自行车— Part 1 评分报告

建议: Be more concise and correct small errors. Start with a clear topic sentence, then add one specific detail using a linking word. Correct grammar (e.g., "run a bike" -> "rent a bike," tense consistency: "needed"). Avoid extra clauses that make the sentence awkward.

示例: No, I didn't have a bike when I was a child. However, there was a convenient public bike‑sharing system in my city, so I could rent a bike whenever I needed to go somewhere.

建议: Improve grammar, repetition and coherence. Use a clear topic sentence, then add two specific supporting reasons linked with words like "because" or "for example." Fix plural and article errors ("bikes are," "short distances," "a cheap, convenient option"). Remove repeated words.

示例: Yes, bikes are very popular in my country because they are a cheap and convenient way to travel short distances. For example, many people ride bikes to reach the subway station since cycling is often faster than walking in crowded areas.

× No, I didn't have a bike when I was a child, but in China there was an easy to use public bike sharing system so I could run a bike whenever I need one.

✓ No, I didn't have a bike when I was a child, but in China there was an easy-to-use public bike-sharing system so I could rent a bike whenever I needed one.

Errors: 'easy to use' needs hyphens as a compound adjective before a noun (style) and counts as adjective formation (not in the list but corrected for clarity); 'bike sharing' commonly hyphenated as 'bike-sharing' when used as a compound noun modifier (style); 'run a bike' is incorrect verb choice — the correct verb is 'rent' (lexical error) and fits the context; 'need' should be past tense 'needed' to match the past time frame established by 'was' and 'didn't have'. Suggestion: use consistent past tense for actions in the past, choose correct verbs (rent rather than run), and use hyphens for compound modifiers before nouns.

× Yes, bike are very popular in my country.

✓ Yes, bikes are very popular in my country.

Error: 'bike' (singular) with 'are' (plural verb) is a subject-verb agreement issue. The noun should be plural 'bikes' to match the plural verb 'are' or change verb to 'is' if singular was intended. Suggestion: ensure number agreement between subject and verb; here plural 'bikes' matches 'are'.

× Many people use them to commute short distance, for example to reach the subway station.

✓ Many people use them to commute short distances, for example to reach the subway station.

Error: 'commute short distance' is ungrammatical; the correct phrase is 'commute short distances' (plural) or 'commute a short distance'. This is a prepositional/quantifier phrasing issue. Suggestion: use 'commute short distances' for a general statement or 'commute a short distance' for a singular instance.

× Because bike is a cheap cheap and often faster than walking in crowded area.

✓ Because bikes are cheap and often faster than walking in crowded areas.

Errors: 'Because' beginning a sentence is acceptable but the clause was a fragment; subject-verb agreement: 'bike is' should be 'bikes are' to match plural generalization (subject-verb agreement error also but categorized here as adjective/adverb misuse for clarity); duplicated 'cheap cheap' is a repetition error; missing article or plural and 'in crowded area' should be 'in crowded areas' or 'in a crowded area'. Suggestion: make a full clause with plural subject 'bikes are', remove duplicate word, and use plural 'areas' for general statements or 'a crowded area' for a specific case.
