Bike— Part 1 採点レポート

提案: 回答基本直接，也给出了原因，但“born in a very, very poor family”不自然，应改为“come from a very poor family”；“We can't afford it”时态应与过去经历一致，改为“We couldn't afford one”。避免重复使用“very”，也不需要说“sorry”。可以再补充一个具体结果，使答案更完整，例如说明你当时如何出行。

例: No, I didn't have a bike when I was a child because I came from a very poor family, and my parents couldn't afford one. Instead, I usually walked to school or took the bus.

提案: 答案回应了问题，但存在明显的语法、词汇和表达重复。“bikes”是复数，应该用“They are”；“a transport, a transportation”和“It's a vehicle”表达不自然且意思重复。应直接说明自行车受欢迎的原因，并使用具体细节，例如通勤、锻炼、环保或共享单车。可以用“Moreover”或“especially”连接补充信息。

例: Yes, bikes are quite popular in my country, especially in large cities. Many people cycle to work or use shared bikes because they are affordable, convenient, and environmentally friendly. They are also popular for exercise and short trips.

× Actually, I didn't have a bike because I was born in a very, very poor family.

✓ Actually, I didn't have a bike because I was born into a very, very poor family.

表示“出生于某个家庭”时，英语通常使用介词“into”，而不是“in”。“be born into a family”是更正确、自然的表达。

× We can't afford it, sorry.

✓ We couldn't afford it, sorry.

前文使用了一般过去时“didn't have”和“was born”，表示童年时期的情况。因此，情态动词“can”也应使用过去式“could”，即“couldn't”。

× We can't afford it, sorry.

✓ We couldn't afford it, sorry.

这件事发生在过去，所以“afford”前应使用过去时情态动词“couldn't”，而不是现在时形式“can't”。

× Yeah, it's very popular in my country.

✓ Yeah, they're very popular in my country.

“bikes”是复数名词，因此要用复数代词“they”，不能用单数代词“it”。相应的系动词也应使用“are”，缩写为“they're”。

× In my country, bikes are not only a a transport, a transportation.

✓ In my country, bikes are not only a means of transportation but also vehicles.

“a a”是重复使用冠词，必须删除一个。“transportation”通常是不可数名词，不能直接说“a transportation”。“a means of transportation”表示“一种交通工具或交通方式”，是正确表达。

× In my country, bikes are not only a a transport, a transportation. It's a vehicle.

✓ In my country, bikes are not only a means of transportation but also vehicles.

“not only”通常需要和“but also”搭配，表示“不仅……而且……”。原句缺少“but also”，所以句子结构不完整。由于主语“bikes”是复数，后面的“vehicles”也应使用复数形式。

× It's a vehicle.

✓ They are vehicles.

这里的主语指前面的复数名词“bikes”，所以不能使用单数代词“it”。应使用复数代词“they”，并将“vehicle”改为复数“vehicles”。

× People use it for many, many uses.

✓ People use them for many, many uses.

“it”是单数代词，而它所指的“bikes”是复数名词，因此应改为复数代词“them”。
