自行车— Part 1 评分报告

建议: 用更自然和连贯的方式回答，避免多余的词（如“uh”）并注意时态一致。先直接回答问题的主题句，然后用一到两句话具体说明细节（如年龄、谁给的、学车的经历），并用连接词使句子衔接更好。注意使用过去时描述童年经历。

示例: Yes, I did. When I was very young my parents bought me a four-wheeled training bike with two small wheels at the back to help me balance. Later, around the age of eight, I switched to a regular two-wheeled bike and learned to ride on quiet streets.

建议: 回答要更具体并使用更丰富的词汇，避免填充词（如“umm”,“you know”）。可先给出总体看法，再提供具体例子或原因（如共享单车、城市通勤、环保等），并用连接词如“because”或“for example”增强逻辑。注意名词复数和冠词使用（many cities）。

示例: Yes, I think bikes are very popular in China because they are convenient and cheap. For example, many cities have extensive bike lanes and widespread public bike-sharing systems, which people use for short commutes and errands.

× Yes, we know I was little.

✓ Yes, when I was little.

原句中短语顺序和用词不当。使用“we know”在此处不符合上下文，且时态应为过去时。改为“When I was little”是常见的表达童年时的时间状语，从而使句子通顺自然。建议：描述过去经历时用“when I was + age/小/young”等固定结构。

× I have uh, I have a four wheel bike.

✓ I had, uh, a four-wheel bike.

原句使用现在时“have”与前面表明过去的时间点（when I was little）不一致，应使用过去时“had”。另外“four wheel”作为复合形容词需用连字符，写作“four-wheel”。建议：描述过去持有物品时使用过去时态；复合形容词前加连字符。

× There's two extra uh wheels at the back to help children balance

✓ There were two extra wheels at the back to help children balance.

原句使用“There's”=“there is”（单数）但后面跟复数“two wheels”，且句子是在过去的语境，应使用过去复数形式“There were”。建议：主语是复数或过去时要匹配相应的“there be”形式。

× and when I get older I have a normal bike.

✓ and when I got older I had a normal bike.

句子叙述过去的经历，应将现在时“get”和“have”改为过去时“got”和“had”。建议：保持同一叙述时态一致，讲过去经历时全部使用过去时。

× Yes, umm, in China many city have bikes.

✓ Yes, umm, in China many cities have bikes.

原句中“city”应为复数“cities”以与“many”搭配，属于名词单复数使用错误（复数形式问题，归类为介词/结构使用下的复数问题）。建议：使用“many”时，名词需用复数形式；注意城市复数拼写（city→cities）。

× People ride bikes on the road and there are even, you know, uh, public bikes.

✓ People ride bikes on the road, and there are even public shared bikes.

原句总体可理解，但“public bikes”在这里不够准确，通常说法为“public bikes”或“public shared bikes”/“public bike-sharing bikes”。此外需要加连接词逗号使句子更流畅。我将其改为“public shared bikes”更明确表示共享自行车。建议：使用常见搭配如“public/shared bikes”或“public bike-sharing systems”。
