Traffic— Part 1 채점 보고서

제안: Your answer is clear, relevant and gives a specific example, which is good. To improve, make the response slightly more concise and add a linking phrase to connect the example and the reason more smoothly. Also vary vocabulary (e.g., use 'pedestrian crossings' or 'foot traffic') and avoid repeating ideas (you mention many crosswalks and then explain busy streets — combine these). Keep to under five sentences.

예시: Yes. I live in Shenzhen, and there are many pedestrian crossings near my home because the area has a large shopping mall and a subway station about 500 meters away. As a result, foot traffic is heavy, so clearly marked crossings are necessary for safety and to help people cross quickly.

제안: This is a well-structured, concise response that directly answers the question and provides reasons. To further improve, add a small contrast or minor improvement suggestion to show critical thinking (for example, mention occasional congestion or cyclist safety) and use a linking word such as 'however' or 'although' to introduce it. Also try to replace repeated words like 'well timed' and 'reasonable' with synonyms for variety.

예시: Generally, traffic control in my area is very efficient because the traffic lights are well timed and waiting times are reasonable. However, I would improve cycle lanes and rush-hour management slightly, since congestion can still occur near the subway station during peak times.

× For example, there is a big shopping mall and a subway station about 500 meters from my apartment, so the streets are busy and the pedestrians need clearly marked crossings for safety.

✓ For example, there is a big shopping mall and a subway station about 500 meters from my apartment, so the streets are busy and pedestrians need clearly marked crossings for safety.

This sentence includes an unnecessary definite article before 'pedestrians'. Using 'the pedestrians' incorrectly specifies a particular group, but in this context general pedestrians are meant. This is an article/pronoun choice issue related to noun reference (Grammar Problem Type ID 12 and 22). Suggestion: remove 'the' to make it 'pedestrians need' so the sentence refers to people in general and reads more naturally.

× The traffic lights are well timed so waiting times are reasonable, and there are clearly marked crossings that separate vehicles from pedestrians which makes it safe to cross the road.

✓ The traffic lights are well timed, so waiting times are reasonable, and there are clearly marked crossings that separate vehicles from pedestrians, which make it safe to cross the road.

The relative clause 'which make it safe' refers to 'clearly marked crossings' (plural), so the verb should be 'make' not 'makes'. This is a subject-verb agreement error (Grammar Problem Type ID 27). Also add a comma before 'which' to separate the nonrestrictive clause. Suggestion: use 'which make' to match the plural subject and improve clarity.
