Machine— Part 1 채점 보고서

제안: 用词和语法需要更准确，避免说错词（如把“machine”说成“emotion”），注意时态一致，简洁表达并使用连接词使逻辑更清晰。可以将回答控制在3-4句内，第一句直接回答问题，随后用一两句具体说明理由并给例子。

예시: My favourite machine at home is the humidifier. I fill it with water every night before bed because it makes the air more comfortable and helps me sleep better. For example, when the air is dry I often wake with a sore throat, but the humidifier prevents that.

제안: 总体不错，内容具体且有比较，但可改进为更自然的连接词并避免重复（如“much, much”）。可把观点和理由更紧密结合，并用一两个具体例子提升说服力。

예시: Yes, I do. Washing machines save a lot of time and clean clothes more thoroughly than hand-washing, especially for large loads. Robotic vacuums are useful for reaching corners and under furniture, so they keep the house tidy with minimal effort.

제안: 回答有重复和未完成的句子，要注意句子完整且避免赘词。可以给出具体细节说明读说明书的哪些部分（如安全、清洁、操作步骤），并用正确时态和流畅连接。

예시: Yes, I always read the manual. I pay attention to safety warnings, operating steps and cleaning instructions, especially for complex appliances like my new coffee machine, so I can use it safely and keep it in good condition.

제안: 表达清晰但有一些语法错误和重复（如“relevant clean cleaning”）。注意主谓一致和单复数，使用连接词使句子更紧凑。可以加一个简短例子说明读说明书如何延长设备寿命。

예시: Yes, I believe reading instructions is important because they explain safety precautions and proper cleaning procedures. For instance, following the recommended cleaning routine for a blender can prevent damage and extend its lifespan.

× My favorite emotion in my home is the humidifier.

✓ My favorite appliance in my home is the humidifier.

原句使用了“emotion（情感）”一词，但语境中应该是指“家用电器（appliance）”。这是词类选择错误，属于形容词/副词或词汇使用不当的范畴。建议牢记常见家庭设备的词汇（如appliance, device, machine），并在说话前快速确认所用单词是否符合语境。

× I pour water into it every day before I went to sleep because umm the more it helps me feel relaxed and umm give me and make me sleep much better at night.

✓ I pour water into it every day before I go to sleep because it helps me feel relaxed and makes me sleep much better at night.

问题类型：6: 现在时问题（Present tense issue）和27: 主谓一致（Subject-verb agreement）混合。原句中时态混用（前半句用现在时“I pour... before I went”应统一为现在时），且后半句主语与动词不一致（“it... give me and make me”应为“it helps... and makes me”）。建议：保持时态一致，主语单复数与动词形式一致。把所有表示习惯性动作的动词用一般现在时，并确保动词加-s（第三人称单数）时正确。

× the more it helps me feel relaxed and umm give me and make me sleep much better at night.

✓ the more it helps me feel relaxed and makes me sleep much better at night.

原句中复合谓语部分主语是单数it，但动词部分使用了不带-s的原形动词（give, make），与主语不一致。应使用第三人称单数形式（gives, makes）或与前半句保持结构一致，这里用makes更自然。建议：遇到第三人称单数主语时，给动词加-s。

× Washing machines can do a much, much more thorough cleaning work and save us a lot of time.

✓ Washing machines can do much, much more thorough cleaning and save us a lot of time.

原句中搭配“thorough cleaning work”不自然，通常说“thorough cleaning”或“a much more thorough job of cleaning”。多余的介词/名词搭配错误属于介词或搭配使用问题。建议使用常见搭配：'thorough cleaning'或'a more thorough job'。

× And the robotic vacuum can clean those hard to reach areas, which is quite convenient for me.

✓ And the robotic vacuum can clean those hard-to-reach areas, which is quite convenient for me.

“hard to reach”作为复合形容词修饰名词时应连字符连接作形容词短语“hard-to-reach areas”。这是形容词用法的细节问题。建议：当多个词共同作前置定语时，考虑加连字符以提高表达准确性。

× Especially for complicated machines such as a coffee machine, which I recently bought. I read it very read the instructions very carefully so that I know about the.

✓ Especially for complicated machines such as a coffee machine, which I recently bought, I read the instructions very carefully so that I know how to use it safely.

原句存在句子结构不完整和重复（'I read it very read the instructions'）以及句尾不完整（'so that I know about the.'）。这是句子结构错误。建议：合并断裂的句子，删除重复部分，并补全宾语或从句（如'how to use it safely'）。

× Yes, I think instructions are quite essential because it helps you to know the basic safety warnings to avoid accidents and also it give you guidance about the relevant clean cleaning procedures, for example, so that it lasts longer.

✓ Yes, I think instructions are quite essential because they help you to know the basic safety warnings to avoid accidents and also give you guidance about the relevant cleaning procedures, for example, so that it lasts longer.

句中存在代词与先行词不一致（'instructions'为复数但用了单数代词'it'，属于代词使用错误/主谓一致问题），以及'mixed'动词形式（'it give'应为'they give'）。另外有重复词汇('clean cleaning')。建议：将代词与先行词数一致；避免重复；确保动词与主语一致。
