Bike— Part 1 채점 보고서

제안: 回答要更自然、语法更准确，并避免填充词（uh, umm）。开头一句可直接点明主题，然后用一两句具体细节（如谁买的、几岁、常去哪儿骑、感受）支撑。注意时态和搭配（如 say “I liked sports” 或 “I was very into sports”；用 “I used to ride my bike on weekends”）。总体保持不超过5句。

예시: Yes, I did. My mother bought me a bike when I was six because I was really into sports. I used to ride it almost every weekend around my neighborhood with my friends, which helped me build confidence and stay active.

제안: 回答要更具体并使用连贯词来丰富信息。开头直接回答，然后给出具体原因、例子或对比（如城市与乡村的差异、共享单车的影响）。注意语法（复数/单数和搭配：'people often commute to work or school by bike'，'bikes are'）。保持不超过5句。

예시: Yes, they are. Many people in China commute to work or school by bike because it is cheap and convenient. In recent years, the rise of bike-sharing services has made cycling even more common in cities, although cars are more popular in rural areas.

× Yes, I had a bike when I was a child.

✓ Yes, I had a bike when I was a child.

句子原本为过去时态，语法正确，无需更改。保持过去时与提问（过去时）一致。

× Uh, I remember when I was six years old my mom bought me a bike because I very like sport.

✓ Uh, I remember when I was six years old my mom bought me a bike because I really like sports.

原句中使用了不正确的副词搭配“very like”，英语中“like”需要用副词“really”或“really enjoy”等来加强语气；此外“sport”作可数时常用复数形式表示兴趣爱好（sports）或用动名词形式（playing sports）。建议用“really like sports”或“really enjoy playing sports”。说明（简体中文）：“very like”不是正确搭配；将其改为“really like”并把“sport”改为复数或改为动名词形式更地道。

× So I usually, umm, biking on the weekend.

✓ So I usually, umm, bike on the weekend.

此句需要动词原形而非现在分词。带频率副词（usually）和一般现在时描述习惯时，用动词原形（I usually bike）。若要用动名词形式需搭配正确的助动词或结构（e.g. I usually go biking）。说明（简体中文）：将“biking”改为动词原形“bike”，或改为“go biking”。

× Yes, in China people often go to go to work or school by bike.

✓ Yes, in China people often go to work or school by bike.

原句有重复短语“go to go to”。删除重复部分，保留一般现在时陈述习惯的正确结构：people often go to work/school。说明（简体中文）：去掉多余的“go to”，保持一般现在时描述常态用法。

× Bike is very convenient and popular in China.

✓ Bikes are very convenient and popular in China.

此句在泛指复数名词时应使用复数形式或使用不定冠词加单数。单数“Bike is”不合语法。改为复数“Bikes are”以表达“自行车（复数）很方便且受欢迎”。同时主谓一致需把“is”改为“are”。说明（简体中文）：泛指事物用复数（Bikes are）或用定冠词/不定冠词（A bike is）来表达；这里用复数更自然。
