Bike— Part 1 Informe

Sugerencia: 先直接回答问题，再用过去时说明原因。注意区分过去和现在：用“when I was a child”和“didn't know how to ride”，不要重复“buy”或使用听起来不清楚的表达。最后可以补充现在的计划，让回答更完整、自然。

Ejemplo: No, I didn’t have a bike when I was a child because I hadn’t learned how to ride one. I’ve recently started learning, though, and I’d like to buy a bike once I feel more confident.

Sugerencia: 先明确表达“是的”，然后聚焦现在自行车在你国家是否普及。可以举共享单车或朋友骑车的例子，并说明人们骑车的原因，例如方便、环保或适合短途出行。注意使用现在时，避免加入与问题无关的童年经历。

Ejemplo: Yes, bikes are quite popular in my country, especially in big cities. Many people use public bike-sharing services, such as Hello Bike, because they’re convenient for short trips. I also see a lot of people cycling to work or to nearby shops.

× I don't have a bike before I'm child

✓ I didn't have a bike when I was a child.

这句话说的是童年时期的情况，应使用一般过去时。否定句用“didn't + 动词原形”，所以用“didn't have”；表示“当我还是个孩子时”应说“when I was a child”，而不是“before I'm child”。

× when I'm child I don't know how to ride a bike

✓ When I was a child, I didn't know how to ride a bike.

这里描述的是过去不会骑车的情况，因此应将“am”改为过去式“was”，并将“don't know”改为“didn't know”。“child”前还需要冠词“a”。

× Before I am child

✓ When I was a child

此处是在回忆童年，应使用过去式“was”。表达“当我还是个孩子时”通常用“when I was a child”；“child”前需要冠词“a”。

× my friend is have a bye

✓ My friend had a bike.

“is have”不是正确的动词形式。结合前文的过去时间，表达过去拥有自行车应使用“had”。这里按上下文将“bye”理解为“bike”；如果原意不是“bike”，请替换为正确的名词。
