Bike— Part 1 채점 보고서

제안: 句子應更自然、語法要正確，並把信息組織成一個主句加上至多兩個支持句。注意時態（過去式）、單複數一致以及連接詞的使用。可以把細節更具體，例如說明何時開始騎、是否使用輔助輪、對當時感受的描述。

예시: Yes, I did. I had a small red bike when I was about six. It came with training wheels, which made me feel safe at first, and I practiced every day until I could ride without them.

제안: 回答需更準確與連貫，避免重複表達。說明原因時使用連接詞（for example, because, such as）並提供具體細節或比較，例如提到共享單車帶來的便利或交通影響。注意詞語搭配（shared bikes / scan a code / unlock）和語法。

예시: Yes, bikes are very popular in my country, especially in cities. For example, many people use shared bikes because you can just scan a QR code to unlock one, which is cheap and convenient for short trips.

× Yes, of course. I have a bike in my childhood.

✓ Yes, of course. I had a bike in my childhood.

原句使用現在時 (have) 與時間狀語“in my childhood”（過去時間）不一致，應使用過去時。建議使用過去式 had，或改為現在完成時加明確時間範圍（I have had a bike since I was a child）視語境而定。

× It's designed especially for kids because it have two small wheels on its back wheel.

✓ It's designed especially for kids because it has two small wheels on its back wheel.

主語為單數（it），動詞應用第三人稱單數形式 has。不應使用 have。建議記住主語為he/she/it時動詞要加 -s。

× It's designed especially for kids because it have two small wheels on its back wheel.

✓ It's designed especially for kids because it has two small wheels on its back.

原句中“two small wheels on its back wheel”結構重複且不通順，應刪去多餘的“wheel”以表達“在後輪（後方）有兩個小輪子”。重組後語義更清晰。

× It's suitable for beginners like me. Avoid falling down when I first ride the bike.

✓ It's suitable for beginners like me. I avoided falling down when I first rode the bike.

第二句為獨立句但缺少主語和正確的時態。原句“Avoid falling down when I first ride the bike.” 既像祈使句又與前句時態不符。根據描述的過去經驗，應使用過去時並加主語：I avoided ... 或 I didn't fall ...；若想表達“為了避免摔倒”應用不定式或動名詞結構（to avoid / avoiding）。

× You can see a lot of shared bike on the street and people just scan the code and write it.

✓ You can see a lot of shared bikes on the street and people just scan the code and ride them.

“a lot of”後面若接可數名詞應使用複數形式 bikes，而原句使用單數 bike 錯誤。另外“write it”語義不合，應為“ride them”（騎車）。建議注意可數名詞單複數搭配及動詞選擇。

× You can see a lot of shared bike on the street and people just scan the code and write it.

✓ You can see a lot of shared bikes on the street and people just scan the code and ride them.

原句中的動詞串聯應保持平行結構：scan the code and ride them。原句“scan the code and write it”使用了錯誤的動詞 write 並且代詞 it 指代不明。建議保持動詞平行並確保代詞與先行詞數一致。

× So it is very convenient for people and it's very popular.

✓ So it is very convenient for people and very popular.

句子本身時態無誤，但連接後半部分重複使用主語+動詞“it's very popular”在口語可以，但書面上可簡化為“and very popular”。若保留完整句子亦可，無需兩次表達相同意思。
