Bike— Part 1 Báo cáo

Gợi ý: 回答内容切题，也给出了姐姐骑车和自己请求妈妈买车的具体原因。注意核心词应为“bike”，不是“back”；通常说“in kindergarten”“ride a bike to school”，不需要加定冠词。可减少重复使用“when”，并用过去时和连接词让叙述更自然。

Ví dụ: Yes, I had a bike when I was a child. I wanted one after seeing my older sister ride hers to school. So I asked my mother to buy me a bike, and she did.

Gợi ý: 回答提到了过去和现在的对比，这是很好的思路，但要先直接回答现在自行车是否受欢迎。注意复数应说“bikes”，过去时可说“were popular”；“everyone”后需要完整谓语，如“rode”。“electronic bags”应为“electric bikes”。删除重复词，并补充一个具体原因或对比。

Ví dụ: Yes, bikes are still popular in my country, although electric bikes are more common now. When I was a child, many people rode regular bikes to work or school. These days, people often choose electric bikes because they can travel longer distances with less effort.

× Yes, I had the back when I was a child.

✓ Yes, I had a bike when I was a child.

第一次提到一辆自行车时，应使用不定冠词 a，而不是定冠词 the。这里根据上下文将 back 按原意理解为 bike；back 本身是词汇问题，不属于所列语法类型。

× When I was in the kindergarten, I was very eager to have a bike when I saw my elder sister riding bike to the school.

✓ When I was in kindergarten, I was very eager to have a bike when I saw my elder sister riding a bike to school.

泛指上幼儿园这一阶段时，通常说 in kindergarten，不加 the。ride 后面的 bike 是可数名词单数，前面需要冠词；表示去上学时通常说 go to school，不加 the。

× When I was in the kindergarten, I was very eager to have a bike when I saw my elder sister riding bike to the school.

✓ When I was in kindergarten, I was very eager to have a bike when I saw my elder sister riding a bike to school.

bike 是可数名词单数，不能在没有限定词的情况下单独使用，应说 a bike。

× The backs was were very popular when I was a child.

✓ Bikes were very popular when I was a child.

主语是复数，be 动词应使用 were。原句中的 was 和 were 同时出现也不正确，应保留与复数主语一致的 were。这里根据上下文将 backs 按原意理解为 bikes；backs 本身是词汇问题，不属于所列语法类型。

× At that time everyone riding backs to to work or to school.

✓ At that time, everyone rode bikes to work or to school.

At that time 指过去的时间，描述过去经常发生的动作时，应使用一般过去时 rode。原句的 riding 不能单独充当句子的谓语。这里根据上下文将 backs 按原意理解为 bikes；重复的 to 属于重复输入，不在所列语法类型中。
