Bike— Part 1 Báo cáo

Gợi ý: 句子时态和语法混乱，存在词汇错误（如 back -> bike）和句子结构不完整。回答没有清晰的主题句与连贯的支持细节，信息表达不够准确。改进建议： 1) 使用正确时态（过去时）描述童年经历； 2) 纠正词汇错误（使用 bike）； 3) 把信息分成1-2个简短句子，第一句作主题句，第二句提供具体细节并用连接词（e.g. but, so）使结构连贯； 4) 控制在最多5句内，避免重复； 5) 可补充一两项具体细节（颜色、年龄、发生了什么）以丰富内容。

Ví dụ: Yes, I had a bike when I was a child. I got a pink bike when I was eight, but it broke when I was twelve, so my mother bought me a new black-and-green one.

Gợi ý: 词汇和拼写错误（write backs -> ride bikes / backs -> bikes），句子重复且细节不足。改进建议： 1) 使用正确词汇 ride bikes 或 bicycles； 2) 用连接词扩展原因或具体场景（e.g. because, for example）； 3) 提供具体细节或比较（如时间、地点、原因或百分比估计）来支持观点； 4) 保持回答简洁、自然，最多5句。

Ví dụ: Yes, bicycles are very popular in my country. For example, many people ride bikes to work or school every morning and evening because cycling is cheap and convenient.

× Yes, of course when I was eight I will have a pink back, but when I grow up, I'm 12 that that back was broke. So my mother bought me a new one is a black and a green.

✓ Yes, of course. When I was eight I had a pink backpack, but when I was 12 that backpack was broken. So my mother bought me a new one that was black and green.

错误类型：将来时使用错误（应使用过去时） 说明：学生在叙述过去发生的事情时错误地使用了“will have”（将来时），正确的应该用一般过去时“had”。另外句中“I'm 12”应为过去时“I was 12”；“back”应为“backpack”；“was broke”是形容词/动词混用，正确为“was broken”；最后部分冗余且词序不当，改为“that was black and green”。改进建议：回忆过去发生的事时统一使用过去时（如：had, was, bought）；注意名词拼写（backpack）和被动结构（was broken）。

× Yes, it's very popular in my country. Every morning and every night there are so many people write backs. Backs.

✓ Yes, it's very popular in my country. Every morning and every night there are so many people riding bikes.

错误类型：现在时及动词形式错误 说明：句子中“write backs”不是正确表达。这里应使用现在时的一般现在分词结构“riding”来表示正在骑自行车的动作，且“backs”应为“bikes”或“bicycles”。原句时态（一般现在）可以保留，因为是在陈述习惯性事实。改进建议：把错误的动词和名词改为正确形式：“riding bikes”（骑自行车）；保持一般现在时描述习惯性动作。
