Bike— Part 1 採点レポート

提案: 回答直接表达了“没有”，也给出了家庭经济原因，但存在明显的语法、搭配和表达不自然问题。首先，“were still living under the normal income”不自然，应改为“were on a low income”或“didn't earn much money”；其次，过去时应统一使用“couldn't”；“scarcely to buy the meal”语法错误且意思不清，可以改为“could barely afford basic necessities”。此外，语气词“uh”较多，影响流利度。建议使用“直接回答 + 具体原因”的两句结构，并避免重复表达“买不起”。

例: No, I didn't. When I was young, my parents were on a fairly low income, so they couldn't afford to buy me a bike. They could barely cover our basic living expenses at the time.

提案: 回答观点明确，也提供了两个理由：环保和锻炼身体。不过，“as you can see you can witness”重复，应只保留一个表达；“greenhouse effects”应改为更常见的“greenhouse gas emissions”或“air pollution”；“build the body”不自然，可以说“stay fit”或“get more exercise”。句子过长，缺少清晰的连接和标点，建议使用“观点 + 现象 + 两个具体原因”的结构，并用“because”或“also”连接细节。还可以补充共享单车或短途通勤等具体例子，使内容更有效。

例: Yes, bikes are quite popular in my country, especially in big cities. You can see many people riding them to work or using shared bikes for short journeys. This is because cycling is environmentally friendly and also helps people stay fit.

× My parents were still living under the normal income.

✓ My parents were still living on a normal income.

表示“靠某种收入生活”时，英语使用介词“on”，而不是“under”。例如：They live on a low income. 此外，“income”是可数概念的单数表达，前面需要使用冠词“a”。

× So they cannot afford a new bike.

✓ So they couldn't afford a new bike.

整段内容是在谈童年时期的情况，因此应该使用过去时。“cannot”是现在时，“couldn't”是过去时。描述过去没有能力做某事时，使用“couldn't afford to do something”。

× They just scarcely to buy the meal for us.

✓ They could scarcely afford to buy meals for us.

“scarcely”后面不能直接接“to buy”。这里需要一个完整的谓语结构“could scarcely afford to buy”，意思是“几乎没有能力买”。建议掌握“afford to do something”的结构。

× They could scarcely afford to buy the meal for us.

✓ They could scarcely afford to buy meals for us.

这里表示经常性地为家人买饭，而不是一顿特定的饭，所以使用复数“meals”更合适。如果指特定的一顿饭，也可以说“the meal”。

× You can witness with a lot of people riding their bikes on the street.

✓ You can see a lot of people riding their bikes on the streets.

“witness”通常可以直接接宾语，不能使用“witness with somebody”的结构。这里用“see a lot of people”最自然。描述许多街道时，“streets”使用复数更合适。

× It can help us to reduce the greenhouse effects.

✓ It can help us reduce the greenhouse effect.

“greenhouse effect”通常作为一个整体概念使用，因此一般用单数形式“the greenhouse effect”，而不是“the greenhouse effects”。“help somebody do something”中的“to”可以省略。

× It can help them to build the body.

✓ It can help people build their bodies.

“them”在前文没有明确的指代对象，使用“people”可以使意思更清楚。“the body”不能表示每个人的身体；应该使用复数代词“their”搭配复数名词“bodies”。
