Bike— Part 1 採点レポート

提案: 回答与问题不完全匹配：问题询问的是自行车，但你提到的是“bag”，导致核心意思不清楚。如果你想表达的是自行车，应直接说明“我有一辆自行车”，然后补充颜色、购买者和用途。注意使用正确的语法，例如“bought by my father”“to travel between school and home”和“I loved it very much”。同时，原回答是一个很长的句子，应该拆分成2—3个短句，并使用“because”或“so”等连接词。

例: Yes, I had a bike when I was a child. It was a red one that my father bought for me, and I used it to travel between school and home. I loved it because it was practical and looked really nice.

提案: 你能够直接表达“这取决于城市”，并通过平坦城市和山区城市进行对比，内容方向较好。不过，“has a lot of safety”表达不自然，建议改为“people are concerned about safety”或“cycling is relatively safe”；“cities which is flat”应改为“cities that are flat”，“use bikes for commute”应改为“use bikes for commuting”，“another city”应改为“other cities”，“built on the mountain”应改为“built in mountainous areas”。此外，句子过长，建议使用“However”或“whereas”清楚连接两个对比情况，并给出一个具体城市或原因。

例: I think bikes are quite popular in some parts of my country, but it depends on the location. In flat cities, many people use them for commuting because cycling is convenient and relatively safe. However, bikes are less common in mountainous cities, where the roads are steep and difficult to cycle on.

× I actually have a bag

✓ I actually had a bag

问题发生在过去（小时候），所以要使用一般过去时。将现在时 have 改为过去时 had。

× which is brought by my father

✓ which was brought by my father

这件事发生在过去，因此被动语态中的 be 动词要使用过去式 was，而不是现在式 is。过去分词 brought 的形式保持不变。

× for my communicate with the school and home

✓ for commuting between school and home

介词 for 后面不能直接使用动词原形或错误形式 communicate。表示“通勤”时，可以使用动名词 commuting。school 和 home 之间应使用 between。

× I love it very much

✓ I loved it very much

描述童年时期喜欢这件物品，动作发生在过去，所以 love 应改为过去式 loved。

× I actually have a bag which is brought by my father for my communicate with the school and home it was a red one I love it very much

✓ I actually had a bag that was brought by my father for commuting between school and home. It was red, and I loved it very much.

原句包含多个完整意思，但没有使用句号、逗号或连词分隔，形成了连写句。应将不同意思分成两个句子，并使用 and 连接相关内容，使句子结构清晰。

× some cities which is flat

✓ some cities which are flat

先行词 cities 是复数，所以关系从句中的 be 动词必须使用复数形式 are，而不能使用单数形式 is。

× but for another city

✓ but in another city

表示“在某个城市”时，应使用介词 in。for 不能用于表达这里的地点关系。

× use bikes for commute

✓ use bikes for commuting

介词 for 后面通常接名词或动名词。表示“骑自行车通勤”时，应使用 commuting，而不是动词原形 commute。也可以说 use bikes to commute。

× they will often use bikes for commuting

✓ they often use bikes for commuting

这里描述的是通常情况或一般习惯，不是将来发生的动作，所以应使用一般现在时。删除 will，使用 they often use。

× another city like torn which built on the mountain

✓ another city like the town that is built on the mountain

which 后面缺少被动语态中的 be 动词。表示“建在山上的城镇”时，应使用 is built。注意：torn 不是正确的普通英语单词；如果想表达“城镇”，应使用 town。

× it's not really often to use a bike

✓ it isn't very common to use a bike

often 是表示频率的副词，不能自然地用于 it is often to do sth 这种结构中。表示“使用自行车并不常见”时，应使用形容词 common，构成 it isn't very common to use a bike。
