Bike— Part 1 채점 보고서

제안: 回答直接、语法基本正确，也符合“先回答、后补充细节”的结构。可以进一步说明你什么时候开始骑车、如何使用这辆自行车，增加具体性。注意“a bicycle that my parents bought me”虽然正确，但可以用更自然的表达“a bike my parents bought for me”。

예시: Yes, I did. I had a blue bike that my parents bought for me when I was about six. I used to ride it around my neighborhood with my friends after school.

제안: 观点和原因比较清楚，但表达中有多次“umm”，影响流利度和自然度。注意主谓一致：如果主语是“bikes”，应说“they are quite popular”，而不是“it's quite popular”。“it's not cheap to get a ride”与语境不符，应该表达为“it's cheap to ride a bike”或“it saves money”。“especially in a popular city”不自然，可以改为“especially in large cities”。结尾“use the shared bike to”不完整，应说“use shared bikes”或“use bike-sharing services”。建议使用“because”和“as a result”等连接词，并加入一个具体例子。

예시: Yes, I think bikes are quite popular in my country because they are practical, affordable, and environmentally friendly. This is especially true in large cities, where traffic is often heavy. As a result, many people use shared bikes for short trips, such as commuting to work or going to the subway station.

× Yes, I think so umm it's quite popular because it's very practical and it's not cheap to get a ride umm especially in a popular city umm and it's also friendly to the environment, so a lot of people use the shared bike to.

✓ Yes, I think so. Umm, they are quite popular because they are very practical, and it's not cheap to get a ride, especially in a popular city. They are also friendly to the environment, so a lot of people use shared bikes, too.

前文的主语是复数名词“bikes”，所以后面不能用单数代词“it”来指代自行车。应使用复数代词“they”。同时，第二个“it's”也应改为“They are”，因为它指的是复数的自行车。

× Yes, I think so umm it's quite popular because it's very practical and it's not cheap to get a ride umm especially in a popular city umm and it's also friendly to the environment, so a lot of people use the shared bike to.

✓ Yes, I think so. Umm, they are quite popular because they are very practical, and it's not cheap to get a ride, especially in a popular city. They are also friendly to the environment, so a lot of people use shared bikes, too.

“bikes”是复数主语，因此系动词应使用复数形式“are”，不能使用单数形式“is”。例如：“Bikes are popular”，而不是“Bikes is popular”。

× Yes, I think so umm it's quite popular because it's very practical and it's not cheap to get a ride umm especially in a popular city umm and it's also friendly to the environment, so a lot of people use the shared bike to.

✓ Yes, I think so. Umm, they are quite popular because they are very practical, and it's not cheap to get a ride, especially in a popular city. They are also friendly to the environment, so a lot of people use shared bikes, too.

这里是在泛指共享自行车这一类交通工具，不是指一辆特定的自行车，所以应使用复数形式“shared bikes”。使用复数可以更清楚地表达“很多人使用共享单车”。
