Bike— Part 1 채점 보고서

제안: 用简单正确的时态和更连贯的句子表达童年经历。注意时态一致（过去式），减少口头语（uh, umm），并用连接词使描述更流畅和具体。例如可以先给出主题句，然后补充具体细节（什么时候、谁送的、做了什么、感受如何）。

예시: Yes, I had a bike when I was a child. My parents bought it for me on my seventh birthday, and I was very excited. I used it to ride to the park every Sunday, and it gave me a lot of happy memories because I often rode with my friends.

제안: 回答要更完整并使用连接词来组织原因和比较，避免句子未完成。可给出具体例子或比较对象（比如公交或开车），并使用更恰当的词汇（commute, convenient, economical）。

예시: Yes, bikes are still popular in China. Many people use them to commute because cycling is economical and often faster than driving in busy urban areas. For example, riding a bike can save time during rush hour compared with taking a car or bus.

× Yes, I actually have a bike when I'm young.

✓ Yes, I actually had a bike when I was young.

原句中使用了现在时态“have”和“I'm young（I am young）”，但句子描述的是过去情况。应使用过去时“had”和“was young”。建议：讲述过去经历时，一律将动词改为过去时，be动词用 was/were。

× At that time, I'm excited that my parents brought it to me and it truly accompanied me and I have a lot of happy time at uh, that time.

✓ At that time, I was excited that my parents had brought it to me, and it truly accompanied me; I had a lot of happy times then.

原句混用现在时和过去时（“I'm excited”、“brought”是过去时但与现在时混用），且时态和时序不一致。应将情感和经历都用过去时：was excited、had brought（或brought）以保持时序一致。另一句“have a lot of happy time”应为过去时复数“had a lot of happy times”。建议：复查句中所有动词时态，叙述过去事件时保持过去时一致，注意可数名词复数形式。

× Umm and I use it to, to go outside on Sunday.

✓ Umm, and I used it to go out on Sundays.

原句中“use”使用了现在时，但叙述的是过去习惯，应为过去时“used”。另外“go outside on Sunday”不自然，常用短语是“go out on Sundays”（表示过去的经常性行为用复数）。建议：描述过去经常性动作用过去时和复数时间表达（Sundays）。

× Yes, because in China many people go to work by bikes.

✓ Yes, because in China many people go to work by bike.

句中时态“go”是一般现在时，适用于陈述普遍事实，这里时态正确。但问题在于名词形式，短语应为“by bike”（不可数或单数形式），不能用复数“bikes”。建议：固定搭配“by + 交通工具（单数/不可数）”。

× That's not only because it's cheap, but because it saves time and energy.

✓ That's not only because it's cheap, but also because it saves time and energy.

原句缺少“also”来完成“not only ... but also ...”的平行结构，使句子不完整。建议：使用固定结构“not only ... but also ...”，保持并列部分平行。

× I think it's very convenient in comparison with.

✓ I think it's very convenient in comparison with other ways of transport.

原句不完整，比较对象缺失，导致句子结构不完整。需补上比较对象，如“other ways of transport”或“cars and buses”等。建议：使用比较结构时明确比较对象，避免留下句子未完成。
