Bike— Part 1 채점 보고서

제안: 用时态和语法更准确、句子更自然并控制长度。回答应以主题句开头，然后用1-2句具体细节支持。注意过去时态（had, loved），避免重复信息。可以加入简单连词让句子更流畅，例如“and”或“so”。

예시: Yes, I had a bike when I was a child. I loved riding it with my schoolmates after school, and we often explored nearby parks and streets.

제안: 提高语法准确性和表达清晰度，使用恰当时态和搭配（例如“used to be popular”，“younger generation often look at their phones”）。回答要更具体，给出原因或例子并用连接词组织逻辑，如“because”或“however”。避免冗长重复。

예시: They used to be very popular, but nowadays fewer young people ride bikes because they prefer spending time on their phones. As a result, cycling is less common in cities, although some people still use bikes for short trips or exercise.

× Yes, I have a bike when I was young.

✓ Yes, I had a bike when I was young.

句子原本使用現在時態（have）與過去時間狀語（when I was young）不一致。應將動詞改為過去式 had，以符合過去時間。建議在談論過去經歷時，整句使用過去時態。

× I love cycling with my schoolmate when I was young.

✓ I loved cycling with my schoolmate when I was young.

句中時間狀語表明行為發生在過去，但主句使用現在式 love 與過去時間不匹配。把動詞改為過去式 loved。另可注意複數：如果指不只一位同學，應用 schoolmates。

× I love cycling with my schoolmate when I was young.

✓ I loved cycling with my schoolmates when I was young.

原句使用 schoolmate（單數），語境通常指與同學一起騎車，應為複數 schoolmates（多位同學）。若只指一位同學，則需明確上下文。建議根據實際意思選單數或複數。

× I think bike is used to be popular in my country but now the younger generation always look at the phone and don't do sport.

✓ I think bikes used to be popular in my country, but now the younger generation always look at their phones and don't do sports.

1) 名詞複數：表示一般情況應使用 bikes 而非單數 bike。2) used to 固定短語表示過去習慣，不加 be。3) phone 與 younger generation 不匹配，應用複數 their phones；sport 在英式可用不可數，但美式常用 sports。建議用複數形式及固定短語 "used to"。

× So I think it's become not popular in nowadays.

✓ So I think it has become unpopular nowadays.

原句中 it’s become not popular 結構不自然，且 nowadays 已表示現在時，不需加 in。應使用現在完成時 has become 表示從過去到現在的變化，並用形容詞 unpopular 代替 not popular。整句改為 "it has become unpopular nowadays" 更地道。
