Keys— Part 1 採点レポート

提案: 回答总体清晰，但有语法和表达问题，影响自然度与准确性。应直接开门见山（简短主题句），然后用一两句具体细节支持。注意单数/复数和固定搭配（例如 “fingerprint-recognizing lock” 或 “fingerprint lock”），并减少冗长。可以加入衔接词以增强连贯性。

例: No, I don't carry keys because I use a fingerprint lock at home. It is more secure and convenient than traditional locks, so I never need physical keys.

提案: 回答有个人经历，内容相关且具体，但语法和时态混用、重复较多。建议先用一句明确的主题句交代曾经丢钥匙的事实，再用一两句具体细节说明后果与现在的变化。避免口头填充词（如 "uh"），调整时态一致。

例: Yes, I used to lose my keys frequently when I was in elementary school. Because of that my father often had to change the locks, but we later installed a fingerprint lock so I no longer worry about losing keys.

提案: 回答逻辑清楚且内容具体，但句子过长且信息密度高，影响流畅性。建议用一到两句分开表达：先回答是否发生过，然后说明应对方法及条件。注意简化从句并使用衔接词（e.g. "however", "if"）。

例: No, that has never happened to me. If I did lock myself out, building security would open the door for me after I contact them and show my ID.

提案: 回答考虑了不同情况，表现出判断力，但表达上有重复与语法错误（例如冠词和单复数问题），并有口头填充词。建议先给明确立场，再分别说明信任邻居的优点和现代替代方案，使用连接词如 "however"。

例: It depends. If you trust your neighbour, leaving a spare key with them can be convenient. However, these days building security often holds spare keys, so it may not be necessary.

× No, I don't bring any keys with me to anywhere because I own a fingerprint recognizable locks which are comparatively safe and convenient to traditional locks that we used in the past.

✓ No, I don't bring any keys with me anywhere because I have a fingerprint-recognizable lock, which is comparatively safer and more convenient than the traditional locks we used in the past.

类型编号：11（介词使用错误）、12（代词/所有格使用不当）、13（形容词/副词使用不当）、1（单复数问题）。问题包括："to anywhere" 中的介词 "to" 多余，应为 "anywhere"；"own a fingerprint recognizable locks" 中主语与名词不一致且词序不当，应为单数 "lock" 并用正确的定语顺序或连字符描述；缺少比较结构中的 "than"，且比较级形式要并列使用（safer and more convenient）。建议：去掉多余介词，确保名词单复数与动词/冠词一致，使用连字符连接复合形容词，并在比较中使用 than 或者使用并列比较级。

× Yes, when I was in elementary school I often lost our keys, which was really inconvenient because my dad had to replace the lock each time for our security.

✓ Yes, when I was in elementary school I often lost my keys, which was really inconvenient because my dad had to replace the lock each time for our security.

类型编号：12（代词使用不当）。原句中使用了 "our keys" 与后文的 "my dad" 和说话人的单人视角不一致，应使用 "my keys"。建议：保持人称一致，若谈论自己的经历用 "my"。

× Thankfully, uh, we now installed fingerprint lock.

✓ Thankfully, we have now installed a fingerprint lock.

类型编号：9（过去分词/完成时使用问题）。原句用简单过去 "installed" 与表示至今影响的语境不匹配，正确应使用现在完成时 "have installed"；并且 "fingerprint lock" 前加不定冠词 "a"。建议：表示从过去到现在的动作结果时使用现在完成时，注意冠词使用。

× I don't have to worry about losing my keys every time when I'm out.

✓ I don't have to worry about losing my keys whenever I'm out.

类型编号：20（副词位置/连词搭配错误）。原句中 "every time when" 冗余且不自然，可用 "whenever" 或者只用 "every time" 加从句结构。建议：用更自然的连接词 "whenever"，避免重复。

× This has never happened to me, but if it did it wouldn't be so much trouble for me because our building security keeps extra keys with them as long as I can contact them in time and they can open the door for me and when it's open I can show them the ID to prove this is my apartment.

✓ This has never happened to me, but if it did it wouldn't be much trouble because our building security keeps extra keys, as long as I can contact them in time and they can open the door for me; when it's open I can show them my ID to prove this is my apartment.

类型编号：26（句子结构错误）、11（介词使用/介词短语位置）和12（代词使用）。原句过长且结构混乱："wouldn't be so much trouble for me" 改为更简洁的 "wouldn't be much trouble"；"keeps extra keys with them" 中的 "with them" 多余且代词指代不清，应直接说 "keeps extra keys" 或 "has extra keys"；"show them the ID" 更自然为 "show them my ID"。建议：拆分长句，去掉多余的介词或代词，保持代词指代清晰。

× It really depends. You can leave an extra pair of key with your neighbors as you can trust them.

✓ It really depends. You can leave an extra pair of keys with your neighbors if you can trust them.

类型编号：1（单复数问题）、16（连词使用不当/条件连词）。原句中 "pair of key" 应为复数 "pair of keys"；连词 "as" 在这里易引起歧义，表示原因时可以，但更自然的是条件连词 "if"（如果你能信任他们）。建议：注意 "pair of" 后接复数名词，并用适当的连接词表达条件或原因。

× But nowadays it's not necessary because our building security or most of the building security in China carries an extra, uh, keys with them in case something bad happens.

✓ But nowadays it's not necessary because our building security, or most building securities in China, carry an extra key with them in case something bad happens.

类型编号：1（单复数问题）、11（介词使用）、12（代词/主谓一致）。问题包括：主语短语不一致导致动词数错误，应根据复数或集合使用 "carry" 而非 "carries"；"an extra, uh, keys" 冲突（冠词 a/an + 复数名词），应为 "an extra key" 或 "extra keys"；"with them" 可保留但要确保指代清晰。建议：保持主谓一致，冠词与名词数一致，必要时把主语短语改为明确的单数或复数以匹配动词。
