Bike— Part 1 Báo cáo

Gợi ý: 句子多次时态和表达混用，且结尾不完整。建议：1) 使用正确的时态（过去式）并避免重复；2) 用一到两句补充具体细节（如外观、记忆或感受）；3) 保持答案自然简洁（不超过5句），并用连接词使逻辑更流畅。示例结构：主题句（过去拥有）+1-2个具体细节+感受或结果。

Ví dụ: Yes, I did. I had my first bike when I was seven; my father bought it for my birthday. It was bright red with a small basket, and I remember feeling very proud because I could ride to school by myself.

Gợi ý: 回答总体清楚但有语法和表达细节问题：1) 改正“it's cost is”为“their cost is”或“they are relatively cheap”；2) 使用连接词丰富论证（例如：“because... therefore...”或“so”）；3) 给出更具体例子或对比（比如城市/乡村使用差异），以增加内容深度。保持1-2个支持细节。

Ví dụ: Yes, I think bikes are quite popular in my country because they are relatively cheap and convenient for short trips. For example, many students and office workers cycle to school or work to avoid traffic and save money, especially in crowded cities.

× I have I have a bike when I was a child.

✓ I had a bike when I was a child.

原句使用了现在完成时（have）与过去时间状语（when I was a child）冲突。描述过去的经历应使用一般过去时。建议将 have 改为过去式 had，以与“when I was a child”一致。

× It is my first bike when I was 7 years old and the bike is brought from my father.

✓ It was my first bike when I was 7 years old and the bike was brought by my father.

句中讲述的是过去的情况，应使用一般过去时：is → was。另一个问题是被动结构用法：brought from my father 不自然，英语中表示礼物来源常用 by。将 is 改为 was，并把 brought from 改为 was brought by。

× This is my birthday gift from him.

✓ This was my birthday gift from him.

上下文为过去叙述，应把现在时 is 改为过去时 was，使句子时态与前后保持一致，句子本身有动词 be，但时态不对。

× I was very.

✓ I was very happy.

原句不完整，缺少表语，导致结构不完整。需要在 very 后加形容词（如 happy）来完成句子。建议写出具体情感： very happy / very excited 等。

× because it's cost is relatively cheaper than other transportation tools

✓ because its cost is relatively lower than that of other means of transportation

原句有几处问题：1) its 写作时不应有缩写 it's（it is），这里需用物主代词 its；2) cost 与比较结构应用 lower than 或 cheaper than，但 cheaper 已含比较义，前面不宜加 relatively 更常用 relatively low 或 relatively cheaper（不太地道）；3) other transportation tools 表达不自然，应改为 other means of transportation 或 other modes of transport；4) 比较对象需明确，可用 that of 来指代“其他交通工具的费用”。建议改为 its cost is relatively lower than that of other means of transportation。

× and when people go to work or school they can choose to take a bike.

✓ and when people go to work or school they can choose to ride a bike.

动词选择问题：英语中通常说 ride a bike 而不是 take a bike。句子时态和情态动词 can 是正确的，但动词搭配应改为 ride。
