Bike— Part 1 채점 보고서

제안: 语法和时态错误较多，句子结构不够自然。回答应直接回应问题，使用正确的过去时态，合并信息以避免冗长，最好不超过5句。具体建议： 1) 将动词改为过去式（had, bought）。 2) 用更自然的表达合并两句，例如说明什么时候得到以及对你的意义。 3) 使用连接词如“and”或“which”使句子连贯。 示例句中要包括主题句和1-2个细节句，保持简短且具体。

예시: Yes, I had a bike when I was a child. My mother bought it for me as a birthday present, and I used to ride it to school every day.

제안: 句子混乱且时态不一致，表达不清晰。需要先给出直接观点，然后用简洁的原因或对比支持观点。具体建议： 1) 明确使用过去/现在时（were popular / are more popular now）。 2) 使用连接词（but, however, because）来清晰对比过去与现在的情况。 3) 给出具体原因或例子（如私家车或共享单车的普及）。 回答控制在1-3句内，逻辑清楚。

예시: Bikes used to be very popular when I was young, but they are less common now because more people own cars and there are many shared bicycles and scooters in cities.

× Yes, when I was a child I have a new bike.

✓ Yes, when I was a child I had a new bike.

该句主句发生在过去（“when I was a child”），动词时态应与时间状语一致，使用一般过去时。原句使用现在时“have”与过去时间冲突。建议把“have”改为过去式“had”。

× This bike was my mother buy for me.

✓ This bike was bought for me by my mother. / My mother bought this bike for me.

句子是描述过去发生的动作，应使用过去式或过去分词构成被动语态。原句中“was my mother buy”语序和时态都不正确。可以改为被动语态“was bought ... by my mother”或主动语态“My mother bought ...”。建议根据想表达的侧重点选择其中一种正确结构。

× Before when I was young the bikes were popular in our country, but now the most popular was is.

✓ When I was young, bikes were popular in our country, but now cars are the most popular.

该句包含时态不一致和表达不清的问题。第一部分描述过去，应使用一般过去时“were”，这是正确的；但第二部分应描述现在情况，需用现在时“are”。原句“was is”是混合错误且“the most popular”后缺少具体名词，需补全，如“cars are the most popular”。建议把句子拆成两部分并分别使用与时间相符的时态，同时补充比较对象。
