Bike— Part 1 채점 보고서

제안: 回答要更自然并且時態一致。可先用一句主題句直接回答，然後用一到兩句具體細節說明，例如你多大開始騎、和誰一起騎、在哪裡騎、或有什麼有趣回憶。避免語法錯誤（如 play → played）和冗長或模糊表達。

예시: Yes, I did. I got my first bike when I was about six and I often rode it around my neighborhood with my friends. We would race along the park paths and sometimes stop to buy ice cream from a nearby shop.

제안: 回答要更完整並提供具體細節或理由。先用一句主題句表明看法，然後用連接詞（for example, because, especially）補充具體原因或例子，如共享單車的普及、環保與通勤便利等。注意語法與單複數（e.g. has → have if plural subject）以及詞彙精確。

예시: Yes, bicycles have become much more popular recently because many cities now offer public bike-sharing systems. For example, visitors and commuters use these bikes for short trips since they are cheap, convenient and environmentally friendly.

× I had a bike when I was a child and I always play with my neighborhood.

✓ I had a bike when I was a child and I always played with my neighborhood.

句子中描述过去习惯的动作，应使用过去时。原句中主句开头用过去时“had”，但后半句误用现在时“play”，时态不一致。建议将“play”改为过去式“played”，或使用过去常态结构如“always used to play”。另外，“play with my neighborhood”表达不自然，常见说法是“play with my neighbourhood friends”或“play around the neighbourhood”，可根据意思调整。

× It's become more popular recently.

✓ It has become more popular recently.

原句用缩写“It's”通常表示“it is”或“it has”。在此句中要表示最近已经变得更流行，应使用完成时“has become”，完整形式为“It has become”，缩写可写作“It's”但会被误解。为清晰建议写出完整形式或用正确的缩写“It's”仅在等同于“it has”且口语中可接受。

× Every city has the public bikes for everyone, especially for the visitor.

✓ Every city has public bikes for everyone, especially for visitors.

1) “the public bikes”中定冠词“the”不必要，通常说“public bikes”。2) “for everyone”可以接受但“for the visitor”应使用复数“visitors”来表示一般的人群，而不是特指单个游客；同时不需要前置冠词“the”。因此改为“for visitors”。
