自行车— Part 1 评分报告

建议: 注意时态和语法一致（应使用过去时），避免重复和冗余，句子要更简洁并直接回应问题。可以先用主题句回答，然后用一两句具体细节补充（例如自行车的颜色、类型和为什么没有山地车）。使用连接词使表达更连贯。

示例: Yes. I had a large white bike when I was a child. I wanted a mountain bike, but my parents thought it would be difficult to get on and off, so they bought me a big, simple bike instead.

建议: 注意用词和表达更自然，避免直译句式（如“has no height”不自然），提供更具体例子或数据使内容更有说服力，同时使用连接词让衔接更顺畅。

示例: Yes, bikes are very popular, especially in Tianjin, because the city is very flat which makes cycling easy. Many people use bikes for short trips to work or the market since they are cheap and environmentally friendly.

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

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

句中时态不一致：从句“when I was a child”使用过去时，主句也应使用过去时，而原句用现在时的“have”。此外缺少冠词“a child”。建议：在描述过去的情况时，主句和从句都用过去时，且注意必要的限定词（a/the）。

× when I was child I have a giant white bike

✓ when I was a child I had a giant white bike

缺少冠词“a”放在“child”前。英文中可数名词单数前通常需要冠词或其他限定词。建议：养成在单数可数名词前检查是否需要a/an/the或其他限定词。

× I always wanted a mountain bike but my parents wouldn't get me one because they told me that it's hard to get on and off.

✓ I always wanted a mountain bike but my parents wouldn't get me one because they told me that it was hard to get on and off.

主句和从句时态应一致。主句是过去时（wanted, wouldn't get），从句用现在时“it's hard”不合适，应该用过去时“it was hard”。建议：间接引语或在过去背景下描述一般情况时，把从句相应地改为过去时。

× Tianjin is a city that has no height and very flat on roads.

✓ Tianjin is a city that is very flat and has low elevation.

原句中“has no height”和“flat on roads”的表达不地道且介词使用不当。“flat”通常不与“on roads”连用来描述整个城市地形，应说“is flat”或“has low elevation”。建议：用更自然的短语描述地形，如“is very flat”或“has low elevation”。

× So people travel by bike a lot here and bikes are economic and friendly to the environment.

✓ So people travel by bike a lot here and bikes are economical and environmentally friendly.

形容词“economic”用于指经济学或与经济相关，不适合描述物品节约资源，应使用“economical”。此外“friendly to the environment”更自然的短语是“environmentally friendly”。建议：区分“economic”（经济的，国家层面）与“economical”（节省的、经济实惠的），并使用固定搭配“environmentally friendly”。

× So instead they got me enormous bike bike.

✓ So instead they got me an enormous bike.

名词单复数与冠词错误：原句缺少不定冠词“an”，并且重复了“bike”。建议：单数可数名词前加a/an，根据首音使用an，同时注意不要重复单词。
