Bike— Part 1 Báo cáo

Gợi ý: 回答直接且能理解，但句子結構與時態略不準確，缺乏細節與支持性內容。建議： - 修正句子結構，使語法更自然（例如使用完整句："Yes, I did." 或 "Yes, I had one when I was a child."）。 - 加入一到兩個支持細節（例如你有什麼樣的自行車、幾歲開始、和誰一起騎），以豐富回答但仍保持簡潔（總句數2–3句）。 - 注意時態一致與主詞明確，使用常見詞彙展示語言能力，如 "used to", "when I was about X years old", "a small red bike"。

Ví dụ: Yes, I had a bike when I was a child. I got a small red bicycle when I was seven and I used to ride it to the park with my friend every weekend.

Gợi ý: 回應表達了肯定且有支持理由，整體流暢但最初回覆格式混亂（出現評論語句），且例證句子應改為更自然的現在式或現在完成式並加入具體場景。建議： - 刪除非考試對話的評論語句（例如 “Good job!”）。 - 用一到兩句話給出明確立場並提供具體例子（時間、地點或數量詞），例如說明在市中心、上下班時間、或學校附近看到很多通勤自行車。 - 使用連接詞如 "because", "for example", "so" 使語意連貫。

Ví dụ: Yes, I think bikes are very popular. I often see many people commuting by bike in the city center during rush hour, and there are dedicated bike lanes near schools and offices.

× Yes, I did when I was small.

✓ Yes, I did when I was young.

原句中使用 small 形容年齡在英文中不自然。small 通常形容體型或尺寸，描述年齡應使用 young。建議用 young 來表達「年幼時」。

× I think it is because I always saw them when I was walking on the street.

✓ I think so because I often see many bikes on the streets.

原句中主句用現在時 (I think)，但從句用了過去式 (I always saw)，時態不一致且表達習慣時應使用現在簡單或現在完成。此處使用 often see（現在簡單）可表達習慣性觀察；也可以用 have often seen 表示到現在為止的持續觀察。建議保持主句與從句時態一致以清楚傳達習慣性事實。

× I think it is because I always saw them when I was walking on the street.

✓ I think so because I often see many bikes on the streets.

原句中的代詞 them 指代不明且用法不如直接說 many bikes 清晰。建議明確名詞（bikes）來避免代詞指代不清的問題。

× I always saw them when I was walking on the street.

✓ I often see many bikes on the streets.

原句的介詞短語 on the street 在英語中可接受，但更自然的表達為 on the streets（泛指多條街道）或 in the streets（在街道上）。此外，將 on the street 與現在時結合（see on the streets）更符合描述一般情況。
