Bike— Part 1 Report

Suggestion: 在回答时要注意时态和语法的一致性，句子要更简洁并包含主题句与支持细节。可以把经历按时间顺序清楚表达，并用连接词使句子更连贯。例如纠正动词时态（had / rode / hadn't ridden）和主谓一致，同时避免重复信息。尽量控制在最多五句内。

Example: Yes. I had a bike when I was in primary school. I enjoyed riding it around the neighborhood, but I haven't ridden it for almost eight years. When I started senior high school, bicycles were not allowed on campus, so I stopped using it.

Suggestion: 回答要更准确地表达时间和原因，使用恰当的时态和连接词。避免重复短语（如“share bike, they share bikes”），用更丰富但贴切的词汇描述趋势（e.g. bike-sharing scheme, commuting）。提供一个简短的结论句来总结观点。控制在五句以内。

Example: Yes, bikes have become very popular in my country over the past decade. The introduction of bike-sharing schemes about twelve years ago made cycling much more accessible. Many people now use bicycles to commute to work or school because they are cheap and convenient. Overall, cycling is an important part of urban transport here.

× Yes I have a bike when I was a in my primary school I think, but I haven't ride my bike for almost 8 years because when I get into the Senior High School we not alone we're not allowed to do so.

✓ Yes, I had a bike when I was in primary school, I think, but I haven't ridden my bike for almost eight years because when I got into senior high school we weren't allowed to do so.

包含多个时态和形式问题： 1) 原句“I have a bike when I was in my primary school”在时间上混用现在时和过去时，描述过去的情况应使用过去时“had”。 2) “a in my primary school” 有多余的冠词和词序错误，应为“in primary school”或“in my primary school”。 3) “I haven't ride”是现在完成时与动词不定式原形的错误搭配，正确应为现在完成时+过去分词“haven't ridden”。 4) “when I get into the Senior High School”时态不一致，描述过去应使用过去式“got”。 5) “we not alone we're not allowed to do so”包含双重错误：否定表达不正确且多余片段，“we weren't allowed to do so”即可。 改进建议：注意在同一时间框架内统一时态（过去事件用过去时或现在完成时视是否与现在相关），掌握完成时结构（have/has + 过去分词），并检查多余词和否定结构。

× I think the bike is popular since about 12 years ago because at that time they share bike, they share bikes appeared and a lot of people choose bike to, uh, get to their workplace, work it to school because it's cheap and convenient.

✓ I think bikes have been popular since about twelve years ago because shared bikes appeared at that time and a lot of people chose bikes to get to their workplace or to school because they're cheap and convenient.

句中存在时态和形式错误： 1) “the bike is popular since about 12 years ago”使用现在时与“since + 时间点”搭配时常用现在完成时表示从过去持续到现在，应为“have been popular”。 2) “they share bike, they share bikes appeared”表达混乱，正确为“shared bikes appeared”或“bike-sharing appeared”。 3) “a lot of people choose bike to ...”描述过去起始事件时应使用过去式“chose”，且单数/复数和搭配应为“choose bikes to get to...”。 4) “work it to school”是不正确的短语搭配，改为“get to their workplace or to school”。 5) 句尾“it's cheap and convenient”若主语为复数“bikes”应使用“they're cheap and convenient”或“it is cheap and convenient”指代系统时需一致。 改进建议：使用合适的完成时态表达从过去到现在的持续状态，注意名词单复数一致和固定搭配（get to work/school, bike-sharing），保持主语与动词的一致性。
