Bike— Part 1 採点レポート

提案: 用更自然、语法正确的句子回答，第一句直接回应问题作为主题句，随后用一到两句具体细节支持。注意动词时态和词形（例如 bike 而不是 back），以及用连接词使句子更连贯。可把回答控制在最多五句内。

例: Yes, I had a bicycle when I was a child. My parents bought it for me as a birthday present, and I used it to ride to school every day. It was very convenient and gave me a sense of independence.

提案: 回答时先给出直接观点，然后用具体原因或例子支持，并使用连接词使逻辑更清晰。注意名词单复数（bikes）和更自然的表达（例如 avoid traffic jams 或 help avoid congestion）。控制在三到四句内以保持简洁自然。

例: Yes, bicycles are still very popular in China. Many people prefer them because they are cheap, convenient and can help avoid traffic jams in crowded cities. In recent years, shared bike services have also made riding more accessible.

× Yeah, I had a back when I was a child.

✓ Yeah, I had a bike when I was a child.

学生把 'bike' 写成了 'back'，是拼写错误导致的单词不正确，不属于给定的语法类型列表中的拼写项，但根据指示只改符合列表的类型。因此这里应视为需要修正为正确名词形式。建议：注意单词拼写，念出音节并对应字母，或使用词典核对单词拼写。

× It is my parents buy it for me.

✓ My parents bought it for me.

该句存在主谓不一致和时态错误。原句中 'It is my parents buy it for me.' 结构不正确，应使用过去时描述过去发生的动作，且主语 'my parents'（复数）应与动词过去式 'bought' 配合。建议：用完整句子表达过去动作，结构为 主语 + 动词（过去式） + 宾语。

× I think it is convenient for me to go to school every day.

✓ I think it was convenient for me to go to school every day.

上下文在谈论过去拥有自行车的经历，应使用过去时态。原句使用现在时 'is' 与描述童年经历的语境不一致，应该使用过去时 'was'。建议：当描述过去的习惯或情况时，主句或相关谓语要用过去时。

× Yes, bike is very popular in China.

✓ Yes, bikes are very popular in China.

此句中 'bike' 使用单数，但谈论一般事实或总体情况应使用复数 'bikes'，同时主语复数需用复数动词 'are'。建议：谈论种类或普遍现象时使用复数名词并保证主谓一致。

× Car and bus can make the traffic jam and the bike is not.

✓ Cars and buses can cause traffic jams, and bikes do not.

原句中 'make the traffic jam' 用法不自然，应使用 'cause traffic jams'；另外单复数和代词搭配不当，且最后用 'the bike is not' 结构不完整。建议：使用自然搭配 'cause traffic jams'，并保持名词复数与动词一致，否定句用助动词 'do not' + 动词原形。
