Bike— Part 1 채점 보고서

제안: 回答要更自然、语法正确并且稍微扩展内容。避免重复（例如两次说“You did have”），并补充一两句具体细节（比如年龄、车的类型或与谁一起骑），用连接词使句子连贯。

예시: Yes, I did. I had a small red bicycle when I was about seven, and I used to ride it around the neighborhood with my friends every afternoon.

제안: 回答总体内容不错，但语言需更自然、用词更准确并避免重复（两次用“even”）。增加连接词和具体细节（例如用户群体、使用场景或优点），并注意“electricity bike”应为“electric bike”。

예시: Yes, bicycles are very popular in my country, especially in the capital. For example, there is a shared bike system called YouBike that offers both regular and electric bikes, which many commuters use to travel short distances because it’s cheap and convenient.

× Yes I did. I did have a bike when I was child.

✓ Yes, I did. I had a bike when I was a child.

句子中使用了兩次助動詞/did/（"Yes I did. I did have..."）會顯得冗餘。回答第一句 "Yes, I did." 已經表示過去有這個事實，接下來描述應使用一般過去時的實義動詞形式，因此應寫成 "I had a bike when I was a child."。另外，缺少冠詞 "a" 在 "a child"。建議：在肯定一般過去的陳述中直接使用過去式動詞（had），並注意在 "child" 前添加不定冠詞。

× Yes, it is popular in my country.

✓ Yes, they are popular in my country.

此句談論的是 "bikes"（複數），但原句主語使用了單數代詞 "it" 和單數動詞 "is"，造成主謂不一致。正確應使用複數代詞/動詞 "they are"。建議：說到複數名詞時，用複數代詞（they）和複數動詞（are）。

× We even have a shared bike station called Ubike, especially in the capital city.

✓ We even have shared bike stations called Ubike, especially in the capital city.

原句使用了單數 "a shared bike station" 但描述的是一種設施的普遍存在（尤其在首都），更自然的是用複數形式 "stations" 或改為指單一設施時加以明確。此處選擇複數以匹配普遍性描述。同時，若品牌為 "Ubike" 並有多個站點，應使用複數。建議：當表達某類設施普遍存在時，使用複數名詞以符合語境。

× They even offer the electricity bike for people to rent.

✓ They even offer electric bikes for people to rent.

"electricity bike" 是錯誤搭配，正確形容詞應為 "electric"，且因為有多輛車可租，應使用複數 "bikes"。因此應改為 "electric bikes"。另外，動詞 "offer" 與不定式 "to rent" 搭配可接受，語意為提供租賃服務。建議：用形容詞 "electric" 修飾名詞 "bike"，並根據可數名詞的數量使用單數或複數。
