Headphones— Part 1 채점 보고서

제안: Be concise and correct grammatical errors. Begin with a clear topic sentence, avoid repetition, and use linking words to clarify sequence (e.g., 'so', 'therefore'). Use specific details (when, why) in one or two supporting sentences. Correct tenses and remove duplicated phrases.

예시: I don't use headphones much anymore. I used to wear them when I commuted to high school, but one day they died because I forgot to charge them, so I switched to earphones which are more convenient and portable.

제안: Directly answer the question about the type and avoid incorrect words ('hats') and grammar errors ('was high performance'). Start with the model/brand, then add one specific reason using a linking word (e.g., 'because' or 'as'). Limit to two or three sentences.

예시: I mainly used Sony over-ear headphones when I needed them. I chose Sony because they were comfortable and had excellent sound quality, which made listening more enjoyable.

제안: Start with a clear time or situation, avoid unclear phrases ('worry them a lot'). Use one linking phrase to provide reason or effect. Be specific about occasions and keep it concise.

예시: I usually used headphones while commuting to school. I listened to my favorite music on them because their excellent sound quality made trips more enjoyable.

제안: Good content and clear reasons. Improve by making tense consistent and using a linking word to contrast (e.g., 'however' or 'so'). Be slightly more specific about study tasks to strengthen the response.

예시: I don't use headphones when I'm studying because I find it hard to concentrate while listening to music. For example, when I need to read or solve math problems, I prefer a quiet environment to focus fully.

제안: Clear and balanced answer. Fix minor errors ('walk Walking') and tighten sentences using linking words ('however', 'for example'). Add one brief specific condition to show awareness of safety or comfort trade-offs.

예시: I think headphones are comfortable because they block out noise and let you enjoy music privately. However, they can be dangerous when walking on busy streets since you might not hear traffic, so I avoid using them in that situation.

× I used to wear them when I was in high school while commuting, but once I was really frustrated after forgot after forgetting to charge them.

✓ I used to wear them when I was in high school while commuting, but once I was really frustrated after forgetting to charge them.

The sentence contains redundant and incorrect verb forms 'forgot after forgetting'. The correct form is 'after forgetting' to indicate the reason for frustration. Use the -ing form after 'after' to show a completed action that caused the frustration. Suggestion: remove the extra 'forgot' and keep 'after forgetting'.

× So I switched to earphones because they are more convenient and easier to carry out.

✓ So I switched to earphones because they are more convenient and easier to carry.

The verb phrase 'carry out' is incorrect here; it means 'perform' rather than 'carry with you'. Use the verb 'carry' to indicate portability. Also ensure pronoun 'they' correctly refers to 'earphones' which is fine.

× To be honest, I rarely use hats for now, but I used to wear them a lot in high school.

✓ To be honest, I rarely use headphones now, but I used to wear them a lot in high school.

The student wrote 'hats' likely by mistake for 'headphones'. This is a word choice error rather than a grammar rule from the list, but it affects meaning. Replace 'hats' with 'headphones'. Also change 'for now' to 'now' for natural phrasing.

× I remember asking my mother to buy a pair of Sony headphones because they were comfortable and was high performance.

✓ I remember asking my mother to buy a pair of Sony headphones because they were comfortable and had high performance.

The clause 'they were comfortable and was high performance' has incorrect verb agreement and adjective usage. The subject 'they' requires the plural verb 'were' or another appropriate verb. Use 'had high performance' or better 'had high performance' or 'performed well'. Suggestion: 'because they were comfortable and performed well.'

× I loved it.

✓ I loved them.

The pronoun 'it' refers to a singular noun but 'headphones' is plural. Use 'them' to refer to a plural noun.

× I rarely use headphones now, but I worry them a lot.

✓ I rarely use headphones now, but I wore them a lot.

The student likely intended 'wore' (past of wear) rather than 'worry'. 'Worry' is incorrect and makes no sense in context. Use 'wore them a lot' to express past habit.

× When I was in high school while commuting to school, I used them to listen to my favorite music because they had excellent sound quality which made the trips more enjoyable.

✓ When I was in high school, while commuting to school I used them to listen to my favorite music because they had excellent sound quality, which made the trips more enjoyable.

The sentence is mostly correct but needs commas for clarity. No major grammar type from list except punctuation; nonetheless ensure clause order is natural: separate 'When I was in high school' and 'while commuting' for clarity.

× I enjoy listening to music with headphones, but I don't use them when I'm studying because I found it quite hard to focus on more than one thing simultaneously.

✓ I enjoy listening to music with headphones, but I don't use them when I'm studying because I find it quite hard to focus on more than one thing simultaneously.

The sentence mixes present ('don't use') with past 'found'. Maintain present tense 'find' to match the habitual situation. Suggestion: keep tense consistent for general truths or habits.

× When I need to concentrate, I prefer a quiet environment to focus on myself.

✓ When I need to concentrate, I prefer a quiet environment to focus.

The phrase 'focus on myself' is awkward here; 'focus' or 'concentrate' suffices. Removing 'on myself' makes the sentence natural and clear.

× For example, using headphones while walk Walking in busy streets can be dangerous because you might not hear traffic.

✓ For example, walking in busy streets while using headphones can be dangerous because you might not hear traffic.

The original contains duplication ('walk Walking') and incorrect verb form after 'while'. Use the gerund 'walking' and order the phrases so 'walking ... while using headphones' or 'using headphones while walking' are both acceptable. Suggestion: 'Using headphones while walking in busy streets can be dangerous' or the corrected version above.
