钥匙— Part 1 評分報告

建議: 回答不自然且信息不完整。句子断裂，语法有误（如“I go back home”与问题无关），缺少连接词和具体细节。应直接回答并给出简短原因，使用连贯句子（最多5句），注意时态和主谓一致。

範例: No, I don't usually carry many keys. I mostly use a fingerprint lock at home, so I only need one spare key when necessary. Because of the biometric system, I rarely worry about unlocking the door.

建議: 表达时态混乱（“Yes I do”与随后过去事件冲突），句子结构不够清晰。应直接说曾经丢过，说明时间、原因或结果，用连接词使逻辑清楚。

範例: Yes, I once lost my keys last year and felt very scared. I searched everywhere for an hour before finding them in my bag, so now I keep a spare key with a friend.

建議: 回答含混且语法错误频繁，信息不明确（“I've got my case”意思不清）。要直接回答频率并给出具体例子或原因，使用连贯表达并修正语法。

範例: Sometimes I do forget my keys; it has happened a few times when I left them on the kitchen table. After that I started leaving a spare key with my neighbour to avoid being locked out.

建議: 回答简短但缺少理由和细节，语法错误（应为"This is not a good idea"），可以给出理由并用连接词支持观点，拓展到安全或信任层面。

範例: No, I don't think it's a good idea because it can be risky if the neighbour moves out or if you don't know them well. Instead, I prefer leaving a spare with a trusted family member or using a secure key box.

× I go back home.

✓ I go back home.

无需修改。句子使用一般现在时描述习惯性动作，语法正确。

× I use the fingerprints.

✓ I use my fingerprint.

原句中 use the fingerprints 听起来不自然且冠词和名词形式不当。指纹通常用单数或不可数形式并与所有格连用。建议改为“I use my fingerprint”或“I use my fingerprints”。在中文：指纹通常说“我的指纹”，不要用定冠词“the”加复数。

× Yes I do, I was scared I have once lost my key.

✓ Yes I have. I was scared — I once lost my key.

原句混用了现在时和现在完成时且时序不清。回答“Have you ever lost your keys?”应使用现在完成时（I have）。随后描述过去的感受用一般过去时（I was scared）。建议把句子拆成两部分：先用现在完成时肯定回答，再用过去时描述具体感受或经历。中文解释：不要在同一句里混用现在完成时和现在时/过去时，要根据时间先后选择时态。

× Yes I do, I have few times I've got my case so I locked my door outside.

✓ Yes I have. A few times I left my case and locked myself out.

原句时态混乱且词序和词汇使用不当。回答“Do you often forget the keys and lock yourself out?”应使用现在完成或现在时的一般描述（I have / I do sometimes）。原句中的 "I have few times I've got my case" 不合语法，建议改为“A few times I left my case”或“I have locked myself out a few times”。中文解释：注意使用合适的时态和固定表达（lock oneself out = 把自己锁在外面），并把次数短语放在句首或句末以保持语序正确。

× No, I don't think so. This not good idea.

✓ No, I don't think so. That's not a good idea.

原句缺少系动词并且定冠词/不定冠词使用错误。正确表达应为“That is not a good idea”或缩写“That's not a good idea”。中文解释：需要使用系动词（is/ 's）并使用不定冠词“a”与可数名词“good idea”。
