自行车— Part 1 評分報告

建議: 语法和时态需要改进；回答应更直接并提供具体细节以丰富内容。建议使用正确的过去时（had），并加一两句支持细节，如自行车的颜色、用途或记忆，使用衔接词使句子连贯。回答长度控制在3–4句内。

範例: Yes, I had a bike when I was a child. It was bright red and had a small bell on the handlebar, so I felt proud riding it around the neighborhood. I often rode it to my friends' houses and to the park on weekends.

建議: 内容表达清晰但结构可更自然。建议把主题句和原因分开，用连接词（for example, because, as a result）并加入具体细节或比较，例如不同年龄段或城市与乡村的差异，以显得更具体和有说服力。注意时态和单复数（people ride）。

範例: Yes, I think bicycles are very popular in my country. For example, many people commute by bike in big cities because it is cheaper and faster than driving in traffic. In rural areas, bikes are also common for short trips to the market or school.

× Yes, I have a very pretty bike when I was a child.

✓ Yes, I had a very pretty bike when I was a child.

句子中问题是时态使用不当。询问是过去（"when you were a child"），回答也应使用过去时。原句使用现在时态动词“have”，应改为过去式“had”。建议：在涉及过去时间状语（如 when I was a child, last year, in 2010 等）时，把谓语动词改为过去时。

× Yes, I think bikes are popular in my country because I can see many people ride bikes in the street.

✓ Yes, I think bikes are popular in my country because I can see many people riding bikes in the street.

句子中存在动词形式错误：在“see many people ...”结构中，感官动词 see 后跟宾语加现在分词（表示正在发生的动作）或不带 to 的动词不定式（但含义不同）。这里应使用现在分词“riding”来表示‘看到许多人在骑’。建议：在感官动词（see, hear, watch 等）后描述正在进行的动作时使用动词的 -ing 形式。
