Bike— Part 1 채점 보고서

제안: 回答前后矛盾且句子没有说完。先明确回答自己是否拥有自行车；如果想表达曾借朋友的车骑，可以用过去时说明，并补充骑车的目的或感受。避免使用“MMM”等未完成内容，尽量用一到两句清楚表达。

예시: I don’t think I owned a bike as a child, but I sometimes borrowed my friend’s. We usually rode around the neighborhood after school.

제안: 你提供了交通便利、环保和费用低三个相关理由，但重复了“convenient”，并有较多停顿和自我修正。“if because”不符合语法；可用“because”和“also”连接理由，并将“for environmental friendly”改为“environmentally friendly”。

예시: Yes, I think bikes are quite popular in my country because they’re a convenient and affordable way to get around. They’re also environmentally friendly, so many people use them for short trips.

× No, I don't think so, but I do. Umm, borrow my friend's bike to MMM.

✓ No, I don't think so, but I did borrow my friend's bike.

问题问的是你小时候的情况，因此回答中的动作也应使用过去时。这里用助动词过去式 did，而不是现在时 do。原句后面的 “to MMM” 含义不清且像是未说完的内容，因此未纳入修改。

× Yes, I do think so if because a bike is a very convenient way, convenient, uh, transportation and, uh, it's umm, for environmental friendly and it uh, doesn't cost too much.

✓ Yes, I do think so because a bike is a very convenient means of transportation, and it's environmentally friendly and doesn't cost too much.

“if” 和 “because” 不能在这里同时连接同一个原因从句。表达“因为”时保留 because 即可，删除 if。

× Yes, I do think so if because a bike is a very convenient way, convenient, uh, transportation and, uh, it's umm, for environmental friendly and it uh, doesn't cost too much.

✓ Yes, I do think so because a bike is a very convenient means of transportation, and it's environmentally friendly and doesn't cost too much.

这里需要用副词 environmentally 修饰形容词 friendly，表示“环保的”。environmental 是形容词，不能直接修饰 friendly；应说 environmentally friendly。
