Bike— Part 1 Informe

Sugerencia: 回答直接，但“a one”用法不正确。这里应说“a bike”，因为“one”不能和不定冠词“a”连用来代替 bike。可以补充一个具体细节，例如自行车的颜色或你通常骑车做什么，让回答更自然、完整。

Ejemplo: Yes, I had a bike when I was a child. It was red, and I often rode it around my neighborhood.

Sugerencia: 先直接回答问题，不要用“Exactly”开头；可改为“Yes, I think so”。注意名词和动词形式：“mountain bikes”要用复数，“off-road cycling”比“off road cycle”自然，“trails nearby”中的 trails 要用复数。描述过去经历时用“I started”，描述现在的习惯时用“I still ride”，并说“with my friends on weekends”。建议把答案分成几句，并用“because”或“For example”连接具体理由，避免一句话塞入过多信息。

Ejemplo: Yes, I think bikes are quite popular in my country, especially mountain bikes. Many people enjoy off-road cycling, and there are several trails near my city. I started riding when I was seven, and I still go cycling with my friends on weekends.

× Yes, I had a one.

✓ Yes, I had one.

这里的 one 代替前文提到的 bike，已经是代词，前面不能再加不定冠词 a。可以说 “I had one”，也可以说 “I had a bike”。

× Exactly, I think mountain bike are quite popular in my country because many people enjoy off road cycle and there are a lot of trail nearby.

✓ Exactly, I think mountain bikes are quite popular in my country because many people enjoy off-road cycling and there are a lot of trails nearby.

此处泛指许多山地车，因此 mountain bike 应使用复数 mountain bikes。a lot of 后面接可数名词复数，所以应说 a lot of trails。描述一般性的活动时，nearby 前的 trail 也应使用复数 trails。注意，修改为 mountain bikes 后，与 are 的单复数搭配也正确。

× Exactly, I think mountain bike are quite popular in my country because many people enjoy off road cycle and there are a lot of trail nearby.

✓ Exactly, I think mountain bikes are quite popular in my country because many people enjoy off-road cycling and there are a lot of trails nearby.

enjoy 后面通常接动名词（动词-ing 形式），所以不能说 enjoy cycle，应说 enjoy cycling。这里 off-road 作复合形容词修饰 cycling，通常加连字符。

× I start riding one when I was 7 and I still ride with my friend on weekend.

✓ I started riding one when I was 7, and I still ride with my friend on weekends.

when I was 7 表示过去的时间，因此 start 应使用过去式 started。描述过去开始、现在仍持续的情况时，可以说 “I started … when I was 7, and I still …”。

× I start riding one when I was 7 and I still ride with my friend on weekend.

✓ I started riding one when I was 7, and I still ride with my friend on weekends.

表示通常在周末骑车时，常用复数 weekends，表达为 on weekends。也可以说 on the weekend。
