自行车— Part 1 評分報告

建議: 回答要更自然且语法正确。可把句子分为主题句和补充句，避免冗长或重复；注意时态和代词的一致性；补充具体细节（例如什么时候、谁给的、喜欢骑到哪里）来丰富内容。

範例: Yes, I did. My parents bought me a small pink bicycle when I was six, and I loved riding it around the neighborhood every afternoon.

建議: 回答总体清晰，但可更自然地组织信息并加入比较或原因来增强内容连贯性。使用连接词（for example, because, so）使论述更有逻辑，并提供具体例子或数据。

範例: Yes, bikes are very popular in my country, mainly because shared-bike services are widespread. For example, you can find hundreds of public bikes on city streets; you just scan a QR code to unlock one and pay a small fee, which makes cycling convenient and affordable.

× Yes, of course I had back when I was were a child, my parents bought very cute one.

✓ Yes, of course I had one when I was a child; my parents bought a very cute one.

句子有多处过去时和结构问题： 1) 原句中出现了“was were”是冗余且冲突的动词形式，正确应为单一过去式“was”。 2) “had back when I was a child” 顺序不自然，改为“had one when I was a child” 更符合英语习惯。 3) “my parents bought very cute one” 缺少不定冠词“a”，并且应与前句用分号或句点分开以避免 run-on sentence（并列连写句）问题。 改进建议：使用单一过去式动词，注意冠词 a/an 的使用，并把长句拆分或用合适标点连接。

× It is pink and I really like riding it.

✓ It was pink and I really liked riding it.

句子讲的是过去拥有的自行车，时态应与上下文一致使用过去时： 1) “It is pink” 使用一般现在时，但语境为过去，应改为“was pink”。 2) “I really like riding it” 同理改为过去时“liked”。 改进建议：描述过去经历时，全句保持过去时，避免时态混用。

× Yes, bikes are very popular in my country and there are many bikes in the street which is public for everyone.

✓ Yes, bikes are very popular in my country, and there are many bikes on the streets that are available to the public.

主要时态问题与介词/从句表达： 1) 原句“in the street” 表示具体某条街，若泛指街道应使用复数“on the streets”。 2) “which is public for everyone” 从句结构和词语选择不自然，改为“that are available to the public” 更清晰正确。虽然整体时态现在时可以成立（陈述现在事实），但句子中也涉及介词和从句的错误，故此处主要按现在时修正并同时改正介词及定语从句。 改进建议：注意表示一般事实时使用现在时一致；使用正确介词（on the street(s)）并用定语从句清晰修饰名词。

× If you want to ride it, you just need to scan the QR code and then pay for it.

✓ If you want to ride one, you just need to scan the QR code and then pay for it.

句子总体时态为一般现在用于说明现在的习惯或步骤，时态本身可接受。但存在指代不清： 1) 前文提到“many bikes”，此处应使用不定代词“one”代替“it”来指一辆共享单车，避免混淆。 改进建议：在描述操作步骤时使用一致的现在时，并保持代词指代清晰（用 one 指代单个物品）。
