Bike— Part 1 채점 보고서

제안: 句子有时态、词汇和句法错误，表达不够自然。建议： 1) 时态要统一：描述过去应使用过去式（例如 had, was）。 2) 词汇选择要准确：不要说 “back bike”，应说 “bicycle” 或 “bike”。 3) 句子结构要更清晰：先用主题句直接回答问题，然后用一到两句补充细节，使用连接词如 “but” 或 “however”。 4) 提供更具体的信息以丰富内容（谁借的、借了多久、是否喜欢等）。 练习要点：多用过去式，注意主谓一致，词序正确。

예시: Yes, I had a bicycle when I was a child. However, it wasn’t my own bike — I usually borrowed it from my older sister for a few hours each afternoon. I loved riding it to the park because it felt freeing and fun.

제안: 表达有时态和流利性问题，且较笼统。建议： 1) 时态一致：用现在时描述当前流行程度（are popular / aren’t popular），用过去时谈过去。 2) 减少犹豫语（uh），提高流利性。 3) 提供具体原因或对比来支持观点，例如交通、城市化、共享单车等。 4) 使用连接词（for example, because, although）让论述连贯。

예시: Bicycles used to be very popular when I was a child, but they are less common now. This is mainly because more people use cars and public transport, and cities have become more crowded. However, bike-sharing programs have made cycling more visible in some areas.

× Yes, I have back bike when I am a child, but this bike is borrowing from another sister.

✓ Yes, I had a bike when I was a child, but this bike was borrowed from my sister.

问题类型：5（过去时问题）和27（主谓一致/动词形式错误）。 问题说明：句子中同时使用了现在时“have/ am”来描述过去的情况，应使用过去时。此外“have back bike”结构不正确，应该说“had a bike”。“this bike is borrowing from another sister”时态与被动/主动混淆，应使用被动过去式“was borrowed from my sister”。 改进建议：在谈论过去的经历时统一使用过去时（例如 used to / had / was），并用正确的被动结构“be + past participle”。将“another sister”改为更自然的“my sister”或“another sister”取决于实际关系；若指自己的姐姐则用“my sister”。 举例改写练习：I had a bike when I was a child. The bike was borrowed from my sister.

× Well, I think the bike is popular when I was a childhood, uh, but now it's not popular.

✓ Well, I think bikes were popular when I was a child, but now they are not.

问题类型：6（现在时问题）和5（过去时问题）以及11（介词/短语用法）和13（词汇搭配）。 问题说明：句子混用了现在时“is popular”和过去时“was”。表达过去习惯应使用过去时“were popular”。短语“when I was a childhood”不正确，正确说法是“when I was a child”。主语单复数不一致：前半句谈一般情况用复数“bikes”，后半句对应用“they”。 改进建议：保持时态一致：描述过去习惯用过去时；注意名词搭配“a child”而不是“a childhood”；主语复数/单数要一致。可多练习将时间状语（when I was a child / when I was young）放在句中并调整时态。 举例改写练习：Bikes were popular when I was a child, but now they are not very popular.
