful season of the year, it will be smooth sailing.

3. Inconsistent.

A word must be reasonable and not contradictory. I have basically finished all my homework. Homework is either basically finished (a little left) or completely finished (nothing left). It is obviously contradictory to say basic and complete, and only one of the two statements can be retained.
