自行车— Part 1 評分報告

建議: 回答切题，并且提供了原因、时间变化和具体经历，内容较充实。需要注意代词和主语的一致性：前文一直用“I”，所以“we learned to ride”应改为“I learned to ride”。另外，“after I grew stronger”与“a few years later”连续使用略显重复，可以简化时间表达，使句子更自然。建议使用“Eventually”或“Later”连接经历，并明确说明哥哥是如何帮助你的。

範例: Yes, I had a bike when I was a little girl, although I couldn’t ride it at first because my legs were quite weak. Eventually, I got stronger and bought another bike a few years later. My brother helped me learn to ride in our yard, so it became a really memorable childhood experience.

建議: 回答直接，使用了转折词“but”和“while”，并且通过北京这一具体例子补充说明，逻辑清晰。主要问题是语法：应说“In a big city like Beijing”或“In big cities like Beijing”，不能说“In big city”。此外，可以更直接地先回答“是的，很受欢迎”，再补充不同类型自行车的使用情况，这样结构会更符合口语回答习惯。

範例: Yes, I think bikes are quite popular in my country, especially in large cities. For example, in Beijing, many people use regular bicycles and shared bikes for short journeys. Although electric bikes are sometimes restricted for safety reasons, cycling is still a convenient and environmentally friendly way to travel.

× When I was a little girl I did have a bike, but I couldn't ride it at first because my leg was too weak. So I ended up selling it after I grew stronger and a few years later I bought another one and we learned to ride with my brother's help in the yard.

✓ When I was a little girl, I did have a bike, but I couldn't ride it at first because my leg was too weak. So I ended up selling it after I grew stronger, and a few years later I bought another one and learned to ride with my brother's help in the yard.

这里的“we learned to ride”会让人理解为“我和哥哥一起学骑车”，但根据语境，应该是“我在哥哥的帮助下学会骑车”，所以应使用第一人称单数“I learned”。逗号只是为了改善句子的可读性，不属于本题要求的语法错误类型。

× At first I thought bicycles weren't very popular in our country, but later I realized I was wrong. In big city like Beijing, electric bikes are often restricted for safety reasons, while regular bicycles and shared bikes are widely used.

✓ At first I thought bicycles weren't very popular in our country, but later I realized I was wrong. In a big city like Beijing, electric bikes are often restricted for safety reasons, while regular bicycles and shared bikes are widely used.

“city”是可数名词单数，前面需要使用冠词。这里表示“像北京这样的一座大城市”，因此应在“big city”前加不定冠词“a”，形成“a big city like Beijing”。
