Bike— Part 1 채점 보고서

제안: 回答切题，但要注意过去时：讲童年经历时用“had”和“was”，不要用“have”和“is”。避免重复“it has”，并把细节表达得更自然；如果你指的是儿童用的四轮自行车，可以说明它有辅助轮。

예시: Yes, I did. I had a yellow bike when I was a child, and it had two small training wheels to help me keep my balance.

제안: 先直接回答自行车是否受欢迎，并注意主谓一致：可以说“bikes are popular”。“cannot avail build the cars”表达不自然；如果想说买不起汽车，可用“cannot afford to buy a car”。避免把原因说得过于绝对，并补充一个具体原因或例子。

예시: Yes, bikes are quite popular in my country. Many people ride them because they are cheaper than cars and convenient for short trips, especially in busy cities.

× I have a bike when I was a child.

✓ I had a bike when I was a child.

句子描述的是“小时候”的情况，时间在过去，因此动词 have 应使用过去式 had。

× It is yellow and it has it has four wheels.

✓ It was yellow, and it had four wheels.

这里继续描述小时候那辆自行车的颜色和特征，应使用过去时：is 改为 was，has 改为 had。重复的“it has”属于口语重复，整理句子时可删去。

× I think it's very popular, because most of them cannot avail build the cars, so they just ride a bike.

✓ I think bikes are very popular because most people cannot afford to buy cars, so they just ride bikes.

bikes 是复数，不能用单数代词 it 指代，应使用 they，或直接重复 bikes。原句中的 them 容易被理解为指代 bikes，但这里表达的应是“多数人”，所以改为 most people。

× I think it's very popular, because most of them cannot avail build the cars, so they just ride a bike.

✓ I think bikes are very popular because most people cannot afford to buy cars, so they just ride bikes.

情态动词 cannot 后面不能直接接“avail build”这样的动词组合；表达“买不起”应使用 afford to do，即 afford to buy。cars 泛指汽车时通常不需要加定冠词 the。
