自行车— Part 1 评分报告

建议: Overall this answer is clear, relevant and contains useful details (color of bike, training wheels, routine, learning to balance). To improve further: 1) Correct minor pronunciation/word choice error (“bite” → “bike”). 2) Keep answers concise (aim for 3–4 sentences) — remove redundant phrasing like “which helped me” after you already mention building confidence and coordination. 3) Add one specific brief example or feeling to make it more vivid (e.g., where you learned or how you felt when you removed the training wheels). Also use a linking phrase to connect the supporting detail smoothly (e.g., “As a result,” or “After that,”).

示例: Yes, I had a bike. My parents bought me a small blue bicycle with training wheels, and I rode it every afternoon around the neighborhood. After a few weeks I learned to balance, and as a result I proudly removed the training wheels and felt very excited to ride on my own.

建议: Good content and specific reasons (cost, traffic, delivery workers, eco-friendly). To improve: 1) Watch register and avoid casual words like “super” — use “very” or “extremely” for a more natural formal tone. 2) Fix small grammar issues: include articles and hyphens where needed (“a cost-effective and practical way,” “a short commute,” “eco-friendly”). 3) Use linking words to structure your points (e.g., “Firstly,” “Additionally,” “Finally”). 4) Limit to 3–4 sentences and vary vocabulary slightly (e.g., “widely used” instead of repeating “use”).

示例: Yes, bicycles are very popular across my country. Firstly, they are a cost-effective and practical way to travel for short commutes to work or school. Additionally, delivery workers often prefer bikes because they are more maneuverable in congested streets, and finally, many people choose them because they are eco-friendly.

× Yes, I did have a bite.

✓ Yes, I did have a bike.

The student used the word 'bite' which is a misspelling or incorrect word for 'bike'. This is a vocabulary/spelling error rather than a grammar rule from the provided list; it most closely fits 'Sentence structure errors' because the sentence meaning is distorted. Suggestion: replace 'bite' with the correct noun 'bike' and proofread for similar typos.

× ...they are cost effective and practical way to travel.

✓ ...they are a cost-effective and practical way to travel.

The sentence is missing the indefinite article 'a' before the noun phrase 'cost-effective and practical way'. Also 'cost-effective' is a compound adjective and should be hyphenated when before a noun. Suggestion: include the article 'a' and hyphenate compound adjective.

× Many people use them to avoid traffic and reduce gas costs for short commute to work or school, and delivery workers often prefer bikes because they are faster and more maneuverable in congested streets.

✓ Many people use them to avoid traffic and reduce gas costs for short commutes to work or school, and delivery workers often prefer bikes because they are faster and more maneuverable in congested streets.

The phrase 'short commute' should be plural 'short commutes' because it refers to repeated trips made by many people; this is a singular/plural mismatch. Suggestion: make 'commute' plural to agree with 'many people' and the plural sense of repeated journeys.

× Moreover, they're eco friendly.

✓ Moreover, they're eco-friendly.

When 'eco-friendly' modifies a noun or stands as a compound adjective, it is standard to hyphenate it. Although informal writing sometimes omits the hyphen, hyphenation improves clarity. Suggestion: use 'eco-friendly' with a hyphen.
