自行车— Part 1 评分报告

建议: 用更自然、时态正确的句子直接回答问题，控制长度并补充具体细节。注意语法（过去时）、冠词和复数形式，去掉填充词如“umm”。可以先给出主题句，然后用一两句讲具体年龄和经历，并用连词连接。

示例: Yes. I had two bikes when I was a child: one with training wheels and one without. I learned to ride when I was in third grade, so before that I always used the bike with training wheels.

建议: 先直接回答然后给出清晰具体的支持细节。注意词汇选择（用bikes而非 biker），句子要完整，说明共享单车的使用步骤时要逻辑清楚并用连接词。避免不准确或含糊的短语。

示例: Yes, bikes are very popular in my country. There are many public bike-sharing systems: after you register on the app you can unlock a bike, ride it around the city and return it to any designated station when you finish.

× Yes I do have 1 and I have two, one with the supporting wheel and one with not.

✓ Yes, I had one. I actually had two: one with training wheels and one without.

错误类型：现在时使用不当。学生在被问及“当你是小孩时（past）”应用过去时，但使用了现在时“do have”。改正建议：句子时态应与提问一致，使用过去时（had）。另外使用数字“1”不自然，改成“one”更合适；“supporting wheel”应使用更常见的短语“training wheels”；“one with not”语法错误，改为“one without”。建议：在描述过去发生的事情时始终用过去时，尽量使用常用搭配（training wheels），并用完整单词代替数字符号。

× But because I learned how to ride a bike umm when I was in 3rd grade, so before that I refused to ride the one without supporting wheel.

✓ But because I learned how to ride a bike when I was in third grade, I refused to ride the one without training wheels before that.

错误类型：过去时使用及句子结构问题。原句在时间顺序和连接词使用上不清晰：既用了“because... when...”又加“so”，造成冗余；“refused to ride the one without supporting wheel”中“supporting wheel”用词不自然且缺少复数。改正建议：简化连接词，保持过去时一致；使用“training wheels”和复数形式“wheels”。建议：用一个连词（because 或 so）并保持时态一致，名词复数要正确。

× Yes, biker is popular in my country and you can see the public bike everywhere and it's easy.

✓ Yes, bicycles are popular in my country. You can see public bikes everywhere, and they are convenient to use.

错误类型：名词和现在时表达不准确（归入现在时问题）。原句“biker is popular”错误使用“biker（骑手）”代替“bicycle（自行车）”；“the public bike”应为“public bikes”或“public bike system”；“it's easy”不明确，改为“they are convenient to use”。改正建议：使用正确的名词复数形式来表示普遍现象，并用清晰的形容词或词组描述便利性。

× You just whip a car in which called easy car and after you registered it on the app the public system and you can write it everywhere and return it when you see the.

✓ You just unlock a bike using an app (commonly called "easy bike"), register on the public bike system, you can ride it everywhere and return it when you see a station.

错误类型：多处词汇与冠词使用错误、句子结构混乱（涉及There be/文章及句子结构问题）。原句中“whip a car”错误词汇（应该是 unlock/unlock a bike 或 use an app），"in which called easy car"结构不正确；"after you registered it on the app the public system"时态及结构混乱；"you can write it everywhere"应为“ride it everywhere”；结尾“return it when you see the.”不完整，应补充“a station”或“a docking point”。改正建议：使用正确词汇（unlock/ride/register）、保持时态一致（一般现在时描述普遍事实）、补全句子并使用恰当名词（bike, station）。中文建议：多练习固定搭配如“unlock a bike”“register on the app”“ride it everywhere”“return it to a station”，注意主谓结构和句子完整性。
