自行车— Part 1 評分報告

建議: 回答时要注意时态和年龄描述的准确性，内容要更直接并连贯展开。可以用一到两句总述，然后用一到两句具体细节（比如什么时候得到、是谁给的、为什么想要）并使用连接词以增强逻辑。例如纠正为过去时并避免不必要重复。

範例: Yes, I did. I got my first bike when I was nineteen — it was a gift from my grandmother. I wanted it because all my friends had bikes, so I asked her and she kindly agreed to buy one for me.

建議: 回答要更明确地区分现在与过去的情况，使用连接词（for example, because, so）并给出具体细节和简单比较。用完整句并注意语法（时态、人称单数）。

範例: Yes, I think bikes used to be very popular, especially in the 1980s in Chengdu. For example, my mother had a bike which helped her commute to work, but nowadays more people use cars or public transport.

× Yes, when I'm 19, I have a first bike.

✓ Yes, when I was 19, I had my first bike.

句中描述的是过去的经历，应使用一般过去时。原句用了现在时（I'm, have），时态不一致。改为 "was" 和 "had" 来表示过去发生的事情。建议：回忆过去事件时，使用过去时，例如："When I was 10, I lived..."。

× The bike is from my grandmother.

✓ The bike was from my grandmother.

这里在讲述过去的事件，应该使用过去时态。原句使用一般现在时 "is" 不符合叙述过去获得物品的情境。建议：描述过去的来源或归属时用过去时："It was a gift from..."。

× One day I see my friend, everybody have a bike, but I don't have, so I want a bike.

✓ One day I saw my friends; everybody had a bike, but I didn't, so I wanted a bike.

句中描述的是过去发生的事情，应全部用过去时。原句混用了现在时（see, have, don't, want）。另外复数形式和标点需调整（friends 比 friend 更自然）。建议：叙述过去时保持动词一致使用过去式，如 "saw, had, didn't, wanted"。

× I told my grandma, she said.

✓ I told my grandma and she said yes.

原句缺少时态完整性与连接词，且省略了宾语或后续内容。应使用过去时并补全含义或用连接词连接两部分。建议：使用连词并保持过去时，如 "I told her, and she said yes/that she would buy me one."。

× I think bikes are popular in my country in 1980s everybody have a bike in Chengdu.

✓ I think bikes were popular in my country in the 1980s; everybody had a bike in Chengdu.

这里谈的是过去（1980s），谓语要用过去时。原句使用现在时 "are/ have" 不合时态。并且 "1980s" 前通常加定冠词 the。建议：表示过去的普遍事实用过去时，并在年份十年代前加 "the"。

× For example my mom have a bike, it help her to go to work.

✓ For example, my mom had a bike; it helped her to go to work.

句中 "mom" 是单数，动词应与主语一致且在描述过去事件时用过去时。原句用了现在时 "have/ help"，并且缺少逗号或分号。建议：主语为单数时动词形式要对应，且叙述过去事件时用过去时："my mom had... it helped..."。
