Bike— Part 1 採点レポート

提案: 回答直接且信息明确，但可改进语法时态一致性、句子连贯性和细节丰富度。建议使用一致的过去时，合并短句并加入1–2个具体细节，如骑行频率、感受或与谁一起骑，以使回答更自然流畅。例如可以在一句话内说明时间和背景，并用连接词衔接。

例: Yes — I had a pink bike when I was a child, and I rode it to school almost every day. I usually went with my friends, which made the trip fun and helped me feel independent.

提案: 观点明确，但表达需更自然、语法准确并提供具体原因或比较细节。注意名词单复数和冠词（a bike/the bike），避免笼统表述。建议先给出总体评价，再用连接词（for example, because）补充两到三个具体原因，如方便、速度、成本或城市环境影响。

例: Yes, bikes are common, but electric bikes are more popular in China because they are faster and don't require much effort. For example, many people use e-bikes to commute short distances since they save time and cope better with traffic and hills.

× It's a pink bike.

✓ It was a pink bike.

学生在描述过去拥有的自行车，整段话的时态是过去时（Did you have... / I had... / when I was a child），句子用现在时“It's”与上下文时态不一致。应使用过去时“was”。建议：回顾过去时态的使用，描述过去的事物要把系动词用过去式（is -> was）。

× I often ride it to go to school.

✓ I often rode it to go to school.

句子主体是在讲过去经常做的动作，需使用过去时。现在时“ride”与上下文不符。建议：描述过去习惯性动作时使用过去式（often + 动词的过去式）。

× Of course bike is cheap, but in my country China, electric bike is more popular than traditional bike.

✓ Of course bikes are cheap, but in my country China, electric bikes are more popular than traditional bikes.

这里说的是一般性复数概念（自行车、电动自行车、传统自行车），应使用复数形式。原句用单数“bike/electric bike/traditional bike”造成数的一致性错误。建议：表达一般类别时通常用复数（bikes, electric bikes, traditional bikes）。

× I think it's more convenient than traditional one.

✓ I think they're more convenient than traditional ones.

比较对象为前文提到的复数“electric bikes”，代词及动词应与复数一致。原句用单数“it's”和“one”与复数主语不匹配。建议：代词与所指名词保持数的一致性，复数用“they/ones”。
