自行车— Part 1 評分報告

建議: 注意发音与用词准确性（例如 bike 而不是 back, rear back 等混淆词）。回答要直接、简洁，保持不超过五句，并使用连词使表达更连贯。可以先用一句话直接回答问题，然后补充具体的细节或例子，例如说明为什么没有普通自行车、曾经拥有的四轮玩具车和何时会学骑车。避免重复和时态错误，时态应与叙述一致（过去时）。

範例: No, I didn't have a proper bicycle when I was a child. I wasn't good at riding, so my parents bought me a four-wheeled toy bike when I was very young. I could only ride that one safely, and I never learned to ride a regular two-wheeler until I was older.

建議: 注意词汇选择与拼写（应该是 "bike" 和 "public bike" 或 "bike-sharing"，而不是 back）。回答要先给出明确观点，然后用具体细节（例如共享单车的使用方式、便利性、城市普及率）支持观点，使用连接词如 "for example"、"because"、"as a result" 使条理清晰。控制句子长度，避免重复。

範例: Yes, bikes are very popular in my country, mainly because of bike-sharing services. For example, bike-sharing companies provide thousands of bikes that anyone can unlock with an app and pay a small fee, which makes cycling convenient for short trips. As a result, many people use bikes for commuting and running errands in cities.

× When I was a child I didn't have a back because I'm not good at riding bikes.

✓ When I was a child I didn't have a bike because I wasn't good at riding bikes.

原句把“bike”写成“back”，是拼写错误并造成句意不通；另外时态要一致，前半句为过去时（When I was a child I didn't have...），后半句也应使用过去时描述当时的能力（I wasn't good at riding）。建议注意单词拼写并保持时态一致。

× Actually when I'm when I was very, very young, I have a bike toy that is a bike with four wheels and I only can ride that one.

✓ Actually, when I was very, very young, I had a toy bike with four wheels and I could only ride that one.

句中存在时态混用：先用现在时“I have”与前面的过去时“when I was”冲突，应改为过去时“had”；情态动词也应使用过去形式“could”表示过去的能力；句子省略或重复的片段（"I'm when I was"）需删除多余部分。建议统一使用过去时并使用正确的情态动词。

× So I don't think I have a rear back when I'm a child.

✓ So I don't think I had a bike when I was a child.

原句有多处错误："rear back"非恰当搭配（应为"bike"），时态不一致（使用现在时描述过去，应为过去时），以及"when I'm a child"应改为过去时"when I was a child"。建议使用正确名词并保持时态一致。

× I think bikes are very popular in my country because you know that in China there is one thing called the public back, which means that there's a kind of bike that everyone can ride if they have enough credit and they only need to pay a very little amount of money and then they can write back for for a while.

✓ I think bikes are very popular in my country because in China there is something called the public bike (bike-sharing), which means there are bikes that everyone can ride if they have enough credit; they only need to pay a very small amount of money and then they can ride the bike for a while.

原句有拼写和用词错误（"public back"应为"public bike"或"public bike system"；"write back"应为"ride back/ride the bike"），并且部分复合句冗长、重复（"for for a while"）。建议纠正拼写、使用恰当名词并简化句子结构，保持主谓一致和语序自然。
