自行车— Part 1 評分報告

建議: 用词和语法需更准确并补充具体细节。回答要直接点出有无自行车，然后用1-2句举例说明（何时、如何使用或为什么喜欢）。避免不自然的短语如“back riding”。也要注意时态和搭配，如“ride a bike”为正确表达。

範例: Yes, I did. I had a small red bike that I learned to ride when I was six, and I often rode it to visit friends in my neighborhood after school.

建議: 回答总体清晰但可更具体，使用连接词丰富逻辑，并给出原因或对比来支持观点。避免模糊词如“some”，用更准确的数量或情景描述。可以说明在哪些城市更常见及原因（例如交通或环保）。

範例: Yes, I do. In many cities bicycles are very common because they are cheap and convenient, so I often see teenagers cycling to school and adults commuting to work, especially during rush hour.

× Yes I did, back riding is one of my hobbies when I was a child.

✓ Yes, I did. Riding a bike was one of my hobbies when I was a child.

问题类型：动词 + -ing 形式（也涉及句子结构）。原句“back riding”是不正确的搭配，应为“riding a bike”。另外原句逗号连接两个独立句子应改为句号；由于谈论过去习惯，主句时态应为过去式“was”。建议：使用正确搭配“ride a bike / riding a bike”，并将时态与时间状语（when I was a child）保持一致。

× Yes, I do. I often see some teenagers or adults riding a bike when they go to school or go to work.

✓ Yes, I do. I often see teenagers and adults riding bikes when they go to school or to work.

问题类型：现在分词使用及名词单复数/搭配问题。原句中“see some teenagers or adults”搭配不太自然，使用“teenagers and adults”更流畅；“riding a bike”在一般陈述中习惯用复数“riding bikes”来表示泛指；另外“go to school or go to work”可简化为“go to school or to work”。建议：用更自然的并列结构，“riding bikes”表示习惯性的动作。
