Bike— Part 1 채점 보고서

제안: 用更自然、简洁且结构清晰的回答。开头直接回答问题，然后用一两句具体原因支持，避免冗长或语法错误。注意时态和固定搭配（例如："make a fuss"而不是"make drama"，"ride a bike"而不是"keep balance at the bike"）。控制在最多五句。

예시: No, I didn't. My parents thought it wasn't necessary because we lived close to my school, and I also found it difficult to balance on a bike when I was young. So they never bought one for me, and I usually walked or took the bus instead.

제안: 回答要更有条理并用更准确的表达。先直接给出观点，然后用一两句具体例子支持，使用连接词如"for example"或"because"来衔接。注意名词和代词的一致性（例如："public bikes"或"shared bikes"，不用"their"指代国家）。控制在最多五句。

예시: Yes, I think bikes are very popular in China. For example, shared bike services are widespread: you simply scan a QR code to unlock a bike and ride it to your destination. This system is convenient, affordable and helps reduce traffic and pollution.

× Actually, no. When I was a child, my mother always made drama to school and a bike wasn't necessary for me.

✓ Actually, no. When I was a child, my mother always drove me to school, so a bike wasn't necessary for me.

句子中短语 "made drama to school" 不符合英语表达习惯且语义不明。应把意思改为“送我去学校”——用动词 drive 或 take。这里使用过去时态（was, wasn't）与叙述过去的背景一致。建议记住常见的固定搭配：drive/take sb to school（开车/带某人去学校）。

× Moreover, it's hard for me to keep balance at the bike, so I didn't have a bike when I was a child.

✓ Moreover, it was hard for me to keep my balance on a bike, so I didn't have one when I was a child.

错误点有两处：1) 时态不一致，句子在讲过去经历，主句应使用过去时（it was hard），而不是现在时（it's）。2) 介词和名词搭配错误，应说 keep my balance on a bike（而非 at the bike）。另外，可用代词 one 代替前文重复的名词。建议注意时态一致性以及常用搭配 keep (one's) balance on a bike。

× In addition, in China, their public bikes on the road, you can scan the QR on the bike and you can drive it to anywhere you want.

✓ In addition, in China there are public bikes on the road; you can scan the QR code on a bike and ride it to anywhere you want.

原句存在代词和结构问题：1) 使用 'their' 指代不明且不需要；应使用存在句 there are 表示“有公共自行车”。2) 缺少名词 'code'（QR code）。3) 动词搭配错误，通常用 ride a bike（而不是 drive it）。建议用 there are 引入存在情况，使用明确的名词和常见动词搭配。

× It's convenient and beneficial to the environment.

✓ It's convenient and beneficial for the environment.

介词搭配错误：英语中常用 beneficial to 或 beneficial for 表示“对……有益”，但在此上下文中更常用 beneficial for the environment。建议记住常用搭配：beneficial for/to something，并根据语境选择。
