Bike— Part 1 채점 보고서

제안: 回答要用正确的时态并更简洁连贯。现在学生用“do have”而问的是过去，应该用过去时；存在重复词（“to to to”）和冗余。可以先一句直接回答（主题句），随后用一两句具体细节（谁教你、什么时候、和谁一起骑）并使用连接词使表达更顺畅。注意动词形式和单复数一致。

예시: Yes, I did. My grandfather taught me to ride when I was about seven, and later I often cycled around the neighborhood with my friends on weekends.

제안: 回答总体明确但口语填充词太多且句子结构有些混乱。应减少“umm/like”填充词，使用连词（for example, because, so）使逻辑更清晰。举一两个具体例子（公共共享单车的普及、骑行的便利性或停车问题）并用简单句或复合句表达原因。

예시: Yes, they are. For example, bike-sharing programs are widespread, so many people rent bikes for short trips. Bikes are convenient in cities because they are cheap, easy to park and often faster than cars during rush hour.

× Yes I do have a bike.

✓ Yes, I had a bike.

原句使用現在時態 (do have)，但問題是詢問過去是否擁有自行車（When you were a child），因此應使用過去時 had。建議：根據時間副詞（when I was a child）把動詞改為過去式。

× When I was a child my grandpa taught me to to to ride a bike and later I always ride a bike with my friends and go biking.

✓ When I was a child my grandpa taught me to ride a bike, and later I always rode a bike with my friends and went biking.

句中有多處時態不一致。主句描述過去經歷（When I was a child），應該整句使用過去時: taught（正確）、但後面用現在時 ride, go 應改為過去式 rode, went。此外有多重重複的'to'，應刪除多餘項。建議：保持時態一致，將描述過去習慣和活動的動詞改為過去式，並刪除多餘字詞。

× Yes, of course umm, there are many, umm, many public bikes that everyone can, can umm, spend some money to share to use them.

✓ Yes, of course, there are many public bikes that everyone can rent for a small fee and use.

原句中有冗長且不自然的表達（share to use them），以及重複詞。'There are' 用法本身可以，但後面動詞搭配不當。建議：用更自然的動詞搭配 (rent for a small fee / share bikes) 並刪除重複詞，使句子更簡潔明確。

× And bikes are very convenient in our city, like umm, like you don't have need to find a place to park your car.

✓ Bikes are very convenient in our city; for example, you don't need to find a place to park your car.

原句語序和助動詞使用不當：'don't have need to' 是錯誤搭配。正確為 'don't need to' 或 'don't have to'. 建議：使用 'don't need to' 或 'don't have to'，並刪除多餘的重複詞 'like'. 句子時態為一般現在，保持不變。
