自行车— Part 1 评分报告

建议: 语法和时态错误需要纠正，句子应直接回应问题并且保持简洁自然。注意主语与动词的一致（were → was），以及否定助动词的使用位置。可以加一句简短的原因或替代回忆来丰富内容，但总句数不超过5句。

示例: No, I didn't have a bike when I was a child. I grew up in a small apartment and my parents thought it wasn't safe for me to ride on busy streets, so I usually played indoors or rode scooters nearby.

建议: 回答不完整且有语法问题。“In 10 years ago”是错误表达，应使用“10 years ago”或“in the past 10 years”等，并在回答中给出具体理由或例子来支持观点。使用连接词（because, for example, recently）使回答更连贯。控制在最多5句内。

示例: Yes, I think bikes are very popular in my country, especially in cities. For example, many people use public bike-sharing schemes for short trips, and cycling lanes have increased a lot in the past ten years because of traffic and environmental concerns.

× No, I didn't have a bike when I were a child.

✓ No, I didn't have a bike when I was a child.

语法类型ID:27 主谓一致错误/人称形式错误（对应题单中的“Subject-verb agreement errors”）。 说明（简体中文）：句中从句“when I were a child”使用了动词过去式的复数/非第一人称形式“were”，但主语是第一人称单数“I”，因此应使用过去式单数形式“was”。改正后与主句“didn't have”（过去时）保持一致，表达“我小时候没有自行车”。 建议：记住be动词在过去式中随主语变化：I/he/she/it → was；you/we/they → were。日常练习中可多造句，例如“I was at home.”、“They were at school.”来巩固。

× Yes, I think bikes are popular. In 10 years ago.

✓ Yes, I think bikes are popular. Ten years ago, they were also popular.

语法类型ID:26 句子结构错误。 说明（简体中文）：短句“In 10 years ago.”结构不完整并且时间短语与“ago”同时使用存在冗余错误。正确表达过去某一时间点应使用“Ten years ago”作为完整句子的时间状语并接谓语，例如“Ten years ago, they were also popular.” 或者如果想表达“在未来十年内”应使用“in ten years”。 建议：区分“in ten years”（表示从现在起十年后）和“ten years ago”（表示十年前）。使用带有“ago”的时间短语时通常放在句首或句尾并需有谓语动词：例如“Ten years ago, I lived in Beijing.” 或 “I lived in Beijing ten years ago.”。
