自行车— Part 1 評分報告

建議: 句子时态和语法错误较明显，回答也过于简短且缺少细节。建议使用正确的时态（过去式）并给出一到两句具体补充说明，例如谁拥有、为什么没有或是否后来看过往。可以用连接词使回答更流畅。

範例: No, I didn't have a bike when I was a child. My family couldn't afford one at the time, so I usually walked to school or took the bus. Later, when I was a teenager, I finally bought a second-hand bike.

建議: 总体意思明确但表达略显笼统且时态不一致（“used to”暗示过去习惯，但可补充现在情况）。建议用更具体的细节支持观点，并使用连接词（for example, because, although）来增强连贯性。

範例: Yes, bicycles are very popular in my country because they are cheap and convenient. For example, many people use bikes for short commutes in the city, and bike-sharing programs have become common in recent years.

× I don't have a bike when I was a child.

✓ I didn't have a bike when I was a child.

问题类型：现在时使用错误（应为过去时）。原句使用了现在时的否定形式 “don't have” 与从句的过去时间状语 “when I was a child” 时间不一致。正确做法是将动词改为过去式 “didn't have”。建议：当句子表示过去发生的状态或动作时，使用过去时，例如 “didn't have / I didn't go”。

× It's really popular in my country.

✓ They're really popular in my country. (或者：Bikes are really popular in my country.)

问题类型：现在时搭配与主语不一致。原句中的代词 “It” 是单数，但问题谈论的是复数名词 “bikes”。应使用复数主语和相应的复数代词或直接使用名词：“They are” 或 “Bikes are”。建议：注意代词须与所指名词的单复数一致，或直接重复名词以避免歧义。

× People used to use it to commute.

✓ People used to use them to commute. (或者：People used to use bikes to commute.)

问题类型：过去时/代词单复数问题。句中使用了过去习惯表达 “used to”，这是正确的过去时用法，但随后使用的代词 “it” 与复数名词 “bikes” 不一致。应使用复数代词 “them” 或直接说 “bikes”。建议：复查代词与先行词在数上的一致性；谈论一般群体事物时通常使用复数形式。
