Bike— Part 1 채점 보고서

제안: 句子有时态、代词和语法错误，表达不够自然。回答可以更直接并提供简短细节，例如确切是谁送的、何时得到的，以及你当时的感受或如何使用它。注意时态一致（过去时），代词完整，以及简洁连贯地组织句子。

예시: Yes, I had a bike when I was a child. My parents gave it to me as a birthday present when I was eight, and I used it every day to ride around the neighborhood with my friends.

제안: 总体表达清楚但有词形和细节可改进。注意主谓一致（bikes）和使用更具体的例子或原因来支持观点，例如共享单车的普及原因和使用场景，并用连接词使句子更流畅。

예시: Yes, bikes are very popular in China. For example, shared-bike services are everywhere in cities, so many people use them for short trips to work or school, which makes cycling a convenient and affordable option.

× Yes, I have a bike.

✓ Yes, I had a bike.

原句使用現在時（have），但考官問的是過去（Did you have... / when you were a child），應使用過去時態。建議根據時間線一致使用過去時，如將 have 改為 had。

× When I was a kid it was bought by my.

✓ When I was a kid, it was bought for me.

原句語序和介詞使用不正確，且缺少逗號分隔時間狀語。'bought by my' 不完整，應使用 'bought for me' 表示為我買的。建議學習被動語態常見搭配（bought for sb.），並注意時間狀語用逗號隔開。

× It was given by my parents because I want a bike for a birthday gift.

✓ It was given by my parents because I wanted a bike as a birthday gift.

句中主句是過去時（was given），從句卻用了現在時（want），時態不一致。應該把 want 改為過去時 wanted，並將 'for a birthday gift' 改為更自然的 'as a birthday gift'。建議保持主從句時態一致，使用合適的搭配短語。

× Yes, I think bike are really popular in China because you can see many share bikes on the street.

✓ Yes, I think bikes are really popular in China because you can see many shared bikes on the street.

主語複數與動詞不一致：'bike are' 應為複數名詞 'bikes are'。此外，'share bikes' 應使用過去分詞作形容詞 'shared bikes' 或 'shared bikes'；也可用 'share bikes' 作名詞短語但更自然為 'shared bikes' 或 'shared bicycles'。建議注意主語單複數搭配動詞，並使用正確形容詞形式修飾名詞。

× Many people use it every day.

✓ Many people use them every day.

前文提到複數名詞 'bikes'，代詞應用複數 'them' 而不是單數 'it'。建議保持代詞與所指名詞在人稱和數上一致。
