Bike— Part 1 Report

Suggestion: 句子時態與語法不準確，發音和用詞也有模糊（例如“back”應為“bike”或“tricycle”）。回答太混亂且冗長，信息可以更清晰、簡潔。建議：1) 使用正確時態（過去式）和名詞（tricycle, bike）。2) 開頭用一個明確的主題句，然後用一兩句具體細節說明原因或經歷，總句數不超過5句。3) 注意發音和連貫性，可以練習常見詞彙（learned, helped）。

Example: Yes, I had a tricycle when I was a child. It had three wheels and was much more stable than a regular bike, so it helped me learn to balance. I used it in the park near my home almost every day, which made me confident to ride a two-wheeler later.

Suggestion: 回答包含重複和填充詞，語序和時態不夠自然。內容可以更具體：比較過去與現在的情況，給出原因或例子。建議：1) 減少“umm/uh”，使用連接詞（however, nowadays）來組織對比。2) 使用正確名詞（shared bikes, public bike-sharing）和動詞時態。3) 提供一個具體原因或例子支持觀點。

Example: Yes, bikes used to be very popular for daily travel, especially before public transport improved. Nowadays, many people prefer bike-sharing services because they are cheap and convenient for short trips. For example, in my city you can rent a shared bike via an app and leave it near the subway station.

× Yes, when I'm a child, I have a back, but it has four, four wheels different from the modern bike and it help me, it helped me learn.

✓ Yes, when I was a child, I had a bike, but it had four wheels, different from the modern bike, and it helped me learn.

句子中叙述的是过去的经历，应使用过去时。原句使用了现在时（I'm, I have）和混合时态（it help）与情境不符。建议：将所有描述过去的动词改为过去式（am → was；have → had；help → helped），并简化重复词（去掉重复的“four”）。此外注意词序和标点使句子更清晰。

× Umm, yes, umm, in, in the pre previous time, uh, bike is popular, uh, in people, but now it is more uh, shared bike, it's popular.

✓ Yes. In the past, bikes were popular with people, but now shared bikes are more popular.

句子意在比较过去与现在的情况，因此过去部分应使用过去时（were），现在部分使用现在时。原句用“is popular”来表示过去习惯不正确；“in people”搭配错误，应为“with people”或“among people”；“shared bike”作可数名词应使用复数或加定冠词。建议：过去用过去式（were），现在用现在式（are）；使用短语“in the past”替代不规范的“pre previous time”；将“shared bike”改为“shared bikes”以符合语境。
