Bike— Part 1 Báo cáo

Gợi ý: 回答不够自然与清晰，时态和表达有误。应直接回应并提供简短细节，避免语法错误和歧义。例如说明什么时候有、是否仍然有以及与童年相关的回忆。

Ví dụ: Yes, I did. I had a red bicycle when I was about eight, and I kept it for three years because I used it to ride to school and play with my friends.

Gợi ý: 内容明确但语言可更自然和具体。注意细节表达（例如 'environmentally friendly'，'to work'），并用连词使回答更流畅。可以加入具体例子或对比来丰富答案。

Ví dụ: Yes, I think bicycles are very popular in my country because they are environmentally friendly and cheap to maintain. For example, in the mornings many office workers and students ride bikes to work or school, especially in crowded cities where cycling is faster than driving.

× Yes, I had and I have kept for three years.

✓ Yes, I had one and kept it for three years.

原句混用了过去时和现在完成时结构，且省略了宾语，造成不清楚和时态不一致。首先回答“Did you have a bike when you were a child?”需要用过去时，因此“I had”是正确的。要表达“我保存了三年”，应使用过去时“kept”并加上宾语“it”（指代自行车）：“I had one and kept it for three years.” 建议：保持时态一致并补全缺失的宾语。

× bikes are environmental friendly and also convenient.

✓ bikes are environmentally friendly and also convenient.

“environmental friendly”是不正确的搭配，应该使用副词形式修饰形容词，即“environmentally friendly”。因此应写“environmentally friendly”表示“对环境友好”。建议：当形容词前需要一个副词修饰时使用副词形式（-ly）。

× In the morning you can see various people riding their bikes to works.

✓ In the morning you can see various people riding their bikes to work.

短语“to works”不正确，固定搭配是“to work”表示去上班或去学校，work在这里作不可数名词表示地点/活动，不加复数。应写“to work”。建议：注意固定搭配，某些表示去上班/上学的短语用单数或不可数形式（to work/to school）。
