Bike— Part 1 채점 보고서

제안: 回答内容基本相关，但有语法、用词和连贯性问题。首先要用主题句直接回答问题，然后用1–2句具体补充理由或例子，最多不超过5句。注意时态一致（例如用‘I rode’或‘I used to ride’），纠正词汇错误（如“thick”应为“cheap”或“convenient”等），并使用连接词使句子更自然（for example, because, so）。可以删掉重复和无关信息以提高有效性。

예시: Yes, I did. I used to ride my bicycle to middle school because it was a convenient and cheap way to travel. It wasn’t very close to my home, so cycling saved me time and helped me stay active.

제안: 回答观点明确但表达含糊且有词汇和句法错误。先用一句话直接给出观点，然后用一两句具体理由和例子支持。注意词汇准确（例如“shared bikes”而不是“shared by”，“scan”而不是“scale”），避免重复（不要连续说“go to work or go to school”两次）。可用连接词（for example, moreover）使表达更连贯。

예시: Yes, I think bicycles are very popular in my country because cycling is a healthy and economical way to travel. For example, many people commute by bike, and there are convenient shared-bike systems you can unlock with a phone app.

× Yes, of course. I had a bike when I was very small.

✓ Yes, of course. I had a bike when I was very small.

句子时态正确，使用一般过去时描述过去拥有的状态，无需修改。

× I used to ride a bike to school when I was in the middle school because the school is not very far away from my home, but it's not close.

✓ I used to ride a bike to school when I was in middle school because the school was not very far from my home, but it wasn't very close either.

原句中描述过去的习惯应使用过去时（used to 已正确），但后半句混用了现在时（is/it's）。应将描述过去的距离也改为过去时（was/wasn't）。此外 “in the middle school” 非标准表达，应改为“in middle school”。“not very far... but not close” 表达不够自然，改为“not very far... but it wasn't very close either”。

× So I choose to ride a bike because it's a it's very thick and also it can save some time.

✓ So I chose to ride a bike because it was cheap and it also saved me some time.

句子讲述过去的决定，动词应使用过去时（choose → chose）。原句“it's a it's very thick” 是词汇和表达错误，应为“cheap”（便宜）或其他合理形容词；结合语境应为“cheap”。同时“can save some time”描述过去影响，应改为过去时“saved me some time”。此外去掉重复的“it's a”。

× Yes, bikes are quite popular in my country because it's a healthy way to go to work or go go to school.

✓ Yes, bikes are quite popular in my country because they are a healthy way to go to work or to school.

原句主句使用一般现在时正确，但代词“it's”指代不清且单复数不匹配，应使用复数代词“they”。重复“go go”是笔误，删去一个“go”。在列举不定式时保持平行结构，使用“to work or to school”。

× So many people will choose to ride a bike to go to their workplace or school place.

✓ So many people choose to ride a bike to go to their workplace or school.

原句中“will choose”可改为现在时“choose”表示习惯性事实更自然。短语“school place”不是地道表达，应简化为“school”。此外保持动词时态一致并简化表达。

× Also our country has shared by that everyone can write, you just use your phone to scale.

✓ Also our country has shared bikes that everyone can ride — you just use your phone to unlock one.

原句词汇和语法混乱。应把“shared by”改为“shared bikes”（共享单车）。“everyone can write”是笔误，应为“ride”。“you just use your phone to scale” 中“scale”不合适，推测意为“scan”或“unlock”。结合语境，用“use your phone to unlock/scan”更准确。保持时态为现在时描述普遍现象。
