自行车— Part 1 评分报告

建议: 用更自然、语法正确的句子并控制长度。回答要直接开门见山，然后用一到两句具体细节支持，避免重复。注意时态和冠词（a/an/the），以及更地道的短语（e.g. "tricycle", "transition to a two-wheeler", "neighbor"）。可用连接词但保持简洁。

示例: Yes. I had a tricycle from the age of five. My parents bought it so I could learn balance safely, and later a neighbor girl taught me how to transition to a two-wheeler.

建议: 答案要更简洁并使用准确表达。先给出直接观点，然后用一两句具体、连贯的事实或比较支持（使用正确的时间表达和集体名词），避免啰嗦和语法错误。改进词汇多样性（e.g. "widespread", "afford", "in recent decades"）。

示例: Yes, bikes used to be extremely popular in China, especially in the 1980s and 1990s when most families couldn't afford cars. In recent decades, however, rising incomes and urbanization have led many people to switch to cars or public transport.

× Yes, I started to have a bike since five years old.

✓ Yes, I got a bike when I was five years old.

句子使用了错误的时态和时间状语结构。英文中表达“在五岁时得到某物”应使用过去式（got）并用 when I was five years old 或 at five years old，而不是 started to have ... since five years old。建议使用："I got a bike when I was five years old." 或 "I had a bike from when I was five."。

× My parents bought a bike with three wheels for me so that I can learn how to ride a bike with three wheels and then I can turn to ride a bike with two wheels.

✓ My parents bought a three-wheeled bike for me so that I could learn how to ride it, and then I could switch to riding a two-wheeled bike.

句中因果关系发生在过去，主要动词应使用过去时的情态动词could而不是现在时的can；另外表达更自然的方式是 use "three-wheeled bike" 和代词 it。建议将 can 改为 could，并简化重复词。

× I learned it through a neighbor sister who owned a bike 1st and she helped me to ride a bike.

✓ I learned from a neighbor (an older girl) who already owned a bike, and she helped me learn to ride.

原句结构不自然且词序与词汇使用不当："neighbor sister" 不是地道表达，应改为 "a neighbor" 或 "an older girl"；"owned a bike 1st" 使用了不规范的序数词和位置，改为 "who already owned a bike"；末尾重复使用 ride a bike，改为 learn to ride 更简洁。建议按上述方式重写句子以符合英语习惯。

× Especially in the last century, in 1980s or 1990s, Chinese people, most of them only have bikes.

✓ Especially in the last century, in the 1980s and 1990s, most Chinese people only had bikes.

这里描述过去的事实，应使用过去时态（had）而不是现在时（have）。另外时间表达要加定冠词 the 并使用复数年代表达形式 "the 1980s and 1990s"。建议使用过去时并调整年代表达。

× They cannot afford a car.

✓ They could not afford a car.

句子在描述过去的情形，应使用过去时情态动词 could not 而不是现在时 cannot。将 cannot 换为 could not 以匹配上下文过去时间。

× So China used to be one of the countries with the most bikes.

✓ So China used to be one of the countries with the most bicycles.

句子总体使用过去时 "used to be" 正确，但“bikes”可以改为更正式的 "bicycles"（可选）。时态本身正确，因此只是建议用词更恰当。若只改时态无须更改。

× But now, as people's salary increase, more and more people are using cars.

✓ But now, as people's salaries increase, more and more people are using cars.

名词 salary 在此应为复数 salaries，因为谈论一般人群的收入变化；动词 increase 与主语 salaries 保持现在时复数形式为 increase（原句已正确），因此主要改为复数名词。建议使用 "people's salaries" 来表达更自然。
