Machine— Part 1 採点レポート

提案: 回答较直接，信息相关但表达有词汇与语法小问题，且句子可以更自然、更连贯。建议：1) 使用更自然的词汇，如 'vacuum cleaner' 而不是 'vacuum'；2) 开头用主题句清晰回应问题，然后用原因和具体场景支持（不要超过5句）；3) 注意冠词和复数形式，以及连接词（because / so / therefore）以增强连贯性。示例改进点：把两句合并并用连接词，补充具体细节（多久用一次、什么时候或怎样帮助过你）。

例: My favourite machine at home is the vacuum cleaner. I have a dust allergy, so I use it often to remove dust from my bed and desk, which helps reduce sneezing and makes it easier to sleep.

提案: 回答内容包含要点，但有重复和表达不够精炼之处。建议：1) 首句直接回答并总结观点；2) 用连接词（for example, moreover）组织支持句；3) 提供更具体的好处（time-saving, efficient water use）和对比（手洗 vs machine）；4) 注意词汇搭配（washing machines for clothes, dishwashers for dishes, robotic vacuums for corners）。

例: Yes, they are very important. For example, washing machines and dishwashers save a lot of time and water compared with hand-washing. Moreover, robotic vacuum cleaners can reach corners and save effort, so they make household chores much easier.

提案: 回答诚恳但表达略显啰嗦，且可以更自然地解释原因和后果。建议：1) 用一两句直接说明个人习惯，然后用连接词补充理由；2) 避免重复短语（'read the instructions' 多次出现），用代词或同义替换；3) 提供具体情景或例子说明风险或好处。

例: I rarely read manuals myself; instead, I ask my parents to explain the instructions to me so I can avoid mistakes. This usually works well because they point out important safety steps and settings.

提案: 回答完整且有例子，逻辑清晰，但有小语法和措辞问题（'cannot only' 应为 'not only'；'read the instruction' 应为 'read the instructions'）。建议：1) 开头用明确观点；2) 使用正确的固定搭配（not only... but also...）；3) 在例子中补充具体预防了哪类危险或学到了什么安全措施。

例: Yes, it is important. Not only do instructions explain how to operate a machine, but they also warn about potential dangers. For example, when I bought a washing machine last summer, reading the manual helped us learn the correct installation and avoid an electrical hazard.

× My favorite machine is vacuum, which is really important for me.

✓ My favorite machine is the vacuum, which is really important for me.

句中“vacuum”指代特定的家用机器，应使用定冠词“the”来表示特定的事物。建议在可数名词单数前使用“a/an”或“the”，当提到特定已知物时用“the”。

× I am allergic to dust, so I need to clean the dust on my bed and desk by using vacuum.

✓ I am allergic to dust, so I need to clean the dust on my bed and desk by using the vacuum.

同样，“vacuum”作为可数名词需加定冠词“the”。此外介词“on my bed and desk”是可以的，但更自然的表达是“on my bed and at my desk”或直接“from my bed and desk”。建议注意可数名词与介词搭配的自然用法。

× Washing dishes and clothes are both daily things in one home.

✓ Washing dishes and washing clothes are both daily tasks in a home.

原句中“clothes”与“washing”搭配不一致，且“things”用法不准确，应使用“tasks”或“chores”。注意保持并列结构中的形式一致（两项都用动名词短语），并用更恰当的名词替换泛化的“things”。

× If people use machines, it can help people to save energy.

✓ If people use machines, they can save energy.

条件句中主句主语应与动词一致。原句中主句用“it can help people to save energy”显得冗长且主语“it”与复数“people”不一致。可将主句主语改为“they”直接与前面的“people”保持一致，表达更简洁自然。

× As for sweeping machines, they can clean the dust in the corner.

✓ As for sweeping machines, they can clean the dust in the corners.

“the corner”通常指单一具体角落，而泛指家中各个角落应使用复数“corners”。根据上下文，建议用复数以表达一般性。

× Now I hardly ever read the instructions.

✓ Now I hardly ever read the instructions.

句子本身语法正确，保持现在时态表述当前习惯性动作即可，无需改动。此处仅确认为正确使用现在时。

× However, I usually ask my parents to read the instructions and tell me how to use the machine, which can avoid some mistakes when using the machine.

✓ However, I usually ask my parents to read the instructions and tell me how to use the machine, which can help me avoid some mistakes when using it.

关系代词“which”应指代整个前面的行为或事实，后面的动词结构“avoid some mistakes”需要有逻辑主语，使用“help me avoid”更自然。此外重复使用“the machine”冗余，使用代词“it”更简洁。

× Yes, it's very important to read the instructions of machines, because they cannot only explain the steps of machines, but also can help us prevent some dangerous accidents.

✓ Yes, it's very important to read the instructions for machines, because they not only explain the steps, but also help us prevent dangerous accidents.

介词搭配应为“instructions for machines”或“instructions for a machine”。“cannot only”用法错误，应为“not only... but also...”。同时“explain the steps of machines”冗长，直接说“explain the steps”更自然；“can help us prevent some dangerous accidents”中“some”可省略，整体更简洁。

× For instance, last summer holiday I bought a washing machine.

✓ For instance, last summer I bought a washing machine.

短语“last summer holiday”在英语中不自然，通常说“last summer”或“during the summer holiday”。此外句子时态和结构正确，应将时间状语改为常用表达“last summer”。

× My parents and I read the instruction before using it.

✓ My parents and I read the instructions before using it.

“instruction”在此应为可数复数形式“instructions”。表示使用机器前阅读说明书通常是复数形式。注意可数名词单复数的正确使用。
