Bike— Part 1 채점 보고서

제안: 先直接回答是否有自行车，并保持过去时态一致。注意语法：应说“my mother bought it for me”，而不是“It's my mother I bought for me”；骑车上学要说“rode my bike to school”，不能说“buy bike to school”。可补充一个具体细节，例如自行车的颜色或你骑车去哪里。

예시: Yes, I had a bike when I was a child. My mother bought it for me, and it was bright red. I rode it to school almost every day and really enjoyed it.

제안: 直接用“bikes”回答，并避免反复使用“I often”和过多填充词“uh”。“我看到很多人”应说“I see a lot of people”；注意复数形式“bikes”。可以补充具体原因或场景，例如城市交通拥堵、骑车通勤或共享单车的普及。

예시: Yes, bikes are quite popular in my country, especially in big cities. I often see people cycling to work or using shared bikes for short trips. They are convenient and help people avoid traffic.

× Yes, when I was a child. I have a bike.

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

问题询问的是小时候的经历，且时间状语是“when I was a child”，因此应使用过去时。这里的“have”应改为过去式“had”。可以根据明确的过去时间线索检查动词时态。

× It's my mother I bought for me.

✓ My mother bought it for me.

原句中“I”被用作“bought”的主语，但按句意应由“my mother”执行“买”的动作；“it”指代自行车，作“bought”的宾语。注意根据代词在句中的作用选择主格或宾格，并明确动作的主语。

× I often buy bike to school.

✓ I often buy a bike to school.

“bike”是可数名词单数，前面通常需要限定词。这里应在“bike”前加不定冠词“a”。单数可数名词不能通常单独出现。

× I think bike is very popular in my country.

✓ I think bikes are very popular in my country.

这里是在泛指自行车这一类事物，应使用复数“bikes”，并相应搭配“are”。谈论一类事物时，通常可以使用复数名词。

× Many people buy bike in the city.

✓ Many people buy bikes in the city.

句子泛指许多人购买自行车，单数“bike”不能在这里无冠词地使用。应改为复数“bikes”。检查可数名词是否需要复数词尾或限定词。
