自行车— Part 1 評分報告

建議: 用更自然、時態正確且條理分明的句子回答；開頭先直接回答問題（主題句），然後用一到兩個具體細節支持。注意時態一致（描述過去經歷用過去式），避免重複和語法錯誤，並使用連接詞使句子更流暢，例如“when”、“then”、“so”、“but”。可以控制在最多五句內。

範例: Yes, I did. I had a small bike when I was a child and there were tricycles at my kindergarten. When I started primary school I switched to a two-wheel bike, but by junior high I wasn’t very confident riding it. During holidays I often rode with my friends in the park, which was a fun way to exercise and socialize.

建議: 回答要更準確、詞彙選擇要正確（如 bike 而不是 back），並提供具體例子支持觀點。先給出直接答案，再解釋原因，最後舉例說明（如共享單車的具體用法）。保持語句連貫，避免語法錯誤並使用連接詞如“because”、“for example”。限制在五句以內。

範例: Yes, bikes are very popular in my country because they are cheap and convenient, especially in crowded cities. For example, parking a car can be difficult and expensive, but bikes are easy to park. There are also many bike-sharing services, like Hello Bike, which you can unlock with an app and use for short trips.

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

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

句子中时间点是“when I was a child”（过去），因此主句应使用一般过去时“had”而不是现在时“have”。建议根据时间状语一致使用过去时：When + past → use past tense。

× It's about have 4 cycles in my kindergarten and it changed to two cycle when I was in primary school.

✓ There were about four bicycles at my kindergarten, and it changed to two bicycles when I was in primary school.

原句中量词和名词形式不正确（'4 cycles' 应为 'four bicycles' 或 'four cycles' 但更常用 bicycles），且句子结构混乱。使用表示存在的结构“there were”更符合英语习惯。注意数词用单词形式较正式，且复数名词要加 -s。建议：使用 'there was/were' 表示过去存在，并确保名词与数一致。

× But I'm not good at riding it when I was in junior high school and in the in the holidays we often I often ride bike with my friend in the park.

✓ But I wasn't good at riding it when I was in junior high school, and during the holidays we often rode bikes with my friends in the park.

句子含多个问题：时态与时间状语不一致（过去情景应使用过去时 'wasn't'、'rode'）；第三人称单数错误体现在 'friend' 与实际指代不符且应为复数 'friends'；语序和冗余（'we often I often'）需删去。建议按照过去背景统一使用过去时态，并保持主谓一致与复数形式。

× Yes, I think back is very popular and it's very convenient.

✓ Yes, I think bikes are very popular and they're very convenient.

原句将 'bikes' 写成 'back'（拼写错误为词汇错误，属代词/名词选择问题）且主语为复数应使用复数动词 'are' 和复数代词 'they're'。建议注意单词拼写并保持主谓一致。

× Sometime the car may be hard to parking but the back is very convenient.

✓ Sometimes cars may be hard to park, but bikes are very convenient.

句中 'hard to parking' 语法错误，正确结构为 'hard to park'（不定式动词原形），并且 'the car' 与上下文应为泛指复数 'cars'；'back' 应为 'bike(s)'。建议用不定式原形作表语补足，注意名词单复数和拼写。

× And there's a lot of free bicycle in my country, maybe named Hello car and you can just sync in your phone and you can write it.

✓ And there are a lot of free bicycles in my country, maybe called Hello Bike; you can just sync it with your phone and unlock it.

原句存在多处问题：'there's' 与复数 'a lot of bicycles' 不一致，应为 'there are'；'free bicycle' 应为复数 'free bicycles'；'named' 用法不自然，常用 'called'；'sync in your phone' 介词错误，应为 'sync with your phone'；'you can write it' 不合适，应该是 'unlock it' 等更符合语境。建议注意主谓一致、介词搭配及用词自然表达。
