영어 작문 연습-AI-powered English writing feedback

Example

A user is asked to translate the sentence '나는 어제 숙제를 끝냈다.' and translates it as 'I finish my homework yesterday.' The system will explain that the past simple form ('finished') should be used because the action is complete and took place at a specific time in the past.

Scenario

This feature is designed for learners who struggle with choosing the right tense. It is particularly useful for intermediate students who often mix up past, present, and perfect tenses due to differences between Korean and English temporal structures.

Example

A user translates '만약 내가 시간이 있다면, 나는 여행할 것이다.' as 'If I have time, I will travel.' The system will suggest a more natural translation: 'If I had time, I would travel,' explaining the use of the past subjunctive to express an unreal condition.

Scenario

This function is ideal for advanced learners, as the subjunctive mood is a challenging aspect of English grammar for Korean speakers. The feature focuses on providing clear distinctions between real and hypothetical conditions, which is often difficult to grasp in English.

Example

A user may translate '나는 학교에 갔다.' as 'I went to school in bus.' The system will point out that the correct preposition is 'by' in this case ('by bus') and explain the differences between 'in' and 'by' when describing transportation.

Scenario

Prepositions in English often differ greatly from their Korean counterparts, which can confuse learners. This feature helps users understand the nuanced uses of prepositions, which are essential for achieving fluency in English.
