自行车— Part 1 評分報告

建議: 回答切题，但有明显的时态错误：谈论童年经历应使用过去时，例如将“have”改为“had”。可以补充一个具体细节，比如谁买的、你在哪里骑，或你是否喜欢骑车。

範例: Yes, I had a bike when I was five. My parents bought me a small red one, and I used to ride it in the park near our home.

建議: 开头直接回答了问题，但回答在“through the”处中断，导致意思不完整。避免使用过多填充词（如“uh”），并把“could”改为表达普遍情况的“can”。可以说明共享单车如何使用，并补充一个受欢迎的原因，例如方便、经济或环保。

範例: Yes, bikes are very popular in China, especially in big cities. For example, people can unlock shared bikes with a mobile app and use them for short trips. They’re convenient and relatively inexpensive, so many commuters use them to get to the subway or nearby shops.

× Sure, I have a bike when I was 5.

✓ Sure, I had a bike when I was 5.

句子中的“when I was 5”表示过去的时间，因此“have”应使用过去式“had”。描述过去拥有某物时，注意让动词时态与过去时间表达保持一致。

× First, uh, there are many shared bikes in the street and everyone could use a bike through the.

✓ First, there are many shared bikes in the street, and everyone can use them.

句末的“through the”没有接上后续内容，导致句子结构不完整。由于无法确定原本想表达的具体地点或方式，修正时删去这个未完成的部分。这里用“them”指代前面的共享单车，并用“can”表达共享单车目前可供大家使用。
