自行车— Part 1 評分報告

建議: 句子有明显的时态、主谓一致和词汇错误，表达也不够连贯。建议： 1) 注意时态与主语一致（过去时）； 2) 使用更自然的连接词简洁组织信息（例如：When I was a child, ... Later,...）; 3) 修正词汇错误并补充少量细节以显得具体（例如：type of bike, age, reason for change）。 练习方法：写出两到三句完整的过去时回答，并大声朗读，同时录音回听纠正发音与语法。

範例: When I was a child, my mother bought me a small red bicycle and I loved riding it around the neighborhood. Later, when I started high school, I switched to a moped because I needed to travel farther to get to school.

建議: 语言不够准确，有词汇错误（"back"、"transfer away"），句子结构和表达稍显笨拙。建议： 1) 用准确词汇（bicycle, means of transport）替换错误单词； 2) 用连接词与具体数据或原因丰富回答（for example, because they are cheap and convenient）; 3) 保持句子简洁，避免重复。

範例: Yes, bicycles are very popular in my country, especially among middle and high school students. They are a common means of transport because they are inexpensive and convenient for short journeys to school.

× Yes umm when I'm children my mom buy a bike for me and I love it very much and then when I go to the high school I changed the bike to a MO motor.

✓ Yes. Umm when I was a child my mom bought a bike for me and I loved it very much, and then when I went to high school I changed the bike to a motorbike.

错误类型：代词与时态/主语不一致（属于代词与主语的使用问题，列入“Incorrect use of pronouns”）。 原因与建议： 1) “I'm children” 中代词和名词不匹配，正确说法是用单数“I was a child”表示过去的单一身份。建议用“I was a child”来表达“我小时候”。 2) 动词时态需一致以描述过去的经历：将“buy”改为过去式“bought”，将“I love”改为过去式“I loved”，将“go”改为过去式“went”，将“changed”改为过去式保持一致（原句已是过去式但位置与其他动词一致更自然）。 3) “MO motor” 非自然表达，应改为“motorbike”或“motorcycle”。 改进建议：注意主语是“I”，描述过去事情时全句使用过去时，代词和数要一致，常见替换：“when I was a child”，“my mom bought”，“I loved”，“when I went to high school”。

× Yes, I think the bike is very popular in my country. In the middle school and high school, the back is the most important transfer away of our students to go to the school.

✓ Yes, I think bikes are very popular in my country. In middle and high school, bikes are the most important means of transportation for students to get to school.

错误类型：主谓一致和词汇选择（列入“Subject-verb agreement errors”）。 原因与建议： 1) “the bike is very popular” 中主语应为复数“bikes”来概括大众喜好，因此动词也要与复数主语一致：“bikes are”。 2) “the back” 是拼写或词汇错误，应为“bike(s)”。 3) “the most important transfer away” 表达不自然且错误，正确表达是“the most important means of transportation”（最重要的交通工具）。 4) “to go to the school” 中不需要定冠词“the”前置，直接说“to get to school”。 改进建议：将名词复数化以泛指，注意固定搭配“means of transportation”，“get to school”更地道。
