Bike— Part 1 Report

Suggestion: 句子有语法和表达问题，信息也不够清晰。应直接回答并用一到两句补充细节，注意时态和固定搭配。避免双重否定或不自然的短语，例如 “too poor to avoid an expensive bike” 应改为 “couldn’t afford an expensive one”。可加入具体细节如什么时候得到、谁给的或在哪儿骑，以丰富内容。

Example: Yes, I had a second-hand bike when I was about seven. My parents bought it for me because they couldn’t afford a new one, and I used to ride it around the neighborhood every afternoon.

Suggestion: 回答简洁但略显单薄。应使用更自然的表达并补充一两条具体原因或例子，使用连接词使句子更连贯。例如说明是因环保、交通拥堵或健身趋势导致的普及，并给出地点或群体的例子。注意主谓一致，改用 “riding bikes” → “cycling” 或 “bikes are” 更自然。

Example: Yes, I think cycling is becoming increasingly popular in my country. For example, more people cycle to work to avoid traffic and for exercise, and many cities have built dedicated bike lanes recently.

× I remember I had a second hand bike when I was a child because my family were too poor to avoid an expensive bike.

✓ I remember I had a second‑hand bike when I was a child because my family were too poor to afford an expensive bike.

问题类型：句子结构/词汇搭配错误（归类为“Sentence structure errors”）。 解释：句中 “second hand” 应加连字符写成 “second‑hand” 作复合形容词修饰名词。更重要的是原句用了动词 “avoid” （避免），但语境应表达“买不起”，正确动词是 “afford” （支付得起）。另外，主句时态与从句保持一致，使用过去时“had”和“were”是可以的。改进建议：注意固定搭配（afford 表示“买得起/付得起”），复合形容词在放在名词前时通常用连字符。常练习类似表达，如 “couldn’t afford an expensive bike”。

× Yes, I think riding bikes are becoming more and more popular in my country.

✓ Yes, I think riding bikes is becoming more and more popular in my country.

问题类型：现在时/主谓一致（归类为“Present tense issue”）。 解释：主语是动名词短语 “riding bikes”，作为整体视为单数，谓语应使用单数形式 “is becoming” 而不是 “are becoming”。改进建议：当句子主语是动名词或动名词短语（doing something）时，视作单一活动或概念，用单数动词；平时可练习将动名词短语替换为代词（it）来判断动词形式：“It is becoming more popular.”
