自行车— Part 1 評分報告

建議: 句子时态和语法需要纠正，回答要更直接并包含少量具体细节。尽量用现在/过去时一致地描述经历，减少重复并使用连接词使表达更流畅。例如说明什么时候有这辆车、为什么不能骑两轮车以及后来发生了什么。

範例: Yes, I had a bike when I was a child. It was a four-wheeled balance bike that I used until I was about four because I couldn't ride a two-wheeled bike yet. Later, my sister gave me her two-wheeled bike and she helped me practice, so I learned to ride within a few weeks.

建議: 表达要更自然并提供更具体的观察或原因，注意主谓一致和时态。可以用连接词（for example, because）来拓展观点，给出比较或例子支持你的看法。

範例: I don't think bikes are very popular in my country. For example, when I walk along the main roads I rarely see people cycling, probably because public transport is convenient and many people prefer cars for longer distances.

× Yes, I have a bike with four wheels.

✓ Yes, I had a bike with four wheels.

学生在回答过去是否拥有自行车的问题（Did you have...?）时使用了现在时“have”，时态不匹配。应使用过去时“had”。建议在回答关于过去经历的问题时统一使用过去时态，例如用“had”或“I used to have”。（过去时）

× When I'm four years old, I can't to ride.

✓ When I was four years old, I couldn't ride.

句子谈论过去年龄时不应使用现在时缩写“I'm”，应使用过去式“I was”。此外，助动词后不加不定式“to”，应为“couldn't ride”或“could not ride”。错误包括时态使用不当与多余不定式。建议：表示过去能力时用“could/couldn't + 动词原形”，同时将时间表达改为过去式。（时态与情态动词用法）

× I can't ride back with two wheels.

✓ I couldn't ride back on two wheels.

原句时态与问题不一致，应为过去时“couldn't”。介词搭配也不正确，常用“ride on two wheels”来表达用两个轮子骑行，而且“ride back”在此语境不自然；若想表达“回到两轮状态”可说“I couldn't ride on two wheels.” 建议学习常见动词与介词搭配（ride on）。（动词与介词搭配及时态）

× So my sister gave me her bike.

✓ So my sister gave me her bike.

该句语法上无错，时态为过去时，与上下文一致。保留原句即可。尽管句子正确，但可进一步明确因果关系，例如用“Because I couldn't ride, my sister gave me her bike.” 以增强逻辑。

× No, I think bike isn't very popular in my country.

✓ No, I don't think bikes are very popular in my country.

一般事实判断用一般现在时，但原句存在主谓与数的一致问题以及否定表达不自然。应使用“I don't think”来表达否定观点；名词“bike”应为复数“bikes”表示一般性事物；系动词“isn't”不适合跟复数。建议使用“I don't think + 主句”结构来表达个人观点并注意名词单复数一致。（时态与主谓一致）

× I when I walked in the road I didn't see many people ride bike.

✓ When I was walking on the road, I didn't see many people riding bikes.

原句存在多处结构与搭配错误：1) “I when I walked” 多余主语“I”，应直接以从属连词引导从句；2) 动词时态和进行体更自然用“was walking”或简单过去“walked”；3) 介词搭配应为“on the road”；4) “see many people ride bike”应改为“see many people riding bikes”或“see many people riding bikes”以表达目击进行的动作并用复数名词。建议练习时间状语从句结构、进行时用法、介词搭配和动名词形式。（句子结构与动名词）
