自行车— Part 1 评分报告

建议: 回答直接且理由清楚，但时态和表达略显重复。“when you were a child”对应过去经历，建议统一使用过去时，例如用“had never learned”或“never learned”。此外，前面已经说没有自行车，结尾的“so I don't have one”重复了同一信息，可以删掉。

示例: No, I didn’t. I never learned how to ride a bike when I was a child, so I didn’t own one. I suppose I missed out on a fun way to get around.

建议: 观点明确，也提供了便利和价格方面的理由，但有几处语法和搭配问题：“ride back”应改为“ride bikes”，“convenient to use”可改为“convenient”，而“there are many shared bikes alongside the road make...”应改为“there are many shared bikes along the roads, which make...”。建议使用“because”和“besides”等连接词，并避免重复使用“use”。

示例: Yes, bikes are quite popular in my country, especially in large cities. Many people ride them to commute because they are convenient and inexpensive. Besides, shared-bike services are widely available along the streets, which makes cycling an easy option for short journeys.

× Actually, I didn't have a bike because I have never learned how to ride a bike, so I don't have one.

✓ Actually, I didn't have a bike because I had never learned how to ride a bike, so I didn't have one.

问题描述的是学生童年时的情况，因此相关动词应使用过去时。将现在完成时“have never learned”改为过去完成时“had never learned”，表示在童年那个过去时间点之前从未学会骑自行车；将现在时“don't have”改为过去时“didn't have”，以保持与问题和前文的时态一致。

× Yes, I have noticed many people ride back to commute.

✓ Yes, I have noticed that many people ride bikes to commute.

“ride back”通常表示“骑车返回”，不符合这里“骑自行车通勤”的意思。应使用“ride bikes to commute”。在“noticed”后加入“that”也能使宾语从句结构更加清晰、完整。

× It's convenient to use and not expensive.

✓ They are convenient to use and not expensive.

前文提到的是复数名词“bikes”，所以应使用复数代词“They”，而不能使用单数代词“It”。“They are convenient to use”表示“它们使用起来很方便”。

× Besides, there are many shared bikes alongside the road make it easier for people to use it.

✓ Besides, there are many shared bikes alongside the road that make it easier for people to use them.

“there are many shared bikes”后面直接接“make”会造成两个动词结构连接不当。应加入关系代词“that”，构成“bikes that make...”的定语从句，说明这些共享单车的作用。

× Besides, there are many shared bikes alongside the road make it easier for people to use it.

✓ Besides, there are many shared bikes alongside the road that make it easier for people to use them.

“shared bikes”是复数名词，因此指代它们时应使用复数宾格代词“them”，不能使用单数宾格代词“it”。
