Bike— Part 1 Informe

Sugerencia: 句子时态有混用，表达不够简洁流畅，且信息重复。回答应直接使用过去时描述童年经历，随后用一两句具体细节支持。注意连接词与句子长度控制（不超过5句）。可改进词汇如“ride a bike”替换为“cycled”或“went cycling”。

Ejemplo: Yes, I did. I had a bicycle when I was a child and I used to go cycling on weekends. My mother often cycled with me to the market, and we would sometimes stop at a park to play, which was always enjoyable.

Sugerencia: 时态与语序混乱，应用清晰的比较句型来表达过去与现在的对比，并使用准确词汇（e-bikes 或 electric bikes）。可以加入一两条具体原因或结果来丰富内容，例如城市化、公共交通和收入变化。控制在最多5句内，使用连接词如“however”或“nowadays”。

Ejemplo: They used to be very common, but nowadays fewer people ride traditional bicycles. Over the past two decades, many people have switched to electric bikes and cars because cities have grown and incomes have risen, making motorized transport more convenient.

× Yes, I have and I often ride a bike.

✓ Yes, I did, and I often rode a bike.

原句时态混乱。考官问的是过去是否有自行车，应使用一般过去时。用“have”表示现在拥有，与问题时态不符。改为“did”表示过去有过；第二部分描述童年时常做的动作也应为过去时“often rode”。建议：在描述过去的习惯或状态时一律使用一般过去时。

× I often ride a bike when I have a free time on weekends and my mother often rode a bike with me to go shopping and have fun.

✓ I often rode a bike when I had free time on weekends, and my mother often rode a bike with me to go shopping and have fun.

句中时态不一致：第一部分使用现在时“ride/ have”，第二部分使用过去时“rode”。根据上下文（谈论童年），应全部用一般过去时。此外“a free time”中“time”不可与不定冠词连用，应为“free time”。建议：保持时态一致，去掉不必要的冠词。

× 20 years before there are there were many bikes on the streets in China, but now more people prefer to electric, electrical bikes and cars.

✓ Twenty years ago there were many bikes on the streets in China, but now more people prefer electric bikes and cars.

原句问题包括多项： 1) 时间表达错误：“20 years before”不自然，应该用“Twenty years ago”。 2) 多余重复：“there are there were”重复并混淆时态，应使用“there were”。 3) 词语选择错误：“prefer to electric”不正确；“prefer”后要直接跟名词或动词不定式（如“prefer electric bikes”或“prefer to use electric bikes”）。 4) “electrical bikes”词形不常用，通常说“electric bikes”。建议：用“Twenty years ago”引出过去情况，使用“there were”表达存在，使用“prefer electric bikes”或“prefer to use electric bikes”。
