Bike— Part 1 Relatório

Sugestão: 答题要直接回应问题并使用正确时态；注意发音与词汇（bike 而非 bag），结构要更连贯。可以用一到两句直接回答（有或没有），随后用1–2句具体说明原因或经历，使用连接词（for example, because, so）。避免重复和语法错误。

Exemplo: I didn’t have my own bike when I was a child. Instead, I often borrowed bikes from my family because my parents and grandparents shared theirs or sold them when they no longer needed them.

Sugestão: 答案要更清晰、有条理并用具体细节支持观点。注意重复词汇、语法和词汇准确性（bags → bikes）。用连接词（for the past, nowadays, because）把句子连起来，提供具体事实或例子（例如共享单车的普及和家庭拥有率）。保持句子不超过五句。

Exemplo: Yes, bikes are very popular in China. For the past thirty years many families have owned one or two bikes for parents to use. Recently, the rise of bike‑sharing services has made cycling even more widespread in cities because it is cheap and convenient.

× When I was a child, I don't have my own bag.

✓ When I was a child, I didn't have my own bag.

句子叙述的是过去的情况，主句使用过去时态，因此“do not have”不合时，应使用过去时“didn't have”。建议：回顾一般现在时与一般过去时的时态一致性，当描述过去发生的事情或过去的状态时，用过去时态。

× I didn't have my own bike.

✓ I didn't have my own bike.

该句本身时态正确，无需修改。保持过去时表明过去没有自行车。

× I just ride.

✓ I just rode.

句子描述的是过去发生的动作，应使用动词的过去式“rode”而不是现在时或动名词。建议：描述过去动作时用动词过去式。

× My mother and my grandma sold bikes when they didn't need them.

✓ My mother and my grandma used to sell bikes when they didn't need them.

原句'sold'可以表达过去卖掉的单次动作，但结合“when they didn't need them”更自然用“used to sell”表示过去经常性的行为。建议：区分一次性过去动作（sold）与过去经常性动作（used to + 动词）。

× Yes, umm bikes are very popular in China among among now for the past 30 years almost uh, family have one, one family have one to two bags for the so for the parents.

✓ Yes, bikes have been very popular in China for almost the past 30 years. Nearly every family has one or two bikes for the parents.

句子混合了现在完成进行/现在完成时与一般现在时，且主谓不一致。应使用现在完成时态“have been”表示过去持续到现在的状态，并用“has”配合单数名词“every family”。另外“bags”应为“bikes”。建议：使用现在完成时描述过去一段时间持续到现在的情况；注意主语与动词单复数一致；检查词汇拼写。

× And nowadays we have more mobile bikes for umm, and there are a lot of mobile bikes nowadays in China.

✓ And nowadays we have more shared (mobile) bikes, and there are a lot of them in China.

原句中“for umm”无谓且造成句子不完整；重复使用“nowadays”亦可精简。还需要明确“mobile bikes”应为“shared bikes”或“bike-sharing services”，并用代词“them”避免重复。建议：去掉多余的介词/短语，使用恰当名词并用代词替代重复名词。
