Bike— Part 1 채점 보고서

제안: 句子时态和语法有错误，表达不自然。回答也较简短且结构混乱，应直接回答问题并用一到两句补充原因，注意时态一致、连贯性和句子完整性。可以将负面事实（没有自行车）作为主题句，然后用because引出具体原因，避免句子断裂。

예시: No, I didn’t have a bike when I was a child because our apartment was very small and there wasn’t anywhere to store it. Besides, my parents preferred me to use public transport for safety reasons.

제안: 回答总体内容相关且有例子，但有语法、用词和连贯问题（如“probably you shared”、“stockless bikes”不合适）。应先给出清晰简短的主题句，然后用连词引出具体原因和例子，使用恰当词汇（e.g. shared bikes, dockless bikes, cycle around）并注意句子简洁自然。

예시: Yes, bicycles are very popular in my country. In particular, many people use dockless shared bikes for short trips in city centres because they are cheap and convenient, and they help avoid traffic and parking problems.

× No, I never have a bike when I was a child because there is no space to. Park the bike in my house.

✓ No, I never had a bike when I was a child because there was no space to park it in my house.

句子使用过去时态描述过去的情况，主句与从句须一致。原句中使用了“have”（现在时）与“is”（现在时），但问题是过去发生的事，应该用过去时“had”和“was”。此外，句子被错误地拆成两部分并且不必要的大写“Park”。建议：把动词改为过去式（have → had；is → was），并将不完整的短句合并，代词“it”用来指代“a bike”。

× Yes, probably you shared. Bicycles are very common on streets these days, especially in city centres where people prefer them to for short trips.

✓ Yes, probably. Bicycles are very common on the streets these days, especially in city centres where people prefer them for short trips.

原句“You shared”与上下文无关并且语义混乱，可能是口误，应删除。另有介词使用问题（见下）。建议删去无关短语，句子更连贯自然。

× Bicycles are very common on streets these days, especially in city centres where people prefer them to for short trips.

✓ Bicycles are very common on the streets these days, especially in city centres where people prefer them for short trips.

英语中“on the streets”通常需要定冠词“the”表示泛指的街道集合；短语“prefer them to for short trips”包含多余的介词“to”，正确用法是“prefer A for B”或“prefer A to B”。在此处应使用“prefer them for short trips”表示“在短途出行时更喜欢自行车”。建议：使用定冠词“the”，并删除多余的“to”。

× For example, many commuters use stockless bikes to travel to walk around areas because they are cheap and convenient.

✓ For example, many commuters use dockless bikes to travel and walk around areas because they are cheap and convenient.

原句中“stockless”应为“dockless”（无桩停放的共享单车），且动词结构“to travel to walk”不正确，造成重复不连贯。建议将并列动作用连词连接如“travel and walk around”，或只用“travel around”。同时注意词汇选择正确。
