Bike— Part 1 Báo cáo

Gợi ý: 回答句子时态与细节需更准确，避免时态混用；开头要直接回应并加入一两句支持细节，使用连接词让表达更自然。比如把时态统一为过去时，并说明你对自行车的记忆或用途。可以把回答扩展为不超过五句。

Ví dụ: Yes, I did. My grandfather bought me a small red bike when I was about seven, and I rode it almost every afternoon after school. It was quite simple but sturdy, and learning to ride it gave me a lot of confidence.

Gợi ý: 回答要更具体并使用连接词自然衔接观点；提供具体例子或对比能增强说服力。避免列数字而不展开，加入简短说明为什么便利和环保，并可举一两个具体场景。保持不超过五句。

Ví dụ: Yes, they are. Firstly, bikes are very convenient for short trips in busy cities because they are easy to park and can avoid traffic jams. Secondly, many people prefer cycling as a low‑cost and eco‑friendly alternative to driving, especially for commuting to work or going to the market.

× Yes, I have a bike.

✓ Yes, I had a bike.

原句使用現在時態“have”，但提問是過去式“Did you have... when you were a child?”應使用過去時態“had”。建議根據提問時態把動詞改為過去式以保持時態一致。

× When I was a child it was bought from my grandpa.

✓ When I was a child it was bought by my grandpa.

原句中使用被動語態時，表示動作的執行者應用介詞by而不是from。‘bought from my grandpa’表示從爺爺那裡買到（通常主語是我買東西），而被動句要表明動作者時應用‘bought by my grandpa’。建議使用‘by’來標示動作執行者。

× Yes, of course, and there are mainly 2 reasons.

✓ Yes, of course, and there are mainly two reasons.

原句不是語法錯誤，但數字書寫建議在正式書面英語中用單詞形式'two'代替阿拉伯數字'2'。此外此句時態與上下文匹配，無需改變。

× The first one is that it is very convenient and the second one is that it can protect the environment.

✓ The first reason is that it is very convenient, and the second is that it can protect the environment.

原句中重复使用'one'顯得冗餘，可改為'reason'或省略one以使語句更自然。同時在連接兩個分句時加逗號更符合書面習慣。建議使用更自然的表達：'The first reason... and the second...'。
