Bike— Part 1 채점 보고서

제안: 句子语法和时态使用不准确，且回答过于简短、缺乏细节。建议用正确的过去时表达，并给出一到两个具体原因或例子来丰富答案。连词和句子结构可更自然，例如用“because”引出原因后加上具体情况。

예시: No, I didn't have a bike when I was a child because my parents thought it was unsafe for me to ride on busy roads. For example, I usually took the bus to school and sometimes walked with my brother.

제안: 回答总体方向正确，但表述含糊且不够具体。注意主语和代词的搭配（例如 use "they" 或 "bicycles" 而不是 "it"），并给出具体原因、数据或对比来支持观点。使用连接词（e.g., "because", "for example", "moreover"）使答案更连贯。

예시: Yes, I think bicycles are quite popular in my country because many people use them for short commutes and exercise. For example, in big cities you can see bike lanes and many commuters cycle to work, which is cheaper and often faster than driving during rush hour.

× No, I didn't because I don't like bicycle when I was a child.

✓ No, I didn't because I didn't like bicycles when I was a child.

此句存在时态和可数名词问题（主要按“现在时/过去时”归类为“现在时问题”或更确切为过去时，但根据列表选择“Present tense issue”）。原句中主句用过去时“didn't”，从句却用了现在时“don't”，时态不一致，应使用过去时“didn't like”。另外，名词“bicycle”作为可数名词在泛指时应使用复数形式“bicycles”或在前加冠词（a bicycle）。改正为“didn't like bicycles when I was a child.” 建议：当主句使用过去时间背景（when I was a child）时，所有描述该时期的动词应使用过去时；泛指可数名词用复数或不定冠词。

× Yes, because it's a nice choice for going to work or having a rest. It can relax ourselves.

✓ Yes, because it's a nice choice for going to work or for resting. It can relax us.

原句有两个问题：1) “having a rest” 在此语境可更自然表述为“resting”或“have a rest”，并且前面应保持平行结构，使用“for going to work or for resting”。2) 代词使用错误，“ourselves”是不反身代词，用于动作返回给动作发出者的情况，而此处应使用宾格人称代词“us”。因此改为“It can relax us.” 建议：选择与句子主语/客体一致的人称代词；保持并列短语时结构平行。
