自行车— Part 1 評分報告

建議: 回答较为自然但存在语法、流畅性和信息组织问题。应注意时态一致（过去式）、避免重复填充词（uh, like, I think），并把信息按主题句+具体细节的顺序陈述。可以用一到两句补充具体细节（比如年龄、谁买的、学会骑车的经历）并用连接词（for example, because, so）使表达更连贯。总句子不超过5句。

範例: Yes, I had a bike when I was a child. It was a small red tricycle with one wheel in front and two at the back, which helped me keep my balance. My parents bought it for my fifth birthday, and I practiced on it in our backyard until I learned to ride a real bicycle.

建議: 回答简短且含糊，表达有重复和语法问题。应先直接回答（Yes/No and reason），然后用一到两句具体支持细节（例如谁使用、在什么情况下、替代交通工具是什么、城市与乡村差异）。避免重复词汇并使用连接词（but, however, because, for short distances）。控制在不超过5句。

範例: Not really — bicycles are more common among older people for short trips because they are convenient and cheap. In cities many people prefer electric scooters or motorcycles for longer distances, while bikes remain popular in parks and small neighborhoods for leisure.

× Yeah, actually I have a bike with like 4 wheels, uh, one at front, three at behind, so it can help me balance before I can fully learn how to ride the bike. It, it is a red bike I think.

✓ Yeah, actually I had a bike with four wheels, uh, one in front and three behind, so it helped me balance before I could fully learn how to ride a bike. It was a red bike, I think.

这是关于过去时的错误。题目问的是“当你是小孩时”，叙述应使用过去时态。原句使用现在时（have, can, is），与时间状语“when you were a child”不一致。建议将动词改为过去式：have→had，can→could，help→helped，is→was，并修正介词短语（in front, behind）和数字写法以更自然、规范的表达。

× one at front, three at behind

✓ one in front and three behind

这是介词使用错误。英语中描述物体位置通常用 in front（在前面）或 behind（在后面，常不接介词）。原句用法不自然且多余介词。建议使用固定搭配“in front”和单词“behind”。

× ride the bike

✓ ride a bike

这是冠词使用问题。当泛指任何一种自行车时，英语中应使用不定冠词 a/an 而不是定冠词 the。原句用“the bike”暗指特定自行车，但语境是泛指学习骑车，改为“ride a bike”。

× The elderly like to ride a bike when they come on road and when the distance is short

✓ Elderly people like to ride bikes when they are on the road and when the distance is short

这是单复数和名词搭配问题。英文中通常用“elderly people”或“the elderly”作为复数群体，单独用“the elderly like to ride a bike”在数的一致性和可数名词上不够自然；此外“ride a bike”改为复数或泛指“ride bikes”。“come on road”也不自然，应为“are on the road”。建议说“Elderly people like to ride bikes when they are on the road and when the distance is short”。

× otherwise they may use the electrical vehicle electrical bike.

✓ Otherwise they may use an electric vehicle or an electric bike.

原句单词选择和句子结构不当。“electrical vehicle”不是常用搭配，应为“electric vehicle”；重复“electrical”也造成冗余。并且需要连接词或并列结构来表达两种可能的交通工具。建议改为“an electric vehicle or an electric bike”。
