自行车— Part 1 评分报告

建议: Be direct, grammatically correct, and give one or two specific supporting details. Start with a clear topic sentence (past tense for past events), then add a reason or short example using a linking word. Avoid vague phrasing like “this is the use of.”

示例: Yes. I had a bicycle when I was a child. It was inexpensive but very useful for getting to school and visiting friends, so I rode it almost every day.

建议: Answer directly and expand with a specific reason or comparison using linking words. Use correct grammar (singular/plural and articles) and provide one concrete example or statistic if possible to support your claim.

示例: Yes, bicycles are very popular in my country because they are affordable and convenient. For example, many people ride bikes to work or market, especially in small towns, which helps them save money on transport.

× Yes, when I was a child, I have a bike and this is the use of. This is a cheap but useful in our country.

✓ Yes, when I was a child, I had a bike and it was useful. It was cheap but practical in our country.

Problems: incorrect tense (present 'have' used for past context) and awkward phrasing. Grammar problem type ID 6 (Present tense issue) applies because the student used present tense where past tense is required. Corrections: change 'have' to 'had' to match 'when I was a child'; replace 'this is the use of' with 'it was useful' to produce a natural past-tense statement; change 'This is a cheap but useful' to 'It was cheap but practical' to use correct adjective and past tense. Suggestion: ensure verbs agree with the time reference in the sentence (use past tense for past events) and choose appropriate adjectives ('practical' instead of repeating 'useful').

× Yes, in my country bike is the most popular and this is cheap but useful.

✓ Yes, in my country bikes are very popular and they are cheap but useful.

Problems: singular/plural mismatch and tense/number agreement. Grammar problem type ID 1 (Singular and plural issue) applies because 'bike' should be plural when speaking generally, and 'is' should match plural subject. Corrections: change 'bike is the most popular' to 'bikes are very popular' to speak generally; 'this is cheap but useful' becomes 'they are cheap but useful' to match plural subject. Suggestion: use plural nouns and plural verbs when referring to things in general, and match pronouns to the noun number ('they' for 'bikes').
