Bike— Part 1 採点レポート

提案: 句子需要时态和语法一致，表达更自然。回答应直接回应问题并补充具体细节（例如年龄、感受或替代交通工具），同时避免冗长或不准确的陈述。可以把三句压缩成一到三句，注意动词时态（过去式）和单复数。

例: No, I didn't. My family couldn't afford a bicycle when I was a child, so I usually walked to school or took public transport.

提案: 内容不相关且有语法错误（例如“Bags”应为“Bikes”，时态和搭配不当）。回答要直接回应问题，给出具体原因或例子，并使用连接词使逻辑清晰（例如 because, for example, recently）。限制在一到三句内，词汇选择要准确。

例: Yes, I think bikes are quite popular in my country because many people use them for short trips and commuting; for example, in cities bicycles and e-bikes are common for getting to work.

× No I didn't. My family was poor at that time. We can't afford a bicycle for child just for fun.

✓ No, I didn't. My family was poor at that time. We couldn't afford a bicycle for children just for fun.

句子中原用了现在时态的情态动词“can't”来描述过去的情况，应使用过去时的情态动词“couldn't”。另外，“child” 用作可数名词时需用复数或加冠词，此处意思是“供孩子骑的自行车”，应改为复数“children”。建议：描述过去的能力或可能性时用过去式情态动词（could/couldn't）；注意可数名词在泛指多类对象时应使用复数。

× Yes I do. Bags is very popular in our country.

✓ Yes, I do. Bikes are very popular in our country.

原句把要表达的名词写成“Bags”而且动词与主语不一致。正确问句是关于“bikes（自行车）”，应使用复数名词“bikes”，相应动词用复数形式“are”。建议：注意主语的拼写和与动词的一致（单复数一致）。

× In the past 30 years, it's a very traditional transformation in my country.

✓ In the past 30 years, there has been a significant transformation in my country.

原句结构和时态不当：用“it's a very traditional transformation”既语义模糊又与“in the past 30 years”时间状语不匹配。描述过去三十年发生的变化应使用现在完成时（there has been...）或过去完成/过去时，根据持续影响选择现在完成时更合适；同时用“significant”或“great”比“traditional”更符合“转变”的含义。建议：表述一段时间内发生的变化常用现在完成时，并选用准确形容词表达意思。
