Bike— Part 1 Report

Suggestion: 语法和时态错误：回答儿童时期的问题应使用过去时；回答过于简短且缺乏细节。建议用过去时直接给出主题句，然后补充一到两句具体细节（如原因、感受或替代交通方式），并使用连接词使回答自然流畅。

Example: No, I didn't have a bike when I was a child. My family couldn't afford one, so I usually walked to school or took the bus. As a result, I didn't learn to ride until I was a teenager.

Suggestion: 回答较为准确且时态正确，但过于简短且缺乏支持性细节。建议在肯定句后用一到两句具体说明原因或例子（例如使用场景、城市 vs 乡村差异、环保或健身等），并使用连接词提高连贯性。

Example: Yes, they are very popular in my country because many people use bikes for short trips and commuting. For example, in cities there are dedicated bike lanes and shared-bike programs, which makes cycling convenient and affordable.

× No, I don't have.

✓ No, I didn't.

学生回答的是过去是否拥有自行车（when you were a child?），所以应使用过去时。原句使用现在时的否定（I don't have）与提问的时态不一致。建议：遇到关于过去的提问（when..., did you...?）应使用过去式，如 I didn't / I didn't have one。

× Yes, they are very popular in my country.

✓ Yes, they are very popular in my country.

该句本身时态正确，回答的是一般事实或现在情况，使用一般现在时（they are）恰当，因此无需修改。
