Bike— Part 1 採点レポート

提案: 回答需要直接且语法正确。你的回答不自然且有语法错误（“I'm back when I was a child” 不正确）。可以用一句主题句直接回答，再补充一到两句具体细节，例如什么时候有、是谁给的或骑自行车的回忆。长度控制在不超过5句，并使用衔接词如“and”或“when”。

例: Yes, I did. I got my first bike when I was seven, and I learned to ride it in the park near my house. I used to ride it to visit my friends every weekend.

提案: 回答要更具体并提供理由或例子。避免简单的“yes”句，把主题句扩展为包含原因或比较的句子，并使用衔接词如“because”或“so”。可以说明流行的原因（环保、交通拥堵、成本低等）或举例说明哪些人常骑自行车。

例: Yes, they are. Bikes are very popular because they are cheap and convenient for short trips, and many people use them to commute to work or school in the city.

× Yes, I'm back when I was a child.

✓ Yes, I had one when I was a child.

问题类型：句子结构错误（26）。原句“I’m back when I was a child.”不符合英语表达习惯。这里考问过去是否拥有自行车，应使用一般过去时和动词“have”的过去式“had”。“I’m back”字面意思是“我回来了/我还在”，与问题含义不符。建议：用“I had one”或“I had a bike”来表示过去拥有，保持时态一致。

× Yes, it is very popular in my country.

✓ Yes, they are very popular in my country.

问题类型：主谓一致（27）。原句用“it is”指代“bikes”，但“bikes”是复数，应使用复数代词“they”并配合复数动词“are”。建议：将代词和动词改为复数形式：“They are very popular”或直接说“Bikes are very popular in my country.”
