Bike— Part 1 Informe

Sugerencia: 回答过去的经历时，要用过去时态。这里应说“Yes, I did”，而不是“Yes, I have”。可以再补充一个具体细节，例如自行车的颜色或你骑车的地点，让回答更完整。

Ejemplo: Yes, I did. I had a small red bike, and I used to ride it around my neighborhood.

Sugerencia: 先直接回答问题，并注意用“bikes”而不是“spikes”、用“my country”而不是“my countries”。后半部分有重复和不清楚的表达；描述你观察到的情况时，可以说“I often see...”或“Many children...”，并用一个连接词说明原因。注意使用完整、准确的句子。

Ejemplo: Yes, I think bikes are popular in my country. I often see young children learning to ride them, especially in parks, because cycling is a fun way to exercise.

× Yes, I have.

✓ Yes, I did.

问题问的是过去的经历（“Did you have...?”），回答时应使用助动词 did，而不是现在完成时助动词 have。回答过去时的一般疑问句时，通常用相同的助动词简短作答。

× I think spikes are popular in my countries.

✓ I think spikes are popular in my country.

这里说的是“我的国家”，应使用单数 country。countries 表示多个国家，与此处表达的意思不符。

× The one when I AM 77 years old I see many children to to to buy bike when they are very very small.

✓ When I was 77 years old, I saw many children buying bikes when they were very young.

“The one when...”不能自然地引出这个完整句子，删去“The one”并用“When...”引导时间状语从句，句子结构会更清楚。

× when I AM 77 years old I see many children

✓ when I was 77 years old, I saw many children

这句话是在回忆过去的经历，因此应使用过去时：am 改为 was，see 改为 saw。

× I see many children to to to buy bike

✓ I saw many children buying bikes

see 后面接宾语时，可以用“宾语 + 动词-ing”表示看到某人正在做某事。这里不应在 children 后使用 to buy。口语中可删去重复的 to，并使用 buying。

× children ... buy bike

✓ children ... buy bikes

bike 是可数名词。这里泛指孩子们买自行车，且主语 children 是复数，因此通常用复数 bikes。

× when they are very very small

✓ when they were very young

句子描述的是过去看到的情景，所以应将 are 改为过去式 were。这里用 young 描述孩子的年龄也比 small 更自然。
