Machine— Part 1 採点レポート

提案: 回答中存在语法错误和表达不自然的问题，例如“sing his piano”应为“sing on his piano”或“play the piano”。建议注意动词使用和时态一致性，同时避免冗余表达。

例: My favourite machine at home is the piano because I love playing it. My mother bought it when I was a little girl, and I used to play it every day during high school to relax.

提案: 回答中存在重复和语法错误，如“it's a very useful machine”应改为“they are very useful machines”。建议使用复数形式并丰富细节，避免简单重复。

例: Yes, I think washing machines and sweeping machines are very important because they help save time and effort, especially for my mother who cleans the house regularly.

提案: 回答中语法错误较多，表达不清晰。建议学习正确的句子结构，使用连词使表达更连贯，并具体说明阅读说明书的原因。

例: Yes, I always read the instructions before using a machine because some machines are complicated. Reading the manual helps me understand how to operate them correctly and saves time.

提案: 回答中存在语法和表达不准确的问题，如“structure”应为“instructions”。建议注意词汇准确性，句子结构清晰，并用连词连接句子。

例: Yes, I think it is important to read the instructions because when you buy a new machine, you might not know how to use it. Instructions can guide you and make it easier to operate the machine.

× Oh well, I sing his piano because I love playing piano very much.

✓ Oh well, I play his piano because I love playing piano very much.

这里'sing'是错误的动词，应该用'play'来表示弹钢琴。'sing'表示唱歌，与弹钢琴的动作不符。

× so when I'm in Senior High School, I played piano every day to relax myself.

✓ so when I was in Senior High School, I played piano every day to relax myself.

句子中描述过去的动作，应该用过去时态，'I'm'应改为'was'。

× I think it's a very useful machine to help someone to clean our room, especially my mother.

✓ I think they're very useful machines to help someone clean our room, especially my mother.

提到多个机器（washing machines and sweeping machines），应使用复数形式'machines'，并且谓语动词和指示代词也应对应复数。

× Because my mother often cleans our room, using this machine is useful for her.

✓ Because my mother often cleans our room, using this machine is useful to her.

'useful for'和'useful to'都可用，但在表达对人的有用时，'useful to'更常见且自然。

× Yes, I read each time because some machines I don't understand how to use it.

✓ Yes, I read each time because for some machines I don't understand how to use them.

'some machines'是复数，后面指代应使用复数代词'them'，而不是单数'it'。

× The adjusters can help me how to use it and don't waste more time to use it.

✓ The adjusters can help me how to use it and help me not waste more time using it.

'don't waste more time to use it'结构不正确，应改为'help me not waste more time using it'，更符合英语表达习惯。

× Yes, of course, because structure is useful way to help someone when they buy the new machine, they maybe don't know how to use it at the beginning.

✓ Yes, of course, because instructions are a useful way to help someone when they buy a new machine; they may not know how to use it at the beginning.

'structure'应为'instructions'，且'instructions'为复数，谓语动词也应相应调整。'maybe'应为'may be'，表示可能。

× So when you have a instructions can help you.

✓ So when you have instructions, they can help you.

'instructions'是复数，前面不应加不定冠词'a'，且句子缺少主语谓语，应补充完整。
