1. This is my homeroom teacher, Mr. Seo. He is a Chinese letters teacher. He is very generous.
2. This is my homeroom teacher, Mr. Choe. He is a M.E. teacher. He is strict.
3. This is my homeroom teacher, Mr. Choe. He is a ME teache. He is strict.
4. This is my homeroom teacher, Mr. Choe. He is a moral education teacher. He is strict.
--------------------------
Are they all suitable? Which one can we use among 3, 4, and 5?
1 and 4 are correct.
You need to use "an" before an abbreviation like "M.E."
Ex:
He is an M.E. teacher.
Based on the given description, there are a few errors in the sentences you provided. Let's correct them one by one:
1. This is my homeroom teacher, Mr. Seo. He is a Chinese literature teacher. He is very generous.
2. This is my homeroom teacher, Mr. Choe. He is an M.E. (Mechanical Engineering) teacher. He is strict.
3. The third sentence should be omitted as it is a duplicated version of sentence 2.
4. This is my homeroom teacher, Mr. Choe. He is a moral education teacher. He is strict.
Now, among the corrected sentences (1, 2, and 4), they are all suitable descriptions, but the choice depends on the specific subject or type of teacher you want to mention.
- Sentence 1 describes Mr. Seo as a teacher of Chinese literature who is generous. Use this if Mr. Seo teaches Chinese literature.
- Sentence 2 describes Mr. Choe as a mechanical engineering teacher who is strict. Use this if Mr. Choe is specifically a mechanical engineering teacher.
- Sentence 4 describes Mr. Choe as a moral education teacher who is strict. Use this if Mr. Choe teaches moral education.
So, the appropriate sentence to use depends on the subject or type of teacher you want to mention.
