Bike— Part 1 채점 보고서

제안: 回答基本切题，但时态和语法错误较多。过去的经历应使用一般过去时，例如将“haven't have”改为“didn't have”，将“I'm not good”改为“I wasn't good”，将“haven't buy”改为“didn't buy”。另外，避免重复“when I was a child”和自我修正；可以先直接回答，再用一个清晰的原因补充。建议使用“because”连接原因，并说明你不擅长骑车，所以没有买自行车。

예시: No, I didn’t have a bike when I was a child. I wasn’t very good at riding, so I didn’t ask my parents to buy me one. Instead, I usually walked to school or played with my friends nearby.

제안: 回答观点明确，也提供了共享单车这一具体例子，但句子过长，结尾“scan the QR card to”不完整，应该说“scan a QR code to unlock a bike”。建议使用“especially”或“for example”组织信息，并补充共享单车受欢迎的原因，如价格便宜、方便且环保。注意“our country set up”可改为“bike-sharing services have been introduced”或“the government has introduced bike-sharing services”。

예시: Yes, bikes are quite popular in my country, especially in big cities. In recent years, bike-sharing services have become common, so people can scan a QR code to unlock a bike. They are popular because they are convenient, affordable, and environmentally friendly.

× No, I haven't have a bike when I was a child because when I was a child I don't I I'm not good at bicycles, so I haven't buy a bike.

✓ No, I didn't have a bike when I was a child because I wasn't good at riding bicycles, so I didn't buy one.

问题类型是过去时错误。句子描述的是童年时期的经历，应该使用一般过去时。将“haven't have”改为“didn't have”，“I don't / I'm not”改为“I wasn't”，并将“haven't buy”改为“didn't buy”。注意：描述过去发生并已经结束的事情时，应使用一般过去时，而不是现在完成时。

× No, I haven't have a bike when I was a child because when I was a child I don't I I'm not good at bicycles, so I haven't buy a bike.

✓ No, I didn't have a bike when I was a child because I wasn't good at riding bicycles, so I didn't buy one.

“be good at”中的“at”是介词，介词后面接动词时，动词要使用-ing形式。因此，“good at bicycles”应改为“good at riding bicycles”。建议记住固定搭配：“be good at + 名词/动词-ing”。

× Yeah, I think bikes are very popular in our country and in recent years our country set up the bike share for everybody and if people want to go anywhere they can scan the QR card to.

✓ Yeah, I think bikes are very popular in our country, and in recent years, our country has set up a bike-sharing system for everybody. If people want to go anywhere, they can scan a QR code to unlock a bike.

“in recent years”表示从过去持续到现在的时间段，通常使用现在完成时。因此，“set up”应改为“has set up”。现在完成时的结构是“has/have + 过去分词”；主语“our country”是第三人称单数，所以使用“has”。

× Yeah, I think bikes are very popular in our country and in recent years our country set up the bike share for everybody and if people want to go anywhere they can scan the QR card to.

✓ Yeah, I think bikes are very popular in our country, and in recent years, our country has set up a bike-sharing system for everybody. If people want to go anywhere, they can scan a QR code to unlock a bike.

第一次提到一个可数单数事物时，通常使用不定冠词“a/an”。这里应该说“a bike-sharing system”和“a QR code”，而不是“the bike share”和“the QR card”。“the”通常用于双方都知道或前面已经提到过的特定事物。

× Yeah, I think bikes are very popular in our country and in recent years our country set up the bike share for everybody and if people want to go anywhere they can scan the QR card to.

✓ Yeah, I think bikes are very popular in our country, and in recent years, our country has set up a bike-sharing system for everybody. If people want to go anywhere, they can scan a QR code to unlock a bike.

句子最后的“to”后面缺少动词，导致句子结构不完整。“to”后面需要接动词原形，例如“to unlock a bike”。此外，原句包含多个连接在一起的分句，建议用逗号和句号分开，使句子更清楚。
