自行车— Part 1 評分報告

建議: 回答要更自然并且直接回应問題，減少填充語（如 "umm", "uh"），使用一個清晰的主題句，然後用1-2句具體細節支持。可以更正時態（過去時），並縮短句子以保持在5句以內。還可加入連接詞如“because”或“so”使敘述更流暢。

範例: Yes, I had a bike when I was a child. I learned to ride it in primary school with my uncle, who taught me in a nearby park. It took me about three days to feel confident because he patiently guided me until I could balance and pedal on my own.

建議: 回答要語法正確並避免重複。先給出直接回答，再用一兩句具體原因或例子支持，如提及價格、共享單車和城市可見度。使用連接詞如“because”或“nowadays”來組織句子。注意時態一致與拼寫（shared）。

範例: Yes, bikes are very popular in my country. In the past they were more affordable than cars, so many ordinary families owned one. Nowadays, shared bike schemes are widespread and you can see dozens of bikes parked on almost every street corner.

× Yes, I do have a bike.

✓ Yes, I had a bike.

原句使用現在時態（do have），但回答的上下文是談過去（'when you were a child'）。應使用過去時表達兒時擁有的事實，所以把 do have 改為過去式 had。建議：在提到過去發生或存在的情況時，使用過去時（例如：had, was/were）。

× I learned how to ride a bike, umm, with my uncle and uh, I remember he taught me how to ride in a beautiful park and I used three days to learn how to ride it.

✓ I learned how to ride a bike with my uncle. I remember he taught me in a beautiful park and it took me three days to learn.

句中有幾點過去時表達和結構問題：1) 句子過長應拆分為兩個句子以提高清晰度。2) 'I used three days to learn' 的自然英語表達是 'it took me three days to learn'。原句的動詞時態（learned, taught）使用正確，但表達不自然且句子結構混亂。建議：用 'it took me three days' 表示所花時間，並把句子分開以提高流暢性。

× Back then bikes are more affordable were more affordable than cars for ordinary people and nowadays we have sheared bikes which we which can be seen all over the city

✓ Back then bikes were more affordable than cars for ordinary people, and nowadays we have shared bikes which can be seen all over the city.

句子包含多個問題：1) 時態錯誤：'Back then' 指過去，應使用過去式 'were' 而非現在式 'are'（已包含兩種錯誤寫法，保留 'were' 並刪除 'are'）。2) 單詞拼寫錯誤：'sheared' 應為 'shared'（共享的）。3) 重複詞 'which we which' 應刪除多餘部分。整句需以適當的連接詞連接兩個時代對比（過去與現在）。建議：注意時間標誌詞決定時態，檢查拼寫並刪除冗餘詞。
