自行车— Part 1 評分報告

建議: 语法和时态错误较明显，句子不自然且信息量很少。应使用正确的过去时态并给出一到两句具体补充说明（比如谁送的、经常在哪里骑、是否喜欢）。保持句子简短且连贯。示例改进要点：使用过去时（had/was）、主谓一致，开头一句直接回答，随后用因为/所以等连接词补充细节。

範例: Yes, I had a bike when I was a child. My parents bought it for me as a birthday present, and I rode it around the neighborhood almost every day.

建議: 表达较清晰但有词汇和搭配错误（如“bike struggling service”不合适，“walk over school”意思不明确）。建议用更准确的词汇（bike-sharing service, commute to school）并加一到两句具体例子或比较，以增加信息量和自然度。使用链接词（for example, moreover）使结构更连贯。

範例: Yes, bikes are very popular in my country because they are inexpensive and convenient for short trips. For example, many cities now have bike-sharing services, and I often see students commuting to school by bicycle in the morning.

× When I were a child, I have a bike.

✓ When I was a child, I had a bike.

语法问题类型 ID:27 主谓一致/时态错误。句中“When I were a child”主语“I”应与过去式单数“was”搭配，不能用“were”。另外，句子谈论过去的事情，谓语动词应使用一般过去时，“have”需改为过去式“had”。建议：学习be动词在不同人称和时态下的变化（I was/you were/he was 等），并把描述过去的动作用一般过去时。

× And many cities have bike struggling service now.

✓ And many cities now have bike-sharing services.

语法问题类型 ID:5 时态/词形错误。原句“bike struggling service”词序不当且单词错误，应为“bike-sharing service(s)”表示共享单车服务；句中使用“now”指现在时，谓语“have”可以保留，但要注意名词复数形式“services”更自然。建议：注意固定搭配“bike-sharing service(s)”并根据上下文选择单数或复数。

× For example, I often see people riding bikes to walk over school in the morning.

✓ For example, I often see people riding bikes to school in the morning.

语法问题类型 ID:11 介词使用错误。原句“riding bikes to walk over school”包含重复和错误的短语，“to walk over school”不符合英语表达。通常说“ride a bike to school”表示骑车去学校。建议：去某地使用固定搭配“go/ride/come to school”而不是“walk over school”。
