自行车— Part 1 評分報告

建議: 回答要更自然、语法更准确，并且句子数控制在5句以内。注意时态和主谓一致（例如: "I had" 而不是 "I had back"；"too expensive to buy" 而不是 "to bought"）。可以用一到两句说明背景，再用一两句具体细节补充，用连接词如 "so" 或 "therefore" 使逻辑更清晰。

範例: Yes, I did. I built my own bike when I was eight because my family couldn’t afford a new one, so they gave me some old parts and tools. After assembling the parts and fixing a few problems, I finally had a whole working bike, which I was very proud of.

建議: 回答总体清晰但可更具体并使用连接词拓展细节。可给出比较、原因或举例（例如交通方便、便宜、环保），并用词更自然（例如 "go to university" 或 "ride bikes to campus"，用 "exercise" 作不可数名词时注意搭配）。

範例: Yes, bikes are very popular, especially among university students. Many students ride bikes to campus because it’s cheap and convenient, and some people also cycle in parks for exercise and relaxation.

× Yes I had back when I was a child.

✓ Yes, I had one back when I was a child.

原句缺少宾语“one（一辆）”。句子时态为过去时正确，但需要完整的名词短语。建议在“had”后加上“one”或“a bike”。此外在“Yes”和“I”之间应加逗号或停顿以符合书面表达习惯。

× I built it myself when I was 8 because my family thought it was too expensive to bought a brand new.

✓ I built it myself when I was eight because my family thought it was too expensive to buy a brand-new one.

错误类型为过去时/动词形式错误：短语“to bought”使用了过去式，正确形式是不定式“to buy”。另外“brand new”作为名词需加“one”或连字符作形容词短语“brand-new”。年龄通常用单词形式“eight”。建议把“bought”改为“buy”，并补充“one”或使用连字符。

× So they just give me some tools and I constructed them by hand.

✓ So they just gave me some tools and I constructed it by hand.

存在时态与代词不一致问题：前半句应使用过去时“gave”与上下文保持一致；“constructed them”中的代词“them”指代不明确且数量不对，修正为“constructed it”指代“bike”。建议统一使用过去时并确保代词与先行词一致。

× Finally it get a whole bike.

✓ Finally it became a whole bike.

语法错误：时态和动词形式不正确。“get”应使用过去式或其他合适动词，此处用“became”更符合表达“最终变成一辆完整的自行车”的意思，也可用“turned into”或“was a complete bike”。另外“a whole bike”可改为“a complete bike”。

× Yes, especially in universities and colleges, students usually go to school by bike or go to park and do more exercises.

✓ Yes, especially at universities and colleges, students usually go to school by bike or go to the park and do more exercise.

包含多个小错误：介词使用不当（应该用“at universities”而不是“in universities”）、缺少冠词（“go to park”需为“go to the park”）、名词数/不可数用法（“exercises”改为不可数“exercise”更常见于泛指锻炼）。保持一般现在时“usually go”正确，但需修正介词和冠词以符合英语习惯。
