Bike— Part 1 채점 보고서

제안: 句子時態、語法和句子結構需要改進。回答要直接點明主題句，然後用1–2句具體細節支持。避免重複和含糊表達，並把時態統一為過去式。可以把非正式語氣（like "yeah"）減少，以顯得更自然和流暢。具體建議：1) 用一個清晰的主題句說明是否有自行車；2) 用一兩個短句給出具體細節（誰買的、什麼樣的自行車、你為何喜歡或怎麼用）；3) 注意單詞形式（brought/bought二選一）和定冠詞/不定冠詞的使用。

예시: Yes, I had a bicycle when I was a child. My father bought it for me — it was a small red bike with training wheels. I loved riding it around the neighborhood because it made me feel independent, and my parents encouraged me to practice every weekend.

제안: 內容要更具體並使用連接詞使語意連貫。當提供支持細節時，說明在哪些情況下流行（例如通勤、短途出行、旅遊），以及分享單車如何運作（用App租借、付費方式等）。避免碎片句和不完整句（例如最後一句未完成）。注意名詞複數和冠詞（sharing bicycles, it needs to...）。

예시: Yes, bikes are very popular in my country, especially in cities. Many people use them for short trips and commuting because they are cheap and convenient. In my city there are several bike-sharing services — you just open an app, unlock a bike with a QR code, and pay a small fee by the minute.

× When I am a child, that is my father brought bought for me.

✓ When I was a child, my father bought it for me.

问题类型：现在时使用错误（应使用过去时）。句子描述过去的事件，主句和时间状语“when I was a child”都要求用过去时。原句中使用了“am”和混乱的动词形式“brought bought”。建议：把现在时“am”改为过去时“was”，保留一个正确的过去式动词“bought”，并删除多余的词。

× Yeah, I remember it was a ride bike.

✓ Yeah, I remember it was a bike I used to ride.

问题类型：句子结构错误。原句中“a ride bike”搭配不正确，词序也混乱。建议把意思改为“我记得那是我曾骑的自行车”，使用短语“bike I used to ride”或简单地说“my bike”。

× Yeah, I like it and my parents wanted me to do more.

✓ Yeah, I liked it, and my parents wanted me to ride more.

问题类型：连词和时态不一致。主句应与描述的过去情景一致，故将“I like”改为过去式“I liked”。另外“do more”不够具体，应改为“ride more（更多地骑）”。建议保持时态一致并使用更具体的动词。

× Yes, I think it's very popular and in our city we have sharing bicycle, you know that is everyone can use app and clock the bicycle, but it need to.

✓ Yes, I think they're very popular. In our city we have shared bicycles — everyone can use an app to unlock a bicycle, but they need to pay.

问题类型：现在时和名词/动词形式错误。原句中“it's very popular”与复数“bicycles”不一致，且“sharing bicycle”应为“shared bicycles”或“bike-sharing”。短语“use app and clock the bicycle”错误：应为“use an app to unlock the bicycle”。最后“but it need to”主谓不一致且不完整，应为“but they need to pay”或“but they need to follow rules”。建议：保证主谓一致（复数用they/are），用正确的名词短语“shared bicycles”并用不定式结构“use an app to unlock”。
