Bike— Part 1 채점 보고서

제안: 回答需要更自然、语法正确并且信息连贯。注意时态和人称的使用（例如不应把年龄用“years ago”与“when I was six”混淆），避免重复填充词（uh, umm）。扩展细节时用一到两句支持，并使用连接词使句子更顺畅。例如说明何时、在哪里骑车、对那辆自行车的感受以及后来发生了什么。

예시: Yes, I did. When I was six my father bought me a bright red bicycle, and I used to ride it on the country roads near our house. I loved going up and down the hills with my friends, although after a few years it became too small for me so he sold it and I got a larger one.

제안: 回答要更简洁、词汇更准确并补充具体细节。避免自我纠正和口头填充词，使用连接词（for example, moreover）来组织信息。可以说明共享单车的便利性、使用场景和影响（如交通、环境）。结尾应有完整句子，而非断句。

예시: Yes, I think bicycles are very popular in China. For example, shared bikes can be found on almost every street, and people simply scan a QR code to unlock them, which makes short trips very convenient. Moreover, bikes help reduce traffic congestion and pollution in many cities.

× Absolutely. Uh, when I was about six years ago, my father bought me a red bike and it's big.

✓ Absolutely. When I was about six years old, my father bought me a big red bike.

句子中存在時態與時間短語搭配以及詞序問題。“when I was about six years ago”是錯誤重複（既使用 when 引導過去時間，又加上 ago），正確表達應為“when I was about six years old”或“about six years ago”。另外，形容詞的常規順序應為數量/大小/顏色，因此“a big red bike”比“a red bike and it's big”更自然。建議：使用正確的時間表達（when + 年齡 OR + ago），並將形容詞按常規順序排列。

× It can and I wrote it in the mountains, uh, but unfortunately, uh, it was too small for me now.

✓ I used to ride it in the mountains, but unfortunately, it became too small for me.

原句“It can and I wrote it in the mountains”語法錯亂，應表達過去習慣性動作用“used to”或過去式“rode/used to ride”。此外時間對比用詞不當，“was too small for me now”混合過去與現在，應使用一致的過去觀點，如“became too small for me”。建議：表達過去習慣用“used to + 動詞原形”或簡單過去；描述變化用過去式如“became”。

× Yes, I did think so. I do think so umm, you know in China we can see a lot of shared bicycle, bicycles all around the street, all uh, on the street everywhere.

✓ Yes, I do think so. In China we can see a lot of shared bicycles all over the streets.

句子中時態和助動詞使用不一致。“Yes, I did think so. I do think so”混合過去和現在，回答現在看法應使用現在時“I do think so”。名詞單複數錯誤：“shared bicycle”應用複數“shared bicycles”。介詞搭配“all around the street/on the street everywhere”不自然，常用表達為“all over the streets”或“everywhere on the streets”。建議：保持時態一致（此處用現在時），注意名詞複數形式，使用自然的介詞短語。

× People can just scan the QR code and uh, they can only.

✓ People can just scan the QR code and unlock the bike.

原句“they can only”句子不完整，缺少賓語或動作結果，導致句子結構不完整。根據語境應補充動作結果，例如“unlock the bike”或“use it”。建議：說完整句子，表達掃碼後的具體結果，如“scan the QR code and unlock the bike”或“scan the QR code and use it”。
