自行车— Part 1 评分报告

建议: 回答要更符合语法并更简洁，同时提供一到两句补充细节以丰富内容。注意时态一致（过去用过去式），避免多余词汇（如“hasn't enough more”应为“didn't have enough”）。可用连接词如“because”, “so”, 或“therefore”来使句子更连贯。举例说明什么时候想要一辆自行车或如何获得它，可以增加内容的具体性。

示例: No, I didn't. My family couldn't afford a bike when I was a child because money was tight, so I usually walked to school or shared rides with my friends.

建议: 回答要保持时态和语法一致，句子更简洁流畅。避免口头语（如“uh”），用连接词如“although”或“nowadays”来对比过去和现在。用更准确的词汇（electric bike或e-bike）并给出具体观察或原因（如便捷、省力、便宜的充电成本）来增强内容的说服力。

示例: Bikes used to be very popular in my country, but nowadays e-bikes are more common because they are more convenient and save effort, so you see many e-bikes parked along the streets.

× No, I didn't, because when I was young my family hasn't enough more money to buy it.

✓ No, I didn't, because when I was young my family didn't have enough money to buy one.

这是过去时态错误。句子描述的是过去的情况，应使用过去时：把“hasn't”改为过去式“didn't have”。另外，‘enough more’是不自然的搭配，多余或重复，改为“enough money”。最后，代词用“one”更自然。改进建议：回想过去的时间点时，全句尽量使用过去时态（did/didn't + 动词原形）。

× I mean, it costs very high in that period.

✓ I mean, it cost very much in that period.

时态和用法不一致。句中‘that period’指过去，应使用过去式“cost”。形容费用高要用副词或固定搭配，英文中常说“cost a lot”或“cost very much”，而不是“costs very high”。改进建议：描述过去价格时用过去式并用自然搭配，例如“cost a lot”或“was very expensive”。

× It's so expensive.

✓ It was so expensive.

时态不一致。上下文在讲过去，应把现在时“is”改为过去时“was”。改进建议：保持时态一致，若前文为过去背景，后续描述也用过去时。

× No, I think in the past the bike is was very popular in our country,

✓ No, I think in the past bikes were very popular in our country,

包含多重错误：时态、主谓一致和多余单词。‘is was’重复且矛盾，应使用过去式‘were’来配复数主语‘bikes’。另外将“the bike”改为复数“bikes”更符合泛指。改进建议：表达过去普遍现象用过去时复数形式，例如‘bikes were’。

× but now the electricity by electrical bike was more popular in China.

✓ but now electric bikes are more popular in China.

措辞和语序不自然：‘the electricity by electrical bike’是错误的表达，应使用“electric bikes”。此外句子描述现在的情况，应使用现在时态“are more popular”。改进建议：学习常见词组‘electric bike(s)’，并根据时间状况选择现在或过去时。

× You can see, uh, there are many electrical bikes in the street.

✓ You can see there are many electric bikes on the street.

主要是介词和词形问题：将“electrical bikes”改为更常用的“electric bikes”；地点介词应为“on the street”而非“in the street”（两者都可，但在这里“on the street”更自然）。此外这是一个陈述现在事实的句子，时态保持现在即可。改进建议：记住形容词形式“electric”用于车辆，常用介词搭配‘on the street’或‘in the streets’，根据语境选择。
