Bike— Part 1 Báo cáo

Gợi ý: 句子需要更自然和语法正确。避免多余词汇，保持一到三句即可。可以直接回答并加一两个具体细节，例如谁送的、什么时候收到或对你的意义。注意语法：‘had back when’ 应改为 ‘had when’ 或 ‘had when I was a child’；‘which from my parents’ 应改为 ‘which was from my parents’ 或更简洁的 ‘a birthday gift from my parents’。

Ví dụ: Yes, I did. I received a bicycle from my parents for my tenth birthday, and I used it to ride to the park near our house.

Gợi ý: 回答总体清晰但可改进用词和连贯性。注意搭配和词形：’costly effective’ 应为 ‘cost-effective’；加入连接词使句子更流畅；提供更具体的例子或数据会更好，比如在哪些城市或人群更常见，或提到基础设施如自行车道。保持不超过五句。

Ví dụ: Yes, they are. Bicycles are widely used in cities for daily commuting because they are cost-effective and convenient, and many urban areas have dedicated bike lanes that make cycling safer.

× Yes, sure I had back when I was a child.

✓ Yes, sure — I had one when I was a child.

句中缺少宾语“one”（指代一辆自行车），导致单复数或省略名词的错误。应补上可数名词的代词或名词以使句子完整。建议在提到具体物品时使用适当的代词（如one）或名词（如a bike）。

× It was a birthday gift which from my parents.

✓ It was a birthday gift from my parents.

句中使用了关系代词which后又接介词from，结构重复且不自然。应直接用介词短语修饰名词："a birthday gift from my parents"。如果要用定语从句，可改为"which was from my parents"。

× Many people commute by bike because it's costly effective and convenient and it's also eco friendly since it produces no emissions.

✓ Many people commute by bike because it's cost-effective and convenient, and it's also eco-friendly since it produces no emissions.

“costly effective”是不正确的搭配，正确表达是“cost-effective”（有成本效益的）。另外，复合形容词在作定语时通常用连字符（cost-effective, eco-friendly）。建议记住常见固定搭配并注意连字符的使用。
